A Bibliometric Analysis Of Psychological Measurement In Sports: Mapping Global Trends, Collaborations, Thematic Developments

Noor Akhmad
Abstract: Psychological measurement tools are fundamental in sports psychology for assessing mental toughness, performance anxiety, motivation, and resilience in athletes. Despite increasing research in this field, a comprehensive… bibliometric analysis of global trends, collaboration networks, and thematic developments remains limited. This study conducts a bibliometric analysis of 489 Scopus-indexed articles published between 1977 and 2025 to examine publication trends, key contributors, and thematic structures. Results indicate that the United States (32.5%), United Kingdom (15.8%), Germany (9.6%), and Canada (7.3%) are the leading contributors, with emerging research from Slovenia (2.1%) and Uruguay (1.7%). Institutional collaborations highlight strong interdisciplinary ties, particularly between the Center for Addictive Disorders and the Faculty of Medicine and Health. Co-authorship analysis identifies Nikos Ntoumanis (98 publications) and Jennifer Cumming (76 publications) as pivotal researchers, while citation network analysis highlights influential clusters led by Joan L. Duda (4,532 citations) and Andreas Ivarsson (3,215 citations). Bradford’s Law identifies Psychology of Sport and Exercise and Journal of Applied Sport Psychology as core journals. Thematic mapping reveals that mental toughness (18.4%) and resilience (14.7%) are dominant topics, while psychometrics (6.3%) and competitive anxiety (5.1%) remain underexplored. These findings provide strategic insights for enhancing global research collaboration, bridging psychological theory and practice, and guiding future research directions in sports psychology.

Strengthening Geospatial-Based Maritime Surveillance: A Case Study of Adaptation to Extreme Weather in Critical Shipping Lanes

Ida Bagus Putra Budiana, Anwar Kurniadi, Mitro Prohantoro, Rachmat Setiawibawa
Abstract: The Malacca Strait is a vital maritime route that faces significant challenges from high traffic volumes and increasingly frequent extreme weather scenarios. These conditions pose serious risks to navigational safety, environmental… vironmental integrity, and maritime operational security. This study aims to analyse the needs and components of a robust maritime surveillance architecture in the Malacca Strait, particularly in dealing with the impacts of extreme weather and climate change. Additionally, this research will explore the role of geospatial maritime intelligence in enhancing situational awareness and response to maritime incidents. The study findings indicate that a resilient surveillance architecture in the Malacca Strait requires the integration of advanced sensor systems (including multi-spectral radar and meteorological/oceanographic sensors), redundant communication networks, and AI/ML-based intelligent data processing. The adaptive capabilities of the system, including the use of UAVs and USVs, are critical to maintaining operational effectiveness in adverse weather conditions. Additionally, international cooperation and a robust policy framework, encompassing climate change adaptation and ethical considerations, are fundamental to the successful implementation and sustainability of surveillance systems. The Malacca Strait case study highlights specific vulnerabilities and proposes concrete solutions, illustrating a shift from a reactive to a proactive paradigm in maritime security. Building a resilient surveillance architecture in the Malacca Strait is a strategic imperative to safeguard global trade, regional stability, and environmental sustainability amid increasing climate uncertainty. Integrating cutting-edge technology with robust policies and international collaboration will ensure the safety and security of this vital waterway, making it a model for resilient maritime governance globally. A new aspect emphasised is the importance of adapting to climate change and the role of AI in predictive decision-making. This article presents a comprehensive and integrated approach to building a resilient maritime surveillance architecture, with a particular focus on the challenges of extreme weather in the Malacca Strait. Its originality lies in its emphasis on multi-sensor data fusion, the role of artificial intelligence in predictive analytics, and the integration of climate change adaptation into surveillance system design. Additionally, the article underscores the importance of a robust policy framework and international cooperation as the cornerstones of maritime surveillance resilience, offering a blueprint applicable to other critical maritime routes worldwide

