Abstract
Water in the reservoir on the first floor is often empty, resulting in no running water for each toilet in the Information Technology. In addition, the water pump in the Information Technology is still turned on manually, so the officer must occasionally control the water pump. The method to be used in this study is the Software Development Life Cycle (SDLC) Waterfall model. The hardware used is NodeMCU ESP8266, HCS-R04 which functions to measure water level and water volume, relay, and YF-B10 which functions to measure water discharge and volume. The results obtained were that the water level measured using the HCS-R04 was 11 cm high, while the water level was 10.7 cm measured using a meter. The water discharge obtained is 6 L/m. The water pump status feature, and the ON/OFF feature on the Android application are declared successful for turning on and turning off the water pump.

Technological advances have recently increased very rapidly in various fields, many technologies have facilitated and assisted human work efficiently and effectively. There are tools created with IoT (Internet of Things) which are tools that can be connected to the internet, so that the tools that are made can communicate with each other via mobile devices, or PCs [1].
Water is an important thing in human life, water is usually taken from wells or from reservoirs that already contain water [2]. The tool that is usually used to drain water is a water pump. A water pump is a tool for sucking water from a well into a water tank, or from a water tank to another water tank. In the IT study program the water pump is used to raise water from the tank on the first floor to the water tank on the fifth floor. However, the water in the water tank on the first floor is often empty, when the water pump is turned on, the water pump that should suck up water actually sucks up the wind, resulting in the water pump breaking down quickly, wasting electricity, and there are no toilets in IT study programs flowing water. In addition, the water pump in the IT study program is still turned on manually, so the officer must occasionally control the water pump.
As a way to streamline time and make it easier for officers to monitor the water pumps and reservoirs in IT study programs, a device is needed to find out the volume of water in the reservoirs. Therefore, a tool was created using the Internet of Things to carry out controlling and
monitoring in real time connected to a mobile application, on water pumps and storage tanks. The results of making this tool are expected to save time, make it easier for officers, minimize damage to water pumps, reduce electricity bills, and each toilet has running water.
Software Development Life Cycle (SDLC) method with Waterfall model is the method used in this research. The Waterfall model defines a number of sequential stages, so they must be completed step by step and move on to the next stage when the previous stage has been completed. The Waterfall model is recursive where each step can be repeated indefinitely until it is perfect [3]. Figures from the stages of the Waterfall model can be seen in the figure below.
Figure 1. Waterfall Model
Figure 1 is the Waterfall model SDLC method. The Waterfall model is used because each stage can be repeated endlessly until the stage is completed. The stages in the waterfall model are analysis, design, implementation, testing and maintenance [4]. This study uses the Internet of Things to monitor water pumps in real time connected to a mobile application. The following is an overview of designing Internet of Things (IoT) tools.
Figure 2. IT Study Program Water Pump Topology
To find out the volume of water in the first floor reservoir, an ultrasonic sensor is needed to determine the volume of water. In addition, there is a water flow sensor to determine the water discharge, and a relay to turn on the water pump. All existing sensors will be
connected to the NodeMCU microcontroller. NodeMCU will process all the data provided by the sensor, and send data to the internet which is received by the smartphone. So the water pump will start when the water tank on the first floor contains water, while the water pump will stop when the water tank on the first floor doesn't contain water.
The theoretical basis compiled to be able to solve existing problems include the following.
The Internet of Things (IoT) is hardware that can communicate between devices over the internet using a microcontroller. Internet of Things is commonly used on refrigerators, TVs, air conditioners, and others that can be controlled using a smartphone or the web to turn off or on devices [5].
NodeMCU ESP8266 is a microcontroller based on the ESP8266 chip that can accept input and output from hardware and software, so it can connect to the Internet [6]. The NodeMCU ESP8266 module has the same function as Arduino, but the difference is that the NodeMCU ESP8266 has an ESP8266 chip or WiFi which makes it easy to connect to the internet.
HCS-R04 is a type of ultrasonic sensor that can be used to measure the distance from an object. The HCS-R04 can emit full wave with a frequency of 40000 Hz, when the wave hits an object it will be reflected again to the HCS-R04 ultrasonic sensor, the distance that can be measured is around 2 cm to 450 cm[7]. This device uses two digital pins to determine the distance obtained, and GND, VCC pins to provide electrical power.
Relay is an electrical component that has two parts, coils and points. The function of the relay is to control and transmit electricity, the relay is used to be a switch. The switch in question is like a switch in general but the relay works at a low electric current, when the relay receives a low electric current the relay can be used to cut off the flowing electric current [8].
Water flow sensor is a sensor that is used to measure the discharge of fluid flowing in the pipe. The water flow sensor consists of a water rotor and a half effect sensor and there is a valve body (plastic valve). The way the water flow sensor works is when the fluid passes through the sensor, the half effect sensor will detect the rotor rotation on the water flow sensor. The rotation generated by the rotor will generate a digital pulse that is proportional to the amount of fluid entering through the water flow sensor [9].
Arduino software is an opensource platform used to write programs that will be included in a microcontroller. The types of microcontrollers are Arduino, NodeMCU ESP8266, ESP 32CAM, and so on. The language used in the Arduino software is C++ which has been simplified through the library, so it is very easy to use for beginners who don't have a basic programming language. [10].
Android is an operating system that Android developers can view and modify and use to manage hardware resources such as smartphones and tablets, as well as an open source Linux-based operating system. The Android operating system is distributed under the Apache Software License (ASL/apache2), which allows for second distribution and so on [11].
Realization of the design results of the hardware design as well as testing of the water pump controlling and monitoring system is carried out by conducting experiments to send and receive data from Android applications and from Internet of Things (IoT) tools.
