Abstract

Jember Lor Village, particularly RW 10 RT 02 in Patrang District, Jember Regency, is frequently affected by flooding caused by the overflow of the Bedadung River during high-intensity rainfall, while the absence of a real-time early warning system leaves residents with very limited evacuation time. This community service program aims to improve residents' understanding of and preparedness for flood disasters and to introduce an SMS notification-based flood early detection system. The system consists of a float sensor for measuring water levels, an Arduino Nano microcontroller as the data processing unit, and a SIM800L GSM module as the SMS gateway. The program was implemented using a participatory approach through counseling sessions, interactive discussions, and hands-on implementation of the system's components and working principles. The effectiveness was measured using pre-test and post-test instruments and a participant satisfaction questionnaire. The results showed that participants' average scores increased from 54.5 to 87.9, a rise of 61.3 percent, with an overall satisfaction index of 85 percent (very satisfied category). The program is expected to encourage the establishment of a community-based flood preparedness team and the sustainable installation of an early warning system in the area.
