This research had the objectives to 1) study of the achievement in electronic document system for using in Rajamangala University of Technology Phra Nakhon 2) study the factors what they affect to satisfaction for electronic document system in Rajamangala University of technology Phra Nakhon 3) suggestion an improvement plan for these achievement system to develop and improve the relevant systems. The official workers in Rajamangala University of Technology Phra Nakhon were concerned in electric document system as 238 persons. The analytical data were Frequency Percentage Mean Standard Deviation t-test analysis Reliability of questionaires and One Way Analysis of Variance. The results shown as the satisfactions level in efficiency system Information system quality control system and management system were very good. The comparison of 2 samples groups by t-test at 95% confidence as the group who need the hard copy documents and useless documents with t-test at. The results were not different in the efficiency level information technology system and data management. The results more than 2 sample groups were analyzed by ANOVA at 95 % confidence. The result showed the satisfaction in the present position working of the samples as the instructors document official or relevant official and the other official was not different whereas the satisfaction in information technology was different. In addition the satisfaction of electronic document system was not different for the official in general education and management duty.

The purpose of this research is to study the heavy metal removal from wastewater from laboratory by using adsorption process with firebricks. Waste water was collected among three courses of laboratory such as analytical chemistry principle chemistry and chemistry for engineers. The optimized absorption efficiencies of multi-elements with stirring time volume ratio and temperature were 2 hours 10 g/100 mL and room temperature respectively. It was found that absorption efficiencies of lead (Pb) copper (Cu) zinc (Zn) chromium (Cr) were 65.1 54.8 63.4% and ND respectively.

This paper presents the design of automatic watering system using sun tracking as an energy source .The objective is to design the automatic watering system for fruits grown in both areas without electricity. The solar panel can be moved along the direction of the sun cover an altitude - azimuth dual axis as an energy source of the system. The 20 longan trees are used in the experiment. The DC motors and the solar panel is controlled and rotated by the microcontroller to the position of the maximum light intensity. The watering system section will use a technique to measure the soil moisture sensors ECHO2-20 with real time PC based monitor system by Visual Basic Studio. As for the experiment results it was found that the energy stored by the developed solar tracker increased to 17.72 percent in comparison to a solar panel fixed installation. The watering appropriate soil moisture content is 12 percent and stops at 25 percent resulting for the garden moderators to save time and labor.

The objective of this research is to find out the factors that affect academic achievements in the subjects which are fulfilled by using e-Learning in RMUTP by using questionnaire. The questionnaire is separated into 2 parts the first part is to find out the satisfaction level of each factor and the second part is to find out the effective level of each factor. After the researcher analyzed the data of tested questionnaire of 169 samples students by using Simple Sampling method from 294 students who study in the subjects which are fulfilled by using e-Learning the information were as follows: 1. The satisfaction level of factors is between normal And high the mean of satisfaction level of computer and internet infrastructure factor is normal ( x = 2.81) the mean of satisfaction level of supporting e-Learning system factor is normal ( x = 3.27) the mean of satisfaction level of the supporting personal factor is high ( x = 3.50) the mean of satisfaction level of e-Learning benefit is high ( x = 4.11). 2. The mean of effective level of computer and internet infrastructure factor is very high ( x =4.29) and the mean of effective level of supporting e-Learning system factor is normal ( x =2.98) In concluding to above information the computer and internet infrastructure factor is the factors that affect academic achievements in the subjects which are fulfilled by using e-Learning in RMUTP.

The purposes of this research are 1) to desired level of services University of Technology Phra Nakhon Library Using LibQUAL+TM 2) to evaluate the quality of services University of Technology Phra Nakhon Library Using LibQUAL+TM 3) to investigate the respondent’s suggestions for improving the service quality of Rajamangala University of Technology Phra Nakhon Library. This research survey by questionnaire topics showed that minimum-acceptable service level desire level of service and Perceived level of service. Questionnaires were collected 390 users from 191 undergraduate students 73 graduate students and 121 teachers in University of Technology Phra Nakhon. Then data were analyzed by SPSS for Windows for percentage mean and standard deviation The results revealed as follows; 1. The opinion of user about the services of the library it was found that the minimum acceptable level and the perceived level of services were at a moderate level while the desired level of services were at a high level. 2. On basic of the services quality it was found that mean of the perceived services was in zone of tolerance. The adequacy gap was positive. It meant that the services quality was acceptable. However that was not precisely the respondent’s expectation. The superiority gap was negative; it meant that quality of services did not equal the level of the respondent’s expectation. 3. Their suggestions were 1) Affect of service; including there were no enough library staff 2) Information control; including there were the books whose contents match the subjects offered is minimal not enough demand 3) Library as place; including there were restrictive library. Should provide enough space for the number of active users .
