PENERAPAN SENSOR CJMCU101 UNTUK MENDUKUNG SISTEM SMART LECTURE ROOM

This study presents the design of a Smart Lecture Room system that utilizes light intensity sensors, specifically CJMCU101. These sensors are installed in each classroom to monitor the ambient conditions. The implementation of the designed system was carried out in the classrooms of the Udayana University Electrical Engineering Study Program. To achieve this goal, the classroom utilized by the Electrical Engineering Study Program of Udayana University was divided into two classes (DH101 and DH102) and a sensor was installed in each class as an IoT device. The IoT devices are connected to a Raspberry Pi Access Point, where the data from the sensors is stored and monitored using the Thinger.io platform. The validation of the sensor testing is carried out by comparing the results obtained from the sensors with the results obtained from a thermohygrometer measurement. This research produces a prototype smart lecture system, applied to a classroom mockup, that employs IoT devices, sensor databases, and sensor monitoring. The data from each sensor's detection is stored in the LAMP database, which employs Linux, Apache, MySQL, and PHP. The Thinger.io platform monitors the values of each sensor. A variation in accuracy between the sensor and measuring instrument results in a difference in their values. The CJMCU101 light intensity sensor has an average accuracy of 93.48% compared to the measuring instrument on DH101. The average accuracy of the sensor value compared to the measuring instrument on DH102 is 95.96%.

Analisis Audit Energi di Gedung Teknik Elektro Universitas Diponegoro

An energy audit is a work that aims to identify energy consumption in buildings that have been built so that they can find opportunities for energy savings in these buildings and buildings and improve energy efficiency and conservation in these buildings. The Electrical Engineering Building is one of the buildings at Diponegoro University that has been built for a long time, and to find out the savings opportunities in the building, an energy audit is needed. The energy audit was carried out during the pandemic era where lectures were still being held online and hybrid. Based on the results of the energy audit that has been carried out, it was found that the Energy Consumption Intensity (IKE) in the Electrical Engineering Building in 2021 was 8.59 while in 2022 it was 12.61. This is still in the efficient category according to Regulation of the Minister of energy and mineral resources No. 13/2012. Opportunities for savings can be implemented starting from no cost, low cost, to high cost to increase the efficiency of energy use in the Diponegoro University Electrical Engineering Building, so that energy use can be very efficient.

Active Gate Driver for Dynamic Current Balancing of Parallel-Connected SiC MOSFETs

In high-power applications, parallel connection of discrete silicon carbide (SiC) MOSFETs is necessary to increase the current rating. However, the unbalanced dynamic current during switching transient may cause unequal power loss and thermal distribution, which is a great challenge in parallel applications. In this paper, a dynamic current balancing method based on a new active gate driver (AGD) is proposed to improve the current sharing. The principle of the AGD is based on <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">di/dt</i> feedback control and voltage controlled current source to adjust gate drive current of SiC MOSFETs. Therefore, the switching trajectory of the paralleled devices can be changed to achieve current balance. In addition, by using master-slave control strategy, the proposed AGD can be easily used for multiple paralleled devices. The double pulse tests are conducted to verify the effectiveness of the proposed AGD. For two paralleled devices, the turn-on and turn-off switching energy imbalances are reduced from 13.4% and 56.0% (12.1% and 52.9%) to 8.8% and 15.3% (8.0% and 8.8%) by the current source (current sink) circuit. For six paralleled devices, the degrees of turn-on and turn-off switching energy imbalances can be reduced from 21.8% and 16.1% to 11.8% and 7.8% by the proposed AGD. <fn fn-type="other" id="fn3" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This work was supported by Key-Area Research and Development Program of Guangdong Province under Grant 2021B0101310004, and the research program sponsored by Eaton.

Relationships Among Economy, Industry, Vocational Education and Training and Higher Engineering Education – The Trefort Project Editorial

It is a great pleasure to contribute some words to the debate about Engineering Education as well as to broaden the discussion about the future evolution of this discipline. Thanks to the International Journal of Engineering Pedagogy (iJEP) and its editor-in-chief, Matthias Utesch, as well as to the collaboration between the IGIP (International Society for Engineering Pedagogy), we have received a possibility to collect the best papers of our 9th Trefort Ágoston Conference on Vocational Education and Training and Technical Teacher Training at Óbuda University (ÓE) Electrical Engineering Faculty in Budapest, in Hungary. The Conference was organized as an IGIP Regional Conference for the third time. Before introducing the articles, I summarize the main important elements influencing the Higher Engineering Education in Hungary. The Fourth Industrial Revolution unfolds, companies are seeking to harness new and emerging technologies to reach higher levels of efficiency of production and consumption, expand into new markets, and compete on new products for a global consumer base composed increasingly of digital natives. There are several requirements for qualified engineers: they have to be creative, critical thinking, complex program solvers and have to have competencies of cognitive flexibility, high-level communication, teamwork, and application of foreign languages. At our university, we have recognized several problems according to SWOT analyses. Not enough number of students would like to select STEM faculties. The rate of early school leaving (ESL) is too high in the STEM area. Requests of the Labor market have not appeared in Training curricula. The candidate students do not know the future carrier and the content they have to learn. In secondary schools, the development of basic competencies and STEM subjects is not effective e.g. teaching Math is not practice-oriented, this is why the results of students on PISA tests are weaker. The preparation for higher education is not enough, which leads to ESL by the end of the first year in higher education. The quality of knowledge of secondary education pupils is an important input for engineering higher education. The vocational secondary schools can provide the majority of starting engineering studies at technical universities. The technical teacher training prepares the vocational teachers for secondary vocational schools. The quality of technical teacher training, the adequacy of curricula to professional needs can be key questions for the future of engineering education. The practice of vocational teacher-students is a basic element of their studies. These practices are organized in secondary vocational schools. But realizing these practices needs a mentor teacher. In this Trefort Project, we selected 6 presentations and asked the authors to submit their articles for a Special Issue of the International Journal of Engineering Pedagogy (iJEP).

