Judul: Analisis Kelayakan Usahaternak Sapi Perah pada Alda Alya Dairy Farm di Kecamatan Tambun Selatan, Kabupaten Bekasi
Abstrak: The availability of national milk has not been able to meet the needs of milk, only about 21 persen in 2013. While existing market potential was quite large with the increasing number of population. Alda Alya Dairy Farm took that chance and opened dairy farming on 2007. However, the investments made in the business requires substantial capital investment and a long payback. Therefore,it was necessary to conduct research on the feasibility analysis of dairy cattle farming. The feasibility analysis of dairy farming conducted on the feasibility of financial and nonfinancial. Nonfinancial feasibility was done based on market aspects, technical aspects, management and legal aspects, and social, economic, and environmental aspects. While the financial feasibility was measured by investment criteria such as NPV, IRR, Net B/C, Gross B/C, and Payback Period. In addition, there was a switching value analysis on components of lower sales volume and an increase in feed costs. Based on the results of the analysis of both financial and nonfinancial feasibility, Alda Alya Dairy Farm is feasible to run.And based on switching value analysis Alda Alya Dairy Farm more sensitive to components of lower sales volume.

Judul: Analisis Kelayakan Pengembangan Usaha Peternakan Sapi Perah KUNAK (Studi Kasus Usaha Ternak Kavling 176, Desa Pamijahan)
Abstrak: Milk is one of farm commodities with high consumption level. But, the gap between production and consumption of milk requires us to import from the other country. Furthermore, business developments necessary in order to fulfill the needs of national milk consumption. ‘Kavling 176’ is one of the farm that increases milk production. There for it needs feasibility analysis to ‘kavling 176’. Feasibility analysis is used to determine (1) non financial aspect of the business; (2) business development opportunities of the financial aspect; (3) sensitivity analysis of business. The method used in the financial aspect are Net Present Value (NPV), Internal Rate of Return (IRR), Net B/C Ratio, Payback Period (PBP) and Break Event Point (BEP). Based on the objective, obtained the following result as : (1) business are feasible according to the non financial aspect; (2) business development can be carried out with value NPV Rp 292.514.822,00, IRR 25,93%, Net B/C Ratio 1,42, PBP 2.83 years, and BEP Rp 225.155.564,00; (3) business are sensitive in decrease production of 22% and conditions combined 63%.

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.
