Abstract

Abstrak Kegiatan bertujuan untuk mengembangkan lampu berbasis air laut sebagai sumber energi alternatif untuk nelayan di Pulau Kosong, Jayapura. Penerapan teknologi ini diharapkan dapat mengurangi biaya operasional nelayan, yang saat ini masih bergantung pada sumber energi konvensional. Lampu air laut memanfaatkan air laut yang melimpah di sekitar pulau sebagai bahan baku, sehingga lebih ekonomis dan ramah lingkungan dibandingkan penggunaan bahan bakar fosil. Program ini juga mencakup pelatihan dan pendampingan bagi nelayan untuk memastikan adopsi teknologi yang efektif. Melalui evaluasi, lampu ini terbukti mampu meningkatkan kualitas hidup nelayan dengan menyediakan penerangan yang andal dan berkelanjutan. Kata kunci: lampu air laut; energi terbarukan;  nelayan pulau kosong; pengurangan biaya operasional; teknologi ramah lingkungan AbstractThis program aims to develop saltwater-based lamps as an alternative energy source for fishermen in Pulau Kosong, Jayapura. The implementation of this technology is expected to reduce operational costs for fishermen, who currently rely on conventional energy sources. The saltwater lamps utilize the abundant seawater around the island as raw material, making them more economical and environmentally friendly compared to fossil fuels. The program also includes training and support for fishermen to ensure effective adoption of the technology. Through evaluation, these lamps have proven to enhance the fishermen's quality of life by providing reliable and sustainable lighting. Keywords: saltwater lamp; renewable energy; pulau kosong fishermen; operational cost reduction; environmentally friendly technology

Abstract

Laundry activities utilizing detergents as cleaning agents generate non-degradable waste, posing environmental and health hazards. Laundry services, or laundries, have experienced rapid growth in Jayapura City, resulting in substantial laundry waste discharge directly into the environment. Activated carbon, with its porous and highly absorptive nature, proves effective to absorb waste particles. This community engagement initiative focuses on providing education and implementing small to medium-scale laundry waste treatment for micro, small, and medium-sized enterprises. The project collaborates with Zifara Laundry, a laundry business located in Waena, Heram District, Jayapura City. The partner receives essential education on the importance of pre-treating laundry waste before disposal into the environment. The engagement team installs waste filters based on activated carbon, augmented with silica sand, gravel, and cotton filters in each layer. As a result, both the business owner and laundry workers gain a profound understanding of the significance of treating laundry waste before environmental discharge. The waste filters installed by the engagement team on the central laundry waste disposal channel contribute to an improvement in laundry wastewater quality. Turbidity levels decrease from a scale of 150-200 NTU to 1-2 NTU after the installation of activated carbon-based laundry waste filters.
