Judul: Production Performance and Daily Behavior of Local Male  Rabbits with Different Noise Levels
Abstrak: Kebisingan merupakan salah satu stresor yang dapat mempengaruhi performa ternak kelinci. Penelitian ini bertujuan untuk mengevaluasi tingkah laku harian dan performa kelinci jantan lokal dengan tingkat kebisingan berbeda. Penelitian ini menggunakan analisis uji T independent untuk membandingkan 2 perlakuan yaitu tingkat kebisingan A yaitu 40-50 db (tingkat kebisingan area lingkungan sekitar penelitian) dan tingkat kebisingan B yaitu 80-90 db (kebisingan yang diatur menggunakan music speaker). Peubah yang diamati adalah tingkah laku harian kelinci (makan, minum, eliminasi, grooming, istirahat, dan stereotypes), serta performa kelinci (konsumsi pakan harian, pertambahan bobot badan harian (PBBH), dan mortalitas kelinci). Hasil analisis menunjukan bahwa tingkah laku makan dan istirahat kelinci pada perlakuan A dan B tidak berbeda nyata. Selanjutnya tingkah laku grooming pada perlakuan tingkat kebisingan B nyata lebih tinggi dibandingkan pada tingkat kebisingan A dan tingkah laku minum, eliminasi, begerak, dan stereotypes pada perlakuan tingkat kebisingan A nyata lebih tinggi dibandingkan dengan perlakuan tingkat kebisingan B. Konsumsi pakan dan PBBH kelinci yang dipelihara pada tingkat kebisingan yang lebih tinggi mengalami penurunan. Selanjutnya kematian terjadi pada kelinci yang dipelihara dengan tingkat kebisingan yang lebih tinggi., Noise is one of the stressors that can affect the performance of rabbits. This study aims to evaluate the daily behavior and performance of local male rabbits with different noise levels. This study uses an independent T test analysis to compare 2 treatments, namely the noise level A, which is 40-50 db (noise level in the surrounding area of the study) and the noise level B, which is 80-90 db (noise regulated using music speakers). The observed variables were daily behavior of rabbits (eating, drinking, elimination, grooming, resting, and stereotypes), as well as rabbit performance (daily feed consumption, daily body weight gain (PBBH), and rabbit mortality). The results of the analysis showed that the eating and resting behavior of rabbits in treatments A and B were not significantly different. Furthermore, grooming behavior in noise level B treatment was significantly higher than noise level A and drinking, elimination, moving, and stereotyping behavior in noise level treatment A was significantly higher than noise level B treatment. Feed consumption and PBBH of rabbits reared at higher noise levels decreased. Further deaths occurred in rabbits kept with higher noise levels.

Judul: Tingkah Laku Harian dan Pola Makan Kelinci Lokal Pada Jenis Lantai Kandang yang Berbeda
Abstrak: The aim of this study was to analyze daily and ingestive behaviour of male local rabbit in different cage floor. Total rabbits used in this study were 15 heads (average body weight was 824±74,43 g) that were allocated into 3 treatments (bamboo, husk mats and wire cagefloor). The data of daily behaviours including ingestive (eating and drinking), locomotion, elimination, grooming, stereotype and resting behaviors were collected during 57 days. The data were analyzed with non parametric Kruskal- Wallis analysis. The results showed that effect of different cage floors was not significantly different on the rabbit daily behaviours. The observations also showed that rabbit that were kept in bamboo cage floor showed that drinking behaviours was significantly higher around noon than in the morning or late afternoon and the behaviours of locomotions in the morning was higher than around noon and late afternoon. In wire cage floor, resting behaviour during the day was significantly higher than in the morning or late afternoon. However, between the three cage types were similar the eating patterns behaviours observed, smelling, biting, chewing and swallowing. It can be concluded that the use of bamboo cage floor types, husks and wire can be used for raising local rabbits by considering the availability of the cage floor materials.

Judul: Penyusunan Overlap Graph menggunakan Suffix Tree pada DNA Sequence
Abstrak: The DNA sequence assembly is very important in genome analysis. This step aims to reconstruct contigous DNA fragment (contigs) from short fragment by concatenating fragments based on the overlap region among them. This method employs overlap graph for solving the problems. In this graph, nodes represent fragments and edges represent overlap. This research developed a software for constructing overlap graph using suffix tree. The evaluation was conducted by measuring the number of nodes, number of edges, and the execution time in many values of minimum overlap. The minimum overlap is defined as the minimum length of substring which is considered as the overlap region between two fragments. The evaluation results showed that the number of nodes, the number of edges, and the execution time were increased with the decreasing of the minimum overlap value.
