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 ┬Ám 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

In this study, aimed to develop low-cost sensor based on fiber optic to assess ammonia index for fishpond application. Here, the simple design was proposed by using Evanescent wave type to assess ammonia index during acid rain event. The experiment result showed maximum absorption loss with variation ammonia mass 1~5% with wavelength 1310 nm from Optical Light Source (OLS) is 27.56 dBm while Optical Spectrum Analyzer (OSA) reached 25.86 dBm. We had calculated RMSE, MAE, and Percent Error (PE) value both of the device (Low-cost fiber optic chemical sensor and OSA) are 1.692%, 0.916%, and 98.833% respectively. A good result from low cost fiber optic chemical sensor has successful developed with lowest production less than 1,455 USD per-year.

Abstract

Micropump adalah komponen penting dalam sistem mikrofluida dan digunakan untuk mengontrol jumlah cairan yang tepat dalam ukuran mikroliter hingga nanoliter. Penelitian ini bertujuan mengoptimasi desain 3-D micropump yang menggunakan aktuator piezoelektrik. Metode yang digunakan dalam penelitian ini adalah metode simulasi dengan perangkat lunak COMSOL Multiphysics 5.6. Micropump dianalisis dengan memvariasikan radius inlet dan outlet, tegangan penggerak, serta frekuensi kerja untuk menemukan laju aliran tertinggi. Ukuran radius pada inlet dan outlet divariasikan dari 0,6 mm sampai 1,4 mm dengan interval sebesar 0,2 mm. Hasil penelitian menunjukkan bahwa radius yang lebih tinggi memiliki laju aliran yang lebih rendah karena efisiensi rektifikasi yang lebih rendah. Namun, terdapat nilai optimum pada radius 0,8 mm dengan laju aliran tertinggi pada inlet dan outlet masing-masing 0,941 mL/menit dan 0,957 mL/menit. Selain itu, kenaikan tegangan penggerak menyebabkan peningkatan laju aliran. Namun, pengaruh kenaikan frekuensi kerja terhadap laju aliran berbanding terbalik dengan kenaikan tegangan penggerak yang diterapkan pada aktuator piezoelektrik. Semakin tinggi nilai frekuensi kerja maka laju aliran fluida pada inlet maupun outlet terus mengalami penurunan. Laju aliran pada frekuensi yang lebih rendah menyebabkan membran dapat mencapai titik maksimum amplitudo getaran. Hasil dari penelitian ini dapat dimanfaatkan untuk pengembangan dan optimasi desain pada aplikasi biomedis.

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.
