Abstract

Garlic peel (Allium sativum L.) is a household waste that contains bioactive compounds with potential antibacterial activity. This study aimed to formulate an emulgel containing ethanolic garlic peel extract and evaluate its physical characteristics and antibacterial activity against Staphylococcus aureus and Propionibacterium acnes. The emulgel was evaluated for organoleptic properties, homogeneity, pH, and viscosity. Antibacterial activity was tested using the agar diffusion method. The formulation showed acceptable physical characteristics for topical use. The emulgel inhibited the growth of both bacteria, with inhibition zones of 12.16 mm against S. aureus and 11.02 mm against P. acnes. The antibacterial activity may be related to the presence of flavonoids, saponins, phenolic compounds, and allicin in garlic peel extract. These results suggest that garlic peel extract can be formulated into an emulgel with potential antibacterial activity.

Abstract

Food security requires transformation of the agricultural sector through the application of technology. This article discusses a community service program aimed at addressing water scarcity and low interest in agriculture among young people at Ittaqollah Islamic High School in Ambon. The method used was community development with an interdisciplinary approach, combining geophysics for water exploration and Internet of Things (IoT) technology for smart irrigation. The activity began with subsurface mapping using geoelectric resistivity, which revealed a groundwater depth of >52 meters. This finding became the basis for implementing a rainwater harvesting solution installed on the school's roof. Next, an automatic irrigation system based on an ESP32 microcontroller was built and installed, integrated with a soil moisture sensor and controllable via smartphone. The program also included outreach and practical training for students and teachers. The results showed that the irrigation system operated optimally in both automatic and manual modes. This program demonstrates that the integration of geophysics and IoT can create sustainable solutions for water security, improve irrigation efficiency, and empower young people as future agricultural actors.
