Abstract

The implementation of an AC Light Dimmer and Relay 2 Channel as an automatic lamp control system on a Street Lighting (APJ) prototype based on the Internet of Things (IoT) is used to support energy efficiency on Jalan Bukit Dharma Raya Jimbaran. This system is designed to automatically adjust light intensity based on time and the presence of road users detected by an ultrasonic sensor. Monitoring and control are performed in real-time via the Telegram platform, with energy consumption monitored using the PZEM-004T module. The prototype is built using an ESP32 microcontroller, which controls the lamp activation, brightness through the AC Light Dimmer, and ON/OFF status via the Relay 2 Channel. Test results show that the system can improve energy efficiency by up to 43.75% and save electricity costs by Rp132.56 during 2 hours of operation. This system implementation has proven to be effective, adaptive to environmental conditions, and supports the application of intelligent and energy-efficient street lighting systems.

Abstract

Street lighting plays a crucial role in supporting public safety and comfort, especially at night. However, many areas, such as Jalan Bukit Dharma Raya Jimbaran, still lack adequate lighting systems. This study designs and implements an intelligent street lighting system based on the Internet of Things (IoT), utilizing the ESP32 Devkit V1 as the central controller, along with an LDR sensor, ultrasonic sensor, and an AC Light Dimmer to automatically adjust light intensity according to time and traffic conditions. Test results show that the system operates efficiently and adaptively, achieving energy savings of up to 17.6% and cost savings of Rp 54.39 compared to a manual system, with efficiency levels varying depending on road user activity. The prototype has proven effective in enhancing energy efficiency and offers an adaptive lighting solution that can be further developed to support the concept of a sustainable smart city.
