Abstract

This research was conducted to assess the social and ecological resiliences of mangrove ecosystem to sea level rise as a consequence of climate change. Resilience Index (RI) method was used range from 0 to 1. Sixteen resilience indicators, both ecological and social, are selected, developed, and evaluated. The indicators consist of mangrove coverage, density and diversity, aquatic fauna species, tidal flooding, salinity, sedimentation, land use, mangrove dependency and time allocation, conflicts potential, knowledge, the compliance rate, types of livelihood, institution cap, and level of education. Evaluation result indicate that the bay was divided into two categories of resilience; the majority has middle resilience because the mangrove coverage, density, and land use are high, with composite RI (CRI) range from 0.45 to 0.58. This was found in the villages of Muara, Langensari, Blanakan, Jayamukti, and Rawameneng. Only one village has high CRI of 0.69, such as the Cilamaya Girang. The main ecological factors that contribute to the high resilience of the area is the rate of sedimentation of 2 meters per year and rare tidal flooding, while the factor that contributes most to the impediment of social resilience is public knowledge about the importance of mangrove ecosystems©Penelitian ini merupakan penilaian parameter resiliensi ekologis-sosial ekosistem mangrove terhadap penaikan muka air laut sebagai konsekuensi dari perubahan iklim. Analisis yang dilakukan adalah untuk menghitung indeks resiliensi (Resiliency Index/RI) yang menggunakan skala 0-1. Enam belas parameter (ekologis-sosial) digunakan dalam penelitian ini, yaitu: penutupan, kerapatan, keanekaragaman jenis mangrove, jenis fauna akuatik, salinitas, banjir pasang, penggunaan lahan, laju sedimentasi, ketergantungan masyarakat, alokasi waktu pemanfaatan ekosistem mangrove, potensi konflik, tingkat kepatuhan masyarakat, pemahaman fungsi mangrove, jenis mata pencaharian, kelembagaan, dan tingkat pendidikan. Hasil analisis RI menunjukkan, Teluk Blanakan hanya memiliki 2 tingkat resiliensi, yaitu Tingkat Menengah dan Tingkat Tinggi. Tingkat Menengah memiliki penutupan mangrove yang rendah, kerapatan mangrove yang rendah, dan ketergantungan pemanfaatan mangrove yang sangat tinggi dengan kisaran nilai RI 0.45-0.58 yang ditempati oleh Desa Rawameneng, Jayamukti, Blanakan, Langensari, dan Muara. Tingkat Tinggi dengan nilai RI 0.69 hanya ditempati oleh Desa Cilamaya Girang, karena memiliki laju sedimentasi dan ketergantungan masyarakat terhadap kawasan mangrove yang rendah©

Abstract

Erosion rate on corals due to activities of other biota is called bioerosion. The rock-boring urchin, Echinometra mathaei, when it is abundant, plays a significant role in benthic ecosystems, including biological processes like coral erosion. During feeding, E. mathaei erodes calcium carbonate besides grazing on algae living on coral, so it plays an important role in both organic and inorganic carbons in coral reefs. The urchin E. mathaei actively feeds during the night time (nocturnal grazer). Although in Okinawa four types (A-D) of the urchin exist, the research only focused on the types A and B. Type A of E. mathaei produced 0.44951 g feces per day on average while type B produced 0.38030 g feces per day. CaCO3 analysis in feces and gut contents showed bioerosion rate of E. mathaei type A was 0.64492 g/individu/day, and 0.54436 g/individu/day in type B. There were no significant differences in bioerosion impact of E. mathaei type A and B© Laju erosi pada karang yang disebabkan oleh biota, dikenal dengan bioerosi. Bulu babi jenis Echinometra mathaei, ketika melimpah, menjadi sangat berpengaruh terhadap ekosistem bentik termasuk proses biologi seperti erosi karang. Selama aktivitas makan, E. mathaei menggerus kalsium karbonat dalam proporsi yang besar di samping alga yang tumbuh menempel pada karang sehingga memiliki peran penting dalam siklus karbon organik dan anorganik di ekosistem terumbu karang. Bulu babi E. mathaei aktif mencari makan pada malam hari (nocturnal grazer). Meskipun di Okinanawa ada 4 tipe (A-D), pada eksperimen kali ini memfokuskan pada tipe A dan B saja. Tipe A E. mathaei rata-rata memproduksi 0,44951 g feses/hari dan tipe B memproduksi 0,38030 g feses/hari. Berdasarkan analisis CaCO3 yang dilakukan pada feses dan isi lambung, laju bioerosi yang disebabkan oleh E. mathaei tipe A sebesar 0,64492 g/individu/hari sedangkan tipe B sebesar 0,54436 g/individu/hari. Tidak terdapat perbedaan dampak bioerosi yang signifikan antara E. mathaei tipe A dan B©
