Judul: Aplikasi inseminasi buatan terhadap performa reproduksi imago betina ulat sutera liar Attacus atlas
Abstrak: Penelitian ini bertujuan untuk mempelajari pengaruh aplikasi inseminasi buatan terhadap performa reproduksi imago betina ulat sutera liar Attacus atlas. Penelitian menggunakan 28 ekor imago betina yang dibagi dalam dua perlakuan. Perlakuan pertama menggunakan 18 ekor imago yang diinseminasi dan perlakuan kedua menggunakan 10 ekor imago yang tidak diinseminasi. Hasil penelitian menunjukkan rerata bobot badan mati imago yang diinseminasi adalah 4.57±1.95 g, sedangkan imago yang tidak diinseminasi adalah 1.96±1.23 g. Rerata jumlah telur keluar imago yang diinseminasi adalah 51.61±84.02 butir lebih kecil dari imago yang tidak diinseminasi yaitu 235.20±145.71 butir. Rerata jumlah telur tertinggal pada imago yang diinseminasi adalah 207.06±82.92 butir dan 71.40±93.62 butir pada imago yang tidak diinseminasi. Rerata umur imago yang diinseminasi adalah 2.61±2.75 hari, lebih pendek dari imago yang tidak diinseminasi yaitu 9.50±2.42 hari. Aplikasi inseminasi buatan pada imago betina A. atlas menyebabkan peningkatan bobot badan mati dan jumlah telur tertinggal, penurunan jumlah telur yang dioviposisikan per hari, serta pemendekan umur imago.

Judul: Performa reproduksi imago jantan ulat sutera liar Attacus atlas L. (Lepidoptera: Saturniidae)
Abstrak: Attacus atlas L. (Lepidoptera: Saturniidae) is one of Indonesian native insect that has a great potential economy. Fulfillment the demand of material for silk thread still rely that exist in nature, therefore, needs to be done with the use of intensive breeding male imago as effective as possible in mating. The aim of this research was to study the reproduction performance of male imagoes of wild silkworm A. atlas. This research was conducted by allow a male imago mate with three different females. The time of each mating was 6 hours. The parameters observed were the first, second and third ejaculate volume, the number of eggs per imago, egg hatching time and hatchability of eggs. The results showed that the frequency of mating significantly affect the percentage of egg hatchability. The optimum value was achieved at first mating was 53.58 ± 18.26%. The percentage of egg hatchability declined with increasing frequency of mating. The number of eggs per imago and egg hatching time was not influenced by the frequency of mating with the average number of eggs per imago 225.86 ± 34.23 eggs and the average time of hatching eggs was 11.20 ± 3.23 days

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.
