Abstract

The construction industry, particularly in housing development, plays a strategic role in meeting the need for adequate housing, supporting economic growth, and improving the quality of life for communities. However, the implementation of housing projects faces complex challenges, such as pressure to meet high quality standards, tight schedules, and limited budgets. Factors such as communication aspects and leadership competence play a significant role in decision-making to enhance project performance. This study aims to analyze various factors that influence the quality and performance of projects in housing development, including the influence of communication and leadership competence in decision-making to improve project performance. In addition, this research also evaluates the relationship between decision-making and project performance, as well as the mediating role of decision-making in the relationship between communication aspects and leadership competence on project performance. This study uses a quantitative approach with a survey method. Data were collected through a closed-ended questionnaire using a Likert scale and analyzed using statistics. The analysis includes descriptive analysis and PLS-SEM (Partial Least Squares Structural Equation Modeling), covering both the outer model and inner model measurements. The results of this study revealed a significant relationship between communication aspects and project leadership competencies on decision-making, as well as the impact of decision-making on overall project performance with a percentage of 73.6%. Furthermore, decision-making plays an important mediator in strengthening the relationship between the two variables of communication aspects and project leadership competencies with project performance with a percentage of 49.4%.

Abstract

The modernization of irrigation networks is a vital effort to improve the efficiency and effectiveness of water distribution for agriculture. This activity also represents the implementation of the government’s Asta Cita program in the context of national food security. One critical component of this process is excavation work, which significantly influences the success of such projects. This study aims to evaluate the accuracy of several interpolation methods in calculating excavation volumes based on design data, compared to existing conditions, using a tolerance threshold of 2.78%. The analysis indicates that interpolation methods produce varying results. The Kriging method shows a deviation of 2.30%, and the Surface to Surface (TIN) method shows a deviation of only 0.02%, both of which fall within acceptable deviation limits. These two methods also demonstrate high consistency and optimal accuracy for volume estimation. In contrast, methods such as Natural Neighbor (18.89%) and Radial Basis Function (RBF) (46.17%) result in significant deviations, indicating overestimation or underestimation that affects volume accuracy. Therefore, methods like Kriging and TIN, which meet the tolerance limits, are recommended for more accurate and efficient volume calculations in construction and topographic mapping activities.

Abstract

Dalam beberapa dekade terakhir, wilayah Daerah Aliran Sungai (DAS) Juwana di Jawa Tengah semakin sering dilanda banjir sehingga berdampak serius, mulai dari kerugian ekonomi hingga gangguan kesehatan pada masyarakat. Perubahan penggunaan lahan dan pengaruh perubahan iklim global diyakini menjadi pemicu utama perubahan pola curah hujan di wilayah ini. Penelitian ini dilakukan untuk memahami bagaimana dinamika curah hujan berkembang di DAS Juwana selama 22 tahun terakhir (1998–2019), serta bagaimana kondisi ini mungkin berubah hingga tahun 2080 berdasarkan dua skenario iklim yaitu pada kondisi RCP 4.5 dan RCP 8.5. Kami menggunakan metode downscaling statistik dengan data curah hujan satelit TRMM yang dikombinasikan dengan model iklim global CMIP5. Hasilnya menunjukkan bahwa DAS Juwana memiliki pola hujan tropis, dengan puncak curah hujan terjadi pada Desember hingga Februari. Beberapa tahun seperti 2006, 2008, dan 2010 mencatat hujan ekstrem yang bertepatan dengan fenomena La Niña. Proyeksi ke depan menunjukkan adanya tren peningkatan intensitas curah hujan, khususnya pada musim hujan. Di bawah skenario RCP 8.5, lonjakan curah hujan lebih tajam dibandingkan RCP 4.5, terutama pada Januari dan Desember. Temuan ini menjadi peringatan penting akan meningkatnya risiko banjir ekstrem di masa depan dan menegaskan perlunya strategi adaptasi serta perencanaan pengelolaan air yang lebih tanggap terhadap perubahan iklim masa depan.
