Universitas Muhammadiyah Bandung


Abstract

Technology growth today make any information can arrive in second. This benefit make another problem come where the information not filtered. It makes user overloaded information, therefore user need to filter it by them self. This activity make lot of time wasted. To solve this problem, should there is a system that can filter the information and sort them based on its priority. With this system, user no need to filter the information and the information that shown are already sorted by its priority.

Analytical Hierarchy Process (AHP) is one of Multi Criteria Decision Making (MCDM) algorithm that can making decision based on several criteria or to prioritize alternative than others. AHP will use to prioritize all the information in database based on user criteria. But there is a problem where AHP strongly depend on user input. So to solve this problem, AHP will collaborate with Naïve Bayes Classifier who mining the content of information and propose the information as alternative to AHP algorithm. With this collaboration proved that information can prioritize without user input with the interval from system and user priority for four interval space.

Danny Henry Galatang, Suyanto

Telkom University


Abstract

In the last decade, researchers show that a syllable-based automatic speech recognition (ASR) give higher accuracy than phoneme-based ASR for English, Tamil, and some other languages. In this research a syllable-based ASR is developed for Indonesian, a syllable-rich language with 3.20 syllables per word on average (standard deviation 0.41), and be compared to a phoneme-based ASR. Both ASRs are implemented using SPRAAK, an ASR engine developed by ESAT KU Leuven, with Hidden Markov Model (HMM)-based acoustic model and trigram language model. Evaluation on 5,439 words read-speech corpus shows that monosyllable-based ASR give word accuracy 76.57%, significantly higher than the monophone-based ASR with accuracy 63.36%. It means that monosyllable-based ASR produces absolute improvement of word accuracy by 13.21%. The monosyllable-based ASR can be extended to bisyllable or trisyllable to improve the word accuracy. However, huge bisyllable or trisyllable acoustic models should be developed and managed efficiently using an advanced method.

Balanced Sentence Set Based on Syllables and Punctuations using Greedy Algorithm
Bagus Nugroho Budi Nurtomo, Suyanto

Telkom University


Abstract

A read speech corpus used to train a syllable-based automatic speech recognition system should be collected using an optimum sentence set balanced on syllable and punctuation. The optimum sentence set is commonly extracted from millions unique sentence using an optimization algorithm to get minimum number of syllables with balanced frequencies. A widely used optimization algorithm called Least-to-Most (LTM) Greedy algorithm focuses on minimizing the number of syllables, but ignores balancing their frequencies. In this paper, two schemes are proposed to improve the performance of LTM Greedy. The first scheme is designed to reduce the number of sentences and the second one to balance syllable frequencies. Evaluation on a mother sentence set of 10 million Indonesian sentences shows that those schemes perform well as they are designed. A simple Pareto optimization is applied to get the optimum extracted sentence sets which are better or, at least, equivalent to LTM Greedy algorithm for both monosyllable and bisyllable regarding to the number of sentences as well as syllables frequencies.

Algorithm to trigger a number of rules based on antecedent lengths as forward chaining engine implementations on any rule-based system
Aslan Alwi

Universitas Muhammadiyah Ponorogo
Student at Universitas Gadjah Mada


Abstract

This paper proposes an algorithm for triggering a rule among a number of rule options that must be triggered first to obtain the fastest possible reasoning path. This algorithm starts from attempting to use a rule-based system to represent a generalized finite state automata. In this way of view, when a generalized finite state automata is declared, each instruction represented by a rule where the state and the input string are placed on the antecedent side and the following states are placed on the consequent side. In general, this algorithm is intended to trigger the rule in general. The proposed algorithm is expected to be used for any rule based system including expert system. The algorithm is built on the assumption that a set of rules have different antecedent lengths and antecedents consist of several premises that are operated by "and" operations. The trigger rule is done with the assumption that the longest antecedent rule is the rule that has the greatest probability to solve the problem or the fastest conclusion is obtained, so the algorithm trigger rule always starts with the longest antecedent then the next longest antecedent so on until the problem is solved or failed. The algorithm is expected to be used to construct inference systems against any rule-based system that satisfies the algorithms assumptions.

Abstract

Efficiency of solar cell greatly depends on input spectrum irradiance and its interaction with solar cell surface. For highly efficient solar cell, absorption of input light should be maximum . Different texturing techniques like inverted pyramid, nano pillars, nano cones etc have been used to increase absorption of light in solar cell. Among them hole surface texturing seems to be most promising technique. In this paper, effect of varying air mass on hole textured solar cells performance is studied. By varying air mass input solar spectrum irradiance is changed which results in a change in output of solar cell .It has been observed that by varying air mass from AM1.0 to AM1.5 efficiency of solar cell decreases due to decrease in input spectrum irradiance and less absorption of light from surface. Results are also compared with plane surface solar cell. Hole textured solar cell showed better performance than plane surface solar cell at normal angle of incidence.

Institut Teknologi Telkom Purwokerto


Abstract

Microwave is a kind of wireless communication using radio link transmission at high frequency medium between two base stations in cellular systems. Microwave link should be line of sight (LOS) between transmitter and receiver (no obstacle). But, in the real case, there are some obstacles in microwave link between two base stations. Therefore, this paper uses a microwave passive repeater to solve the obstacle problems. The passive repeater is used to repeat information signals by changing the direction of the radio link transmission. This paper implements Barnett Vigants and ITU-R P.530-7/8 methods in passive repeater using software simulation. The difference between two methods is the availability value due to multipath and unavailability value due to rain. On a microwave transmission network using the Barnett Vigants method, resulting higher unavailability value than the use of ITU-R method P.530 7/8. The unavailability value using Barnett Vigants method obtained was 0.023%, it means the outage time of link microwave is 7244 second per year. If compared with metode ITU-R P.530 7/8 method, the unavailability was 0,000087 % or outage time system is for 26 second per year. So the availability using ITU-R P.530 7/8 method is 99, 9999133%.

