Research on the characteristics of seaweed Gelidium sp from Lampung waters and its agar has been done. This study aims to look at harvested by collectors produced. Seaweed is wild main producing area in Lampung, Krui. The quality parameters observed were moisture content, impurities clean anhydrous weed (CAW) as well yield. While gel strength, gelling point melting point. results showed that an...

Activated carbon is an elemental material used for hygienic applications, particularly as an adsorbent for harmful gases and vapors. In Japanese industrial and occupational hygiene, activated carbon produced from coconut shell is a traditional and popular adsorbent material due to its excellent adsorption ability and cost advantage. In this research, in order to clarify the effect of the prelim...

The differences on proximate composition, sensorial analysis (for raw and cooked samples) and flesh productivity of the samples of Parapenaus longirostris that were caught in the North Aegean Sea and Marmara Sea were investigated. Moisture, protein, lipid, ash, carbohydrate, energy content of the North Aegean Sea shrimp were found 74.92 ± 0.1, 20.32 ± 0.16, 2.55 ± 0.1, 2.13 ± 0.08, 0.08%, 110.1...

One of the most important design and operating parameters at composting facilities is moisture content. Existing standard gravimetric oven methods required a minimum of 19 hours to complete. In this study, by reducing the amount of sample, the time required to complete a standard gravimetric oven method was reduced to nine hours. A new infrared moisture balance method was also developed that re...

Extrusion is a continuous process and successful economic production depends on maintaining stable output and melt quality at an accurately controlled rate. Current screw design technology, the use of DC drives, computerized controllers and raw material testing help to deliver the melt to the extrusion die at relatively constant temperature, pressure and viscosity. However, even the slightest v...

In 2003–2006, micromycetes – potential producers of mycotoxins – were detected and their taxonomic dependence as well as ability to produce toxins under various growth conditions were assessed. Accumulation regularities of toxin-producing micromycetes in vegetables, fruit, berries, herbs, grain, seeds and their products were found out. Factors determining fungal abilities to produce various tox...

The effect of temperature on a very high gravity ethanol fermentation using no cook process was investigated. We found that a gradient temperature control strategy could improve the fermentation efficiency significantly, With the assistance of a new raw starch hydrolyzing enzyme and a gradient temperature control strategy, the ethanol concentration could reach up to 20% (V/V) within 90 h using ...

Abstract Renewable energy is an alternative to fossil fuels due the limited supply of and greenhouse gas emission contribution. Bioenergy one renewable energies that derived from biomass. Biomass waste, namely durian peel sewage sludge, has potential as raw material for bioenergy because its content. Moreover, carbonization biomass water can improve heating value material. This study aims inves...
