Fuel oil reservoir filling and temperature monitoring can be done automatically using Omron PLC type CP1E N20DR-D 20 I / O with a ladder diagram program designed with the CX-Programmer computer application. And the input used in the form of a level sensor module and temperature sensor, while for the output in the form of a selenoid valve, 3 phase AC motor and buzzer. The level sensor functions to find out the high and low levels of the oil surface in the tank and the output is in the form of a selenoid valve module that functions as a valve for filling full oil, while the motor pump functions as a distributor fuell oil. And the temperature sensor module serves to detect the high and low temperatures or safe temperatures that are allowed at the time of distribution of fuel to the Truck fuel oil reservoir, while the output is in the form of a buzzer that serves as a source of sound or alarm markers. Based on the calculation results obtained that the error presentation of the two selenoid has the same value of 0%, while the level sensor, thermal sensor, and pump motor each have a presentation value that is almost the same with each other, so that the automatic control system of filling the fuel oil reservoir and monitorn the temperature can run smoothly.

Over Time

Freshwater supplies on people's ships are a vital need that must be met during the ship's voyage. The distribution system used without control will be troublesome for the Crew, who are always in charge of controlling the availability of water in the daily tank and running the water pump. Water pump control equipment is used to help reduce the working time of the Crew and can improve the performance efficiency of the water pump. A buoy switch is a control tool that is often used, but the buoy system will be disrupted over time. An automatic control system using a water level sensor is not familiar to use to control the water pump. From the design results of this system is more efficient than the buoy switch. Its efficiency can be seen from the degree of sensitivity to changes in water level, as well as longer service life. This system can be used to control the work of water pumps without supervision or control of the Crew, thus saving more time and the availability of water in the daily tank remains available at all times.

Abstract- The stove is one of the main tools used in households. Used to heat an object in the form of food. In its development, the stove used for cooking has experienced many advances, one of which is an electric stove. Currently electric stoves on the market, especially the electric stove, halogen heater, single ceramic stove, are available in the form of a rotary switch on / off. The purpose of writing this scientific research is to design an automatic control system on this single ceramic stove type halogen electric stove. Where previously stove control using only a rotary switch was changed to automatic control via a keypad in the form of a timer and temperature input with a digital display via LCD. The electrical components used are the Arduino Mega 2560 microcontroller as the control center, MAX6675 as a temperature sensor, ACS712 sensor to read current values, ZMPT101B sensor to read voltage values, relay as electric switch, buzzer as alarm, keypad as input and LCD as display output on electric stove. The results of this design were obtained in accordance with what was the goal of this scientific research where previously the electric stove was manually controlled to be converted into automatic control by inputting the required temperature value and working based on the temperature setpoint input and displaying the amount of energy released on the electric stove. Keywords— Arduino Mega 2560 Microcontroller, MAX6675, LCD, Keypad, Halogen Electric Stove.

Abstract In this paper, an intelligent water dispenser automatic control system is designed by using a microcontroller as the core. Relevant signals are collected through temperature sensor, liquid level sensor and other sensors, then send them to the microcontroller for processing and control, and use the liquid crystal display for display. Temperature, effluent and liquid level can be controlled according to their own needs, so as to realize the intelligent control of the water dispenser. The intelligent water dispenser automatic control system designed in this paper has low hardware cost and easy operation in the use process.

The roller and sieve machines most commonly used in Russia for the post-harvest processing of root and tuber crops and onions have a number of disadvantages, the main one being a decrease in the quality of sorting due to the contamination of working bodies, which increases the quantity of losses during sorting and storage. To obtain high-quality competitive production, it is necessary to combine a number of technological operations during the sorting process, such as dividing the material into classes and fractions by quality and size, as well as identifying and removing damaged products. In order to improve the quality of sorting of root tubers and onions by size, it is necessary to ensure the development of an automatic control system for operating and technological parameters, the use of which will eliminate manual sorting on bulkhead tables in post-harvest processing. To fulfill these conditions, the developed automatic control system must have the ability to identify the material on the sorting surface, taking into account external damage and ensuring the automatic removal of impurities. In this study, the highest sorting accuracy of tubers (of more than 91%) was achieved with a forward speed of 1.2 m/s for the conveyor of the sorting table, with damage to 2.2% of the tubers, which meets the agrotechnical requirements for post-harvest processing. This feature distinguishes the developed device from similar ones.