Abstract

This paper presents the efficiency of using LED light bulbs when operated under two different residential electrical systems: AC and DC systems. More specifically, this paper looks at whether having a hybrid AC and DC system in a typical urban house will increase the efficiency in operating the LED light bulbs, and thus reducing energy consumption. The efficiency of the LED light bulbs are measured by looking at their lumens per watt output. Several light bulbs at four different wattage levels were tested. For the DC light bulbs, further tests were performed at two voltage levels: 12V and 48V. Results indicate the importance of selecting the proper converters when DC system is to be used in a hybrid AC/DC house. Results also demonstrate the critical choice of DC voltage level when DC electrical distribution system is to be installed inside the hybrid house.

Suroso, Daru Tri Nugroho and Winasis

Universitas Jenderal Soedirman


Abstract

This paper presents a different configuration of a three-level current-source inverter (CSI). Using the proposed circuit configuration, the total number of the inverter device count is reduced. The gate or base drive power supplies are simpler than the conventional H-bridge current source inverter because almost all of the switching devices are connected at a common -emitter line. In addition, a perfect modified sinus operation can be achieved using this topology compared with the previous circuits topology. Some computer simulation test results are presented in this paper. The computer simulations were carried out using PSIM Software. The simulation results show that the circuit works well generating a three-level output current waveform, which proves feasibility of the proposed inverter circuits.

Abstract

In the electric power system, voltage is one indicator of the balance between power generated by total system load demand. If an imbalance occurs then the voltage will drop. System voltage drops of 150 kV and 70 kV have a tolerance standard of + 5% and -10% of nominal voltage. The voltage in the transmission subsystem Cibatu IBT 3 - 4 and Mandirancan when the peak loads would experience relatively unfavorable conditions. Some busbars experience voltage drops through the lower limit set by PLN. The lowest voltage value in 150 kV Cibatu IBT 3 - 4 and Mandirancan is 133,88 kV that is Dawuan busbar, whereas in 70 kV Cibatu IBT 3 - 4 and Mandirancan system goes by 58,65 kV which is Rengasdengklok busbar. Load shedding is one solution to overcome the situation. The load-shedding simulation in this research was done manually with the help of Electric Transient and Analysis Program (ETAP) software 12.6.0. In this research, there are 5 load-shedding scenarios. One of the load-shedding scenarios is to remove the highest reactive load on each 150 kV busbar experiencing undervoltage below the standard. The voltage on the Dawuan bus increased to 135.06 kV and the voltage on the Rengasdengklok bus increased to 63.45 kV.

Indonesia University of Education


Abstract

Solar energy is a renewable energy that can be converted into electrical energy called photovoltaic. This solar energy will never run out and can be found during the day making it suitable to be an alternative in the generation of electrical energy. This energy conversion uses a device called a solar panel. Solar panels are a tool used to generate electrical energy with a source of energy from solar energy. However the application of solar panels in the generation of electrical energy will not be optimal if it does not take into account the variables that affect solar panels. Variables that affect the effectiveness of solar panels include the intensity of light, temperature, azimuth angle and the slope to the ground. Therefore it is important to consider these variables in the application of solar panels in everyday life so that the resulting output can be optimal. In this study the researchers will examine the influence of temperature variables and the slope of the solar panel on the resulting output. This study aims to determine the effect of temperature variables and slope variables on the optimization of solar panels. This test is carried out for 2 months with research done every day at 09.00 to 15.00 and measured power output every 30 minutes. The tilt of the solar panels is always changed on a daily basis and its power output is measured. The results of this study will show how much influence the temperature and slope of the output on solar panels.

Abstract

Design of Water Pump System Using Solar Cell
Water is one of the basic human needs, both from daily necessities such as drinking, cooking, and sanitary necessities and the need for agriculture. The availability of adequate water for the community is sometimes a problem, especially for areas where the availability of limited water sources or groundwater sources is far from residence. Although water pumps are available nowadays and easy to get, but the availability of power is the problem, especially for areas that have not reached the network of Perusahaan Listrik Negara (PLN). Although there is a network of State Electricity Company (PLN) but the cost of pumping water operation is getting bigger day. To prevent this required solution, one of them is using solar electric technology.
The solar energy that God provides for mankind especially in Indonesia as a country with a tropical climate is abundant. In addition to abundant and not used up, solar energy also does not cause pollution so that solar energy is very potential to be utilized as a substitute for oil, coal, and others. Solar energy can not be directly utilized directly, to utilize solar energy into electrical energy, still needed equipment such as solar cells (solar cell) to convert solar energy into electrical energy. It is in accordance with the first law of thermodynamics which states that "energy can not be created or destroyed but can be transformed from one form to another (converted)".

Based on the background that has been the authors described above, then in this thesis project the authors will design the water pump system using solar cell as an effort to obtain alternative energy and used as irrigation irrigation for farmers. This design will the authors describe in a thesis report writing with the title "Designing Water Pump System Using Solar Cell"

Abstract

Energy is one of the things used as a supporter of human life can not live without the energy. Using technology, humans can cultivate and utilize the energy is wrong in the generation of electrical energy. PT. PLN Persero recorded the number of power plants in Indonesia as many as 5,765 generators spread across the territory of Indonesia.
The power supply to the consumer must go through the control process before going through the transmission and distribution channels, the frequency and the voltage to be distributed must be controlled first to fit the needs of the consumers and stable. This control can be performed using Proportional, Integral, and Derivative (PID) controllers.Frequency is a factor that must be considered in the power system before it reaches the consumer in order to avoid damage to consumer devices. Therefore, the frequency is influenced by the stability of the rotation of the generator in order to avoid overload caused by the increasing demand of electrical energy demanded by the customer as the burden to be served. Therefore it is necessary to "Load Frequency Control" (LFC) which can control the rotation of the generator. LFC can be controlled by using a frequency sensor, as a parameter to enable LFC and then ordered Valve Control Mechanism to set the valve as a valve that can determine how much incoming natural source to turn the turbine and drive the generator.

