<![CDATA[This study aims to evaluate the Virtual Processing Station as a simulation-based learning medium in the context of engineering education, based on student perceptions. Student perceptions of this medium were evaluated based on four main aspects: relevance, attention, interest, and usefulness. This study involved 30 students from the Department of Electrical Engineering Education at Yogyakarta State University who had used the Virtual Processing Station in laboratory practice sessions. Data were collected through a questionnaire with 17 statements using a Likert scale and supplemented with qualitative feedback from respondents. The results showed that this learning medium was very well received by students, with an average rating of 90.59%. The relevance aspect received the highest score (92.92%), followed by the interest aspect (90.83%) and usefulness (90.56%). Although the attention aspect received a slightly lower score (84.72%), the medium was still considered quite effective in capturing students' attention during the learning process. Positive comments from respondents emphasized the effectiveness of this medium in helping students understand both the practical and theoretical concepts of PLC-based industrial automation systems. The conclusion of this study indicates that the Virtual Processing Station has great potential in supporting more interactive and efficient engineering learning. However, there is still room for improvement in areas such as the user interface and visualization. Future research should focus on assessing the short-term and long-term impacts of this medium, particularly through larger sample sizes and objective assessments of student performance before and after using the Virtual Processing Station. This approach will provide deeper insights into how these medium influences learning outcomes and the development of practical skills in engineering education.]]>

Setiap aktivitas yang berkaitan dengan informasi tentang jumlah peserta pasti akan melibatkan presensi. Merancang prototipe sistem presensi mahasiswa menggunakan sensor Radio Frequency Identification (RFID) berbasis Arduino Uno. Sistem RFID ini mencakup elemen tag dan pembaca. Tag digunakan sebagai alternatif kartu ID, sementara pembaca berfungsi untuk mengambil informasi tentang kehadiran mahasiswa. Alat yang dikembangkan terhubung dengan basis data kehadiran mahasiswa dan bertindak sebagai pengganti sistem absensi manual. Basis data kehadiran diintegrasikan dengan perangkat lunak PLX-DAQ. Integrasi dengan basis data memungkinkan penyimpanan data secara otomatis, memudahkan administrasi dalam merekam kehadiran mahasiswa. Alat dapat memberikan informasi kehadiran berdasarkan data masuk dan pulang mahasiswa. Penggunaan Real Time Clock DS3231 memastikan akurasi penghitungan waktu dari detik hingga tahun, dengan kemampuan penyimpanan data secara real-time.]]>

<![CDATA[Pada Penelitian ini kami merancang system kendali pencahayaan dengan mikrokontroler Arduino R3 dan sensor suara. Dengan demikian, alat ini terhubung ke program pada aplikasi Arduino IDE yang sudah terisntal pada system. Setelah terhubung ke program maka alat dapat dijalankan dengan cara menyambungkan komponen ke laptop lalu menjalankan programnya dan unggah program ke Arduino R3. Maka system control lampu akan berjalan dengan perintah yang ada pada program. Namun jika relay tidak di atur sensitifitasnya atau sensitifitas program tidak diatur maka akan susah untuk merespon relaynya. Sistem ini bertujuan untuk memudahkan pengguna supaya menghidupkan lampu untuk belajar di sekitar meja belajar tanpa menekan saklar. Hasil pengujian system bahwa tekanan suara dari sensor suara itu sendiri yaitu 500hz, ketika kurang dari itu maka sensor mungkin tidak akan merespon. ]]>

<![CDATA[Circuit Breaker (CB) atau Pemutus Tenaga (PMT) merupakan perangkat yang berfungsi untuk memutus aliran listrik dalam kondisi berbeban. Studi ini bertujuan untuk mengevaluasi kinerja circuit breaker saat gangguan terjadi serta menganalisis faktor-faktor yang memengaruhi kinerjanya di Gardu Induk Bantul. Hasil penelitian menunjukkan bahwa kinerja circuit breaker pada sisi 150 kV Gardu Induk Bantul masuk dalam kategori baik. Penilaian ini didasarkan pada pengaturan waktu relai arus lebih yang terpasang pada penyulang 20 kV Gardu Induk Bantul nilainya tidak kurang dari 0,3 detik. Keputusan ini diambil untuk mencegah tripping berlebihan karena arus inrush dari transformator yang sudah terhubung ke jaringan lainnya. Faktor-faktor yang mempengaruhi kinerja circuit breaker atau PMT meliputi besarnya arus gangguan hubung singkat. Arus gangguan dipengaruhi oleh jarak dari titik gangguan, semakin jauh, arusnya cenderung lebih kecil, dan sebaliknya. Selain itu, pengaturan relai arus lebih juga berperan penting. Semakin cepat relai merespons untuk memerintahkan circuit breaker atau PMT memutus jaringan, semakin baik kinerjanya]]>

<![CDATA[Pada penelitian ini, dikembangkan sebuah sistem monitoring suhu lingkungan berbasis Arduino Uno yang dilengkapi dengan modul Real-Time Clock (RTC) DS3231. Tujuan utama dari sistem ini adalah untuk mengukur, mencatat, dan menampilkan data suhu lingkungan secara real-time dengan akurasi tinggi. Arduino Uno berfungsi sebagai pengendali utama yang mengintegrasikan sensor suhu DS18B20 untuk pengukuran suhu dan RTC DS3231 untuk penyediaan waktu yang akurat. Data suhu yang diperoleh dari sensor kemudian disimpan bersama dengan stempel waktu dari RTC dalam kartu SD, sehingga memungkinkan analisis data historis secara komprehensif. Hasil pengujian menunjukkan bahwa sistem ini mampu mengukur suhu dengan akurasi yang baik dan dapat beroperasi secara kontinu dalam jangka waktu yang lama. Implementasi sistem ini menawarkan solusi yang efektif dan ekonomis untuk pemantauan suhu lingkungan secara real-time, dengan potensi untuk pengembangan lebih lanjut menjadi sistem yang lebih kompleks atau terintegrasi dengan jaringan IoT (Internet of Things).]]>

<![CDATA[This research focuses on integrating the Computational Thinking (CT) concept of automation system in vocational education to address the high costs and scarcity of educational resources in practical learning. The rapid industrial expansion of automation, particularly in Modular Production Systems (MPS), necessitates that students grasp both the components' functionalities and operational principles. Another point that needs to be considered is the integrated CT concept in the learning process. The CT for 21st-century skills, this research aims to facilitate knowledge absorption through systematic problem-solving strategies. To reduce cost and scarcity, this research developed an Interactive Virtual Reality Testing Station (IVRTS) employing a CT methodology to replicate MPS functions effectively in a Flexible Manufacturing System (FMS) Laboratory setting. Developing an Interactive Virtual Reality Testing Station (IVRTS) with a CT approach to simulate the working process is expected to overcome this problem in the Flexible Manufacturing System (FMS) Laboratory. The research procedure adopted from Lee Owens' ADDIE development procedure aims to create a CT-based IVRTS as an innovative educational tool. Experimental validation will compare the efficacy of CT-enhanced IVRTS against traditional methods among 36 students from higher schools. Based on the results of research on the IVRTS indicates its significant potential, receiving mainly "Good/Worth It" feedback. Despite the overall positive reception, users reported issues regarding its complex nature and the necessity for ongoing technical support. Refinements to make the system more intuitive and autonomous by streamlining the interface and clarifying functions are essential for broader user adoption.]]>
