Abstract

Kebutuhan akan sistem penerangan jalan yang efisien dan ramah lingkungan mendorong pemanfaatan energi terbarukan seperti tenaga surya. Penelitian ini bertujuan untuk merancang dan membangun sistem Penerangan Jalan Umum Tenaga Surya (PJUTS) berbasis LoRa yang mampu melakukan monitoring kondisi sistem serta mengatur pencahayaan lampu secara otomatis. Sistem ini terdiri dari panel surya 50 Wp, baterai 12V 35Ah, mikrokontroler STM32, sensor LDR dan PIR, sensor arus dan tegangan (ACS712, dan INA219) inverter, relay, dan modul komunikasi LoRa. Sistem dirancang agar lampu menyala secara otomatis saat malam hari berdasarkan pembacaan sensor LDR, dan berubah dari mode redup ke terang saat sensor PIR mendeteksi gerakan. Selain itu, data sistem seperti tegangan, arus, dan status sensor dikirim melalui LoRa untuk kebutuhan monitoring jarak jauh. Penelitian ini dilaksanakan di TPU Kampung Cilungup, yang memiliki intensitas cahaya matahari cukup dan aktivitas warga hingga malam hari. Hasil pengujian menunjukkan bahwa sistem bekerja dengan baik, dengan tegangan baterai stabil antara 12–13.6 V, komunikasi LoRa berjalan dengan delay rata-rata 0.9–1.4 detik, serta sensor responsif dengan baik sesuai kondisi lingkungan. Sistem ini terbukti efektif sebagai solusi penerangan hemat energi yang dapat diterapkan di area publik seperti taman pemakaman umum untuk meningkatkan efisiensi, keamanan, dan kenyamanan lingkungan ***** The demand for efficient and environmentally friendly street lighting systems encourages the use of renewable energy such as solar power. This study aims to design and develop a Solar-Powered Public Street Lighting (PJUTS) system based on LoRa technology, which is capable of monitoring system conditions and automatically controlling lighting. The system consists of a 50 Wp solar panel, a 12V 35Ah battery, an STM32 microcontroller, LDR and PIR sensors, current and voltage sensors (ACS712 and INA219), an inverter, relay, and LoRa communication modules. The system is designed to automatically turn on the light at night based on the LDR sensor readings, and switch from dim to bright mode when the PIR sensor detects motion. In addition, data such as voltage, current, and sensor status are transmitted via LoRa for remote monitoring purposes. This research was conducted at TPU Kampung Cilungup, which provides sufficient sunlight exposure and frequent community activity at night. The test results show that the system performs well, with battery voltage remaining stable between 12–13.6 V, LoRa communication operating with an average delay of 0.9–1.4 seconds, and sensors responding accurately to environmental conditions. This system proves to be an effective energy-saving lighting solution that can be applied in public areas such as cemeteries to enhance efficiency, safety, and environmental comfort