Voltage drop can occur also in the excitation system on diode commutation. The results obtained on the excitation system has occurred in the commutation drop, which caused some factors that exist on the machine (generator) itself. However, the falling voltage that occurs is about 2.85 volts for the lowest value and 3.43 volts for the highest value and the average range of 3.17 volts. Judging from the high low-drop voltage that occurs, this does not have a very big impact on generator field disturbance. With a relatively small error, the generator can still work under optimal conditions.

Abstract

The power transformer is an important component in the power system, as it is directly related to the reliability of the electric power system operation. Therefore, the diagnosis of disturbances in power transformers is important for device safety as well as electrical system stability. Dissolved Gas Analysis (DGA) is a disruptive diagnostic technique in power transformers that has been recognized effectively, because it provides knowledge of the state of the transformer based on the dissolved gas content in the transformer oil. The DGA test results can be represented by different methods such as Doernenburg ratio, Rogers ratio, IEC ratio, Duvals triangle, and key gases. The problem presented here is that two methods namely Doernenburg ratio and Rogers ratio, for the same data inputs give two different results from the error diagnosis to know the actual state of the transformer. In this paper, a combination method is proposed to solve the problem of conflict between Doernenburg ratio and Rogers ratio by utilizing multi-layer artificial neural network perceptron to localize and identify the error on the transformer and to select the most appropriate method.

Abstract

Growing technology increasingly developed software for computers such as mission planner. Mission planner serves to control the remote control from a distance with telemetry and GPS support which became the background for using the graphical interface (GUI) so that it can describe the mapping of the existence of the position of the ship and the depth who has skipped the tool. However, the graphical interface (GUI) is not able to display maps offline because it requires large storage. Meanwhile, for simulations uses the survey ship on autopilot (without a crew) that are connected to the graphical interface, in which the data will be processed and produced a mapping in the form of 3D graphics or according to the order that has been created previously. The hypothesis of this research is the GUI can display charts the contours of the land that could indicate the depth of the river and use the original folder is taken directly from the Google online.

Abstract

The low learning outcomes have a negative impact on the quality of graduates. This study is aimed at revealing the effect of multimedia exploratory tutorial model on the learning outcomes of Basic Competence (BC) and Advanced Competency (AC) based on the students’ visual ability differences in the course of Transformator. The research was conducted in State University of Medan using quasy experiment. Samples of 82 students were divided into three groups: Visual High (VH), Visual Medium (VM) and Visual Low (VL). The comparison of research results was analyzed by Anova. The result shows that at the BC level the students learning outcomes in the VM and VH groups were higher than VL while the VM and VH did not differ significantly. At the AC level the three student groups differ significantly, the VH group is higher than the VM and the VM is higher than the VL. This study concludes that multimedia exploratory tutorials are effective for VM and VH student groups but not for VL. Therefore exploratory multimedia should be used for VM and VT students to obtain optimal BC and only for VH group to obtain optimal AC. However, this multimedia is not recommended for students with low visual abilities (VL).

Triwiyanto, O. Wahyunggoro, H. A. Nugroho, Herianto

Department of Electromedical Engineering, Health Polytechnic of Surabaya, Ministry of Health, Indonesia


Abstract

Electromyography (EMG) has widely used in the field of biomedical engineering as a control signal for prosthetic devices and robotic exoskeleton. High accuracy in the prediction of the limb joint is very important to determine the effectiveness of the system. In this study, we propose a new algorithm to improve the elbow joint angle prediction based on electromyography using Sign Slope Change (SSC) feature extraction and Kalman filter (SSC-KF). The EMG signal was collected at the biceps muscles. The EMG was extracted using SSC feature to get the prediction of the elbow joint angle. The accuracy of the prediction of the elbow joint angle was improved by using Kalman filter. In this study, the SSC-KF algorithm can predict the elbow joint angle with high accuracy. The Pearson’s correlation coefficients were 0.95±0.02, 0.96±0.01, and 0.96±0.015 for the motion period of 12 seconds, 8 seconds, and 6 seconds, respectively. Root Mean Square Errors were 10.37º±1.72º, 9.89º±1.11º, and 9.99º±2.2º, for the motion periods of 12 seconds, 8 seconds, and 6 seconds respectively. This SSC-KF algorithm can predict the elbow joint prediction by using a single lead electrode from biceps muscle.

Abstract

Nowadays, security issues are an important part of everyday life. A vital link in security chain is the identification of users who will enter the room. This paper describes the prototype of secured room access control system based on face recognition. The system comprises a webcam to detect faces and a solenoid door lock for accessing the room. Every user detected by the webcam will be checked for compatibility with the database in the system. If the user has access rights then the solenoid door lock will open automatically and the user can enter the room. If the system does not recognize the face of the user, then the data will be sent to the master user via Android-based smartphone that installed certain applications. If the user is recognized by the master user, then the solenoid door lock will be opened through the signal sent from the smartphone. However, if the user is not recognized, then the buzzer will alert. The main control circuit on this system is Raspberry pi. The software used is Open CV Library which is useful to display and process the image produced by webcam. In this paper, we employ Haar Cascade Classifier in an image processing of user face to produce the face detection with high accuracy.

