Abstract

Hotplate magnetic stirrer is laboratory equipment used to mix solutions to make them more homogeneous by utilizing a heater and magnetic rod controlled by a high RPM motor, as well as several other supporting components. All these components are assembled into one good tool. In order to produce a good magnetic stirrer hotplate tool, it is necessary to make a planning design to produce a magnetic stirrer hotplate tool that is ergonomic and functional. In designing this tool, several stages of literature study are carried out, designing the tool (to find out the various components needed), designing the tool using a computer, printing the tool, installing components and testing the electrical power of the tool. Based on these steps, the casing design for the Hotplate Magnetic Stirrer tool was successfully created with a length = 230 mm, width = 220 mm, and height = 156 mm. This casing design is able to accommodate all electronic and non-electronic components used, especially high RPM DC motors. It is proven that through this casing design, the high RPM DC motor and other components are installed (attached) well. It has also been confirmed that all installed electronic components have voltage according to their specifications. Keywords: Magnetic Stirrer Hotplate, Design, Motor, RPM, Components.

Abstract

The development of electromedical technology encourages the creation of safer and more efficient surgical tools, one of which is electric cautery. This study aims to design and build an electric cautery prototype based on an Arduino Uno microcontroller equipped with a Liquid Crystal Display (LCD) to display current (0–6 A) and frequency (0–50 Hz) parameters in real-time. The research method uses a Research and Development (R&D) approach, starting from the design stage, prototyping, to functional testing and simple clinical trials on chicken tissue. The test results show that the tool has a high level of accuracy, with a maximum relative error of 3.9% in current and 1.6% in frequency, still within the tolerance limits of the IEC 60601-2-2 standard. Simple clinical trials show that the tool is able to cut tissue well while coagulating so that the wound area remains neatly closed. These findings indicate that Arduino-based electric cautery with real-time monitoring features can be an innovative and safer alternative compared to conventional devices, although further clinical trials with stricter medical standards are still needed.

Abstract

The Fetal Doppler Simulator for calibration is a device designed to ensure the accuracy and reliability of Fetal Doppler equipment in monitoring fetal heart rate. Traditionally, calibration of Fetal Doppler devices has relied on limited methods with relatively high costs. Therefore, an alternative calibration medium that is more economical, practical, and reliable is needed. This simulator functions by generating fetal heartbeat signals with various rhythm patterns, ranging from normal conditions to pathological variations such as tachycardia and bradycardia. The research method applied was Research and Development (R&D), which included needs analysis, design planning, feature integration, prototype construction, and performance testing. The test results showed that the Fetal Doppler Simulator was able to generate stable heartbeat simulations with measurement values that remained within acceptable tolerance limits (≤5%). Based on these findings, it can be concluded that the development of this Fetal Doppler Simulator is feasible and effective as a calibration medium. This research is expected to offer a practical alternative for healthcare facilities to perform Fetal Doppler calibration at a lower cost.
