Abstrak: One important aspect of post-harvest handling of rice is rice milling. Although many rice milling unit, but deployment and their feasibility has not so optimal.This situation requires an evaluation and needs analysis to assess the optimum level making it feasible to operate profitably. The research objective is to create a cost analysis and feasibility of rice mills and to make sensitivity analysis on several conditions. The study was conducted for 3 months, from May 2010 until July 2010. Using Mr Kardi’s rice milling unit as an objects for the research where located at Situ Gede Village in West Bogor. Based on the calculation of the cost analysis, obtained total cost rice mill for a year is Rp. 37,033,093.194. Main cost produced per kilogram of rice at Rp. 283.8. Breakeven point values obtained for rice mills is 139.19hours / year or 35,342.784 kg of paddy / year. In addition, based on sensitivity analysis, obtained value net present value (NPV) is Rp. 168,628,529.933, the internal rate of return (IRR) is 40.11, and the gross value of B / C ratio is 1.50. Based on that results, we can conclude Kardi’s rice mill unit is feasible to run. After that, a sensitivity analysis was performed on several conditions that may occur. The selected conditions is rising diesel fuel prices, rising labor wage, and decrease the amount of annual milled. After calculating the sensitivity analysis, obtained some conditions which may cause the rice mill is not feasible to run.

Abstrak: Padi (Oryza sativa L.) adalah salah satu makanan pokok yang hampir sebagian besar masyarakat Indonesia mengkonsumsinya dan merupakan komoditi strategis yang tetap mendapat prioritas penanganan dalam pembangunan pertanian. Peningkatan produksi padi antara lain dapat ditempuh dengan cara perbaikan penanganan pascapanen. Penanganan pascapanen tanaman padi merupakan salah satu faktor penting dalam menentukan kuantitas dan kualitas beras yang dihasilkan. Salah satu aspek penting penanganan pascapanen padi adalah penggilingan padi. Proses penggilingan ini penting karena menentukan kualitas dan kuantitas beras yang dihasilkan. Dalam hal ini penggunaan mesin penggilingan padi diharapkan dapat meningkatkan rendemen dan mutu dari beras giling yang dihasilkan.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
