The research method used is an experimental method with the research design using a Completely Randomized Design (CRD). This research was conducted by giving 6 treatments and 5 repetitions, where there were three parameters used, namely plant height, number of leaves, and plant wet weight. The treatment in question was P0 as (control) without giving kepok banana peel liquid organic fertilizer P1 = 10 ml, P2 = 25 ml, P3 = 50 ml, P4 = 75 ml, P5 = 100 ml kepok banana peel liquid organic fertilizer.
