Abstract

This study aims to design and build an Ultrasonography (USG) Phantom as an ultrasound calibration medium with more affordable materials but still meets quality and precision standards. The USG Phantom is designed using two basic materials, namely distilled water and engine oil, to then compare its performance in producing ultrasonic images. The research method used is an experiment with the stages of tool design, phantom manufacturing, and functional testing using Vertical and Horizontal Distance parameters. Testing was carried out with a convex USG transducer at Roemani Muhammadiyah Hospital Semarang. The test results show that the engine oil-based phantom provides a clearer and more stable image compared to water. The results of vertical distance measurements show the smallest absolute error value of 0.01cm (0.1mm) on objects 1–2 with a relative error value of 0.3%, and the largest of 0.09cm (0.9mm) on objects 7–8 with a relative error value of 4.5%. Meanwhile, for horizontal distance, the smallest absolute error value was recorded at 0.14 cm (1.4 mm) on objects 1–2 with a relative error value of 6.8%, and the largest was 0.19 cm (1.9 mm) on objects 2–3 and 4–5 with a relative error value of 9.5%. All vertical and horizontal error values ​​were still within the AAPM TG‑1 tolerance limits, which were ±2 mm or ±2% for vertical measurements and ±3 mm or ±3% for horizontal measurements. Thus, the engine oil phantom can be categorized as a suitable ultrasound calibration medium that is economical, effective, and meets international accuracy standards. This research is expected to be a practical solution for healthcare facilities to perform ultrasound calibration at a lower cost.

Abstract

The Medical Records Unit plays a crucial role in ensuring the completeness and accuracy of patient information in hospitals. A high workload in this unit can impact Performance and service quality. One of the factors that triggers workload is the transition process from a manual system to Electronic Medical Records (EMR), as occurred at Roemani Muhammadiyah Hospital in Semarang City. This study aims to analyze the workload level of Medical Records Unit staff using the NASA-TLX method, which assesses six dimensions: Mental Demand, Physical Demand, Temporal Demand, Performance, Effort, and Frustration Level. This study design was cross-sectional with a total sampling of six respondents from the Filling, Coding, and Assembling Units. Data were collected using the NASA-TLX questionnaire and analyzed based on the rating score and weighting of each dimension. The results of the study show the average value per dimension, namely: Mental Demand (MD) 480, Physical Demand (PD) 464, Temporal Demand (TD) 420, Performance (P) 440, Effort 420, and Frustration (F) 280. The total overall score is 2,504, with a final NASA-TLX score of 78.25, which is classified as a high workload category. The dominant dimension contributing to the workload is Performance (P). These results are expected to be a reference for hospitals in evaluating work systems and supporting the welfare of staff during the digitalization transition period.

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.

Abstract

Component-Level Domestic Content Policy (TKDN) encourages the utilization of domestically produced medical devices; however, their accuracy and safety must be proven. This study aims to analyze the accuracy of domestic infusion pumps using the uncertainty measurement method. A total of four units from four brands (Endo, ESA Tech, Inmedik, and Krisma Care) were tested on the flow rate parameter with variations of 10, 50, 100, 200, and 300 mL/hour. Each test point was measured six times using a calibrated Fluke IDA 5 Infusion Device Analyzer. Data were analyzed through calculations of mean, correction, standard deviation, and expanded uncertainty (k = 2). Based on the analysis results, all TKDN infusion pumps (100%) met the tolerance limit of ±10% in accordance with the PO.002-18 standard and were declared fit for use. The highest correction value of 25.57 mL/hour (8.5%) was recorded for the Endo brand at a setting of 300 mL/hour, while the lowest correction of 0.21 mL/hour (0.7%) was found in ESA Tech. All measurement points across the four brands showed consistency within the permitted tolerance limits, with measurement uncertainty variations between ±0.15 and ±0.17 mL/hour. These findings prove that domestically produced infusion pumps possess accuracy and reliability equivalent to the standards required for clinical use.

Abstract

Calibration of non-invasive blood pressure (NIBP) devices is essential to ensure measurement accuracy in healthcare services. This study aims to compare the performance of two calibrators, XB1000 and Multisim, in testing two NIBP units using the uncertainty analysis method. Measurements were conducted on systolic, diastolic, and heart rate parameters with a total of 16 data points per parameter. The results show that XB1000 achieved a lower total average expanded uncertainty (U95) of 0.421 mmHg compared to Multisim at 0.529 mmHg. Specifically, XB1000 demonstrated the lowest uncertainty across all parameters, with an overall 20.3% improvement over Multisim. Error analysis indicated that systolic measurements had an average error of 2.063 mmHg, diastolic -1.167 mmHg, and heart rate -0.062 bpm. Based on these findings, XB1000 is recommended as the preferred calibrator for NIBP devices, as it provides lower measurement uncertainty and improved accuracy across all tested parameters.

