PENGARUH PUPUK ORGANIK CAIR AIR KELAPA (Cocos nucifera L.) DAN BONGGOL PISANG TERHADAP PERTUMBUHAN TANAMAN TOMAT (Lycopersicon esculentum Mill) SEBAGAI SUMBER BELAJAR BIOLOGI

The growth of tomato plants for its growth requires a source of nutrients, to increase the nutrients in the soil. The solution to overcome this is through fertilization using environmentally friendly organic fertilizers. The use of organic matter as a nutrient in plants is considered good. Organic materials that have not been widely used and tend to become waste are coconut water and banana weevil. Coconut water and banana weevil have the opportunity to be used as liquid organic fertilizer because they contain nutrients needed by plants such as Nitrogen, Phosphorus, Potassium and growth regulators. In this study, tomato plants were used because it is a fruit vegetable that is widely consumed by Indonesian people and has many health benefits. The purpose of this study was to determine the effect of liquid organic fertilizer coconut water and banana hump mole on the growth of tomato plants. This research was conducted from June to July 2022 in Trenggalek. This study was arranged using an experimental design in the form of a 2-factorial Randomized Block Design (RAK) with 3 replications. The first factor is coconut water which consists of 4 levels (A0 = no coconut water, A1 = 25%, A2 = 50%, A3 = 75%). The second factor was banana weevil which consisted of 3 treatment levels (B1=20%, B2=30%, B3=40%). The research data were analyzed using the Two Way Anova test and further tested using the Tukey test or 5% BNJ. The results showed that the treatment of coconut water and banana weevil mole independently and by interaction gave a significant effect on the parameters of tomato plant height. The concentration of liquid organic fertilizer treatment with coconut water was good for plant height at a dose of 50% and the concentration of liquid organic fertilizer treatment for banana weevil was good at a dose of 40%
