Abstract

Operations in the industry today use induction motors. There are several types of induction motors, one of which is a 3-phase induction motor. In the use of a 3-phase induction motor, there are several problems at the beginning, one of which is that there is a current surge in the starting received by the windings or rotor of a 3-phase induction motor which will cause damage to the motor windings. In previous research, research has been carried out to reduce electric starting spikes in 3 phase motors by lowering the frequency in a study entitled "Adjusting the Speed ​​of a 3 Phase Induction Motor by Changing the Frequency Using the ALTIVAR 12P Inverter" it was found that the frequency of the regulated voltage was low and stable to minimize inrush current in 3-phase motor starting. Therefore, research was conducted on a system that can reduce these problems, namely the use of a star-delta system on a 3-phase motor to reduce electrical starting spikes in a 3-phase motor. In this study, the electric current value was 0.59 A, the star-circuit voltage value was 219.65 V, and the short-circuit current value was 1.01 A.

Abstract

Abstract  Electrical energy is a necessity that is needed by everyone. To ensure the reliability of electrical energy, the electrical equipment used must be regularly maintained. One of the maintenance carried out is testing the SF6 gas on the power breaker (PMT). This test is carried out to determine the quality of SF6 gas which functions as an insulation medium for PMT. Because when there is a fault current or a normal current at the time the PMT is cut off, an arc will arise which can damage the PMT equipment itself. Therefore, the quality of SF6 gas in PMT must be maintained under normal conditions. In the SF6 gas test, the SF6 Multi Analyzer test tool is used which functions to ensure that the quality of the SF6 gas at PMT is still in good condition. In routine maintenance activities, SF6 gas testing is carried out at 66 kV PMT which is in the 4R2 Reactor Bay. From the test results, the gas purity value of SF6 is 99.9%, the product decomposition or SO2 content of SF6 gas is 26 ppmv, the dew point value is -21.2 ºC, and the pressure value is 0.735 MPa. Based on the test results, there is an anomaly in PMT, namely the results of the SO2 content test in SF6 gas are not normal. The SO2 value exceeds the predetermined standard limit, which exceeds the maximum limit of 12 ppmv. Therefore, in accordance with the analysis of the FMEA method, that is, if there is a bad quality test result for SF6 gas, then SF6 gas replacement and SF6 gas purity testing must be carried out so that there is no widespread disturbance and to ensure the reliability of the electric power distribution system. After replacing SF6 gas, the test results show the value of SO2 = 0 ppmv.

Abstract

Epilepsy is a disease caused by chronic neurological disorders which is characterized by recurrent seizures. Many studies have been conducted to try to cure the disease. In fact, medically, epilepsy cannot be cured, but the frequency of seizures can be reduced by taking medicines regularly. Medicines certainly contain chemicals that have negative side effects on the human body. A solution is needed to reduce the long-term effects caused by medicines that reduce the frequency of epileptic seizures. The research entitled "Designing Internet Of Things-Based Instrumentation System On Seizure Detection Equipment For People With Epilepsy" has the goal of developing a tool for detecting seizures in people with epilepsy that can be monitored remotely by the family. The tool is built using several main components, namely the EEG sensor system, Light Dependent Resistor (LDR) sensor, SW-520D sensor or tilt detector, and GPS Ublox Neo-6M. Experiments have been carried out for each component and the result is that the EEG sensor system after being amplified by 4213 times is 230 mV in relaxed conditions, 121 mV in listening to music, 83 mV in thinking conditions, and 72 mV in sports conditions. The LDR sensor as a light intensity detector has an accuracy rate of 71.12%, the SW-520D sensor or tilt detector as a patient fall detector has an accuracy of 96.7%, and the Ublox Neo-6M GPS as a location detector has an average difference in distance from Smartphone GPS of 2.90 meters.

Abstract

The Solar Power Plant is an environmentally friendly, and Indonesia is a tropical country that gets an average of 4.8 kWh of solar light per day. However, in general, the type of solar panel installation is carried out regularly (statistically) at a certain angle so that the solar radiation absorbed by the solar panels is not optimal when the sun turns its back on the solar panel. This study aims to design a site that can optimally absorb sunlight rays using the Tracking Dual Axis Technology method based on the ATmega 2560 microcontroller as a system controller and Light Dependent Resistor (LDR) as a sun tracking sensor. So that it can maximize the absorption of solar radiation by solar panels. The Dual Axis Technology Tracking testers get a maximum Photovoltac voltage of 20.99 volts and a minimum of 19.75 volts and a maximum current of 21.04 mA and a minimum of 14.12 mA.

Abstract

Permintaan energi listrik di Indonesia terus meningkat, terutama di wilayah pedesaan yang masih menghadapi keterbatasan akses terhadap jaringan listrik nasional. Salah satu solusi yang menjanjikan adalah penerapan Pembangkit Listrik Tenaga Surya (PLTS) off-grid skala rumah tangga. Penelitian ini bertujuan untuk merancang dan menganalisis sistem PLTS off-grid di Kabupaten Karawang dengan menggunakan perangkat lunak Homer Pro, berdasarkan parameter teknis dan ekonomi. Simulasi dilakukan untuk menentukan konfigurasi sistem yang optimal dalam memenuhi kebutuhan listrik rumah tangga sebesar 4,27 kWh per hari atau 1.562,82 kWh per tahun. Hasil menunjukkan bahwa sistem PLTS dengan kapasitas panel surya 8,2 kW mampu menghasilkan 12.570 kWh per tahun, dengan LCOE sebesar Rp 1,83/kWh, yang lebih ekonomis dibandingkan tarif listrik konvensional. Sistem ini dilengkapi dengan baterai lead-acid berkapasitas 8,01 kWh, dengan efisiensi penyimpanan energi mencapai 80,2% dan masa pakai sekitar 7,5 tahun. Dengan kelebihan produksi listrik sebesar 85,4%, sistem PLTS off-grid ini terbukti layak secara teknis dan ekonomis untuk diimplementasikan pada rumah tangga di daerah yang belum sepenuhnya terlayani oleh jaringan listrik.
