Pengaruh Beberapa Jenis Karbohidrat Dalam Pakan Terhadap Pertumbuhan Benih Gurami (Osphronemus Goramy Lac.) Yang Berumur Diatas 80 Hari [the Effect of Some Carbohydrates in the Diet on the Growth of Giant Gouramy Fry, Osphronemus Goramy Lac. Above 80 Days Old]

When small giant gouramy fry, 40 to 80 days old can consume carbohydrate diet, starch but his growth slow. Conversely, when he consumes simple carbohydrate, his growth is faster. Considering that feedstuffs derive from plants containning much complex carbohydrates like starch that is easier obtained and relatively cheaper price, so, it is important to study utilization of the starch as feedstuff on the diet of the giant gouramy fry. This research was carried out to find out type of carbohydrate that is suitable for giant gouramy fry above 80 days old. For achieving this purpose, it was important to test utilization of the diet containing starch compared with diet containing glucose, sucrose and dextrin on the growth of the giant gouramy fry. The giant gouramy fry was fed diet containing 27.68 % of glucose, sucrose, dextrin and starch each. The Feedstuffs in the diet were composed isocalorie and isoprotein. The giant gouramy fry that tested was 130 days old and average weight 6.90 grams. The fishes were cultured with stocking rate 5 fishes per 60 litre of water and cultured for 60 days. The diet that contains starch resulted the same on daily average growth rate to compare glucose, sucrose and dextrin ( P > 0.05 ). Sucrose diet resulted protein retention, lipid retention and energy retention higher than starch diet ( P < 0.01 ). Starch diet resulted the lowest retention of protein, lipid and energi ( P < 0.01 ). It was concluded that the sucrose was the best carbohydrate source for the giant gouramy fry, 130 to 190 days old. The starch was not suitable yet as source of carbohydrate to compose diet of the giant gouramy fry, 130 to 190 days old or average weigh 6.90 to 16.50 gram

Daya Antibakteri Sari Buah Majapahit (Crescentia Cujete L.) Terhadap Bakteri Aeromonas Salmonicida Secara in Vitro [Antibacterial Activity of the Juice Majapahit Fruit (Crescentia Cujete L.) to Bacteria Aeromonas Salmonicida Against in Vitro]

Bacteria are single-celled organisms, reproduce by dividing themselves (asexual) that reproduce by way of extending the cell nucleus followed by cell division called binary fission (Prajitno, 2005) and can only be viewed with a microscope because of their small size (Dwijoseputro, 1989 .) One of the bacteria that cause the greatest failures in the cultivation of freshwater fish and sea water is furunculosis (presence of a number of furuncles at the same time) caused by the bacterium Aeromonas salmonicida (Cipriano and Bullock, 2001). A. salmonicida is divided into several subspecies, among others, A. salmonicida subspecies salmonicida, subspecies masoucida, subspecies achromogenes and subspecies smithia (Hiney and Olivier, 1999). Fish infected with these bacteria will show symptoms such as fish body color becomes darker, the ability to swim down, resulting haemorrhagic septicemia, the abdomen looks bloated, the eyes and slightly protruding damaged fish (exopthalmia), all damaged fins, and gills become pale and damaged (Buller, 2004). The method used in the research is experimental method. This study aims to determine whether fruit majapahit juice (C. cujete L.) has antibacterial power against bacteria A. salmonicida and find out whether or not sensitive majapahit juice (C. cujete L.) in inhibiting the growth of bacteria A. salmonicida with standard comparator antibiotic kanamycin. Research conducted at the Laboratory of Bacteriology Hall Fish Quarantine Airport Highway Ir. H. Juanda Street No.23, Semambung Village Sedati- Sidoarjo District, East Java Province in February 2011. The results showed that the juice majapahit (C. cujete L.) could inhibit bacterial growth of A. salmonicida against in vitro, but when compared with standard antibiotic kanamycin 30 µg still relatively insensitive to inhibit bacterial growth of A. salmonicida
