Pemanfaatan Cocopeat sebagai Media Tumbuh Sengon Laut (Paraserianthes falcataria) dan Merbau Darat (Intsia palembanica) (The Utilization of Cocopeat as Growing Media for Paraserianthes falcataria and Intsia palembanica)

Abstrak

Rising urban development decreased the availability of topsoil for growing media. Therefore, it was necessary to study potential alternative media such as cocopeat. The objective of the study wasto know the optimum composition of cocopeat and soil for optimum growth of Paraserianthes falcataria and Intsia palembanica. The method used was a complete random design. Five treatments were applied to each seedling, included: A (100% soil), B (75% soil + 25% cocopeat), C (50% soil + 50% cocopeat), D (25% soil + 75% cocopeat) and E (100% cocopeat). Seedlings growth were analyzed using analysis of variance, followed by least significant different (LSD) test. Result showed that the 25% cocopeat compound was the most optimum composition for Intsia palembanica seedlings, while 25% and 50% of cocopeat composition was the most optimum for the Paraserianthes falcataria growth.
