The objectives of this research are to study the Development of Souvenirs from Soap Carving as Dipping Vegetables. the researcher aimed to investigate the target group’s satisfaction on Souvenirs from Soap Carving as Dipping Vegetables. The researcher examined five methods of soap making from plentiful soaps and then the researcher designed one drafting of soap carving method and determined the size of container for containing carved soap types of vegetable patterns of leaf patterns of flower dipping sauce container and dyeing colors. Then these aforementioned details of soap carving were considered by five experts and they chose the method of soap making and overall patterns for developing of a carved soap product as a souvenir adapting the technique of dipped vegetable carving. After that the products were the instrument for observing target’s group satisfaction amount 100 participants. The data were analyzed as means percentage and standard deviation. The results revealed that. Most experts have chosen the soap type no.5 given that soap texture is fine smooth sticky. The Almost of experts chose the 8 inches diameter of sphere containers. The vegetables that were chosen for carving were long cucumbers cucumbers carrots eggplants Thai eggplants white eggplants white turmeric and long beans. For the leaves carving the patterns of leaves were grooving and stencil. The patterns of flowers carving were single layer flower pattern alternating flower pattern and long shaped flower pattern. Along with the pattern of container carving for chilling paste was the container with lid pattern and the colors for soap painting was batik dyeing color. The satisfaction level of the target group toward the product The highest level of an average of 4.82 for the elegance of the product. The creativity of the materials is at the highest level of an average of 4.74. The value and utility of the product for a souvenir are at the highest level with an average of 4.90.

This research focuses on the raw-material management such as fuel of a case study company being a freight forwarder in Chonburi province. The objective is to determine the economic order quantity (EOQ) and the reorder point (ROP) that minimize the total cost of handling. Five forecasting techniques are investigated to predict the future demand and it was found that the time series decomposition was the most suitable method with the least error. At the result of demand forecasting the economic order quantity is 16308.89 liters per time the total cost of handling the fuel tank is 17287.43 baht and there are ordering around 19 times per year. In addition the sensitivity study on demand factors affecting the cost of fuel tank management are also considered in this paper. It was found that 21% of the increased fuel demand brings the total handling cost is 1728.74 baht or increasing 10%. Therefore ordering economically can reduce the total cost of 1295.97 baht or 6.85%. If the company brings the studied results to improve the ordering process it will be able to forecast the order quantity more appropriately and effectively.

This study was conducted to determine the effects of plant growth regulators on in vitro propagated plantlets and microrhizome inductions of Curcuma comosa Roxb. for an efficient development of plant regeneration. In vitro sprouted shoots (2 cm length) of C. comosa were incised in longitudinal section and subcultured on MS media supplemented with 3 mg/L BA for shoot multiplication and plant regeneration. Subsequently the regenerated plants were transferred to MS medium with various concentrations of plant growth regulators; BA (1 3 5 mg/L) kinetin (1 3 5 mg/L) and TDZ (0.5 1 1.5 mg/L). The result showed that MS medium supplemented with 3 mg/L BA was the most effective in shoot induction with the significantly maximum average number of 2.11 shoot buds per responding explant. Moreover MS medium supplemented with 1 mg/L BA produced the longest average of shoot bud explants (12.99 cm) while the basal MS medium induced the longest average of root multiplication (6.63 cm). Furthermore microrhizome induction was produced under in vitro conditions derived young shoot buds upon transfer to MS medium containing various combinations of 1 3 and 5 mg/L BA and 30 60 and 90 g/L sucrose concentrations. The optimum combination in the induction of significantly highest average length of both stem (18.32 cm) and root (7.52 cm) multiplication was obtained on MS basal medium supplemented with 1 mg/L BA and 30 g/L sucrose for 4 weeks. Although microrhizome formation was not produced by the different amount of BA and sucrose in induction medium starch accumulation was found at the base of the stem explants cultured on MS medium containing 60 and 90 g/L sucrose concentrations. Additionally in vitro propagated C. comosa plantlets through microrhizome induction were grown under greenhouse conditions for 4 weeks and further developed into normal plants resulting in successfully high survival rates of 66 – 100% in the cultivated C. comosa.

The aim of this study is developed of alkali activated high calcium fly ash to use as cementitious material to replace Portland cement. The mixture of mortar made from fly ash and sodium hydroxide solution (NaOH) was used to activate strength at concentrations of 2 4 6 and 8 molars. Superplasticizer was used to control the flow of mortar in the rage of 105 – 110. The compressive strength of mortar was determined at 7 28 45 and 60 days. The acid resistance of mortars due to sulfuric at a concentration of 3% were also investigated. The results showed the mortar made from high calcium fly ash with sodium hydroxide of 6 molar obtained the highest compressive strength which could be developed compressive strength up to 189 ksc at 60 days. For the acid resistance of mortar it was found that the of use 6 molar of NaOH activated high calcium fly ash binder had the least weight loss due to sulfuric acid attack.
