Abstract
Fusarium sp. merupakan patogen tular tanah yang dapat menyebabkan berbagai penyakit tanaman. Salah satu alternatif pengendalian yang ramah lingkungan adalah menggunakan jamur antagonis Trichoderma sp. Penambahan molase sebagai sumber karbon diduga dapat mempengaruhi pertumbuhan jamur dan aktivitas antagonistiknya. Penelitian ini bertujuan untuk mengetahui pengaruh molase terhadap pertumbuhan Trichoderma sp. dan Fusarium sp., serta pengaruh beberapa konsentrasi molase terhadap kemampuan antagonistik Trichoderma sp. dalam menghambat Fusarium sp. secara in vitro. Penelitian dilakukan di laboratorium menggunakan dua percobaan, yaitu (1) pengaruh molase terhadap pertumbuhan Trichoderma sp. dan Fusarium sp., serta (2) pengaruh kombinasi konsentrasi molase (0–5%) dan Trichoderma sp. terhadap pertumbuhan Fusarium sp. Parameter yang diamati meliputi diameter koloni jamur dan persentase daya hambat Trichoderma sp. terhadap Fusarium sp. Hasil penelitian menunjukkan bahwa penambahan molase 3% tidak berpengaruh nyata terhadap pertumbuhan Trichoderma sp., namun cenderung menekan pertumbuhan Fusarium sp. Selain itu, variasi konsentrasi molase tidak memberikan pengaruh nyata terhadap daya hambat Trichoderma sp. terhadap Fusarium sp. Secara umum, molase tidak meningkatkan aktivitas antagonistik Trichoderma sp. terhadap Fusarium sp. Kata kunci : antagonisme, Fusarium sp., molase, pengendalian hayati, Trichoderma sp. Fusarium sp. is a soil-borne pathogen that can cause various diseases in plants. One environmentally friendly control alternative is the use of antagonistic fungi such as Trichoderma sp. The addition of molasses as a carbon source is suspected to influence fungal growth and its antagonistic activity. This study aimed to determine the effect of molasses on the growth of Trichoderma sp. and Fusarium sp., as well as the effect of several molasses concentrations on the antagonistic ability of Trichoderma sp. in inhibiting Fusarium sp. in vitro. The study was conducted in the laboratory through two experiments: (1) the effect of molasses on the growth of Trichoderma sp. and Fusarium sp., and (2) the effect of the combination of molasses concentrations (0–5%) and Trichoderma sp. on the growth of Fusarium sp. The observed parameters included fungal colony diameter and the percentage of inhibition of Trichoderma sp. against Fusarium sp. The results showed that the addition of 3% molasses had no significant effect on the growth of Trichoderma sp., but tended to suppress the growth of Fusarium sp. Furthermore, variations in molasses concentration did not significantly affect the inhibitory ability of Trichoderma sp. against Fusarium sp. Keywords : antagonism, biological control, Fusarium sp., molasses, Trichoderma sp.
