Abstract

Water quality is one of the important factors to increase the success of aquaculture production besides disease factors and fish seed quality. Water quality in auaculture ponds greatly affects the growth, survival, and production of tilapia. Several factors that affect water quality are the acidity level (pH). The maximum pH value ranges from 6.5 to 8.5. This study aims to design an automatic water pH control system in tilapia ponds. The water quality control system in fish ponds is often done manually so it is less efficient. The system is designed by combining a pH sensor pump, and solenoid valves using ESP32 microcontroller. When the pH sensor detects a pH value of less than 6.5 or more than 8.5, the system will automatically change the water. The test results in the pond showed that the system was able to respond with the respective rise time and settling time values, namely 1240s and 1380s. Based on these results, it can be concluded that the pH control system that was built can function according to the design.

Abstract

The availability of clean water is a crucial issue in Jatimulyo Village, South Lampung Regency, particularly during the dry season. Residents face difficulties accessing water sources due to a limited understanding of the subsurface groundwater potential. In response to this problem, a team from the Sumatra Institute of Technology (ITERA) conducted a community service activity aimed at mapping this groundwater potential. This activity utilized the geoelectric resistivity method to identify subsurface structures and determine the locations and depths of potential aquifers for drilled wells. In its implementation, the team collaborated with the local village government and involved participants from the Geophysical Engineering and Petroleum and Gas Engineering Study Programs. In addition to technical surveys, the team also conducted a socialization of their findings and provided education on groundwater utilization. This event, attended by residents, local neighborhood (RT) heads, and village officials, highlighted the importance of proper aquifer identification, well maintenance techniques, and strategies for ensuring water resource sustainability. This initiative received positive appreciation from the village head and residents, who hope the results of the ITERA study can provide a concrete solution to address the challenges of clean water availability in their region.
