The demand for amplang crackers is now increasing. However, the price of its raw material, mackerel fish, is generally higher compare to other fishes, causing the higher cost of this type crackers production. Effort to explore other fish as an alternative raw material is required to overcome the problems. Catfish is one of the choices to be used as raw material since this fish is more available in a market in a lower price, but the protein properties of this fish is different to mackarel, which will be possible to affect the nature of the crackers obtained. To produce catfish amplang crackers to be similar to common amplang product, it is necessary to find out the right composition of catfish and tapioca flour used. Therefore, the purpose of this research was to characterize physico-chemically and organoleptically, the catfish amplang crackers made under different ratio of fish flesh and starch. The experiment was designed using completely randomized design. Physico-chemical data obtained were analyzed using ANOVA, while the organoleptic test data were examined using chi-square method. The effectiveness test was carried out to find the proper ratio of raw materials composition used. The results showed that the higher the ratio of the fish flesh and the starch composition, the lower the texture value of the crackers as an indication of the decrease of its crispness. Although the lightness of the crackers was lowered by the addition of more starch to the dough, its linear expansion and hygroscopicity were not affected. The results of organoleptic test showed that the panelist was prefer to a higher crispness of crackers. The most preferable cracker was the one with 1:2.25 ratio of catfish flesh and starch, showing the characteristic of 1.80% moisture, 2.08% ash, 5.75% protein, 23.55% fat, and 66,93% carbohydrate. Keywords: cracker, catfish, tapioca starch

The Chicken broiler is a type of superior race chicken that has high genetic properties, especially in growth. The use of herbs as medicines in medicine is now starting to increase, which is evident from the many traditional drugs manufacturers on the market. One of the herbs that can be used as an antibiotic for livestock is basil (Ocimum sp). Basil contains beta-carotene (provitamin A), which supports the function of vision, improves antibody function (influences immune function), protein synthesis to support growth process and as the antioxidant (Adnyana and Firmansyah, 2006). The purpose of this study was to determine the effect of the addition of basil leaves flour up to 12% level against broiler performance. The experiment was carried out experimentally using a completely randomized design (CRD). The results of statistical analysis showed that the addition of basil meal powder into the feed did not affect to feed consumption between levels (P> 0). The result of the statistical analysis showed that the addition of basil meal powder into the feed had no effect (P> 0,05) to the increase in body weight. The result of the statistical analysis showed that the treatment with the addition of basil powder into the feed had no effect (P> 0,05) to feed conversion. The result of this research can be concluded that the addition of basil powder into feed up to 12% level did not give significantly different effect on production performance such as feed consumption, body weight gain and feed conversion of the broiler.

The economic value of the Abaca banana is on the trunk which contains fiber for valuable textile and paper industry raw materials. The multipurpose fiber and its prospects are quite good, so the abaca plant gets a lot of attention from various community groups both private, state-owned, cooperative and farmers. Propagation through multiplication humps is very low, planting material is easily damaged in transportation, is not durable and requires large space so that transportation costs are high. One alternative to overcome the provision of healthy, large and fast seedlings is to use seedlings from tissue culture. The aim of the study is to get the right thiamin and leaf fertilizer concentrations at the acclimatization stage. The experimental design used was a 2-factor Complete Randomized Design, Thiamin concentration (1 ml / l, 2 ml / l, 3 ml / l) and leaf fertilizer (0.5 ml / l, 1 ml / l, 1.5 ml / l). The data obtained were analyzed for diversity at 5% level and further tests using Duncan Multiple Range Test (DMRT) level of 5%. The results showed no interaction between thiamin and leaf fertilizer, Thiamin 2 ml / l gave the best results on all parameters and 1.5 ml / l leaf fertilizer could increase plant height and the number of leaves of abaca banana plants.Keywords: Thiamin, leaf fertilizer, abaca banana, acclimatization
