The purposes of this research were 1) to study the purchasing behavior of readyto- drink coconut juice. 2) To study the marketing factors of ready-to-drink coconut juice of consumers. 3) To study the relationship between personal factors and behavior in purchasing ready-to-drink coconut juice and 4) to study the relationship between marketing factors and purchasing behavior of ready-to-drink coconut juice. This was a quantitative research using questionnaires as a tool to collect data from a sample of 400 people without gender who are 20 years of age or older and live in Bangkok. The statistics used in the data analysis consisted of percentage mean standard deviation and correlation was determined by chi-square statistical test. The results showed that 1) most consumers behaviors had a reason to choose ready-to-drink coconut juice as a healthy drink with a purchase frequency of 1-2 times per week. The amount of purchase per time is at 1 bottle / box / bag which the purchase cost per time is 51- 100 baht and most of them choose to buy products from convenience stores. 2) The overall marketing factors in purchasing ready-to-drink coconut juice of the sample group were at the highest level. When considering the factors by aspect they were found that almost all aspects had the highest level of opinion in terms of price products and distribution channels respectively. Except for marketing promotion it was found that the sample group had a high level of opinion. 3) The relationship between personal factors and behavior in purchasing ready-to-drink coconut juice found that gender was related to the purchase frequency and the cost of each purchase. The education level was related to the reason for the purchase purchase frequency and cost of each purchase. Age occupation and average monthly income were related to all aspects of purchasing behavior which were the reason for purchase frequency of purchase location of purchase quantity of each purchase and cost of each purchase were found to be (P ≤ 0.01) and 4) the relationship between marketing factors and purchasing behavior of ready-to-drink coconut juice found that the overall marketing factors were related to behavior in all aspects which were the reason for purchasing purchase frequency purchase location quantity of each purchase and each purchase cost were found to be statistically (P ≤ 0.05)

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.

This research aims to study the degree of public participation in the management of tourist attractions in the the Ton Maphrao sub- district Mueang Phetchaburi District Phetchaburi Province to compare the level of public participation in the arrangement of tourist attractions in the community with various personal factors and to study the guidelines for public participation in the management of tourism attractions in the Ton Maphrao sub- district. The data collection was conducted between October 2021 and September 2022. The mixed research method was employed: both qualitative research with in- depth interviews and focus- group interviews and and quantitative research. The sample group in the research was people in the community. Both random sampling and convenience sampling was used to collect data. The results of the study indicate that the participation of people in the community mainly takes the form of community members and government agencies brainstorming to solve problems together attending meetings and organizing activities within the community. In addition people in the community participate in coordinating to educate or provide services to tourists. They also create publicity for tourist attractions within the community which involves the establishment of a committee to operate within the community and volunteers who participate in coordinating with departments within the community. The local government supports this activity with funds and equipment and has strong coordination with external agencies so that people in the community receive new information and knowledge from community activities have pride in the community and benefit from the management of tourist attractions within the community.

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.

Young coconut shells are a byproduct after processing coconut juice which can be used to produce a solid-fuel. This fuel from the coconut shell is an alternative source instead of using firewood or charcoal made of timber in the natural forest. The solid-fuel from young coconut shells was prepared by using a wet glue powder as a binder then was compressed by using a briquette machine. The black coconut briquette was stable after exposure to the sun. The average of the briquette combustion rate was at 11.24 g /min. There is no eruption smut smoke and odor by using the young coconut shell briquette yo start a fire. To sum up a young coconut shell has a high potential as an alternative biomass material for producing a briquette especially for commercial. This solution can increase the reduction of haze weather in the sight of solid waste incineration and also global warming.
