Abstract

Perkembangan dalam teknologi kendaraan bermotor mendorong sejumlah upaya untuk meningkatkan kinerja mesin motor, salah satunya dengan menggunakan piston lebih besar. Penelitian ini bertujuan untuk mengevaluasi dampak penggantian piston standar dengan piston oversize 100 terhadap kinerja mesin pada sepeda motor matic Honda Vario 150 cc. Parameter yang diamati mencakup tenaga, torsi, efisiensi bahan bakar, dan suhu kerja mesin. Metode yang digunakan dalam penelitian ini adalah eksperimen, dengan membandingkan kinerja mesin dalam dua kondisi: penggunaan piston standar dan piston oversize 100. Pengujian dilakukan dengan memakai dynamometer pada keadaan operasi yang serupa untuk mendapatkan data yang akurat dan dapat dianalisis. Temuan penelitian menunjukkan bahwa penerapan piston oversize dapat meningkatkan tenaga dan torsi mesin jika dibandingkan dengan piston standar. Namun, terdapat juga perubahan dalam efisiensi bahan bakar dan suhu kerja mesin. Dengan demikian, penerapan piston oversize dapat memperbaiki kinerja mesin, tetapi juga memerlukan pemeliharaan dan penyesuaian operasional yang tepat.

Abstract

Electricity is a very important energy to meet human needs in various fields. Steam Power Plants (PLTU) play a crucial role in producing electrical energy, by converting chemical energy from coal into electrical energy. This conversion stage goes through three stages: conversion of chemical energy into heat energy, heat energy into mechanical energy, and finally into electrical energy. This research focuses on PT. PLN NUSANTARA UP PAITON, one of the largest PLTUs in Indonesia, located in Probolinggo with a total capacity of 2 x 400 MW. The research method used is utilizing literature studies as a source of information, data collection techniques through observation and interviews with related parties. The results of the study show that the Primary Air Fan (PA Fan) has an important role in the combustion process in the boiler, including drying coal powder and regulating air flow to the pulverizer. In its working process, the primary air fan has a protection system to protect the PAF when a disturbance occurs, there are nine protections owned by the primary air fan. In addition, a protection system encompassing various instruments, such as thermocouple sensors and vibration sensors, is implemented to ensure the safety and operational efficiency of the PAF. These include thermocouple sensors, RTD sensors, and vibration sensors.
