Judul: Production and Quality of Chicken Eggs in  Different Multiple Cage Positions in Closed House System Cages at PT AS Putra  Layer
Abstrak: Pemeliharaan ayam petelur pada saat ini banyak beralih menggunakan kandang closed house, karena mampu meningkatkan produktivitas ternak. Penelitian ini dilakukan untuk mengkaji pengaruh posisi yang berbeda didalam kandang closed house terhadap performa produksi dan kualitas telur ayam strain hy-line brown. Peubah yang diamati adalah produksi telur terdiri dari hen day production (%HDP), bobot telur, dan kualitas telur terdiri dari haught unit, tebal kerabang dan warna telur. Penelitian ini menggunakan rancangan acak lengkap (RAL), posisi (depan, tengah, belakang) sebagai perlakuan dengan 6 ulangan. Data yang diperoleh dianalisis menggunakan ANOVA dan uji lanjut Duncan. Hasil pengamatan terhadap iklim mikro dalam kandang menunjukkan suhu tertinggi berada di posisi belakang, kelembaban tertinggi berada di posisi depan, kecepatan angin tertinggi berada di posisi belakang. Hasil perhitungan, suhu efektif dari ketiga posisi berada pada kisaran suhu nyaman, kondisi ini mungkin yang menyebabkan produksi telur dan kualitas telur yang dihasilkan tidak berbeda nyata.

Judul: Gambaran Darah dan Performa Produksi Ayam Kampung serta Ayam Ras Petelur pada Kandang Terbuka
Abstrak: Chickens need a cool ambient rearing temperature. Rearing chickens in open house on tropical regions such as Indonesia can cause physiological changes. Physiological conditions can be seen from the blood profile. Normal blood profile will support the achievement of optimal production. The aim of this research was to study the blood profile and its association with production aspect on kampung chicken and laying hen that were reared in open house . Blood profile parameters were including the number of erythrocytes, hematocrit, hemoglobin, leucocytes, and the percentage H/L ratio. Production performance parameters were feed intake, hen day production, egg weight, feed conversion, and mortality. The number of erythrocytes, hemoglobin, leucocytes of kampung chicken and laying hen were included in the normal range. H/L ratio of kampung chicken (1.45) was lower than laying hen (4.09). Feed consumption, hen day production, egg weight of kampung chicken were appropiate to standards, although its performance was lower than the laying hen. It can be concluded that kampung chicken better adapt than the laying hen, if it reared in open house with high ambient temperature

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.
