Abstract

This study critically assesses Precast Concrete (PC) quality compliance in Indonesian high-rise buildings by comparing material strength, geometric tolerances, and seismic connection performance against SNI requirements. Using five years of official inspection data (2020–2025) from 120 certified lots (BSN/PUPR), the analysis identifies recurring non-compliance, including a 15.0% compressive strength defect rate, 8.5% AOQ, and 17.1% reinforcement cover deficiencies that may compromise structural durability. Wet joints exhibit better seismic resilience (μ = 4.5) than dry joints (μ = 3.8), though dry joints show pinching effects that reduce energy dissipation.Key root causes include moisture instability, admixture dosing errors, and precision gaps, revealing a persistent mismatch between documented procedures and actual statistical quality control. The study recommends implementing automated QC systems and strengthening SNI certification through more rigorous statistical approaches. Future work should integrate machine-learning predictive models using real-time factory data to enhance defect prevention.

Abstract

This study tackles the persistent environmental and economic complexities associated with conventional concrete manufacturing by establishing a novel sustainable production framework. This framework strategically integrates geospatial data on local aggregate reserves with key regional economic variables, focusing specifically on West Java, South Sumatra, and South Sulawesi as representative study areas in Indonesia. Leveraging Geographic Information System (GIS) technology and official statistics from the Geospatial Information Agency (BIG), alongside regional economic indices from the Central Statistics Agency (BPS), the investigation meticulously analyzed the spatial arrangement of high-quality aggregates, material price fluctuations, and crucial logistics expenditures. A multiple linear regression model was employed for quantitative analysis, which decisively revealed that aggregate pricing (=0.62, p < 0.001) and logistics expenses (=0.31, p < 0.05) are the predominant cost drivers in sustainable concrete production, whereas aggregate technical quality contributes a smaller, measurable influence (=0.09, p > 0.05). The exceptional coefficient of determination (R2=0.89) substantiates the model's predictive power and its practical utility for cost management and optimization within eco-friendly concrete systems. Ultimately, this research emphasizes the critical necessity of converging environmental, technical, and economic data for effective resource stewardship. It also proposes future scholarly endeavors should focus on integrating real-time monitoring and advanced digital supply chain technologies to further bolster the sustainability credentials of the domestic construction industry.
