The purpose of this research was to develop innovative cleaning and disinfection products in the situation of COVID-19 and to transfer the production technology of innovative cleaning and disinfection products. The innovative product developed is a semi-liquid alcohol gel. The sample group used in this study was volunteered consisting of 10 people. The research tool was the satisfaction assessment form technology transfer and the development of innovative cleaning and disinfection products in the situation of COVID-19. Data were analyzed using statistical software packages. The statistics used were mean and standard deviation. The results showed that. 1. Innovative cleaning and disinfection products in the situation of COVID-19 developed as an innovation of semi-liquid alcohol gel products. Which has a concentration of 73.0 % v/v 2. Most of the trainees were satisfied with the overall technology transfer. Both speakers places periods facilities knowledge and benefits from receiving services are high. 3. Most of the trainees were satisfied with the technology transfer pattern as well as the duration of the training. Product innovation process Product innovation can be put into practice and product innovation is a guide to careers at a high level.

Piper Betel has been used as a medicinal herb in Thailand for a long period. Not only consumption but Piper Betal also has been used for religious belief and ritual. However the piper leave should be in the good condition without any defect. As a result there are numerous fall-grade leaves to be get rid of from agriculture. Increasing the value-added of this by- product can increase the income. Extraction of bioactive compounds by using alembic is uncomplicated and green without any solvent is required. Two products come out from this process the first one is an essential oil which is expensive. The second product is hydrosol. The piper hydrosol still contained various phytochemicals. In this study total phenolic content was investigated and was found to be in the range 31.16-73.71 GAE mg/g. Total antioxidant capacity was also studied using the DPPH method. The antioxidant activity was 0. 37▁(+)0.11 mg ascorbic acid equivalent/ ml hydrosol. However the piper hydrosol cannot inhibit P.ance S.aureus and S.epideminis. To sum up the piper hydrosol can be used as an ingredient for antioxidant cosmetics rather than antibacterial skincare.

This research investigated the effect of antibacterial activity of Guava leaves extract. Antibacterial activity was determined by agar well diffusion method and test with Staphylococcus aureus Bacillus cereus and Escherichia coli. The results showed that Guava leaves crude extract best inhibited the growth of Bacillus cereus followed by Staphylococcus aureus and Escherichia coli with a mean inhibition zone was 22.0 ±0.3 19.00 ± 0.2 and 14.5 ± 0.3 mm respectively. When comparison antibacterial activity between Guava leaves extract with ampicillin 0.010 mg.

Analytical chemistry laboratory manual was developed for the student in the Division of Enviromental Science and Technology Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon with the aim of promising the laboratory skill of the student in the preparation and standardize the solution gravimetric analysis volumetric analysis and finally spectroscopy analysis. Traditionally in the analytical laboratory pricey analytical grad of the reagent with large amounts and quantities is required. Moreover some of them are toxic and harmful to the environment. These can cause a problem for the university in which the budget is limited. In this work the idea of the small but powerful experiment was conducted. All the chemical and reagent was reduced to 50%. In the final laboratory instead of costly and toxic reagent some substances were replaced with the natural material such as water extraction from purple cabbage. According to the results the developed experiments were accurate enough for practicing the student except for the precipitation titration experiment. In order to evaluate the understanding a mini-project was assigned to the student in the group. By using the developed manual the student can overcome the problem in the lab and the awareness of the environment was also improved.

This research aims to study phytochemicals and potential of Mapok (Parinari anamense Hance) extracts to inhibit germination and growth of Barnyard grass (Echinochloa crus-galli) a common weed in the rice fields. Organic solvents extracted the part of fruits barks and leaves of Mapok included hexane ethyl acetate and methanol. Crude extracts compose of fruit hexane extract fruit ethyl acetate extract fruit methanol extract bark hexane extract bark ethyl acetate extract bark methanol extract leaves hexane extract leaves ethyl acetate extract and leave methanol extract. Crude extracts were tested of phytochemical tested of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition of Barnyard grass. Leaves ethyl acetate extract showed highest inhibit germination and growth of Barnyard grass The leave ethyl acetate extract was separated by column chromatography to yield nine fractions (F1 – F9 fraction) and tested inhibit germination and growth repeating. The results showed that 1. The crude ethyl acetate extracts from the bark of Mapok at a concentration of 3000 ppm showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fraction F8 of leaves ethyl acetate extract showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition.
