Abstrak: As one of bio-pharmaceutical plant, gotu kola (Centella asiatica) has many potencies, not only from health aspect but also from economical aspect. The high demand for raw material of pharmaceutical industries contributes a high market prospect for gotu kola to expand locally particularly in Bogor. This research aims at designing a business plan of gotu kola leaves processing through the selfmanaged cooperative entrepreneur approach. Cooperative entrepreneur build high motivation of farmer to produce gotu kola by offering highest price. The highest price is due to product as well as market development. This research used the method of quantitative and qualitative data analysis. Quantitative analysis method was used in developing financial planning of the business operation. Business financial report projection of this gotu kola processing and packaging smallholder industry were: Net B/C ratio 2.6 and gross B/C ratio 1.1, and 67% in IRR (Internal Rate of Return). From the financial projection can be concluded that the business was capable to provide a high benefit as well as the farmers’ income increase.

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.
