Judul: Pengaruh pencucian daging dan penambahan otak sapi terhadap kandungan nutrisi dan palatabilitas pasta daging sapi
Abstrak: Leaching and adding of cow brain were tried on this research to improving quality of beef paste. Leaching wdd increase myofibrillar proteins c o ~ l r a t i o nan d adding of cow brain could improve textme of beef paste. The objectives of the research were to bow the effect of leaching and adding of cow brain to the nuhient content and palatability of beef paste. Completely mdornized designs with factorial treatments were used in this research. There were leaching (leaching vs. unleaching) and adding of cow brain (W, 15% 30% and 45%) as factor of treatments with three replications. Data were analyzed with ANOVA. There were no differences on treatments on nutrient content of beef paste. Hedonic test were significant differences on textures (PQ),05), and spread ability (PQ),Ol). Beef paste with cow brain (15% 30% and 45%) was most preferred.

Judul: Sifat Fisik dan Palatabilitas Pasta Daging Kambing dengan Metode Kominusi dan Frekuensi Leaching yang Berbeda
Abstrak: Goat (Capra sp.) as one of small ruminant animal has been domesticated in some countries, including Indonesia. Mutton is less acceptable by consumer due to its goaty smell, even though -as a protein source- contain essential amino acids which are needed by human body. By that means, mutton process in limited ways and resulting limited products. Leaching technique and comminuting method (a method which is reducing meat particle size), are some of technique to reduce or eliminate goaty smell in mutton. The aim of the research was to study physical characteristic and palatability of mutton pasta processed by comminuting method and different leaching frequency. The research used Complete Randomized Design Factorial Pattern with three repetitions. The first factor (A) was comminuting method consist of ground meat and small cutting meat (1.5x1.5x1.5 cm3 in size). The second factor (B) was leaching frequency which had three levels frequency: 0, 3 and 6 times. Data was analyzed by Analysis of Variants continued to Least Significant Mean if the results gave different effect. Observed parameters were color, aroma, texture, taste and spread ability, was evaluated by hedonic test using 50 panelists inexperienced. Data analyzed by Kruskal-Wallis Test and if it gave different effect continued to Rank Mean Compared Test. The research’s results showed that interaction between comminuting method and leaching frequency gave significant different effect to emulsion stability of mutton pasta.

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.
