This paper presents the application of 3D printer to create pet casts. The problem of injuries from falls or symptoms related to bone injuries are symptoms that veterinarians diagnose as potentially treatable by external splinting to allow the bones to fully fuse. Differences in physiology are limitations in splinting and structuring the splint. This research introduces 3D printing technology to help the creation of splints for pets to increase treatment options using innovations or concepts. Study the current state of external splinting treatment methods for pets and design the research method was started by scanning organs to be splinted with a 3D scanner. The 3D images are then used to creat a model for splinting by designing with the Sintratec 3D modeling computer program. Then create the splints by burning plastic powder crystals to harden with a 3D printer and clean the surfaces by sandblasting and polishing. The materials used to create the splints in this study are two types of engineering materials: polyamide12 (PA12), suitable for creating hard splints, and thermoplastic elastomer (TPE), suitable for creating soft splints. Both materials have good mechanical properties and are strong impact resistance, chemical resistance, and high heat resistance. The finished splint pieces can be easily split to the pet model, reducing the steps compared to the normal splints, resulting in a shorter splint time, depending on the location or organs the splints are placed, and reducing the pet stress caused by being restrained during splinting. This research presents the introduction of technology and its advantages to help increase treatment options for pet injuries, which is beneficial to pets and pet owners, and helps veterinarians provide appropriate treatment.

This paper presents eucalyptus, versatile plants that can grow well in almost every area of Thailand. In the future, the demand for eucalyptus wood tends to increase both domestically and internationally because eucalyptus wood has become a major raw material in various industries and is also an important source of energy in terms of biomass fuel production. The research team has designed and built a eucalyptus woodchipper and pelletizer prototype. The machine has a width of $1,300 \text{mm}$, a length of 800 mm, and a height of 900 mm. Inside the machine, there are log conveying systems, a shredder, and a pelletizing system. The shredder uses a 2.2 kW gear motor for shredding logs and a set of 23 blades. The conveying system consists of 4 upper and lower conveyors and uses a 0.2 kW gear motor. The speed is controlled by an inverter. The pelletizing system uses a hydraulic system for compression, which has a hydraulic pump motor as the source of pressure. In the prototype pelletizing and baling test, the optimum speed of the conveying machine was set at 5 rpm, the chopping speed at 320 rpm and the baling pressure at 220 $\text{kg} / \text{cm} 2$. The processing of eucalyptus into the form of wood chips reduces the volume of eucalyptus by 46 percent, allowing more logs to be transported at a time and significantly reducing transportation costs. In addition, the creation of new products from eucalyptus processing will help generate more income for eucalyptus farmers than just cutting and selling eucalyptus.

This paper presents a temperature and humidity control model for use in a pig barn with an evaporative cooling system and fogging system through an application that can be accessed from the Internet. To be compatible with Farming 4.0 and reduce the problem of epidemics in the pig farm. Temperature and humidity are measured through sensors and used to control them through a microcontroller. Users can monitor the temperature, humidity, and system operation via the application. The control system can be controlled with both manual mode and automatic mode.

This paper proposes the experimental of hydropower plant generator system (HPGS). The HPGS using LabView that simulate the veritable flow rates control system is considered, the plant system includes of a permanent magnet synchronous generator (PMSG), a diode bridge rectifier circuit (DBRC) and an Inverter control system. The Inverter control system is used for current and voltage control is the power converter. The controller configured by the function in LabVIEW. In addition, valve control has too installation to computer monitoring a flow rate of water. Also, the obtained parameters are calculated form generator torque characteristic The HPGS using LabVIEW the implemented is explained by comparing the HPGS using Pelton method and the HPGS using standard method.
