Inokulasi Mikroba Selulolitk untuk Mempercepat Proses Pengomposan Sampah Pasar dan Pengaruh Kompos terhadap Produksi dan Usahatani Sayuran

Abstract

The local government spends a lot money and effort to solve the problems of the city waste. City wastes have been reported to contain as much as 80 – 90% of decomposable organic wastes. These organic wastes can be converted to useful compost. The aims of this study were (1) to study the effect of inoculation of cellulolytic microbes to city wastes to speed up the decomposition process of city wastes and (2) to evaluate the effect of compost on production economic analysis of vegetables i. e. Chinese cabbage (Brassica chinensis) and kangkoong (Ipomoea reptans Poir). Market wastes were place on triangle bamboo skeleton to a width of 1.50 m and high of 1.00 m with a length of 2.50 m. The weight of these city wastes was 2 ton with a volume. Six waste piles were prepared and inoculated with four sources of cellulolytic microbes (stardec, cow rumen, goat rumen and chicken manure). As much as 5.25 kg of cellulolytic inoculants were throughly mix with city waste. Temperature, pH, C/N ratio, respiration rate, weight losses of composted materials were measured regularly. The effect of five compost produced were evaluated for their effect of growth of Chinese cabbage and kangkoong. The treatments tested were control (without compost), inorganic fertilizer, combination between compost and inorganic fertilizer, compost with goat rumen inoculant and compost with stardec. Height, fresh weight and nutrient uptake were measured.The results showed that the cellulolytic microbe significantly increased the composting process of city waste compost. The best cellulolityc microbes inoculant were mix inoculant, cow rumen inoculant, stardec and chicken manure inoculant. These inoculant reduced the composting process by six days. Combination between organic fertilizer and inorganic fertilizer showed the highest yield of Chinese cabbage and kangkoong production. This treatment increased the yield 469% of Chinese cabbage and 290% of kangkoong above without any fertilizers and 175% and 110% above the 100% inorganic fertilizer.
