 1 DECISIONING INFORMATION PRIORITY WITH ANALYTICAL HIERARCHY PROCESS ALGORITHM AND NAÃVE BAYES CLASSIFIERSutadi Triputra, Ririn Suharsih, Aila Gema Safitri, Rinanda Febriani 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 NaÃ¯ve 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.

Topic: Computer Engineering 3 Syllable-based Indonesian Speech RecognitionDanny 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. Topic: Computer Engineering 4 Balanced Sentence Set Based on Syllables and Punctuations using Greedy AlgorithmBagus 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.

Topic: Computer Science and Engineering (E-01) 9 Algorithm to trigger a number of rules based on antecedent lengths as forward chaining engine implementations on any rule-based systemAslan 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. Topic: Computer Science and Engineering (E-01) 10 Simulation studies of Highly Efficient micro-hole textured single crystalline silicon solar cell and effect of varying air mass on it.Sana Zainab (a), Shahzad Hussain (a), Sidra Jabeen (a) (a) National University of Sciences and technology, Islamabad 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.

Yuchintya1, Toha Ardi Nugraha2 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%.

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.

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 studentsâ€™ 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.

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 Pearsonâ€™s correlation coefficients were 0.95Â±0.02, 0.96Â±0.01, and 0.96Â±0.015 for the motion period of 12 seconds, 8 seconds, and 6 seconds, respectively. Root Mean Square Errors were 10.37ÂºÂ±1.72Âº, 9.89ÂºÂ±1.11Âº, and 9.99ÂºÂ±2.2Âº, for the motion periods of 12 seconds, 8 seconds, and 6 seconds respectively.

Topic: Electronics Engineering 73 Wireless Sensor Network on LPG Gas Leak Detection and Automatic Regulator Breaker System Using ArduinoLaksmita Dewi, Yoyo Somantri Indonesia University of Education Abstract Majority chase of LPG explosion caused by gas leakage that wasnâ€™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.

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.

Lingkar Selatan, Kasihan, Bantul, Yogyakarta 55183 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. Topic: Materials Manufacturing and Processing 90 Effect of Heat Treatment Variation in Drillability of Titanium alloy 6246Mahros 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 â€œprimaryâ€ 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.

Advanced Technology Institute, Faculty of Engineering and Physical Sciences, University of Surrey, Guildford, Surrey GU2 7XH, United Kingdom 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 Î¼m (0.97 eV) with the evidence of lasing occurred in the structure. The emission of the G-centre is attributed to the carbon substitutionalâ€“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.

Rawamangun Muka I, Jakarta 13220, Indonesia 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. Topic: Materials Science and Engineering 94 The Effects of Silicon on The Hardness and Wear of Ferritic Grey Cast Iron on Shoe Brake of TrainSuryo Darmo, Lilik Dwi Setyana, Tarmono, Nugroho Santoso 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.

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.

Topic: Materials Science and Engineering (M-02) 101 Refractive index gradients behaviour and diffusion coefficient of NaCl aqueous solution by using optical methodSyukur 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.

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 Fickâ€™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.

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.

Reactive power is a useless power that can not be converted into power but is needed for the process of transmitting electrical energy at the load. So that causes the waste of electrical energy is the amount of equipment that is inductive. Means in using electric energy customer turns out not only burdened by active power (kW) but also reactive power (kVAR). Installation of bank capacitors is one way to solve this problem. The power factor that often arises is lagging. This increase in power factor depends on the value of the installed capacitor bank (kVAR). The method used to solve this problem is Genetic Algorithm (GA). The Genetic Algorithm (GA) method is an algorithm that utilizes a natural selection process known as the evolutionary process. This method is applied to PT real electrical system. NEW with some probable experiments.

Topic: Tugas Akhir (TE-UPI) 176 Power Factor Optimization in Industry Using Bank Capacitors with Reactive Power Regulators ControlHilman 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 (PFâ‰ˆ1). 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.

Topic: Tugas Akhir (TE-UPI) 181 Ultra Wideband 2-18GHz Microstrip to Coplanar Stripline TransitionReynatto Rhieo Anandhitto, Tommi Hariyadi, Mukhidin Telecommunication Engineering Department of Electrical Engineering Education Universitas Pendidikan Indonesia 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 shown the return loss is higher than -10dB for 2-18 GHz but it has insertion loss higher than -3dB in frequencies above 6 GHz due to the FR4 characteristic. Topic: Tugas Akhir (TE-UPI) 182 Design and Implementation of Modular Multilevel Converter (MMC) on HVDC Interconnection Transmission Java-SumatraAndra 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. Topic: Tugas Akhir (TE-UPI) 183 ECONOMIC DISPATCH OPTIMIZATION FOR THERMAL POWER PLANT IN 500 KV JAVA-BALI SYSTEM USING PARTICLE SWARM OPTIMIZATION METHODNuur Miftah Azkiya, Ade Gafar Abdullah, Hasbullah Electrical Engineering Department of Electrical Engineering Education Universitas Pendidikan Indonesia 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.

Topic: Tugas Akhir (TE-UPI) 185 A Simulation Automatic Frequency Control Generator Synchronous in Geothermal Power Plants using MATLAB - SIMULINKFahmi 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.
