Mangrove Ecosystem Management based on Mitigation for Natural Disaster in Coastal Community

Abdul Haris Sambu, A Amruddin

Abstract

Mangrove trees plantation program is expected to restore a damaged environment. The purpose of this research was to: (1) identify the part of mangrove that serves as disaster mitigation (2) analyze the function of mangrove physical ecosystem in preventing a natural disaster, and (3) analyze economic value of mangrove ecosystem in overcoming natural disaster for the coastal community. The method used in this research are creating the transect the location of observation and analyzing the economic valuation. The results of this study are as follows: (1) roots, stems, branches and twigs that make form a unity as mitigation of coastal natural disaster and small island, (2) mangrove roots consists of various types and cross-shapes vertically and horizontally , other than that the roots, stems, branches, and twigs of mangrove vegetation strong and elastic so it is not easily broken or cut, and (3) the value of mangrove valuation from physical function to overcome natural disasters is about IDR. 6, 075, 892, 844. The suggestion in rehabilitation effort or recovery of mangrove ecosystem should be done semi-natural. Let human only spread the seeds of various types of mangrove on the expanse to be restored its ecosystem as well as let distance and line grow naturally. Rehabilitation result of mangrove ecosystem is expected to reach high diversity level and adaptive to the environment. In addition. let every mangrove seeds grow naturally ensuing the ecological condition.
