Judul: Analisis Kelayakan Usaha Penggemukan Domba pada CV Mitra Tani Farm di Desa Tegal Waru Kecamatan Ciampea Kabupaten Bogor
Abstrak: CV Mitra Tani Farm is a sheep and goats fattening bussiness located in Tegal Waru Village Ciampea Subdistrict Bogor Regency. In working out the sheep fattening, MT Farm can afford ownership or partnership with farmers who currently partnering with the business units MT Farm "Rumah Kambing". The purpose of this study are: 1) to analyze the feasibility of fattening sheep CV Mitra Tani Farm viewed from the non-financial aspects such as market aspects, technical aspects, management aspects, legal aspects, social and environmental aspects, 2) to analyze the feasibility of fattening sheep CV Mitra Tani Farm if cultivated by ownership or patnership views on the financial aspects of the NPV, IRR, Net B/C, and Payback Period, and 3) to analyze the switching value of this sheep fattening CV Mitra Tani Farm if there is a decrease in variable cost of production and increase the feasibility of the venture. The results of this study show 1,040 sheeps fattening business in CV Mitra Tani Farm is feasible based on non-financial aspects and financial aspects show this bussiness which is feasible by ownership or partnership because it has appropriated the investment criteria. Switching value calculation results show the maximum limit of increasing lamb price with ownership is 6,33% and the maximum decrease in carcass percentage is 5,82%. Therefore, the maximum of increasing lamb price with partnership is 2,91% and the maximum decrease in carcass percentage is 2,67%.

Judul: Analisis kelayakan usaha ternak domba rakyat di Desa Cibunian Kecamatan Pamijahan Kabupaten Bogor
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.

Judul: Variasi Waktu Reaksi Sintesis terhadap Karakteristik Struktural Nanoplatelet α-Zirkonium Fosfat
Abstrak: Nanoplatelet α-ZrP merupakan material anorganik yang bersifat asam dan berstruktur kristal dengan rumus Zr(HPO4)2.H2O. α-ZrP disintesis dengan ragam waktu reaksi hidrotermal selama 3, 6, 12, 18, dan 24 jam untuk megevaluasi pengaruh waktu reaksi sintesis pada morfologi, ukuran partikel, dan kapasitas tukar kation (KTK). Spektrum inframerah nanoplatelet α-ZrP dari kelima ragam waktu tersebut menunjukkan keberadaan ikatan O-H, P-OH, P-O, dan PO4. Difraksi sinar-X memperlihatkan terdapat empat puncak 2θ yang serupa dengan pola difraksi standar α-ZrP dari data JCPDS. Payaran mikroskop elektron menampilkan bahwa material α-ZrP berukuran nanometer pada bagian ketebalan partikelnya dan berbentuk platelet yang pipih. Nanoplatelet α-ZrP memiliki rentang distribusi ukuran partikel yang luas. Perbedaan ukuran disebabkan oleh ragam waktu dalam proses hidrotermal. Ukuran partikel semakin besar seiring lamanya proses hidrotermal. Penentuan KTK menunjukkan semakin lama waktu sintesis maka semakin kecil nilai KTK.
