ABSTRACT
In this modern era, automatic plant sprinklers are important for important plants, coupled with the busyness of plant owners in caring for plants, watering plants manually is not practical, because homeowners have to come to the garden and water the plants directly using energy. The owner also cannot leave the plant for a long period of time, because the plant can lack water and cause the plant to wither or even die. Currently, the ease and efficiency of time and energy are the main considerations for humans in carrying out activities. From time to time we are faced with rapid technological developments, making human work easier. Therefore, this tool is designed to use a soil moisture sensor (soil moisture sensor) as a detector of soil conditions on plants by means of sensors detecting wet or dry soil and when the soil is wet the pump is ON to automatically water the plants. Plant owners can also monitor plants with LCD (Liquid Crystal Display) and blynk to know soil moisture conditions and their status through plants. This of course can make plant owners more effective in saving energy and time in caring for plants.

1. INTRODUCTION
Okra is a type of plant that does not require a lot of water, and is not resistant to standing water and drought, so it is necessary to have proper water distribution techniques for okra cultivation. If the plant lacks water, the plant is easily stressed, stunted growth, small fruit size, yellowing leaves, and can cause the plant to die.
Meanwhile, if the plant has excess water, it can lead to the appearance of fungi that attack the underside of the plant causing the roots to rot. In addition, if the water stagnates, the soil will become denser, resulting in disturbed oxygen circulation in the soil. (Rahayu, 2019).
Plant owners or farmers in Ikahi Raya plantations usually do watering manually by providing water according to a schedule. However, this method is less effective, because it requires a lot of time and effort and manually, humans often forget to care for and water the plants. The owner also cannot leave the plant for a long period of time, because the plant can lack water and cause the plant to wither or even die. Currently, the ease and efficiency of time and energy are the main considerations for humans in carrying out activities. From time to time we are faced with rapid technological developments, making human work easier. Therefore, the author tries to make a monitoring tool for soil moisture and plant watering automatically. Where in this tool the author uses a soil moisture sensor and Arduino Uno as the main control and control in the tool.

This soil moisture monitoring tool is made to function to water okra plants automatically using a soil moisture sensor (Soil Moisture Sensor), this tool is also equipped with an LCD (Linquid Cristal Display) which can display soil conditions according to the detection from the soil moisture sensor (Soil Moisture Sensor). This tool is also equipped with a water pump for draining water on okra plants, this tool is very useful for humans today, because with this tool humans no longer need to water the okra plants manually every day, for that this tool can be applied to humans who like to plant okra in their little garden.
With this background, a soil moisture monitoring device and automatic sprinklers will be designed on okra plants using a soil moisture sensor (Soil Moisture Sensor) then processed by Arduino Uno to detect soil conditions, if the range value is 0 - 69% wet soil status then pump and the relay will turn off but if the rage value is 70 - 100% dry soil status then the relay and pump will turn on until the soil moisture sensor (Soil Moisture Sensor) detects the soil is wet and the humidity status will be displayed on the LCD then the information will be sent via Sim800L and can be viewed through the Blynk application.
2. RESEARCH METHOD
Data collection is carried out to obtain maximum accurate and valid results. The data collection methods used in the manufacture of this tool are Arduino Uno, Soil Moisture Sensor, Power Supply, GSM Sim800L Module, Relay Module, DC Pump, 20 x 4 LCD. The author observes that plant watering activities are still done manually. How will the watering of these plants be done automatically by utilizing technology which will later watering the plants can be done automatically using soil moisture monitoring tools and automatic sprinklers.
Before designing a system or tool, the system is first planned based on the block diagram to the overall system circuit schematic. The block diagram shows the relationship of one or more components that have their own unit of work. In the block diagram of this system there are several blocks, namely the input block, the process block, and the output block. The block diagram as a whole as shown in the picture :

3. RESULTS AND ANALYSIS
From the design that has been done, it is obtained a soil moisture monitoring device and an automatic sprinkler using a soil moisture sensor (soil moisture sensor) on okra plants. Where the system unit consists of Arduino Uno as a microcontroller, soil moisture sensor (soil moisture sensor), power supply, pump, relay module, LCD, stepdown module XL4015, Sim800L. The following is a picture of the display component of the soil moisture monitoring tool and automatic sprinkler.

Figure 2. Implementing Tools in the Field
Testing water needs to find out how much water is needed for plants.
Table 1 Water Demand Test Results
Test Soil Moisture Pump Activity
100ml 85% Dry 5 Seconds
200ml 74% Dry 9 Seconds
300ml 61% Wet 12 Seconds
500ml 48% Wet 18 Seconds
In table 1 it can be seen the results of the water demand test, where when doused with 100 ml of water, the humidity is still at 85% indicating the soil is still dry and the pump activity flows water with 100 ml of water, which is 5 seconds. At 200ml of water the humidity is at 74% which indicates that the water is still not enough to wet the soil and the pump activity flows 200ml of water which is 9 seconds. Then at 300ml of water, the humidity has been at 61% where the soil has detected wet and the pump activity flows 300ml of water which is 12 seconds. And at 500ml of water, the humidity has been at 48% and the soil has been wet, the pump activity flowing 500ml of water is 18 seconds. From the results of these tests, it can be concluded that the need for sufficient water to wet the soil in 5kg polybags is 500ml of water with a pump activity duration of 18 seconds.
At 500ml water is good enough to wet the soil on okra plants
4. CONCLUSION
This soil moisture monitoring tool and automatic sprinkler can make it easier for garden owners to take care of plants. This tool can make it easier for garden owners to monitor the watering of their plants. This tool helps garden owners in saving energy and time in caring for plants. Through this tool, garden owners do not need to come to the garden to water the plants because watering has been done automatically. The pump used can also help plant owners to drain plant water.
