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: igenvalues and Eigenvectors of Tridiagonal Matrix with Non Constant and Recurrent Diagonal Entries.
Abstrak: Matriks tridiagonal adalah suatu matriks yang mempunyai entri-entri bernilai nol kecuali pada diagonal utama, di bawah diagonal utama (subdiagonal) dan di atas diagonal utama (superdiagonal). Entri pada diagonal utama tidak konstan dan berulang. Setiap entri pada matriks tridiagonal ini adalah bilangan kompleks. Dalam karya ilmiah ini, akan dibuktikan 3 teorema untuk menentukan nilai eigen dengan 2 kasus dan 1 teorema untuk menentukan vektor eigen. Teorema pertama menentukan polinomial karakteristik dari matriks tridiagonal. Polinomial karakteristik dari matriks tridiagonal tersebut digunakan untuk menentukan nilai eigen pada teorema kedua dan ketiga serta menentukan vektor eigen pada teorema keempat
