Abstract

ABSTRACTMini-generating systems such as PLTS utilize batteries as energy storage media. The increasing use of PLTS also adds to the problem of battery waste (B3). The battery monitoring tool is used to monitor the condition of PLTS batteries and used batteries. This research was conducted using the ADDIE method. Data collection techniques were carried out through literature study, observation, and practice. Research products are battery packs and BMS boxes. The error rate of BMS readings on the values of voltage, current, and temperature are 4.59%, 2.002% and 0.83%. The undervoltage reading error rate is 0.3V. The BMS protection circuit can break the stacking battery circuit when a battery-related problem occurs. The first experiment obtained a measured voltage value of 11.5V when it was not connected to the charging input and the discharging load. The second experiment obtained a measured charging voltage of 12.2V and a measured discharging voltage of 11.9V. Based on these results it can be concluded that the battery is in good condition.ABSTRAKSistem mini pembangkit seperti PLTS memanfaatkan baterai sebagai media penyimpanan energi.

Abstract

ABSTRACTBrushless DC motors or commonly known as BLDC motors are starting to be widely used in the automotive and industrial fields compared to three-phase induction motors. This is because the advantages of BLDC motors are high efficiency, large torque, and easy maintenance. Some drive systems that use BLDC motors require a constant motor speed. However, when the drive system is given more load, the speed will decrease. Therefore, we need a motor speed regulation so that the speed becomes constant even though it is given an overload. There are many ways to adjust the speed of a BLDC motor, one of which is using the Field Oriented Control method because it can adjust the field current and armature current separately. From the simulation results, the speed of the BLDC motor using the FOC method in the loaded condition, showed a better response by producing a steady state of 1494 rpm, a rise time of 0.5192 s, a settling time of 0.6362 s while not being given a load, a steady state of 1504 rpm and, a rise time of 0.533 s and a settling time of 0.64 s.ABSTRAKMotor Brushless DC atau biasa dikenal dengan motor BLDC mulai banyak digunakan pada bidang otomotif dan industri dibandingkan dengan motor induksi tiga fasa. Hal ini disebabkan karena kelebihan dari motor BLDC adalah memiliki efisiensi tinggi, torsi yang besar, dan perawatan mudah. Beberapa sistem penggerak yang menggunakan motor BLDC membutuhkan kecepatan motor yang konstan. Akan tetapi sistem penggerak tersebut ketika diberi beban lebih maka kecepatan akan menurun. Oleh karena itu dibutuhkan suatu pengaturan kecepatan motor agar kecepatan menjadi konstan walaupun diberi beban lebih. Banyak cara untuk mengatur kecepatan motor BLDC salah satunya adalah menggunakan metode Field Oriented Control karena dapat mengatur antara arus medan dan arus jangkar secara terpisah. Dari hasil simulasi didapatkan kecepatan motor BLDC menggunakan metode FOC pada kondisi berbeban, menunjukkan respon yang lebih baik dengan menghasilkan steady state yaitu 1494 rpm, rise time 0.5192 s, settling time 0.6362 s sedangkan tidak diberi beban didapatkan steady state sebesar 1504 rpm dan, rise time sebesar 0,533 s dan settling time sebesar 0,64 s.

Abstract

ABSTRACTFuel Oil (BBM) is one of the fuels that have been used to drive most of vehicles such as motorcycles. The authors did the research on motorcycles using electrical energy to be more environmentally friendly. Experiments were done by using the direct test method and analyzing the obtained data to determine how much power was released and how much battery capacity was used to drive an electric motorcycle with variations of the driver's weight as much 60 Kg, 90 Kg, and 125 Kg and speed variations such as 10 Km/Hour, 20 Km/Hour, 30 Km/Hour, and 38 Km/Hour. The experimental results shows that the greater the weight and the speed of the motorcycle, the greater the power and capacity of the battery, so that could be concluded that the use of the battery on the motorcycle becomes more wasteful and the battery life will be shorter.ABSTRAKBahan Bakar Minyak (BBM) menjadi salah satu bahan bakar yang digunakan untuk menggerakkan kendaraan seperti sepeda motor. Penulis melakukan penelitian pada sepeda motor menggunakan energi listrik agar lebih ramah lingkungan. Dilakukan percobaan dengan metode uji coba langsung dan menganalisis data yang didapat untuk mengetahui seberapa besar daya yang dikeluarkan dan seberapa besar kapasitas baterai yang digunakan untuk menggerakkan sepeda motor listrik dengan variasi berat pengemudi yaitu 60 Kg, 90 Kg, dan 125 Kg dan variasi kecepatan yaitu 10 Km/Jam, 20 Km/Jam, 30 Km/Jam, dan 38 Km/Jam. Hasil percobaan menunjukkan semakin besar berat beban dan kecepatan pada sepeda motor, maka daya dan kapasitas baterai semakin besar dikeluarkan sehingga penggunaan baterai pada sepeda motor menjadi lebih boros dan ketahanan pada baterai semakin sebentar.

Abstract

A milling process utilize DC motors and rectifier circuits. Semiconductor components in the rectifier circuit could cause harmonic distortion. At PT X, the voltage THD generated at the 6KV feeder panel has exceeded the standards set by the IEEE. This study aims to analyze the voltage THD caused by a controlled rectifier circuit and DC motors, and to design a filter to mitigate it. MATLAB software is used to analyze the THD voltage. From the simulation results, it is known that the 400KW, 450KW, and 600KW DC motors produce voltage THD values of 9.35%, 14.23%, and 12.28% respectively which exceed the set standards of 8%. A single-tuned passive filter is designed to reduce the THD voltage value on each motor. The installation of the filter effectively reduces the THD voltage value in the 400KW, 450KW, and 600KW DC motors to 4.34%, 5.38%, and 6.35% respectively.

Abstract

This research shows the effect of oil mixture and temperature on breakdown voltage. Palm oil is combined with diala-b oil in various mix ratios and various temperatures. Test results on the sample, as the concentration of the mixture of diala-b oil increases, the breakdown voltage value also increases. The breakdown voltage values of all oil mixture samples that have gone through the treatment process have met the IEC standard No. 56 of 1991 with results that are classified as above the standard (standard ≥ 30kV/2.5mm). Breakdown voltage values for the composition of 100% diala-b oil, 100% palm oil, and a mixture of 50% diala-b oil: 50% palm oil at 60 °C, 70 °C, 80 °C, 90 °C, and 100 °C is above the standard that is ≥ 30 kV. Water content and acidity affect the breakdown voltage value. Based on the results of breakdown voltage testing that has been done, palm oil can be used as an alternative to transformer oil.
