Abstract

This study examines the proportional distribution of human resource (HR) and material costs in building construction projects, using the Rectorate Building construction at Nurul Hasan University as a case study. Efficient cost allocation is a critical component of construction project management, as imbalances between labor and material expenditures can lead to budget overruns, schedule delays, and compromised quality. Employing a quantitative descriptive approach, this research analyzes official project documents, including the Bill of Quantities (BoQ) and standardized unit price analyses, to determine the relative contributions of HR and material costs across major work categories. The findings indicate that material expenditures significantly dominate project spending, accounting for 80% of the total direct cost, while HR costs represent only 20%. Work categories such as reinforced concrete, masonry, roofing, and carpentry demonstrate strong material dependency due to the high cost of construction materials such as steel, cement, aggregates, timber, and prefabricated components. In contrast, preparatory and early-stage works show a higher proportion of labor costs, reflecting their reliance on manual activities. The study also evaluates indirect costs and contractor profit margins, revealing that non-resource expenditures constitute 10% of the total project value, and the contractor’s profit margin stands at 9.1%, both of which fall within acceptable industry standards. These results highlight that while material management plays a decisive role in cost efficiency, effective labor allocation and supervision remain essential for ensuring construction quality. Overall, the research offers valuable insights for practitioners seeking to improve cost control strategies in medium-scale building construction projects.

Abstract

This study aims to identify educational supervision principles that can be adopted by practitioners to address the specific needs and challenges of educational institutions and to enhance educational quality sustainably. The study employed a Systematic Literature Review (SLR) using the PRISMA approach. Eighteen articles met the inclusion criteria and were analyzed, while 306 were excluded. The review identified 15 key principles of educational supervision: collaborative, democratic, needs-based, adaptive, sustainable, participatory, scientific, continuous improvement-oriented, supportive, evaluative, humanistic, innovative, flexible, professional development-oriented, and accountable. Their application varies according to contextual challenges such as limited teacher competence, geographical constraints, inadequate facilities, and diverse socio-cultural backgrounds. In institutions with limited training access, needs-based and collaborative supervision effectively supports teacher development through mentoring and peer learning communities. In remote schools, adaptive and flexible supervision can be implemented through online platforms for observation and feedback. The findings indicate that effective supervision requires contextual sensitivity, flexibility, strategic use of digital technologies, and trust-based professional relationships. The study proposes three theoretical frameworks: (1) the context-sensitive supervisory innovation rule, emphasizing alignment between management practices and institutional readiness; (2) the digital relational supervision theory, integrating data-driven technologies with collaborative and humanistic relationships; and (3) the sustainable supervisory learning theory, conceptualizing supervision as a continuous cycle linking evaluation, reflection, and professional development to promote long-term improvement in teaching and learning across diverse contexts.
