Evaluasi Kinerja Peningkatan Kapasitas Pengomposan dari Campuran Blotong, Bagas, dan Abu Ketel

Abstract

Composted filter cake, bagasse, and boiler ash on laboratory scaled which used aerated pile method had generated an optimum initial C/N and resulted the best compost quality. Meanwhile in order to be applied directly in industrial scale, the evaluation of laboratory scaled co-composting performance was needed along with increased processing capacity. The aim of this study was to compare larger scale of co-composting performance evaluation with laboratory scale. Capacity enhancement was done by increasing the capacity process from laboratory scaled of 5 kg to 100 kg. The evaluated performance parameters in co-composting were composting rate and the effect of aeration during composting. While constant factors, as same as capacity of 5 kg’s, were reactor geometrical congruency, initial C/N and aeration treatment. Compost mixture had initial C/N value of 50 and active aeration treatment of 0.4 L/min.kg was given in for 1 hour per day in the first week. The result showed that there were no any significant differences of composting rate between 5 kg and 100 kg. Besides, active aeration did not give significant effect to process condition and the composting rate in 100 kg scaled co-composting. Financial analysis of composting was able to bring profits based on the equation of B/C ≥1.
