Pengaruh pupuk organik limbah padat industri crumb rubber terhadap pertumbuhan tanaman cabe (Capsicum frutescens)

The research about the influence of organic fertilizer of crumb rubber solid waste industry on chili plants (capsicum frutescens) growth had been done. The aim of the research was to evaluate the vegetative growth of chili plants treated with organic fertilizer that was made from crumb rubber solid waste industry and it was compared with chili plants treated was commercial organic fertilizer (SP -36). The organic fertilizer was made by mixing of soil, crumb rubber solid waste, cow fieces, talc, saw dust, and hull rices, using and aerab system. The variation of the amount of solid waste was 0%; 10%, 20%; 30%; and 40%, respectively. Fertilizing of chili plants was done by dasage variation i.e.1:1,5; and 2 kg/10m2 and control (without fertilizer) respectively. The observation was done on fourth month on vegetative growth including high plants, leaf length, and leaf width. The results showed that crumb rubber solid waste could be used as organic fertilizer for chili plants. The best growth of plants especially high was treated with 20% crumb rubber solid waste at dosage of 2 kg /10m2 is 38.2 cm, while the best growth of leaf length and leaf width was chili plant treated with 40% crumb rubber solid waste at dosage of 2 kg/10m2 was 10.0 cm and 6.2 cm.
