Uji Potensi Hasil Produksi Pupuk Organik Granul Limbah Biogas terhadap Pertumbuhan Tanaman Tomat (Solanum lycopersicum)

Abstract

Problems encountered in the development of Indonesian agriculture is declining quality of agricultural land. The problem is exacerbated by the use of inorganic fertilizer (chemical fertilizer), needed a solution to reduce the use of inorganic fertilizers, one of them with the production of organic fertilizer from waste biogas potential tested against Tomato (Solanum lycopersicum). Waste biogas from anaerobic biogas production, will generate solid and liquid wastes. Furthermore, solid waste created granules, and tested its potential for growth of tomato plants. The purpose of the study (1). Knowing the effectiveness of organic fertilizer granules on the growth of tomato plants (Solanum lycopersicum). 2). Determine the effect of various manure biogas waste in the manufacture of organic fertilizers, on the growth of tomato plants (Solanum lycopersicum). The method used experiments, and experimental design used completely randomized design (CRD) with 1 factor is the type of organic fertilizer granules with different animal manure (chicken, goat and chicken + goat). Parameters measured were plant height, number of leaves, plant diameter, and biomass results showed that organic fertilizer granules chicken manure, goats, chickens and goats give a better effect on the growth of tomato plants compared to control, so effective as an alternative to the use of chemical fertilizers, thus expected to have an impact on the environmentfriendly

agricultural healthy. Organic fertilizer granules goat manure most effective against the growth of tomato plants, especially plant height. Chicken manure organic fertilizer granules give the best effect on stem diameter growth and biomass plants.
