    Abstract:

    The government’s efforts to maintain national energy stability through programs to increase supply and save energy must be supported by all levels of society, including the upstream side. This study analyzes the potential percentage of electrical energy savings on the upstream side, namely the generation sector. In this study, we will discuss the potential for saving electrical energy own use at PLTP Karaha 1 Pertamina Geothermal Energy located in Tasikmalaya district, West Java. In supporting the operation of PLTP Karaha unit 1, patrol check activities are needed which function to monitor the condition of generating equipment to ensure that the supporting equipment of the generator is in optimal condition. But in fact, when the patrol check activity has been completed, the room lights or indoor lighting are left on for 24 hours continuously due to the engineering design of the lights during the EPC (Engineering Procurement Construction) process. So, a control system is designed to operate indoor lighting automatically using Passive Infra-Red (PIR) sensors and Arduino ATMega 2560 module. Programming on Arduino is done using the Arduino IDE application. In the Arduino IDE application, it shows the library initialization program (sensor) and the initialization of the pins used on the Arduino. The program made on the Arduino IDE application is a program to control the On-Off lights, the LCD display includes the number of people entering the MCC room, the On-Lamp time and the total energy kWh. By using this method, it is hoped that it can be a solution for saving the use of electrical energy for indoor lighting. © 2023 IEEE.
