Bone tissue scaffolds are made from biomaterials that support rapid repair and healing. Scaffold fabricators have produced materials that are able to degrade a biosystem or human body excellently. Thus, this work aims to study the optimization of materials, shape, and the 3D printing process with FDM. Finite element analysis is also used to predict mechanical properties of the scaffold and find the optimal shape and pore size. However, the materials studied include PLA, PCL, and HA.

Nowadays, automobiles are the most widely used form of transportation. This increases the risk of accidents. Therefore, car users prefer to get insurance to reduce the risk in the event of an accident. As for the insurance company, the company will be responsible for damages according to the conditions of the policy. One of the duties of a company's claims department is to procure spare parts to control costs. However, in the case of compensation, there may be erroneous operations, such as ordering the wrong parts or ordering more than necessary. Currently, insurance companies do not have a very efficient management system. This research aims to develop a system for managing and storing automobile parts for insurance companies. The system is designed to be able to track the status of spare parts from storage to disbursement. It uses barcode technology to increase accuracy and reduce errors in data recording. Such a system will help insurance companies manage spare parts systematically, reduce unnecessary costs, and increase efficiency in providing services.

This research aims to develop a horse treat product that meets the nutritional and health needs of horses by using natural ingredients with beneficial properties, such as oats, wheat flour, corn flour, and organic molasses. These ingredients are rich in fiber, vitamins, and essential minerals for horses, while also enhancing digestive efficiency, reducing the risk of colic, and providing an appropriate energy source. The treat is designed with a shape suitable for a horse’s chewing behavior and is infused with Thai fruit flavors, such as pineapple and ripe mango, to attract horses and make consumption easier. The production process emphasizes cleanliness and safety by selecting organic ingredients and avoiding harmful preservatives. The packaging is designed to maintain product quality for an extended period, prevent moisture, and be convenient for horse owners to use. Additionally, the treat can be used as a reward during horse training, helping to strengthen the bond between the horse and its owner while reducing equine stress. This product serves as both a health-boosting snack and an effective training tool, making it suitable for horses that require highly nutritious supplements. It also provides a new option for horse owners seeking a safe and beneficial product for their horse’s overall well-being.

Sugar production from sugarcane is a complex process that requires precise control. One of the major issues is sugar loss, which can result from various factors, particularly "burnt cane," before being sent to the mill. This affects the quality of the sugarcane and the efficiency of sugar extraction, along with the performance of the machinery and the properties of the cane, which impact the amount of sugar extracted. This study aims to analyze the factors that influence sugar loss in the sugar production process, using quantitative data from a sugar factory. Nine variables were examined, including mechanical efficiency, machine downtime per day, cane waiting time per day, sand content in cane juice, pol extraction efficiency, overall working time efficiency, cane juice purity, cane sugar content (C.C.S.), and burnt cane. The data were analyzed using correlation analysis to examine relationships between variables and regression modeling to predict sugar loss. The results showed that mechanical efficiency, cane sugar content, and the amount of sand or impurities in the cane juice were significantly correlated with sugar loss. Mechanical efficiency had a direct relationship with the amount of cane milled, which improved sugar production. On the other hand, burnt cane, or cane that was burnt before harvesting, resulted in reduced sugar extraction and impacted the quality of the sugar. Therefore, reducing sugar loss in the production process can be achieved by improving machine efficiency, reducing impurities in cane juice, and managing burnt cane, which will improve sugar production efficiency in the future.
