The Modified Hydroponic Kit Based on Self-Fertigation System Designed for Remote Areas

Hydroponics has great potential to improve the sustainability of food supplies in various regions presently and future. However, studies on proposed hydroponic technology specifically for remote areas are still very limited, with majority focusing urban areas. Limited resources, such as electricity supply, main obstacles implementing hydroponics Therefore, this study proposes a breakthrough based self-fertigation system that can work without effective efficient plant growth. This employs descriptive quantitative methodology. The was applied spinach (Amaranthus dubius) green red varieties, from January April 2021 during wet season tropical climate Indonesia. Spinach seeds were sown placed at nursery 10 days net pots containing rockwool 25 mm cubes growth media, then transferred kit until harvesting. Based analysis, microclimate conditions had safe range consistent standards. modified provided good fertigation quality including temperature, electrical conductivity, hydrogen dissolved oxygen plants. total consumption amounted 46.64 L 20 planting (equal 0.012 L/plant day−1) low evapotranspiration (0.89 mm/day). In addition, higher productivity 1.34 kg/m2 than 0.71 kg/m2. nutritional analysis results also showed is superior calcium, iron, phosphor, vitamin C, while potassium magnesium. used successfully cultivate plants morphological qualities. type bright outlook near future must be continuously developed.
