Pineapple and banana are two types of fruits which pulp is used as processed food. Meanwhile, the peels of the fruits may pollute the environment. The purpose of this study is to find alternatives of use of pineapple and banana peel wastes by making liquid organic fertilizer with a natural bacterial starter. This study used an experimental method by making variations in the mass ratio between pineapple peel and banana peel. The first step in producing liquid organic fertilizer is by making starters. After that, organic fertilizer is made based on variations in the ratio of pineapple peels to banana peels and starter. Based on this study, organoleptic test results in the aspect of colour in fertilizer B and fertilizer C obtained were 2.33. The results of organoleptic tests of aroma aspect of fertilizer B recorded was 2.78 and 3.11 for fertilizer C, while the result of the pH test was 4.
