Abstract

Water is one of the natural resources which is very important for living things to sustain life. The daily life of living things is inseparable from the use of water, one of which is for consumption or drinking. Water that is good for consumption by living things is water that is not polluted by anything. Contaminated water is very dangerous for the health of living things, because it has toxic properties (toxic). This research was conducted in one of the watersheds in Malang City. This study aims to determine the feasibility level of water consumption by using the parameters of temperature, TDS, pH, and turbidity using fuzzy Tsukamoto as a decision support system. The sensors used include, the DS18B120 Probe temperature sensor with an average error rate of 1.26%, the TDS SEN0244 sensor with an average error rate of 3.59%, the MSP 340 pH sensor with an average error rate of 5 , 85%, and the last one is the analogue turbidity sensor B12008 with an average error rate of 37%. Water data obtained from the four sensors is processed using fuzzy Tsukamoto as a decision support system which refers to the Regulation of the Minister of Health of the Republic of Indonesia Number: 416 / MENKES / PER / IX / 1990 to determine the feasibility of water. From the results of the Tsukamoto fuzzy calculations in this study, the accuracy of Tsukamoto fuzzy in determining the quality of water suitable for consumption is 70%.
