As a result teachers and students have to communicate online. As a result students who deal with the registration documents follow up with their advisors about the status of the registration documents. head of department and branch coordinator through online channels such as Line Messenger email etc. which resulted in advisors head of department and branch coordinator There is an increasing workload. from the problems mentioned above Therefore the researcher proposes a research project on the development of a registration document tracking system for students of the Faculty of Business Administration. Rajamangala University of Technology Phra Nakhon In order to reduce the workload of teachers and staff in answering questions about the status of registration documents for students The results of the research showed that the registration document tracking system can help increase the efficiency of teachers and staff. It also gives students the convenience of tracking the status of documents submitted for registration and processing.

This research is to develop an internal inventory management system. Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon To evaluate the results of the use of information systems for managing supplies within the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon The data was collected between October 2019 and September 2020 as a survey research using questionnaire tools. It consists of 4 parts: 1) general information of the respondents which is demographic characteristics 2) current condition and needs of the parcel management system. Faculty of Liberal Arts University of Technology Rajamangala University of Technology Phra Nakhon 3) The efficiency of the procurement management system Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon and 4) satisfaction of the procurement management system. Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon With the sample groups in this research are Support personnel Under the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon comprised of 21 persons. The data analysis used descriptive statistics for demographic characteristics. The study found that Current conditions and procurement development guidelines Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon Overall and from the bottom to the bottom including parcel payment Parcel picking Accounting for parcel control And material storage respectively efficiency of the parcel management system Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon Overall and each side Very level When sorting the efficiency of the parcel management system in descending order namely the information security aspect of the system. Aspects to meet the needs of system users Functional aspects according to the system function And the ease of use of the respective system and the users satisfaction with the parcel management system.

The objective of this research was to study of rotary drying of high-moisture long pepper by using a combined hot air and infrared radiation. The experiment was carried out at the drying temperatures of 80 90 and 100 °C infrared power level of 500 W hot air velocity of 2.5 m/s and rotary revolution of 3 6 and 9 rpm. In this study two patterns were examined by the different drying conditions namely 1) hot air drying and 2) combined hot air and infrared radiation drying. The effects of above drying parameters on the change in moisture content of long pepper and specific energy consumption (SEC) of the drying system were investigated. The results showed that the combined hot air and infrared radiation drying was shorter drying time than hot air drying. The lowest total SEC during drying process of 26.77 MJ/kg water when the drying temperatures of 80 °C infrared power level of 500 W hot air velocity of 2.5 m/s and rotary revolution of 3 rpm were used.

Vegetable Growing System has an absolute requirement of nutrients and minerals. The microbial application can facilitate in addressing limited access to chemical fertilizer concerns. Moreover the photosynthetic microorganism community can contribute together in nutrient availability for plant growth. This research aims to develop an automatic hydro-organic vegetable growing system. Moreover the analytical of photosynthetic microorganism growth rate in fermented juice was also observed within three months in terms of temperature pH electroconductivity total dissolved solids mixed liquor suspended solids and phosphorus. The efficiencies of an automatic hydro-organic vegetable growing system were also monitored along an experimental period (45 days of operation optimization). The vegetable growth rate was observed in terms of leaf length leaf width and root length. These experimental results showed that the phototrophic growth of photosynthetic microorganisms should the main bacterial activity at daytime operation and vegetables could grow by using fermented juice. The photosynthetic microorganism concentration and nutrients concentration in fermented juice was significant to promote the productivity of vegetable growing which the photosynthetic biomass is rich in proteins and vitamins. Besides this system can be easily applied and also very cost-effective for agricultural practice and frequent maintenance every experimental run was necessary.
