Abstract

The coastal area of Muara Angke in North Jakarta grapples with significant challenges regarding access to clean water, compounded by limited energy availability. In 2024, a desalination project utilizing reverse osmosis (RO) technology was launched to address this issue, with a capacity to produce 320 liters of clean water per hour. A key feature of this initiative is its reliance on solar energy, which offers a sustainable solution to the region’s energy constraints. However, to ensure the project's long-term viability, it is essential to conduct an economic evaluation, particularly focusing on the cost of producing the desalinated water. This cost is intricately linked to the energy required to power the reverse osmosis (RO) system. Specifically, the Cost of Energy (CoE) plays a crucial role in determining the price of the desalinated water. To assess the economic feasibility of the solar-powered desalination system, HOMER simulation software was used to model the performance of the solar power system, considering factors such as solar energy potential, system capacity, and the financial costs of the solar infrastructure, including the solar panels, inverters, and battery storage. The simulation results reveal an annual energy production of 58,900 kWh and a CoE of Rp 575.55 per kWh, which directly influences the cost of water production, resulting in a price of Rp 17.27 per liter for the desalinated water. This study highlights the essential role of renewable energy sources in ensuring the sustainability of desalination systems and emphasizes the importance of accurate cost analysis to make such systems economically viable in coastal communities like Muara Angke. By integrating RO technology with solar energy, this initiative offers a promising approach to addressing water scarcity while reducing reliance on non-renewable energy sources, ultimately providing a long-term solution to clean water access.

Abstract

Student health center as a forum for providing Health Education for schoolchildren is expected to help improve the quality of education and achievement reflected in a healthy lifestyle and environment. Based on the observations made by the community service team, it is known that the implementation of the Student health center at SDN Gisik Cemandi is still straightforward due to limited funds, existing facilities, and infrastructure, and there is no form for recording and reporting Student health center activities. The purpose of this community service activity is to evaluate the activities of the student health center role at SDN Gisik Cemandi, Sedati, in Sidoarjo Regency. This community service activity was carried out on November 13-14th through small group discussions with the headmaster, teachers, and Student health center administrators at SDN Gisik Cemandi to identify needs in implementing the Student health center program. Based on the results of the cases found during the community service that had been carried out, the community service team made some products, namely: the form of a student health center service flow in the form of roller banners and videos as well as a student health center register book. The product is expected to improve the quality of Student health center services at SDN Gisik Cemandi.
