Judul: Vurnerability of leatherback population analysis (Dermochelys coriacea Vrandelli 1761) in jamusrba medi and wermon beach as indicator of sustainability of abun marine protected area Tambrauw Regency, West Papua
Abstrak: Decline of leatherback population in Jamursba Medi and Wermon beach in the last 10 years, has impact stock leatherback populations in the Western Pacific. Environmental and social antropogenic factors were be fathomed on population decline, especially the number of individuals and the number of new individual adults. This study aims to determine the status utilization of leatherback populations, vulnerability index, and recommendations in the implementation of best management scenarios sustainability Abun marine protected area as protection of the leatherback habitats and these population. Result explicates that currently these status has categorized in endangered and be beased non determental finding reveals that utilization of leatherback does not lead to sustainability. Composite performance of these vurnerable index framing in Jamursba Medi is at the level of medium vurnerable (0.486) and Wermon is at the level of high vurnerable (0.616). Social influences of anthropogenic be one of the greatest threats to the environment in addition to population decline. The threat is indicated by the high activity of egg collection, hunting the adults of the community within and outside marine protected area, as the north sea islands, Manokwari and Southeast Maluku. In addition to direct use of bycatch from commercial fisheries are also factors leatherback population decline. Furthermore, directly use through co-catching from comersial fishery operations was also be a decreasing factor of leatherback population. Based the results it is recommended several scenarios through tradeoff analysis approach. Both of sub model environmental integration and social antropogenic scenarios are selected and considered as the best with the quality value of 66.03. It are which in turn encouraged in sustainable implementation of Abun MPA.

Judul: Evaluasi Pengelolaan Terumbu Karang di Kawasan Konservasi Laut Daerah Pulau Biawak dan Sekitarnya Kabupaten Indramayu Provinsi Jawa Barat.
Abstrak: The research was conducted in Marine Conservastion Area of Biawak Island of Indramayu, West Java Province. The Marine Conservastion Area is located in the Java Sea, northern part of the Indramayu District which familiar with high pressure from fishings, industries, and other human activities. The objective of the research were to assess condition of coral reefs, to assess role and importance of key stakeholders in the coral reef management and to evaluate current its management and recommend to better coral reef management in the area. I employed Line Intercept Transect, Visual Cencus Methods, Reef Check Benthos, Household interview and Expert interview to collect biophysical and socio-economic data. Coral reefs condition categorized as bad to medium condition with percent coral cover variated among 22,7±5,9% to 45,7±13,2%, 13 families and 39 genuses were found. The density of reef fishes were variated among 5.967±1.767 ind/ha to 20.433±10.355 ind/ha with 85 species and 18 families and the density of benthos were variated among 2.000±1.000 ind/ha to 14.667±14.964 with 29 species and 23 families. Result showed that anthropogenic activities gaves high pressure on coral reef condition. Destructive fishing still practiced around the protected area. Law enforcement, surveillance and monitoring actions were not implemented well. Government institution and private sectors need to be collaborated to create good coral reefs management. Collaboration among stakeholders became the key to successful MPA management. Implementation of management policy need to be focused on protect and conserve coral reefs to restore the condition.
