Abstract
This study examines the ability of liquid organic waste carriers to increase the antifungal activity of the active ingredient Bacillus sp DB12, which has been stored for 12 weeks against the pathogen Fusarium oxysporum f.sp. cepae. The research method was carried out in an experimental laboratory using a completely randomized design (CRD) with a single factor in the form of a liquid waste carrier consisting of 9 treatments. The composition of liquid tofu waste (LCT), coconut liquid waste (LCK), and rice washing liquid waste (LCB) was determined as follows: 100% LCT (A1), 75% LCT + 25% LCK (A2), 50% LCT + LCK 50% (A3), LCT 25% + LCK 75% (A4), LCK 100% (A5), LCT 75% + LCB 25% (A6), LCT 50% + LCB 50% (A7), LCT 25% + 75% LCB (A8), and 100% LCB (A9). The results showed that the combination of 75% LCT + 25% LCK carriers increased the antifungal activity of Bacillus sp. DB12 compared to other carrier combinations. An increase in antifungal activity was indicated by an inhibition zone diameter of 13.03 mm during 12 weeks of storage.
