Abstract

The estimation of project costs and completion timelines are crucial aspects that need to be accurately predicted, as they are key indicators of a project's success. Issues like cost overruns and delays in project completion have become common in the construction industry. PT XYZ, a mining construction company, encountered a cost overrun in May 2023, leading to a 21.6% increase in the budget. According to the initial project baseline, it was expected to be completed by September 2023, but faced an 8-month delay. This study aims to explore the external factors causing cost and time overruns, identify the most significant factors, and propose recommendations to reduce these issues. The research methods used are Decision Making Trial and Evaluation Laboratory (DEMATEL) and Analytical Network Process (ANP) to examine the relationship between the factors and determine the most dominant one. Data was collected through questionnaires, and a threshold was set via a Focus Group Discussion (FGD) with experienced professionals in construction who played a key role in project decisions. The DEMATEL analysis, with a threshold of 0.5000, produced a relationship diagram of the criteria, and the ANP analysis, conducted using SuperDecisions software, revealed that the most influential factor affecting cost and time overruns is the accuracy of the Scope of Work (SOW) . As a result, it is recommended that PT XYZ improve project management and ensure higher accuracy in defining the SOW for future projects

Abstract

Land cover dynamics in a small island can be determined using Geographic Information System (GIS) approach based on multitemporal image analysis. This study aimed to classify major land cover types and to map land cover changes of Bawean Island. Two sets of 10 meter resolution satellite data ALOS AVNIR (2010) and Sentinel-2A (2020) were used in this study. Satellite image analysis was carried out through several stages namely image pre-processing including radiometric and geometric correction, supervised image classification and accuracy test. Image classification results from 2010 to 2020 showed a significant change in land cover on Bawean Island. The forest vegetation land cover declined significantly from 13,470.5 Ha in 2010 to 8,543.4 Ha in 2020. Most of the area have been converted into paddy fields and built-up areas. The accuracy test and validation were determined by comparing the 2020 Sentinel image classification results with field observation conducted in 2021. The analysis showed good results with 82.52% overall accuracy and 79.66 Kappa coefficient. Further investigation found that changes in land cover on Bawean Island occured due to the agriculture and infrastucture development.

Abstract

Salah satu metode untuk mendapatkan gelombang yang relatif tenang pada daerah pelabuhan adalah dengan menggunakan breakwater sebagai peredam energi gelombang. Pada artikel ini akan dilakukan analisis hidrodinamika dan sistem tambat struktur floating breakwater yang akan digunakan di Pelabuhan Tanjung Emas Semarang dengan metode numerik. Analisis hidrodinamika yang akan diperhitungkan adalah redaman gelombang yang terjadi dengan variasi layout, periode gelombang, dan tinggi gelombang. Sedangkan analisis sistem tambat yang akan diperhitungkan adalah tension tali tambat dengan variasi diameter dan panjang tali tambat. Dari analisis hidrodinamika yang telah dilakukan, didapat bahwa layout dengan penempatan breakwater secara tertutup mempunyai hasil yang paling baik dalam meredam energi gelombang di area Pelabuhan Tanjung Emas Semarang. Pada pemodelan tersebut, tinggi gelombang dengan arah dominan barat laut yang terjadi di area pelabuhan berkisar antara 0.803 – 1.073 m. Sedangkan dengan arah dominan timur, tinggi gelombang yang terjadi di area pelabuhan berkisar 0.292 - 0.414 m. Pada analisis konfigurasi sistem tambat, tali tambat yang direkomendasikan adalah tali tambat dengan ukuran diameter 19 mm dengan panjang 18 m. Tension terbesar yang terjadi pada struktur breakwater dengan lebar 10 meter sebesar 119.94 kN dengan safety factor 2.79. Sedangkan struktur breakwater dengan lebar 6 m memiliki tension terbesar yaitu 94.82 kN dengan safety factor 3.53.

Abstract

This study compares the Payback Framework and the Governance, Risk Management, and Compliance (GRC) framework as evaluation tools for research funding programs. The Payback Framework, developed in 1994 by Buxton and Hanney, focuses on assessing the impact of health research, encompassing knowledge creation, policy influence, and economic benefits. On the other hand, the GRC framework emphasizes risk management, governance, and regulatory compliance, ensuring that programs are managed effectively within regulatory boundaries. This comparative analysis highlights the strengths and weaknesses of both frameworks, examining their applicability to different types of programs. The Payback Framework is well-suited for research programs that require long-term impact assessment, particularly in healthcare and social sciences. Meanwhile, the GRC framework is more appropriate for sectors with stringent compliance requirements, such as finance and healthcare. This study provides insights into the choice of evaluation frameworks based on program objectives, organizational needs, and available resources..