Wireless Sensor Network on LPG Gas Leak Detection and Automatic Regulator Breaker System Using Arduino
Laksmita Dewi, Yoyo Somantri

Indonesia University of Education


Abstract

Majority chase of LPG explosion caused by gas leakage that wasn’t detected in the preliminary situation. The detection of LPG in free air has a purpose in order to neutralize and prevent gas leakage spreads out and inflicts explosion. This detection should not only do in just one point because gas can possibly leak at the gas regulator and its hose. Therefore, Wireless Sensor Network (WSN) is one of the methods for detecting gas leakage in more than one point. This paper describes how WSN is being integrated with explosion prevention system. This method is using two or more gas sensors to detect leakage in two or more locations around the gas tube and its distribution line. WSN system work based on TGS 2610 gas sensor and NRF24L01 wireless module. Explosion prevention system work based on alarm/buzzer, exhaust fan, and automatic gas regulator breaker. If gas leak then sensor sending its data wirelessly to Arduino and activate explosion prevention system. Arduino activates the alarm/buzzer, release gas regulator knob automatically, and neutralize the air with the exhaust fan. Both systems will be fully controlled by Arduino platform.

Abstract

Nowadays, nanomagnetic devices have a main role in computer industries. To observe magnetic features of the nanomagnetic device, Magneto-optical effects such as Kerr effect and Faraday effect can be used. We report the fabrication of the Faraday effect measurement setup for characterization of nanomagnetic elements. With achievement of low noise measurement configuration by precision electronic measurements, Faraday effect was observed. The essence of the experiment is to measure a light intensity that is transmitted from the transparent magnetic material. Light intensity is measured by a photodiode detector (Hamamatsu S5870) which produced the laser-induced photocurrent. Using transimpedance amplifier, the signal is converted to the voltage which is measured by the lock in amplifier (Stanford Research SR810). By performing the measurement at different lock-in frequencies and different analyzer angles, we systematically analyzed various random noise sources and their effect to the signal to noise ratio. The change of the Faraday effect is measured with variation of the external magnetic field.

Abstract

A Short-term electrical load prediction can use an artificial neural network approach. In this paper, an optimized neural network, namely Evolving Neural Network (ENN) has been developed for short term electric load prediction. ENN uses a genetic algorithm to optimize the weighting of neural networks. After the feedforward algorithm, the process continues with optimization, instead of learning process normally applied to the neural network. The proposed algorithm is implemented in MatLab. Data from April 2010 to April 2011 will be used as training data and data in May 2011 will be used as checking data. To evaluate the performance of Evolving Neural Network, Wavelet Neural Network (WNN) is also involved for comparison. The evaluation is conducted by observing the prediction results. Performance measurements are performed by observing errors that occur. The smaller the error value, the better the accuracy. The experimental result shows that the accuracy performance of ENN is better than WNN.

Abstract

Natural fiber is one of the potential candidate to be used as a reinforcement biocomposite. In this study, sisal fibers were mixed with Polymethyl Methacrylate (PMMA) with addition of MAPP to improve the compatibility of sisal and PMMA. The biocomposites with fiber loading 30 wt.% and various ratios of MAPP (3 wt.%, 5 wt.% and 10 wt.%) were fabricated by hand lay-up method. Several tests were done to analyze the samples such as tensile test and scanning electron microscopy (SEM) to analyze the bonding between the fibers and the matrix in the biocomposite specimens. Tensile test of biocomposite speciments were conducted according to ASTM D638-01. The results showed that tensile strength of the biocomposite with MAPP ratio of 5% tend to be higher than that of the others with tensile strength of 35,82 MPa. SEM image of fracture surface structure of biocomposites indicates that the addition of MAPP improved the interfacial interaction between sisal fiber and PMMA matrix.

Mahros Darsin

University of Jember


Abstract

In general, the easiness of machining is improved when the material is softer. Three heat treatments were carried out to improve drillability of titanium alloy 6Al-2Sn-4Zr-6Mo in compare to the as received (AR) one. They were heated at 870oC for three hours then followed by air cooling, another was heated at the same temperature but followed by water cooling; the third was heat at 985oC then followed by furnace cooling. They were called as HT1, HT2, and HT3 respectively. The hardness of those four conditions was about the same except for the as HT2 which is a bit softer. Microscope observation revealed that AR, HT1, and HT2 result in elongated “primary” alpha grains in an aged transformed beta matrix containing acicular alpha, though the grain size of them are different. Whereas, the HT3 result in transformed beta with prior beta boundaries. While a thin continuous alpha film is present at the grain boundaries. The forces that work during drilling were evaluated. The as HT3 shown as the lowest thrust force work while the others about the same each other. Observation of the chips shown that most of the chips hardness was increased compared to that of the block before drilling.

Abstract

Reduced graphene oxide (rGO) was synthesized using sonication-assisted oxidation of graphite followed by reduction with ascorbic acid as environmentally friendly reductor. The polyaniline was prepared via chemical polimerization of aniline in 0 oC. The rGO and polyaniline were blend in three mass compotitions of 1:3, 1:1, and 4:1 to produced rGO/polyaniline nanocomposites. The rGO/polyaniline nanocomposites were characterized using Raman spectroscopy, Fourier transform infrared spectroscopy and LCR meter. The rGO sheets as the support materials could provide more active sites for the nucleation of polyaniline, where polyaniline acts as conducting support. The rGO/polyaniline nanocomposites was deposited on synthetic graphite substrate laminated the glass substrate and applied as the counter electrode for efficient dye sensitized solar cells (DSSC). The rGO/polyaniline nanocomposite is an efficient counter electrode because of Pt/TCO free. The usage of rGO/polyaniline nanocomposites film as counter electrode in DSSC was demonstrated. The best performance was obtained for rGO/Polyaniline ratio of 4:1. Here, the optimum short circuit current density (Jsc), the open circuit current (Voc), the fill factor (FF), and the overall conversion efficiency under AM 1.5, 100 mW cm−2 illumination are 7.853 mA/cm2, 0.64 Volt, 47.2% and 2.64%, respectively.

