ARDUINO UNO BASED AUTOMATIC DESIGN TO BUILD WINE DRINKING TOOL USING SOIL MOISTURE SENSOR

The development in this era is increasing, humans expect a tool or technology that can help human work, because now technology has become a human need. Therefore, a device that can do watering the wine is made automatically. This tool aims to replace manual work to be automatic. The benefits that can be obtained from this tool is that it can facilitate human work in watering grapes. This tool uses a soil moisture sensor which functions as a soil moisture detector and sends commands to Arduino uno to turn on the relay driver so that the pump can flush water according to soil needs automatically. The making of this final project is done by designing, creating and implementing system components including Arduino uno as a controller, relay drivers for turning on and off the water pump, LCD (Liquid Cristal Display) to display soil moisture values. The results of the research prove that the tool made can function properly and can be developed as expected. The tool can water the vine when the soil humidity is below 50%, and turn off the pump when the soil moisture is above 50%.


INTRODUCTION
Some grape farmers in Indonesia still depend on the season for farming. This causes agricultural production to be unstable at any time. In the dry season the yields increase but the grape farmers have to water the vines manually and it is done every day. Meanwhile, during the rainy season the production of agricultural products decreases and even crops fail due to heavy rains. This is what causes many farmers to suffer losses and ultimately are disappointed with the yields of their crops. During the dry season the farmers have to spend energy and money to water the vines manually so that the plants can thrive and be able to harvest. Therefore, many consumers who are not satisfied with the results of grape farming during the rainy season, some of those who like to eat grapes choose to grow their own grapes. And seen from the daily activities of those who are busy in the office, there is very little time to water the vines. (Wicahyo. H. 2019) In the current era of globalization we cannot be separated from development and technology, therefore we must be able to master technology and compete with other countries. Currently, the ease and efficiency of time and energy are the main considerations for humans in carrying out activities from time to time. At this time humans are faced with rapid technological developments that make human work easier. Therefore the author tries to create an automatic wine sprinkler system, where in this tool the author uses a soil moisture sensor and Arduino Uno as the main control and control in this tool. Against this background it will be planned

System design
The design of this system is an innovation that is owned by the author for the development of an automatic wine sprinkler based on the Arduino Uno microcontroller using a soil moisture sensor. The goal of this research is to make it easier for us to water the grapes and find out how the soil moisture sensor works, where the sensor will read dry or humid soil conditions, then move the relay to turn on the

Results
The results of the system can be seen in Figure 4.1 which is the original image of the device that has been built. Where Arduino uno, relay, LCD, resistor, LED lamp, arranged in such a way in a black box with a size of P = 18 cm, L = 9 cm, T = 5 cm. Besides the black box there is a 12v Power Supply, terminal, water tank, pump, soil moisture sensor that is plugged into the vine.

Discussion
In this discussion, the author will discuss the results of testing the design of an automatic vine watering system using a soil moisture sensor and Arduino Uno. Based on the RH of the soil that has been set according to the needs of the vine, this tool is also equipped with an LCD (Liquid Crystal Display) which can display soil conditions whether moist or dry according to the reading from the soil moisture sensor in the form of a value on the LCD. This tool is also equipped with a water pump for watering wine, this tool is very useful for us at this time, because with this tool we no longer need to water the vines manually every day, for that this tool can be applied to everyone who likes plant grapes in front of the house or plant grapes in a small garden near the house and in other places that are closed, because this tool is not applied to the open.

CONCLUSION
Based on the test results, the Arduino Uno based automatic vine sprinkler system can be concluded as follows.
1) The system can water the vines when the soil humidity is below 50% RH. 2) The system cannot water the vines when soil moisture is above 50% RH. 3) For the vine the humidity must be brought from 80% RH for the vine to flourish.
