Abstract

With the increase in temperature that causes the life of the induction motor to decrease and often occurs in induction motors is the unbalanced phase voltage which causes the performance of the induction motor to decrease. in this paper describes the effect of unbalanced voltage on the temperature of a three phase induction motor, which is expected to be used as a reference for isolation and protection of the induction motor itself. The induction motor in an unbalanced voltage state has a higher temperature increase than the state of the five-phase induction motor in a balanced voltage, which is 0.36 0C / m for balanced voltage, 0.72 0C / m for 1% unbalanced voltage and 0.84 0C / m for 3% unbalanced voltage based on infrared thermometer measurements. While measurements using resistance measurements are 0.64 0C/m for balanced voltage, 0.934 0C/m for 1% unbalanced voltage and 1.147 0C/m for 3% unbalanced voltage.

Abstract

A Microstrip antenna is an antenna that has advantages in physical form, namely an antenna with a small shape so that it is easy to integrate. In addition to the small form of this antenna, it also has disadvantages such as narrow bandwidth and low gain. One of the solutions is that microstrip antennas can be designed using array techniques. The array technique in the design of the microstrip antenna is designed for the frequency of 850 MHz. This frequency is commonly used by communications service providers for LTE purposes. The material used is PCB epoxy (FR4) double layer with a thickness of 1.3 mm and a dielectric constant of 4.7. The shape of the patch made is a rectangle and a circle. The microstrip antenna was tested to obtain the value of the resonant frequency, VSWR and radiation pattern which then the results were compared with the simulation results using the IE3D microstrip simulator software. In the test, the results were obtained for a rectangular microstrip array antenna.

This study aims to design and implement a prepaid electricity top-up system that uses DTMF technology as an input method. The research methodology includes hardware and software design consisting of several main components, namely a DTMF module, microcontroller, and communication module. The DTMF module is used to detect and convert dual tone signals from the telephone into digital data that can be processed by the microcontroller. The microcontroller then processes this data to control the prepaid electricity meter top-up process. The system development stage begins with the selection and configuration of the appropriate DTMF module, followed by microcontroller programming to identify the DTMF code sent by the user. The system also includes a verification mechanism to ensure that the code entered is valid and secure. After verification, the microcontroller sends a command to the prepaid electricity meter to top up the credit according to the amount entered. The test results show that the DTMF-based prepaid electricity top-up system functions well, is able to recognize DTMF codes with high accuracy, and performs top-ups efficiently. This system offers ease of use for prepaid electricity customers, eliminates the need to go to a physical credit sales location, and allows top-ups from anywhere using a telephone. The conclusion of this study is that the DTMF-based prepaid electricity top-up system is a reliable and effective solution to improve convenience and efficiency for prepaid electricity users.

Abstract

Lead-acid batteries (batteries) are one of the most widely used resource components. Starting from small capacity for motorbikes, uninterruptible power supplies (UPS), up to hundreds of amperes for industrial use. When used, this battery needs to be recharged after use to obtain a stable voltage and current. In the charging process there are many ways that can be done, from rectifiers without filters, using filters to automatic ones (can detect the battery voltage level and turn itself off if the battery is fully charged). Automatic Battery Charger (ABC) is an electronic device designed to charge batteries automatically with high efficiency. One of the key components in ABC is the thyristor, a power control semiconductor that allows fast and safe battery charging. This research aims to design and implement ABC using a thyristor as a switch to control battery charging current. The methods used in this research include analyzing system requirements, designing electronic circuit schemes, selecting appropriate components, making and testing prototypes, and evaluating system performance. The designed ABC has features such as battery voltage detection to stop charging when the battery reaches full level, protection against overcurrent, and an LED indicator to display charging status. Test results show that ABC with thyristors can charge batteries with high efficiency and safely. The system is able to charge the battery quickly without producing excess heat which can damage the battery. In addition, this ABC is also equipped with security features that ensure safe and reliable operation. This research contributes to the development of more efficient and environmentally friendly battery charging technology. Implementing ABC with a thyristor as a battery charging current control switch can be an effective and energy-saving solution for automatic battery charging.

Abstract

Solar Power Plant (PLTS) is a more environmentally friendly generator, because this generator requires sunlight to be able to produce electrical energy. This PLTS is OFF-GRID so an energy storage place such as a battery is needed. The battery is also used to distribute electrical energy to the load where the load used is charging smartphones. And requires a solar charger controller that functions to regulate the electrical energy produced by the solar panel. This study analyzes the design of a smartphone charging station system as a public facility. In this test, 3 tests were carried out, namely testing how long it takes the battery to charge using solar panels, how long it takes the battery to discharge using a load, namely charging a smartphone, and conducting real-time testing by charging and discharging the battery together. The battery used has a total capacity of 12V 60Ah. In the battery charger testing method with a 100 WP solar panel, it takes 4 days, for the discharger testing using a load, it takes 6 days, and real-time testing shows that the output current fluctuates because the output current is very dependent on the intensity of sunlight that occurs when the solar panel charges the battery.

Abstract

In this study, a mini control timer system was analyzed in PDAM water treatment using the Control Wave method. In a water treatment system, timely control is very important to ensure optimal operational efficiency and water quality. The Control Wave method is applied to regulate and optimize the water treatment process more efficiently through automatic timer-based control. This system allows more flexible adjustments to variations in workload and operational conditions, thereby improving the overall performance of the water treatment process. which involves the development of a simulation model that describes the water treatment process with the integration of a Control Wave-based control system. The simulation results show that this method can improve energy efficiency, reduce downtime, and increase the stability of water treatment operations. In addition, the implementation of Control Wave in this mini control timer system has also been proven to be able to adjust to changes in operational needs dynamically, without sacrificing the quality of the processed water. The findings of this study provide a basis for further improvements in the control system in PDAM water treatment, especially in the use of automation technology to improve process reliability and efficiency.
