Judul: Penambahan Minyak Biji Bunga Matahari pada Ransum Induk Domba terhadap Kecernaan Zat Makanan dan Komposisi susu.
Abstrak: A study was conducted using sheep to observe and to evaluate the quality of ration with different sunflower seed oil on digestibility nutrients and milk composition. This study used Completely Randomized Design (CRD) with 4 treatments, ie P0 (without the addition of sunflower seed oil or control), P1 (the addition of sunflower seed oil at 2%), P2 (the addition of sunflower seed oil at 4%), P3 (the addition of sunflower oil at 6%) and 3 replications. The data obtained from the study were analyzed using analysis of variance (Analysis of Variance/ANOVA) and when the result of the analysis showed significant differences, it will be followed by Ortogonal Polynomial Test. The result showed that the treatments did not significantly effect (P>0.05) nutrient digestibility, total digestibility nutrient, absorpstion minerals (Ca and P) and milk composition. The treatments significantly effect (P<0.01) fat intake. The addition of 6% sunflower oil has not affected the digestibility of nutrients and milk composition

Abstrak: The aim of this research was to determine the optimal level of sunflower seed oil in the diet that evaluated through measurement of nutrient digestibility in Garut ewes at the middle period of pregnancy. This research used completely randomized design and divided into four treatments. The treatments were P0 (without sunflower seed oil), P1 (2% of sunflower seed oil), P2 (4% of sunflower seed oil) and P3 (6% of sunflower seed oil). Data were analyzed by analysis of variance and any significant differences were further tested using polynomial orthogonal. The result showed that the treatments did not affect the consumption and digestibility of dry matter, crude protein, crude fiber, N-free extract, total digestible nutrients, average daily gain and feed efficiency, but its significantly affected (P<0.05) the consumption and digestibility of crude fat. It is concluded that the use of sunflower seed oil at 4% level could increase the consumption and digestibility of crude fat.

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.
