Judul: Gambaran sel darah merah ayam broiler yang diberi testosteron dosis bertingkat
Abstrak: Tingkat produktivitas ayam berhubungan erat dengan kondisi hematologisnya. Penelitian ini dilaksanakan untuk mengkaji pemberian testosteron terhadap karakteristik sel darah merah (jumlah eritrosit, kadar hemoglobin, dan nilai hematokrit ayam broiler). Penelitian ini menggunakan 12 ayam broiler berumur 15 hari yang dibagi dalam 4 kelompok (K, T1, T2, dan T3). K adalah kelompok kontrol, T1, T2, dan T3 adalah ayam broiler yang dilakukan pemberian 1, 2, dan 4 mg testosteron. Rancangan percobaan menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 3 ulangan. Analisis data dilakukan dengan ANOVA yang dilanjutkan dengan uji Duncan. Hasil penelitian ini menunjukkan bahwa testosteron berpengaruh nyata (p<0.05) terhadap jumlah sel darah merah, tetapi tidak berpengaruh nyata (p>0.05) terhadap kadar hemoglobin dan hematokrit. Dosis testosteron yang efektif untuk meningkatkan jumlah sel darah merah adalah 1 mg per ekor.

Judul: Gambaran Sel Darah Merah Ayam Broiler yang Diberi Testosteron Dosis Bertingkat
Abstrak: Productivity is closely related to chicken’s hematological conditions. The research was conducted to study the effect of testosterone given on the characteristics of red blood cells (erythrocytes number, haemoglobin level, and hematocrit values) of broiler chicken. 15 days of 12 broiler chickens were used in this study, with 4 groups (K, T1, T2, and T3). K was control groups, T1, T2, and T3 were broiler chicken which given 1, 2, and 4 mg testosteron respectively. The design of experiment using completely randomized design with 4 treatments and 3 replications. Data analysis was using ANOVA Duncan test. Our results showed that testosterone had significant effect (p <0.05) to the number of red blood cells, but it had no significant effect (p >0.05) to the amount of hemoglobin and hematocrit levels. Testosteron effective dose to increase erythrocytes number is 1 mg per 2 days (T1).

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.
