Abstrak: Traditional farmers have good experience in sheep farming but they still have weakness in management, especially in financial aspects in measuring business profit and loss. This research was purposed to explaining general condition and examinating financial aspect of sheep traditional farm in two villages Cibanteng and Cikarawang. Thirty farmer respondents from each village were interviewed, and clasified into two categories (scale I and scale II) based on average number of sheep. Data were analyzed by description method. The result showed that average of farmer’s cash revenue in Cibanteng Village were Rp 4 894 737 per year (scale I) and Rp 9 000 000 per year (scale II); average of farmer’s cash revenue in Cikarawang Village were Rp 3 642 857 per year (scale I) and Rp 8 000 000 per year (scale II). Although they had got profit by cash revenue, actually they was in loss condition and not productive yet, shown by number of sale <BEP (Break Event Point) and Revenue and Cost ratio (R/C) <1. However they continued to raise sheep by traditional method because there are many production factors that have never calculated (non-cash of cost production) so that was still a profitable farm activity. By assumption of potential production coefficient, 77 sheep must be sold per year to made equivalent profit with Bogor regional minimum wage by maintaining 38 ewes at the beginning of year and supported by implementation of good farming practices (GFP).

Abstrak: The objectives of this research are: (1) to describe the characteristic of farmer and their sheep farm; and (2) to analyze the financial feasibility of sheep farm and it's sensitivity. Cluster random sampling applied to choose 164 sample from 700 sheep farmers household population in Cibunian Village. The sheep farm were clasified into three categories based on ownership of sheep, namely scale I (0,75- 2,50 SDD or Adult Sheep Unit); scale II (2.51-4.75 SDD); and scale III (4,76-8,50 SDD). The result of this research showed chat generall (52,44%) farmer in Cibunian village comitted their sheep farm on scale I. Farmer of each scale in avarage were categorized into productive aged, have lots of experience on shap farm activities, but they have low education. The result of financial feasibility analysis showed that for 10 years at the interest rate of 9,50%, Net Resent Value (NPV)of sheep farm on scales I, II and III respectively is Rp (3.537.029,00); Rp (1.413.826,00); and Rp 1.770.5 19,00, with the values of Benefit Cost Ratio (BCR) are 0.67; 0,89; and 1 ,I 0. Internal Rate of R e m (IRR) on scale I1 and 111 respectively is 057 and 16,56%. Sensitivity analysis was counted on scale Ill. Sheep farm on scale 1II was not feasible if farm costs increased more than 9,97% or farm revenues decreased more than 9.06% ceteris paribus.

Abstrak: Composite membrane implants from biodegradable and biocompatible polymers such as chitosan, added with Fe3O4 magnetic nanoparticleshydroxyapatite (MHAP) is an alternative that is appropriate for bone tissue engineering. The MHAP was first synthesized using coprecipitation method with 3 different composition, with the ratio of Fe3O4 : hydroxyapatite is 3:7, 4:6, and 5:5 by mass. The composite membrane chitosan-MHAP (MK K-MHAP) was then synthesized by mixing a chitosan solution and the best MHAP composition (10, 20, 30, and 40% w/w of the mass of chitosan). Characterization using X-ray diffraction confirmed the formation of Fe3O4 and hydroxyapatite phase on the MHAP. The magnetic saturation value and size of Fe3O4 magnetic nanoparticles increase with the increasing Fe3O4 composition in MHAP and MK K-MHAP which characterized based on its magnetic hysteresis and particle size distribution curve, respectively. The morphology of the best composition of MHAP composite was analysed using transmission electron microscope. Molecular interactions in MK K-MHAP was characterized based on infrared spectra. Immersion test of MK K-MHAP showed optimum state at 30% mass MHAP composition in chitosan matrix with calcium concentration released about 1000 ppm within 144 hours.
