Hubungan korelasi persepsi susu UHT dan susu pasteurisasi terhadap perilaku mengonsumsi (jenis susu yang dikonsumsi dan frekuensi minum) didapati hasil yang signifikan., Students as the nation's successor must fulfill adequate nutrition, one way is by consuming milk. This study aims to determine the perceptions and consumer behavior of IPB students on the consumption of UHT milk and pasteurized milk. The sample respondents in this study were 203 IPB students from various faculties who were selected using The Stratified Random Sampling technique. Nominal data were tested by the Chi square test and ordinal data were tested by the Rank Spearman test. The results showed that perception of the price and packaging of UHT milk and pasteurized milk was not significantly different. The frequency of drinking student milk is 2-3 times a week with dominant UHT milk consumed. The most purchased packaging and the volume for one consumption of drinking milk is 250 mL.

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.
