Judul: Pengaruh Ekstrak Akar Kayu Kuning (Coscinium fenestratum) dengan Pelarut Etanol Terhadap Gambaran Leukosit Mencit yang Diinfeksi Plasmodium berghei
Abstrak: The research was aimed to determine the effect of Coscinium fenestratum root extracts with ethanol solvent on leucocyte profile in mice infected with Plasmodium berghei. This research used 25 male mices that infected with P. berghei and divided into five groups of mice with five mices in each group, 1) Negative Control (given with Pulvis Gum Arabic soluble), 2) Positive Control (given with chloroquine), 3) E1 (ethanol extracts C. fenestratum with dosage 0.625 mg/25 gr BB), 4) E2 (ethanol extracts C. fenestratum with dosage 1.25 mg/25 gr BB), 5) E3 (ethanol extracts C. fenestratum with dosage 3.75 mg/ 25 gr BB). The research was used completely randomized design with five times repetition. The result showed that C. fenestratum root extracts with ethanol, the neutrophil percentage in all treatment was lower than negative control until 7th day after given extract. The eosinophil percentage was not show significant defferent. The monocyte percentage all treatment was lower than negative control at 2nd day until 7th day after given extract. The lymphocyte percentage all treatment was higher than negative control until 7th day after given extract. The basophil percentage in all treatment was not show significant defferent with negative control.

Abstrak: This research was conducted to determine the effect of Coscinium fenestratum root with water extract to the percentage of differential leucocyte mice that had been infected by Plasmodium berghei. This research used totally 25 male mice (Mus musculus), the mice then completely randomized devided into 5 groups and was design using three treatment groups. The five groups were 1) negative control group, 2) positive control group, 3) Doses 1 group extract (C.fenestratum root extract with doses of 0.625 mg/ 25grBB), 4) Doses 2 group extract (C. fenestratum root extract with doses of 1.25 mg/ 25grBB), and 5) Doses 3 group extract (C.fenestratum root extract with doses of 3.75 mg/ 25grBB). In male mice, highest percentage of neutrophil was doses 1 on 1st day after infection (58.40%), highest percentage of eosinophil was doses 1 on 7th day after infection (1.66%), highest percentage of monocyte was doses 1 on 7th day after infection (5.00%), highest percentage of lymphocyte was doses 3 on 3rd day after infection (57.46%), and highest percentage basophil was doses 3 on 7th day after infection (1%)

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.
