Abstract
This study examines the relationship between construction delays and project quality performance, exploring the role of quality standards and specifications as a mediating variable in the relationship between construction delays and project quality. The Structural Equation Modeling-Partial Least Squares (SEM-PLS) method is used to analyze complex relationships between variables that cannot be directly measured, with data collected through questionnaires distributed to relevant stakeholders. To identify the root causes, Root Cause Failure Analysis (RCFA) is applied, while Failure Mode and Effect Analysis (FMEA) is used to evaluate risks and provide improvement recommendations. The findings show that construction delays significantly affect project quality performance through quality standards and specifications as a mediator (p-value < 0.05). The RCFA analysis identifies the main causes of delays, including insufficient training, weak technical communication, and misalignment in specification changes. Meanwhile, FMEA results indicate that improvement strategies, such as budget automation, regular training, and periodic socialization, effectively reduce the Risk Priority Number (RPN) from the "high" category to "medium" or "low." This study emphasizes the importance of consistently implementing quality standards and systematically managing delay risks to enhance the efficiency and quality of construction projects in Indonesia. Keywords: Construction Delay, Project Quality, Specification Standards, SEM-PLS, RCFA, FMEA. Penelitian ini mengkaji hubungan antara keterlambatan konstruksi, dan kinerja mutu proyek, dengan mengeksplorasi peran standar kualitas dan spesifikasi sebagai variabel mediasi dalam hubungan keterlambatan konstruksi dan mutu proyek. Metode Structural Equation Modeling Partial Least Squares (SEM-PLS) digunakan untuk menganalisis hubungan kompleks antar variabel yang tidak dapat diukur secara langsung, dengan data yang dikumpulkan melalui kuesioner kepada stakeholder terkait. Untuk mengidentifikasi akar penyebab, digunakan Root Cause Failure Analysis (RCFA), sementara Failure Mode and Effect Analysis (FMEA) mengevaluasi risiko dan memberikan rekomendasi perbaikan. Hasil penelitian menunjukkan bahwa keterlambatan konstruksi berpengaruh signifikan terhadap kinerja mutu proyek melalui standar kualitas dan spesifikasi sebagai mediator. Analisis RCFA mengidentifikasi penyebab utama keterlambatan, termasuk kurangnya pelatihan, komunikasi teknis yang lemah, dan ketidakselarasan perubahan spesifikasi. Sementara itu, hasil FMEA menunjukkan bahwa strategi perbaikan seperti automasi anggaran, pelatihan rutin, dan sosialisasi berkala efektif menurunkan Risk Priority Number (RPN) dari kategori "tinggi" menjadi "sedang" atau "rendah". Penelitian ini menekankan pentingnya penerapan standar kualitas secara konsisten dan pengelolaan risiko keterlambatan yang sistematis untuk meningkatkan efisiensi dan mutu proyek konstruksi di Indonesia. Kata kunci: Keterlambatan Konstruksi, Kualitas Proyek, Standar Spesifikasi, SEM-PLS, RCFA, FMEA
