Abstract

Penelitian ini mengeksplorasi metode pengukuran dan pengendalian suhu dalam furnace yang digunakan untuk proses pemanasan baja mentah, dengan tujuan memastikan suhu yang diukur di setiap zona furnace dapat dikontrol dan dipertahankan pada tingkat yang optimal untuk pembakaran. Pengukuran suhu dilakukan dengan menggunakan sensor termokopel tipe K yang ditempatkan di tiga zona utama furnace, yaitu zone 1, zone 2A, dan zone 2B. Sensor termokopel dipilih karena memiliki kemampuan untuk mengukur suhu dalam rentang yang luas, dari -200 °C hingga 1250 °C, serta ketahanannya terhadap suhu tinggi, respon cepat, dan akurasi pengukuran yang tinggi dengan kesalahan kurang dari 1 °C. Hasil pengukuran menunjukkan bahwa suhu di zone 1 mencapai 746,7 °C, di zone 2A mencapai 937,0 °C, dan di zone 2B mencapai 877,4 °C. Meskipun sensor termokopel mampu memberikan hasil yang akurat, suhu yang terukur belum mencapai standar yang dibutuhkan untuk pembakaran baja yang optimal, yaitu 1150 °C di zone 1 dan 1250 °C di zone 2A dan 2B. Oleh karena itu, diperlukan penyesuaian lebih lanjut dalam pengaturan furnace untuk mencapai suhu yang diinginkan. Untuk memfasilitasi pengendalian suhu, penelitian ini juga menggunakan sistem kontrol PID yang terintegrasi dengan Human Machine Interface (HMI). Sistem ini memungkinkan pemantauan suhu secara real-time dan memberikan kemudahan dalam melakukan penyesuaian suhu sesuai kebutuhan. Dengan kontrol yang tepat, proses pembakaran dalam furnace dapat dilakukan secara maksimal, yang berpotensi meningkatkan efisiensi energi dan kualitas produk baja yang dihasilkan. Penelitian ini memberikan kontribusi signifikan dalam pengembangan metode pengukuran dan kontrol suhu yang lebih efektif dalam industri metalurgi.

Abstract

This study investigates energy efficiency challenges during laboratory activities. Inefficient energy use in the practicum phase remains a critical issue, prompting the exploration of innovative forecasting models. This research employs artificial neural network (ANN) models integrated with principal component analysis (PCA) to predict energy consumption and optimize usage. The findings reveal that PCA components, including eigenvalues, eigenvectors, and matrix covariance values, significantly influence the ANN model's performance in forecasting energy production. The ANN training achieved a high correlation coefficient (R=1) with a mean squared error (MSE) of 0.045931 after 200,000 epochs, demonstrating the model's robustness. While testing results showed a moderate correlation (R=0.46169), the models demonstrated potential for refinement and scalability. This integration of ANN and PCA models provides a reliable framework for accurately forecasting energy usage, offering an effective strategy to enhance energy efficiency in laboratory settings. By optimizing energy consumption, this approach has the potential to reduce operational costs and environmental impact. The strong performance metrics highlight the practical utility of these models in educational contexts, contributing to sustainable energy management and better resource allocation. Furthermore, the reduction in energy-related environmental impacts underscores the broader applicability of these models for fostering sustainable development in similar contexts.

Abstract

Fire is a disaster that cannot be predicted and often has a significant impact on human life, both materially and non-materially. Fires are usually detected only after they have grown large, resulting in unavoidable losses. Various factors, such as short circuits in electrical networks, LPG gas leaks, and human negligence, are the main causes of fires. In this situation, an early detection system that provides real-time information is needed to minimize the impact of the fire. This study aims to design a prototype of a Multisensor Fire Detection System Based on the Internet of Things (IoT) that integrates a flame sensor, MQ-2 gas sensor, and DHT22 temperature sensor with the Blynk application to provide real-time notifications. This system is also equipped with an LCD for warning display and a buzzer as an alarm. The prototype has been tested in a controlled environment that simulates fire conditions, including gas leaks and high temperatures, with several trials conducted to verify its reliability. The results showed that the system could detect fire at a maximum distance of 100 cm, hazardous gas concentrations starting from 600 ppm, and temperatures exceeding 35°C as the threshold for fire detection. However, its performance may be affected in environments with high humidity levels or areas with poor network connectivity. With effective integration of hardware and software, this prototype helps users detect potential fires at an early stage and minimize the risk of fire-related losses

Abstract

The integration of digital technology in higher education has accelerated the need for innovative pedagogical approaches that foster active learning and digital competence. Project-Based Learning (PjBL) supported by e-learning provides authentic, technology-driven experiences that are particularly valuable in vocational education, where students must connect theory with practice. This study examined the effect of PjBL using e-learning on student learning outcomes in vocational education courses at the Department of Information Technology Education, Universitas Negeri Surabaya. A quasi-experimental pretest–posttest control group design was employed with 64 purposively selected undergraduate students from the 2024/2025 academic cohort. Participants were assigned equally to an experimental group (n = 32), which received PjBL integrated with e-learning, and a control group (n = 32), which received conventional lecture-based instruction. Data were collected through pretests and posttests and analyzed using descriptive statistics, independent samples t-test, and effect size calculations. Findings revealed that the experimental group achieved significantly higher posttest scores (M = 84.63, SD = 5.21) compared to the control group (M = 76.88, SD = 6.02). The independent samples t-test confirmed the significance of the difference (t = 5.67, p < 0.001), while Cohen’s d (d = 1.32) indicated a large effect size. These results demonstrate that integrating PjBL with e-learning substantially improves learning outcomes in vocational education. In conclusion, PjBL supported by e-learning offers an effective instructional strategy for enhancing problem-solving, higher-order thinking, and active student engagement. The findings suggest that aligning pedagogy with digital platforms can optimize learning effectiveness and strengthen students’ readiness for professional challenges.
