The Effectiveness of Hydroponic Technology in Organic Vegetable Production in Urban Areas"

Abstrak

Rapid urban population growth has limited agricultural land and increased demand for healthy food, particularly organic vegetables. Hydroponic technology is considered one solution for urban agriculture, capable of increasing production efficiency without relying on large areas of land. This study aims to assess the effectiveness of hydroponic technology in organic vegetable production in urban areas through a literature review. The method used was a systematic review of national and international scientific articles published between 2013 and 2024, sourced from Google Scholar, Garuda, Scopus, and DOAJ. The study results indicate that hydroponic systems can increase vegetable productivity by 20–50% compared to conventional systems, save water use by 70–90%, and produce more hygienic and environmentally friendly products. However, major challenges include initial investment costs, dependence on controlled nutrients, and limited organic certification for hydroponic systems. The study concludes that hydroponic technology is effective in supporting organic vegetable production in urban areas when combined with appropriate nutrient management and supporting policies.
