Abstrak: Mangrove forest as unique ecosystem supports an important life in coastal area,and has ecological functions as nutrient supplier for its biota, place for spawning and nursery ground, coastal abrasion buffer, protect from hurricane and tsunami, waste absorber, salt water intrusion defender and others. Besides, mangrove forest has high economic values like as wood and herbal produc tions, fisheries catchments etc. Farther, mangrove forest as habitats for various bird, reptile, mammals other and wildlife, it provides a rich biodiversity and genetic pool this supporting life system. Mangrove protects water quality, absorb CO2 and produce O2 higher than other type of forest. Mangrove has high ecological function and economic value that give benefit for local community requirement. To increase and preserve biological and ecological function of mangrove forest need rational approach. Empang parit system provide application alternative of sylvofishery estimaties of economic value needed for managing mangrove forest to give sustainable benefits for its community. Base on calculation and analysis of its which pattern 80% forest and 20% fishpond in Kecamatan Logonkulon, Kabupaten Subang give highest economic result. Its parameter use Return Cost Ratio analysis (R/C), Return of investment, profit and Break Even Point (BEP) Keyword : Mangrove forest, empang parit , analysis of finansial, usahatani,

Judul: Analisis Finansial Pengushaan Tambak Tumpang Sari Sistem Empang Parit di Kawasan Htan Mangrove (Kasus di Desa Jayamukti, Kecamatan Blanakan, Kabupaten Subang, Propinsi Jawa Barat
Abstrak: Mangrove forest has had very imporant rules in our lifr,not only from the ecologic side, but also from the economic side. since Japan colonialism in Indonesia the destruction of mangrove forest in Indonesia had kept on increase up to now, including the destruction in "pantura" way or called North Coast way. The destructtion of mangrove ecosystem not only caused reduction of mangrove area also caused the decrease of its quality. Considering how very important the mangrove forest motivated me to think how to prevent the damage and made the green revolution for the mangrive forest. According to the thought of making green revolution become successful, so it has been developed that this program involved all the citizens around the which called Community Based Forest Management (CBFM) in hooks silvofishery ponds. This research is meant to analyze the using of mangrove forest are financially as a pond area, so we could know that has been occured, which was arranged to combine the ecology and social economic aspect in human life.

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
