Abstrak: Ornamental fish is one of the new commodity that still require more intensive development efforts in Indonesia. Iwan Wahana Fish Farm as a business entity engaged in the field of cultivation of freshwater ornamental fish have not been able to meet the demand against the increasing every year, so it will be done to expand the scale of business development. The purpose of this research is to analyze the feasibility of the development of freshwater ornamental fish Iwan Wahana Fish Farm in Bekasi based on market aspects, technical aspects, and financial aspects. The analysis tool used are the TOWS analysis, EOQ method, NPV, Net B / C, IRR, Payback Period, and Switching Value Sensitivity analysis supported by Microsoft Office Excel software. As a result, market aspects and technical aspects of business development declared eligible to run. On the financial aspects of business development at Iwan WahanaFish Farm feasible with NPV of Rp 377 989 000; Net B / C of 2.29; IRR of 46% and payback period for 1.5 years. The results of the sensitivity analysis calculation of switching values obtained maximum changes decrease the survival rate of freshwater ornamental fish by 48.98%, the maximum change in market demand decline of 24.82%, and the maximum change for the increase in raw material costs amounted to 51.55%.

Abstrak: Pomfret fish hatcheries highly prospective based on farmers' demand for seed by farmers is likely to increase due to high levels of fish consumption. The purpose of this study was to analyze the feasibility of developing the business development of freshwater pomfret fish hatchery at Ben's Fish Farm. Research methods by assessing ranging from non-financial aspects ie market aspects, technical aspects, management aspects, and social aspects and management, in addition to non-financial aspects of the financial aspects are also assessed using the Business Feasibility Study. From this research, look at every aspect of the components that are important then Business Development Hatchery In Ben's Fish Farm Company may consider appropriate to do.

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.
