Abstract

Dynamic load analysis is a method for monitoring the health of bridge structures, particularly those made of steel, used to ensure safety and comfort. This analysis yields natural frequencies, which are the frequencies at which an object vibrates when subjected to free vibration. Structural failure due to dynamic loads, caused by resonance when the external frequency aligns with the natural frequency, underscores the importance of bridge structural health monitoring. Extensive research has been conducted on natural frequencies in steel bridge structures, and research mapping using bibliometric and scientometric methods can help analyze research gaps. Bibliometric analysis methods include document trends, publication type, country of origin and document productivity, as well as publication relevance and impact. Scientometric analysis uses VOS Viewer to map and analyze research collaborations. This study aims to describe the relationship between publications, keywords, and trends in crack monitoring studies in concrete structures over the past decade (2015–2025). Data collection from Scopus revealed 54 related documents during that period. Bibliometric and scientometric analyses were used to explore publication trends, collaborations between authors and countries, and the distribution of document types, which showed a sharp increase in publications in 2022. China topped the list in terms of the number of publications, followed by the United States, Belgium, and Italy. This analysis demonstrated the dominance of scientific articles as a document type, highlighting the need for broader international collaboration to further develop steel bridge health monitoring systems and more advanced technologies. The study emphasizes the importance of improving structural health monitoring, particularly regarding the influence of natural frequencies, which remains understudied.

Abstract

The persistent gap between teachers' conceptual knowledge and practical implementation remains a critical challenge in mathematics education. This study investigates how intrinsic versus extrinsic motivational orientations influence teachers' knowledge, understanding, and reward implementation practices in mathematics instruction. Employing an exploratory qualitative case study design, the research examined 14 junior high school mathematics teachers in South Sulawesi, Indonesia, systematically classified by motivational orientation. Data collection encompassed motivational orientation assessments, conceptual knowledge evaluations, case-based understanding tasks, and structured classroom observations. Thematic cross-case analysis was conducted using NVivo 12 software. Findings reveal progressive differentiation patterns: while conceptual knowledge differences remained relatively modest, disparities amplified significantly across understanding and classroom practice dimensions. Intrinsically motivated teachers demonstrated reflective, contextualized, and process-oriented reward strategies, whereas extrinsically motivated teachers exhibited procedural, standardized, and outcome-focused approaches. These results advance theoretical understanding of motivational orientation as a critical moderating variable in knowledge-to-practice transformation processes, offering substantial implications for targeted professional development interventions addressing motivational dimensions in mathematics education.

Abstract

Perkembangan layanan digital pada sektor transportasi publik mendorong meningkatnya interaksi pengguna melalui media sosial, khususnya Twitter. Umpan balik pengguna dalam bentuk opini dan keluhan menjadi sumber informasi penting untuk mengevaluasi kualitas layanan, namun volume data yang besar dan bersifat tidak terstruktur menyulitkan analisis secara manual. Oleh karena itu, penelitian ini bertujuan untuk menganalisis sentimen pengguna terhadap layanan PT Kereta Api Indonesia berdasarkan tweet berbahasa Indonesia menggunakan model fine-tuned IndoBERTweet. Penelitian ini menggunakan pendekatan studi kasus dengan data tweet berbahasa Indonesia yang dikumpulkan melalui proses crawling dan dilabeli ke dalam tiga kelas sentimen, yaitu positif, netral, dan negatif. Model IndoBERTweet dilatih dan dievaluasi pada beberapa skenario preprocessing, meliputi baseline tanpa stopword removal dan stemming, penerapan stopword removal, stemming, serta kombinasi keduanya. Selain itu, dilakukan analisis terhadap pengaruh ketidakseimbangan distribusi data melalui penerapan beberapa teknik penanganan data tidak seimbang, yaitu random oversampling, class weighting, text augmentation, dan random undersampling, yang diterapkan pada skenario dengan performa terbaik. Evaluasi kinerja model dilakukan menggunakan metrik accuracy, precision, recall, macro F1-score, dan confusion matrix. Hasil eksperimen menunjukkan bahwa skenario baseline tanpa stopword removal dan stemming memberikan performa terbaik dengan nilai macro F1-score sebesar 0.7702 dan akurasi 0.8333. Penerapan preprocessing tambahan tidak memberikan peningkatan kinerja yang signifikan dan cenderung menurunkan performa, khususnya pada kelas minoritas. Teknik penanganan data tidak seimbang mampu meningkatkan sensitivitas terhadap kelas positif, namun belum melampaui performa baseline secara keseluruhan. Temuan ini menunjukkan bahwa pendekatan preprocessing minimal dengan perhatian terhadap distribusi data lebih sesuai untuk analisis sentimen berbasis IndoBERTweet pada data Twitter.

Abstract

Program Praktik Pengalaman Lapangan (PPL) merupakan bagian penting dalam proses pembentukan kompetensi mahasiswa calon tenaga kependidikan. Penelitian ini bertujuan untuk mendeskripsikan peran mahasiswa PPL dalam mendukung proses pembelajaran dan administrasi pendidikan di MTs Ubudiyah Pangkalan Berandan. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian deskriptif. Teknik pengumpulan data dilakukan melalui observasi, wawancara, dan dokumentasi. Subjek penelitian meliputi kepala madrasah, guru, siswa, serta mahasiswa PPL. Hasil penelitian menunjukkan bahwa mahasiswa PPL berperan aktif dalam kegiatan pembelajaran di kelas, membantu administrasi sekolah, mendukung kegiatan keagamaan dan ekstrakurikuler, serta berkontribusi dalam menciptakan lingkungan belajar yang lebih kondusif. Selain itu, keberadaan mahasiswa PPL memberikan dampak positif terhadap peningkatan motivasi belajar siswa dan efektivitas pelaksanaan kegiatan sekolah. Meskipun terdapat beberapa kendala seperti keterbatasan sarana dan perbedaan karakter siswa, mahasiswa mampu mengatasinya melalui koordinasi dengan guru dan penyesuaian strategi pembelajaran. Penelitian ini menyimpulkan bahwa program PPL memiliki peran strategis dalam mendukung manajemen dan proses pendidikan di madrasah serta menjadi sarana penting dalam pembentukan kompetensi profesional mahasiswa.
