Abstract

Red onion (Allium cepa L.) is considered one of the most commonly used vegetables in the culinary arts in Indonesia. It has many benefits, one of them is contain antioxidants that promote good health. Conventional cultivation of red onion is depended on the implementation of inorganic fertilizers to improve the production and the usage of synthetic pesticides to keep plants from pests attack. In this research, we was produced the NPK slow release fertilizer that formulated for red onion. In the process of synthesized the NPK slow release fertilizer, some main materials used to comply the need of nitrogen (N), phosphor (P), and potassium (K), were Urea, Diammonium Phosphate (DAP), and Potassium Chloride (KCl). Beside those materials, we was also used zeolite as a matrix to increase the characteristic of fertilizer. In the process of making NPK slow release fertilizer, we can used char as a material. Char that produced from the gasification process of empty fruit bunch (EFB) called as EFB char. It is a potential material as a potassium source that can be used in the making of NPK fertilizer. In this research, we was synthesized NPK fertilizer using EFB char as a alternate source of potassium that substitute the potassium chloride which was generally used in making NPK fertilizer. The aim of this research was to formulate and synthesize the NPK fertilizer for red onion using EFB char as a potential source of potassium and then characterize the fertilizer (surface area, pore volume, and morphology test) to analyse the effect of utilization EFB char and adding some material as micronutrient such as Mg (MgSO4 fertilizer) and S (ZA fertilizer) to improve the growth of red onion plant.
