This research aims to study the application of cassava fiber. The fibers are taken from cassava and pineapple Head that 3 ratios are used to all of fiber mixing. The fiberboard production use 130°C of temperature with 20 – 50 kg/sq.cm of compressive pressure with 10 minutes per piece of rate. Their fiberboards have 681 – 724 kg/cu.m of density and 7.1 – 7.6 % of moisture. Resulting the CF 05 ratio (cassava: urea is equal to 0.95:0.13) is suitable ratio which has good physical and mechanical properties.

The objective of this research was to determine the formulation of soap for carving operations and study the satisfaction of developed carved-soap by carving person. There were 3 basic formulas of the soap e.g. olive oil formula (formula 1; 500 ml olive oil 60 g sodium hydroxide and 140 ml water) coconut oil formula (formula 2; 200 ml coconut oil 34 g sodium hydroxide and 80 ml water) and glycerin formula (formula 3; 200 g glycerin and 5 g sodium hydroxide). The basic formula 3 showed the highest satisfaction scores from carving person when compared with other formulas. The next experiment was to find the optimal temperature for heating the mixtures in the range of 40-60oC. The results showed that the temperature of 45oC was the best treatment for heating three types of soap mixtures. Moreover the formula 3 soap received the highest satisfaction scores ( X = 4.21-4.53) from carving person which had the good appearance exquisite styles shape and proportion right. There was no crack no visible of mold growth and soap powder on the product after caving operations. The satisfaction of 52 carving persons between the general soap and developed carved-soap for carving operations was studied using 5-point rating scales. The satisfaction scores of softness stickiness and aroma were significant different (p<0.05) between two types of soap. However the dryness/hardness silkiness color painting property and overall quality scores were not different. The suitable shape of soap for carving operations was a round shape followed by square shape oval shape and heart shape respectively.

The purpose of the development of dietary fiber supplement food from used coconut residue is to study an appropriate amount of used coconut residue from oil distillation in three food products such as steamed stuff bun deep-fried dough stick and roti. The research was planned in accordance with “Randomized Complete Block Design RCBD”. Sense test by tasting method by giving favorite scores of 9 levels (9 – Point Hedonic Scale) quality test of chemical composition and physical composition including acceptance test of 100 people towards the products were performed.

This research aims to develop and calculate the efficiency of electronic books injection mold design engineering for Plastic Mold Technology1 (04-812-313) The participants of this research were 40 third year students who enrolled in Plastic Mold Technology1 subjects in first semester 2013. The research tools were 1) an electronic books 2) a questionnaire for measure an efficiency of electronic books 3) an achievement test. Data were analyzed by using difficulty discrimination validity index of consistency The result showed that quality of electronic books injection mold design engineering was in a very good level with higher sufficiency mean = 1.13 than criteria at mean = 1 and was very useful for Plastic Mold Technology1 (04-812-313)

The aim of this research is to study white and colour resist printing of dye extracted from dry nipa palm shell. The printing recipes and fixation condition were studied in this work. The result of white resist printing showed that 30 % owp of sodium carbonate (Na2CO3) was used to be a resisting agent. The steam fixation for 15 minutes was suitable to show a good white resist printing in whiteness and sharpness of printing pattern. The whiteness value was 35.05. The washing and rubbing fastness were good to very good and light fastness was fair. The tensile strengths of warp and weft directions were decreased to 10.29 % and 4.25 % respectively. The colour resist printing was using Curcuma longa Linn. powder as illuminant dye. The dye was miscible in 30 % owp of sodium carbonate. The colour resist printing results were corresponding as white resist printing results. The 15 minute of steam fixation showed a good colour resist printing. The Curcuma longa Linn dye could be fixed on silk fabric and showed a good colour strength and sharpness of pattern. The washing and rubbing fastness were good to very good. And light fastness was fair. The tensile strengths of warp and weft directions were decreased to 18.37 % and 4.18 % respectively.
