This study was experimental study that had the propose to investigate the possibility of using sludge from wastewater treatment of milk production in case study of Friesland Campina Fresh (Thailand) Co Ltd. This study to investigate suitable ratio in making briquette between sludge and banana peel in ratio 95 : 5 75 : 25 50 : 50 25 : 75 and 5 : 95 by weights and analysis of compressed char were Moisture content Ash content Volatile matters Fixed carbon and Calorific value. The result of this study we found that sludge mixed with banana peel at the ratio of 25 : 75 had Moisture content 9.7 percent Ash content 15.8 percent Volatile matters 61.8 percent Fixed carbon 9.7 percent and Colorific mean 4195 kcal per kg. It can also be used briquette fuel substitutes of firewood in order to conserve the forest resources.

This research is to study the production of fuel briquettes from the Nipa palm and Fat dregs in the ratio 1:0 1:0.1 and 1:0.3 kg respectively. We performed a study of the properties of the fuel briquette produced and also study the heating value moisture content ash volatile matter and fixed carbon. The results showed that the heating value of the fuel briquette is the most fuel briquette sclera ratio of fat and the residue was 1:0.3.The heating value of 5370 calories per gram. Followed by fuel briquette ratio 1:0.1 and 1:0 with heating value of 5300 and 5280 calories per gram respectively. The results also showed that increasing the amount of fat dregs ingredients make heating value of fuel briquettes increase as well. Also when the fuel briquette production tested by igniting the fuel briquette with no mixing of Fat dregs can ignite flammable odorless and smokeless. Fuel briquettes that are mixed in a ratio of 1:0.1 and 1:0.3 of fat can ignite flammable. The smell of burning grease and smoke residue to consider using a combination of fat dregs in fuel briquette for reduce the amount of waste that could affect the environment.

The aim of this research is produced the media of history of local craft center in Napho district Buriram province and also the production processes of Mud Mee silk fabric. The process in weaving the silk Mud Mee is meticulously performed in every step beginning from the processes as follows; selecting of silk yarn degumming dyeing Thok Kwuak Khon Mee put the yarn on Hong Mud Mee Bleaching untied silk yarn roll the untied silk yarn onto the warping reel and reel the yarn from the spool rack to the spinning wheel. From the data which obtained from the research to produce media such as leaflets poster and VDO. This media are devised into four topics include Thai and English language as follows; (1) the local craft center in Na Pho district Buriram province Thailand (2) preparation and dyeing of silk yarn for Mad Mee silk fabric (3) Mud Mee weaving process: weaving pattern design and colour of Napho Buriram silk fabric (4) innovative development of clothing bag home textile from Mud Mee silk fabric. The benefits of produced media to be as a local learning center and cultural tourism place for doing study field trip researching. The media are there to guide the history of local craft center Mud Mee silk fabric production and Mud Mee silk product for those who are interested and transferring knowledge by the media to student and also some group learning.

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 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.
