Abstract

At this time the 3-phase induction motors are needed in many areas including  small industries and in areas  having  only 1-phase electrical system. The area requires a motor  with a large driving force that can be operated with both normal and 1-phase  electrical system. An induction motor can work  ineither  normal  configuration  or modified configuration with  adding a series  of  capacitor motors in 3-phase induction motor. The series capacitors are used  with an auxiliary coil is placed on the side or sides of the coil which has a larger impedance. In this study,  the performance of 3-phase induction motors  is supported  with 1-phase electrical system coupled with the ACS758 current sensor . This coupling is  to measure the current value of the load being used. When the ACS758 current sensor detects  the passing current, it will display  the current value on the LCD which  facilitates  the user in the current value of the measured reading. Induction motor can work well and normal with 1-phase electrical system using a series of capacitor motors. Measurement with current sensor has an error less than 2%.Keywords: 3-phase induction motor, 1-phase electrical system, LCD

Abstract

Riccati differential equations have played important roles in the theory and practice of control systems engineering. Our goal in this paper is to propose a new multistage successive approximation method for solving Riccati differential equations. The multistage successive approximation method is derived from an existing piecewise variational iteration method for solving Riccati differential equations. The multistage successive approximation method is simpler in terms of computing implementation in comparison with the existing piecewise variational iteration method. Computational tests show that the order of accuracy of the multistage successive approximation method can be made higher by simply taking more number of successive iterations in the multistage evolution. Furthermore, taking small size of each subinterval and taking large number of iterations in the multistage evolution lead that our proposed method produces small error and becomes high order accurate.

Abstract

The habit of cleaning hands is one of the new habits during the current COVID-19 pandemic. One way to clean hands is with a hand sanitizer. The automatic hand sanitizer dispenser can be used to clean hands, without touching a button or any part of the appliance. Community service in this paper is carried out by making a number of automatic hand sanitizer dispensers, and distributing them in a number of places, around Campus III of Sanata Dharma University, Paingan, Maguwoharjo, Yogyakarta. A number of complaints emerged from the person in charge of the distribution site for the appliance. The most common complaint is that the appliance does not function as it should. This complaint is caused by a problem with the proximity sensor used. This sensor is too affected by light intensity. To overcome this, it is necessary to explore other types of sensors that are better than proximity sensors, which are less affected by light intensity.

Abstract

Vortex generators are addition surface that can increase heat transfer area and change the fluid flow characteristics of the working fluid to increase heat transfer coefficient. The use of vortex generators produces longitudinal vortices that can increase the heat transfer performance because of the low pressure behind vortex generators. This investigation used delta winglet vortex generator that was combined with rectangular vortex generator to Reynold numbers ranging 6,000 to 10,000. The parameters of Nusselt number, friction factor, velocity vector and temperature distribution will be evaluated.

Abstract

One source of renewable energy is solar energy. The main component in a solar energy system is the solar panel. To maximize the amount of sunlight harvested by the solar panels, the panels need to track the position of the sun. In this study, a dual-axis tracker is used in the form of a tip-tilt dual-axis tracker. The drivers used are two DC motors equipped with a gear box. The algorithm used is an LDR sensor output based algorithm. Solar panels equipped with solar trackers, even with a simple algorithm using LDR output values, can improve the performance of solar panels. The current generated by a solar panel with a solar tracker is higher than when the solar panel is in a static position. The current difference in the two conditions is the smallest of 16.17 mA and the largest of 544.01 mA. When using a solar tracker, the output power of the solar panel is more than 5.32 W, while when it is fixed, the power of the solar panel is small, even reaching 0.25 W. The output voltage of the solar panel is more than 13 V, while when it is fixed, the voltage of the solar panel is drops to below 13 V, which is 12.81 V.

Abstract

Increasing waste production worldwide has become a serious environmental and social problem. Waste thrown into traditional landfills can pollute land and water, cause public health problems, and produce greenhouse gas emissions.  To overcome the issues above, in this research, a waste sorting machine will be designed that can sort organic and inorganic waste. This sorting is done automatically, a person only needs to put the waste into the machine, and then the waste will be separated according to its category.  The organic and inorganic waste sorting system consists of 5 sub-systems.  They are metal waste, glass waste, dry waste, plastic waste, and wet waste sorting.  The results of this study can produce a success rate of 66.7% in detecting the occupancy of the trash bin, 70% in sorting metal waste, and 44.4% in sorting glass waste.  The success rate in sorting wet waste is 40%, while in sorting plastic waste is 70%, and in dry waste is 90%.
