Abstract

Sun tracker is a system that developed to get the maximum energy of sun light while following the sun position. Most of the solar panels do not have this kind of technology to monitor the position that has the maximum voltage, thus a website application is made to monitor the voltage that is received by the sun tracker in realtime. Web socket technology is the solution to obtain information in real-time. Socket.io is the service that is used to fulfill this web socket technology in this development system. Socket.io is a web socket technology for websites that allows servers to process data in real time so that information on the angle position of the sun tracker and the voltage received by the solar panel can be sent to the website in real time. As a result, this monitoring system is able to move the solar panel in accordance with the direction of sunlight and display the angular position of the solar panel and graph of the voltage received by the solar panel directly (real-time) using socket.io.

Abstract

Augmented Reality technology applied in the world of education can make the learning process more effective and more efficient. This study built an augmented reality application by applying the marker based tracking method which was then applied to the industrial instrumentation practicum course at the Faculty of Agricultural Technology, Udayana University. This aims to make practicum more effective and efficient. The resulting application is then tested using 2 tests, namely usability testing using the Usability method with a Likert scale and comparison testing using the Paired Sample T-test method. Usability testing aims to determine an assessment of the usability level of the application. In this test, we get a reusability value of 73.5 from a scale of 0-100. These results can be interpreted that this application has a good usability value. Comparative testing using the Paired Sample T-test method aims to obtain information on the extent of the comparison of the understanding of each respondent before and after the application of augmented reality in industrial instrumentation courses. In this test, the Sig. (2-tailed) of 0,000 which is still below the threshold of the Paired Sample T-test, which is 0.05. So this research concludes that there is a real difference between the results before and after the respondents used the application. This study concludes that the functionality of using this application can be considered to replace the visit of industrial instrumentation practicum courses so that the implementation of practicum becomes more effective and efficient.

Abstract

The emergence of harmonics caused by electrical loads that are not linear. Input of harmonic current can cause sinusoidal. Content that exceeds the limit can cause poor power quality. The level of harmonic distortion or called Total Harmonic Distortion (THD) on the network causes losses and voltage drops, which affects the efficiency of the transmission network system. Harmonic attenuation is the right choice to reduce harmonic current (THDi). Based on the IEEE 519-1992 standard the expected harmonic current must be below 5%. In this study an active filter has been designed to be able to drain the harmonic current contained in the system using the 6 pulse converter on Statcom.

Abstract

Forecasting is the process of estimating a future value using data from the past or data from the present as a reference. Forecasting is a critical component of an organization's short- and long-term planning as a reference for management decision making. Identifying the data pattern in the time series data utilized is a crucial step in identifying the best forecasting approach for the data pattern. The Gray Prediction Model is a forecasting technique that can be used with partial data or a little amount of data. The Grey-Markov forecasting approach may be used to make very accurate forecasts using Udayana University education acceptance data, which is limited, with only five historical data and data patterns classed as horizontal data patterns with modest fluctuations.

Abstract

Multilevel inverter (MLI) is one type of inverter that has a multilevel output voltage. Although its better than conventional inverters, the MLIs operating at low frequency still contains low-order harmonics at the output voltage and current which have a negative impact on electrical system. To overcome these problems, Many researchers have developed various control and modulation techniques on inverters to reduce harmonics and minimize switching losses with the aim of optimizing inverter’s efficiency. Selective harmonic elimination pulse-width modulation (SHEPWM) is the most optimal control of all methods that have been developed to remove low-order harmonics from the inverter output voltage. However, there are challenges in the MLIs analysis process using SHEPWM because solving these equations is difficult. Bio-inspired intelligent algorithms (BIAs) is used to solve this problem. This paper describes in full a review of various studies that have been carried out previously related to the operating principle of nine types of BIA and their application in reducing harmonics. The conclusions has been made on the basis of information extracted from the literatures. All important information in this paper regarding harmonic reduction in MLI will help future research to design efficient power conversion systems. Keywords— Bio-inspired algorithm, harmonics, multilevel inverter, optimization, selective harmonic elimination.

Abstract

Buck-boost inverter is one tool that can convert Direct Current (DC) voltage into Alternating Current (AC) voltage while simultaneously increasing and decreasing the output voltage. On the other hand, there is a problem with induction motors, namely the presence of Common Mode Voltage (CMV) or the voltage between the neutral point of the motor and ground which can accelerate wear on the bearings and damage to the motor. One method that can reduce CMV is by using an active filter. Another problem due to the use of inverters is that there are harmonics due to the switching process. This research will examine the effect of adding modified BBI plus an active filter to a three-phase induction motor on CMV and THDv. This research process begins with designing a circuit simulation in the MATLAB application, then simulation testing is carried out to see its effect on CMV and THDv values. BBI simulation test results after the addition of active filters with conventional inverter circuit CMV worth 250V with THD worth 6744.45%, while the BBI circuit coupled with active filters worth 22V and THDv worth 114.53%. As well as the BBI circuit plus an active filter, CMV is worth 2.6V with THDv worth 65.30%.
