The purpose of this study was to optimize the bioethanol production from cassava pulp and cassava wastewater. The study was divided into two phase: 1.) Pretreatment and enzymatic hydrolysis 2.) Bioethanol fermentation. The effect of substrate and ratio of loading 1 3 5 and 7% (w/v) with the mixed enzyme α-amylase and glucoamylase ratio of 1:1 (v/v).The results showed that at 7% substrate loading the highest reducing sugar concentration was 89.55±1.13 g/L. Regarding the best ratio of α-amylase and glucoamylase at 1:1 (v/v) with fermentation time of 4 h gave the highest yield of 0.58±0.02 (g product/g substrate). In addition the highest glucose yield of 0.36±0.04 (g product/g substrate) was observed in 2 h fermentation time after hydrolysis with α-amylase and glucoamylase using cellulase and xylanase ratio of 1:1 (v/v). The results indicated that usage of mixed enzyme proved to spend shorter hydrolysis time and enhance the fermentable sugar production from cassava waste. The enzymatic hydrolysate was used as substrate for bioethanol fermentation using S.cerevisiaeTISTR5339. The results showed that the ethanol yield at fermentation time at 6 h with S.cerevisiae5 10 20 and 30% (v/v) were 0.27±0.027 0.23±0.002 0.19±0.022 and 0.16±0.011 (g ethanol/g substrate) respectively. The result indicated that ethanol yield decreased with increasing cell concentration of S.cerevisiaeTISTR5339 from 5% (v/v) to 30% (v/v).

This project was to case study: the pet dog pattern of His Majesty King Rama the 9th to embroidery design on the product. The purpose of this project was to study the pattern technique from 10 needles of single head embroidery machine and could embroidered pattern on the product. The dog pattern was the main pattern design and embroidered on indigo dyed fabric in Sakon Nakhon province. Then the bag prototype from indigo dyed fabric added the value to the indigo-dyed cotton product of villagers in the community. After that the questionnaire was to a sample. It found that the dog pattern design as a model that needed the most in this society. The satisfaction evaluation of textile product design with the dog pattern design was embroidered from 10 needles of single head embroidery machine on cotton indigo dyed fabric in Sakon Nakhon province with the inspiration came from the pet dog of His Majesty King Rama the 9th in the good lovingly of the pet dog named Khun Thong Dang. The product would reflect the nature of life on the earth as much as possible. The pattern of behavior pattern brought a playful dog. It looked like the natural that was suitable used for the pattern. The pattern was appropriate position. The material and color used the most suitable natural indigo dyed cotton product. The indigo colors were from nature. They were not harmful to life on the earth. The bag usage had the most suitable shape at 47 percent. The embroidered dog pattern bag product was the most durable to use at 43 percent.

This project was for the development of apparel accessories from indigo dyed fabrics in Sakon Nakhon Province. This project aims to bring indigo dyed fabrics to be developed into apparel products in UNISEX pattern so that it put on in everyday life and used all genders without restrictions. Today the sexual choices increase to introduce the concept of UNISEX pattern as an alternative. From the questionnaire the consumer needs the apparel accessories could be used in everyday life by using the principles of apparel accessories as a guide to design. Color tone used cool color (Cool Hues). 0The cool color was comfortable. The project maker chose to use indigo dyed fabric to make prototype products and also increase the value of indigo dyed fabric as well. 0 The samples used 100 people who interested in textile products at Chatuchak Market. The tools used questionnaires. The collected data were interview. The statistics used percentage. The study indicated that analysis assessed on the material shape products and the strength. Using silk indigo dyeing products were suitable in 78 percent and the material products were suitable in 42 percent. The shapes of products were suitable in the bag 64 percent and shoes 55 percent respectively. The product color was 64 percent and the durable strength for use in 52 percent.

This research is studying of an electric field combine with a frying process in a Chinese water chestnut product for reducing oil absorb. An electric field that is used in an experiment will have a stress from 1-3 kV/cm. This will be generated by using a direct current high Voltage from 1066 to 3200 V. which is distributed to an electrode in an uniform and non-uniform of an electric field. This will have a dielectric barrier discharge. There is an analysis for finding a relationship of a moisture on absorbing oil of a Chinese water chestnut fried product due to a moisture has an effect on absorbing oil directly. From an experimental result this is found that the best electric field stress which will have an effect on reducing a moisture of a Chinese water chestnut is an non-uniform electric field form that is created from a direct current high voltage at 3200 V. and this will have an electric field stress at 3 kV/cm. This will have an average of a difference of a moisture at 0.6 g. This will select to use a direct current non-uniform electric field at 3 kV/cm. In an experiment combine with a fried process in a Chinese water chestnuts fried product this is done for reducing of absorbing oil. By this will fry at the temperature of 180๐C for 5 minutes. This is found that this can reduce an absorbing of oil best at 17.93% when this has compared to a Chinese water chestnuts fried that hasn’t passed an electric field.

This study Motorcycle Tourism Potential of Kanchanaburi Province aims to study the motorbike tourism potential of Kanchanaburi. And suggestions for motorbike tourism development in Kanchanaburi Province. The research employed a quantitative research. The research sample was 400 tourists who travel by motorbike in Kanchanaburi tourist attractions. The research tools was a questionnaire with open-ended questions. The data is described by frequency percentage and standard deviation. Most participants were male 30-39 years old had obtained a bachelor degree managed private businesses and earned income of naked motorcycle. The results of the research indicate that opinions about motorcycle tourism potential in Kanchanaburi Province ranked from the highest to the lowest potential is travel cost Presentation and information view and the biker challenge of the route Security facilities of motorcycle tourism policy tourist attractions people motorcycle group and motorcycle club and marketing.
