A Comparison Efficiency of Cafeteria Wastewater Treatment with EM Produced by Banana Watermelon and Guava Case Study : Rajamangala University of Technology Phra Nakhon Cafeteria ( North Bangkok Campus) has the objective to compare the efficiency of wastewater treatment by using the EM microbe for the Cafeteria that has no waste water treatment system. The treatment solution was leavening agent EM : Molasses : Fruits : Water in the ratio 1 : 1 : 2 : 20 liters (as an experimental group) and leavening agent EM : Molasses : Water in the ratio 1 : 2 : 20 liters (as a control group). respectively and mixed each solution set in wastewater treatment ratio of 1 : 1000 (EM 1 part : wastewater 1000 part) . In the experiment use the 10 liters of wastewater sampling and added the EM microbe solution every 3 days 10 ml per a day and daily for 3 weeks. Collecting the wastewater every 7 day. Parameters in this experiment are BOD COD SS Oil and Grease pH Color and Odor. The comparison showed that the EM made from watermelon can reduce the BOD and SS of wastewater is the best. And adapt the most of pH to pH 7. The EM make from guava can reduce the COD Oil and Grease is the best. The results were in the standards of sewage release of the building type B. In the 1st 2nd and 3rd week the BOD COD SS Oil and Grease and pH from the waste water treatment with EM microbe that make from Banana Watermelon and Guava ( as a Experimental group) and molasses (as a Control group) only are statistically different at the .05 level. By the way the Color and Odor of the waste water analysis before and after treatment with EM microbe 4 species still have yellow color and bad smell.

The experiment was in a type of 4 experimental wells with the size of width x length x height was equal to 0.5x1x 0.5 meters including the experimental well which had plants of Colocasiaesculenta (L.)Schott PandanusamaryllifoliusRoxb and Canna indica Linn and the rest was the control well without any plants. The time period of Alternating 5 days flooding and 2 days drying Soil. The parameter studied included BOD value suspended solids Total KjeldahlNitrogen Total Phosphorus pH and Oil and Grease. The research result found that the experimental well which had Colocasiaesculenta (L.)Schott PandanusamaryllifoliusRoxb and Canna indica Linn had the effectiveness in wastewater treatment higher than the control well without any plants. After treatment with the control well without any plants the experimental which had plants of Colocasiaesculenta (L.)Schott PandanusamaryllifoliusRoxb and Canna indicaLinn with the romoval percentage of BOD value at 22.66 69.93 63.48 and 76.37 respectively.Suspended Solids at 22.66 69.93 63.48 and 76.37 respectively.TotalKjeldahl Nitrogen at 26.41 68.67 64.21 and 72.99 respectively.Total Phosphorus at 52.26 81.6975.73and79.88respectively.pHat6.42 6.556.64and 6.88 respectively.Oil and Grease at 62.08 78.75 76.47 and 80.39respectively.

This independent study aimed to 1) study the level of the work satisfaction and the organization commitment of the employees in the Faculty of engineering Rajamangala University of technology Phra Nakhon; 2) study the relationship between the work satisfaction and the organization commitment of the employees in the Faculty of engineering Rajamangala University of technology Phra Nakhon The samples used in this study were 154 Staffs who worked at The Faculty of Engineering Rajamangala University of Technology Phra Nakhon. The study instrument was the questionnaire used to collect data. The results showed that 1) the level of the work satisfaction and the organization commitment of the employees was positively at a high level. 2) The relationship between the work satisfaction and the organization commitment of the employees was found to be significant at the .01 level.

This research intends to study the English language learning strategies of students in the faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon and to compare the learning strategies among gender three fields of study and English language achievement. The population group is 215 second-year Liberal Arts students in the second semester of the academic year 2016. The instrument was the Strategy Inventory for Language Learning (SILL) questionnaire. The obtained data were analyzed to find percentage mean and standard deviation. The study findings revealed that the overall use of English language learning strategies was at the medium level (=3.19). When considering each strategy the highly used learning strategy was compensation learning strategies (=3.46) and followed by affective learning strategies (=3.36) metacognitive strategies (=3.15) social strategies (=3.13) memory strategies (=3.03) and cognitive strategies (=3.01) respectively. The result also indicated that the learners’ fields of study and English language achievement significantly affected the overall learning strategies but gender did not show significant differences.

A Study of Factors Affecting Student’s Decision to Drop out School: A Case Study of Faculty of Industrial Textiles and Fashion Design Rajamangala University of Technology Phra Nakhon was an applied research. It was designed for analyzing the voice of customers in student studying management. The samples group was four department students in the Industrial Textiles and Fashion Design faculty as Garment Technology Textile Chemistry Technology Fashion and Design and Product design who retired during study and graduated in 2014 and 2015 academic year. The research results were used for improving the study efficiency and reducing the unexpected study. From the results shown the most problem was withdrawn registration especially in the first and the second year student. Garment technology department was the highest rate of retention after that Fashion and design Textile Chemistry Technology and Product design were respectively. The education satisfactions survey was found the moderate level for curriculum and lecturer as the mean 2.57 and 3.14 orderly. Additional the environmental satisfaction was low as 2.26 for the unexpected education students. In the other hands the graduated students had the greater satisfactions for the whole factors. The curriculum satisfied was good as 3.30 the lecturer was best as 3.67 and the environment was moderate as 2.95 correspondingly. From these results the Faculty of Industrial Textiles and Fashion Design were developed and pay attention in the subjects and lecturer in the first and second year education. The understanding of core study and the essential of each department was the significant factor for retaining and priding the student until they graduated in the Faculty of Industrial Textiles and Fashion Design.
