Abstract

Shallots are one of the leading commodities in several regions in Indonesia. In the cultivation of shallot plants there are pests that can reduce the quality of shallots. Along with the times, and to overcome the problem of watering pesticides for shallot plants, an automation tool is designed to make it easier for farmers to water pesticides. The design of this tool uses the concept of Internet of Thing (IoT) where the application used is Node-RED with the MQTT protocol. The optimum humidity for the growth and development of shallot plants is 50-70%, so soil moisture sensors are used to measure soil moisture. Pesticide watering also looks at weather conditions such as rain. Therefore, the raindrop sensor is used to detect rain. From several trials that have been carried out, it produces one experimental result that shows soil moisture of 35% where weather conditions are not raining and, the relay is active to perform pesticide watering. This indicates that the pesticide watering of shallot plants using the MQTT client-server network is successful carried out.

Abstract

The types of inputs and outputs of a control system that exist today are quite varied with their respective advantages and disadvantages that can be adapted to existing needs. So with the complexity of the system, the price is also very expensive. As one option to overcome this problem is to utilize Highway Addressable Remote Transducer (HART) data through the application of the HART Concentrator System (HCS). HART data has four variables, namely Primary Value (PV), Secondary Value (SV), Third Value (TV) and Fourth Value (FV). All this data can be sent simultaneously to HCS and collected. Then the data on the HCS will be sent via RS485 serial communication to the Modbus Gateway TCPIP. At this Modbus TCPIP gateway, Modbus data can be sent via an Ethernet network so that it can be accessed flexibly by SCADA.

Abstract

An underground tank is a type of tank installed by burying it on the ground. Underground tanks in the form of a storage area with large dimensions for either liquid or gas, especially BBM (fuel) which is stored underground at Public Fuel Filling Stations his (SPBU). The supply of liquid in this tank really needs to be maintained to meet the need for liquid. In order to be able to monitor the volume of liquid in the underground tank, a device was designed that can monitor the volume of liquid in the tank remotely. This device uses an ultrasonic sensor that can detect the volume of liquid that has been converted from the distance detected by the sensor, and uses Wemos D1 mini on the device and ESP32 on the server as a microcontroller that sends data from the reading process to smartphones and websites. The device works on ultrasonic sensor which can sense the distance and with some calculation it detects how much liquid is sensed as a volume and employs a Wemos D1 mini on the side of device and an ESP32 on the server part as a microcontroller that sends reading data to smartphones and websites. The smartphone displays show liquid volume and distance shown by the sensor while in the server display distance is plotted against time in graphical form. Test results reveal that this device can remotely detect underground tank liquid volume using smartphones or websites with a success rate of 72.35%. This failure rate of 27.65% is caused by curved tanksurface and misplacement of the tank.
