Judul: Physiological Responses with Water Misting using Water Sprinkler on Beef Cattle
Abstrak: Sapi pedaging merupakan jenis sapi yang dimanfaatkan dagingnya untuk pemenuhan protein hewani di Indonesia. Permasalahan yang dihadapi Indonesia adalah rendahnya produktivitas sapi. Peningkatan produktivitas sapi pedaging dapat dilakukan dengan cara membuat sapi berada pada zona nyaman dengan melihat respon fisiologis dari sapi tersebut. Penelitian ini bertujuan untuk mengetahui pengaruh pengabutan air terhadap respon fisiologis sapi pedaging dan mikroklimat kandang. Rancangan yang digunakan adalah uji-T berpasangan untuk variabel respon fisiologis dan mikroklimat kandang dengan melakukan sebanyak 5 kali ulangan dan Rancangan Acak Lengkap untuk mengetahui perbedaan antara suhu permukaan tubuh. Perlakuan terdiri dari sebelum pengabutan air dan sesudah pengabutan air. Hasil penelitian menunjukan bahwa perlakuan pengabutan air pada siang hari berbeda nyata (P<0,05) terhadap peubah suhu kandang, kelembaban kandang, temperature humidity index, suhu rektal, frekuensi pernapasan, dan frekuensi denyut jantung. Pengabutan air pada siang hari menurunkan variabel mikroklimat kandang dan sapi yang diukur hingga mendekati zona nyaman dan nilai faal sapi., Beef cattle is the type of cow that is commonly utilized for its meat to fulfill animal protein in indonesia. The problem facing Indonesia is the low productivity of cattle. The increase of productivity of cattle producer can actually be done by relocating the cattle towards the comfort zone by seeing the physiological response. The purpose of this research is to find out the misting of water towards its effect on the physiological response and the microclimate of the cattleshed. The design used was a paired T-test for physiological and microclimate response variables with 5 replications and a completely randomized design to determine the difference between body surface temperatures. The treatment consisted of before water misting and after water misting. The results showed that treatment of misting water in the afternoon was significantly different (P<0.05) on the variables of cage temperature, humidity, temperature humidity index, rectal temperature, respiratory frequency, and heart rate. Water misting in the afternoon in cattle produced a good effect on all physiological response variables.

Judul: Pengembangan Kandang Inovatif Sapi Pedaging untuk Pengelolaan Mikroklimat Melalui Sistem Pengabutan
Abstrak: Sapi pedaging merupakan ternak penghasil daging dari jenis ruminansia besar. Kondisi lingkungan ternak diupayakan tetap berada di thermoneutralzone. Diperlukan sebuah modifikasi lingkungan terkait pengelolaan mikroklimat melalui sistem pengabutan dengan menggunakan alat sprinkler water. Tujuan penelitian ini menganalisis pengelolaan mikroklimat kandang melalui sistem pengabutan dalam memperbaiki respon fisiologis sapi pedaging. Peubah yang diamati yaitu suhu komponen kandang, suhu udara, kelembapan udara, Temperature Humidity Index (THI), frekuensi pernapasan, frekuensi denyut jantung, dan suhu rektal. Metode analisis yang digunakan yaitu uji-T tidak berpasangan 5 kali ulangan. Hasil penelitian menunjukkan bahwa perlakuan sebelum dan setelah pengabutan air pengukuran pagi berbeda nyata (P<0,05) tinggi pada semua peubah yang diamati. Pengabutan air memberikan efek penurunan suhu komponen kandang, suhu udara, kelembapan udara, Temperature Humidity Index (THI), frekuensi pernapasan, frekuensi denyut jantung, dan suhu rektal., Beef cattle are meat-producing livestock of large ruminant species. The environmental conditions of livestock are kept in the thermoneutral zone. An environmental modification related to microclimate management is required through a misting system using a water sprinkler. The purpose of this study was to analyze the microclimate management of the barn through the misting system in improving the physiological response of beef cattle. The variables observed were the temperature of the components of the barn, the air temperature, the air humidity, the Temperature Humidity Index (THI), respiratory frequency, heart rate, and rectal temperature. The analytical method used in this is unpaired T-test five replications. The results showed that the treatment before and after the morning measurement water misting was significantly different (P<0.05) in all the observed variables. Water misting has the effect of decreasing the temperature of the barn components, air temperature, humidity, Temperature Humidity Index (THI), respiratory rate, heart rate, and rectal temperature.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
