Implementation of a Wick-Based Hydroganic System as a Model for Enhancing Production and Food Self-Reliance at Bina Siwi Orphanage

Abstract

Community-based food security plays an important role in empowering vulnerable groups, including persons with disabilities. Bina Siwi Orphanage previously cultivated mustard greens using conventional soil-based methods with low productivity and without measurable nutrient management. This activity aims to increase mustard greens production capacity by applying a simple, practical wick-based organic hydroponic (hydroganic) system. A participatory approach was employed through four stages: observation, system planning, implementation, and productivity evaluation. The system used PVC (Polyvinyl Chloride) pipes as nutrient reservoirs and inert growing media, and flannel wicks, without the use of pumps or electricity. Cultivation was conducted for one planting cycle, with a harvest at 35 days after transplanting. The results showed an increase in production from approximately 3 kg to 8 kg per cycle, a 166% increase over the previous conventional method. The plants exhibited uniform vegetative growth without significant nutrient deficiency symptoms. The improvement in yield was influenced by stable nutrient availability, regulated plant density, and consistent media moisture maintained through capillary action. In addition to increasing productivity, the program enhanced participants’ technical skills in systematic crop management from seedling to post-harvest handling. The wick-based hydroganic system proved feasible for implementation in social institutions with limited resources.
