Abstract

ABSTRACTSeagrass ecosystem has a function of spawning, nursery, and feeding ground. Besides, it could be used as a bio-indicator of environmental health. This study of seagrass ecosystem was done in 17- 22 May 2014 in Lembeh Island and Tanjung Merah, Bitung. The purpose of the study is to obtain existing condition of seagrass ecosystem and its role as environment bio-indicator. Purposive sampling method was used representing all study sites. Structure analysis of seagrass communities describes the existing condition, while scoring / weighting method estimate current condition of the seagrass. Results that show there are seven species of seagrass. In the stations opposite to Bitung mainland, 75% of the seagrass are Enhalus acoroides (10-50% covers). Importance value index of the seagrass species were Enhalus acoroides (231–300 %), Thalassia hemprichii ( 102–198 %) and Halophila ovalis (110 %) respectively. Based on the weighting method and environmental standard quality, seagrass ecosystem in Lembeh island opposite to Bitung mainland was in damage and unhealthy condition, while seagrass ecosystem opposite to the open sea was in a good and healthy condition. This was due to the domestic waste that is trapped in seagrass ecosystem in the study site. It is necessary to improve awareness to maintain quality of environmental.  Keywords: seagrass, existing, bioindicator, Lembeh Island

Abstract

Kawasan pesisir Desa Sarawet Likupang Timur memiliki mangrove seluas 379 hektar dan me­miliki potensi untuk dikembangkan sebagai kawasan ekowisata. Berdasarkan hal tersebut, penelitian ini bertujuan untuk (1) Menganalisis struktur komunitas hutan mangrove di Desa Sarawet (2) Mengkaji po­tensi kawasan pesisir Desa Sarawet untuk dikembangkan menjadi kawasan ekowisata berbasis mangrove. Hasil analisis terhadap 6 variabel yaitu sumberdaya alam, budaya lokal, sosial-ekonomi masyarakat, in­frastuktur kawasan, institusional dan kemungkinan dampak di kawasan pesisir Desa Sarawet menghasil­kan nilai 3,7. Nilai ini menunjukkan bahwa kawasan pesisir Desa Sarawet berada pada level moderat ya­ng berarti dapat dikembangkan sebagai kawasan ekowisata berbasis mangrove. Kata kunci: Sarawet; ekowisata; mangrove   Coastal village of East Likupang Sarawet has 379 hectares of mangrove area and has the poten­tial to be developed as an ecotourism area. Accordingly, this study aimed to (1) To analyze the community structure of mangrove forest in the village of Sarawet (2) To assess the potential of the coastal village of Sarawet to be developed into a mangrove-based ecotourism region. The results of the analysis on six va­riables, namely natural resources, local culture, socio-economic communities, regional infrastructure, institutional and likely impact on the coastal village of Sarawet produce a value of 3.7. This value indi­cates that the coastal village of Sarawet is at the moderate level wich means it can be developed as a mangrove-based ecotourism area. Keywords: Sarawet; ecotourism; mangroves.
