Judul: Status Kecernaan Pakan dan Produksi Susu Induk Sebagai Indikator Pertumbuhan Pedet pada Sapi Perah (Friesian Holstein) di KPBS Pangalengan
Abstrak: Status of feed digestibility, milk production, and growth in cow and calf are indicator of performance improvement milk production and cow population in the dairy farm area. Study about the relation between feed, digestibilility, and performance (milk production and growth of calf) in the dairy farm area have not much done. Pangalengan is a central of dairy farm that coordinate by KPBS. The purpose of this research is to know about status of feed digestibility, milk production, and growth of calf in public farm KPBS Pangalengan. Sixteen weaning cows were used for feed digestibility and milk production observation, also sixteen calfs were used for body weight observation. The observational data of the overall parameters was analyzed descriptively then statistically using analysis of variance (Anova) method. Status of feed digestibility and milk production of dairy cows in KPBS Pangalengan can be used as indicators of the growth calves. Percentage of feed digestibility which were dry matter 81.40%, crude protein 89.29%, crude fat 95.12%, crude fiber 63.54% and ash 77.34% show the feed digestibility was good. Milk production showed good quality in the first 8 weeks lactation which was 18.74 liter/cow/day. Growth of body weight in calf was 0.2 kg/calf/day. Based of these result, Dairy farm KPBS Pangalengan have good management for dairy cows that would keep the cows healthy and productive.

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.
