Abstract: Research "Test the Effectiveness of Gamal Leaf Extract (Gliricidia maculata) as a Biofungicide on Pathogenic Fungi Colletothricum capsici, Fusarium oxysporum and Cercospora capsici Causes of Disease in Red Chili Plants (Capsicum annum L.) In-Vitro" aims to determine the effectiveness of gamal leaf extract (Gliricidia maculata) as a biofungicide for pathogenic fungi (Colletotrichum capsici, Fusarium oxysporum and Cercospora capsici) causes of disease in red pepper plants (Capsicum annum L.). This study used Non Factorial Complete Random Design (RAL Non Factorial) with 3 replications. Treatment factors of gamal leaf extract concentration are ED0 = negative control (without treatment); ED1 = Positive control (0.2% synthetic fungicide); ED2 = 10% gamal leaf extract; ED3 = 20% gamal leaf extract; ED4 = 30% gamal leaf extract; ED5 = 40% gamal leaf extract; ED6 = 50% gamal leaf extract; ED7 = 60% gamal leaf extract; ED8 = 70% gamal leaf extract; ED9 = 80% gamal leaf extract; ED10 = 90% gamal leaf extract; ED11 = 100% gamal leaf extract. The results of research on gamal leaf extract (Gliricidia maculata) were effective for controlling pathogenic fungi (Colletotrichum capsici, Fusarium oxysporum and Cercospora capsici). At ED3 concentration = 20% gamal leaf extract, the highest inhibitory percentage of Colletotrichum capsici was 82.49%, at ED5 concentration = 40% gamal leaf extract obtained the highest inhibition percentage of Fusarium oxysporum was 84.67% and ED5 concentration = gamal leaf extract 40 % obtained the highest inhibition percentage of Cercospora capsici is 87.73%. The concentration of 20% gamal leaf extract and 40% of the inhibition of each fungus was equivalent to the Benlox 50 WP synthetic fungicide.

Secara In-Vitro” bertujuan untuk mengetahui keefektifan dari ekstrak daun gamal (Gliricidia maculata) sebagai biofungisida terhadap cendawan patogen (Colletotrichum capsici, Fusarium oxysporum dan Cercospora capsici) penyebab penyakit pada tanaman cabai merah (Capsicum annum L.). Penelitian ini menggunakan Rancangan Acak Lengkap Non Faktorial (RAL Non Faktorial) dengan 3 ulangan. Faktor perlakuan konsentrasi ekstrak daun gamal yaitu ED0 = Kontrol negatif (tanpa perlakuan); ED1 = Kontrol positif (fungisida sintetis 0,2%); ED2 = ekstrak daun gamal 10%; ED3 = ekstrak daun gamal 20%; ED4 = ekstrak daun gamal 30%; ED5 = ekstrak daun gamal 40%; ED6 = ekstrak daun gamal 50%; ED7 = ekstrak daun gamal 60%; ED8 = ekstrak daun gamal 70%; ED9 = ekstrak daun gamal 80%; ED10 = ekstrak daun gamal 90%; ED11 = ekstrak daun gamal 100%. Hasil penelitian ekstrak daun gamal (Gliricidia maculata) efektif untuk mengendalikan cendawan patogen (Colletotrichum capsici, Fusarium oxysporum dan Cercospora capsici). Pada konsentrasi ED3 = ekstrak daun gamal 20% didapat persentase penghambatan tertinggi Colletotrichum capsici adalah 82,49%, pada konsentrasi ED5 = ekstrak daun gamal 40% didapat persentase penghambatan tertinggi Fusarium oxysporum adalah 84,67% dan pada konsentrasi ED5 = ekstrak daun gamal 40% didapat persentase penghambatan tertinggi Cercospora capsici adalah 87,73%. Konsentrasi ekstrak daun gamal 20% dan 40% dari penghambatan masing-masing jamur setara dengan fungisida sintetis Benlox 50 WP.
