Judul: Microclimate of Cages and Body Surface Temperature of Mud Buffalo with Misting System
Abstrak: Pertambahan jumlah penduduk yang meningkat memengaruhi kebutuhan protein hewani di Indonesia. Potensi pengembangan ternak potong kerbau lumpur dapat menjadi solusi dalam pemenuhan kebutuhan daging. Kondisi lingkungan ternak yang nyaman dibutuhkan kerbau untuk meningkatkan produktivitas ternak dengan melihat mikroklimat kandang dan suhu permukaan tubuh ternak kerbau. Penelitian ini bertujuan untuk menganalisis pengelolaan mikroklimat kandang melalui sistem pengabutan dalam menurunkan suhu permukaan tubuh ternak kerbau. Penelitan menggunakan tiga ekor kerbau lumpur dara dengan umur sekitar dua tahun. Analisis data menggunakan metode deskriptif untuk pengamatan suhu udara kandang, kelembapan udara kandang, Temperature Humidity Index (THI), suhu komponen kandang, dan suhu permukaan tubuh ternak. Hasil penelitian menunjukan bahwa pemberian pengabutan air dapat menurunkan nilai Temperature Humidity Index (THI) kandang pada waktu pagi dan siang hari mendekati zona nyaman kerbau. Pemberian pengabutan air berpotensi memperbaiki mikroklimat kandang dan menurunkan suhu permukaan tubuh ternak kerbau., Increasing population growth affects the need for animal protein in Indonesia. The potential for the development of mud buffalo beef cattle can be a solution in meeting the demand for meat. Buffaloes need comfortable livestock environmental conditions to increase livestock productivity by looking at the microclimate of the cage and the body surface temperature of the buffalo. This study aims to analyze the management of the stable microclimate through the misting system in improving the body surface temperature of buffaloes. This study used three mud buffaloes aged about two years. Data analysis used a descriptive method to observe cage air temperature, cage air humidity, Temperature Humidity Index (THI), cage component temperature, and livestock body surface temperature. The results showed that the application of misting system can reduce the value of the Temperature Humidity Index (THI) of the cage in the morning and afternoon close to the buffalo's comfort zone. Giving misting system has the potential to improve the microclimate of the pen and reduce the body surface temperature of the buffalo.

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.
