This research has been object to development weaving machine design weave dye and Hyacinth paper and Instruct technology give community District Bangsai Amphur Province Ayutthaya which get instruct technology 20 persons. Research result to invention make up weaving machine. Fiber from Water Hyacinth dye Yarh Pa Per from water Hyacinth and product about 11 products. Evaluation from the participants were female aged 35-55. They were workers and earned 500-1000 Baht per month. Before training they had little knowledge. The training contents were correct and up-to-date. The trainers were excellent. The material equipment and documents were the most appropriate. The Participants had good attitude and the designing and developing of water Hyacinth’s was the most appropriate.

This research has been object to development weaving machine Equipment for weft. Design weave and Instruct technology give community. By make up weaving machine be able to ten The construct equipment for weft to tightness be equal to weft. Design weave and weave to consist Plan choose thread Heddle to tie and Move treadle. Instruct technology give community District Bangsai Amphur Provice Ayutthaya Which get instruct technology Make up weaving machine and design weave. Research result to invention make up Hyacinth weaving machine. Functional be durable Convenient to use in community. The construct equipment t thread Which consist litter move thread Bench to roll and bench t copy Functional be successful. Because of compare weft not pass process for weft at construct will cause thread tightness unequal have impact When divide weft for insert warp Divide weft unequal and Cause weft have tightness Impact when divide weft for insert warp divide weft unequal and break every. Section weft at pass process move weft thread be on as tightness unequal and will cause warp be convenient and not break. Have an effect on weave be convenient and marquisette high-quality. Design that in quantity at equal when design get efficacious change treadle be able to begin new design new design by not design. Instruct technology give community and community get technology and be able to design weave get efficacious. Evaluation from construct invention Design weave and instruct technology cause to know. Possibility that take research give community general and production to commercial continually.

Nitrogen is an essential nutrient for plant growth. When the plants have been grown for a long-term effect to decreased nitrogen in soil and insufficiency of the plant growth. One biological method for increasing the nitrogen content in soil is utilize of free nitrogen-fixing bacteria Azotobacter. Therefore the objective of this research was to search natural material suitable for Azotobacter fixation. The 10 natural materials were observed physical structure and investigated the ability of natural materials for Azotobacter fixation. The results showed that water hyacinth and bagasse stalks were fixed the Azotobacter of 2.43x108 and 1.94 x108 CFU per gram of each natural material respectively. After that the selected fixed Azotobacter of water hyacinth and bagasse stalks were studied the growth of Brassica Chinensis. This experiment was designed to 4 treatments. The first treatment was mixed of water hyacinth stalks and the Azotobacter. Second treatment was mixed of bagasse stalks and the Azotobacter. The third treatment was the Azotobacter only. The last treatment was soil only. The results indicated that the average of plant growth include height leaf number root length fresh weight and dry weight of the mixed of water hyacinth stalks and the Azotobacter had significantly higher growth rates than other treatments. The total nitrogen was also increased 1.4 fold in the soil. All results suggest that the water hyacinth stalk is alternative for the fixation of the free nitrogen-fixing bacteria Azotobacter as induce nitrogen in the soil and plant growth promotion.

The objective of this research was to compare the effectiveness of water hyacinth and cootail for wastewater treatment by taking water sample from Klong Bangkhen-mai near King Mongkut’s University of Technology North Bangkok. The results showed that there was no diifference on water temperature changes in tanks between two plants. pH of water in coontail tanks was between pH 8.69 to pH 8.91 and pH of water in water hyacinth tanks was slightly increasing between pH 7.71 to pH 8.26. The more amount of coontail added the higher DO would be between 9.18 mg/L to 10.02 mg/L. Moreover COD of water was decreasing according to the amount of cootail addition and more effective than that in water hyacinth tank especially in 150 grams coontail tanks but TS in water hyacinth tanks was much more decreasing than that in coontail tanks. TS was between 21.73 mg/L to 25.91 mg/L. COD was between 45.30 mg/L to 48.34 mg/L.
