This research was aimed to study the participation behaviors in the electrical energy saving the factors affected to the participation behaviors and the promotion of the participation behaviors in electrical energy saving of the undergraduate students of the Faculty of Science and Technology Rajamangala University of Technology Phra NaKhon. The participants of 150 students from the Faculty of Science and Technology was also performed based on systematic sampling. The questionnaire was used. The statistical evaluation was also analyzed based on the percentage mean and standard deviation. A 85% of participants is male a range of age to be 19-20 years old (62.7%) second academic years by about 37.3% and a 65.3% of participants has been studying in the major of computer science. Knowledge levels in the electrical energy saving of the most participants are high (13.33%) moderate (62%) and low level (24.67%). The four participation behaviors in the electrical energy saving were analyzed including electrical lighting system air conditioner and ventilator system office electrical system and electrical equipment maintenances resulting in very high level with the average mean of 4.25 and standard deviation of .547. First the participation behavior in the electrical equipment maintenance was very high level with 4.31 and S.D.=.870. Second the participation behavior in the office electrical system was to be 4.27 with S.D.=.828. Third the participation behavior in the air conditioner and ventilator system was to be 4.21 with S.D.=.549. Finally the participation behavior in the electrical lighting system was very slow level with 4.21 and S.D.=.672. By comparing the participation behaviors in the electrical energy saving with the different of academic major of students the participation behaviors in the electrical energy saving did not significant different.

This research studies dyeing with Thai herbs for UV protection properties in textile products applications and aimed to: study procedures and techniques for this; investigate the use of herbal plant for UV protection; study UV protection properties in fabrics dyed with Thai herbs that can protect against UV rays. The process involved dyeing from natural surplus materials (militia kityana leaves lemongrass leaves and areca palm seeds) extracting the dyes for use in silk dyeing with a mordant to increase the affinity of the dye and fiber then rating the percentage of UV light blocked. Finally the fabric was used to design clothes as a prototype for five Muslim outfits. The research team chose dyed silk fabric with the percentage of UV light blocked are 95.67 – 96.24 which is in good to excellent protection level. Five outfits were designed for this study: 1) Silk dyeing with dyes extracted from the lemongrass leaves – using the first method of fabric dyeing with clear muddy water 1% as mordant 2) Silk dyeing with dyes extracted from lemongrass leaves – using the fourth method of fabric dyeing with the fabric fermented for 30 minutes in mud before dyeing 3) Silk dyed with dyes extracted from areca palm seeds – using the first method of fabric dyeing with 3% tamarind water as mordant 4) Silk dyed with dyes extracted from areca palm seeds – using the fourth method of fabric dyeing with the fabric fermented for 30 minutes in mud before dyeing and 5) Silk dyed with natural dyes extracted from militia kityana leaves – using the first method of fabric dyeing with 1% tamarind water as mordant.

The objectives of the research ancient woven design of Laocrung Baan Kokemor Uthai Thani province to study and collect ancient woven designs of Laocrung to preserve knowledge about woven design and to conserve the ancient woven design of Laocrung Baan Kokemor in view of their indigenous knowledge about weaving particularly identity in color and weaving techniques which show off the charming customs traditions cultures and belief reflected in Laocrung. This research aimed to study phasin of more fabrics than 50 years and present pattern by pattern comparisons to effect conservation and maintain database of Laocrung Baan Kokemor. The study found that Phasin ancient woven design of laocrung Baan Kokemor is unique in three identities: 1) the Nature of Phasin can be divided into four types--sinmeeta sinmeenoi whole sin and sipsiw pattern; 2) the color scheme is always in red lac sin; and 3) the color marking is in the mudmee pattern called “tamtakor”. Phasin weave patterns were found mudmee pattern such as khor luang-noi luang-yai ta-pho hongse nark khor-rakhung mee-luangnoi khun-chung mee-tapao nak-kad klong mee-tayai nak song hua lao dan noi nok khor kai klong kee kab thong punchung sumroaj huatud sumroaj hua laem lai khorkhue khorging and tapaokaew; jog patterns such as a-ae khonglueng hongse luk kruengplong (striped mini employed in all) tuay khorkumsorn khorkumlek korkhuenoi khorbuay dokkaew khorkhueyai khunrom and jog ueng-peek-kai; and khid patterns such as khidsiw and mae rod.

A study on developing textile products from fiber lemongrass has been carried out aimed at processing yarn from lemongrass fiber developing textile fabrics such as clothing hats and shoes and teaching product design and technology to a community. Lemongrass leaves were processed with chemicals to produce a fiber lemongrass then spun to 100% lemongrass yarn with large unsmooth surfaces the used to produce handbag hats and shoes. However for garment fabrics the researchers developed the lemongrass yarn for weaving by mixing cotton in a 60:40 ratio to produce hand-woven cloth. Using hand-woven folk wisdom the Takfa community in Nakhon Sawan produced natural dyes from Bengal Almond leaves a performed surface finishing for a smoother touch. After weaving lemongrass fiber cloth gives off a lemongrass odor but this fades gradually. The physical properties of lemongrass fiber cloth are then tested for strength resistance and abrasion. Processing lemongrass cloth fiber to textile products enables us to produce various products such as clothes bags and hats. In passing technology to the community the residents recognized the advantages and benefits of using the fabric. Further research should investigate mixing lemongrass fibers with other natural fibers improved fiber durability luster of the fiber to increase fiber value or using lemongrass fiber for household products.

This research deals with paper production from lemongrass and producing a model product. The lemongrass was boiled in sodium hydroxide solution 400 grams per litre of water at 80 – 100 degrees Celsius for 3 hours. The separated fibre was then bleached with chlorine solution 20% per lemongrass fibre 1 kilogram per water 1 litre. Finally paper pulp was scooped for paper formation and lemongrass fibre paper was soaked with flame retardant 10% for 10 minutes at room temperatures. The physical properties of the paper were tested – mass per unit length longitudinal and cross section burn tearing strength absorption and heat resistance. This research was conducted by cutting lemongrass leaves to a uniform length boiling them to separate the fibres for toughness with high strength: the longer the lemongrass leaves the greater the strength. The dirt mixed was removed by boiling the separated fibre. To achieve quality standards the products should be designed analyzed evaluated and modeling. Sampling group evaluation were used to help develop lemongrass fibre products for commercial production using natural resource with maximum cost benefit and technology transfer to the target group. The result of this research was to develop and process home furnishing accessories and souvenirs such as lamps photo frames paper boxes tissue box and souvenirs. The procedure for this research was to analyze the satisfaction level of trainees from Sridonpai Dumnoen Saduak District Ratchaburi community and interested groups amd found that the service provided by officer trainer service processing and accommodation were on average of high level (X = 4.45 4.35 4.22 and 4.42 ordering)