Abstract

The effect of the temperature ranging from cryogenics to room temperature were investigated on the formation of the optically-active point defect called the G-centre. The G-centre as an emissive point defect gained a lot of attention recently due to its sharp zero phonon luminescence peak at a wavelength of 1.28 μm (0.97 eV) with the evidence of lasing occurred in the structure. The emission of the G-centre is attributed to the carbon substitutional–carbon interstitial (CsCi) complex which interacts with silicon interstitials during the damage event. This complex is generated by implantation of carbon and followed by proton irradiation. Prior to the carbon implantation, two of the samples were pre-amorphised by germanium. Photoluminescence (PL) measurements were carried out at temperature ranging from 80 K up to room temperature to observe the intensity of the main peaks. The results confirm that the main peaks of point-defect centre in all of the samples including the G-centre suffer from the temperature quenching. However, the peak intensity for some of the wavelength especially the ones with high FWHM, do perform better at high temperature. The temperature quenching phenomena observed in the point-defect technique is the main problem that needs to be addressed and solved before realizing the method in the all silicon photonic system.

Abstract

The effects of concentration of Sodium Dodecyl Sulfate (C12H25NaSO4) as surfactant on structure and hardness of electrodeposited Ni-TiAlN composite coating has been investigated. The composites were deposited at fixed current of 3 mA, 12 V for 15 minutes. The electrolyte consists of 0.49 mol/l H3BO3, 0.17 M NiCl26H2O, 0.38 M NiSO46H2O , 2 gr/lit AlN and 2 gr/lit TiN. The concentration of Sodium Dodecyl Sulfate (SDS) was varied into 0.2 , 0.4 and 0.6 gr/lit. The electrodes used were Pt wire as counter electrode, silver (Ag) wire as reference electrode and tungsten carbide (WC) rod as working electrode. The surface morphology and composition of composites were characterized by using Scanning Electron Microscopy (SEM) dan Energy Dispersive Spectroscopy (EDS), respectively. The crystal structure of comosites was characterized by using X-Ray Diffraction (XRD) and the hardness was tested by using hardness Vickers tester. The results showed that a fewer aglomeration was formed on the composite surface for SDS concentration of 0.4 gr/lit. However, the increase of SDS concentration lead to the increase of crystal size and hardness of composite.

Mechanical Engineering of Vocational College Universitas Gadjah Mada


Abstract

Grey cast iron had been used as shoe brakes of train due to its low cost and enough strength. The most problems of grey cast iron of the shoe brake were the variation of hardness and wear rate between the surface and inside of the shoe brake. The small wear rate of the shoe brake resulted in the damage of wheel of the train. The amount of graphite and ferrite increased if silicon content was increased. Increasing silicon content resulted in the increasing hardness of ferrite. The hardness of grafit was low but the wear rate was high. On the contrary, the hardness of ferrite was high, but the wear rate was low. The aim of this research was to obtain the data of the appropriate silicon content within grey cast iron of the shoe brake with the result that the wear rate of the shoe brake was high and the variation of the hardness and the wear rate between the surface and inside of the shoe brake was small. Casting process was done in foundry, while the hardness and wear test were done in material laboratory. The addition of silicon was done at the same liquid of grey cast iron, without the addition of the other elements. The data of the composition of the grey cast iron was in carbon equivalent. The research was done at the carbon equivalents of 4.18%, 4.44%, 4.64%, 4.80%, and 4.54%. The largest wear rate and the small variation of the hardness and the wear rate of the shoe brake was when carbon equivalent was 4.64% . The largest wear rate was of 0.00011 mm3/kg.m and the average hardness was of 95.58 BHN.

Abstract

Ultra high molecular weight polyethylene (UHMWPE) is a biomaterial used for the human hip joint prosthesis bearings for decades. The main disadvantage is the wear resistant. The products should be in service in the lifetime of the patients. Tribological assessments by experiments and computations should be made to solve that problem. The aim of this research is to predict the UHMWPE acetabular cup wear volume sliding against commercially pure titanium (cp Ti) femoral head in a hip simulator. The cp Ti has the highest biocompatibility compared with other femoral head metals such as cobalt chrome, titanium alloy and 316L stainless steel. Computation processes use the Abaqus contact mechanics algorithm followed by a custom made Python script for the data extractions and Archard wear model calculations. Models were an assembly of the UHMWPE acetabular cup and 32 mm cp Ti femoral head in a biaxial rocking motion hip simulator. Sliding between the models was a 60 cycles per minute rotation. Calculations conducted for one million cycles cumulative polymer wear volume in five steps of 200,000 cycles. The geometries of the models were updated in every step. Experimental pin on disc tests conducted to obtain the wear factor and coefficient of friction. Those data support the input of computations. Wear volume verification use the experimental data from Röstlund. Results show a numerical error at 31.42 percents.

Shot peening is a mechanical surface treatment that can produce compressive residual stresses caused by plastic deformation on the surface of material. This plastic deformation can improve the surface characteristics of metallic materials, such as modification on surface morphology, surface roughness and surface hardness. Biomaterial of 316L is an austenitic stainless steel that widely used in the medical application as an implant material. The shot peening treatment can improve the surface characteristics of 316L biomaterial. The aim of this study is to investigate the effect of shot peening on surface modification, surface roughness, and surface hardness of 316L biomaterial at different shot distance and shot angle. The shot peening parameters that used in this research are shot distance (6, 8, 10, and 12 centimeters), shot angle (30, 60, and 90 degrees), working pressure (7 bars), shot duration (20 minutes), and using steel balls S-170 (diameter of 0.6 millimeters). The result showed that the shot distance and shot angle of shot peening can improve the surface morphology, surface roughness, and surface hardness of 316L biomaterial at shot distance of 6 centimeters and shot angle of 90 degrees. This phenomenon showed that the shot peening can improve the surface modification, surface roughness, and surface hardness of 316L biomaterial.