Abstract

This study aims to evaluate the accuracy and effectiveness of several domestic pulse oximeter brands (Elitech, Kaltech, and Endo) and a foreign brand (GE), calibrated using the Prosim SPOT Light SpO₂ Pulse Oximeter Tester. This quantitative study involved three domestically produced oximeters and one imported unit. The oxygen saturation setpoints were varied at 80%, 85%, 90%, 95%, 97%, 98%, 99%, and 100%, with three repetitions for each. Data analysis was conducted using the GUM Uncertainty Method and ANOVA statistical testing. The results show that all oximeters have combined uncertainty (expanded uncertainty, U₉₅) values between 0.58–3.23%, with reading deviations from reference values below ±2%, within acceptable tolerance limits. Kaltech and Endo oximeters demonstrated stable performance with no significant differences across saturation setpoints after calibration. Elitech and GE exhibited higher sensitivity to oxygen saturation variations, particularly at lower ranges. The One-Way ANOVA results indicated that Kaltech and Endo had p-values > 0.05, signifying no significant differences, while Elitech and GE showed p < 0.05, indicating differences between setpoints. Overall, domestically produced oximeters showed equivalent performance to imported devices after standard calibration, supporting the enhancement of Domestic Component Level (TKDN) and strengthening the independence of the national medical device industry.

Abstract

To improve the quality and productivity of agricultural products, farmers use pesticides as chemicals that function to control the growth of pests, diseases, and weeds. Excessive use of pesticides can have health impacts, one of which is impaired liver function because pesticides will accumulate in the liver and cannot be broken down or excreted. This will trigger an increase in the number of free radicals and cause hepatocyte cell damage, as well as increase SGPT levels. SGPT is an enzyme normally found in liver cells, but when there is a disruption in liver cells, the enzyme is released into the bloodstream, causing levels to increase and become an indicator of liver dysfunction. This study aims to determine the effect of the work period of farmers using pesticides on SGPT (Serum Glutamic Pyruvate Transaminase) levels. The examination method used is the Photometric method with Bio System BA 200 with a number of 20 samples. Based on the results of the research, it was found that from 20 samples of farmers using pesticides, SGPT levels were still within normal limits according to the reference value of SGPT levels (Male=42 U/L, Female=32 U/L). The results of the SPSS 23 statistical test with a linear regression test obtained a significant value of p (0.237) > α > (0.05) in the work period, so there was no difference in SGPT levels. Thus, it can be concluded that there is no significant effect between the work period of farmers using pesticides with SGPT levels.

Abstract

Farm fires are a major cause of agricultural loss, leading to the destruction of millions of hectares of farmland. In Indonesia alone, the financial losses due to farm fires were estimated at 221 trillion rupiah in 2015. This study proposes the development of an early fire detection and environmental monitoring system that integrates MQ-7 and photodiode sensors for smoke and fire detection, along with additional sensors for monitoring temperature, humidity, wind speed, and wind direction. The system utilizes Short Message Service (SMS) for communication, which was selected due to its low cost, extensive coverage, and ability to facilitate rapid responses during emergencies. Sensor testing revealed that the temperature and humidity sensors (DHT11) exhibited a temperature deviation of 0.37°C and a humidity error of 2 Percent. The photodiode sensor successfully detected fire at distances of up to 150 cm, especially at night, under low light intensity conditions (0-10 Lux). The GSM communication module showed an average response time of 2 seconds, with a deviation range of 1 to 4 seconds between the sending and receiving of SMS messages. The system demonstrated its effectiveness in detecting fire and monitoring environmental parameters, providing real-time alerts every 10 minutes via SMS. This system offers a reliable, cost-effective solution for early fire detection and continuous environmental monitoring, enabling timely intervention to mitigate farm fire risks.

Abstract

This study evaluates the accuracy of locally manufactured syringe pumps used in Karanganyar District Hospital and analyzes their measurement uncertainty based on the ISO GUM method. Five Indonesian brands (Endo, Esa Tech, Inmedik, KalTech, and Krisma) were tested using an Infusion Device Analyzer at three flow-rate set-points (10, 50, and 100 ml/h) and an occlusion test at 100 ml/h. All devices met the standard tolerance limits (±10% and <20 psi). The expanded uncertainty ranged from ±0.09 to ±0.70 ml/h, indicating reliable measurement performance. KalTech and Inmedik demonstrated the most stable accuracy, while Esa Tech tended to over-read at low flow rates and Krisma showed significant under-reading at high flow rates, though still within acceptable limits. Statistical tests confirmed no significant differences among brands. Overall, the findings support that Indonesia-made syringe pumps meet technical requirements and strengthen the implementation of the national TKDN policy for reducing dependence on imported medical devices.
