Abstract

Mangroves are renewable resources that provide services related to the environment, such as abrasion protection, reduction of the height and speed of ocean waves, cleaning of water contaminants, which are essential to support living beings. Research objective to study and evaluate the impact of planting distance from the beach that is useful to increase the growth of mangrove Rhizophora apiculata, This study used a randomized Block Design (RAK) consisting of 5 treatments with 6 replications. The treatments were planting distance with P0 = 41 meters, P1 = 42 Meters, P2 = 43 Meters, P3 = 44 meters and p4 = 45 meters. From the observation of seedling height, seedling diameter, leaf length, number of leaves, leaf width, wet weight and dry weight it can be concluded that the spacing treatment does not affect plant growth and can be expressed as insignificant.
