Abstract

Penelitian ini menganalisis preventive maintenance pada motor Condensate Extraction Pump (CEP) 10,5 kV Unit 6 di PT. PLN Indonesia Power UBP Suralaya. Tujuannya adalah mengevaluasi kondisi bekerja motor dengan mengukur temperatur belitan, temperatur bearing, dan getaran (vibrasi) sebagai tanda utama kinerjanya. Penelitian dilakukan dengan cara mengamati langsung, wawancara oleh teknisi, membaca buku referensi, serta menganalisis data hasil pengukuran menggunakan alat thermogun dan vibration meter. Hasil menunjukkan temperatur belitan berkisar antara 41°C hingga 52°C (batas maksimum 110°C), temperatur bearing berkisar antara 38°C hingga 53°C (batas maksimum 90°C), dan getaran (vibrasi) berkisar antara 0,35 hingga 0,60 mm/s, yang jauh di bawah ambang batas maksimum 2,8 mm/s sesuai SNI ISO 10816-3:2011. Persentase error untuk ketiga parameter tersebut berada di bawah 4%, yang menunjukkan motor bekerja dalam kondisi stabil dan efisien. Dengan demikian, penerapan preventive maintenance terbukti efektif dalam menjaga kinerja sistem dan memperpanjang masa pakai motor.

Abstract

This study analyzes the performance of three types of controllers—PID, Fuzzy-PID, and Model Predictive Control (MPC)—in maintaining water level stability in a dam system. Proper water level regulation is essential to prevent flooding, ensure adequate water distribution, and maintain the structural safety of the dam. Previous studies have widely implemented PID and Fuzzy-PID controllers; however, MPC offers significant advantages through system prediction and multivariable optimization. This research compares the performance of the three controllers through simulation analysis using a second-order mathematical model. The results indicate that MPC has the potential to deliver a faster settling time and a smaller steady-state error compared to PID and Fuzzy-PID, although it requires higher computational complexity.

Abstract

This study discusses the design and simulation of an automatic lighting system based on a photodiode sensor using an Arduino Uno microcontroller as the main controller. The system is designed to detect changes in ambient light intensity and automatically control the lamp without human intervention. The photodiode sensor is used as a light detector that converts light energy into an analog electrical signal, which is then processed by the Arduino to determine bright or dark conditions. The output from the Arduino subsequently controls a relay module that functions as an electronic switch to connect or disconnect the current to the light bulb. The research method employed is an experimental approach, which includes system planning, hardware design, software programming, simulation using Proteus, and system performance testing. The simulation results indicate that the system operates as expected, where the lamp automatically turns on when the light intensity decreases and turns off when the ambient brightness increases. This system is expected to improve electrical energy efficiency and provide ease of operation for lighting control, particularly in public facilitiesand workplace environments.
