Innovation of Mycoparasites Trichoderma harzianum as a Catalyst in the Manufacture of Biofertilizers and Biopesticides in Anthracnose of Chili Plants

Abstract

Chili (Capsicum annuum L) is an important vegetable commodity that has high nutritional value and is widely favored but vulnerable stricken anthracnose disease. On the other hand, the production of processed food from fruits and vegetables always produces domestic waste in its processing that will pollute the environment. This study aims to determine potential of biofertilizer and biofungicide from fermented domestic waste MOL Trichoderma sp. The organic fertilizer derived from domestic waste fermented by Trichoderma sp. for 7, 10, and 14 weeks. Quality product was evaluated by measure of Nitrogen, P, and C-organic content and in vivo test. The test results showed that domestic waste product fermented by Trichoderma sp. at the fermentation time of 7 days had the highest levels of P, K, and C, organic respectively by 0.484%, 3.353%, and 40.18%. While the largest C-organic value in the 14-day fermentation period was 0.43%. The longer fermentation time will reduce the levels of P, K, and C-organic in POC but increase the value of C-organic. The highest Colletotrichum capsici inhibitory activity was found in POC with a fermentation time of 14 days (about 2 weeks) at 97.54%, the longer the fermentation time, the higher the inhibitory activity.
