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)

An automated hydroponic system for household use has been developed to cater to individuals with limited space who wish to conveniently and easily grow their own salad greens at home. This system is designed to automatically control nutrient delivery by setting appropriate electrical conductivity (EC) and pH levels tailored to the specific salad greens being grown. It includes artificial lighting to enable cultivation in confined spaces with insufficient sunlight and is more cost-effective than similar systems available on the market. System testing revealed that the automated control of EC and pH values performed effectively, achieving the preset levels within 30 minutes and maintaining them consistently throughout operation. In an experiment growing green oak lettuce using a simulated balcony setup, the plants demonstrated a higher growth rate compared to conventional methods, particularly when artificial lighting was used.
