Abstract

Tanaman cabai rawit merupakan tanaman yang banyak dibudidayakan di Indonesia. Namun, hasil produksi tanaman cabai rawit belum mampu mencukupi permintaan penduduk. Penyakit antraknosa yang disebabkan oleh jamur patogen Colletotrichum capsici merupakan salah satu penyakit yang pada serangan berat menyebabkan penurunan hasil produksi mencapai 100%. Pengendalian yang pernah dilakukan yaitu dengan menggunakan fungisida sintetik. Namun, fungisida sintetik menyebabkan kerusakan karena residu yang dihasilkan. Pemanfaatan agens antagonis menjadi salah satu upaya pengendalian patogen Colletotrichum sp. Agens antagonis yang digunakan yaitu Trichoderma sp., Gliocladium sp., dan Bacillus sp. Agens antagonis yang digunakan ini telah diformulasikan menjadi produk biofungisida. Penelitian dilakukan di laboratorium Mikrobiologi serta lahan percobaan milik PT. Petrosida Gresik. Metode penelitian yang dilakukan dalam penelitian menggunakan metode Rancangan Acak Lengkap (RAL) dan Rancangan Acak Kelompok (RAK) dengan 7 perlakuan dan 4 ulangan. Penelitian dilakukan secara in-vitro maupun in-vivo. Parameter pengamatan yang diuji meliputi daya hambat, intensitas serangan serta tingkat efikasi. Hasil pengamatan menunjukkan bahwa pemberian biofungisida berbahan aktif konsorsium mikroba Trichoderma sp., Gliocladium sp., dan Bacillus sp. maupun mikroba tunggal berpengaruh nyata dalam menghambat pertumbuhan penyakit antraknosa secara in-vitro serta in-vivo. Konsorsium mikroba antagonis fungsional dengan konsentrasi 5 gram/liter memberikan hasil terbaik dalam menekan pertumbuhan penyakit antraknosa baik secara laboratorium maupun lapang.

English Abstract

Cayenne pepper is a plant that is widely cultivated in Indonesia. However, the production of cayenne pepper plants has not been able to meet the demand of the population. Anthracnose disease caused by the pathogenic fungus Colletotrichum capsici is a disease which in severe attacks causes a decrease in production yields up to 100%. Control that has been done is by using synthetic fungicides. However, synthetic fungicides cause damage due to the residue they produce. The use of antagonistic agents is one of the efforts to control the pathogen Colletotrichum sp. The antagonistic agents used were Trichoderma sp., Gliocladium sp., and Bacillus sp. The antagonist agent used has been formulated into a biofungicide product. The research was conducted in the Microbiology laboratory and the experimental field owned by PT. Petrosida Gresik. The research method used in this study used a completely randomized design (CRD) and randomized block design (RBD) with 7 treatments and 4 replications. The research was conducted in-vitro and in-vivo. The observed parameters tested included inhibition, attack intensity and level of efficacy. The results showed that the administration of biofungicides with active ingredients from the microbial consortium Trichoderma sp., Gliocladium sp., and Bacillus sp. as well as single microbes have a significant effect on inhibiting the growth of anthracnose disease in-vitro and in-vivo. The functional antagonist microbial consortium with a concentration of 5 grams/liter gave the best results in suppressing the growth of anthracnose disease both in the laboratory and in the field.
