Judul: Penilaian Lomba Kantin Sehat Sekolah Dasar Di Kota Depok Tahun 2015
Abstrak: Dalam rangka penyehatan konsumsi pangan jajanan anak sekolah yang sehat, Dinas Kesehatan Kota Depok melakukan intervensi penyehatan makanan melalui kegiatan penyuluhan, seminar dan Lomba Kantin Sehat. Penilaian lomba kantin sehat yang bekerjasama dengan Institut Pertanian Bogor (IPB), Dinas Pendidikkan, dan Badan Pengawas Obat dan Makanan (BPOM) berdasarkan hasil analisis kimia dan mikrobiologi terhadap pangan jajanan yang dijajakan di kantin sekolah serta data observasi dan wawancara tim penilai kantin sehat. Pengambilan sampel dilakukan di sebelas sekolah dasar (SD) yang masing-masing sekolah mewakili kecamatannya. Analisis kimia meliputi bahan tambahan pangan yaitu asam siklamat, dan bahan berbahaya yaitu formalin, boraks, rhodamine B dan methanil yellow. Analisis mikrobiologi yaitu bakteri E.coli dan Salmonella. Pengumpulan data diperoleh dari hasil observasi tim penilai lomba kantin sehat berdasarkan aspek sarana dan prasarana kantin sekolah, aspek kelengkapan, aspek gizi dan kesehatan, dan aspek keamanan pangan serta wawancara tim penilai lomba kantin sehat terkait kelengkapan dokumen sekolah. Hasil analisis kimia dan mikrobiologi menunjukkan tidak adanya kontaminasi bahan berbahaya pada sebelas sekolah. SD A10 memperoleh nilai tertinggi berdasarkan hasil penilaian tim penilai lomba kantin sehat, sedangkan SD A5 memperoleh nilai terendah.

Judul: Penilaian Kantin Sehat Pangan Jajanan Anak Sekolah di Kota Depok
Abstrak: In order to promote the consumption of healthy food, Depok health service held a healthy canteen program assessments undertaken annually and coorporated with Bogor Agricultural University and National Agency of Drugs and Foods Controls. The healthy canteen assessment was consist of chemistry and microbiological analyses on food snacks sold in school canteens and also the aspects of physical building conditions. Canteen assessment was followed by 11 elementary schools, each school represented subdistrict. Heavy metals contamination analysis which was plumbum, food addictive which was cyclamate acid, and hazardous material such as formaline, borax, rhodamine B and methanil yellow. Microbiological analysis of E.coli and Salmonella. Healthy canteen assessment using the reduction value system was done if the parameters analyzed were detected. SD A4, A7, A8, SD and SD A11 earned the highest score,while SD A2 and A10 earned the lowest score.

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.
