| dc.description.abstract | Water was an essential resource for life on earth. Where water was needed according
to the function. Water was needed by living things to survive and water was also needed
for the daily activities of living things. The closest water resource was the river. Rivers
have many functions for humans and the ecosystem in the river. However, most rivers
have been polluted and are no longer suitable for use. So in this research a tool will be
developed that was able to monitor the quality of river water based on IOT, the function
was to monitor the three parameters, namely, pH, turbidity, and temperature. The input
sensors used in this study are the pH meter sensor SEN0161V1, the Turbidity meter
sensor SEN0189, and the Pt100 temperature sensor. Then the input from the sensor was
processed by the ESP-32 microcontroler which is connected to the internet network via
a 4G router and the results will be displayed on the smartphone via the Blynk
application. Measurements were made at three locations. That was, the first location
was on the lake around Puspitek Housing and the measurement results obtained have
an average of: pH (6.37), Turbidity (1283.1 NTU), and temperature (32.05℃ ). The
second location was on the river around Jalan Puri Serpong and the measurement
results obtained have an average of: pH (6.26), Turbidity (1340 NTU), and temperature
(28.87℃ ). The third location was on Sungai Taman Kota 2 BSD and the measurement
results obtained have an average of: pH (6.51), Turbidity (1372 NTU), and temperature
(29.69℃). | en_US |
