Judul: Analisis Kelayakan Usaha Peternakan Ayam Broiler di Desa Kembiritan Kecamatan Genteng Kabupaten Banyuwangi
Abstrak: Broiler farm in Banyuwangi has a good prospect for investment. The aims of this study is to analyze feasibility of broiler farm and to analyze switching value for decreasing of output price, increasing of DOC price, feed price and variable cost. Data was collected from both primary and secondary data. Primery data was collected by interviewing the owner and staffs of the farm. The result of this study show that broiler farm is feasible in all of non financial dan financial aspects. With the interest rate 13.53 percent, this study revealed that NPV is Rp691 731 852, Net B/C is 2.70, IRR is 63 percent, payback period is 4 years and 1 month. Acording to switching value, this broiler farm is sensitive on decreasing of output price, increasing of variable cost and feed price.

Judul: Analisis Kelayakan Pengembangan Usaha Peternakan Ayam Broiler Di Desa Cihideung Udik, Kabupaten Bogor
Abstrak: Broiler chicken husbandry is the most favorited kind of husbandry because it has high level of demand of its product. Bogor is one of regions in West Java that has high demand of chicken husbandry product. The study aims to ( 1 ) analyze feasibility enterprise development of chicken farmer broiler look from non financial aspects as aspects market, the technical aspects, aspect management and legal, aspect social and cultural and environmental aspects ( 2 ) analyze feasibility enterprise development of chicken farmer broiler look from financial aspects ( 3 ) analyzed levels of sensibility (switching value) feasibility enterprise development of chicken farmer broiler. Based on the analysis aspect financial and non financial, business of chicken broiler has worthy to be developed. Because it seen from Net Present Value (NPV) was IDR6 058 082 368, net B/C 2.84%, IRR 39.26%, and Payback Period 3.2 years. The Discount Rate was 6%. Switching Value analysis showed that the increasing price of feed price by 10.11% and decreasing price of selling chicken by 6.31% were still feasible. Chicken broiler farm more sensitive to decrease price of selling chicken than increasing price of feed.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
