Abstract: Penyakit rebah kecambah umumnya disebabkan oleh patogen tular tanah Fusarium sp. yang menghambat pertumbuhan pada saat proses budidaya tanaman cabai merah. Fungi amilolitik merupakan fungi yang dapat menghasilkan enzim amilase, fungi ini memiliki aktivitas amilolitik yang dapat berkontribusi besar pada proses dekomposisi bahan-bahan organik dan juga dapat digunakan sebagai pemacu pertumbuhan tanaman serta berperan penting dalam menekan penyakit dengan penghambatan patogen yang terdapat di tanah. Penelitian dilakukan dengan metode pengujian dual culture method. Hasil uji menunjukkan bahwa fungi amilolitik memiliki potensi dalam menekan pertumbuhan fungi patogen Fusarium oxysporum melalui mekanisme kompetisi nutrisi dan ruang, serta mekanisme antibiosis dengan memproduksi metabolit sekunder seperti enzim. Hasil uji antagonis menunjukkan bahwa fungi amilolitik dapat menghambat pertumbuhan Fusarium oxysporum secara makroskopis, yang ditandai dengan pertumbuhan dan perkembangan yang melambat. Selain itu fungi amilolitik juga mampu menekan pertumbuhan fungi patogen dengan menyebabkan malformasi atau perubahan pada bentuk hifa Fusarium oxysporum seperti hifa melilit, hifa bengkok serta hifa lisis. Seedling blight disease is generally caused by the soil-borne pathogen Fusarium sp., which inhibits growth during the cultivation of red chili peppers. Amylolytic fungi are fungi that can produce amylase enzymes. These fungi have amylolytic activity that can greatly contribute to the decomposition of organic materials and can also be used as plant growth stimulants and play an important role in suppressing diseases by inhibiting pathogens in the soil. The research was conducted using the dual culture method. The test results showed that amylolytic fungi have the potential to suppress the growth of the pathogenic fungus Fusarium oxysporum through the mechanisms of nutrient and space competition, as well as the mechanism of antibiosis by producing secondary metabolites such as enzymes. The antagonistic test results showed that amylolytic fungi can inhibit the growth of Fusarium oxysporum macroscopically, which is characterized by slow growth and development. In addition, amylolytic fungi are also able to suppress the growth of pathogenic fungi by causing malformations or changes in the shape of Fusarium oxysporum hyphae, such as twisting, bending, and lysis.
