Judul: Performa Ayam Ras Petelur pada Kandang Cage dan Litter.
Abstrak: One of the main tools that have to be considered for an intensive and efficient laying hens maintenance was cage aspect. The purpose of this research was to see the effect of cage treatment and the unit cost analysis of laying hens. The observed parameters were feed consumption, egg weight, feed ratio convertion, hen day production, egg exterior quality, and unit cost. The research was done by complete randomized design with two cage treatment and 6 replication that containing 16 (cage) and 25 (litter) laying hens each. The data was analized with Statistical Package for the Sosial Science (SPSS) programs by independent sample T-test. The result showed that the cage treatment has significantly differencies foward feed consumption, feed ratio convertion and eeg cleanliness with dirty level below 25%. The significantly differencies in egg weight and hen day have been showed in the first 2 and 3 observation weeks. The best unit cost was the laying hens mainternance in cage system.

Abstrak: Housing management is one factor that influence the incident of foot pad lesion and breast blister. Foot Pad Lesion (FPL) and Breast Blister (BB) are inflamation of the subcutant tissue on the region foot pad and breast of the chicken caused by intensive rubbing between skin and house floor. This study was designed to evaluate litter and cage system on the incident of FPL, BB, and performance of laying hens. This research used closed housed with temperature range of 18 until 22 oC. A total of 18 hens are reared on bamboo cage and 18 hens on rice husk litter. A number of 9 samples were taken from each housing system to evaluate the score of FPL and BB, egg production, feed intake, and feed conversion ratio. The t-Test was applied to compare the all trait between litter and cage. The result of the experiment showed that the incident level of FPL and BB on hens reared in litter and cage did not significantly different (P>0.05). Increasing incident of FPL in cage was higher than litter (100% vs 33.33%) at fourth week, but overall FPL at both of housing systems increase from first week until fourth week. In addition, egg production, feed consumption, body weight gain and feed conversion ratio were not different.

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.
