Abstract

Penelitian ini membahas perancangan, pembuatan, dan pengujian safety relay module pada sistem kendali internal combustion engine Mitsubishi S4S berbasis Arduino Nano. Latar belakang penelitian berangkat dari keterbatasan sistem kendali asli mesin S4S-DT yang tidak dilengkapi dengan tombol emergency stop serta indikator penyebab shutdown, padahal keduanya merupakan fasilitas wajib dalam standar keselamatan industri. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan pendekatan eksperimental. Proses meliputi identifikasi masalah, studi literatur, perancangan sistem, pembuatan purwarupa, hingga pengujian dalam kondisi simulasi fault. Hasil pengujian menunjukkan bahwa safety relay module yang dirancang mampu bekerja sesuai fungsi utamanya dalam mengendalikan mesin pada kondisi off, on, running, fault, dan emergency. Modul ini dapat memverifikasi syarat start-up, memantau parameter penting seperti kondisi low oil pressure dan high coolant temperature, serta secara otomatis memutus mesin jika terdeteksi fault condition. Tambahan fitur berupa lampu indikator memudahkan operator dalam mengidentifikasi kondisi mesin. Kesimpulannya, sistem safety relay ini dapat meningkatkan aspek keselamatan operasional mesin Mitsubishi S4S sekaligus memberikan kontribusi nyata dalam penerapan sistem kendali mesin berbasis mikrokontroler yang lebih andal

 

This research focuses on the design, development, and testing of a safety relay module for the Mitsubishi S4S internal combustion engine control system based on Arduino Nano. The study originates from the limitation of the original S4S-DT control panel, which lacks an emergency stop button and fault indicators, both of which are mandatory features under industrial safety standards. The research method applied is Research and Development (R&D) with an experimental approach, consisting of problem identification, literature review, system design, prototype development, and testing under simulated fault conditions. The results reveal that the designed safety relay module functions effectively to control the engine in off, on, running, fault, and emergency states. The module verifies start-up requirements, monitors key parameters such as low oil pressure and high coolant temperature, and automatically shuts down the engine when a fault condition is detected. The additional indicator lamps provide operators with clearer fault identification. In conclusion, the system enhances the operational safety of the Mitsubishi S4S engine and contributes to the development of more reliable microcontroller-based engine control systems
