Judul: Pengaruh Jenis Slat Kandang Panggung terhadap Cedera dan Performa Produksi Ayam Broiler
Abstrak: Cedera yang dapat ditimbulkan oleh lantai slat yang digunakan pada ayam broiler adalah Foot Pad Lession, Hock Burn, dan Breast Blister. Cedera yang terjadi pada ayam broiler akan berdampak pada penurunan produksi daging. Penelitian ini bertujuan mengevaluasi rataan cedera dan performa produksi ayam pedaging yang dipelihara di kandang panggung dengan jenis/bahan slat yang berbeda. Penelitian menggunakan ayam pedaging strain Jumbo 747 Hijau dari PT. Cibadak Indah Sari Farm. Variabel yang diukur adalah cedera dan performa produksi. Pengukuran dilakukan pada ayam berumur 35 hari. Data yang diperoleh dianalisis menggunakan uji T (Independent Samples T-test) untuk melihat pengaruh penggunaan slat konvensional dan slat plastik buatan pabrik terhadap performa produksi ayam broiler. Hasil penelitian menunjukkan penggunaan jenis slat yang berbeda hanya mempengaruhi persentase tingkat kejadian cedera Foot Pad Lesion (FPL) dan Hock Burn (HB), tetapi cedera tersebut tidak berpengaruh terhadap performa produksi (P>0,05). Konversi pakan yang lebih baik ditemukan pada slat konvensional dengan nilai sebesar 1,51. Mortalitas yang terjadi pada penelitian ini bukan disebabkan karena pengaruh jenis slat yang berbeda, melainkan faktor lain., Injuries that can be caused by slat floors used in broiler chickens are Foot Pad Lession, Hock Burn, and Breast Blister. Injuries that occur in broilers will have an impact on decreasing meat production. This study aims to evaluate the injury rate and production performance of broilers reared in stilt cages with different types/materials of slats. The study used the Jumbo 747 Hijau strain of broilers from PT. Cibadak Indah Sari Farm. The variables measured were injury and production performance. Measurements were made on 35 day old chickens. The data obtained were analyzed using the T test (Independent Samples T-test) to see the effect of using conventional slats and factory-made plastic slats on broiler production performance. The results showed that the use of different types of slats only affected the percentage of the incidence of Foot Pad Lesion (FPL) and Hock Burn (HB) injuries, but these injuries had no effect on production performance (P>0.05). Better feed conversion was found in conventional slats with a value of 1.51. The mortality that occurred in this study was not caused by the influence of different types of slat, but other factors.

Judul: Pengaruh Jenis Litter Terhadap Cedera dan Performa Produksi Ayam Broiler.
Abstrak: Pemeliharaan ayam broiler umumnya menggunakan sistem kandang dengan alas litter. Jenis bahan litter yang digunakan diduga dapat mempengaruhi performa produksi ayam broiler, seperti konsumsi pakan, pertambahan bobot badan, dan mortalitas. Kelemahan penggunaan alas litter, diantaranya sering terjadi Foot Pad Lesion (FPL) dan Breast Blister (BB). Oleh karena itu, diperlukan jenis litter yang tepat dalam pemeliharaan ayam broiler. Penelitian ini bertujuan mengkaji pengaruh jenis litter terhadap tingkat cedera dan performa produksi ayam broiler. Penelitian terdiri atas tiga jenis bahan litter, yaitu P1: litter sekam padi; P2: litter jerami padi; dan P3: litter serutan kayu. Masing-masing perlakuan terdiri atas tiga ulangan. Tiap ulangan terdiri atas delapan ekor ayam broiler. Data yang diperoleh dianalisis dengan Sidik Ragam (Analysis of Variance) dan Uji Tukey (Tukey Pairwise Comparisons) untuk mengetahui beda antar perlakuan dengan software Minitab 18. Hasil penelitian menunjukkan bahwa jenis litter berpengaruh terhadap tingkat kejadian cedera Foot Pad Lesion (FPL) dan bobot akhir, namun tidak berpengaruh pada Breast Blister (BB), konsumsi pakan, dan mortalitas ayam broiler. Tingkat kejadian FPL terendah terjadi pada perlakuan P3 (litter serutan kayu) dan bobot akhir tertinggi terjadi pada perlakuan P1 (litter sekam padi)., Effect of Litter Types on Injuries and Production Performance of Broiler Chicken. Supervised by RUDI AFNAN and RUKMIASIH. Maintenance of broiler chickens generally uses a cage system with a litter base. The litter material will affect the production performance of broiler chickens, such as feed consumption, body weight gain, and mortality. Weakness of litter use for broiler bedding are the frequent occurrence of Foot Pad Lesion (FPL) and Breast Blister (BB). Therefore, it is necessary to have a suitable type of litterin the maintenance of broilers. This study aims to examine the effect of litter type on injury and production performance of broiler chickens. There are three types of litter material treatment, namely P1: rice husk litter; P2: rice straw litter; and P3: wood shavings litter with three repetitions. Each repetition consisted of 8 broilers. The data obtained were analyzed by variance (Analysis of Variance). The difference between treatments was subjected to the Tukey's Test (Tukey Pairwise Comparison) using Minitab 18 software. The results showed that the type of litter affected the incidence of Foot Pad Lesion (FPL) injury and final weight, but had no effect on Breast Blister (BB), feed consumption, and mortality of broiler chickens. The lowest incidence of FPL occurred in the P3 treatment (wood shavings litter) and the highest final weight occurred in the P1 treatment (rice husk litter).

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.
