This study explores the design, production, and installation of 3D-printed modular artificial reefs (3DMARs) at Koh Khai, Chumphon Province, Thailand, through a design thinking framework. Collaborating with SCG Co., Ltd. and the Department of Marine and Coastal Resources, the research establishes design criteria and installation methods, utilizing content analysis and qualitative research. Key principles such as modularity, flexibility, environmental sustainability, and usability are identified. The user-centered approach optimizes the 3DMARs for transport and deployment, enabling local community involvement and fostering sustainable practices. The modular design supports scalability, enhancing marine habitats and coral larval settlement. Furthermore, underwater monitoring techniques enable site-specific data collection, allowing for the generation of digital twin models. This research offers a practical framework for marine ecosystem restoration and empowers coastal communities in Thailand and beyond

The Department of Engineering Education at KMITL offers courses in power electronics laboratory practices, which require the use of expensive imported training kits. This results in a loss of national revenue due to the purchase of these imported kits. Therefore, the developers propose a power electronics training kit that offers equivalent or superior functionality to the imported ones while being more cost-effective, making it suitable for student experiments.

The objective of this experiment was to determine the effect of nitrogen and potassium concentration combination with photoperiod on the growth of Viola in a plant factory to increase the quality of the products, reduce the production time and increase the production cycle throughout the year. The experimental plan was 3x3 Factorial in CRD with nine treatments and three replications (six plants per replication). The factor of this study was two factors; the first factor was three different concentrations of nitrogen and potassium in ratios of 1:1, 1:2 and 2:1. The second factor was the application of different photoperiods. There were 1) 24-hours photoperiod, 2) 8-hours light/16-hours dark photoperiod (Induced flowering state: 13-hours light/11-hours dark photoperiod) and 3) 5-hours light/3-hours dark photoperiod. Controlled temperature at 25 °C, the EC=1.5-2.0 mS/cm and the pH=5.8-6.5 in all treatment. The result showed that the concentration of N: K in the ratio of 1:1 combined with 24-hour photoperiod was the most vegetative growth and also maximizes reproductive growth. The overall great sensory evaluation was an acceptable level and suitable for cooking or decorating dishes. Therefore, the concentration of N: K in the ratio of 1:1 combined with 24-hour photoperiod is the best treatment to increase the quality of the product, reduce the production time of viola flowers in each cycle from 90-100 days down to 43-45 days which is good for farmers.
