Abstract

A balance centrifuge is a tool to weigh two different samples to determine the balance of the two samples before proceeding to the centrifugation process. The electronic circuit consists of 2 Load Cells and other supporting components, which aim to measure and process heavy data from both samples. In the development of this tool, the Arduino Nano served as the main microcontroller. The Arduino Nano receives data from the load sensor and the tare button to remove the load on the sample container and then processes the data to display the measurement results on the LCD layer. The LED as a balanced indicator when both samples are being weighed. The results of the experiment showed that the developed tool had an average error rate of 1% in the measurement of the weight of the right load cell. Then in the weight measurement of the load cell on the left has an average error rate of 0.3%.

Abstract

This research aims to design a Plasma Blood Separator that can separate plasma from red blood cells automatical-ly using an Optocoupler sensor and a specimen tube cutter. This sistem is equipped with an Arduino Uno as the con-trolling brain, a servo motor to clamp the hose, a DC motor to open the blood bag pressure, a series of push buttons to open the servo, and a buzzer to indicate the completion of separation. After testing the Arduino Uno-based Plasma Blood Separator, all functions can work well by showing results in three trials varying the length of the tube. The var-ied hose lengths are 38 cm, 52 cm, 71 cm. The estimated separation times are 1.16 minutes, 2.17 minutes and 3.4 minutes. In the voltage measurement results, the measurement results were obtained with a small percentage of error with a value of <5% and a high accuracy value with a value of >90%.
