The dyeing industry both of business size and household size where the remaining water from the dyeing process is dumped into pipes and flows into natural water sources causing sewage problems. Therefore a column type wastewater treatment system has been developed by using a filtration system along with an adsorption system. The materials used to treat the wastewater from dyeing are gravel sand charcoal from wood and activated carbon from coconut shell. The study was conducted on the synthesis activated carbon from coconut shell using for color and molecules adsorption. The amount of activated carbon from coconut shell was varied at 200 400 600 and 800 g applying with filter media and other adsorption materials taking 1 hour to treat the wastewater from dyeing. The parameter using to measure water quality consisted of color value pH suspended solids conductivity turbidity value COD and TKN to indicate the water quality before and after treatment evaluating the efficiency of the wastewater treatment system. The best ratio that can treat the color is the formula containing 800 g of coconut shell activated carbon. It was able to treat the color equal to 5.94 SU or 99.43 percent compared to the wastewater before treatment.

The research team had thought of studying the properties of natural fermented Maieng extract as an important antioxidant substance in cosmetics. to transfer to the Sakadee community Nan Province. The research had started at the development of a natural fermentation process studied the extraction process yielding important substances from natural Miang fermentation and evaluated the antimicrobial activity and anti-oxidation of bioactive extracts. The outcome studies were transferred including the extraction process of bioactive compounds and formulations in skin cream cosmetics. It was demonstrated that natural fermentation by adding clean disinfected water or fermentation with a stock of Lactic acid bacteria isolated from Miang fermented water in anaerobic conditions for 2 weeks the efficiency and characteristics of fermentation were not significantly different. In the process of extracting bioactive substances with ethanol by soaking the extracts with water and virgin coconut oil with the maceration method at room temperature and shaking in 80% ethanol for 3 hours resulted in a high content of antioxidant properties. In addition the developed approach influenced the characteristics of fermented Miang meat well accepted by the users. This fermented Miang extract was acceptably used to make fermented Miang products for further sale. With the potential of Miang fermented extract in antimicrobial activity therefore the extract has been made a face cream product and tested for user acceptance. From preliminary testing it was found that the facial product with the fermented Miang extract to be satisfactory and did not cause allergic reactions. It had the ability to reduce wrinkles could clear face and transferred to the community focusing on the needs of users in the community. The community could make such face cream products and processed the commercial Miang extract cream that are acceptable to general consumers.

Talad Noi Community is an ancient Chinese community found since the beginning of Rattanakosin. There are many important historical values in this area but also there are still many problems caused from the prosperity of the urban community leading to the process of swallowing up until disappeared from the development of big cities like all old towns. Therefore these solutions can to be promoted by utilizing the applications to promote minor market community activities. To the development of applications it can be concluded that the overall system users both general users and administrators are at a very good level. In terms of the ability of various systems administrators are satisfied with the user manual of the system that is clear and easy to understand as much as possible. As for working according to various functions in the system administrators are satisfied with setting the password using check and the satisfaction system of users. In addition general users satisfy with the overall systems as their convenience and speed.

This research is a qualitative research. Considering the situation of the elderly in Thailand B.E. 2016 and the study of the context of the community with a tendency to increase the proportion of the elderly population together with the problems and obstacles that there are still needs to participate in recreational activities. In this regard there were 38 key informants chosen by a purposive sampling method for each target group. The selected informants consisted of 30 elderly people between 60-69 years old 2 neighbors 2 community leaders 2 family members and 2 government officials. Due to the outbreak situation of COVID-19 the target group has to be adjusted accordingly. There were only 10 elderly people who were willing to be interviewed by phone. These informants are those who resides in Nang Loeng community Phra Nakhon District and Pom Prap Sattru Phai District Bangkok. The data was therefore collected by telephone interviews. It was found that the elderly’s highest average needs for recreational activities were the top 3 categories accordingly as follows: 1.the category of games sports and play 2. dance and 3. singing and music. The results of the research also showed a clear nature of the activities; that is these three types of recreational activities involved body movement fun activities and those that demonstrated their abilities and skills. It can be seen that these three types of recreational activities involved physical movement as the main component of exercise and dancing as well as gestures and posture while singing or playing music. This helps promote physical health mental health and a good quality of life for the elderly. The result also showed that the activities that the elderly most frequently participated in during the recent period were games sports and plays followed by singing and music and dance. The problems found from participating in recreational activities among the elderly was the insufficiency of equipment and facilities followed by the problem of inappropriate places for participating in recreational activities and the problem of inappropriate activity period. (too little or too much time).

The objectives of the research were: 1) to develop and find the effectiveness of learning activities based on the concept of design thinking process to promote self-development of undergraduate students; Rajamangala University of Technology Phra Nakhon 2) to study the satisfaction of learners with learning activities based on the concept of design thinking process together with learning management. The samples used in the research were 30 first-year students who were accompanied by specific selection The tools used in the research were an evaluation form. and the student satisfaction assessment form The results of the research showed that 1) learning activities based on the concept of design thinking process together with learning management to promote self-development of undergraduate students Rajamangala University of Technology Phra Nakhon It focuses on students understanding of the problem through interviews with those who involved in a problem or problem situation rely on working together There is a plan to conduct research analysis to exchange knowledge and experiences. Develop a piece or work to solve problems based on knowledge and ideas. Science and technology consists of 5 steps: 1) preparation and in-depth understanding 2) problem framing stage 3) planning/brainstorming stage 4) prototyping stage and 5) testing and evaluation stage. learning activities The efficiency was 81.28/83.86 higher than the 80/80 criteria. 2) The self-development assessment was at a good level. 3) The students satisfaction with the learning activities based on the concept of design thinking process in conjunction with overall learning management was at a high level.
