Judul: Penentuan Titik Kritis pada Pangan Jajanan Anak Sekolah Berbasis Perikanan di Kota Bogor
Abstrak: Pangan jajanan berbasis perikanan seperti siomay, otak-otak, pempek banyak dijual di sekitar sekolah. Penelitian ini bertujuan untuk mengidentifikasi titik kritis pada rantai penyediaan pangan jajanan berbasis perikanan agar potensi cemaran fisik, mikrobiologi maupun kimia dapat ditangani secara tepat. Penentuan titik kritis dilakukan dengan cara mengidentifikasi potensi bahaya yang muncul pada setiap tahapan proses kemudian berdasarkan bahaya yang teridentifikasi signifikan ditentukan titik kritisnya. Titik kritis terdapat pada tahap pembelian bahan baku karena potensi histamin, utamanya dari ikan golongan scromboid seperti tenggiri, tuna dan tongkol. Pemasakan merupakan tahapan kritis untuk mengatasi bahaya mikrobiologi seperti Salmonella sp., Vibrio sp., S. aureus, E. coli, L. monocytogenes, parasit dan virus. Selain itu bahaya kimia berupa aflatoksin yang potensial terdapat pada sambal kacang dan Rhodamin B yang potensial terdapat pada saus cabai merupakan penyebab tahap penambahan bahan pelengkap pada saat penyajian menjadi titik kritis. Adanya migrasi monomer dari : kemasan plastik, melamin dan styrofoam perlu diwaspadai.

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: Implementasi Algoritme Enkripsi Advanced Encryption Standard secara Paralel dengan GPU NVIDIA CUDA
Abstrak: Processor streaming architecture in GPU has provide general purpose computation which have its own potential to help CPU with its parallel computation capability. One example of supported processor streaming architecture is Fermi which is developed by NVIDIA. Furthermore, NVIDIA has developed its own software development kit namely CUDA, which can integrate many popular existing programming languanges such as C++ for GPU-based parallel computation. This research focus on the implementation of parallel AES algorithm with GPU and analyze the performance result of the implementation in two different NVIDIA devices, namely NVIDIA GeForce GT220 and NVIDIA Quadro 600. In general, the performance of parallel GPU computation is better than sequential computation for large data input. It is obtained that the maximum speedup of NVIDIA GeForce GT220 in 8 MB input is 89.3 with 180% efficiency. Higher speedup of 101.6 can be obtained by NVIDIA Quadro 600 with the same input size with around 100% efficiency.
