Workshop Pemanfaatan Teknologi Internet of Things (IoT) menggunakan Mikrokontroler ESP32 untuk Guru-Guru SMK

The rapid advancement of information technology and telecommunications has caused Internet of Things (IoT) technology to be increasingly developed and utilized in various activities and tasks at the home, office, school, industry, and others. 24-hour connectivity and various automation features make IoT an effective way to remotely monitor and manage jobs. In the context of learning in Vocational High Schools (SMK), ideally, the use of IoT technology applications is taught by teachers in the field of industrial electronics expertise. The uneven understanding and technical skills of teachers about the application of IoT technology is one of the factors that have not updated the ability of vocational students with IoT technology information. From these problems, the solution offered is to provide technical knowledge and skills to teachers about the use of IoT using a microcontroller so that they can teach it to students. The workshop/training was conducted online which was attended by 20 (twenty) teachers from several vocational schools in the Jakarta, Bekasi, Cibinong, and Bogor areas. In this workshop, theoretical and practical learning about the use of IoT technology is given. The material taught is the development of IoT, the use of the ESP32 IoT development board, and some practical examples using the ESP32 board. In this workshop, IoT learning e-modules (theory and practice) were also distributed which can be used by teachers for independent learning and as teaching materials in SMK. From the workshop, an overview of the understanding and technical skills of teachers regarding IoT technology was obtained which still needs to be improved. The participants were very enthusiastic about participating in the IoT workshop because they got new and useful information and knowledge to improve their competence in the field of industrial electronics technology. The usefulness of this workshop was felt by the participants who gave a positive impression of the material taught by the instructor/lecturer. Abstrak Pesatnya kemajuan teknologi informasi dan telekomunikasi, menyebabkan teknologi Internet of Things (IoT) makin berkembang dan dimanfaatkan dalam berbagai kegiatan dan tugas di rumah, kantor, sekolah, industri, dan lainnya. Konektivitas 24 jam serta berbagai fitur otomasi menjadikan IoT sebagai cara efektif untuk memantau dan mengelola berbagai pekerjaan dari jarak jauh. Dalam konteks pembelajaran di Sekolah Menengah Kejuruan (SMK), maka idealnya pemanfaatan aplikasi teknologi IoT diajarkan oleh para guru bidang keahlian elektronika industri. Belum meratanya pemahaman dan keterampilan teknis guru tentang aplikasi teknologi IoT, menjadi salah satu faktor belum ter-update nya kemampuan siswa SMK dengan informasi teknologi IoT. Dari permasalahan tersebut maka solusi yang ditawarkan adalah dengan memberikan pengetahuan dan keterampilan teknik kepada guru tentang pemanfaatan IoT menggunakan mikrokontroler sehingga dapat mengajarkannya kepada siswa. Workshop/pelatihan dilaksanakan secara daring yang diikuti peserta guru dari beberapa SMK di wilayah Jakarta, Bekasi, Cibinong dan Bogor sebanyak 20 (dua puluh) orang. Dalam workshop ini diberikan pembelajaran teori dan praktikum tentang pemanfaatan teknologi IoT. Materi yang diajarkan adalah perkembangan IoT, pemanfaatan ESP32 IoT development board, dan beberapa contoh praktikum menggunakan ESP32 board. Dalam workshop ini juga dibagikan e-modul pembelajaran IoT (teori dan praktik) yang dapat digunakan para guru untuk pembelajaran mandiri dan sebagai bahan ajar di SMK. Dari workshop tersebut didapatkan gambaran terkait pemahaman dan keterampilan teknis para guru tentang teknologi IoT yang masih perlu ditingkatkan. Para peserta sangat antusias mengikuti workshop IoT karena mendapatkan informasi dan pengetahuan yang baru dan berguna untuk meningkatkan kompetensinya di bidang teknologi elektronika industri. Kebermanfaatan workshop ini dirasakan sekali oleh para peserta yang memberikan kesan positif dari materi yang diajarkan oleh instruktur/narasumber.

Student’s mathematical connection ability through GeoGebra assisted project-based learning model

Several previous studies related to mathematical connection abilities and GeoGebra-assisted project-based learning models, but this research focuses on improving students' mathematical connection ability in the Integral Calculus course. This study examines the improvement of mathematical connection abilities through a project-based learning model assisted by GeoGebra. The research method used was a quasi-experimental design with a pretest-posttest nonequivalent multiple group design. The population is students of the Mathematics Education Study Program at the University in West Java, Indonesia. 1A and 1B students, which are used as samples. The technique of taking the research subject uses purposive sampling. The instrument consisted of a mathematical connection ability test with three essay questions. The test in this study used a pretest and posttest students' mathematical connection ability and the Group Embedded Figure Test (GEFT). The data analysis technique used an independent sample t-test and a two-way ANOVA test. The results showed that the improvement of students' mathematical connection ability who obtained the GeoGebra-assisted project-based learning model was better than students who obtained the project-based learning model. There is no interaction effect of learning models and cognitive styles on the achievement and improvement of students' mathematical connection abilities. The implication of this research is to provide significant changes in student learning habits in integral calculus courses to use technology and foster high self-regulated learning. This research has implications for universities implementing project-based learning models combined with other technology applications in other subjects.

Usability Cost-Benefit Analysis for Information Technology Applications and Decision Making

Usability is an important quality attribute for information technology (IT) applications. However, integrating usability design and evaluation as an integral part of the development processes in information technology development organizations is still a challenge. This chapter gives an overview on the usability cost-benefit analysis models and provides some example cases of the importance of usability. These models and cases can be used by usability professionals to motivate the organizational management to provide resources for usability work and to integrate usability work as part of the development process. The target audience for this chapter are professionals and researchers working in the field of IT, managers in IT development organizations, as well as managers in organizations acquiring and using IT.

System-on-chip integrated circuit technology applications on the DIII-D tokamak for multi-field measurements

Several mm-wave diagnostics on the DIII-D tokamak provide multi-scale and multi-dimensional measurements of plasma profile evolution and turbulence fluctuations. Mm-wave fusion plasma diagnostics that adopt system-on-chip integrated circuit technology can provide better space utilization, flexible installation, and improved sensitivity. In order to further extend this technology for additional fusion facilities with a higher toroidal magnetic field, V-band (55–75 GHz) and F-band (90–140 GHz) chips for Microwave Imaging Reflectometer (MIR) and Electron Cyclotron Emission Imaging (ECEI) instruments are developed and tested in the Davis Millimeter Wave Research Center (DMRC). Current measurement data show that correlation between these SoC-based diagnostic instruments with other state-of-the-art diagnostics enables co-located multi-field turbulence fluctuation measurement.

Supply Chain View of Tourism

Tourism being observed as a supply chain, this article describe its practices under a conceptual research framework with a special reference to education tourism. The author projects the education tourism as a continuum where both service supply chains of education and tourism are integrated. The research implication is directed towards the cross-sectoral objectives of communities involving the tourists, students and destination communities. The original thoughts and value propositions in this research are portrayed as a supply chain framework. Unlike goods supply chain management, the service supply chain of education tourism grows complex due to the coexistence of the overlapping service objectives for education and tourism. Education tourism deals with students and tourists frequently interchanging their roles; leveraging the services of the vendors and outsourced partners. The increasing complexity of education tourism demands smart technology applications to manage it as an integrated total supply chain.
