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

Daerah Biduk-biduk merupakan bagian dari 285.266 ha kawasan konservasi laut daerah Berau. Lamun merupakan salah satu ekosistem pesisir yang dapat dikaitkan dengan keberadaan penyu dan potensi sebagai penyimpan karbon pesisir. Penelitian ini dilakukan dengan metode survei, studi literatur dan analisis di laboratoraium. Kondisi eksisting lamun yang ditemukan dengan indeks nilai penting (INP) jenis Halophila ovalis (Ho) di P Kaniungan Besar dan Halodule pinifolia (Hp) di Teluk Sulaiman merupakan lamun berukuran kecil yang membentuk hamparan. Stok karbon pada  biomasa lamun sebesar 2,11 kgC/ha setara dengan penyerapan 7,74 kgCO2e/ha. Ekosistem lamun yang berukuran kecil membentuk hamparan menunjukkan jenis lamun yang tumbuh rapat dan merupakan makanan bagi penyu dan biota lainnya. Keberadaan rhizoma lamun akan menjaga stok karbon sedimen dan membuat  sedimen menjadi stabil. Produksi perikanan di Kecamatan Biduk-biduk meningkat 7,7 % sejak tahun 2010 sampai 2014. Sehingga diperlukan menjaga keberadaan ekosistem lamun di Kecamatan Biduk-Biduk khususnya dan Kabupaten Berau pada umumnya agar keberadaan penyu dan layanan ekosistem lamun terpelihara dengan baik.
