Judul: Uji Daya Hasil 12 Hibrida Harapan Jagung Manis (Zea mays L. var. saccharata) di Kabupaten Maros, Sulawesi Selatan.
Abstrak: Penelitian ini dilakukan untuk memperoleh informasi tentang daya hasil dan kualitas hasil 12 hibrida harapan jagung manis hasil seleksi tim peneliti gabungan Institut Pertanian Bogor dan Balai Penelitian Tanaman Serealia. Hipotesis yang digunakan dalam penelitian ini adalah terdapat perbedaan daya hasil, kualitas, dan keragaan hibrida jagung manis yang diuji dengan varietasvarietas pembanding serta terdapat hibrida harapan yang berpotensi untuk dikembangkan menjadi varietas baru. Penelitian ini dilaksanakan di Kebun Percobaan Balai Penelitian Tanaman Serealia, Maros, Sulawesi Selatan, pada bulan Juni – Agustus 2011. Bahan tanaman yang digunakan dalam penelitian ini adalah 12 hibrida harapan jagung manis, yaitu: IM-12, IM-13, IM-14, IM-15, IM-16, IM-23, IM-24, IM-25, IM-34, IM-35, IM-45, dan IM-55. Varietas pembanding yang digunakan adalah varietas Super Sweet Corn, Sweet Boy, dan Talenta. Rancangan yang digunakan adalah Rancangan Acak Kelompok Teracak (RKLT) dengan satu faktor perlakuan yaitu genotipe. Uji F digunakan untuk menganalisis pengaruh perlakuan. Jika terdapat pengaruh yang nyata dalam perlakuan, maka dilakukan uji nilai tengah menggunakan uji Dunnett pada taraf 5%. Analasis gabungan digunakan untuk mempelajari interaksi antara perlakuan genotipe dengan musim dan menduga nilai heritabilitas dalam arti luas. Analisis ini menggabungkan data hasil penelitian tahun ini dengan data primer hasil penelitian yang sama pada bulan April – Juni 2010. Uji Bartlett dengan software Minitab 14 dilakukan untuk mengetahui kehomogenan ragam galat pada kedua musim sebelum dilakukan analisis gabungan. Analisis ragam gabungan dilakukan terhadap 11 hibrida harapan dan satu varietas pembanding (Sweet Boy) yang diulang sebanyak dua kali dari masing-masing musim. iii Hasil percobaan menunjukkan bahwa perlakuan hibrida harapan berpengaruh nyata terhadap tinggi tongkol utama, umur muncul tassel, umur muncul rambut, umur panen, bobot berkelobot per tongkol, panjang tongkol, jumlah baris pada tongkol, jumlah biji per baris pada tongkol, jumlah tongkol per plot, jumlah tanaman menghasilkan per plot, kadar PTT, indeks panen tongkol berkelobot, dan indeks panen tongkol tanpa kelobot, tetapi tidak berpengaruh nyata terhadap karakter utama, yaitu produktivitas ...

Abstrak: The objective of this research was to evaluate yield potential of 12 sweet corn promising hybrids from Plant Breeding Program (Bogor Agricultural University) and Indonesian Cereals Research Institute selection.. The hypothesis was there are differences between the promising hybrids and commercial varieties about the yield, quality, and vigorness. This research was conducted at experimental field Indonesian Cereals Research Institute, in Maros, South Sulawesi, from June to August 2011. The genotypes used were : IM-12, IM-13, IM-14, IM-15, IM-16, IM-23, IM-24, IM-25, IM- 34, IM-35, IM-45, IM-55, and three comercial varieties Super Sweet Corn, Sweet Boy, and Talenta. The design of this research was Randomized Complete Block Design with four replications. Data was alayzed with F-test then continued with Dunnett test (α=5%). Furthermore, selection index was used for choosing the best genotype. Interaction between two factors, genotype and year, was analyzed with Bartlett-test then continued with F-test using primary data from this year research and last year research (was done from April to June 2010). Broad heritability was estimated from this twofactors analysis. The result from this research was the main character in sweet corn, the productivity, was not affected by genotype, but there was interaction between genotype and year. The other main character, total soluble solid, was affected by genotype, but there was no interaction between genotype and year. From selection index was gotten that IM-16 promising hybrid has the highest value and can be developed into newest commercial variety. The variable character that has highest board heritability estimation was total soluble solid.

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.
