Abstract

The Data Logger is an electronic device designed to automatically and continuously store data. Data loggers are widely used in various fields, including the storage of weather parameter data. Generally, a data logger consists of sensor devices, a processor, and storage media. This paper discusses the design of a dynamic data logger that allows the selection of sensor input types and storage media such as an SD card or a cloud database. The data logger comprises hardware devices, including five weather parameter sensors, a processor and a communication module using ESP32, a timing system using RTC, and local storage media in the form of an SD card. Additionally, there is a computer-based user interface built using Visual Basic. The connection between the user interface application and the data logger hardware is established using serial communication. Overall system testing results indicate that all features of the data logger system have operated well.

Abstract

To improve flaw identification in contemporary electronics manufacturing, this study introduces an automated printed circuit board (PCB) inspection system that integrates NI Vision Builder with NI MyRIO. The device effectively detects flaws like missing parts, open circuits, and over-etched traces by utilizing a high-resolution camera and sophisticated methods including color plane extraction and pattern matching. Real-time visualization, classification, and automated data recording are made possible via a LabVIEW-based interface, which makes the inspection process easy to use. A 92% accuracy rate was attained during testing on both bare PCBs and PCB assemblies, indicating better performance than conventional techniques. Although multi-layer and subsurface defect detection still presents difficulties, the system provides a scalable and affordable solution with the possibility to incorporate machine learning and sophisticated imaging in the future for increased adaptability.

Abstract

Perubahan iklim menjadi permasalahan global yang semakin mengkhawatirkan, ditandai dengan meningkatnya suhu bumi, cuaca ekstrem, serta intensitas bencana alam. Namun, sebagian besar masyarakat belum menyadari adanya perubahan iklim ini. BMKG StaKlim Riau memiliki program SLI Literasi yang merupakan program edukasi menyasar generasi muda. Program ini merupakan kegiatan literasi ke sekolah-sekolah untuk sosialisasi dan penyadaran tentang perubahan iklim. Program ini sudah dijalankan sejak tahun 2023, namun belum banyak sekolah sasaran. Kendala yang dihadapi, yaitu keterbatasan SDM, keterbatasan akses ke sekolah-sekolah, dan keterbatasan konten digital untuk mendukung literasi iklim. Melalui kegiatan pengabdian masyarakat ini telah dilakukan rangkaian kegiatan mulai dari perencanaan, sosialisai, lomba video, aksi penanaman pohon, dan seminar perubaan iklim. Dalam sudut pandang mitra, kegiatan ini adalah SLI Literasi. Hasil kegiatan telah menjadi solusi permasalahan mitra, yaitu penyediaan sumber daya manusia sebagai pelaksana kegiatan SLI Literasi, membantu akses sekolah-sekolah yang berada dalam jejaring kampus Politeknik Caltex Riau, dan memberdayakan generasi muda untuk membuat konten digital berupa video perubahan iklim sehingga menambah konten digital yang dimiliki oleh mitra.   Kata Kunci: Perubahan iklim, SLI Literasi, edukasi, generasi sadar iklim.

Abstract

This paper presents the design and development of a twin-motor aeropendulum (half-quadcopter) system as a control systems learning platform using a fuzzy logic controller (FLC). The system is implemented using a real plant in the form of a half-quadcopter, an IMU MPU6050 sensor combined with a complementary filter for angle estimation, and an integration of Arduino and Matlab-Simulink for controller design and response visualization. Compared to conventional PID controllers, the FLC is selected due to its ability to handle system nonlinearities without requiring an accurate mathematical model. The main contribution of this work lies in the development of a low-cost educational platform that integrates a real plant, a non-contact sensor with improved durability, and real-time system response visualization. Experimental results at a 30° setpoint show a rise time of 0.5 s, a settling time of 5.8 s, a maximum overshoot of 21.3%, and a steady-state error of 0.2%, along with good disturbance rejection capability. These results demonstrate that the proposed system is effective and suitable as an interactive learning platform to enhance students’ understanding of control system concepts.
