Judul: Gambaran Sel Darah Merah Ayam Broiler yang Diberi SirupTemulawak (Curcuma xanthorrizha ROXB.) Plus
Abstrak: Curcuma is a herbal plant that contain xanthorrizol curcuminoid and volatile oil as its main active ingredient that are beneficial as antioxidant, antiinflammatory, and antitumor. The research was conducted to examine the influence of curcuma at various concentration levels1, 3, and 5 ppm on total red blood cells, hematocrit value and haemoglobin concentration of broiler chickens. Twenty day old chick were divided into 4 groups, each group consisted of 5 chickens. Group I was the control group that was not given any curcuma syrup, while group II, III, and IV were given curcuma syrup at the concentration of 1, 3, and 5 ppm for 21 days. Blood samplings were performed at week 1, 2, and 3. The control group had lower total red blood cells, haematocrit, and haemoglobin concentration than the other groups. It was concluded that curcuma plus (group III and IV) could increase total red blood cells of chickens and there was not significant effects in hematocrit value and haemoglobin concentrations

Judul: Gambaran histologis proventrikulus, duodenum, dan hati ayam broiler yang diberi ekstrak temulawak plus
Abstrak: The curcuma has so many therapeutic advantages such as hepatoprotection, anticarsinogenic, antimicrobial, antioxidant, antihyperlipimedic, and antiinflammatory agent. This research was aimed to know the histological changes of proventriculus, duodenum, and liver of broiler chicken which were given curcuma extract plus multivitamin. A total of 36 broiler chickens were divided into 4 groups (P0, P1, P2, and P3) with 3 replications in each group. P0 was the control group that was given aquadest, while P1, P2, and P3 were given curcuma extract plus at a dose of 1, 3, and 5 ppm, respectively. The treatment was given for 3 consecutive weeks. The observed variables were number of epithelial cells which were cleavaging in the mucosa of proventiculus, number of Goblet cells and Lieberkhun glands in the duodenum, and intact structure of hepatocyte in the liver. The curcuma extract plus influenced the proliferation of epithelial cells in the mucosa of proventriculus, increased the number of Goblet cells and Lieberkhun glands in duodenum, and prevented liver cell damage in the broiler chicken. This histological changes may improve the efficiency of feed digestibility and proventriculus and intestinal mucosal protection of the broiler chicken.

Judul: The Exploration of Discrete Logarithm over Finite Field GF(3m)
Abstrak: The security of many public~key algorithms is based on the problem of finding discrete logarithms. The generalized discrete logarithm problem is the following: given a finite cyclic group G of order n, a generator a of G, and an element fl E G, find the integer x, 0 ~ x ~ n - 1, such that 0: = fl. Algorithm for discrete logarithm problem focused on Menezes et al. (1997) that consist of exhaustive search algorithm, the baby-step giant-step algorithm, Pollard's rho algorithm, Pohlig-Hellman algorithm, and index-calculus algorithm. These algorithms are explorated to be used in discrete logarithm problem over finite field GF(3m ). The exploration also produces some algorithms, i.e. naif negative algorithm, baby-step mother-step algorithm, baby-step mother free-step algorithm, and baby-step free-step algorithm. All algorithms implemented using Maple 11. The Pohlig-Hellman and baby-step giant-step algorithms are efficient enough to be used in discrete logarithm problem over finite field GF(3m ) for m < 20.
