Abstract

Syringe Pump is one of the medical equipment that functions to insert medicinal liquid into patients for a certain period of time regularly. The Syringe Pump cannot function as it should. The damage that occurs to the Syringe Pump is caused by an optocoupler sensor error that causes the optocoupler sensor to not be able to push the syringe and the syringe size sensor that does not detect the size of the syringe due to ineffective use and causes the syringe size sensor to not be able to detect the size of the syringe. Therefore, improvements are needed to the sensor part of this tool so that it can detect the syringe as it functions. The repair of this Syringe Pump is carried out by measuring using a multimeter through a specified measurement point, after the results of the calculation are known, followed by the replacement of the optocoupler sensor, then gluing the broken syringe size sensor with glue, and finally testing the function of the tool with the Infusion Device Analyzer (IDA) tool so that the Syringe Pump is successfully repaired and usable. The value obtained from the measurement after making repairs to TP 1 (optocoupler sensor input) was obtained an error of 0% TP 2 (optocoupler sensor output) of 0.5%. TP 3 (syringe size sensor output) of 0%. The tool used for the function test was IDA (Infusion Device Analyzer) and obtained an average of 9.50 ml/h at the 10 ml/h setting. So it was concluded that the tool was functioning well because it was still within the tolerance limit of 10%. And the result of occlusion was 4.7 ml/h which was still at the tolerance limit.

Abstract

This study aims to evaluate the performance of a designed overhead stirrer, specifically focusing on the accuracy of rotational speed (RPM) and time control (timer). Speed testing was conducted using a Fluke 931 tachometer as a reference instrument, while a digital stopwatch was used for time measurement. Speed tests were carried out at four levels: 500 RPM, 1000 RPM, 1500 RPM, and 2000 RPM, with three repetitions for each. The results showed error percentages of 1.27%, 0.033%, 0.133%, and 0.1165%, respectively. All values remained within the acceptable error tolerance of ±10%, indicating that the speed control system operates accurately and consistently. Timer functionality was tested at preset durations of 3 minutes (180 seconds), 6 minutes (360 seconds), and 9 minutes (540 seconds), each repeated three times. The test results showed a time deviation of 0.34 seconds at 3 minutes, no deviation at 6 minutes, and a deviation of 2.67 seconds at 9 minutes. These results indicate that the timer also performs with a high level of precision. Overall, the tested overhead stirrer has met the standards for measurement accuracy in both speed and time. This demonstrates that the device is suitable for laboratory or research applications that require controlled mixing of liquids with precise timing and speed regulation measurement area.

Abstract

This research aims to carry out maintenance, and repair, on the BMV BMO 200 Patient Monitor used at STIKES Semarang. This device is vital in monitoring patients' physiological conditions such as heart rate, blood pressure, body temperature, and oxygen saturation. The identified issue was a blurry LCD screen caused by aged backlight components. The study employed a hands-on approach and direct observation. The stages included damage analysis, replacement of the backlight and polarizer components, and calibration using a fluke meter and voltage measurement. The repair results showed that replacing the entire LCD module restored a clear display and returned the device to proper working condition. This research highlights the importance of regular maintenance and calibration in ensuring the reliability of medical equipment for patients.
