Judul: Efektivitas Pemberian Kombinasi Herbal dengan Zink dalam Pakan terhadap Aktivitas dan Kapasitas Fagositosis Sel Polimorfonuklear pada Ayam Broiler yang Ditantang dengan Escherichia coli.
Abstrak: The aim of this research is to determine the phagocytosis activity and capacity of broiler that were given combination of herbal (turmeric and garlic) with zinc (Zn) that were challenged with Escherichia coli. One hundred sixty broilers divided into four treatment of groups which is R1 (basic feed + E. coli), R2 (basic feed + turmeric 1.5% + 180 ppm ZnO + E. coli), R3 (basic feed + garlic 2.5% + 180 ppm ZnO + E. coli) and R4 (basic feed + E. coli + antibiotic). The challenge of E. coli were done at the broiler has three weeks age. Blood sample was took at broiler has three weeks age (before challenged) and at broiler has five weeks age (after challenged). The result indicated that phagocytosis activity in the most highest, both before and after challenged there are in combination of turmeric-Zn, that is in the amount of 88.75% ± 11.30% (before challenged) and 97.75% ± 1.26% (after challenged). Phagocytosis capacity also indicated the result in the most highest in combination of turmeric Zn, that is in before challenged in the amount of 1746 ± 185 bacteria/50 cell and in after challenged in the amount of 2414 ± 264 bacteria/50 cell. this research conclude that activity and capacity of phagocytosis PMN cell in supplementation of combination turmeric with Zn higher than supplementation of combination garlic with Zn. Keywords: fagocitosis, E. coli, broiler, turmeric, garlic, zinc.

Judul: Pengaruh Formula Ekstrak 4 Tanaman terhadap Aktivitas dan Kapasitas Fagositosis Makrofag Peritoneum Ayam yang Ditantang dengan Bakteri Staphylococcus aureus
Abstrak: The purpose of this research is to observe the effects of four medicinal plants extract formulas (Temulawak/Curcuma xanthorriza Roxb., Temu Ireng/Curcuma aureginosa Roxb., Meniran/Phyllanthus niruri Linn., and Sambiloto/Andographis paniculata Nees) on chicken’s peritoneal macrophage activity and capacity by counting the number of active macrophage and the number of phagocytised bacteria. Fifteen heads of day old chick were divided into five groups with various treatments. The treatments were; (1) F1: extract combination of Temulawak, Temu Ireng, Meniran, and Sambiloto; (2) F2: extract combination of Temulawak, Temu Ireng, and Meniran; (3) F3: formula Temulawak and Temu Ireng; (4) F4: extract combination of Meniran and Sambiloto; and (5) untreated as control. The chikens were treated for 28 days. Result showed that all combinations of plant extract formula treatment increased the activity and capacity of chicken peritoneal macrophage compared to the control group. For activity, group F3 was the best result (p<0.01), while for capacity the group F4 give the highest response (p<0.01). In general we concluded that combination of Meniran and Sambiloto (group F4) was the best combination on chicken peritoneum macrophage activity and capacity.

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.
