Abstract
This study was aims to determine the viability of chitinolytic bacterial isolates in some carrier media and to know the potential of chitinolytic bacterial isolates in various carrier media in controlling the disease of sprout caused by F. oxysporum and S. rolfsii on red pepper plant. The method used by measuring the viability and ability of bacteria in growing media and carrier media on MGMK media after storage of carrier media for 90 days. Bacteria NR09 has good viability on peat carrier media and palm oil bunch compost and has the potential to inhibit attack of pathogenic fungi S. rolfsii and F. oxysporum.

Summary
Potensi Bakteri Kitinolitik NR09 pada Beberapa Media Pembawa dalam Menghambat pencegahan dan pemberantasan dalam. METODE PENELITIAN Persiapan Bakteri Kitinolitik, Jamur patogen dan Media Pembawa. Media pembawa yang digunakan adalah tanah gambut dan kompos janjang kelapa sawit. Media pembawa potensial untuk menghambat pertumbuhan fungi patogen pada tanaman. Bakteri kitinolitik mampu dibuat dalam 4 variasi yaitu tanah gambut saja, tanah gambut yang ditambahkan dengan 2% koloidal kitin, menurunkan rebah kecambah cabai kompos janjang sawit saja dan kompos merah hingga 80% (Netti, 2014). Dalam hal ini penelitian ini bertujuan untuk menguji dan meneliti janjang sawit yang ditambahkan dengan 2% koloidal kitin. Peningkatan pH gambut dilakukan dengan penambahan viabilitas sel bakteri kitinolitik NR09 pada beberapa media pembawa. NR09 memiliki persentase garam minimum merupakan media yang digunakan untuk perbanyakan sel bakteri dan diinkubasi hingga kerapatan penghambatan yang tertinggi terhadap sel ≈ 108 sel/ml.
