Judul: Analisis Pendapatan dan Kelayakan Usaha Akar Wangi di Kecamatan Samarang Kabupaten Garut
Abstrak: Vetiver is one of plantation sub-sector with a huge potensial to be developed which have share of the world market at a price level is quite high. The subdistrict Samarang is one of vetiver production centers located in Garut district of West Java Province. Vetiver farming in the District of Samarang has the potencial to earn huge profits, because the area has the land and the weather is suitable for the cultivation of vetiver. But in 2013, the vetiver farming in Garut decline in production which resulted in the revenue of vetiver business decreases. The purposes of the research are to analyze the performance of vetiver and to analyze income and feasibility of businesses vetiver The result of the study showed that the farmers and refiners have not implemented appreciate cultivation and distillation techniques Good Agriculture Proccessing (GAP) and Good Maifacturing Practices (GMP). Business actors vetiver consists of farmer, distiller, farmerdistiller, farmer-distiller-gatherer and farmer-distiller-gatherer-exporter. The result of the study showed that the highest income bussines acquired by farmerdistiller- gatherer-exporter and the lowest income earned by farmers alone business. Business of vetiver is feasible. Based on the result of the sensitivity analysis, a decrease of vetiver prices, a decrease of vetiver oil prices, an increase fuel prices and an increase of export costs can decrease revenue and unfeasible business of vetiver. Use of quality seeds, an increase production and an increase capacity of raw materials can increase revenue businesses vetiver.

Judul: Perbaikan Teknik Produksi dan Analisis Kelayakan Finansial Usaha Produksi Minyak Akar Wangi (Vetiveria zizanoides) di Kampung Legok Pulus Kabupaten Garut
Abstrak: Vetiveria zizanoides commonly known as vetiver is a kind of essential oil that has large marketing opportunities. Haji Ede home industry is one of the vetiver root oil producers that located in Kampung Legok Pulus, Garut. The purpose of this research is to formulate the improvement of production method and to analyze the financial feasibility of vetiver root oil production. The suggested improvement were formulated on the process of harvesting, drying, and distillation. With 10-year investment value of Rp 200,000,000, investment of complement tools each year amounting to Rp 429,000, fixed costs of Rp 27,188,000/year, the variable cost of Rp 1,996,457,500/year, the unit cost of producing oil vetiver is Rp 766,600/kg. The BEP 2,530 kg/year. As the selling price is Rp. 800,000/kg, the profit obtained by UKM vetiver oil refinery is Rp. 88,176,000/year. The NPV of Rp 213,508,492, Net B/C of 3.27, Gross B/C 1.02, IRR 36.17%, and payback period for the past 2 years and 6 months indicate that the business is financially feasible.

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.
