Effect of Production Technique on Corncob Biochar Quality

Abstract

Lampung Selatan Regency is one of the centers of corn production in Lampung, Indonesia. Along with the increase in corn production, the resulting corn biomass waste also increases. Corn biomass waste such as cobs can be utilized into more useful products such as biochar which is useful as a soil amendment. The purpose of this research was to evaluate the quality of biochar based on its production technique. The three biochar production techniques used were traditional soil pit, closed drum kilns, and open drum kilns.. The quality of biochar was determined by the temperature and period of the pyrolysis process, which was greatly influenced by the selected production technique. The results showed that the closed drum kiln technique produces biochar with better properties for increasing soil fertility because it produces the biochar with the highest fixed carbon and CEC.
