Abstract

Viruses can be transmitted in various ways; one spreads through airborne droplets or the touch of multiple objects. This can occur in any area, including the entrance to the house or access to a room or deposit box. The spread of viruses that cause diseases like COVID-19 has caused many human casualties, and there is still the possibility of similar conditions appearing in the future. Several things need to be done to reduce the chances of spreading disease due to viruses, including developing contactless security support methods. This paper proposes a security system using hand gesture recognition using squeeze and excitation residual networks (SE-ResNet). This research offers a hand gesture recognition system for an automatic door system using SE-ResNet and the residual network (ResNet).

Abstract

The spread of viruses and bacteria through touching door surfaces is essential in maintaining public hygiene and health. In this context, a hand-coded touchless automatic door hardware design has been developed to reduce the spread of diseases through touch. This research aims to create a plan that includes interface development and hardware design to open and close doors automatically without contact. In this research, the automatic door hardware response is tested based on the numeric input from the hand code represented by the numeric database. The input and output control is connected to Python's graphical user interface (GUI). The GUI system design involves tools to connect the Python programming language and the Arduino microcontroller. Based on the experimental results, the hardware design of the automatic door security system based on hand code and Convolutional Neural Networks functions appropriately.

Abstract

ABSTRACTMaterial physics is an important branch of science that studies the properties and applications of various materials from atomic level as the foundation for modern technological development. The importance of this field encouraged the implementation of a socialization activity aimed at improving students’ understanding of the basic concepts and applications of material physics. The activity was attended by 22 participants and consisted of three stages: an initial survey, socialization using the one group pretest–posttest design through interactive and contextual methods, and data evaluation. The average pretest score of 2.22 increased to 3.45 in the posttest, indicating an improvement based on the Likert scale. These results show that the socialization activity contributed positively to enhancing participants’ understanding and interest in the concepts and applications of material physics. The interactive approach used in the socialization proved effective in strengthening participants’ motivation and insight into this field.Keywords: Physics, material, educationABSTRAKFisika material merupakan cabang ilmu penting yang mempelajari sifat dan aplikasi berbagai material dari tingkat atomik sebagai dasar pengembangan teknologi modern.

Abstract

Perkembangan teknologi Computer Vision memungkinkan terciptanya media pembelajaran interaktif yang membantu siswa memahami anatomi wajah secara visual dan praktis melalui interaksi dengan model digital. Penelitian ini bertujuan untuk mengembangkan media pembelajaran anatomi wajah interaktif berbasis Computer Vision dengan integrasi MediaPipe Face Mesh dan Hand Tracking. Sistem dirancang untuk meningkatkan pemahaman konsep anatomi melalui interaksi visual, auditori, dan kinestetik. Metode yang digunakan adalah Research and Development (R&D) dengan tahapan analisis kebutuhan, perancangan sistem, pengembangan, dan uji coba. Aplikasi memiliki dua fitur utama, yaitu fitur praktikum (Edu-Touch, 3D Board, dan Game Anatomi) serta fitur materi (kuis, buku digital, dan video learning). Hasil pengujian menunjukkan bahwa sistem mampu mendeteksi 468 titik landmark wajah dan 21 titik landmark tangan secara real-time dengan akurasi tinggi. Fitur Edu-Touch berhasil menampilkan animasi 3D dan suara penjelasan saat titik wajah disentuh. Fitur 3D Board mengenali pertemuan landmark jari telunjuk (titik 8) dan ibu jari (titik 4) untuk mengontrol rotasi model 3D, sedangkan Game Anatomi berhasil mendeteksi ekspresi wajah sebagai respons terhadap soal. Hasil ini menunjukkan bahwa integrasi MediaPipe efektif dalam menciptakan pembelajaran yang interaktif, menarik, dan adaptif terhadap berbagai gaya belajar

Abstract

Background of study: Tropical karst landscapes harbor exceptional avian biodiversity but pose unique monitoring challenges due to complex topography, cave reverberation, and humidity-driven sound distortion. Conventional ecoacoustic methods fail in these environments, with indices showing weak correlations (r=0.20-0.43) for avian diversity due to insect masking and abiotic interference. Over 83% of karst-endemic birds lack standardized monitoring protocols despite escalating extinction risks.Aims and scope of paper: This review aims to: (1) quantify limitations of current ecoacoustic methods in karst ecosystems, (2) develop a machine learning-enhanced framework addressing topographic and reverberation effects, and (3) establish conservation-ready protocols for endangered karst avifauna. The study synthesizes evidence from 29 studies across hardware innovation, signal processing, and policy applications.Methods: We systematically analyzed 29 studies on acoustic monitoring in karst ecosystems, focusing on machine learning innovations, topographic adaptations, and conservation applications.Result: Topography drives 47% of soundscape variation, surpassing vegetation effects. Machine learning (CNNs/MFCCs) boosts detection accuracy by 22-80% in reverberant caves. Hybrid protocols enable 25-m resolution habitat mapping and precise disturbance monitoring, overcoming tropical "latitude paradox" limitations.Conclusion: This review establishes the first karst-adapted ecoacoustic framework, integrating machine learning with topographic variables to transform monitoring from biodiversity proxy to precision tool. Critical next steps include developing species-specific call libraries, wind-reverberation filters, and policy integration of acoustic baselines for IUCN assessments. The proposed protocols address urgent conservation needs for Earth's most threatened avian sanctuaries.

Abstract

Background: Effective wildlife monitoring is crucial for conservation, but traditional methods are often invasive or lack spatial precision. Passive acoustic monitoring offers a non-invasive alternative, yet deriving meaningful spatial data from sound recordings remains a technical challenge, limiting its utility for detailed ecological analysis. Aims: This study aims to design and simulate a proof-of-concept, low-cost acoustic localization system. The goal is to translate Time Difference of Arrival (TDOA) data from a simple tetrahedral microphone array into two-dimensional spatial heatmaps, providing a visual and quantitative tool to map animal vocal activity for enhanced biodiversity assessment. Methods: A cross-shaped, four-sensor array was modeled. A custom MATLAB GUI was developed to simulate TDOA data from multiple sound sources at varied positions. The system processed this data to generate and compare four distinct types of spatial heatmaps: Gaussian Smoothing, Kernel Density Estimation, Grid Counting, and Inverse Distance Weighting Result: The simulation successfully generated all four heatmap types, validating the core data processing pipeline. The system provided estimated source coordinates with a root mean square error (RMSE) of 0.15-0.25 meters in a controlled 6x6m area and output key statistical metrics like cluster density and distribution. Conclusion: The prototype establishes a feasible framework for transforming raw acoustic signals into actionable spatial intelligence. This work provides a foundational step towards developing affordable, automated systems for long-term ecological monitoring, with future integration of machine learning promising direct species identification and behavioral insight.
