The purpose of this research was to develop bagasse packaging antagonizing fungi with turmeric extract for Green Cos Lettuce cultivation. The bagasse package would incorporated with fungistatic turmeric extract instead of using chemicals at concentrations 0 5000 10000 15000 and 20000 ppm. The packaging characteristics efficiency of turmeric extract and the growth of Green Cos Lettuce determined into the percentage of germination height measurement fungi contamination characteristic were tested under the presence and absent antifungal bagasse The plant seedling spreading onto the surface of the packaging with turmeric extracts could be excelled for -their growth with the induction of germination rate of 92-97 percentages. Turmeric extracts at concentrations of 15000 and 20000 ppm had also expel the emergence of Penicillum sp. inhibit Rhizopus sp. and slow down Colletotrichum sp. Moreover the turmeric extract caused packaging decaying by itself slowly possibly helping in common airborne mold prevention. This green safe material showed the respectably effective for Green Cos Lettuce seedling especially for the fungal pathogen contamination during implantations. This research based on using natural extracts and natural fibers from agricultural waste is thus being ecofriendly nonchemical application of packaging product with easily digested for decent consumers who love their health and care environment.

Properties of pumice aggregate mortar blended with para rubber wood fly ash (PRWFA) replaced type 1 ordinary Portland cement (OPC) in different proportions of 020 and 40 wt.% OPC and dosed with used engine oil (UEO) in proportions of 00.2 and 0.3 wt% water were investigated. Whole mix type specimens size was cast in 555 cm and curing in ambient temperature for 7 and 28 days. Testing series of physico-mechanical properties performed on bulk density water absorption electrical resistivity Shore hardness and compressive strength were determined. Moreover microstructure via scanning electron microscope was analyzed. Effect of curing ages enhanced properties of samples such as electrical resistivity Shore hardness and compressive strength. Particularly the 28-day specimen that contained 20wt.% PRWFA and 0.2wt.% UEO provided bulk density of 1.61 g/cm3 and highest compressive strength of 22.09 MPa.

This research aims to develop the coconut coir and fiber indoor acoustic and thermal insulation boards mixed with natural latex. The 5 ratios of coconut coir: coconut fiber: natural rubber were equal to 0.1: 0.9: 0.1 0.1: 0.9: 0.15 0.1: 0.9: 0.2 0.1: 0.9: 0.25 and 0.1: 0.9: 0.3 by weight. The indoor acoustic and thermal insulation boards were produced by knitting the coconut coir and fiber spraying the natural latex and heat compressing. The properties testing of indoor acoustic and thermal insulation boards included the density test water absorption test tensile strength test thermal conductivity test sound protection efficiency test and real usage test. From the results 0.1: 0.9: 0.15 ratio is the most suitable ratio of coconut coir and fiber indoor acoustic and thermal insulation board mixed with natural latex. The natural latex which putted in these indoor acoustic and thermal insulation boards can reduce the water absorption and increase tensile strength and sound protection efficiency.

This research studied the efficiencies of ceramic membrane filtration from industrial asphalt for dyeing wastewater treatment by forming a ceramic membrane in a diameter of 6 cm height of 2 cm. An appropriate proportion of industrial ashes: kaolin: sodium hydroxide solution mixed with sodium silicate solution was 46:18:36 at 800 ° C. For the properties analysis of ceramic membrane made from industrial ashes found that a shrinkage value compression resistance and density water absorption value and permeate flux were found 3 percents 0.6 Kilonewtons per cubic centimeter and 1.93 grams per cubic centimeter 45 percents 8.61 milliliters per square centimeter per minute respectively. Structural surface by a scanning electron microscopy was found that the porous inside of material was closely aligned together. Moreover precipitation of synthetic wastewater by using industrial ashes could help to increase the efficiencies of dyeing wastewater treatment. From the experiment it was found that the precipitation of synthetic wastewater with industrial ash was 94 percent filtration efficiency. On the other hand the efficiencies of synthetic wastewater treatment without precipitating of industrial ashes found only 69 percent. Moreover this research offers a new option for industrial wastes utilization.

The objectives of this research were to study the effect of the substitution of sinin rice flour to wheat flour in the crust of the flaky Chinese pastry (Kha-Nom Pia Kularb) on the physical quality the chemical composition and the consumer acceptance of the developed product. The ratios of sinin rice flour substituted for wheat flour (w/w) at 0:100 (control) 10:90 20:80 30:70 and 40:60 were studied. The results showed that increasing substitution levels caused darker purple lower cohesiveness and more difficult for shaping. Additional the higher level of substitution the more decreased of product’s size specific volume and lightness (L*) of crust and filling. According to the texture profile analysis when the ratio of sinin rice flour in the product increased the hardness springiness and cohesiveness of the product decreased while the chewiness increased. Sensory quality evaluated with 9-point hedonic scale by 55 panelists. The crust of product which was formulated using a ratio of sinin rice flour: wheat flour at 20:80 had liking score higher than the others with moderate liking score. Analysis of chemical compositions (100 g product) showed that the contents of moisture protein fat ash carbohydrate and dietary fiber as 16.37 7.09 26.30 0.62 49.62 and 2.27 g respectively. The total calorie was calculated as 463..54 Kcal/100 g. Furthermore this product provided anthocyanin 6.5 mg/100g (dry basis). Moreover consumer acceptance test with 120 consumers revealed that the overall liking of this product was like highly and 98.0% of consumers accept it besides 96.7% of them decided to buy it.
