The drip hydroponics system has a weakness which at a high evapotranspiration condition can’t fulfill plant water requirement properly. Improving the composition of plant growth media with cocopeat and rice husk charcoal is a solution to increase Kailan Plant Growth. This research aims to study the effect of a ratio between cocopeat and rice husk charcoal as plant media to increase productivity of Brassica oleraceae on drip hydroponic. The research was conducted at Jatinangor-Sumedang-West Jawa from November to December 2017. The method of this research used completely randomized design with five treatment (A=Cocopeat 100%; B=Cocopeat 75%+ Rice Husk Charcoal 25%; C = Cocopeat 50% + Rice Husk Charcoal 50%; D = Cocopeat 25% + Rice Husk Charcoal 75%; E = Rice Husk Charcoal 100%), and five replication. The growth indicator in this research is plant height, number of leaves, leaf area, fresh plant weight, and shoot-root ratio. The ratio of cocopeat and rice husk charcoal as plant growth media affect the plant growth of kailan. The result showed that composition grows media Cocopeat 75% + Rice husk charcoal 25% affect plant height, fresh plant weight, and shoot-root ratio. The plant grow substrates with good aeration and water holding capacity can improve Kailan plant growth on drip irrigation system.