Implementasi Metode CNN Untuk Klasifikasi Status Stunting Pada Balita

Abrori, Syariful, Zaehol Fatah
Abstract: Stunting pada balita merupakan permasalahan kesehatan masyarakat yang serius dan memerlukan penanganan segera melalui deteksi dini yang akurat. CNN (Convolutional Neural Network) merupakan metode yang akurat, efektif dan… tepat sasaran dalam memberikan hasil yang akurat dan presisi. Implementasi metode CNN dapat mengklasifikasikan status stunting pada balita berdasarkan parameter antropometri dan karakteristik kesehatan. Dataset yang digunakan terdiri dari 6.500 sampel data balita dengan 8 variabel meliputi jenis kelamin, usia, berat lahir, panjang lahir, berat badan, panjang badan, riwayat ASI eksklusif, dan status stunting. Metodologi yang digunakan melibatkan serangkaian tahapan preprocessing data termasuk standardisasi fitur menggunakan StandardScaler, pemisahan data training (80%) dan testing (20%), serta penggunaan arsitektur CNN yang terdiri dari layer konvolusi 1D dengan 32 filter, max pooling, dan dense layer. Model dilatih menggunakan optimizer Adam dengan fungsi loss categorical crossentropy selama 10 epoch dan batch size 32. Evaluasi performa model dilakukan menggunakan berbagai metrik termasuk accuracy, precision, recall, dan F1-score. Hasil penelitian menunjukkan bahwa model CNN yang dikembangkan mencapai performa yang sangat baik dengan akurasi 90%, precision 89%, recall 92%, dan F1-score 91%. Analisis confusion matrix mengkonfirmasi kemampuan model dalam mengklasifikasikan kedua kelas yaitu pada stunting dan non-stunting secara seimbang. Temuan ini mengindikasikan bahwa implementasi CNN efektif dalam mengidentifikasi status stunting pada balita dan berpotensi menjadi alat bantu yang berharga dalam screening stunting di fasilitas kesehatan.

Geryl Valeri Evans, Doan Juan Panjaitan, Gabriel Siburian, Levirisky Siahaan, Muhammad Nur Hidayat, Pristi Suhendro Lukitoyo
Abstract: The spread of Islam on Sumatra Island originated in coastal regions before expanding into the hinterlands. Utilizing a historical approach, this study reveals that maritime trade routes served as the gateway for traders… and missionaries from Arabia, Persia, and Gujarat to engage in commerce and dawah across Sumatra. Islam initially flourished in Barus, Samudera Pasai, and Aceh before eventually expanding into the interior through river networks, intermarriage, and the political influence of the sultanates. The findings of this study indicate that the process of Islamization in Sumatra was not uniform; in coastal areas, Islam tended to be more Cosmopolitan, whereas in the interior, cultural acculturation with local traditions occurred. The success of this expansion marked the starting point of a religious transformation across the Indonesian archipelago

Bahar, Ahmad, Bagus Adhi Kusuma
Abstract: Ikan hiu adalah kelompok hewan yang menarik dan menakutkan di dunia laut. Mereka termasuk dalam kelas Chondrichthyes bersama dengan pari dan hiu bersirip. Mereka dapat ditemukan di berbagai perairan dan memiliki peran penting… nting sebagai indikator kesehatan ekosistem laut. Namun, populasi ikan hiu terancam karena penangkapan ikan ilegal dan kurangnya konservasi. Dalam proses mengidentifikasi dan mengklasifikasikan spesies hiu, peneliti membuat program dengan menggunakan teknik pengenalan visi komputer, seperti Convolutional Neural Network (CNN), dapat sangat membantu. Salah satu arsitektur CNN yang efektif adalah ResNet50, yang terbukti berhasil dalam klasifikasi gambar. Dengan menggunakan 4720 data citra ikan hiu dari 14 kelas model ResNet50 berhasil mencapai akurasi 86% dalam klasifikasi spesies ikan hiu. Model ini dapat digunakan untuk mengidentifikasi spesies hiu dengan baik, kecuali pada beberapa kelas tertentu yang perlu diperbaiki.
