Melon (Cucumis melo L.) is very popular with the public because the fruit has a sweet taste and high water content. One of the problems in cultivating this plant is that the nutrient requirements of melons are very high. In dealing with nutrient needs, farmers generally use inorganic fertilizers. One effort to reduce the side effects of using inorganic fertilizers is to use organic fertilizers. The cause of this examine turned into to determine the impact and the best treatment for single and combined factors in the used of baglog oyster mushroom waste compost and tofu waste liquid organic fertilizer. The experimental design used in this study was a two-factor Randomized Block Design, which consisted of twelve treatments and was repeated three times to obtain thirty-six experimental units. Each experimental unit consisted of 2 polybags, so there were 72 polybags. B0=No compost, B1=20 ton.ha^-1, B2=25 ton.ha^-1, B3= 30 ton.ha^-1, P0=No liquid organic fertilizer, P1=200 ml.plant^-1, P2= 400 ml.plant^-1.