Department of Civil and Environment Engineering, Gadjah Mada University of Yogyakarta


Abstract

Mix design of Self Compacting Concrete or SCC is not straight forward because many parameters control its rheological properties. The case becomes more complicated if high compressive strength is also to be achieved. Therefore simpler approach is used, that is by firstly determining the flow mortar mix which is easier to be designed even with the requirement of ultra high compressive strength. The mix design of SCC is then determined by simply adding the coarse aggregate with a certain amount of that mortar mix. In this research the ultra high compressive strength flow mortar was made of Type I cement, 15% of cement weight silica fume, weight ratio of cement and curve No. IV sand was 1: 0.35. The water-cementitious ratio was 0.22 and the amount of plasticizer was 1.3%, 1.4%, 1.5% and 1.6% of the cement weight. For the SCC, the used absolute volume of mortar mix was taken to be 1.4, 1.6, and 1.8 of the volume of that aggregate void where the aggregate size was 4.8 mm - 9.6 mm. Test results show that the mortar flowability was 170 mm, 180 mm, 220 mm and 250 mm, where the achieved compressive strength was 83.1 MPa, 96.8 MPa, 111.4 MPa, and 135.5 MPa respectively. Mortar mix with 1.6% super plasticiser was then used for making the SCC and the results show that the concrete flow were 460 mm, 580 mm and 660 mm and the compressive strength was 88.2 MPa, 100.0 MPa, and 97.9 MPa. It can be concluded that using this simpler approach the SCC can have 580 mm flow and 100 MPa compressive strength.

Abstract

Measurement of diffusion coefficient by the Wiener method i.e. deflection of the laser beam caused by the refraction of light on the inter-diffusion area of two fluids with refractive index graded, have shown relatively good agreement with literatures in previous studies, especially for liquids of small molecule-sized order of Angstrom and having mass of less than hundreds amu (atomic mass unit). In the present study, the same method used to examine the diffusivity of some abundant available liquid vegetable oil with a size relatively larger molecule in a suitable solvent. Those are palm oil, coconut oil, corn oil, and sunflower oil. Vegetable oil has a structure and composition that is quite complicated and become the raw material of biodiesel as alternative fuels as well as for cooking so challenging to be tested. To improve the sensitivity and simplify the measurement, a modification to the pouring technique and automation of sample retrieval and processing of the image curve pattern of the laser beam refraction results using the camera has been done by image digitizing, as well as the calculation of the diffusion coefficients and the estimated radius of the molecule. From the result, it has been found the good suitability of diffusivity calculations with literature values, so that the measurement system is also accurate enough to observe the diffusion of liquids with relatively large molecules.

Abstract

Fabrication of \(La_{0,9}Ca_{0,1}FeO_{3}\) thick film ceramics using \(Fe_{2}O_{3}\) powder extracted from yarosite mineral as ethanol gas sensor has been successfully performed. \(Fe_{2}O_{3}\) powder extracted from yarosite mineral as the basic material in this research can increase the added value yarosite mineral. \(Fe_{2}O_{3}\) powder and 10% mol of CaO dissolved in HCl were mixed with \(LaCl_{3}.7H_{2}O\) powder dissolved in aquades. The solution of \(Fe_{2}O_{3}\), \(LaCl_{3}.7H_{2}O\) and CaO mixed and then precipitate using \(NH_{4}OH\). The \(La_{0,9}Ca_{0,1}FeO_{3}\) precipitate was calcined at temperature \(800^{0}C\) for 2 hours to produce \(La_{0,9}Ca_{0,1}FeO_{3}\) powder. \(La_{0,9}Ca_{0,1}FeO_{3}\) powder was crushed and mixed with Organic Vehicle to produce a \(La_{0,9}Ca_{0,1}FeO_{3}\) paste. Using the screen printing technique, the \(La_{0,9}Ca_{0,1}FeO_{3}\) paste is coated on the alumina substrate and then burned at \(600^{0}C\) for 2 hours to produce the thick film ceramic \(La_{0,9}Ca_{0,1}FeO_{3}\). Based on XRD and SEM characterization data, the thick film ceramics \(La_{0,9}Ca_{0,1}FeO_{3}\) were made even though some of \(Fe_{2}O_{3}\) did not react and the grain size is almost uniform, and there are many pores. Measurement of electrical characteristics shows a good response to the presence of ethanol gas, has high electrical sensitivity value and low optimum working temperature that is in the range \(290^{0}C-295^{0}C\).

Syukur Pambudi, Affan Hifzhi, Levin Soedarmawan, Arief Sudarmaji, Djati Handoko

Departemen Fisika, Universitas Indonesia, Depok 1424, Indonesia


Abstract

The mass transfer of NaCl aqueous solution in liquid has been systematically investigated by varying the number of NaCl amount and time of observation. The measurement system utilizes deflection of a laser beam while entering interface of liquid-liquid with different refractive index. Interestingly, the deflection beam has been found to be more deflected with an increase of the number of NaCl amount, suggesting that the refractive index gradients are modified. However, the dynamic refractive index gradients are analyzed by observing the deflection beam with respect to time. The deflection beam pattern transforms from deeply curved to flat with a different rate, indicating that mass transfer velocity depends on the number of NaCl amount. The diffusion coefficient of NaCl is found in a good agreement with coefficient values specified in the literature.

Department of Physics, Faculty of Mathematic and Sciences, Universitas Indonesia, Depok 16424


Abstract

Liquid-liquid diffusion with different refractive index measurement system has been carefully constructed by using laser beam deflection method. Refraction has known depend on the molecule characteristics of a material. The deflection which the pattern formed as a gradient come from refraction of the beam when entering the interface of two different refractive index liquid. The diffusion coefficient is determined by observing refractive index gradients of liquid-liquid on the interface. In this phenomenon, mass transfer from denser liquid to another liquid play an important role and described by using the Fick’s Law. The diffusion experiments have been performed with NaCl-Distilled Water solution. Interestingly, we found the diffusion coefficient of NaCl reasonably good agreement with coefficient values specified in the literature. The time dependent observation also discussed to obtain comprehensive behavior of mass transfer phenomenon. By using the diffusion coefficient, we discuss further about molecule radius. With simple setup and data analysis, we believe that the measurement system can be used to observed mass transfer and molecule characteristics in liquid accurately.

