RANCANG BANGUN ALAT MONITORING GAS METANA DI AREA COAL BUNKER BATUBARA PLTU ADIPALA

Steam Power Plant use coal as the main fuel for unit operations. The initial stage of the coal transfer process starts from the coal yard to the crusher to be crushed in order to obtain coal with a smaller size. Furthermore, coal will be transferred to the coal bunker before being fed to the mill. Coal enters through the coal feeder inlet before being fed to the mill to be mashed to a certain size. The process of transferring coal from the coal bunker to the mill is carried out continuously according to the needs of the unit. For this reason, the reliability of this system greatly affects the reliability of the unit Coal bunker is a part that is prone to fire or explosion that can occur due to the condition of coal which is prone to burning under certain conditions, so we need a tool that can monitor the condition of coal that is in the coal bunker. Coal bunker are places that are prone to fires or explosions that can occur due to the high conditions of high methane content in the area that can trigger explosions that can occur. In this study the authors aim to design a methane gas monitoring tool in the coal coal bunker area of the Adipala coal plant, as a tool to monitor the condition of the methane gas content in the coal bipers of the Adipala power plant based on a microcontroller. In this study the authors used the waterfall SDLC model research method often also called a linear sequential model or classic life cycle. The waterfall model provides a sequential or sequential software life cycle approach starting from the analysis, design, coding, testing, and support stages. The results of testing on the methane gas monitoring system in the coal bunker coal fired area of the Adipala power plant can run well and are feasible to be implemented as an effort to improve the safety and reliability of the Adipala power plant.
