Abstract

The aims of the research was to determine the perceptions of stakeholders (Community, Government and Employers), to know the potential of mangrove species and determine the impact of mangrove degradation on fish and non-fish biota, at Labuhan Sangoro coastal village. This study was conducted for three months from April to June 2012. Data were analyzed descriptively using a Likert scale for the perception of stakeholders. Potential mangrove species was examined using transects and to determine the impact of mangrove degradation on species diversity of aquatic fauna associated with mangrove were obtained by observation of nonparticipant method. The results showed that perceptions of stakeholders towards preservation and conservation of mangrove land, the 87% strongly agreed, 66% agreed and 22% disagreed, government and employers 86% strongly agree, 78% agree and disagree 3%, but not yet to the application phase. The potential of mangrove type in the coastal village of Labuan Sangoro at Station 1, 2, 3, and 4 by R. mucronata and R. stylosa, Transect I dominated by Rhizophora mucronata, R. stylosa, R. apiculata, Sonneratia alba, Lumnitzera racemosa and Ceriops tagal, transect II by Avicennia marina, R. mucronata and R. stylosa, Transect III by A. marina and R. mucronata and transect IV by R. mucronata and R. stylosa. Fish eatch on the condition of low and high degradation condition, the dominant fish species caught is Beronang (Siganus sp), non-fish species dominated by Crab (Scylla serrata). The number of catches in the low mangrove land degradation conditions wais 2,609 species of fish and non-fish tail 4678, on the high mangrove degradation conditions, the fish catch was 1,090 and non-fish was 1,114. The diversity, uniformity and the dominance of species, classified in the category of low and moderate levels.

Abstract

Coral reef and its life within is a high value natural resources. Management of KKLD GiliSulat-GiliLawas has been going for 8 years, however the management was still not maximal, in particular on preservation of coral reef ecosystem in the conservation area, and community commitment in managing and conserving fish resources and other biota. Therefore, to improve management planning, study need to be done with the aim to find out destruction level of coral reef at KKLD GiliSulat – GiliLawang, based on coverage percentage, fishermen, private sector and government perception. Also to identify policy related with coral reef management in this area, then to formulate its management strategies. Results of the survey shows that in general, average condition of the coral reef in this area is fair (lifeform= 49,26%). Recommended management strategies in KKLD GiliSulat-GiliLawang include SO strategies (Strength - Opportunity) which are coral reef management should be based on ecotourism, increasing community involvement in managing the coral reed and improve institutional strength of KPPL, and maximizing function and task of UPTD KKLD. WO strategies (Weakness - Opportunity) are increasing monitoring, give training on coral reef conservation, improving partnership in management, and increasing quality and quantity of KKLD human resources. ST strategies are (Strength – Threats) socialization of regulation, increasing effective coordination among stake holder, accurate analysis of environmental impact and improve research and sustainable diversification on fishing businesses. WT strategies are (Weakness-Threats) compliance to law, involving all parties in every decision made and making a good coastal areas plan.
