Thestudy found that the highest score of sensory evaluation results from the Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour was the formulation number 2. The highest average ofappearance color smell taste texture and over all of the participants’ satisfaction were8.52 8.48 8.52 8.60 8.54 and 8.60 respectively. The result of Duncan’s New Multiple RangeTest DMRT showed differences with statistical significance at the 0.05 level (p≤0.05) in all 3formula. The highest score of sensory evaluation results from the Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Lotus Stamen was the formulation number 2 as well.The highest average of appearance color smell taste texture and over all of theparticipants’ satisfaction were 8.46 8.52 8.48 8.56 8.62 and 8.68 respectively. The result ofDuncan’s New Multiple Range Test DMRT showed differences with statistical significance at the0.05 level (p≤0.05) in all 3 formulations. In addition the nutrition fact test result in Thong Ek(Gold Foil-Decoration) from Lotus Seed Flour and Thong Ek (Gold Foil-Decoration) from LotusSeed Flour and Lotus Stamen - 100 g. in dry weight found that the amount of energy and fatdecreased. In contrary the amount of protein fiber and carbon increased. When analyzed bythe FRAP (umoles TE) and DPPH (mg AA) the antioxidant and Polyphenol (mg eq GA) in theThong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Lotus Stamen increased withstatistical significance at the 0.05 level (p≤0.05). Finally the detection of microorganisms inThong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Thong Ek (Gold Foil-Decoration)from Lotus Seed Flour and Lotus Stamen test result found the E.Coli less than 3 and noneSamonella SPP.

The purposes of this research were 1) to develop the model of group process Learning. 2) to compare the learning achievement between before and after learning from the group process Learning 3) to study the satisfaction of students of group process Learning in Thai for Presentation Course of the Students at Rajamangala University of Technology Pha Nakhon. This is an experimental research. The sample is 30 students in 1st year undergraduate in tourism major by purposive sampling who studied Thai for Presentation Course in the first semester (2019) at faculty of Liberal Arts Rajamangala University of Technology Pha Nakhon. The research instruments used in the experiment were 4 sets of group process learning management plan 1 set of achievement test used before and after learning and 1 set of student satisfaction questionnaire for group process Learning. The results were as follows : 1. The development of The group process learning using 4 sets which included small group process learning brainstorming group process learning discussion group process learning and the presenting group process learning was developed and applied in teaching and learning Thai for presentation course After the application the program was evaluated and it was found that the Index of Item Objective Congruence (IOC) of the evaluation of the quality of the group process management learning reached at 0.67. The Index of Item Objective Congruence (IOC) of achievement test reached at 1.00. And the Index of Item Objective Congruence (IOC) of the satisfaction reached at 1.00.

The purpose of this research was to: 1) use Multimedia Development to instruct Secondary 1 students learning Basic Sewing in Home Economics subject 2) compare academic achievement of students taught with the multimedia instruction and students taught with the conventional method and 3) study student satisfaction of the Multimedia Development technique Basic Sewing in Home Economics subject. A sample of 60 secondary 1 students attending Sinakharinwirot University Prasanmit Demonstration School was chosen using Cluster Random Sampling and were classified into 2 groups of 30 students; the first being the experimental group instructed with the Multimedia Development technique and the second being the control group instructed with conventional methods. The instruments of this research include lesson plans multimedia an evaluation form to track the multimedia efficiency a practice evaluation form and a questionnaire surveying student satisfaction. The statistics used for the data analysis were percentages mean standard deviation and a t-test. The results were as follows: 1) using Multimedia Development to instruct Secondary 1 students learning Basic Sewing in Home Economics subject achieved the efficiency of 82.14/80.06 2) the students taught with the multimedia technique have greater after learning achievement than those taught with the conventional method; statistical significance was at the .05 level and 3) the student satisfaction of the Multimedia Development technique Basic Sewing in Home Economics subject in high level is (x̅ = 4.42S.D. = 0.54)

The objective of this study were 1) to develop the gas detector unit for installation on Drone and 2) to test the operational sensitivity of the developed device. The development steps included designing complying the electrical circuit testing the electrical system and online connecting system. Besides the operational sensitivity of the developed device was tested comparing the Gas Alert Micro 5 IR the reference gas detector device both in the laboratory and the field site. The results showed that the developed gas detector could detect carbon dioxide carbon monoxide and methane and displayed the results via Line notification every minute. Additionally carbon dioxide detection by MG-811 sensor gave the results similar to the reference device by 95 percent of significant level with the average amount of detected carbon dioxide in the laboratory and the field site were 700-915 ppm and 138-399 ppm respectively. However the measured results of carbon monoxide and methane from the develop device were relatively different to the reference device. Further study on carbon monoxide sensor and methane sensor calibration are recommended.

The research was to develop environmental packaging from composite materials hyacinth fiber rice husk and coconut fiber for temperature preservation to replace the use of foam packaging that cannot be degraded naturally. In the composite materials water hyacinth fiber rice husk and coconut fiber at the ratios 7: 1: 2 1 : 1 : 2 and 1: 1: 1 were extruded by heat using isocyanate glue as a solder and testing the physical and biological properties of composite materials as fiberboard. For testing of temperature preservation of the bio packaging heat transfer test to obtain the bio-packaging for the environment the composite materials of fiber water hyacinth rice husk and coconut fiber at the ratio of 7 : 1 : 2 was the most appropriate type. Since it had a density of 0.7 grams per cubic centimeter strength of 26.76 MPa moisture content of 3.8 percent ages and swelling of 26.63 percent ages. In dry condition at room temperature it could store heat for 2 hours and could retain the cold temperature as shown for the temperatures rising from 4 to 30.7 degree Celsius within 2 hours. This research therefore presents a new alternative method of natural fiber composite materials application for temperature preservation in order to reduce the use of foam containers and increase cost value to natural bio waste materials.
