Abstract

Perkembangan teknologi komputasi mempermudah proses pembelajaran. Augmented reality (AR) digunakan untuk membangun aplikasi praktikum rangkaian listrik menggunakan aplikasi Unity3D untuk meningkatkan pemahaman pada praktikum rangkaian listrik. Aplikasi memiliki fitur-fitur yaitu tugas pendahuluan, AR breadboard, AR multimeter dan AR power supply, modul praktikum dan presensi. Blackbox Testing, kuesioner, pengaruh cahaya lingkungan, derajat kemiringan, resolusi kamera, dan smartphone prosesor digunakan dalam uji coba untuk rentang jarak dan kestabilan aplikasi mendeteksi marker. Semakin gelap cahaya lingkungan, maka jarak deteksi akan semakin menurun dan semakin kecil sudut kemiringan maka jarak deteksi akan semakin menurun dan sebaliknya. Semakin tinggi resolusi sebuah smartphone maka semakin stabil jarak deteksi marker dan semakin canggih prosesor dari smartphone maka semakin cepat smartphone dapat mendeteksi marker. Dari hasil kuesioner yang disebarkan kepada lima orang responden, didapatkan hasil bahwa responden menilai aplikasi memiliki tampilan yang menarik dan mudah untuk digunakan, fitur dan tombol pada aplikasi dapat bekerja dengan baik pada smartphone responden dan fitur favorit yang dipilih oleh responden adalah fitur belajar alat dan fitur langkah praktikum. Mayoritas responden praktikum rangkaian listrik (64%) sangat setuju bahwa aplikasi yang digunakan memiliki tampilan menarik dan dapat membantu kegiatan praktikum, serta fitur tugas pendahuluan dengan tampilan augmented reality dan interaksi aplikasi menarik bagi 90% responden. Selain itu, aplikasi tersebut memiliki fitur-fitur yang memenuhi kebutuhan praktikan dan dapat membantu proses pembelajaran.

Abstract

This research aims to assess the application of microscopic imaging technology in analyzing Bacillus sp. bacteria, focusing particularly on the effectiveness of gradient operators in the Canny Edge Detection Algorithm. The study encompasses an in-depth evaluation of four principal gradient operators: Sobel, Prewitt, Roberts, and Scharr, to enhance edge detection accuracy in microscopic images. Analysis revealed that Sobel and Scharr excel in precision, with Sobel standing out in creating texture homogeneity and Scharr demonstrating superior inter-pixel correlation, both vital for ensuring visual accuracy of the images. Additionally, these operators show remarkable performance in Precision and Recall, effectively identifying relevant edges with minimal errors. Conversely, the Roberts operator, with its higher F-measure, offers an ideal equilibrium between precision and recall, making it a suitable choice for broader applications. Edge Co-Occurrence Matrix (ECM) analysis indicated that Sobel and Scharr possess higher contrast values, thereby emphasizing the sharpness of edge delineation. Conclusively, the study identifies the Scharr operator as most fitting for the analysis of microscopic bacterial imagery, owing to its capability in maintaining inter-pixel correlation and enhanced classification performance. This positions the Scharr operator as a highly applicable tool for microscopic bacterial studies, crucial in the accurate and consistent recognition of bacterial patterns. These findings significantly advance our understanding of Bacillus sp., directly impacting disease diagnostics and biotechnology. The research underscores the critical importance of selecting appropriate gradient operators in microscopic analysis and highlights the need for ongoing innovation and exploration in microscopic imaging technology.

Abstract

The application of magnetic levitation that is currently developing is on land transportation in the form of maglev trains.Magnetic levitation is a system that uses an electromagnetic field to work against the force of gravity. The common point in application the magnetic levitation is used is the lack of contact and thus no friction this increases efficiency and system life. Magnetic levitation technology is still developing today. The magnetic levitation ball requires a good control method to maintain the ball's position on the mat against the earth's surface. This research implements Hybrid Proportional Integral Derivative (PID) control with fuzzy as a control system on magnetic levitation ball. The research for magnetic levitation ball uses Auto Tuning PID and Fuzzy–Takagi Sugeno controls. In the PID system, an auto-tuning system is carried out on simulink MATLAB R2019, and in fuzzy the function is designed to store input in the form of error (e) and delta error (de) while the function displays output in the form of effective height distance. Then defuzzification on fuzzy uses the Center of Area (COA) method. In magnetic levitation research, objects can experience ideal service conditions at a distance of 0.006 m from the end of the solenoid. in the transfer function test to reach a steady state, the risetime is 0.007817 s, the overshoot is 157.051%. then the PID tuning test to reach a steady state obtained a risetime of 0.214371 s, an overshoot of 0.460%. and in the fuzzy-PID hybrid test to reach steady state, the risetime is 0.044902 s and the overshoot is -0.357%.
