Judul: Kualitas Fisik dan Kimia serta Mikrobiologi Sosis Fermentasi dari Daging Tetelan Sapi Selama Penyimpanan Suhu Dingin
Abstrak: Meat is packaged with protein containg all 23 essential amino acids which are important for body. The economic value of foursquer might be significantly enchanced by the processing, such as sausage fermentation. The purpose of this research was to study the physics, chemistry and microbiology characteristics of fermented sausage in cold stroge. The experimental design was used a factorial CRD (2x5) and analyzed used parametric analysis of variance test (ANOVA). The results of measurements of physical properties (pH, TAT, aw), chemical (moisture content and ash) and microbiology (fermented sausages with at of Lactobacillus plantarum 2B4 and Lactobacillus achidophilus 2C1 were not significantly different. Fermented sausages, is still good quality until H28 of with the at of L. acidophillus 2B4 . Amount of lactic acid bacteria qualify as a food source of probiotics that can be applied as starter cultures in the manufacture of probiotic fermented sausages.

Judul: Karakteristik Sifat Fisik, Kimia, Dan  Organoleptik Sosis  Sapi Dengan Pe rendaman Dalam Substrat  Antimikroba  Lactobacillus sp.  (1A5) Pada Penyimpanan  Suhu Dingin
Abstrak: Sausages are a food product that has been consumed by many people in the world. Sausages are normally processed with nitrite in order to keep them endure longer before they are consumed. After further study has been conducted, it is now known that nitrite contains elements that are carcinogenic, therefore further researches has been conducted to find an alternative for nitrite as a food preservative. Antimicrobial Subtract from Lactic Acid Bacteria Lactobacillus sp. (1A5) are suspected to be a natural form of alternative preservatives. Those conducted research are designed to study and explore the sausages physical, chemical, and sensory characteristics of the product, with submersion the sausages in antimicrobial subtract, then storing them at different period of time in refrigerated storage. This research gave a variety of result. The pH and peroxide level were very influenced by those two methods, while the water absorption was influenced by the different period of time method, only. Those two methods were not significantly affected to physical and chemical component. The sensory test has a different result in every criteria of quality, except the ooze level and firmness that are not significantly different.

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
