Abstract

Background. The development of electromedical technology in the healthcare field is increasing. However, the measurement of liquid samples in the pipetting process is still done manually which makes it highly contaminated from human hands. A Liquid Handling System (LHS) is a device used to automatically transfer fluids to prevent contamination. 3D Printing is a tool used to create creative design objects using filament material. The mechanism of this tool is similar to that of a liquid handling system but is simpler and has a smaller capacity. In the future, Research Purpose. To determine 3D printing modification of liquid handling system for pipetting system process in the medical area. Research Method. This research uses the research and development (R&D) method by designing and constructing a Prototype Liquid Handling System with a modified 3D Printing 3-axis, placing measuring cups and sample tubes, and designing G-Code programs and servo motor coding to test the capabilities of the designed Prototype Liquid Handling System. Findings. Based on the functional test results of the liquid handling system using NaCl solution, the pipetting results were 0.82 ml with a processing time of 5.6 seconds. The electromedical device has a percentage error rate of 2.4% with a pulling force of 6.56 N and an injection pressure of 8.44 Pa. Conclusion. This electromedical device will be able to automatically process extraction fluids or pipetting processes with high accuracy.

Abstract

Background. Modern vehicles must prioritize comfort and safety, including the suspension system. While passive suspension systems are common, they struggle with excessive vibrations on uneven roads. Semi-active and active systems address this but are costly and complex. To solve this, a Variable Geometry Suspension (VGS) prototype was developed, integrating an active actuator into a passive system to adjust its geometry, providing performance comparable to active suspension systems. Research Purpose. This study aims to examine the effect of single-link angle variations in the Variable Geometry Suspension (VGS) prototype on bumpy roads to determine the most comfortable single-link angle. Research methods. This research employs a Research and Development (RnD) method by testing the single-link angle at 0°, 90° (reference angle), and 180°. Data collection was conducted by introducing road disturbances in the form of a bumpy road. Findings. The testing results showed that the lowest Root Mean Square (RMS) value of the sprung-mass was at a single-link angle of 90°, with an RMS value of 0.72 m/s². This indicates a "Fairly Uncomfortable" level based on ISO 2631, with the damper on the unsprung-mass (ct) and tire stiffness (kt) disregarded, as well as the weight of the sprung-mass. Conclusion. The VGS prototype's response to changes in the single-link angle on bumpy roads varies. However, the system effectively reduces vibrations at all angles, stabilizing the vehicle's body (sprung-mass) as the wheel (unsprung-mass) moves over uneven surfaces.
