Abstract

In some hospitals, the infusion is still done manually, where medical personnel observe the liquid droplets directly and then control the rate using a mechanical resistor (clamp). This method is certainly far from accurate. An infusion pump is a medical aid that functions to control and ensure the correct dose of infusion fluid given to patients treated. The purpose of this study was to analyze the accuracy of the infrared photodiode as a drop sensor based on the readings of the infusion pump monitoring system. This module consists of a photodiode infrared drop sensor module, a comparator circuit, a monostable circuit, a stepper motor, an L298N motor driver, and an ATmega328 microcontroller. The droplets were detected by an infrared photodiode sensor, then compared with a comparator and monostable circuit as an oscillator developer, and then the flow rate and residual volume readings were generated by the ATmega328 microcontroller. Next, this data has sent to the computer via the HC-11 wireless. The results of the flowrate module measurement show the highest error value of 3% at the 30 ml/hour setting and the lowest error value of 2.5% at the 60 ml/hour setting. Meanwhile, the results of the flow rate measurement using an infusion device analyzer obtained the highest error value of 4% at the setting of 30 ml/hour and 60 ml/hour, and the lowest error value of 0.8% at the setting of 100 ml/hour. Monitoring the infusion pump was designed centrally to facilitate the nurse's task in monitoring the infusion dose given to the patient accurately. Based on this research, the accuracy of the infrared sensor and photodiode is very good by looking at the existing error rate.

Abstract

This study aims to develop and examine the effectiveness of a Canva-assisted audiovisual learning medium on the topic of Climate and Its Changes in elementary schools. The research employed a research and development (R&D) method using the ADDIE model, which consists of the stages of analysis, design, development, implementation, and evaluation. The research subjects were 30 fourth-grade students from SD Negeri Rantau Pangeran and SD Negeri Talang Nyamuk. The resulting product was an interactive video that combines text, animation, images, and audio to visualize abstract climate concepts. Expert validation results indicated a very high level of validity with an average score of 92.80%, covering aspects of media, material, and language. The practicality test obtained scores ranging from 76% to 100%, categorized as practical to very practical. The effectiveness test showed a significant improvement in students’ learning outcomes, as evidenced by an increase in the average pretest score from 54.67 to 82.33 in the posttest, with an N-Gain value of 0.63 (moderate category). These findings demonstrate that the Canva-assisted audiovisual medium is feasible to be used as an alternative for science learning, as it can enhance conceptual understanding, scientific skills, science literacy, and learning motivation among elementary school students.
