This module uses the L298N motor driver as a stepper motor controller. The choice of the infuse pump setting is the volume setting from 100 ml to 500 ml and the speed setting of 30 ml/hour, 60 ml/hour, and 90 ml/hour. The author uses the ATMEGA 328 microcontroller as a droplet controller per minute, volume and speed. Occlusion in this device is in the detector of the droplets that are alerted in the presence of a sound buzzer. This tool is also equipped with monitoring volume, rpm and speed on a wireless-based PC using HC-11 as a transmission from module to PC. This tool is equipped with occlusion. The flow rate data processing in IDA from infusion got the highest error result at the setting of 30 ml/hour which was equal to 5.97%. the highest error for the calculation of droplets in the module is the setting of 30 ml/hour which is equal to 32% and manually at setting 60 which is 23%.

I. INTRODUCTION The infusion pump is a medical aid designed to control and regulate the administration of intravenous fluids to patients who are in care. The most important element in the infusion pump is a system for controlling the droplet speed of intravenous fluids using an electronically controlled pumping mechanical system [1] [2]. Based on the reference from the world health center in 2011, it was explained that the Infusion pump is also a tool that is useful for regulating the amount of fluid or drugs that enter the patient's blood circulation directly through the vein. To maintain the patient's condition to be monitored and facilitate the nurse in administering intravenous fluids. Therefore, manual infusion devices are less effective because there is no monitoring of indicator fluids in the nurse's room. And then, nurses who assist in meeting the needs of intravenous fluids in patients experience difficulties and limitations of nurses who cannot always be next to patients at any time become a problem with using the infuse pump manually. Because of this, many innovations in the infuse pump tool serve as reminders for nurses about the availability of intravenous fluids and make it easier to control, nurses can arrive on time and the patient's family is not confused looking for the presence of nurses during the patient's fluid replacement process. In 2014 the research on "Monitoring of Atmega16 Microcontroller Based Infusion" made by Ardiyanto Iqbal Nugroho, from this final project developed a tool that detects flow velocity and fluid volume at infusion. This tool uses an Atmega 16 microcontroller with an LCD display and is equipped with a buzzer indicator, in this tool the buzzer will sound if the droplet speed is slower or faster 4 drops per minute than specified. The LCD displays droplet data per minute. This tool is equipped with monitoring on this tool is the speed of flow rate and volume of fluid [3]. This tool does not use a PC as a monitoring or monitoring device for an infuse pump. In the same study in 2015, Putra Wira Merdeka conducted a study entitled "Detection of Infusion Fluid Consuming with Monitoring to Computers" having a manual infusion
