Twenty two yeast isolates were isolated from banana, rambutan, red chilli, tomato, and eggplant fruits. Screening for antagonistic yeast using well test showed that 5 isolates of yeast (CMM-1, CMM-3, CMM-4, TMM-1, and EMM-11) completely inhibited the growth of <span style="text-decoration: underline;">C.</span> <span style="text-decoration: underline;">capsici</span>. Based on the result of biocontrol assay of the pathogen in vivo, four yeast isolates (CMM-3, CMM-4, TMM-1, and EMM-11) completely inhibited <span style="text-decoration: underline;">C.</span> <span style="text-decoration: underline;">capsici</span> in vivo. Identification using morphological and molecular characteristics showed that these four yeast isolates were <span style="text-decoration: underline;">Issatchenkia</span> <span style="text-decoration: underline;">orientalis</span>.</em></p><p><em>Keywords: antagonistic yeast, antrachnose, biocontrol, <span style="text-decoration: underline;">Issatchenkia</span> <span style="text-decoration: underline;">orientalis</span></em></p><p> </p><p align="center"><strong>ABSTRAK</strong><strong></strong><strong> <br /></strong></p><p>Antraknosa pada buah cabai yang disebabkan oleh <em>Colletotrichum capsici</em> dapat menyebabkan penurunan produksi dan kualitas buah cabai. Penggunaan agens pengendalian hayati dapat menjadi salah satu alternatif untuk mengendalikan <em>C. capsici</em>. Khamir merupakan salah satu agens pengendalian hayati yang berpotensi mengendalikan <em>C. capsici</em>. Penelitian ini bertujuan menguji potensi antagonistik khamir pada buah-buahan dan sayuran terhadap <em>C. capsici. </em>Sebanyak 22 isolat khamir diisolasi dari buah rambutan, pisang, cabai merah besar, tomat, dan terung ungu. Seleksi khamir antagonis menggunakan uji sumur diperoleh sebanyak 5 isolat khamir, yaitu isolat CMM-1, CMM-3, CMM-4, TMM-1, dan EMM-11 menghambat total pertumbuhan <em>C. capsici</em>. Isolat CMM-3, CMM-4, TMM-1, dan EMM-11 menghambat total pertumbuhan <em>C. capsici in vivo</em>.