Polytechnic Manufacture Astra


Abstract

This research was conducted in Manufacturing Industry in Indonesia. The company, especially at the Plant, does the TPM (Total Productive Maintenance) activity carried out by a small group of various divisions, especially maintenance. Maintenance implements these results into LOR (Line Operation Ratio). LOR standards is set by the company is 85%. So it can be made the target of a higher LOR future. For it must lower the existing downtime. Downtime highest Fin Forming machines are Dandori Models that are equal to 2,608 minutes or about 9:30% of LOR. Standard downtime allowed 5% of LOR. In the process, dandori models required a process of stretching aluminum material manually along with the crank process forming roller. In this process the operator must perform movement to the uncoiler machine to stretch the material and the operator moves to the forming to crank on forming roller, here, there is no time which required operators to perform movements from the uncoiler to forming. We design a special controller to turn on the motor servo feed rollers on the forming machine. The material can move automatically when operators do crank forming roller, and the operator does not need to move to the position of the engine to stall uncoiler material reels manually.

Commonly, research on humanoid robots use static walking and dynamic walking methods for its stability. The usage of static walking methods on robots emphasize on the stability of every pose, while dynamic walking emphasizes on its efficiency in mobility while walking. The combination of both walking methods can achieve a stable and efficient humanoid robot movement, in which applies the rule of Zero Moment Point and Invers Kinematic. Other than that, there are other supporting factors in stability, such as the mechanical design and electrical system which helps the movement of humanoid robots. In this research, we will use inertial measurement unit for supports Zero Moment Point and Invers Kinematic methods with the application of Kalman filter and PD controller on data from inertial measurement unit. PD controller use feedback data from IMU for adjusting the position of servos that was calculated by Zero Moment Point and Invers Kinematic methods when the robot is in a walking state. This research will be done by comparing results from simulation and direct examination of a humanoid robot to get its stability margin and velocity. The result of humanoid robot stability margin is 5.367 mm in X-axis and 10.567 mm in Y-axis, and its minimum velocity 0.0524 m/s and maximum velocity 0.0633 m/s on grass with altitude 3 cm and minimum velocity 0.0933 m/s and maximum velocity 0.1048 m/s on grass with altitude 1.5 cm

Design and Simulation of Washing Machine Drying Motor Control System using Fuzzy Logic Controller (FLC)
Ade Gafar Abdullah, Nur Wulandari

Universitas Pendidikan Indonesia


Abstract

This paper describes about the application of Fuzzy Logic Controller (FLC) and applies weight sensor for designing and simulating the washing machine drying motor control system. The controller can determine the speed of the washing machine drying motor based on the heavy of the clothes to be dried. Weight sensor is applied as a detector of the heavy of clothes to be dried. The use of FLC in the washing machine is caused by the use of 1-phase induction motor which is less stable with the change of load received. Motor speed is affected by the input voltage. When the load is small, it produces a large input voltage and makes the motor speed fast. Meanwhile, if the load is large, it produces the small input voltage and the motor speed will be slow. In this paper, the washing machine drying motor control system is designed and simulated based on the theories of Fuzzy Logic in MATLAB software.

Abstract

All people have their own goals and motivations in doing sports activities. Some of them do it because of a healthy lifestyle, while others have a desire to form an ideal body. Basically, exercise is a part of daily life. However, the health of the body can be affected by other post-exercise activities such as food intake. After doing exercise, they should consume foods containing good nutrition as a substitute for the nutrients used during exercise. Due to the importance of knowing the use of calories during exercise, it is necessary for humans to have a tool which is able check it without having to go to the hospital or doctor in the first place. In this paper, we develop an application that can be used to check out the best nutrition after exercise. This app has a list of food databases with nutritional calories per portion. The application combines the results of processed sensors in calories.

UNIVERSITAS PENDIDIKAN INDONESIA


Abstract

Indonesia is an agrarian country, populated by approximately 260 million people. According to Pusat Statistik Indonesia, 97.29% of the population consume vegetables. Thus, there is a large demand for vegetables in Indonesia. The vegetables are sold in several places, such as supermarket, traditional market, or even directly from the farmer, with a varied price. Indonesians tend to be price-conscious when it comes to choosing vegetables; however, cheaper vegetables are not known for its safety. Cheaper vegetables are often contaminated by hazardous substances, such as pesticides. Those substances could hinder growth in children, and/or become carcinogenic and trigger the mutation of healthy cells to cancerous cells when ingested by the endocrines. To avoid those substances, people are advised to plant their own vegetables, especially if they live in the city, Where the source of affordable and healthy vegetables hard to get. With IoT, it is expected that the process of planting and monitoring vegetables could become easier. The tools used in this project are cameras, ESP 32 microcontrollers, and supporting sensors (such as humidity and temperature sensor).

Abstract

The efficiency of the generator engine is very influential on the performance of the entire steam generating system, the efficiency is proportional to the performance of the generator engine. Efficiency also depends on the working age of the machine, therefore an analysis of the efficiency of generator engines based on a certain period of time is needed. One way to find out the feasibility of a generator is by calculating the efficiency value of the generator now (actual) compared to the efficiency value of the generator at the first time the generator is operated (commissioning). Manual calculations in analyzing efficiency are quite complicated because they are concerned with steam (thermodynamic). To facilitate the calculation of the analysis required mathematical support software. This research is focused on making simulation for efficiency value based on certain time period according to operational age of generator using MatLab software with aim of more variation result and can be presented in the form of graph is easy to understood. This result can also be made as a prediction of the feasibility of a steam generator engine. This research was conducted PLTP Kamojang, West Java, Indonesia.

