Abstract

This research was done in order to diversify and to increase nutrition value of food product especially to enrich nutrition of fisheries product. Fish flour was made from Sardinella longiceps and wheat flour was used as materials to make crackers. The fish and wheat flour in the ratio of (0:100; 10:90; 20:80 and 30:70) were tested to get the best quality of crackers. Sensory quality, proximate analysis and texture test were applied in all products. The protein quality (chemical score) and calcium contents of the best crackers were 89.60 (limited amino acid : methionine) and 550 mg/100 g, respectively.The result of this research showed that the 20% fish flour-added crackers product had the highest rate of sensory quality (color, taste, smell, performance, and texture). It was accepted well by the panelists, and it also increased the protein quality and the calsium content.

Abstract

One of the estimating of density function which has been recognized is histogram. Histogram has some weaknesses, i.e. the different starting points and the width of class intervals. Different starting points or different class intervals result different histogram forms. This article is about the estimating of the density function by using kernel function. This method does not require the determination starting points and the interval class width. The obtained curve has a smooth density function, a small sampling variance, and the important information from data are still kept.

Abstract

Seafarming is an activity of culturing marine organisms, which encompasses broodstock selection, spawning, hatchery, juvenile culture, and mature stages. At the last stage, the fish, once resist to diseases and weather fluctuation, is released to water bodies for restocking purposes. Through restocking, fisherman's cathces are expected to increase in a sustainable manner. One of the technology that can be used for seafarming is grouper cage culture. This technology is quite productive and intensive, with net cages construction are anchored to float at coastal waters. Cage culture of grouper has a good prospective in Indonesia as the fish is highly valued in international market. Furthermore, Indonesia has very high potential coastal waters for grouper cage culture expansion

Abstract

Growth media waste of white oyster mushroom cultivation can be used as ruminant feed. We observed the nutrient content of the growth media waste. The focus is on the protein, carbohydrate, mineral and crude fiber. The protein, calcium and phosphor content of white oyster mushroom growth media waste is higher than the protein content in the media before it was used for mushroom cultivation. However, the fat content is lower after the media was used than control (the media before it was used). The difference is caused by microorganism degradation. The growth media waste can be used as ruminant feed up to 75 % of total forage dry matter without any negative effect.
