IoT (Internet of Things) in smart street lights widely uses Hypertext Transfer Protocol (HTTP) as data exchange between sensors and actuators. This protocol has a weakness in the data exchange mechanism that requires the highest energy usage, reducing the device's service life. Long Range Wide Area Network Protocol (LoRaWAN) offers a more efficient data transfer mechanism for wide area coverage, end-to-end security, and two-way communication. Implementing LoRaWAN in smart street lights can save energy consumption and speed up response time. In this research, we design a prototype for data transfer efficiency in smart street lights using LoRaWAN protocol to perform remote monitoring and control. The system will display the energy usage monitoring of smart street lights and has functionality for turning on/ off the light. The experiment also conducts the response time performance using JMeter. The test results show that the proposed system has better quality data transmission 6.3 times or 8.07 dB at a distance of 1,220 meters, and the success ratio is 100%. The response time reaches 48 ms with 100 users.
