Judul: Analisis Kelayakan Usaha Ternak Ayam Broiler pada Peternakan Lestari Rizqi Aditya Kabupaten Kampar, Provinsi Riau
Abstrak: The increasing price of beef leads to increasing demand of the broiler chicken meat. This situation can be seen as an opportunity to develop domestic production of broiler chicken. Lestari Rizqi Aditya (LRA) used this opportunity to establish a boiler poultry business in 2007. This research aims to analyze the feasibility of the LRA and to calculate the incremental net benefit due to the changes of technology. The research was conducted on boiler poultry business of LRA, Kampar District, Riau from February to June 2013. The method of analysis used in this study are a qualitative analysis to analyze the non-financial feasibility such as market, technical, legal, management, social, and environmental aspects, as well as quantitative analysis based on investment criteria, switching value, and incremental net benefit. The result of non financial feasibility analysis showed that LRA is feasible. Financial feasibility analysis showed that LRA is feasible with NPV Rp134 313 210, Net B/C 3.199, IRR 45%, PP 6 years, and the incremental net benefit Rp161 714 109.

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.
