Abstrak: Housing temperature and housing system may influence productive performance and egg qualities. This research aimed to investigate the influence of different housing temperatures and housing system on productive performance and egg qualities. A total of 72 Lohmann hens were reared in litter and cage system with different housing temperatures of 18 oC and 30 oC. Each treatment consisted of 18 hens. Traits measured were productive performance (feed intake, hen day production, egg weight, egg mass, and feed conversion), egg internal and external qualities (egg shape index, Haugh Unit, air sack, albumin height, egg shell cleanless, egg shell thickness, and egg shell weight). This experiment was run twice according to housing system for each housing temperatures and was completely randomized design. Data was subjected to t-test and descriptive analyses. Productive production and egg quality in both housing systems did not differ. However, the egg weight was significantly heavier in cage system compared to litter system in neutral housing temperature.

Judul: Performa Ayam Ras Petelur pada Kandang Cage dan Litter.
Abstrak: One of the main tools that have to be considered for an intensive and efficient laying hens maintenance was cage aspect. The purpose of this research was to see the effect of cage treatment and the unit cost analysis of laying hens. The observed parameters were feed consumption, egg weight, feed ratio convertion, hen day production, egg exterior quality, and unit cost. The research was done by complete randomized design with two cage treatment and 6 replication that containing 16 (cage) and 25 (litter) laying hens each. The data was analized with Statistical Package for the Sosial Science (SPSS) programs by independent sample T-test. The result showed that the cage treatment has significantly differencies foward feed consumption, feed ratio convertion and eeg cleanliness with dirty level below 25%. The significantly differencies in egg weight and hen day have been showed in the first 2 and 3 observation weeks. The best unit cost was the laying hens mainternance in cage system.

Abstrak: Mencari akarMakar polinomial dengan menggunakan algoritma Weyt. Algoritma WeyJ merupakan algoritma rekursif yang proses kerjanya dapat diana10gkan dengan algoritma Bisection. Karena algoritma Weyl bergerak dalam bidang kompleks maka memerlukan nilai awal hempa bujur sangkar. Dalam proses penyempitan bujur sangkar tersebut algoritma Weyl memerlukan algorittna Turan untuk menentukan jarak antara suatu titik dengan akar polinomial yang terdekat dengan titik tersebut. Karena apabiJa jarak tersebut temyata lebih hesar dari Yl panjang diagonal bujur sangkar yang diamati maka bujur sangkar tersebut tidak memuat satu pun akar polinomial. Untuk seJanjutnya bujur sangkar tersebut diabaikan. Sebaliknya apabila jarak yang diperoleh lebih keeil dari \6 panjang diagonal bujur sangkar yang diamati, maka bujur sangkar tersebut yang akan diperkeciL
