Judul: Studi Perilaku Ayam Broiler Berbasis Liputan Visual dalam Kandang Tertutup
Abstrak: One of the problems being faced by Indonesian society is inadequacy of meat supply for consumption per capita. One of the most popular and affordable meat in Indonesia, at large, is chicken meat. However, the chicken meat production and supply up to now is still inadequate to meet the meat requirements of Indonesian people. The main factor that causes inadequate of chicken meat production is on-farm managerial factor. This research aims to study the behavioral characteristics of broiler in the broiler house based on visual orservation. The result of this research is expected to be able to increase the quality of broiler production management. The observations were concentrated on the behavior of broilers due to three parameters: temperature, lighting, and noise. The observed behavior include the behavior of locomotion and rest, grouping, shelter seeking, eat and drink, and panting. Temperature is the most significant parameters affecting the behavior of locomotion and rest, grouping, shelter seeking, eat and drink, and panting in broilers in this research. Based on this research, 60% of broilers are affected by high temperature exposure. Panting was the most observable behavior in high temperature exposure. The next observable behavior was shelter seeking due to high temperature exposure. Light intensity directly affects the behavior of locomotion and rest, and the behavior of eat and drink. The most observable behavior affected by increasing of light intensity was locomotion. The higher the light intensity the higher the quantity of locomotion of broilers. This implies that broilers become more active and has less of rest. Noise lower than 80 dB did not affect significantly the behavior of broilers.

Judul: Respon Tingkah Laku Ayam Broiler Pada Suhu Kandang yang Berbeda
Abstrak: High ambient temperature satch in tropics causes heat stress to chickens that reduced feed consumption and productivity. Under this situation, the chickens often changed their oreintation showed by behavioural changes. This experiment aimed to study the behavioural response of broiler chickens at different ambient temperature of neutral (22 oC), heat (30 oC ) and surronding or environment temperature (accordance with surronding temperature). The behavioural observation was carried out with scan sampling method. There were five behavioural traits observed : eating, dringking, panting, resting, and locomoting. The result showed significant different in panting in day 15, 21 and 27 ( P<0.05 ) among ambient temperature. However, the other behaviours did not different

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.
