| Summary: | Microhydro power plant is a green technology which can be an alternative solution in overcoming the world energy crisis. This technology is a non-depleting and nonpolluting energy source that has been proven be able to provide reliable power in the past and will still one of the most promising renewable energy source in the future. Some microhydro systems those have been implemented in Indonesia were equipped with Supervisory Control and Data Acquisition (SCADA). This additional feature gives benefit to the power plant supervision process. With SCADA, supervision of the Microhydro power
system can be done continuously. Therefore, any problems those might be appear can be detected as soon as possible and then handled appropriately while also maintaining performance parameters of the power plant.
The monitoring and controlling implementation is not away from interactive design of Human Machine Interface. It helps the operator in controlling the plant decision and making correct. In this way, the thesis presents an interface for SCADA to monitor and control parameters in the microhydro power plants and increasing quickens decision making by operator as well as minimizing human error. Evaluation test of HMI is done by survey method, use questioner which addressed to operator. The result of questioner calculated using validity and realibility test. The result of test in earning that value r
account is 0,69. This value has high realibility because r account is bigger than value rt. Where value rt applied is 0,6.
This concludes that HMI which in design have been applicable and capable to
operated as the monitoring and controlling to SCADA system in microhydro power plant.
