This research is the development of an energy - saving water planting kit. The objective is to develop a prototype of an energy - saving water planting kit by applying solar energy as an energy source that is controlled by the Arduino board through a blynk application and study the efficiency of the water culture planting kit. By comparing electricity usage rates between solar energy and electric power from the household. In this study there were 4 experimental sets. The experiment was water cultivation without installation 2 experimental sets and 2 experimental sets were installed using green salad vegetables. In research the 45 days growth period consisted of leaf length and width root length number of leaves and height. There is also a comparison of the efficiency of AB fertilizer and soy milk hormones to reduce chemical usage. The research has shown that the use of the soybean milk hormone provided a high growth rate of Lactuce sativaVar. Longifolla than AB fertilizer. There are many nutrients but only in small amounts. When used as a nutrient for plant growth needs to be changed daily. Considering the economic value using AB fertilizer as a nutrient will be worth more than soy milk hormones. For the installation of the instruction set and the LED lamp was suitable for Lactuce sativaVar. Longifolla growing than not installing the instruction set and the LED lamp. These can save electricity cost of 85 baht per month.

Nanomaterials are widely used in many applications such as medicine cosmetic industry and other. When the size of the particle is reduced the number of atoms on the surface and the ratio between surface area to volume of the material increase result in the enhancement of the material’s physical magnetic and optical properties. There are many methods to synthesize the nanoparticle such as grinding chemical reaction electrochemical method and laser ablation. In this research laser ablation was chosen to synthesize the metal nanoparticles because this method is quick and convenient and does not produce hazardous waste. The results show that the laser with 6V electric potential could synthesize the metal nanoparticles with the smallest size. The metal nanoparticles with larger size were obtained when higher electrical potential of 8V and 10V were used. In conclusion the electric potential of the laser affects the size of the metal nanoparticle obtained from laser ablation.

This project presents the website T.K. Beach Resort Koh Mak. The objective is for the residents of T.K. Beach Resort Koh Mak Resort. The system has been developed in the form of a web application. Using PHP and Xampp to create database for the T.K. Beach Resort Koh Mak website the work efficiency to facilitate the work of the system administrators And to facilitate the users of the system From the evaluation of the satisfaction of using the website T.K. Beach Resort Koh Mak. The evaluation of the satisfaction with the use of the questionnaire tool (Questionnaire) collected the opinions of 20 users when considered in each aspect found that the aspect that has the highest level of satisfaction first is the system design. Received a total average of 4.76 followed by the satisfaction of the users of the system Achieving a total average value of 4.66 and system performance Obtained a total average of 4.62 respectively which can summarize the overall average of all 3 sides. The average value is 4.68 which is at a level of users very satisfied.

In order to maintain food and materials including drying products at the original dried condition silica gel can be one choice for absorbing moisture. Most silica gel is packed in an Parcel made from plastic which is difficult to naturally degrade thus causing environmental problems. This research therefore have developed packaging material from agricultural waste corn husks for absorbing moisture from food rice. From the study it was found that the corn husk paper had characteristic of smooth paper surface. When making it into a corn fiber Parcel its maximum moisture absorption from saturated humidity was 9.22±0.92% and it could absorb the moisture from the rice stored at room temperature when compared to the plastic sachet at 8.26±0.50% and 9.30±0.08% respectively. When coated with kaffir lime oil extract the corn husk Parcel had the capability in anti-fungus commonly habituated in corn husks up the concentration of 15000 ppm. It could naturally be degraded within 12 days. Therefore with these advantageous qualification the natural Parcel made of corn husk paper harboring silica is for moisture absorption as sustainable and environmental conservation material.

Scholarship Website Project Faculty of Science and Technology Is a website developed to meet the needs of personnel and students. Faculty of Science and Technology to be informed of scholarship news of the university. The website will have a system that is generous to distribute information scholarships. Which will enable personnel to increase scholarship information and will provide students with information documents of the Faculty of Science and Technology scholarships. Quickly and facilitates access to news stories about scholarships at Rajamangala University of Technology Phra Nakhon The results of the scholarship website development Faculty of Science and Technology Which the website can be used within the scope specified by the manufacturer and the users of the website have overall satisfaction at a good level. With an average of 3.94. When considering each aspect it was found that Website design performance and attitude. The satisfaction is at a high level. With an average of 3.91 4.01 and 3.95 respectively. In conclusion the scholarship website Faculty of Science and Technology can be used effectively.
