Abstract

The rapid advancement of artificial intelligence (AI) has opened new opportunities for developing hydrological models that are more adaptive, accurate, and efficient. This study aims to examine the research trends and directions concerning the application of AI in hydrological modeling using bibliometric analysis. A total of 136 relevant articles published between 2015 and 2025 were retrieved from the Semantic Scholar database using the Publish or Perish software. These records were then analyzed with VOSviewer to map keyword relationships and identify current research focuses. The results reveal a consistent upward trend in AI-based hydrological modeling publications, particularly since 2020. Among the top 15 cited articles, a total of 2,316 citations were recorded, averaging 17.03 citations per article. Keywords such as “LSTM,” “RNN,” “streamflow,” and “hydrological forecasting” appeared with the highest frequency and recentness, signifying a shift toward more adaptive and predictive modeling approaches. Furthermore, density visualization highlights a strong focus on deep learning models particularly LSTM and Support Vector Machines while showing opportunities for further exploration in hybrid models and climate resilience applications. Although limited to a single database, the study provides a methodologically robust overview of the current research landscape. The findings underscore the transformative role of AI, not merely as a computational tool, but as a key enabler for designing hydrological models that are data-driven, responsive, and capable of supporting sustainable water resource management in the face of environmental uncertaintie.

Abstract

Sektor konstruksi di Indonesia menghadapi tantangan serius terkait Keselamatan dan Kesehatan Kerja (K3), dengan kontribusi signifikan terhadap total kecelakaan kerja nasional. Pekerjaan struktur atas di gedung tingkat tinggi memiliki risiko tinggi karena kompleksitasnya. Penelitian ini bertujuan untuk mengidentifikasi, menilai, dan mengendalikan risiko kecelakaan kerja pada pekerjaan struktur atas di Proyek Pembangunan Learning Center Bank Tabungan Negara Dago Pakar, Bandung. Studi ini menggunakan metode deskriptif kuantitatif dengan pendekatan Analisis Identifikasi Bahaya, Penilaian Risiko, Penentuan Pengendalian Risiko, dan Peluang (IBPRP), sesuai dengan Permen PUPR No. 10 Tahun 2021. Data primer diperoleh melalui wawancara dengan responden ahli dan pekerja, serta data sekunder dari studi literatur dan dokumen proyek. Hasil menunjukkan 21 aktivitas pekerjaan struktur atas, dengan 50 variabel risiko tergolong tinggi dan 48 sedang. Pengendalian risiko awal meliputi rekayasa teknis (pengamanan), administrasi (SOP, pelatihan, inspeksi), dan penggunaan Alat Pelindung Diri (APD) seperti helm, sepatu, sarung tangan, dan body harness. Penelitian ini menegaskan pentingnya IBPRP untuk mengelola risiko konstruksi. Disarankan studi lebih lanjut untuk mengeksplorasi variabel risiko spesifik, peran pekerja di K3, dan meningkatkan pengawasan terhadap pekerja.Kata Kunci: Analisis Risiko, Kecelakaan Kerja, IBPRP, Keselamatan Konstruksi

Abstract

The selection of scaffolding type is a crucial aspect in construction project execution, as it significantly affects time effectiveness and cost efficiency. This study aims to analyze the cost and time associated with the use of scaffolding and Perth Construction Hire (PCH) in the construction project of the IME Building at Jenderal Soedirman University (UNSOED), and to compare both methods in order to determine the most optimal alternative. The research employs a descriptive quantitative approach, conducted through observation and the collection of secondary data, including detailed engineering design (DED) drawings, Unit Price Analysis (AHSP), and price lists for scaffolding and PCH. The collected data were analyzed to calculate the time productivity and cost of each scaffolding method. The results indicate that PCH is more effective in terms of time, offering a saving of approximately 4 days or 20% compared to scaffolding. However, in terms of cost, scaffolding is more efficient, as the cost of using PCH is approximately 24% higher. Therefore, it can be concluded that PCH excels in time effectiveness, while scaffolding is more suitable for cost efficiency in the execution of this project.

Abstract

In project implementation, both owners and contractors place great emphasis on timely completion. However, project delays often occur, necessitating an effective time performance analysis method to minimize the risk of delays. Therefore, a project time performance analysis was conducted by comparing actual field data with the initial plan. This study used a quantitative descriptive approach by analyzing variables from field observation data. The project was scheduled for completion on December 30, 2025, with a duration of 514 calendar days. The analysis was conducted in the 35th and 48th weeks of project implementation. The results in the 35th week showed a slower project completion prediction, namely around February 22, 2026. However, in the 48th week, the project was estimated to be completed earlier, namely on December 27, 2025, where the contractor could save 0.37% of the overall progress of the plan that had been implemented.
