This research focuses on the production of charcoal briquettes from agricultural residues by using durian and nypa palm peel mixtures. The objectives of this study are to study the combustion efficiency of charcoal briquettes; study the suitable ratio for the production of briquettes with the ratios of durian : nypa palm peel mixtures as 100:0 50:50 25:75 and 0:100; recycle the agricultural residues as the renewable energy sources and analyze the fuel characteristics; moisture content ash content volatile matters fixed carbon and heating value. The results showed that the best ratio for the combustion efficiency of charcoal briquettes is 50:50 with the minimum moisture content of 4.68% the minimum ash content of 2.70% the volatile matters of 10.33% ; the maximum fixed carbon of 25.56% and all characteristics are met with the standard of charcoal briquettes from the local community products. In the ratio of 100:0 it showed the maximum heating value as 5399 calories per gram. Therefore the 50:50 charcoal briquettes are suitable as the renewable energy source. Besides the capacity of odor adsorption was analyzed by adding the odor substances (mothball) in two bottles with three mothballs for each bottle for two consecutive days before removal. Then sic of 50:50 charcoal briquettes were added into one bottle. Ten testers smelled the bottle every two days for six days. The result showed that the bottle with the charcoal briquettes had odor less than the bottle without briquettes. Hence the charcoal briquettes from durian and nyla palm peel mixtures have the best odor adsorption capacity and are suitable for household uses.

The objectives of this study is to 1) study the behaviors of consumption of baked goods in Bangkhen district Bangkok and 2) study factors of decision making of consumers on services. We have sample of 400 subjects and used statistical methods consist of frequency proportion mean standard deviation t-test and F-test. From the results we found that most of the consumers are female of age between 20 – 30. Most of our samples are students and have income less than 10000 baht per month. For the results on behaviors we found that most purchases are for self-consumption. Cakes are the most popular baked goods. There’re 1 – 3 quantity of goods per purchase and cost around 70 -150 baht. The frequency that samples go to bakery is 1 – 4 times a week from Monday to Friday and around 15.01 – 19.00. Samples mostly got information of bakery from personal communication. The results show that price is the most important factors influence on consideration of consumers given ( = 4.46) of mean. While other important factors are products ( = 4.37) convenience ( = 4.10) brand loyalism ( = 4.05) commercial ( = 3.99) brand’s quality ( = 3.96) and brand ( = 3.85). There’s no difference on the influence of gender on consumption but there’s a significant difference between price and brand’s quality and between ages and between convenience and commercial.

The study on baked crispy okra sheets (Hit 9701 species) by using a hot air dryer. The objective of this study was to investigate the okra sheets formula and manufacturing procees by hot air dryers with 3 methods; pouring finely blended okra onto the inside tray pouring finely blended okra onto the outside tray and pouring finely blended okra into an aluminum block. It was found that pouring finely blended okra into an aluminum block resulted in the least crack in the dried sheet with the rectangular shape remaining intact. After the forming method is decided on a study was conducted on the temperature to bake okra at 3 levels namely 70 80 and 90 C.It was found that baking okra at 80 C for 4.5 hours was suitable the baking and crispy okra sheets ended up with the lightness(L*) of 49.75 the green (a*) was-2.53 and yellowness (b*) of 23.71. The moisture content was at 5.07 % water activity content was 0.27 The hardness was 5.01 N and the crispness was 4.67. The results of chemical analysis showed that the carbohydrate content was 76.34% crude fibers was 10.72% ash content was 8.24% moisture content was 4.24% and fat content was 0.46%. From the study on the bacteriological quality it was found that the crispy okra sheet products can be stored at room temperature for 28 days.

Studies on the use of okara to replace wheat flour in stoopwafel were done forto select appropriate amount of okara analysis nutritional facts and sensory evaluation. The stoopwafel basic recipe of magda (2559) was applied by using okara replaced wheat flour. The replacement percentages were 30 40 and 50 of the weight of wheat flour. The experiment is planned by Randomized Complete Block Design ( RCBD) . Then to evaluate the sensory quality in appearance color odor taste texture and overall preference with 9- point hedonic scale. The panelists were 60 lecturers and students from Home Economics Technology Rajamangala University of Technology PhraNakorn. Sensory evaluation showed that the okarastoopwafel prepared from 30 percent okara obtained the highest overall acceptance score from the panelistson all sensory attributes exceptedtesteattributes which there was no significant difference in three amounts of okara. The nutritional facts found thatfat moisture total energy and energy from fatwere slightly increased but protein and carbohydrate were decreased which compared to control stroopwafel ( 100 percent wheat flour) . In addition to 96 percent of consumer acceptedthe okarastoopwafel

The objective for this speciat is to leam how to make Tunglanna for decoration using Thai lacng techniques and study the con ntment of the target group. The production team has studied and researched thedata and then designed a drft about 3 Types of Tunglanna for a 7 porson speciaialist questionnaire. Then they will data to make a Tunglanna using Thai lacing techniques. Then they will have questionnaire with a target group of about 50 people so the analysis result wills ineude frequency percentage and average statistics. The conclusion: 1. Two procedures to make Tunglanna for decoration using Thai lacing techniques is chosen based on perfect shape proportion pattern and usefulness according to the specialist questionnaire. 2. The outcome of the target group questionnaire concludes: For making Tunglanna for decoration. Using Thai lacing techniques; the material is perfect but unfamiliar with an average of 4.64 the conclusion about usefulness implies. It is useful decorate a lot of different places. With an average of 4.50
