Abstract

This study aims to investigate (1) the availability of learning facilities for distance learning (or online learning), (2) the ability of students and teachers to utilize the learning facilities, and (3) how distance learning activities take place at public or private vocational high schools, specifically whether it is perceived to be more interesting than ordinary learning. This study used a survey method to obtain data and a quantitative descriptive method to analyze the data. The type of data in this study was primary based on the responses of respondents or individuals from groups representing the population of public and private vocational high schools, especially in the Electrical Engineering Clusters in the entire areas of West Java. The results revealed that online learning has been carried out in many public and private vocational high schools in West Java. This study indicates that the availability of online learning facilities, the utilization of facilities, and the online learning process in public vocational high schools were better than those in private vocational high schools. In general, students of both public and private vocational high schools stated that online learning is not more interesting than ordinary learning, although most of them can understand the lessons taught and they were given an opportunity by their teachers to actively participate during the learning process.

Abstract

This paper reports a compact design of electromagnetically driven MEMS micro-actuator utilizing planar electromagnetic coil on PCB (Printed Circuit Board). The micro-actuator device consists of an NdFeB permanent magnet, thin silicon membrane and planar micro-coil which fabricated using simple standard MEMS techniques with additional bonding step. Two planar coils designs including planar parallel and spiral coil structure with various coil geometry are chosen for the study. Analysis of the device involves the investigation of electromagnetic and mechanical properties using finite element analysis (FEA), the measurement of the membrane deflection and functionality test. The measurement results show that the thin silicon membrane is able to deform as much as 12.87 µm using planar spiral micro-coil. Reasonable match between simulation and measurement of about 82.5% has been revealed. The dynamic response test on actuator driven by parallel planar coil shows that silicon membrane effectively deformed in 40 s for an input electrical power of only 150 mW. It is also concluded that planar parallel coil is considered for the simple structure and easy fabrication of the actuator system. This study will provide important parameters for the development of compact and simple electromagnetic micro-actuator system for fluidic injection system in lab-on-chip.

Abstract

The problem that underlies this activity is to see the condition of the school environment that requires counseling about the use of electrical equipment. The existence of teachers regarding the installation and maintenance of electrical installations in the regions is not well understood, very different from teachers who are in urban areas and moreover those with a background in electrical engineering vocational schools who are classified as advanced both in terms of knowledge level and skills in practice. On the basis of this condition guidance or counseling is carried out for these teachers. Even if they have the skills to install electrical installations, it is hoped that teachers will be able to maintain, repair and install electrical installations, even if they are simple ones. The method used in Community Service activities at SMK N 1 Cisarua, namely Lectures, discussions and exercises. The instructor explains material about the use of electronic devices followed by discussion and questions and answers, while the implementation can be carried out by the teaching team at each school who can consult with the lecturer about saving electricity. As a result of this counseling and training, teachers at SMK N 1 Cisarua can understand the importance of electrical energy and how to use electrical energy efficiently. The conclusion from this activity is that the teaching team at SMK N 1 Cisarua can save electricity in the school and its surroundings so as to reduce the cost of electrical energy.

Abstract

Nowadays, the development of information communication technology (ICT) and global economic growth. Information and communication technology facilitates communication between members of society and the world of work which is not limited by space and time. Communication skills refer to the ability to identify, access, utilize and optimize communication tools and techniques to receive and convey information to other parties. The Electrical Engineering Education FPTK Indonesian University of Education (UPI) intends to conduct training on 21st century learning strategies for teachers at SMKN 1 Cisarua. From the results of the implementation of the training activities at this PKM it can be concluded that this activity ran smoothly, the enthusiasm of schools in Bandung Raya in delegating participants was also quite good because this material was felt to be very important for every teacher to be able to make 21st century teaching aids.

Abstract

This research aims to determine the effectiveness of the implementation of Op-Amp trainer in the learning of electronic control systems on the learning outcomes of students in the cognitive and psychomotor domains. The research was conducted using a quasi-experiment method and a sample of 32 students from the experimental and control classes. Data analysis was conducted using hypothesis testing and N-Gain. The results showed that the average learning outcomes of students in both the cognitive and psychomotor domains are good and there was a significant difference in learning outcomes with the experimental class higher. The conclusion of this research is that the implementation of Op-Amp trainer in the learning of electronic control systems is effective in improving student learning outcomes in the cognitive and psychomotor domains when compared to simulation-based learning media.

Abstract

Currently, carbon derived from biomass waste or residues is being intensively utilized as electrodes due to its excellent electrical properties, including high conductivity, appropriate porosity, and a specific surface area suitable for supercapacitor applications. Despite its advantages, the performance of supercapacitors made from biomass-derived carbon is insufficient for engineering applications because of the challenges in obtaining the mesoporous structure of activated carbon (AC). Therefore, this study highlights the potential of biomass-based carbon as the electrodes of a highly efficient supercapacitor, which can facilitate highly efficient current transport in energy storage systems. It comprehensively discusses various biomass material sources and activation methods to produce carbon, with a focus on the physical and electrical properties. Initially, the study discusses carbon activation methods and mechanisms to understand why activating agents and electrolyte solutions have a high specific surface area and specific capacitance. It then concentrates on the chemical activation method and its importance in making AC useful as an efficient electrode. Finally, in this study, various biomass sources were discussed to highlight the performance of supercapacitors electrodes originating from agricultural and wood residues relating to the specific capacitance and capacitance retention. Based on the obtained results, it is concluded that biomass-based carbon materials could be the most advantageous platform material for energy conversion and storage.

Abstract

In Giri Mekar Village, the challenge of public street lighting has become a critical issue affecting the daily lives of its residents. Identifying the need for a sustainable solution, an initiative was launched to introduce automatic lighting technology based on solar cells. Through specially designed socialization and training activities, the youth and members of Karang Taruna were engaged to understand, operate, and maintain this lighting system. The training methodology included theoretical sessions on solar cells, equipment demonstrations, and hands-on installation sessions. As a result of these activities, participants demonstrated significant skill enhancement and understanding, as well as a commitment to implementing and maintaining this technology in their village. The overall initiative not only offered an efficient lighting solution but also promoted the concept of community empowerment in village infrastructure development.
