Automatic watering system using solar PV tracking
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.

This research examined the green packaging development from banana fiber for instant food products.The purposes wrer to construct approve and develop the sketch design; to develop banana fiber package prototypes that protect food products inside in order to eliminate packaging environment problems; and to save energy in package processing in the next decade.It was found that as for packaging design for instant banana food products such as stand-up pouchpaper box paper cupand zip lock paper bag the satisfaction of every factor was at a good level (4.12) and every packaging pattem conformed to the identity design in structural and graphical packaging As a result of studying structural packaging factorsthey were at an excellent satisfaction level in every packaging pattern including aesthetic and elegant packages(4.63) identity packages(4.56) and souvenir packages(4.53). The satisfaction for graphical packaging factors was at an excellent satisfaction level such as identity brand letters(4.65) and easier to recognize as follow.
การเปรียบเทียบความสามารถการแยกแยะเนื้อหาตามระดับความรู้ผู้เรียนของครูที่เรียนรู้ด้วยสื่อ CAI กับการเข้ารับการฝึกอบรมสำหรับการสอนปฏิบัติคอมพิวเตอร์
There are three main purposes of this research. The first is to compare teachers ability in classifying content by students knowledge level before and after learning. The second is to study difference of pretest and posttest score according to students level. The third is to compare ability and determine efficiency in classifying content by duration of teaching experiences. Samples in this study were 30 teachers from Rajamangala University of Technology who leamed through CAI media (15 teachers) and who attended computer training course (15 teachers). The questionnaire was used to measure their ability in classifying content by students knowledge level. Results of the study can be concluded as follows: 1. Teachers ability in classifying content before and after leaming differed significantly at the level of 0.05. Howeverability in classifying content after leaming did not show significant statistical difference. 2. The difference in pretest and posttest scores showed that leaming with CAI could increase level of teachers ability in classifying more than attending training courses. 3. Teachers with different duration of teaching experience showed significant different ability in classifying content by students knowledge level at the level of 0.05. 4. Teachers with more than 7 years of teaching experiences showed the highest efficiency in classifying content.
The Development of Integrated Information System for University’s Administrators
The objectives of this research were to study the context of an information system for University’s Administrators of Ubon Ratchathani Rajabhat University to develop an integrated information system for University’s Administrators and to evaluate the developed system. The sample of the study included 24 administrator members and 7 officials at the Office of Ubon Ratchathani Rajabhat University. The research instruments were sets of interviews and questionnaires. Data were analyzed by content analysis mean and standard deviation. The study revealed that the information technology has been used in the department of Ubon Ratchathani Rajabhat University but the development is independent are there is a problem in report retrieval for university administrators. This study has developed an integrated system of information for university administrators by creating a data warehouse and establishing a connection between the data warehouse for each database. Data are stored in the data warehouse through data filtering of each daily segment in order to create a report for information which is accurate and running on network. The research results revealed that integrated information system for university administrators allows users to run a report according to the desired information quickly and easily. The evaluation of satisfaction and acception is at a high level a value of average is 4.40 and standard division is 0.55.

Product Development of Lotus Seeds for Health Food Industry aimed to develop 6 kinds of Processing food recipes and process which consisted of Instant lotus seed Lotus seed butter Lotus seed tablet Lotus seed Croquettes Lotus seed Cream and Lotus seed milk . The result process : time of boiled for lotus seed 20 minutes and Ratio of lotus seed and water type wet mill 2:1 and dry by tray dryer at temperature 70 °C time 6 hours. Instant Lotus seed was yellow light color and was Peak viscosity 113.675.51 RVU and Setback 39.66±±27.74 RVU. The Proximate analysis was found Moisture Protein Crude fiber Crude fat Ash and Carbohydrate were 5.06 16.47 3.26 0.72 35.48 และ 38.90 respectively. Lotus seed tablet was developed by ratio of Instant lotus seed : milk powder were 40:60 and using cocoa powder 9 %. Lotus seed tablet was brown color and moisture content 4.7% . The ingredient of Lotue seed paste were dry lotus seed : sugar powder 42:34 and using Carrageenan 1 % . Lotus seed Croquettes developed by ratio of Instant lotus seed : potato paste were 50:50 . Consumer test 52 % buyer. Lotus seed Cream using boiled lotus seed 20 % by weight and Lotus seed Cream no egg yolk it food for health. Lotus seed milk were Lotus seed 80% and pectin 0.5 %.
