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 Usaha Peternakan Ayam Kampung di PT Sumber Unggas Kabupaten Bogor
Abstrak: Konsumsi per kapita ayam kampung meningkat setiap tahun, peningkatan itu mengindikasikan peluang usaha ayam kampung memiliki prospek yang baik. Hal itu dimanfaatkan oleh PT Sumber Unggas yaitu dengan menjalankan usaha peternakan ayam kampung. Tetapi, tingkat mortalitas ayam selalu melebihi standar yang ditetapkan perusahaan dan berfluktusai selama 18 siklus poduksi, hal itu disebabkan keberadaan risiko produksi. Penelitian ini bertujuan untuk mengetahui sumber risiko produksi ayam kampung yang sesuai dengan kondisi peternakan. Kemudian menganalisis probabilitas dan dampak risiko serta merumuskan alternatif strategi. Penelitian ini menggunakan metode z-score dan Value at Risk dalam menganalisa probabilitas dan dampak risiko. Hasil dari penelitian adalah teridentifikasinya empat sumber risiko yaitu penyakit, suhu, kualitas Day Old Chicken (DOC), dan afkir. Nilai probabilitas yang diperoleh adalah penyakit 39.74 persen, afkir 33 persen, suhu 32.28 persen, dan kualitas DOC 25.14 persen. Sedangkan nilai dampak risiko yang diperoleh adalah penyakit Rp130 933 510, afkir Rp47 579 427, suhu Rp31 266 623, dan kualitas DOC Rp33 476 182. Penelitian ini merumuskan dua strategi yaitu strategi preventif dan strategi mitigasi dalam menangani sumber risiko yang teridentifikasi.

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.
