Application of Appropriate Technology for Making Organic NPK Fertilizer by Utilizing Palm Oil Mill Waste in Bekiung Village

Urban Farm DB summary

The abstract describes a project with the Villa Ciomas RW 10 Farmer Group (PokTan Vici 10) in Ciomas Rahayu Village, Bogor, West Java, Indonesia, which practices urban farming on a small plot beside the Cisindangbarang River and already had a small fishpond but lacked aquaponics equipment. A community service team aimed to enhance the urban farming facility by installing aquaponics equipment, running workshops on basic hydroponics and aquaponics knowledge, exploring business potential, and providing hands-on cultivation practice, with monitoring and guidance throughout. The hydroponic/aquaponics installation succeeded, though nutrient supply from the fishponds alone was initially suboptimal, requiring supplemental hydroponic nutrients; hydroponic techniques were also introduced for vegetable cultivation. A pre/post-training questionnaire analysis showed the program significantly improved participants' knowledge and aquaponic skills (Wilcoxon signed-rank test, p<0.05). The aquaponics equipment was installed successfully, and participants gained foundational knowledge and skills enabling them to manage aquaponics systems independently through to harvest; the community plans to explore business opportunities selling hydroponic/aquaponic products.
