Judul: Analisis Risiko Produksi Usaha Peternakan Ayam Kampung di Jimmy’s Farm Cipanas Kabupaten Cianjur Jawa Barat
Abstrak: Native chicken is a kind of local chicken in Indonesia. The opportunity of native chicken farm business is more attractive and rapidly growing. The number of population and average consumption per capita is increasing, beside that the price of native chicken production was also relatively stable, in fact it’s tend to increase and never been shaken by market price fluctuations. However, the cultivation of native chicken remains faced with risk of production. The risk of production become one of the obstacles in the process of native chicken farming in Jimmy's Farm which is causing losses to the company. This study intend to analyze the sources of production risk and it's impact, then analyze alternative strategies appropriate to manage the source of risk. There are three sources of risk at Jimmy's Farm with probability value and impact that generated by each sources. The source of the risk are: disease, air temperature inside the stable, and non-diseases. The propose of alternative strategy to manage the sources of risk of the air temperature is by using preventive strategy, and for the source of risk of disease is by using preventive and mitigation strategies to prevent and minimize the risk along with the impact produced.

Judul: Analisis Risiko Produksi Penetasan Ayam Kampung pada CV Jimmy’s Farm Cipanas, Kabupaten Cianjur, Jawa Barat
Abstrak: Bibit unggul ayam kampung sulit untuk diperoleh, hal ini terjadi karena masih sedikit peternakan yang melakukan pembibitan ayam kampung. CV Jimmy’s Farm merupakan salah satu peternakan ayam kampung yang bergerak dibidang pembibitan dan budidaya ayam kampung. Fluktuasi persentase daya tetas pada CV Jimmy’s Farm mengindikasikan adanya risiko produksi. Tujuan dari penelitian ini yaitu mengidentifikasi sumber risiko produksi, menganalisis probabilitas dan dampak yang diakibatkan oleh sumber risiko produksi, serta merumuskan alternatif risiko. Metode analisis yang digunakan adalah metode zscore dan Value at Risk (VaR). Berdasarkan hasil analisis z-score dan Value at Risk (VaR), sumber risiko produksi penetasan yang terdapat pada CV Jimmy’s Farm antara lain telur bening, pendarahan pada telur, telur mati saat inkubasi, dan terlambat menetas. Adapun strategi penanganan risiko yang direkomendasikan berdasarkan hasil pemetaan yaitu strategi preventif dan mitigasi. Perusahaan dapat melakukan strategi preventif dengan melakukan seleksi indukan dan seleksi telur dan melakukan strategi mitigasi dengan menjual telur bening.

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.
