This research investigates active packaging films made from polyvinyl alcohol (PVA) and nanocellulose fibers (NFC), incorporating silver nanoparticles (AgNPs) synthesized from Terminalia chebula extract, which possesses antibacterial and antifungal properties. The developed films were tested for their mechanical properties, microbial inhibition, and biodegradability. The results showed that the addition of AgNPs from Terminalia chebula enhanced product protection and effectively extended the shelf life of strawberries while being environmentally friendly.

This project presents the development of a "Smart Cat House" using Internet of Things (IoT) and image processing technology to facilitate and enhance the safety of cat care for owners. The infrastructure of the smart cat house consists of an ESP8266 board connected to an ESP32 CAM camera for cat monitoring, and an Arduino board that controls various sensors such as a motion sensor in the litter box, a DHT22 temperature and humidity sensor, an ultrasonic water and food level sensor, including a water supply system for cats, an automatic feeding system, and a ventilation system controlled by a DC FAN that adjusts its operation according to the measured temperature to maintain a suitable environment. There is also an IR sensor to detect the cat's entry into the litter box and an automatic sand changing system with a SERVO MOTOR. All systems are connected and controlled through the Blynk application, which can be used on mobile phones, allowing owners to monitor and care for their pets remotely. Cat detection and identification uses image processing technology from the ESP32 CAM camera in conjunction with YOLO (You Only Look Once), a high-performance object detection algorithm, to detect and distinguish between cats and people. Data from various sensors are sent to the Arduino board to control the operation of various devices in the smart cat house, such as turning lights on and off, automatically changing sand, adjusting temperature and humidity, feeding food and water at scheduled times, or ventilation. The use of a connection system via ESP8266 and the Blynk application makes it easy and convenient to control various devices. Owners can monitor and control the operation of the entire system from anywhere with internet access.

Board games are becoming a popular way to connect people, especially in cafés and social spaces. Meanwhile, Thailand’s diverse tourism—rich in nature, culture, and regional charm—attracts visitors worldwide. We combine the thrill of travel with board games to showcase hidden gems in a fun and educational way, leading to the creation of “C(4)ulture Adventure Board Game.”

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.
