Judul: Pengembangan e-Notifikasi Pangan Jajanan Anak Sekolah (PJAS) Untuk Siswa Sekolah Sebagai Perwujudan Pengawasan Keamanan Pangan Mandiri
Abstrak: Street foods is one of the types of foods that are known in the public, especially students. Street Foods for Students (SFFS) sampling results by National Agency for Drug and Food Control RI period 2008-2010 shows that 40-44% street foods does not meet the requirement. The study is covertly designed to make e-notfication food safety Street Foods for Students (e-notification food safety SFFS) and e-notification national action of Street Foods for Students (SFFS NA) to the students consisting of procedure e-notification, a questionnaire, and instructions chargng a questionnaire to facilitate of self monitoring food safety by the students. Besides, to see if the e-notification can be applied for elementary students class 4 to 6. Making e-notification SFFS consisted of 6 stages: (1). making concept procedures e-notification, a questionnaire, instructions charging a questionnaire; (2). socialization concept e-notification on training of trainers technical guidance; (3). socialization concept e-notifications to students; (4). validity and reliability of the questionnaire; (5). Interview; (6). Repair the concept of e-notification. The percentage of the students who have been fill a question in accordance with a clue charging is good enough, it is above 60 % if averaged of any questions.SPSS output used the pearson correlaton technique to test the validity (at 5% significance level) shows that most of the questions that has tested the validity has r count larger than r table product moment (0.279). SPSS Output used split half and Cronbach Alpha techniques to test the reliability (at 5% significance level) with value correlation between part 1 and part 2, the value of Guttman Split half, and the value of Cronbach Alpha are larger than r table product moment for (0.279). Thus, the most questions at questionnaires that tested their validity and reliability are valid and reliable. Repair a questionnaire done by improving and disposing of the question that is not valid, change the position of the question as well as by derivation with the addition of an arrowhead mark and the box. Repairs will be done on a clue charging a questionnaire as well as changes in the procedures to e-notification SFFS.

Abstrak: The main purpose of this research is to analyze the application of food safety rules and practice on student’s meal in elementary school at city and district of Bogor. 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: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
