Judul: Physical Properties and Palatability of Meatball Made from Differences Slaughtered Ages of Duck Meat.
Abstrak: Indonesian farmer were kept duck fur meat and egg production. Most of duck meat were produce from old layer duck. Male duck also can be used as meat product. Duck meat were had specific odour that make this meat were unacceptable. Producing meatball with duck meat content were one of the solution to raising demand on duck meat. The research was conduct on May to August 2002 at Posat Pengkajian dan Penerapan Teknologi, Badan Pengkajian dan Penerapan Teknologi Budidaya Pertanian, Badan Pengkajian dan Penerapan Teknologi (BPPT), Rancamaya, Bogor, Laboratory of Large Ruminant, Faculty of Animal Science and Food Techoology Development Center (FIDC), Faculty of Agricultural Technology, Bogor Agricultural University. Duck meat from 7, 8, 9 and 10 weeks of slaughter age of Tegal male duck were used for meatball. Physical properties and palatability of meatball data were collected. Physical properties data were analyzed by ANOV A and Duncan test. Palatability data were analyzed by Kruskal-Wallis Nonparametric method and Gibbon test. Meatball pH and toughoess were influence by slaughter age. The pH value of meat from 10 week of Slaughter age were better than 7, 8 and 9 weeks of slaughter age (5.93 versus 7.17, 6.25 and 6.07 respectively) for producing meatball. The toughness of 8 weeks of slaughter age were the highest than other (0.52 versus 0.32 for 7, 9 and 10 weeks of slaughter age, respectively). Palatability of meatball from 10 weeks of slaughter age were had taste and toughness higher than 7, 8, and 9 weeks of slaughter age. Duck meat from 10 weeks of slaughter age were had good physical properties and palatabilities for producing meatbalL Key words: duck, meatball, slaughter age, pH, toughness, palatability.

Judul: Chemical and Sensory Properties of Fried Meatball Made from Rabbit Meat
Abstrak: Daging kelinci memiliki kandungan protein yang tinggi dan kolestrol yang rendah. Daging kelinci mempunyai serat yang halus dan bewarna sedikit pucat, sehingga daging kelinci digolongkan ke dalam daging bewarna putih seperti daging ayam. Penelitian ini bertujuan menguji sifat kimia dan organoleptik bakso goreng yang dibuat dari daging kelinci dengan penambahan tepung tapioka yang berbeda. Metode penelitian yang digunakan adalah rancangan acak lengkap (RAL) dengan dua perlakuan dan tiga kali ulangan. Faktor perlakuan yang diberikan dalam penelitian ini adalah 1.) A1 = daging kelinci 50% + 24% tepung tapioka dan 2.) A2 = daging kelinci 60% + 14% tepung tapioka. Hasil penelitian menunjukkan bahwa formula bakso goreng daging kelinci berpengaruh nyata (p<0,05) terhadap kadar abu dan kadar lemak, namun tidak berpengaruh nyata terhadap kadar air, protein, karbohidrat dan pH. Penggunaan daging kelinci 60% dengan tepung tapioka 14% menghasilkan kadar abu dan kadar lemak bakso goreng yang tinggi (p<0,05) daripada penggunaan daging kelinci 50% dengan tepung tapioka 24%. Berdasasrkan uji hedonik menunjukkan bahwa formula berpengaruh nyata (p<0,05) terhadap rasa dan tekstur, namun tidak berpengaruh nyata terhadap warna, aroma, dan penampilan keseluruhan. Pengujian mutu hedonik menunjukkan bahwa formula berpengaruh nyata (p<0,05) terhadap intensitas aroma bumbu dan intensitas keempukan. Penggunaan daging kelinci dengan taraf sebesar 60% menghasilkan mutu bakso yang lebih baik dibandingkan dengan penggunaan daging dengan taraf 50% berdasarkan kandungan gizi, rasa, dan tekstur pada bakso goreng daging kelinci., Rabbit meat is high in protein and low in cholesterol. Rabbit meat has fine fibers and is slightly pale in color, so rabbit meat is classified as white meat like chicken. This study aims to examine the chemical and organoleptic properties of fried meatballs made from rabbit meat with the addition of different tapioca flour. The research method used was a completely randomized design (CRD) with two treatments and three replications. The treatment factors given in this study were 1.) A1 = 50% rabbit meat + 24% tapioca flour and 2.) A2 = 60% rabbit meat + 14% tapioca flour. The results showed that the rabbit meat fried meatball formula had a significant (p<0.05) effect on ash content and fat content, but had no significant effect on water content, protein, carbohydrates and pH. The use of 60% rabbit meat with 14% tapioca flour resulted in higher ash content and fat content of fried meatballs (p<0.05) than the use of 50% rabbit meat with 24% tapioca flour. Based on the hedonic test, it showed that the formula had a significant effect (p<0.05) on taste and texture, but had no significant effect on color, aroma, and overall appearance. The hedonic quality test showed that the formula had a significant effect (p<0.05) on the intensity of the spice aroma and the intensity of tenderness. The use of rabbit meat with a level of 60% resulted in a better quality of meatballs compared to the use of meat with a level of 50% based on the nutritional content, taste, and texture of fried rabbit meatballs.

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.
