Abstract

The efforts to increase capacity while maintaining the granulation of the grinding process are carried out to maximize the use of the hammer mill machine, which is the second largest electric energy consumption in a plant. The method that can be done to achieve this is by setting the screen position and setting the right blower opening. Standard screen specifications will maximize the capacity of the grinding process and produce optimum granulation. In order to get the maximum grinding capacity, DFCO can be set at the maximum but will have an effect on the motor current during the grinding process, the average current will tend to be high. The aim of this research was to determine the effect of variations in the screen’s and blower’s position settings on the capacity and granulation of raw materials from the grinding process. The usage of 2.5 mm and 3 mm diameters screens, as well as adjusting the screen position of 2.5 mm at the top and 3 mm at the bottom, resulted in better capacity and granulation than using a screen with only 3 mm diameter. The larger the blower and DFCO openings, the greater the grinding capacity, but also increased the motor current. The larger the blower opening, the greater the decrease in the water content of grinding raw materials.

Abstract

The braking process is the basis in the making of the PWM speed control system in order for electric cars to be able to stop automatically and increase the driving safety. The usage of an electric motor as a wheel drive for an electric car allows controlling with a microcontroller. Based on the journal about electric motor control, it is necessary to study the use of PWM as a speed controller. The C language as a coding language can be understood by the Arduino microcontroller with the aim of regulating the speed of the electric motor. The research objective was to use the C language programming as a PWM speed controller with the Arduino microcontroller. The methodology used in this study was to modify a remote control car (RC) made as a prototype electric car. The Arduino microcontroller system was installed and programmed in C language as a PWM speed controller. The main sensor tool used was the ultrasonic distance sensor as the microcontroller input data. Direct current (DC) motors on RC cars were regulated with a pulse width modulation (PWM) signal as the output from the Arduino. LCD and buzzer were used as display devices and indicators of safe distances between prototypes and obstructions. The test results showed that the detection distance of the ultrasonic sensor reached 2 cm to 500 meters. Then the acceleration data obtained by pulse width modulation 64 at 1 meter distance, 127 at 3 meter distance, 191 at 4 meter distance, 225 at 5 meter distance and was made in graphic form. In a speed control system, the usage of the Arduino UNO microcontroller was easy to apply and had complete features. The series of speed control systems could be applied to electric cars with the PWM slow reduction criteria in two stages. The PWM lowering process took 1 second after the sensor detects an obstruction object.

Abstract

Pump units with a Caterpillar C27 engine with an EUI (Electronic Unit Injector) fuel system that often has low power due to filter clogging at PT. Sapta Indra Sejati. Filter cloggingoccurs due to due to the thickened biofuel content and creates a crust. If the machine has a problem, the mining process can be disrupted because the coal loading area is flooded. This study aims to create an additional system in the form of a automatic semi-returnless where the fuel return line is changed automatically into the filter because the fuel return is clean. The movement of the return control valve is regulated by a microcontroller which is programmed according to specifications and needs. The microcontroller used is Arduino Unowith pressure and temperature sensors. Arduino Uno is programmed when the engine will experience low power with a fuel pressure of 400 kPa then the return path is changed to semi returnless. With a change in the semi returnless path, the pressure becomes stable at 380 kPa and the engine RPM is stable with power that is still maintained. The advantages of semi-returnless system are that filter replacement costs can be reduced and production time is not interrupted.