Wireless Sensor Network on LPG Gas Leak Detection and Automatic Gas Regulator System Using Arduino
Laksmita Dewi, Yoyo Somantri

Universitas Pendidikan Indonesia


Abstract

Most of LPG explosions are caused by undetected gas leakage in the pre-leakage condition. So that, LPG detection system is needed. The purpose of this system is to detect gas leakage, neutralize it, and prevent the explosion. Gas leakage could happen due to improper regulator installation or the broken hose. This detection should not work in just one location because gas can leak at the gas regulator and its hose. Therefore, Wireless Sensor Network (WSN) is one of the methods that suitable for detecting gas leakage in the wider area. This method uses two or more gas sensors to detect leakage in two or more locations around the gas tube and its distribution line. WSN system works based on gas sensor MQ-6 and wireless module NRF24L01. Explosion prevention system works based on alarm/buzzer, exhaust fan, and automatic gas regulator. If the gas leaks, the sensor will send its data wirelessly to Arduino. Then, explosion prevention system will be activated. The system will turn the alarm/buzzer on, automatically releases gas regulator, and neutralizes the air with the exhaust fan. Both systems will be fully controlled by Arduino platform.

Hilman Aditia Setiawan, I Wayan Ratnata, Bambang Trisno

Universitas Pendidikan Indonesia


Abstract

Power factor optimization is a way of saving and improving the reliability of power systems in industries that mostly use induction motors as low-power operation equipment. This study aims to analyze the size of the capacitor bank needed to improve the power factor in the industry using inductive loads so that the industry can use the power factor with the optimal value (PF≈1). The magnitude of the capacitor bank used to improve the power factor in the industry is divided into several steps. This is done because the amount of power consumed loads vary at any time. There needs to be a control to adjust between the use of load power with step capacitors installed so that load power factor is not too laging or too leading. In this study, the controls used by the author to overcome the above problems using Reactive Power Regulator control.

Abstract

Microstrip line has become the most utilized transmission line for microwave circuits, but it has unbalanced characteristic, while coplanar stripline is a popular balanced transmission line for designing balanced circuits. Most of the ultrawideband antenna is a balanced antenna type such as dipole, bow tie, or two arms antenna. Therefore, we need a transition structure to feed a balanced antenna because the port is usually an unbalanced structure like an sma connector. In this paper, a microstrip to coplanar stripline transition design is proposed. The goal is to make a compact and low-cost transition line that works at 2-18 GHz band for the ease of use with balanced antenna. To achieve the goal, this transition line has been simulated and optimized to find the most appropriate design with FR4 as the substrate. Simulation result show the return loss are better than 10dB for 2-18 GHz but it has insertion loss higher than 3dB in frequencies above 8 GHz due to the FR4 characteristic.

Andra Yovinda;Dadang Lukman Hakim

Universitas Pendidikan Indonesia


Abstract

Energy demand in Java continues to grow every year. To prevent energy crisis in Java, the transmission of High Voltage Direct Current (HVDC) of Java-Sumatra interconnection is a concrete solution. The complete HVDC system always includes at least one converter operating as a rectifier (converting AC to DC) and at least one operating as an inverter (converting DC to AC). Modular multilevel converter (MMC) is one of the most promising topologies for high-voltage and high-power applications. The advantages of MMC exist in the modularity . MMC are built by identical submodules that are connected in series, but can be individually controlled. therefore, the losses of the HVDC transmission line are very small.

Abstract

In electric power system operations, most of the costs incurred are for fuel at the plant. Fuel consumption will be greater following the greater of power generation output so the cost of power generation will increase. But the power generation can change according to demand, meaning the generator output is always strived to match the needs on the load side. To minimize generating costs, an Economic Dispatch analysis is required by dividing the load on each generating unit based on the Heat Rate. Loading optimization aims to obtain economical operating costs with due regard to the constraints of the capacity of the generating unit itself. The method used in this final project is Lagrange Mulptiplier and Particle Swarm Optimization (PSO) method. The main advantages of the PSO algorithm is that it has a simple concept, easy to implement, and efficient in computation compared to mathematical algorithms and other heuristic optimization techniques. To see the level of accuracy and optimization results that have an economic price, the simulation results with PSO will be compared with the conventional method of Lagrange Mulptiplier.

Fahmi Nur Husna

Universitas Pendidikan Indonesia


Abstract

In the system of electrical power plants, the output of the power plants must be able to provide good reliability for the customer. It means that the magnitude and frequency must be able to maintain within standard of tolerance allowed. In this research we try to observe the frequency control during loading or short-circuit in power system. Implementation is modeling the power plants and automatic frequency control in MATLAB. At the time of adding the load, the system have a drop voltage for a moment when the load is connected to the system, but this state very quickly recovered to normal condition due to frequency control installed and work automatically. So, we want to make sure that the automatic frequency control is working by keeping the frequency output of the power plant within the standard tolerance allowed.

Abstract

Electric railway is one of mass transportation that is widely used today, especially in urban areas. Electric railway require a continuous power supply and the reliability, therefore protection system should be very good in order to secure the equipment. The most common disruption to electric railway is the short-circuit caused by insulator damage, one of the ways of protection when an interruption is to enable the relay as the ultimate safety and backup, but not all relays can be used in the electric rail transport system, because the signal unsuitable processing for high speed. In order for relays to be used in electric railway systems fuzzy logic rules are used because it has the advantage of rapid response and improves accuracy. This paper will analyze the protection system of railway equipment by applying the fuzzy logic method and simulated in work situation to improve the quality of railway protection system.
