Judul: Strategy for Small Dairy Farms Development in Cisarua, Bogor
Abstrak: Dairy farms in Indonesia have a good prospect to be developed because more than 70% of national consumers needs are fulfilled from imports. Bogor regency has opportunity to take part in dairy industries by improving dairy farms development in some regions, one of these is Cisarua. This theses describes the sustainable development strategy of small dairy farms in Cisarua. The research was conducted during December 2010 and March 2011 in Cisarua, Bogor, West Java. The informations were collected through indivial interviewed with 28 dairy farmer households and some key informans. The data were analized and presented descriptively. Results showed that the following are possibly happen in development of small dairy farms in Cisarua: (1) decreasing natural fodder carrying capacity which is currently in very critical condition with 0.78 Carrying Capacity Index, (2) increasing of organic pollution in Kali Citeko Bawah, current value of COD (194.2 mg/l) and BOD (86.2 mg/l) are already above the quality standards stated in Government Regulation of Republic of Indonesia Number 82, Year 2001 on air quality management and water pollution control, (3) waste from dairy farms can potentially trigger a social conflict, and (4) farmers do not have any bargaining power in milk selling-price as due to high dependence to Milk Processing Industry. Based on analysis of current conditions in dairy farms and expert opinion, there are several targets to be achieved in order to improve dairy farms development in Cisarua i.e. (1) increase farmers’ income; (2) create employment oppurtunities; (3) optimize natural resource potential; (4) increase local economic growth; (5) to raise public nutrition level; (6) to create zero waste dairy farms and; (7) make dairy cattle as an icon of Cisarua. Analytical Hierarchy Process (AHP) on experts’ choice showed that improvement in quality and quantity of milk/product (0.244), extension in capital access (0.208) and increase human resources quality (0.196) were the major strategies to achieve the targets of sustainable dairy farms in Cisarua, Bogor.

Abstrak: The goals of this research were : 1) to identify internal and external environmental factors which can influences the progress of dairy cattle business, 2) to formulate alternative development strategy and to decide the priority development strategy of dairy cattle business in Sukaresmi, SubDistrict of Cianjur. This research was carried out from Desember 2008 to January 2009. This research used primary dan secondary data. The data was analysed with descriptive analysis and three stages formulating analysis (input stage, matching stage, and decision stage). The result of input stage analysis show that total IFE matrix score is 2,615 and total EFE matrix score is 3,164. This condition place dairy cattle business in Sukaresmi, SubDistrict of Cianjur on sel II (Grow and Build) at matrix InternalExternal (IE). While, SWOT analysis produce five alternatives development strategy, which then analyzed by matrix QSP to decide the priority of the development strategy. Based on matrix QSP, the priority development strategy of dairy cattle business in Sukaresmi, SubDistrict of Cianjur is increase the business scale, develope the product diversification in farmer level, increase capital resources, improve dairy cattle management, and strengthen the function of farmer group.

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.
