The online river water quality monitoring system is a system that can conduct remote monitoring of the main parameters of river water quality intensively and only requires periodic maintenance every month. Two of the several aspects that affect the performance quality of the online river water quality monitoring system are the configuration of the river water sampling subsystem and the user interface display. The river water sampling subsystem can operate in the long run if the inlet pump component has an NPSHa value greater than its NPSHr value, while the user interface is said to be effective if it successfully displays information and observation data that can be interpreted by the user. Based on the test results, the NPSHa value of the inlet pump is greater than the value of the NPSHr and each respondent can fulfill each achievement of each user interface criterion. Thus, the sampling and removal subsystems of water samples can be operated at maximum displacement and the user interface is considered effective in conveying information and observation data to users. There is a problem in the process of removing the sample where 50-150 mL of the remaining water from the previous sample is still found at the bottom of the sample tank, so it is necessary to optimize the drainage of the river water sampling subsystem.
