The induction motor is one of the most important parts in the industrial world today, so if an induction motor is damaged it can affect the production process. Therefore, disturbances that exist in induction motors must be predicted or detected as early as possible. One of the causes of bearing damage is lack of lubrication which can cause an increase in motor temperature, noise, vibration and sparks which can cause damage to other parts of the induction motor. So the authors will conduct research using four different parameters namely starting current, vibration, and temperature on Air Compressor motors whose maintenance treatment in re-lubrication is carried out differently. In this study it was found that if the lubrication on the bearings is not maintained properly then the vibration value is very high at 23 to 24 mm/s, the starting current itself increases up to 8 times the nominal current where this can cause large voltage losses, the current is above the nominal current of the motor, which is 133% of the nominal current, with dry lubrication on the bearings of the induction motor, friction cannot be minimized so that the temperature of the motor increases where data is obtained on the temperature rise of the induction motor for 5 minutes the motor works at 74.3⁰ C and this can endanger the induction motor itself, it can be concluded that the lack of lubrication on induction motor bearings affects 4 parameters mentioned before.

Abstract Solar power plant is one of the developments in the use of renewable energy that has received government support through Ministerial Regulation No.49 of 2018 and Ministerial Regulation No.26 of 2021 regarding rooftop solar power plant. Based on the 2019 solar power plant roadmap draft, the investment cost of rooftop solar power plant per kWp is around 14-25 million rupiah, the amount of this investment is an important consideration for the community to install rooftop solar power plant. One alternative to reduce the investment cost of rooftop solar power plant is to reduce the capacity of the inverter by using lighting from DC lamps. This research was conducted by comparing the efficiency values and investment costs, and using the benefit-cost analysis method to compare a series of relevant costs and benefits between the use of DC lamps and AC lamps for household lighting using PLTS. The results of this research is that DC lamps have a light current of 280 – 350 lumens, an illumination intensity of 48 lux, and a PLTS system efficiency of 98,5% which is higher in value compared to AC lamps which have a light current of 250 lumens, an illumination intensity of 21 lux, and a PLTS system efficiency of 49,3% with the same lamp power of 3W. Analysis of the investment feasibility of on-grid and off-grid PLTS, both 2200VA and 900VA shows that the NPV is negative and the BCR value is less than 1, so the investment is not yet feasible.

Switching inverter technology for converting DC to AC using Insulated Gate Bipolar Transistors (IGBTs) has been implemented in the propulsion system of the Jakarta Metro. However, with advancements in power electronics, a newer technology—Silicon Carbide (SiC)—has emerged, offering the potential to reduce switching power losses by up to 30%. The effectiveness of this technology can be evaluated through simulations using MATLAB Simulink, enabling an assessment of its potential application in the Jakarta Metro system. By quantifying this efficiency gain, informed strategic decisions can be made regarding the adoption of SiC technology for DC to AC conversion, whether through the replacement of existing IGBT-based inverters or during the procurement of rolling stock for future phases. The evaluation will be conducted by simulating both existing IGBT parameters and proposed SiC device parameters under current traction motor operating conditions. This simulation aims to determine the output power required to drive the traction motor while maintaining alignment with the current train configuration. A comparative analysis of efficiency between the two technologies will form the basis of this thesis, providing insights into the feasibility and benefits of transitioning to SiC-based inverters for the Jakarta Metro.

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.

Electric bicycles are designed to use renewable energy to support the government's efforts to reduce carbon emission consumption. Problems in every region or city regarding fueled vehicles certainly increase air pollution. Generally, electric bicycles are designed to be a solution and are used in daily life to carry out daily activities by requiring a bicycle gas throttle control that can assist the driver or person in controlling the speed of the electric bicycle. In this study, designing a solar electric bicycle as environmentally friendly energy based on PWM signals to determine the duty cycle value or duty cycle with an optimized PWM value can affect the speed system (km / h) in Revolutions Per Minute (RPM) to determine the performance of the DC motor. The electric bicycle uses 30Wp solar power, two 12V 7.5 Ah batteries assembled in series, and a 24V 250W DC brushless motor. Based on the design results with a total weight of 37kg electric bicycle plus the weight of 55kg, 65kg, 75kg, and 85kg driver variations, the total controller power value is 163.44 watts. The results of duty cycle testing (duty cycle) were 25%, 50%, 75%, and 98%, with 249.9 as the maximum value of PWM and 9.8 Vout generated against the maximum speed of the electric bicycle of 2648 RPM or the equivalent of an electric bicycle speed of 18-28 km/hour. In this case, the electric bicycle is in a condition suitable for use to carry out daily activities by utilizing clean, cheap and appropriate energy

Energi listrik merupakan kebutuhan primer yang vital dalam kehidupan sehari-hari. Salah satu penggunaannya adalah untuk penerangan listrik, yang saat ini umumnya masih menggunakan sistem manual. Penerangan yang dinyalakan dan dimatikan secara manual oleh manusia berpotensi menimbulkan pemborosan listrik akibat kelalaian, dimana lampu sering kali dibiarkan menyala meski tidak ada aktivitas. Solusi dari permasalahan ini adalah sistem penerangan otomatis atau smart lighting. Penerapan smart lighting harus disesuaikan dengan kondisi ruangan; ruangan outdoor dan indoor memiliki pemicu nyala atau mati lampu yang berbeda. Dalam penelitian ini, dirancang dan dibuat prototipe smart lighting untuk kawasan perumahan di Bekasi, Indonesia. Sistem ini menggunakan kombinasi sensor cahaya untuk area outdoor dan sensor gerak untuk area indoor. Hal baru yang diusulkan adalah penggunaan kombinasi sensor cahaya dan sensor gerak untuk ruangan yang juga memanfaatkan sinar matahari sebagai sumber penerangan. Hasil pengujian prototipe menunjukkan bahwa lampu dapat dikontrol secara otomatis dengan sensor, sesuai dengan kondisi yang ditentukan.
