Characterization of potential probiotic in digestive tract of Mugil cephalus (Linnaeus, 1758)
Probiotics are beneficial microbes in living things that are useful for improving the balance of microbes in the digestive tract and have a positive influence on the physiology and healthiness of the host. This study aimed to obtain bacterial isolates that could be used as probiotics from striped mullet (Mugil cephalus) and to characterize it macroscopically, microscopically, and biochemically. Isolation of probiotic bacteria was carried out using the spread plate method. The medium used to isolate probiotic bacteria was MRSA (De Man Rogose Sharpe Agar) medium. The probiotic test was carried out by hydrolysis of starch and casein. The diversity of bacterial morphology was observed based on macroscopic, microscopic, and biochemical tests. A total of 2 probiotic bacteria (PIB 1 and PIB 2) were obtained. The characterization results showed that the two probiotic bacteria belonged to the Gram-positive bacteria, in the form of bacilli which had different colony morphology. The results of morphological and biochemical tests indicated that one bacterial isolate belonged to the genus Bacillus (PIB 1) and the other isolate belonged to the genus Lactobacillus (PIB 2)

Pengaruh Formulasi Pakan Hijauan (Rumput Gajah, Kaliandra dan Gamal) terhadap Pertumbuhan dan Bobot Karkas Domba
The effect of forage formulation (elephant grass, kaliandra, and gamal leaves) on the growth and carcass of sheep
ABSTRACT. Feed is one of most important factors to increase animal production. Feeding animal with only one kind of grass such as elephant grass on ruminant animals including sheep is not able to increase the productivity of the animals. Kaliandra and gamal leaves contain high level of protein and can be formulated to ruminant nutrition. The purpose of this experiment is to evaluate the effect of forage namely elephant grass (Penisetum sp.), kaliandra (Caliandra calothyrsus), and gamal (Gliricidia sepium) on the growth and carcass of sheep. Forty nine sheep with the starting weight of 15,42 kg (SD 2,68) were used in this experiment and fed fresh elephant grass (RGS), fresh kaliandra (KS), dried kaliandra (KKR) and steamed kaliandra (KKS). Treatment A: 70 % RGS + 30 % KS, B: 70 % RGS + 30 % GS, C: 70 % RGS + 15 % KS + 15 % GS, D: 70 % RGS + 15 % KKR + 15 % GS, E: 70 % RGS + 15 % KKS + 15 % GS. Animals were fed for 70 days and given free access of water (ad libitum). Data collection was the growth of animals (average daily gain) and the weight of carcass. All data was analyzed by ANOVA. The results of the experiment show that forage formulation (fresh elephant grass, fresh, dried and steamed kaliandra and fresh gamal leaves) were not significantly effect on the growth and carcass of sheep
