Due to the epidemic situation of Covid-19 has had a huge impact on the Thai economy and society. make a government agency Many private companies have to work from home. which the Faculty of Business Administration Rajamangala University of Technology Phra Nakhon is one organization that has a policy for teachers and students to teach online. 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.

The objectives of this study were to produce One Stop Service infographic and study the satisfaction of One Stop Service infographic of Rajamangala University of Technology Phra Nakhon (RMUTP). The data was corrected from 102 students. Data was analyzed by percentage average and standard deviation. The results showed as follows: the satisfaction of One Stop Service infographic of RMUTP was at high level (𝑥̅=3.95)

This research is to study the efficiency of treating wastewater from dyeing fabric by the ozonation process. By using rutile TiO2 coated plastic media to catalyze. Which uses O3 generators with a capacity of 2.62 - 3.10 g/hr. By studying the factors that affect the treatment efficiency of COD and color such as the pH of the water used in the treatment at pH 3 pH 7 and pH 11 the initial COD concentration of 100% 50% and 25% which have values in the range of 100 -320 mg/L. O3 exposure time 120 min. From the study it is found that the efficiency of reducing the impurities in wastewater by the ozonation process in the pH 11 state the COD concentration at 50% can reduce the COD. And the maximum color is at 33.3% and 90% from the 550 ADMI color intensity with a COD of 180 mg/L. For the study of the efficiency of reducing the impurities of wastewater by ozonation process together with 2 g. of TiO2/1 L. of wastewater in the condition of pH 11 concentration COD Beginning at 100% with the ability to reduce COD values And the maximum color is at 40% and 80% of the 270 ADMI color intensity with a COD of 190 mg/L. The amount of O3 suitable for treatment has an average value of 0.0374 g/min./10.5 L. of wastewater. The duration of O3 exposure in both processes has a similar approach to the efficiency of COD and color treatment when increasing the duration of O3 exposure.

Study on the amount of soybean powder for substitution of coconut milk powder. The purpose is to reduce fat from coconut milk and use soybean powder to replace the concentration of finished coconut milk. By studying the basic formula of coconut milk powder by selecting 3 formulas and taking the most scores formula Bake at 70 degrees Celsius for 7 hours humidity at 1%. The results of consumer acceptance study by measuring the quality of the appearance texture color smell By leading to being accepted by consumers Testing the quantity of soybean powder suitable for the product by measuring the quality of appearance texture color smell. To be acceptedby consumers Study on shelf life of soybean powder substitution products in coconut milk powder in replacement of soybean powder Suitable and accepted by consumers Taken separately in an aluminum foil bag During the 2 month storage period quality assessments are done every 2 weeks. By measuring moisture color Aw and general microbes and mold yeast. Found that longer duration increased moisture and microbial values. But the number of microbes is less than 1 × 103 colonies pergram which does not exceed the standard of the community product standards.

In this work solar erythemal ultraviolet radiation (EUV) which affects human skin and skin cancer was investigated at Songkhla province (7.2°N 100.6°E). EUV was converted to UV index then the data was used for model development and forecasting of hourly UV index using Artificial Neural Network (ANN). The ANN model has one input layer two hidden layers and one output layer. This input layer consists of extraterrestrial erythemal ultraviolet radiation solar zenith angle aerosol optical depth and cloud index which affect ultraviolet radiation and the output layer is hourly UV index. The results show that hourly UV index obtained from ANN and that from the measurement are in reasonable agreement with root mean square difference of 12.8% and mean bias difference of -2.4%. For forecasting of the hourly UV index the data for 7 days earlier was used for forecasting the next UV index for one day or nine-hour (08:00 am.-16:00 pm.). Multi-layer perceptron and back propagation algorithm were used in the model forecasting. The results show that the UV index from the model forecasting is reasonable agrees with UV index from measurement with root mean square difference of 17.0% and mean bias difference of 0.3%.
