COASTAL WASTE PROCESSING INNOVATION: SEAWEED LIQUID FERTILIZER AND COCONUT-WOOD BRIQUETTES

Abstract

Community service activities carried out in Lamaru Village, East Balikpapan, aim to overcome the problem of coastal waste, especially seaweed, coconut fiber, and wood waste that have not been optimally utilized. Through an innovative work program,seaweed waste is processed into liquid organic fertilizer (POC), while coconut fiber and ironwood are processed into briquettes asan alternative energy source. The implementation method includes socialization, demonstration, and training for the local community regarding the process of processing waste into products with sales value. The results of the community service showthat liquid organic fertilizer from seaweed can significantly increase the growth of eggplant plants compared to the control, whilecoconut fiber briquettes, and mixed coconut fiber and ironwood briquettes have a fairly high calorific value and can be used as environmentally friendly fuel. This activity not only provides a solution to waste management, but also increases community skillsand awareness in utilizing the potential of local resources.
