Abstract

This research was conducted at the Experimental Station of the Faculty of Agriculture No. Pool Road. 1 Medan Estate Percut Sei Tuan Subdistrict with a height of 12 mdpl flat topography, alluvial soil type and soil pH 5 - 7. The research was conducted on 25 October 2018 to 25 January 2019. This study used a Factorial Randomized Group Design consisting of 2 treatment factors, namely: 1) Factors of coffee skin compost (K notation) consisting of 4 treatment levels: namely K0 = Without coffee skin compost, K1 = Coffee skin compost 1 kg / m2, K2 = Compost of coffee skin 1.5 kg / m2, K3 = Coffee skin compost 2 kg / m2. 2) Giving POC fish waste (P notation) which consists of 4 levels of treatment namely: P0 = Without POC fish waste, K1 = using POC of 250 ml / L water waste, P2 = POC fish waste 500 ml / L water, P3 = 750 ml / Lair POC of fish waste. The parameters observed in this study were Plant Height, Number of Branches, Number of Pods per Sample, Number of Pods per Plot, Weight of Pods Containing Per Sample, Weight of Pods Containing Per Plot and Total Production Per Ha. The results obtained from this study, namely 1). The application of coffee skin compost affected plant height, number of branches, number of pods per plot and weight of pods per plot. In this case the provision of coffee skin compost at a dose of 2 kg / m2. 2). The administration of fish waste POC significantly affected plant height and number of pods per plot. In this case the provision of fish waste POC with a concentration of 750 ml / L water. 3). The combination of the administration of coffee skin compost and POC of fish waste is not real to the growth and production of peanut plants.
