Penelitian ini dilatarbelakangi oleh fenomena ketidaksesuaian kualifikasi personel kontraktor yang berisiko menurunkan efektivitas tim pada proyek konstruksi. Fokus studi mencakup evaluasi kesesuaian personel, analisis dampaknya terhadap kinerja, serta perumusan strategi peningkatan performa tim. Menggunakan rumus Slovin, terpilih 33 proyek di Kabupaten Badung sebagai sampel. Metodologi yang diterapkan adalah deskriptif kuantitatif untuk persentase kesesuaian, regresi linier berganda untuk menguji pengaruh variabel, dan Focus Group Discussion (FGD) untuk menyusun langkah strategis.Hasil penelitian mengungkap bahwa indikator kompetensi memiliki tingkat kesesuaian terendah dibandingkan pendidikan dan pengalaman. Secara kolektif, ketiga variabel tersebut berkontribusi signifikan sebesar 67,5% terhadap kinerja tim, dengan kompetensi sebagai faktor dominan. Strategi perbaikan yang direkomendasikan meliputi peningkatan kesadaran dan akses sertifikasi, pemberian apresiasi bagi tenaga ahli bersertifikat, pelatihan berkelanjutan, program magang, serta penguatan soliditas tim melalui kegiatan nonformal.

The construction sector faces a dual challenge of high carbon emissions and resource depletion, amidst an urgent municipal solid waste crisis in Indonesia. While incineration has been implemented to reduce waste volume, it produces Incineration Bottom Ash and Fly Ash (IBA/IFA) that remains largely underutilized. This study aims to evaluate the potential of Incineration Ash as an eco-friendly construction material and to formulate strategic policy recommendations to support the vision of zero waste and a circular economy. Utilizing a narrative review method of 20 strategic literatures (2015–2025), the research finds that incineration ash possesses superior pozzolanic characteristics, capable of producing construction materials with compressive strengths up to 17 MPa while reducing CO₂ emissions by 14.60% to 22.63%. However, industrial-scale implementation is hindered by a "Regulatory Paradox," where ash is technically proven safe through encapsulation but remains legally classified as hazardous waste (B3) under Government Regulation No. 22/2021. The study formulates three transformative policy recommendations: (1) Reclassifying treated incineration ash as non-hazardous building material post-TCLP testing; (2) Issuing specific national technical standards (SNI) for ash-based materials; and (3) Stimulating market demand through Green Public Procurement. This research concludes that synchronizing environmental regulations with technical infrastructure standards is the key to transforming waste burdens into sustainable construction resources in Indonesia.

The maintenance of the Ayung River aims not only to maintain the cleanliness and smooth flow of the river itself, but also as part of a broader environmental conservation effort to create a more environmentally friendly and sustainable city. This study aims to identify and assess risks in the implementation of the Tukad Ayung river maintenance project, determine dominant risks and their acceptance levels, and formulate appropriate mitigation and risk ownership strategies to minimize potential impacts on project cost, time, and quality. The study employed a mixed-method approach combining qualitative risk identification with quantitative risk assessment using probability-impact analysis based on ISO 31000:2018. Brainstorming and questionnaires were selected as data collection techniques, with 26 respondents selected using purposive sampling. The results identified 15 valid risks consisting of 9 unacceptable risks (60%) and 6 undesirable risks (40%). The dominant risk was tidal seawater conditions in downstream areas, which obtained the highest probability-impact score of 25 and was categorized as an unacceptable risk requiring immediate mitigation measures. The mitigation strategies implemented included risk reduction, risk transfer, and risk avoidance approaches. Mitigation for this dominant risk involves obtaining tidal seawater level data from Benoa Harbor to optimize downstream work scheduling and implementing a combination of concrete culvert and cyclope concrete foundations to enhance structural resistance in estuary areas. The largest allocation of risk ownership is assigned to the contractor, covering 8 identified risks. The findings contribute to improving risk mitigation planning and decision-making for urban river maintenance projects in Indonesia.
