The study was arranged using a Completely Randomized Design (CRD) with two factors and three replications. The one factor was composition of plant media with three levels i.e. A1 = soil : manure : sand (1:1:1) ; A2 = soil : manure : sand (2:1:1) ; A3 = soil : manure : sand (2:1:2) and second factor was concentration of coconut water with four levels BO = concentration 0% ; B1 = concentration 15% ; B2 = concentration 30% ; B3 = concentration 45%. The results of the study showed the planting media treatment A1 = soil : manure : sand (1:1:1) planting media had a significant effect on seed height and root volume,but the effect was not significant on other parameter. The treatment of coconut water concentration B0 = concentration 0% significantly affect on seedling height and number of leafs, but the effect was not significant on other parameter. The interaction of media composition treatment and coconut water concentration on the growth of araica coffee (Coffea arabica L.) Variety S795 in the parameter of increasing the numer of leafs and increasing the diameter of the stem.
