Judul: Respon Fisiologis dan Kinerja Ayam Sentul Umur 9-12 Minggu pada Kandang Bersuhu Netral dan Tinggi
Abstrak: Sentul chicken is one of Indonesian native chicken from district of Ciamis which produced eggs and meat. Temperature may influence the physiological response, performance, and behavior of sentul chicken. Sentul chickens consisted of 48 males and females each were placed into two different room temperatures, i.e., neutral and hot. Each house was devided into four pens for male and female. Each pen consisted of six chickenswhich were raised at 23 oC and 30 oC. Variables measured were feed consumption, body weight gain, feed conversion, and mortality. Rectal temperature and panting were measured. Data were subjected to analysis of variance and any differences were continued to Tukey test. The result showed that rectal temperature was significantly affected by house temperature. Performance of chickens at temperature 30 oC was the same with chickens at temperature 23 oC. Panting behavior was observed only in house with heat treatment. There was no mortality in both housing temperature.

Judul: Respon Fisiologis dan Kinerja Ayam Sentul Umur 5-8 Minggu pada Kandang Bersuhu Netral dan Tinggi
Abstrak: A total of 96 Sentul chickens aged 5 to 8 weeks consist of 48 males and 48 females were used in this experiment. These chickens were kept in litter in semi closed house. The experiment was factorial complete randomized designed with sex (male and female) and housing temperature (23 °C dan 30 °C) as factors. Physiological responses (rectal temperature and panting) as well as productive performances (feed consumption, body weight gain, feed conversion, and mortality) were measured. The results showed that housing temperatures significantly affected the rectal temperature and panting. Feed intake was significantly differed between male and female as well as body weight gain (P < 0.05) with males intake and gain more than female. Feed conversion differed significantly between housing temperatures (P < 0.01). No mortality was observed during experiment. The chicken reared under neutral temperature revelead better productivity than those under high housing tempeterature.

Judul: Algoritme LLL dan Aplikasinya dalam Pembongkaran Sistemkripto Knapsack Merkle-Hellman
Abstrak: LLL algorithm is an algorithm that can be used to determine an approximation of the shortest vector in a lattice. Size reduction algorithm is an important step of LLL algorithm. The LLL algorithm can be applied in many elds. This paper shows how LLL algorithm can be used in breaking one of the famous cryptosystem, namely the Merkle-Hellman knapsack cryptosystem. Merkle-Hellman knapsack cryptosystem is an asymmetric cryptosystem using the subset sum problem as the support of security. Subset sum problem can be transformed into the problem of determining shortest vector in a lattice, so that LLL algorithm can also be used to solve the subset sum problem. Since the subset sum problem can be easily solved by applying LLL algorithm, then the Merkle-Hellman knapsack cryptosystem can also be easily be destructed.
