Judul: Penyimpanan dingin kulit lumpia dan siomay di dalam kemasan plastik dalam skala rumah tangga
Abstrak: Spring roll wrapper is tlte slice for wrapping the spring roll pastry. It is made from wheat flour, eggs, vegetable oil, and salt. Spring roll wrapper is not a ready-made food because it needs to be processed with other materials, such as vegetables and meat so that it becomes a processed food material which is called spring roll pastry which can be consumed. Siomay is a processed food material. It is made from siomay wrapper, meat, garlic, onions, vegetable oil, salt, and sugar. The common problem on the processed food materials like spring roll wrapper and siomay is their short shelf life because of their relatively high water content. Good packaging which concerns with the characteristics of tlte product is one solution amongst the others to extend the shelf life and protect the product from spoilage and contamination.

Judul: Optimizing the Quality of Sweet Premix Corn Dog Flour Through Storage and Packaging Design Considering Water Activity
Abstrak: PT LeGitt Boga Mandiri sebagai perusahaan makanan berbasis tepung terigu telah menciptakan varian produk terbaru dari tepung premix yaitu tepung sweet premix corn dog. Menjaga kestabilan mutu pada produk perlu dilakukan dengan berfokus pada kondisi lingkungan penyimpanan produk dan kemasan yang digunakan. Pengujian isotermi sorpsi air dilakukan untuk mengetahui kenaikan kadar air pada bahan yang digambarkan menggunakan kurva isotermi sorpsi air (ISA). Dari kurva ISA tersebut dilakukan pembagian fraksi daerah air terikat dengan masing-masing batas atas pada daerah primer, sekunder dan tersier dengan nilai aktivitas air 0,09, 0,69 dan 1. Berdasarkan SNI 01-4476-1998, batas kadar air pada tepung sweet premix corn dog sebesar 12% dilampaui pada lingkungan penyimpanan dengan kelembaban relatif (RH) > 0,69% pada suhu 28oC. Uji cemaran mikroba juga dilakukan dengan diketahui adanya nilai angka lempeng total (ALT), kapang dan khamir dengan taraf aman. Untuk melindungi produk dari kenaikan kadar air yang dipengaruhi oleh lingkungan penyimpanan, maka digunakan jenis material kemasan Polyethylene (PE) dan papersack sebagai material kemasan terbaik yang tersedia di pasaran. Berdasarkan penentuan material kemasan maka dirancang 3 desain mock up kemasan. Hasil penilaian oleh 32 panelis menunjukkan bahwa desain mock up kemasan kedua (#2) memiliki nilai kepuasan tertinggi., PT LeGitt Boga Mandiri, a flour-based food company, created a new product variant called sweet premix corn dog flour. The company ensured product quality stability by focusing on product storage conditions and the packaging used. Water sorption isotherm testing was conducted to determine the increase in water content in the material, described using the water sorption isotherm (WSI) curve. From the WSI curve, the fractions of bound water in the primary, secondary, and tertiary regions were determined with respective upper limits at 0.09, 0.69, and 1 water activity values. According to the SNI 01-4476-1998 standard, the water content limit for sweet premix corn dog flour is 12%, which was exceeded when stored in an environment with relative humidity (RH) > 0.69% at 28°C. Microbial contamination tests were also conducted by determining the total plate count (TPC), mold, and yeast with a safe threshold. To protect the product from water content increases influenced by storage conditions, Polyethylene (PE) and papersack packaging materials were used as the best available options in the market. Based on the determination of packaging materials, three mock-up packaging designs were created. The evaluation results by 32 panelists showed that the second mock-up packaging design (#2) had the highest satisfaction score.

Judul: Evaluasi Koefisien Dan Laju Inbreeding Pada Kuda Militer Di Detasemen Kavaleri Berkuda (Denkavkud) Parongpong, Bandung
Abstrak: This research was conducted to evaluate the inbreeding coefficient and its rate of military cavalry horse were reared by Denkavkud. There are totally 55 horses from Kinak and 24 horses from Kikav were observed as the sample size. The inbreeding coefficient was calculated using of pedigree analysis and inbreeding rate per generation based on the population structure. The result of inbreeding coefficient was 0,099 and 0,091 for Kinak and Kikav population while the inbreeding rate was 2,89% and 0,34% per generation, respectively. Mean of withers height and birth weight foals in last decade was 90,656±4,097 cm and 38,551±3,060 kg. Coefficient and inbreeding rate in Denkavkud didn’t decrease withers height and birth weight foals. There is no depression inbreeding, because it is following by selection.
