EFEKTIVITAS MIKROBA DARI PEMBIAKAN BERSERI Colletotrichum sp., KITIN DAN TANAMAN KUNYIT TERHADAP PATOGEN ANTRAKNOSA CABAI

---

Red chili is an important crop in Indonesia, but faces high risks from pest attacks and anthracnose disease caused by the fungus Colletotrichum sp. Chitin from crustacean shell waste and turmeric can be used to control this disease. Chitin and compounds in turmeric effectively inhibit fungal growth. This study aims to determine the effectiveness of suppressive microbes against Colletotrichum spp. through serial propagation using media containing Colletotrichum, chitin, and turmeric plants in inhibiting the growth of Colletotrichum spp., the causative agent of anthracnose in red chili plants. The research was conducted from July to December 2025 at the Phytopathology Laboratory, Plant Protection Study Program, Department of Pests and Plant Diseases, Faculty of Agriculture, Sriwijaya University. This study used a split-plot design with the main plot consisting of 2 levels of enrichment materials and the subplot consisting of 3 serial propagation cycles with 3 replications. The main plot levels were enrichment materials Colletotrichum sp. + sugar, and sugar + chitin + Colletotrichum sp. The subplot levels were cycles 1, 2, and 3. The observed variables were colony growth inhibition and electrical conductivity (EC). Research results show that serial propagation of turmeric plants on cocopeat supplemented with Colletotrichum sp. mycelium effectively inhibits colony growth, significantly increases the EC value of the media, and causes lysis of Colletotrichum sp. fungus. In contrast, serial propagation of turmeric plants on cocopeat supplemented with Colletotrichum sp. mycelium and chitin powder shows declining inhibition with increasing cycles, with the lowest inhibition at the third cycle. Serial propagation of turmeric plants on cocopeat supplemented with Colletotrichum sp. mycelium without chitin powder is most effective in producing antagonistic microbes capable of inhibiting Colletotrichum sp. growth. Keywords: Colletotrichum sp., Chitin Powder, Electrical Conductivity (EC) Suppressive Microbes.
