This project aims to design and build the system programmable syringe pumps to control the microstructure of liquid flow rate for use in laboratory. It can determine the flow rate of the liquid at the 200, 500, 750, 1000, 1500 and 2000 microliter per hour and determine the volume of liquid. The system developed consists of a microcontroller Board series R3-powered Uno Auduino injection tubes. Electronic circuit for driving and computer. From the test results the system flow rate of 500 and 200 microliter brine per hour. Found inaccuracies and flowrates 0.31 ± 0.016 microliter/hour.
