Abstract

Batteries are components that supply, provide and distribute electrical energy in various electronic devices. Still, there are times when the battery must be recharged because the battery has a high energy storage ratio but has limited power. Another component that functions like a battery is a supercapacitor which can store a large charge of energy that can be used to help battery performance. This study aimed to analyze the impact of installing supercapacitors on batteries operating in solar power plants by varying the number of supercapacitors connected to batteries. The methods used in this research are literature study, design method, manufacturing method, testing method, and data analysis method. Based on the test results, it was found that the installation of 4 capacitors has optimal performance, with an average current consumption of 0.18877551 Ampere. For three capacitors, the average current is 0.203552632 Ampere. For two capacitors, the average current is 0.205517241 Ampere. As for the power characteristics, for four capacitors, the average power is 31.81632653 watts. With three capacitors, the average power is 34.36447368 Watt, and with two capacitors, 34.71724138 Watt.

Abstract

Solar Home System is one of the technologies for utilizing solar power at home. To optimize the performance of PLTS, it is necessary to regulate the use of electrical energy. In this research, an effort is made to control the load using fuzzy logic to regulate the power consumption used by the load so that energy can be utilized effectively. The fuzzy logic method works based on the input given so that the desired results can be as expected. To test the effectiveness of the fuzzy logic method, this study was tested with two types of loads: lighting and fan loads. For lighting loads, it uses two light sensor inputs, and for air conditioning, it uses two temperature sensor inputs and a PIR sensor. The test results show that in the experiment of setting the light load using fuzzy logic, the average power usage at the load is 11.31 watts. In contrast, without fuzzy logic, the average power usage value for the load is 14.29 watts. In the fan load control experiment using fuzzy logic, the energy consumption setting was obtained according to the room temperature input and the number of people in the room. The test results received power usage without using fuzzy logic, where the average fan power usage value is 4.32 Watts, while without fuzzy logic, the average power usage value is 2.97 Watts. For one sensor input, the average power usage value of the average fan is 3.02 Watts; without fuzzy logic, the average power usage value is 2.93 Watts for two sensor inputs.

Abstract

Drainage pit merupakan komponen penting pada Pembangkit Listrik Tenaga Air (PLTA) untuk menampung kebocoran dari berbagai komponen, seperti turbin. Karena banyaknya komponen yang berpotensi bocor, drainage pit sangat diperlukan untuk menampung air yang bocor dari sistem lainnya. Tujuan dari proyek akhir ini adalah untuk mempermudah pemantauan laju aliran serta kebocoran yang terjadi di drainage pit, serta mempermudah pengecekan ketinggian air di reservoir agar tidak terjadi banjir. Metode pembuatan prototipe sistem pompa otomatis berbasis mikrokontroler pada drainage pit melalui beberapa tahapan: (1) merancang prototipe sistem pompa otomatis, (2) merancang sistem kontrol, dan (3) melakukan pengujian. Hasil penelitian menunjukkan bahwa sistem pompa otomatis efektif mengatasi masalah drainase dengan mengoptimalkan penggunaan pompa sesuai dengan ketinggian air dan kebocoran. Berdasarkan hasil pengujian, sistem ini beroperasi otomatis ketika ketinggian air mencapai 35 cm. Pada kebocoran kecil (50% bukaan), hanya satu pompa yang beroperasi. Penggunaan energi terbesar terjadi pada uji kedua selama 175 detik dengan kebocoran 36,29 dan konsumsi energi 0,052, sedangkan penggunaan energi terkecil terjadi pada uji pertama selama 172 detik dengan kebocoran 36,9 dan konsumsi energi 0,0248. Ketika tingkat kebocoran meningkat (100% bukaan), kedua pompa beroperasi secara otomatis. Penggunaan energi terbesar terjadi pada uji ketiga selama 356 detik dengan kebocoran 17,99 dan konsumsi energi 0,0259, sedangkan penggunaan energi terkecil terjadi pada uji kedua selama 349 detik dengan kebocoran 18,25 dan konsumsi energi 0,0255.

Abstract

An overhaul is a process of dismantling a problematic engine so that it can be examined more thoroughly. During the overhaul, the problematic engine components are replaced. The overhaul of the sphere gap setting of the semi-automatic high impulse voltage generation is also intended to maximize the K3 system and the level of accuracy when conducting research on impulse voltage generation. The current condition after the occurrence of damage to the automatic sphere gap adjustment machine. The sphere gap setting is done manually, causing the desired ball gap distance to be not very accurate, and the risk of work accidents is higher in the high voltage laboratory. In the first stage of work, an inspection and measurement were carried out to replace the capacitor and limit switch components because they could no longer be used. As well as improvements to the electromagnetic brake components. From the test results, it was found that the distance measurement was as expected and it can be proven that after an overhaul, the semi-automatic spacer can function normally again so it can make it easier to conduct high voltage impulse research. In addition, from a security point of view, it is better because the spacing between the balls is done outside the high-voltage impulse generation cage

Abstract

On one hand, the particular objective of this research is to yield the software program in order to control efficiently the important aspects in electric power systems which can be implemented in industries. In the other hand, the longterm objective is to extend the curriculum, syllabi, laboratory facilities, and to improve the abilities and qualities of graduates continuously either within State Polytechnic of Ujung Pandang or outside. Method used to achieve these objectives is making, design and implementation which will be last for two years. Simulator for generation system in the first stage of the research is balanced six-phase system yielded from the circuit of 3-one phase centre-tap transformers of 220/18 V, 15 A, as the supply of low-tension 3-phase system, which feeds six one-phase transformer of 18/220 V, 20 A, whose output as another balanced 3-phase system with 220 V/phase. From balanced 6-phase system, a balanced 3-phase will simulate generator number 1 and another balanced 3-phase will simulate that of number 2. Interface which is based on Delphi program is to switch all transmission lines. The result of experiment shows that voltages in the two generator busbars experience the significant drop voltage if they work separately, that are 20.5% - 36.4% and 20.5% - 63.6% for generator number 1 and number 2 respectively, for one to three load busbars operated sequentially, which also reveals that greatest voltage drop occurs in the generator busbar with most lines supplied. Simulating the two generators working simultaneously, then voltage drops are more significant, that are 65.9% - 72.7% and 65.9% - 79.5% for generator number 1 and number 2 respectively, for one to three load busbars operated sequentially, which also proves that transformer bank as generator simulator needs to increase its current capacity.

Abstract

Environmental pollution (pollutants) can be caused by natural events or human care through uncontrolled industrial and technological activities, this can be a threat to living things including humans in the future. This phenomenon is caused by the entry of particles or chemical substances that do not exist in the natural component so that it exceeds the amount that should be. Pollution is the inclusion of substances, energy and aliens into the environment so that the quality of the environment decreases and no longer suitable allocation. Efforts to reduce or control environmental pollution that some environmental scientists and practitioners have done in a better way by the structures produced by various industries and technologies that are seen as backbones. The research installation can provide detailed information about the shape and structure of the current in the pipe (analogized as the exhaust) in the direction and the vertical velocity to air will be inhaled by the fluid of the liquid (air) as motive fluid in the opposite direction. The suction strength of the liquid against the airflow is greatly determined by the vacuum pressure in the chamber because of the effect of the working ejector that is geometrically formed so that the image can be adjusted to that achievement. The parameters used to measure performance in the design of this air-contaminating air-conditioning installation plant are composed of several variables in the ratio of changes between air velocity and liquid flow in opposite directions, vacuum compressions are formed large enough, the fluid flow capacity of the ejector, revascular and the ability to transform gas pollutants into liquid pollutants.
