The research team aimed to develop a prototype and an online marketing concept of Homonoia riparia Lour. Extracts which is of interest to the Ban Suak community. Because of the needs of Bo Suak community who are cultivating organic fruit and medicinal plants. The Homonoia riparia Lour. were selected and extracted for cosmetic products. In the study Homonoia riparia Lour. extracts were extracted and tested for their bioactive compounds having antimicrobial properties and anti-oxidation. Initially dried Homonoia riparia Lour. leaves were extracted with 80% ethanol at a concentration of 5000 ppm had moderate antimicrobial properties for Pseudomonas sp. and Penicillium sp. For antioxidants activity it had antioxidants with DPPH method by performing free radical scavenging IC50 at 0.198 ppm. It was thus promoted for sale on the online market as introduction of Homonoia riparia Lour. extract and facial cream products with Homonoia riparia Lour. extracts. By managing the online market that already exists in the community an online market of Homonoia riparia Lour. extract for Ban Suak community Nan province via Facebook page was developed. The formation of online marketing by presentation of the extraction and the plant’s contents was including the events in many forms such as articles pictures videos questionnaires etc. Moreover the community could organize Facebook Events to invite interested people to join and learn watch demonstrations for the activity. They could try out test for and buy products. The outcome online marketing strategy of Homonoia riparia Lour. extract via Facebook Page can create success marketing that help consumers to gain knowledge and understand the benefits of the product as well. It also proposed guidelines for improving the process of creating an online marketing model based on the principles of Smart Goals SMART Goals for community people working in stores. The Smart Goals includes Specific Measurable Achievable Realistic and Timely. Based on the management principles and the acceptance of Ban Suak community in Nan province it should help create a way to reduce the cost of production guidelines to help reduce the problem of stocking herbs and offering fresh ingredients available all the time together with a verifiable tax invoice. It made it easy to understand the management approach to reach the target audience. As a result customers can come to find themselves and be able to conveniently access the products from anywhere. It thus introduces a performance review approach channels that customers can reach. Numbers of customers who visit the website or fan page will be able to present products and provides services easily.

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.

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 aimed to study the causes of changes in water quality and compare the water quality in Khlong Bang Khen Mai when the seasons and sampling points are different. These factors may cause a change in water quality. A total 50 of water samples were collected from 5 sampling points each point approximately 300 meters apart for a total distance of 1.5 kilometers. They cover three seasons such as winter (October 2020 to February 2021) summer (March to May 2021) and rainy (June and July 2021). Three parameters of this research which consist of both the chemical and physical quality parameters are pH Dissolved Oxygen (DO) and Electrical Conductivity (EC). The result shows that the average pH has ranged from 7.10 - 7.74 the dissolved oxygen (DO) was in 1.80 - 2.84 mg/L and the electrical conductivity (EC) was in the range of 327 - 517 μs/cm. A two-way analysis of variance is a statistical method used to compare the water quality in Khlong Bang Khen Mai. The results indicate that the test differences between seasons affected the change in water quality in all parameters with a statistically significant level of 0.05. Afterward the comparison of multiple comparisons by Scheffes method showed that the pH and dissolved oxygen (DO) in the rainy season were significantly different from winter and summer at the level of 0.05. For the electrical conductivity (EC) there was significant differences between summer and winter at the 0.05 level.