Impact of admission grade point average on academic results of university students in electrical engineering

This work analyzes the impact of admission grade point average (AGPA) on academic results of electrical engineering university students throughout their undergraduate studies. The analysis was carried out on two bachelor engineering degree programs offered at the School of Telecommunication Engineering at the Universidad Politécnica de Cartagena, Spain: Telecommunication Systems Engineering and Telematics Engineering. Data from seven consecutive academic years were used to compute three indicators regarding the same cohort of students: exam attendance rate, success rate, and performance rate. The results show that although there exists a significant correlation between AGPA and student performance, it is truly relevant only in the first two academic courses (in this work, a course is assumed to be the compilation of all subjects in a year). In view of the results, a set of guidelines is proposed in order to soften the impact of AGPA on the progress of university students.

SAIL—Software system for learning AI algorithms

AbstractArtificial intelligence (AI) comprises a large spectrum of groups of algorithms: heuristic algorithms for search and planning, formal methods for representation of knowledge and reasoning, algorithms for machine learning and many more. Since these algorithms are complex, there is a need for a system which would enable their application both in everyday work and education processes. This paper describes a software system for learning AI algorithms called SAIL (Software System for AI Learning), which can be used both on computers and mobile devices. The paper gives examples of lab exercises and self‐study tasks that through graphic representation and detailed procedures help students master this area. Students can enter their examples into the system and obtain correct solutions for those examples. At any point when an example is simulated, a student can proceed to the next step or go back to the previous one, save the current simulation as a file, or print the detailed procedure as a task solution. SAIL helps lecturers go through the syllabus more efficiently and improve class material, while at the same time it helps students get a better grasp of implemented algorithms. SAIL can also benefit software engineers, who can select and simulate an adequate algorithm to solve a specific problem. The results of the SAIL system are verified within the AI introductory course at the School of Electrical Engineering University of Belgrade and they are presented in this paper.

Development of FPGA based power flow monitoring system in a microgrid

In recent decades, smart grid has become increasingly attractive to both energy producers and consumers. Amongst the main challenges for the successful realization of smart grid includes the integration of renewable energy resources, real time demand response and management of intermittent energy resources. Apart from smart grid, the development of micro-grids should take into consideration of issues such as the system performance, modelling, monitoring and controlling of the micro-grids. In particular, the recent advancements in information and communication technologies (ICTs) could facilitate the effective development of the future micro-grid system. The goal of the study is design of a system, based on FPGA, which monitors the power flow of the Microgrids. First of all a MG system installed in the laboratory of Firat University Electrical and Electronics Engineering Department consists of 1.2 kWp grid connected PV system, 5 kW micro hydro turbine, 0.5 kW wind turbine and 0.1 kW fuel cell unit was introduced. Afterwards, for smart-grids, a system of power flow that has a powerful high sampling rate was dwelt upon. During implementations, the data collected from the power system was transmitted to the FPGA cards located in open area by wireless data-monitoring card. This study has contributed to studies of other researchers by means of the monitoring system which has a high sampling frequency.

A Century of Development in Applied Electrostatics [History

This paper discussed the development and detailing history of applied electrostatics which give advantages and disadvantages. Most electrical engineers, the term electrostatics brings to mind some hazy visions of early electrical experimentation involving an ancient Greek, a dead cat, and a piece of amber. Many of us recreated this quaint demonstration of triboelectric charging and its subsequent attraction in high school physics class. Perhaps some, in more enlightened schools, substituted modern materials such as plastics and synthetic fibers. In university electrical engineering programs, electrostatics is usually ignored or relegated to mathematical simplifications involving quasi-electrostatic approximations of important applications in electromagnetics. Meanwhile, a serious work involves the state-of-the-art study of topics such as electrodynamics and digital electronics. These fields have dominated so many important advances in the 20th century.

Improvements to an Electrical Engineering Skill Audit Exam to Improve Student Mastery of Core EE Concepts

The San Jose State University Electrical Engineering (EE) Department implemented a skill audit exam for graduating seniors in 1999 with the purpose of assessing the teaching and the students' mastery of core concepts in EE. However, consistent low scores for the first years in which the test was administered suggested that students had little incentive in reviewing for passing the test. To promote the concept that there is a set of basic skills every graduating senior should master, improvements were implemented that included creating an online exam used for review and requiring students to earn a 70% or higher score on an in-class exam that is a requirement for graduation. After the improvements were made, all students demonstrated at least 70% mastery of the core EE concepts as measured by the improved in-class skill audit exam. The details of these improvements are presented. Anonymous survey results of graduating seniors indicate that students feel that preparing for the skill audit exam was a good use of their time and that the exam should be made more rigorous for future students.
