Abstract

Various public service institutions have increasingly improved their service quality. The existing constraints are corrected for the sake of consumer satisfaction. One of the public services is the clean water distribution system at Surabaya water enterprise. The water will be distributed as per the postpaid-metered or prepaid-metered recording user's clean water consumption. Exisitng postpaid-metered or prepaid-metered device in every househould must be checked by field officers regularly. This manual checking often causing problems of human errors. This study applied the Internet of Things (IoT) concept in automatic checking of postpaid-metered and prepaid-metered device in households. The customized and automatic clean water consumption recording device is built using the ESP32 module. The ESP32 will send the rest of the water consumption data to the server (cloud). This method is expected to automate solution and to create better services to the customers. The accuracy of the test results holds error tolerance value of 10.6%, in the test results with units of mL. The device is believed to be able to provide and alternative in water usage recording purpose.

Abstract

Various innovations have been developed in various sectors in industry, especially in the field of technology, one of which is the IoT (Internet of things) technology. The working principle of IOT is to control and monitor object equipped with sensors and connected to network that can later send data and even be able to communicate with other objects. One example is built prototype IOT-based refrigerator. The purpose of this study is to control the use of food ingredients (in the form of eggs and yakult) remotely. During this time users such as egg shops and yakult only receive the results sales and purchases of goods that have been made by employees, often the results of reports that are made are not in accordance with reality in the field. With these problems the authors make design of  controller using the refrigerator (eggs and yakult) using the ESP8266 microcontroller, DHT11 to measure temperature, Limit Switch is used for the process of opening and closing the valve. From the results of this research, the results are able to provide information to users in real-time, where users can find out how many items (eggs and yakult) are available in the refrigerator through an application.
