Abstract

A collimator simulator which is an accessory in radiology equipment, has been made. This simulator was created as a learning medium to complete students' understanding in studying x-rays as part of electromagnetic waves. The research is divided into two stages, namely the manufacture of simulators and implementation as teaching materials. The collimator simulator is equipped with blades that are used to limit the radiation field area. In this study, collimator lamps were used to see the area of the field. The simulator is equipped with a motor to open and close the radiation window. The results of the implementation to students stated that students agreed that the collimator simulator learning media helped students to better understand the material. Keywords: learning media, collimator, radiation field area

Abstract

Currently technology is highly developed and supports many new innovations. The most innovation is wireless technology and voice recognition. One of the widely used wireless technology is Bluetooth. By utilizing Bluetooth connectivity and voice recognition applications on smart phones, it can be used to control electronic equipment. In this study, voice recognition applications and Bluetooth connections will be used on smart phones to control electric wheelchairs. This research begins with designing an electric wheelchair. For Bluetooth communication using the HC-05 Bluetooth module. The wheelchair was developed by modifying conventional wheelchairs to become electric. The user or patient will control the wheelchair using his smart phone through the voice recognition application. Commands in the form of voice that will be sent by the smart phone and received by the HC-05 Bluetooth module, then become input for the Arduino microcontroller. The microcontroller will then process the input data and will instruct the motor driver to give instructions to the wheelchair driving motor. The electric wheelchair's voice control system with a Bluetooth connection can work quite well. The Bluetooth connection used in this electric wheelchair voice control system works optimally and well at a distance of <10 meters, the connection starts to drop at a distance of 10 to 23 meters, and the connection is lost when the distance is 30 meters. The results of the voice recognition test on voice commands were successful with an accuracy of 85%. The total test is 100 orders with a total error of 15 orders.

Abstract

During the Covid-19 pandemic, DNA amplification technique – the Polymerase Chain Reaction (PCR) method became the gold standard for virus diagnosis and measuring the amount of viral target nucleic acid in a clinical sample and delivering quantitative results. This PCR method is implemented as Thermal Cycler or PCR machine. One of the main components in the Thermal Cycler is the heater. Three heaters, such as: Peltier Device 12715, Ceramic Heater PTC 12 VDC, and Customized Heater 12 VDC were tested for their performance by being connected to 3-well aluminium block. Two pieces of PTC Ceramic Heaters 12 VDC with a total power of 120 W showed the best performance compared to the other 2 heaters and were able to provide a heating ramp rate of 0,13 /second.

Abstract

Medical imaging is one method that is widely used to provide information about the physical parts of the body for diagnosis and therapy. This research is an initial study to find appropriate technology to record medical imaging results in the form of photos and videos so that they are ready to be distributed to support the telemedicine process. This research was conducted by studying literature on the equipment that might be used for the screen capture process, followed by making a prototype of the tool to be used as FGD material. During the FGD process, discussions were held with radiology specialists and gynecologists, nurses and technicians to find out the impact of this tool. The results show that it is possible to distribute medical images using screen capture techniques. This research is the first step for the development of medical image distribution.

Abstract

Learning instrument is an important things in the learning process. Mechatronics systems that have complex circuits and controllers are not easily understood by Level 1 and 2 Students. This research applies the R&D method of Sugiyono to produce sorting machines that are easy to use and learn. The Pixy2 CMUcam5 camera is used for color detection. The controller circuit are used is Karnaugh Map circuit using Digital IC (NOT-AND-OR) and Arduino Uno. The color combinations processed in Karnaugh Map controller circuit are sorting 1 color (Red-R/ Green-G/ Blue-B), 2 colors (R&G/ R&B/ G&B), and 3 colors (R&G&B). Results of this sorting machine are can be operated easily, reprogrammed for both object color detection and DC motor & servo motor control, and rebuilt for the Karnaugh Map series. Validation of this study resulted in improvements to the initial turntable design which was improved with a timing belt mechanism to stabilize the turntable rotation. Lighting of indoor/outdoor does not affect the system because the Pixy2 has an internal LED so that the color is detected properly. The results of sorting with the final turntable design have good performance with an average success of 97.96% and a standard error of 0.58.

Abstract

Autoclave is a tool used to sterilize medical instruments such as surgical knives and scissors. The process of autoclave sterilization is to provide heat energy to the autoclave. Hot steam will rise into the closed chamber. The control system will monitor the temperature until the required temperature is reached (121-124 °C). Temperature measurement in the autoclave is done using a thermocouple sensor. Temperature testing is done by comparing temperature measurements using a thermocouple and a mercury thermometer. Testing with a thermocouple produces output that is linear and comparable to measurements using a mercury thermometer. The correlation coefficient value of the measurement results using a mercury thermometer is 0.99982 and a thermocouple is 0.99894. Furthermore, the test is carried out by looking at the change in the line on the indicator tape to the length of time for sterilization in the autoclave chamber. As a result, the longer the sterilization time, the change in the line on the indicator tape will look darker, which indicates the sterilization process is going well.Keywords: temperature measurement, autoclave, type K thermocouple, indicator tape
