POTENSI BIJI JALI (Coix lacryma–jobi L.) SEBAGAI MEDIA PADAT UNTUK PERTUMBUHAN JAMUR Trichoderma harzianum

Abstract

Trichoderma harzianum can be grown on solid media containing carbohydrate organic matter such as jali’s seed (Coix lacryma–jobi L.)  This study aims to determine the effectiveness of jali’s seed as a growth medium for T. harzianum fungi. This study was conducted for 3 months from November 2021 to January 2022 using CRD (Complete Random Design) with five levels of treatment T1=25g rice as control, T2=15g rice : 10g jali, T3=12.5g rice : 12.5g jali, T4=10g rice : 15g Jali, T5=25g jali. The data were analyzed using ANOVA and continued with the Duncan test with a confidence level of 95%. The results showed that the use of solid media as a growth medium for the fungus T. harzianum had a significant effect on the average diameter of the fungus, wet weight, and spore density of the fungus T. harzianum. The results showed that the use of jali seeds as a solid medium for the growth of T. harzianum fungi had a significant effect on the average colony diameter, wet weight, and spore density of T. harzianum fungi. The solid media treatment of 25g of jali seeds gave the best results for the average diameter of the fungus, which was 23.75mm, the difference in media weight was 4.3g, and the spore density was 7.84 conidia/mL
