Processing fish waste for extraction of value added products such as protein, lipid, gelatin, amino acids, collagen and oil has become one the most intriguing researches due to its valuable properties. In this study lipid from sardine was carried out using microwave-assisted (MAE) compared with Soxhlets Hara Radin methods. A mixture two organic solvents isopropanol/hexane distilled water were used MAE Meanwhile, Soxhlet method utilized only hexane solvent. The results show that higher yield...

Three types of microwave-assisted diluted solvents were employed using 0.1 N H2SO4 (MSA), NaOH (MSH), and 0.01 NaHCO3 (MSB). These evaluated as possible pretreatment routes for sago palm bark (SPB) with their effects on the pretreated substrate. A variety analyses, consisting fiber analysis, energy dispersive X-ray spectroscopy (EDX), fluorescence spectrometer (XRF), powder diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscope (SEM), high-performance liquid...

Solar energy is considered one of the most important renewable resources, and can be used to power a stand-alone photovoltaic (SAPV) system for supplying electricity in remote area. However, inconstancy unpredictable amounts solar radiation are major obstacles designing SAPV systems. Therefore, an accurate sizing method necessary apply order find optimal configuration fulfil required load demand. In this study, novel hybrid approach was developed on basis techno-economic objectives optimally...

Abstract Extraction valuable products from fish waste such as protein, lipid has gained more research attention around the worldwide. In this study, a was subjected to approximate analysis determine nutritional composition includes lipid, and carbohydrates well moisture ash content. The included scales, fins, bones isolated Cyprinus carpi samples. samples were divided into three groups named G1, G2, G3.The results showed high protein content in highest value 27.3 % found (G3). of also...

The present work utilized a by-product of the starch industry in Malaysia, Sago bark waste (SB), for pretreatment and enzymatic hydrolysis. SB was subjected to two types alkaline assess their effect on characteristic, inhibitor formation, hydrolysis sugar yield. Dilute sodium hydroxide (DSH) dilute bicarbonate (DSB) were used pretreatment. carried out conventional heating environment (120ºC) 10 min before step. results showed that treated by DSB resulted higher removal lignin (28%) compared...

In general, results revealed that average generation rate domestic was 0.85 Kg/capita/day area. organic found major components municipal it exceeded 60% composition. All dumping sites aforementioned uncontrolled dumpsite, their design not suitable, do work according...

Abstract Freshwater resources were suffered from the pollution problems that resulted pollutants of industries such as dyes and colourants. This study utilised a natural adsorbent, kaolin clay to remove pollutants’ dye (Methylene Blue) aqueous solutions. Batch studies conducted evaluate adsorption efficiency for removal solution under varying conditions initial pH (pH), contact time, concentration on dye. The optimum was found be 6. investigations in this showed 83% can achieved at first 50...

The removal of textile-based cationic methylene blue (MB) dye from synthetic wastewater was investigated in batch model using low cost agro-based adsorbents named Kenaf core, and the activated carbon. A comparative analysis between these defined via pH, adsorbent dose contact time on adsorption process, morphological properties. In addition, isotherms studies were estimated for determination equilibrium capacity. experimental observation showed that optimum pH values core carbon 6 4...

This study aims to evaluate the sugar yield from enzymatic hydrolysis and interactive effect pretreatment parameters of microwave-assisted on glucose xylose. Three types pretreatments sago palm bark (SPB) were conducted for hydrolysis, namely: microwave-sulphuric acid (MSA), microwave-sodium hydroxide (MSH), bicarbonate (MSB).
