This study explored the dietary effect on manure characteristics and potential of biogas production from the manure of dairy cows feeding with pineapple peel as a roughage source. Three mid-lactation primiparous crossbred Holstein dairy cows which had an average body weight of 443.5±10.6 kg and average milk production of 9.6±0.3 kg/d were assigned with three different diet types including T1 T2 and T3. T1 was a control diet which consisted of a mixture of dry Pangola grass and commercial pellet (CL). Moreover T2 was a mixture of dry Pangola grass pineapple peel and CL while T3 was a mixture of pineapple peel and CL. Dairy cow manure was collected on the day 10th after feeding and anaerobic digestion of the dairy cow manure was operated with an HRT of 30 days. Results showed that all diet types gave similar manure characteristics of high organic matter and nitrogen. Average concentrations of TS and COD ranged from 82.59 to 85.78 g/L and 85.47 to 91.47 g/L respectively whereas TAN ranged from 1.54 to 1.67 g/L. However a higher pH of 7.50 was found for the manure of dairy cow fed with T1 while a lower pH of 6.50 was obtained with T3. Besides the highest methane yield of 0.20 m3 CH4/kg VSadded was obtained when using the manure of dairy cow fed with T1 as a substrate followed by T2 and T3 which found at 0.14 and 0.11 m3 CH4/kg VSadded respectively. This indicated the efficient potential of biogas production from the manure of dairy cows fed with pineapple peel which will improve sustainable utilization of agricultural wastes and waste produced from dairy cow farm in the future.

This research objective is to improve the overall equipment effectiveness of the water filtration systems in the case study of the Water Treatment Plant which divides the water production into 4 production lines. The water filtration system has an electric actuator and gear is the main machine in the water filtration system. An electric actuator and gear have more machine breakdowns. That makes the water filtration system is the bottleneck of the water production process. This research study is divided into two steps: the first step is the presentation of the equation and the steps to measure the Overall Equipment Effectiveness of the water filtration system. The equation used data from the computer maintenance management system to analysis on mean time between failure data (MTBF) mean time to repair data (MTTR) and water production process data. The results can be improved the overall equipment effectiveness of the water filtration system increased to 0.11% 0.68% 0.44% and 2.44% respectively in each production process line. And increased Quantity of Filtration Water increased to 328500 m3/year 1168000 m3/year 1022000 m3/year and 3832500 m3/year respectively in each production process line. In this research used the pillar of focus improvement. By adding a protection system to prevent machine breakdown because of the most of the problems are found that the protection system malfunctions. This is the most problem in the 4th And then used engineering knowledge to improve water production and the success factor are required a human resources of all parties to cooperate brainstorm and analyze the causes of various losses in order to eliminate them.

The objectives of this study and product development of Thai Song Dam fabric womens bags were to study the cultural identity of the Thai Song Dam people to develop womens bags made from Thai Song Dam fabric and to study the satisfaction with the development of Thai Song Dam women bags products. The research instruments were an interview and a questionnaire for 80 women who were interested in Thai Song Dam fabric bags. The data were analyzed using a statistical package program such as frequency percentage mean and standard deviation. The results of the study on cultural identity of the Thai Song Dam people found that the dresses and souvenir products of the Thai Song Dam people have the most unique patterns to decorate the fabric which is embroidered with Piao flowers pattern. As for the development of bags made from Thai Song Dam fabric it was found that Thai Song Dam women’s bag are not produced. The researcher therefore studied by applying the patterns of womens bags that are popular today and applying the embroidered with Piao flowers patterns that are the identity of the Thai Song Dam people. As for the satisfaction towards the product development of Thai Song Dam womens bags it was found that overall product development satisfaction was at the highest level (x = 4.75 S.D. = 0.90). The overall satisfaction in sewing products was at the highest level (x = 4.64 S.D. = 0.39) and the overall bag product satisfaction was also at the highest level (x = 4.88 S.D. =0.32).

Promotion of handicrafts in the field of natural dyes in the country. Increase the potential of the community and use the strengths of the cultural community. way of life and wisdom by finding ways to develop textile products by using creative textile innovations based on local wisdom in sustainable community areas To add added value to products in the ECO PRODUCT and ZERO WASTE product groups from the aforementioned concept To conserve plant genetics that exist throughout the country. The researcher therefore studied the process of dyeing fabrics by natural methods. By taking natural ingredients that are locally available and transforming them into environmentally friendly home products. This research is to study the natural dyeing of cotton fabric from Kasalong core. have a purpose Study on the effect of dyeing and the use of adjunctive agents in natural dyeing from Kasalong kernels. To develop dyed fabric products from Kasalong core and to pass on the knowledge and technology of developing dyed fabric products from Kasalong core for the general public. The result of dyeing cotton with natural dyes from Kasalong core. Four types of adhesives were used at a concentration of 20 percent as tamarind juice lime juice lime juice ash water and to test the washing fastness and sunlight resistance with the AATCC standard. The results can be summarized as follows. 1. The results of the study found that from the extraction of color from Kasalong kernels and then filtered with cloth. The color water extracted from Kasalong essence is brown. and when left for 24 hours the water color is dark brown and in this research using hot dyeing methods. 2. The result of dyeing cotton with natural dyes from Kasalong core without mordant using was found to yellow-brown but after washing the color intensity on the fabric fades slightly. 3. The result of dyeing cotton with natural color from Kasalong core. It was found that after washing the color intensity on the fabric was moderately fading. 4. The color measurement L* a* b* found that when the dye was measured in the CIELab system L* = 26.81 a* = 33.33 b* = 45.69 dL = 0.36 and dE*ab = 0.85 water. The resulting color from Kasalong will be reddish yellow. 5. Make the research prototypes as 10 of bag products. 6. Conducting technology transfer by organizing workshops dyeing course and sewing durating of the workshop for students and the general public was 1 day. Most of the participants had the highest level of satisfaction in all questions.
