Abstract

This study examines how to optimize a Support Vector Machine (SVM) model using a dimensionality reduction method called Principal Component Analysis (PCA) to classify images with multiple dimensions. The dataset used is Chessman images with an initial number of features of 12,288. PCA was applied with the aim of retaining 99% of the total variation, resulting in 312 principal components. The results show a significant improvement in computational efficiency: training time was drastically reduced from 29.85 seconds to just 0.17 seconds (168 times faster), and memory usage decreased from 25.83 MB to 0.66 MB (97% more efficient). Although the accuracy experienced a small decrease, namely from 31.58% to 31.22%, PCA still functions as a noise filter that helps improve performance, especially in classes with complex visual patterns, such as an increase in the F1-score of the "Rook" class from 0.32 to 0.37. The conclusions of this study indicate that PCA provides important efficiency improvements without significantly sacrificing classification performance.

Abstract

Coastal tourism safety presents a diplomatic human security agenda, especially for Indonesia as an archipelagic country (≈99,093 km of coastline) and Australia with its mature coastal safety regime. This study aims to assess how the principle of human security is translated into tourism safety governance and how Indonesia-Australia coastal diplomacy produces soft power. The methods used are comparative studies based on policy and document analysis (BPS; BPS-DIY; National Coastal Safety Report 2024; Plan of Action 2025–2029), descriptive statistics of visits, and institutional assessments. The results show a strong recovery in Indonesian tourist arrivals: 4.05 million (2020), 1.56 million (2021), 5.89 million (2022), 11.68 million (2023), and 13.90 million (2024). At the regional level, DIY recorded 9,699 foreign tourists in May 2025 (up 35.94% m/m), with a cumulative total of 32,823 visits from January to May, while domestic tourist movements reached 3,547,415 trips. In Australia, the Surf Life Saving network comprises ≈316 clubs with >198,000 members, 558 patrol services, and 8,857 rescues in 2023/24; epidemiological literature estimates a backwash-related mortality rate of ≈0.11 per million visits. Comparisons indicate a gap in the degree of institutionalization: Australia displays consistent standards, proficiency tests, and exposure-based reporting, while Indonesia still varies between regions. In conclusion, coastal tourism safety is a manifestation of human security which, through coastal diplomacy, generates reputational gains (soft power). Recommendations include establishing national beach SOPs, exposure-based reporting, consistent certification, and multilingual risk communication as prerequisites for integrating human security into tourism governance

Abstract

Penelitian ini bertujuan untuk mengembangkan viralslot platform praktis pengenalan abjad Sistem Isyarat Bahasa Indonesia (SIBI) sebagai media pembelajaran bahasa isyarat yang efektif. Metode yang digunakan adalah algoritma YOLOv5 untuk mendeteksi isyarat bahasa isyarat SIBI. Pengujian dilakukan dalam dua tahap, pertama untuk menguji antarmuka aplikasi yang berhasil menampilkan enam halaman antarmuka pengguna dengan baik viralslot. Kedua, pengujian manual dilakukan untuk mendeteksi gerakan bahasa isyarat SIBI dengan membandingkan kelas-kelas aktual yang terdiri dari 26 kelas viralslot. Pada pengujian tersebut, beberapa kelas seperti 'A' dan 'E' memiliki akurasi deteksi yang rendah karena memiliki gerakan yang hampir sama dengan kelas 'S' atau 'A'. Kelas 'D' juga memiliki akurasi yang rendah karena membutuhkan variasi posisi yang lebih kompleks. Kelas 'J' memiliki gestur yang cukup rumit karena ada gerakan lanjutan yang dilakukan, sehingga memiliki akurasi yang cukup rendah. Hasil deteksi real-time menggunakan kamera ponsel menunjukkan akurasi sebesar 77% (0.77), secara keseluruhan hasil pengujian mencapai akurasi yang cukup baik. Diharapkan dengan adanya platform ini dapat mempermudah dan memperlancar komunikasi antara masyarakat umum dengan teman tuli.Kata kunci : Bahasa Isyarat, Deteksi Objek, Komunikasi Tuli, Sibi, Yolo.

Abstract

Purpose: This study aims to develop an integrative conceptual framework linking Sharia objectives (maqasid al-sharia) with sustainable halal tourism in Southeast Asia through research landscape mapping, identification of key findings, and a comprehensive literature synthesis. Method: This study employs a mixed-methods approach integrating bibliometric analysis with a systematic literature review based on the PRISMA 2020 protocol. A total of 62 Scopus-indexed articles from 2019 to 2025 were analyzed using VOSviewer software to identify major thematic clusters. Result: The bibliometric analysis revealed five main thematic clusters: halal tourism and Islamic marketing; tourist satisfaction and loyalty; sustainable tourism; Muslim tourists and destination development; and religiosity and local wisdom. The findings indicate that maqasid al-sharia serves as an integrative axis capable of bridging fragmentation among these clusters. The dynamics of implementing sustainable halal tourism in Malaysia, Brunei Darussalam, and Indonesia reveal diverse approaches grounded in maqasid al-sharia principles. Contribution: This study demonstrates that maqasid al-sharia can serve as a normative foundation for developing halal tourism that is ecologically, socially, and economically sustainable. The resulting integrative conceptual framework offers practical implications for policymakers, destination managers, and industry stakeholders in building a tourism ecosystem that is not only Sharia-compliant but also resilient, while contributing new theoretical knowledge by bridging the gap between Sharia principles and the global sustainability agenda.
