Abstrak: Marine protection area (MPA) program head for to protect marine resources and increase fish production. The program is involve the active participation of the community at every stage. The purpose of this study are: (1) describes the DPL activity arrangement program, the knowledge of fishermen, and the fishermen's socio-economic status, (2) analyze the relationship between DPL activity arrangement program, fishermen knowledge, and socio-economic status of fishermen by fishermen participation in the DPL program, (3) describes the efforts that can be implemented to increase participation in the DPL program. This study was conducted using quantitative and qualitative. The results of this study indicate the participation of the fishermen in the stages of the determination of DPL is classified low because fishermen rarely participate in various activities. The participation in the observance of fisherman’s rules stage dpl is classified high. All fishermen do not violate the rules. The participation of fisherman in the monitoring stages is classified moderate. Most of fishermen took part on monitor the DPL areas such as attention fishermen or people who are around DPL as well as reprimand and report in case of violation.

Judul: Strategi pengembangan partisipasi masyarakat dalam pengelolaan areal perlindungan laut berbasis masyarakat di Kabupaten Administrasi Kepulauan Seribu, DKI Jakarta
Abstrak: In the last two decades, coral reef ecosystem in Kepulauan Seribu has shown a significant degradation. Coral reef ecosystem condition was considered as poor to fair with average live coral cover of 32,69 % in 2004, while in 2007 it was reduced to 31,33%. Rapid development, population increase and climate change are threatening coral reef resources, while communities continue to seize potentials in using or modifying resources for their livelihood and welfare. Starting in 2004, the local government established Community Based–Marine Protected Area (CB–MPA) in village of Panggang Island, followed by other four villages within the Kepulauan Seribu District. It is expected that co–management approach may encourage community responsibility over activities affecting coral reef ecosystem and natural resources. Sharing of responsibilities and authorities between local fisher community and government should emphasize on the community participation in CB–MPA management. Community participation in CB–MPA management in Kepulauan Seribu is considered unsatisfactory due to interactions of several factors. Given this fact, the objectives of this research are as follows: (1) to analyze fisher community participation in managing CB–MPA in Kepulauan Seribu and (2) to analyze the determinant factors influencing community participation in managing CB–MPA in Kepulauan Seribu and (3) to design strategy of community participation improvement in managing CB–MPA in Kepulauan Seribu. This study showed that level of community participation in performing co–management of CB–MPA in Kepulauan Seribu was low and passive throughout all participation phases. Factors affecting low community participation were indicators related with community organization ability, ranging from managerial, social and technical ability; also related with low community motivation, that are motivation to conserve the resources, raise income and gain credibility acknowledgement. The lack of community organization ability and community motivation was influenced by quality of CB–MPA management where indicators related with compatibility of program conception, program communication approach and intensity of extension agent roles. Managerial ability representing by community organization as CB–MPA facilitators was considered as the most significant indicator affecting the low community participation. Community organization plays important role during the process of co–management, however community organization is duty–bound to build their managerial capacity and independency. Both conditions are prerequisites for upholding role of community organization as primary facilitator in CB–MPA program implementation. The other indicator was social ability, that is ability to elaborate constructive interaction between different community groups and with other stakeholders from different background or institution. The findings showed the managerial and social ability of community organizations in managing CB-MPA were low. Awareness in conserving natural resources was the most significant indicator affecting community motivation to participate in CB–MPA management. This factor related to emotional bond between the community who yield benefits from the environment with existing resources. The second indicator of community motivation with positive influence to community participation was to raise income. Most of community groups in Kepulauan Seribu are dependent on the existence of natural resources as primary support which secure their economic and domestic needs. Maintaining natural capacity of fishery–marine resources will secure the source of livelihood for Kepulauan Seribu community, thus may develop as motive to secure the source of income. Low quality

Judul: Solusi Geometri Schwarzschild untuk Dimensi 4+1 dengan Invarian Rotasi Isotropik.
Abstrak: Metrik Schwarzschild merupakan solusi eksak pertama dari persamaan medan Einstein dengan mangasumsikan metrik statik dan simetris. Metrik Schwarzschild yang ditemukan oleh Karl Schwarzschild masih dalam dimensi 3+1, namun seiring dengan teori-teori terbaru yang menunjukkan bahwa alam semesta tidak hanya di dimensi 3+1. Maka melalui penambahan dimensi, tujuan penelitian ini memperoleh solusi pada geometri Schwarzschild untuk dimensi 4+1 dengan memodifikasi koordinat bola yang invarian rotasi isotropik dan melalui penurunan rumus seperti koordinat bola, simbol Christoffel, dan tensor Ricci. Selain mendapatkan solusi ini, metrik Schwarzschild dimensi 4+1 dapat digunakan sebagai metrik dasar untuk memperoleh solusi blackhole dan wormhole pada dimensi 4+1. Hasil akhirnya, dengan memanfaatkan modifikasi koordinat bola, metrik Schwarzschild dapat dibentuk sehingga diperoleh solusi geometri Schwarzschild untuk dimensi 4+1.
