Abstract

The waste diapers, the second largest waste source after plastic, pose environmental challenges due to their slow degradation of 25-50 years. Reprocessing diaper waste, including utilizing Super Absorbent Polymer (SAP), is crucial. SAP's high absorption capacity aids in research for separating crude oil from water, particularly relevant for Indonesian oil wells with aging infrastructure. Emulsions in crude oil, stabilized by natural chemicals, require demulsification to prevent production issues, underscoring the importance of efficient water-oil separation methods. The research experimentally compares oil-in-water emulsion separation using SAP with and without SAP. The study utilizes waste-based ingredients like used diapers, and tests involve centrifuge processes at varying temperatures. SAP's osmotic properties enable high water absorption, impacting demulsification efficiency. This study investigates the impact of temperature on emulsion separation between water and crude oil. Testing at 26°C and 40°C reveals accelerated separation at higher temperatures due to reduced crude oil viscosity. Waste-containing tubes demonstrate better separation, with SAP absorbing water, enhancing separation efficiency. Increasing centrifuge speed and temperature improve oil-water separation, showcasing SAP's effectiveness in waste management processes. Research findings on crude oil-water separation using diaper waste conclude that demulsification is faster at 40°C due to decreased viscosity; with SAP waste, volumes of water are more efficient at 40°C; SAP's hydrophilic nature traps water in the gel network; SAP enhances separation effectiveness compared to non-SAP methods in saline solutions.

Abstract

This community service program titled "Socialization and Training on the Utilization of Solar Energy as an Environmentally Friendly Electricity Source in Karang Taruna, Gambir District" aimed to address the critical issues faced by the community due to their heavy reliance on unstable and costly fossil energy from PLN (the state-owned electricity company). The program also targeted the low understanding and practical skills related to solar energy and the underutilization of solar energy potential in urban settings. The implementation comprised two core components: socialization of solar energy and climate change impacts, and hands-on training on mini solar panel systems. Using interactive lectures, demonstrations, direct practices, and discussions, the program was conducted on March 16, 2025, involving 31 participants mainly from Karang Taruna members. A significant improvement in participants’ comprehension was observed, with average pre-test scores rising from 45 to 82, indicating an 82.22% increase. Furthermore, participant satisfaction reached 90.32%, alongside a 70.96% enhancement in practical ability to operate mini solar panel setups. Key outputs included teaching materials, posters, and scientific articles, collectively contributing toward enhanced community energy independence, reduced electricity costs, and promotion of clean energy adoption in urban areas.
