Judul: The Effect of Feeding Diet Containing Functional Biscuit Enriched with Catfish (Clarias gariepinus), Sweet Potatoes (Ipomoea sp.) Flours and ProbioticEnterococcus faecium IS-27526 Cream on the Profile of Fecal Microbiota of Female Aged Sprague Dawley Rats.
Abstrak: Administration of probiotic E. faecium IS-27526 cream of biscuit is expected to inhibit the growth of E.coli in the rats‟ intestine. Sweet potatoes may have prebiotic effect and helps the growth of good bacteria in the intestine. The aim of the study is to observe the effect of feeding diet containing functional biscuit cream probiotic E. faecium IS-27526 enriched with sweet potatoes and catfish flour on fecal microbiota of rats. Different composition of biscuit cream with and without sweet potatoes flour were administrated and 4 weeks feeding trial using Sprague Dawley rat was conducted in this study. The study assessed profile of fecal microbiota of rats. Administration of probiotic E. faecium IS- 27526 on biscuit cream tends to reduce the number of fecal coliform regardless of the presence of sweet potatoes flour. The presence of probiotic E. faecium IS- 27526 and sweet potato flour tend to increase fecal lactic acid bacteria as well as to reduce the fecal coliform of rats.

Abstrak: This study aimed to determine the effect of probiotic Enterococcus faecium IS-27526 and catfish ( Clarias gariepinus) oil in functional biscuit enriched with catfish flour and sweet potato (Ipomoea sp.) flour on fecal microbiota of aged monkey (Macaca fascicularis). There were 9 female aged Macaca fascicularis adapted for one month before the study, and divided into 3 groups, namely: control group, probiotic E. faecium IS-27526 group, and probiotic E. faecium IS-27526 and fish oil group. After 90 days administration, the fecal lactic acid bacteria in probiotic E. faecium IS-27526 group as well as probiotic E. faecium IS-27526 and fish oil group increased significantly (p < 0.05) as compared to the control group. The fecal coliform bacteria in probiotic E. faecium IS-27526 and fish oil group decreased significantly (p < 0.05) as compared to the control as well as probiotic E. faecium groups after 90 days.

Judul: Mencari Aproksimasi Akar-Akar Polinomial Kompleks Dengan Algoritma Weyl
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
