Abstract: The research to determines yeast concentration effect and fermentation time of barangan skin waste (Musa acuminata colla) against bioethanol level and produce a learning module design of senior high school in conventional biotechnology material. The experimental research by conducting combination experiments of yeast concentration are 6 grams, 8 grams, 10 grams, and 12 grams which are combine with 72 hours, 120 hours, 128 hours, and 216 hours. The experiment was carried out with 4 treatments and 3 replications where the substrate was hidrolized by sulfuric acid (H2SO4) 0,5 M and continued with the development of learning module from experimental research data (only at the analysis and design stages). The research data were analyzed by analysis of varians (ANAVA) and continued by the Tukey test on 5% level. The results showed that yeast concentration and fermentation time had a significant effect on bioethanol levels but had no effect on the interaction value. Bioethanol content average highest in yeast concentration of 12 grams is 19,81% and fermentation time of 168 hours is 19,37%. All research data can be used for designing learning modules on conventional biotechnology material using project based learning. However, before the module design was used on a large scale advisable to test the feasibility and effectiveness test on a small scale.Key Word: Yeast Concentration, Fermentation Time, Barangan Skin Waste, Bioethanol, Learning Module

Abstract

Abstract : Kepok banana skin waste is organic waste that has not been managed properly. Management of kepok banana skin waste can be used as Liquid Organic Fertilizer (POC). To see the macro nutrient content, namely N, P and K on the POC kepok banana skin, an analysis of the content of N, P and K. was applied. The application of POC was applied to lettuce plants (Lactuca sativa). This study aims to determine the optimal concentration of POC kepok banana skin based on the content of N, P and K and to determine the optimal concentration of POC application of kepok banana skin to lettuce plants. This research uses a quantitative approach with two types of research Complete Completely Randomized Design (CRD). The results showed that without the addition of EM4 it had shown the highest mean for testing the content of N, P and K and its application to lettuce plants. It was concluded that the optimal concentration without addition of EM4 from kepok banana skin waste used as POC based on the content of N, P and K was at treatment K1 and there was the addition of EM4 in treatment K5. The optimal concentration of giving POC kepok banana skin without the addition of EM4 to lettuce plants (Lactuca sativa) was in treatment I1 and without the addition of EM4 was at treatment I5.Key words : Kepok Banana Skin Waste, Effective Microorganism 4, Molasses and Lettuce Plants
