Abstract

Indonesia produces 64 million tons of plastic waste every year and 3.2 million tons of it is thrown into the sea, so research needs to be done to create plastic that is environmentally friendly and easily decomposed (bioplastic). Alginate and carrageenan are polysaccharides produced from seaweed which have potential as materials for making bioplastics. This research aims to determine the effect of alginate and carrageenan on the quality, physical properties, mechanical properties and biodegradability of carrageenan-chitosan bioplastics with glycerol plasticizer. Carrageenan is obtained from extraction of Kappaphycus sp. who comes from the Yapen Islands, Papua Province. Making a carrageenan bioplastic solution by dissolving carrageenan flour (1; 1.5; 2; 2.5 grams) and 5 ml of glycerol in 100 ml volume of vingga distilled water then heating using a magnetic stirrer for 15 minutes at 90oC. The process of making a chitosan solution is by dissolving 2 grams of chitosan, 3 ml of glycerol, and 1 ml of glacial acetic acid in 94 ml of distilled water then heating with a magnetic stirrer for 10 minutes. The research results show that. The best concentration of carrageenan in the alginate-carrageenan composite bioplastic is 1.5 grams because it has physical and mechanical properties that meet the Japanese Industrial Standard and SNI 7188.7:2016 except for water resistance.

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
