Judul: Analisis Efisiensi Pemasaran Anggrek Potong Vanda douglas di Desa Rawakalong, Kecamatan Gunung Sindur, Kabupaten Bogor
Abstrak: Vanda douglas Orchid has a good business prospect in Bogor, but its farmer’s share is relatively low. The aim of this study that is conducted in Rawakalong Village is to identify the efficiency of marketing system. This research used both qualitative and quantitative marketing analysis. The method used to select the respondents was purposive sampling with total result 20 people. The method used to select the marketing institutions was snowball sampling. The result showed that there were 4 marketing channels formed with different channels, institutions, functions, and market conduct. Three parameters that were used on the marketing operational efficiency analysis were the sum of marketing margin, farmer’s share and benefit-cost ratio which showed that channel IV (farmers wholesaler consumers) was relatively more efficient.

Judul: Analisis Pendapatan dan Pola Pemasaran Usahatani Anggrek Vanda douglas (Studi Kasus: Petani Anggota dan Non Anggota "Gapoktan Bersatu" Desa RAwakalong, Kecamatan Gunungg Sindur, Kabupaten Bogor)
Abstrak: Ornamental plants / floriculture has good prospects because each year shows an increase in demand for ornamental plants, especially in orchids. According to the Central Bureau of Statistics (2014), there are three biggest contributor orchid production in Indonesia, West Java, Central Java and Banten. Gapoktan Bersatu is one of achievement gapoktan in Indonesia engaged in farming Vanda douglas located in Rawakalong village, District of Gunung Sindur, Bogor Regency. Rawakalong village is one of the main Vanda douglas production areas in West Java. The purpose of this study is to identify and compare the characteristics of the farm, traders, institutions and marketing channel, revenue and marketing patterns of Vanda' doi/glas 'farming' beiwee'n . members and non-mem'bers of Gapoktan Bersatu Rawakalong Village, District Gunung Sindur, Bogor Regency. The results of the analysis of revenue, RIC ratio on cash costs and total costs and BEP shows that Vanda douglas farming of gapoktan non members are more profitable than Vanda douglas farming of gapoktan members. Vanda douglas farming of gapoktan non members scale II are more profitable than other's. Results of the analysis on the marketing pattern showed that Vanda douglas marketing channel III of gapoktan non members (farmers to wholesalers to consumen) is the most efficient marketing channel because it has the lowest marketing margin and the highest farmer's share value. In order to obtain the most efficient Vanda douglas marketing then the channel III of gapoktan non members advised to apply.

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.
