Coffee is a critical agricultural commodity to be used to produce a premium beverage to serve people worldwide. Coffee microbiome turned to be an essential tool to improve the bean quality through the natural fermentation. Therefore, understanding the microbial diversities could create the final product's better quality. This study investigated the natural microbial consortium during the wet process fermentation of coffee onsite in Thailand to characterize the microorganisms involved in correlation toward the biochemical characteristics and metabolic attributes. Roasting is another important step in developing the complex flavor/ aroma that make coffee to be enjoyable. During the roasting process, the beans undergo many complex and alternatively change in the physicochemical properties from the gained substances in the fermentation process. The changing in the formation of the substances responsible for the sensory qualities, physicochemical/ aroma attributes as well as the health benefits of the final product. Using the starter culture could also develop the distinguished characteristics of coffee (Research collaboration with Van Hart company)

Microalgae are rich in bioactive compounds that may contribute to the growth of probiotics, which require appropriate nutrients, known as prebiotics, to thrive. This study aims to evaluate the effectiveness of crude extracts from intracellular components residues of the microalga Chlorella sp. KLSc61 in promoting the growth of the probiotic bacterium Lactiplantibacillus plantarum JCM1149 under simulated gastrointestinal conditions. The intracellular extracts were obtained using 70% (v/v) ethanol, and their effects on probiotic growth were tested at concentrations of 0.1%, 0.75% and 1.5%. The growth of Lactiplantibacillus plantarum JCM1149 was assessed using the drop plate method. The findings of this study will provide insights into the potential of Chlorella sp. KLSc61 extracts in enhancing probiotic growth, which could lead to the development of synbiotic dietary supplements containing both probiotics and prebiotics. Additionally, this study may serve as a foundation for further research on the role of microalgal extracts in gut health and immune system modulation.

This project focuses on developing a test device for an AC charger for electric vehicles according to the IEC 61851-1 Annex A standard by simulating the test circuit inside an electric vehicle according to the standard to test the operation of the AC charger. The test topic is related to the communication between the electric vehicle and the charger via a Pulse Width Modulation (PWM) control circuit system and creating an operation manual (WI) to prepare for testing in accordance with ISO/IEC 17025 standards, which are general requirements for laboratory capabilities in conducting tests and/or calibrations. The overall picture of this project is to develop test equipment and create an operation manual by collecting knowledge and various devices and then comparing the data to meet the abovementioned standards to test the Type II AC charger in each state. The test equipment consists of a communication part between the test equipment and the AC charger using a PLC S7-1200 and an HMI to control the operation of the switches in the test equipment circuit, including controlling parameters and displaying results. The equipment used to measure values is an oscilloscope and a multimeter that have undergone a calibration process to comply with the specified standards.

This research aimed 1) to study the problems and needs in the packaging design of the community enterprise group 2) to develop packaging for the community enterprise group 3) to study the satisfaction with the packaging design of the members of the Klong Dan Shrimp Paste Community Enterprise Group 3 Klong Dan Subdistrict, Bang Bo District, Samut Prakan Province, consisting of 9 members The study found that the community enterprise group faced the problem of lacking suitable packaging for souvenirs and had a need to develop packaging that is appropriate for this purpose. The packaging material selected was paper, with a rectangular shape including a handle for portability It can be folded for easy transportation and stacked for storage, while maintaining durability The packaging color used was light brown, and the label color was white The label included the following details: shrimp paste recipe, ingredients, manufacturing and expiration dates, the background of the community enterprise group, a QR code, phone number, a short story, group name, production site, as well as illustrations of the group’s location and red krill. The results of developing packaging for the community enterprise group indicated that the new packaging design increased the credibility of the product, building customer confidence in the product. Regarding the satisfaction with the packaging design among the group members, it was found that Packaging Design 1 had the highest level of satisfaction (x ̅ = 4.57, S.D. = 0.22). Among the aspects, color received the highest satisfaction score (x ̅ = 4.74, S.D. = 0.06), followed by the label (x ̅ = 4.69, S.D. = 0.10), while the lowest was the properties aspect, which was rated at a moderate level of satisfaction (x ̅ = 3.83, S.D. = 1.58), respectively.
