Abstract Feed plays an important role in fish farming. Feed requirements achieve 60-70% of the cost of fish farming operations. Availability of feed with quality and sufficient quantity is aimed in increasing fish production. A very high feed prices due to artificial feed ingredients used are expensive and required in large quantities. Therefore, it is necessary to find alternatives to fish directly or indirectly obtaining appropiate and adequate nutrition needs to grow. The raw material content used for feed is coconut dregs (Cocos nucifera). The availability of the coconut dregs is abundant and potensial for fish feed ingredients. The coconut dregs is also one type or plantation waste which still has potential to be processed into the manufacture of fish feed. The coconut dregs flour can be processed by fermentation to improve quality. This study was aimed to determine the increase in crude protein content and a decrease in crude fiber content of coconut dregs fermented with Trichoderma viride; Bacillus subtilis and EM4. The research method was an experiment with Completely Randomized Design (CRD). The treatments used without the addition of microbes (P0), Bacillus subtilis 6% (P1), Trichoderma viride 6% (P2), and EM4 6% (P3) with 5 repeatitions each. The parameters observed were the content of crude protein and crude fiber after 7 days of fermentation. Data analysis used Analysis of Variance (ANOVA) and to determine the best treatments using Duncan Multiple Distance Test with 5% confidence interval. The results indicated that coconut dregs fermented with Bacillus subtilis (P1), Trichoderma viride (P2), and EM4 (P3) produced the difference of crude protein and fiber. The best treatment on the increase in crude protein content was Bacillus subtilis (P1) of 7.5564%. The best treatment on the decrease in crude fiber content was EM4 (P3) of 22.3967%. However, the results of the flour fermented coconut dregs can not be used as an alternative feed material because the fermented coconut dregs is not qualified for fish feed. This is due to a lack of crude protein and high crude fiber content.

Abstract 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.
