Abstract

This study aims : (1) to analyze the status of coastal ecosystems, (2) to analyze factors that affect the quality of coastal ecosystems, and (3) to prepare the direction on spatial planning in coastal areas of Ambon Bay Area. The analytical method used in this study is the analysis of ecosystem status, principal components analysis, analysis of Geographic Information Systems (GIS) and analysis of dynamic systems. The results showed that the condition of ecosystem status damaged in 2008, whereby, the status of mangrove ecosystems is moderate with a density of 1100 trees/ha, the status of seagrass ecosystems damaged by percentage cover of 38,76%, and the status of coral reef ecosystems are damaged by the percentage of live coral is 42,27%. Ecosystem conditions in Ambon Bay Area is affected by land use on land, namely forest area and population. Refferral of land use planning in Ambon Bay Areas wich recommended in this study for a period of 20 years of protected areas and cultivated areas. Protected areas is aimed at 9.480,70 ha or 41,21% of land area, while the allocation of space for the cultivation area is 10.416,30 ha (58,79% of land area). To reduce the pollutant into the waters, planned buffer zones (coastal and riverine border for 11,69% of land area), which serves to absorb pollutants and protect the inland waters of the tidal influence, while still controlling the waste coming into water By using dynamic systems analysis, created the scenario of land use planning in Ambon Bay Area that integrates land and wet land. The scenario used in this study is the optimistic, pessimistic and moderate scenarios. The variable that is used to determine of policy scenarios spatial planning based on the rate of population growth is 2,5% per annum, while variable forest area of at least 30% of the area. Of the three scenarios, the scenario chosen for the land use planning policy in Ambon Bay Areas in the future is to use the moderate scenario. The simulation results moderate scenario, the status of coastal ecosystems is improved from the criteria of the coastal ecosystem damaged by coastal ecosystems index 44,44% in 2008 turned into good condition with the index of coastal ecosystems 88,89% in 2029

Abstract

Kebijakan konservasi penyu dilakukan dengan menetapkan beberapa habitat peneluran penyu sebagai kawasan konservasi. Kawasan konservasi penyu Pangumbahan merupakan salah satu kawasan konservasi penyu di Pulau Jawa. Tingginya tingkat ancaman yang dihadapi oleh konservasi penyu memerlukan peran multistakeholders yang terpadu. Oleh karena itu, kegiatan konservasi penyu memerlukan analisis stakeholders untuk mengetahui kepentingan, nilai penting, pengaruh, dan hubungan berbagai pihak yang berkepentingan dalam pengelolaan konservasi penyu. Penelitian ini bertujuan untuk mengidentifikasi, mengkategorisasi dan menyelidiki hubungan diantara stakeholders, serta merumuskan strategi untuk meningkatkan peran stakeholders. Pemilihan responden dilakukan dengan metode snowball sampling. Pada umumnya stakeholders lebih banyak terlibat pada kegiatan pemanfaatan, yaitu sebanyak 17 stakeholders, sedangkan keterlibatan stakeholders terendah terjadi pada kegiatan pengawetan, yaitu 8 stakeholders. Adapun kegiatan perlindungan melibatkan 14 stakeholders. Hubungan stakeholders yang terjadi meliputi hubungan konflik dan komunikasi. Untuk meningkatkan tujuan pengelolaan konservasi penyu, keterlibatan stakeholders perlu ditingkatkan melalui pemberdayaan masyarakat, peningkatan kegiatan kerjasama dan peningkatan peran serta masyarakat

Abstract

Sea grass bed is an important ecosystem in coastal areas and small islands which plays important and effective roles as a protector of the coastal line and the safety of the mainland area of small islands. Physically, the roles of ecosystem were as erosion prevention, sediment trap and barrier of waves and currents. The existence of these ecosystems in the coastal regions and small islands was an important in enhancing the adaptive capacity of islands against natural disaster because the island serves as a natural protector. The aim of this research was to calculate and assess tha adaptive capacity of sea grass ecosystems growing in the waters of around the small islands in the group of Guraici. The research was conducted on 17 islands located in the group of Guraici islands. Measurement of adaptive capacity of sea grass ecosystem was done by analyzing 6 parameters, namely: Sea Grass Dimension Index (IDLn), Dominant Species of Sea Grass, Sea Grass Coverage Percentage (%), Number of Sea Grass Species, Substrate Type, Distance from The Point of Ecosystem. Sea Grass ecosystem adaptive capacity value was in the range between 0.0-1.0, with capacity of five categories of “very low, low, medium, high and very high”. These results indicated that sea grass ecosystem growing in the waters of around the islands in the island of group Guraici had adaptive capacity with values ranging between 0.0-0.59. The ranges of values were distributed into three categories of the adaptive capacities (very low, low and medium). A total of 13 islands had a capacity of sea grass ecosystem “medium”, the other three islands with capacity of “low” and one island with a capacity of “very low”.    Key words : Adaptive Capacity, seagrass ecosystem.

Abstract

Penyu hijau (Chelonia mydas) adalah spesies yang terancam, termasuk dalam daftar IUCN dengan kategori spesies yang terancam punah, dan termasuk dalam Appendix I dalam CITES yang berarti dilarang diperdagangkan secara internasional. Suaka Margasatwa Cikepuh yang terletak di Kabupaten Sukabumi, Jawa Barat, adalah salah satu tempat konservasi di mana penyu hijau seringkali bertelur. Tujuan dari penelitian ini adalah memberikan data dasar yang berguna tentang ekobiologi penyu hijau dan memeriksa faktor-faktor lebih lanjut yang mengancam populasi mereka. Pengamatan temporal dilakukan setiap tahun sejak 2014 hingga 2018 dengan mengukur kondisi fisik pantai dan kondisi morfologi penyu hijau. Hasil yang diperoleh dari pengamatan di setiap tahun menunjukkan perbedaan dalam total penyu bersarang di kedua pantai. Pada tahun 2014, rasio penyu yang mendarat baik di Citirem - Hujungan diperoleh sebanyak 15:1 (111,5 ± 1,64: 117 CCL / 97 ± 0,36: 101CCW) , sedangkan pada 2018 adalah 4:0 (103.75 ± 2.32: - CL / 93.75 ± 3.92: - CCW). Pantai Citirem ditumbuhi banyak jenis tanaman pantai seperti Pandanaceae, sedangkan di pantai Hujungan, tanaman ini tidak tumbuh luas. Faktor-faktor pengancam penyu hijau yang berada di Suaka Margasatwa Cikepuh sebagian besar adalah aktivitas antropogenik dan factor predasi. Ini perlu menjadi sorotan penting bahwa konservasi penyu perlu dilakukan oleh para pemangku kepentingan yang terintegrasi untuk membentuk manajemen yang baik.
