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.

Judul: Pengaruh program keamanan pangan di sekolah terhadap pengetahuan penjaja pangan jajanan dan siswa Sekolah Dasar
Abstrak: Edukasi keamanan pangan bagi penjaja pangan jajanan anak sekolah (PJAS) merupakan hal yang harus dilakukan guna meningkatkan pengetahuan keamanan pangan. Hal ini juga penting bagi siswa sekolah dasar (SD), karena pengetahuan keamanan pangan akan berpengaruh pada pemilihan produk pangan yang akan dikonsumsi. Penelitian ini bertujuan untuk mengetahui kategori pengetahuan penjaja PJAS mengenai keamanan pangan dan pengaruh program keamanan pangan di sekolah terhadap pengetahuan penjaja PJAS, serta pengaruh penyuluhan keamanan pangan terhadap pengetahuan keamanan pangan siswa SD. Data hasil survei dari 20 provinsi di Indonesia diolah menggunakan program SPSS dengan metode analisis Pearson dan paired sample t-test. Hasil analisis menunjukkan bahwa 71.96% penjaja PJAS masih memiliki pengetahuan keamanan pangan yang kurang, dan hanya sebesar 28.04% penjaja PJAS yang memiliki pengetahuan keamanan pangan baik. Analisis antar variabel menunjukkan bahwa tidak ada pengaruh yang signifikan antara program keamanan pangan, yaitu (1) adanya peraturan keamanan pangan di sekolah dan (2) pemberian penyuluhan oleh sekolah terhadap pengetahuan keamanan pangan penjaja PJAS. Bagi siswa SD penyuluhan keamanan pangan memberikan peningkatan pengetahuan sebesar 19.41%., The importance of food safety education in order to enrich food safety knowledge of food vendor in elementary school (ES) should not be neglected. Not to mention, for elementary school students that could interfere their preference of food product. The aim of this study were to determine the level of food safety knowledge of food vendor, the impact of food safety program to food understanding, and the influence of food safety education toward ES students' knowledge. The data gained from 20 provinces in Indonesia were analyzed using SPSS through pearson analysis method and paired sample t-test. The result revealed that 71.96% of food vendors possessed a poor knowledge, and only 28.04% had a good knowledge about food safety. The result of analysis between variable showed that there was no significant effect of food safety programs, which were (1) the implementation of food safety regulations in school and (2) the application of food safety extension from school to food vendors. Food safety extension to ES students increased student knowledge of food safety up to 19.41%.

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.
