Suplementasi β-glucan dari ragi roti (Saccharomyces cerevisiae) dalam pakan terhadap aktivitas fagositosis, aktivitas NBT, total protein plasma dan aktivitas aglutinasi darah ikan nila (Orechromis niloticus)
Abstract. Tilapia is an important fisheries comodity which intesively farmed in Indonesia. However, an intensive farming system of aquatic organism often lead to disease outbreak. Ones the disease emerged, it will be difficult to combat. The curing method by using antibiotics in aquatic organism will bring negative impacts, such as causing bacteria resistance and decline of aquatic environments. Therefore control of disease in aquatic organism should be done through preventive methods such as the use of β-glucan from baker’s yeast (Saccharomyces cerevisiae). It is widely known that yeast’ cell wall contain of immunostimulant substance namely β-glucan. This research was aimed to find the effect of different dose of β-glucan in diet toward the phagocytic activity, respiratory burst which is indicated by Nitroblue Tetrazolium (NBT) activity, total of protein plasm and agglutination activity of tilapia blood. Method used in this study was experiment by complete random design using five treatments triplicate. Those treatments were β-glucan 0; 2,5; 5; 7,5 and 10 ppmkg-1 diet. Result showed that the different dose of β-glucan in diet gave a significantly effect on the phagocytic activity and total of protein plasm, but not on respiratory burst (NBT activity). The highest phagocytic activity occured in treatment E (β-glucan 10 ppmkg-1 diet) with the value of phagocytic activity was 37,67%, whereas the highest of total of protein plasm was occured in treatment B (β-glucan 2,5 ppmkg-1 diet) with the value of 123,58 mgml-1.

Science and Technology in Manufacture of Oyster Mushroom Seedlings
Oyster mushrooms (Pleurotus ostreatus) currently are in high demand because of their good taste and very high protein content. This nutritious and healthy food source make oyster mushrooms a preferable commodity in meeting food needs. It can be marked by the growing demand for oyster mushrooms while oyster mushroom production has not been able to meet the needs of the market, especially mushroom farmers in North Sumatra began to go from just farming by starting from a baglog that was ready to harvest, to providing its own seedlings. Farmers are expected to be able to produce initial seeds directly from fresh mushrooms that have commercial values. This program provides knowledge to farmers on how to develop seeds from fresh mushrooms to produce F-0, F-1, F-2 F-3 and finally baglog. Socialization, live demonstrations and interviews have been conducted by the team. Techniques for obtaining good seedlings by working with aseptic culture techniques and sterilization of growing media have also been given briefly to farmers. This program is expected that farmers have skills in producing seeds with subculture methods, as well as gain knowledge on using sterilization and aseptic techniques to be able to produce good and quality seeds
