Abstract

One of the basic needs for humans is the availability of clean water that can be used for bathing, washing and also consumption. Sources of clean water can be obtained from dug wells, drilled wells, artesian wells, PDAMs and mountain springs. Artesian wells tap water in a confined aquifer layer which is limited by an insulating layer which naturally functions to maintain hydrostatic pressure and limit it to the free aquifer, where in this layer the influence of contamination is less. Kelambir Village has 4 artesian wells that are 30 years old spread across several hamlets, one of which is in hamlet III, Kelambir Village. People are free to use it for various purposes such as cooking, washing and bathing. The artesian well in Kelambir III hamlet was used as a model by the village head to provide clean water for residents by building a water reservoir tower measuring 2x2x2 and a height of 7 m above ground level to be able to channel water to the furthest places more than 3 km away. The characteristics of water from artesian wells are still slightly poor, characterized by changes in color and the presence of sediment. For this reason, the implementation team offers a solution in the form of providing a water filter installation to obtain water that is good quality and suitable for consumption. The water quality obtained after carrying out this activity was much better than the water samples obtained previously.

Abstract

The rapid growth of global energy demand and the urgent need to reduce greenhouse gas emissions have accelerated the transition toward renewable energy technologies, with solar photovoltaic (PV) systems playing a central role. In Indonesia, high solar irradiation provides significant potential for PV adoption, yet challenges remain in human resource capacity and technical readiness, particularly in rural areas where off-grid systems are critical. This study presents the design, development, and testing of a 200 Wp off-grid PV training module aimed at bridging the gap between theoretical knowledge and practical skills in renewable energy education. The module integrates two 100 Wp PV panels, a 100 Ah lithium-ion battery, an MPPT charge controller, and a 500 W pure sine wave inverter, all mounted on a modular acrylic platform to enable repeated assembly and disassembly for training purposes. Experimental testing under tropical conditions demonstrated stable PV output (Voc 19.8–21.5 V, Isc 4.8–5.4 A), efficient battery charging within 8 hours to full capacity, and reliable discharging performance sustaining DC loads for 18 hours and AC loads for 12–14 hours. Inverter efficiency averaged 92%, with minimal waveform distortion under typical loads. These results confirm the module’s reliability and educational value, offering a robust platform for vocational training and community-based capacity building. The study contributes to Indonesia’s renewable energy transition and supports Sustainable Development Goal 7 by enhancing technical education and workforce readiness for solar PV deployment.
