dc.description.abstract | Mineral Water Vending Machines (MWVM) have become a popular solution for
providing easy and fast access to quality drinking water. This research aims to
analyze the quality of well water sources and river water in MWVM based on solar
power as an energy source for machines to operate independently and
environmentally friendly. This system is equipped with a Total Dissolved Solids
(TDS) sensor, pH sensor, temperature sensor and color sensor to identify key
parameters in measuring water quality. The TDS sensor is used to measure total
dissolved solids in water, the pH sensor is used to measure the acidity or alkalinity
of water, the temperature sensor is used to measure water temperature, while the
TCS34725 color sensor is used to detect color changes resulting from water by
providing RGB value readings (Red, Green, Blue). Well water and river water are
filtered using a Reverse Osmosis (RO) filter as a water filter and purifier. The TDS
sensor is calibrated using a TDS meter, the pH sensor is calibrated using a pH
meter and the temperature sensor is calibrated using a thermometer. By producing
an average that complies with drinking water standards. The results of measuring
well water after filtering had an average TDS value of 41.9 ppm; pH 7.34; the
temperature is 28.87°C and the color sensor value has an average RGB value (Red
841.4; Green 586.4; Blue 407.8) while the river water after filtering has an average
TDS value of 42.9 ppm; pH 7.36; the temperature is 28.96°C and the color sensor
value has an average RGB value (Red 840.6; Green 586.5; Blue 408.6). From these
results, well water and river water filtered using MWVM have met several physical
and chemical parameters according to the Regulation of the Minister of Health of
the Republic of Indonesia Number 492/Menkes/Per/TV/2010 concerning Drinking
Water Quality Requirements. | en_US |
