Judul: Aspek Sanitasi Dan Higienitas Pangan Jajanan Anak Sekolah (PJAS) Di Kantin Sekolah Dasar Kota Depok
Abstrak: Dalam rangka mengikuti Aksi Nasional Pangan Jajanan Anak Sekolah (PJAS), Dinas Kesehatan Kota Depok menyelenggarakan program Penilaian Kantin Sehat di sekolah dasar Sekolah Dasar (SD) yang dilakukan setiap tahun dan bekerja sama dengan Institut Pertanian Bogor (IPB), Badan Pengawasan Obat dan Makanan (BPOM) dan Dinas Pendidikan Kota Depok. Penilaian kantin diikuti oleh sebelas SD yang masing-masing sekolah mewakili kecamatannya. Hasil penilaian kantin sehat diperoleh menggunakan metode descriptive survey. Aspek yang dinilai mencakup aspek lokasi, bangunan, dan fasilitas; aspek penjamah makanan; aspek makanan; dan aspek peralatan makan dan masak. Selain itu, juga dilakukan pengujian sampel makanan yang dicurigai mengandung bahaya kimia dan bahaya mikrobiologis. Pengambilan sampel dilakukan menggunakan metode purposive sampling method. Parameter yang diuji antara lain adalah Escherichia coli, formalin, boraks, rhodamin B, dan asam siklamat. Hasil penilaian kantin sehat menunjukkan bahwa rata-rata dari sebelas kantin SD di Kota Depok masih memiliki kondisi hygiene sanitasi yang belum sesuai dengan perundangan berlaku, terutama pada aspek makanan. Selain itu, hasil uji laboratorium menunjukkan bahwa formalin merupakan temuan yang terdeteksi paling banyak pada sampel makanan yang diambil dari sebelas SD.

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.
