Abstract

Cisadane River is the largest river whose overflow often causes flooding in several locations in South Tangerang City. One of them is located in Pesona Serpong Housing, Setu District, South Tangerang City. The Cisadane Environmental Echo Community (GEMALA) is a community that cares about the sustainability of the Cisadane River. This community service aims to improve understanding of river maintenance and socialize the IoT-based Early Warning System (EWS) tool to the GEMALA community as an early flood detection tool. The method used is to use an ultrasonic sensor HC-SR04 which will measure the water level of the river and will send a signal via the Telegram messaging application. At the end of this activity, an IoT-based Early Warning System (EWS) tool was produced that could be utilized by the GEMALA community as an early flood detection tool.

Abstract

Rats pose a significant threat to rice farmers, attacking crops at all stages of growth, including storage, with the most severe damage occurring during the reproductive phase. In Bendung Village, Bendung District, rats have caused substantial losses, including crop failures, particularly due to unpredictable weather conditions. The proposed solution involves creating eco-friendly rodent repellents powered by solar energy. The activities include socialization, device design, technology implementation, and evaluation. Evaluation results indicate that 40% of farmers understand the operation of the rodent repellents using frequency waves, and 60% understand their environmental impact. This program has provided farmers with new knowledge about methods to repel harmful rodents.
