This research use a cross-sectional study design. This research was located in two elementary schools at the city and district which have caffetaria and similar other facilities. Selection of the research location was determined by purposive sampling methode, with criterias 1) The school has a caffetaria, 2) Has a strong commitment, 3) Recomended government. Based on the criterias, two elementary school from city and district of Bogor was taken as the subjects based on the acreditation status. All population of the snack hawkers are also taken as the subjects (total 47 hawkers). The process of data analyzing was done by descriptive and inferencial methode. The correlation between variables were analyzed with Pearson’s correlation test, whereas the difference between variables were analyzed by Independent Sample T-Test. The result of this research is that the application Most of the subjects (53% of subjects) are lack of information about nutrition and food safety. Statistical test shown that there are no significant differentiation for nutritional education rate and food safety knowledge based on location, accreditation status and seller groups classification. However, correlation test shown that there is a positive relation between education rate and nutrition and food safety knowledge of the subjects (r=0.356*, p=0.014). As a whole result of subject’s food safety practice, about 51.1% of them are in the category of inadequate. Statistical differential test shown that there are no significant differentiation on food safety for student’s snack in the categories based on location, accreditation status and seller groups. Correlation test result shown that nutritional and food safety knowledge has a negative relation with food safety practice for student’s snack (r=-0.079, p>0.05). Based on the application of the student’s snack rules, every school have rules for student’s snack which most of them are unwritten. Most of the rules are about food sanitation, discipline of the street hawker’s and the use of food additive. Those rules are not applied in an optimal fashion because most of the subjects are in the category lack of knowledge about food safety and they are still using food additives. The applications of those rules by most of the schools are in the medium category and only one of them applied the rules perfectly. The school has a committee who involved in the making of those rules. The street snack hawkers’ perception about application of those rules have varieties, even 51.1% of them do not know that there are some rules from the schools. This might be because lack of socialization about the rules. Correlation test result shown that there is no significant relation between the application of the rules with nutrition and food safety knowledge (p>0.05), and also no significant relation between the application of the rules with food safety practice (p>0.05).

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.
