Judul: Sifat Fisik dan Organoleptik Sosis Asap dengan Bahan Baku Campuran Daging dan Lidah Sapi Selama Penyimpanan Dingin (4-8ºC)
Abstrak: Beef is a perishable animal product, there for it need further processing to increase it’s shelf life; such as sausage processing. The benefits of smoking in sausage production are as bactericidal agent, antioxidant agent, and flavor precursor. Quality of smoked product depend on kind of wood and ingredient on the smoked, such as carbonyl, phenol, acid and base organic. Cold storage at 2-10ºC temperature could maintenance shelf life of product. Completely randomized design with factorial pattern 3 x 3 with three replication was used in this experiment. The physical parameters which observed in this research were pH value, emulsion stability, hardness, color value and sensory evaluation of sausage. The result showed that physical characteristic of smoked sausage from beef mixed tongue was significantly differences (P<0,01) on emulsion stability and hardness. Cold storage also influenced on pH value of sausage. The sensory evaluations showed that was not difference color, flavor, texture, taste, and general appearance of sausage. Adding 30% beef tongue as main material could be used for sausage production

Judul: Karakteristik Kimia Sosis Asap dengan Bahan Baku Campuran Daging dan Lidah Sapi Selama Penyimpanan Dingin (4-8oC)
Abstrak: Smoked sausage is one of sausage which is smoked in processing. Smoked sausage can be made from any combination kind of meats, such as meat and beef tongue. Beef tongue has a high nutrition value, however, its utilizing still low. Smoke processing can improve sausage quality such as flavor and shelf-life during cold storage. The purpose of this research was to study the chemical characteristics of smoked sausage of beef meat and tongue mixture as based materials during cold storage. The observed variables were moisture, protein, fat, ash, carbohydrate and phenol content. The data was analyzed by using a block randomized design with 3x3 factorial and three periods manufacture of smoked sausage as block. The result of this research showed that mixture of beef meat and tongue and storage time could reduced protein content of smoked sausage. However, mixture of beef meat and tongue and storage time did not give significantly effects on moisture, fat, ash and carbohydrate content. Interaction between mixture of beef meat and tongue and storage time weren’t significantly different on overall of the observed variables. Phenol content of smoked sausage reduced after seven days cold storage.

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.
