Abstract
The production of merang mushrooms tends to decrease from year to year. Some factors that can cause a decrease in mushroom production are the planting media used that are less than optimal in the process of mushroom growth. Planting media from agricultural waste such as blotong and oil palm empty fruit bunch waste. Providing the appropriate planting media will be more optimal if supported by the provision of additional nutrients like tempeh liquid waste. The research was conducted in Mangaran village, Ajung District, Jember Regency, East Java from January to March 2025. The experiment was conducted factorially with the basic pattern of Completely Randomized Design (CRD) and repeated three times. Factor I is a variety of planting media composition consisting of 3 levels, namely J0 (100% straw), J1 (75% straw + 25% blotong), J2 (75% straw + 25% empty palm bunches). Factor II is the concentration of tempe liquid waste which consists of 3 levels, namely K0 (control), K1 (50% tempe liquid waste), K2 (100% tempe liquid waste). The variables observed were harvesting speed, fruit body diameter, number of fruit bodies per harvest, total number of fruit bodies, weight of fruit bodies per harvest, total weight of fruit bodies. The data obtained were analyzed using ANOVA. If there were significant differences among treatments. DMRT was conducted at the 5% level. The best results showed that the treatment combination of media composition of 75% straw + 25% oil palm empty fruit bunches and adding consentration 50% tempe liquid waste.
