Abstract

Proyek konstruksi Light Rail Transit (LRT) merupakan proyek infrastruktur strategis untuk mendukung mobilitas perkotaan, namun pelaksanaannya menghadapi berbagai risiko yang dapat memengaruhi kinerja proyek. Penelitian ini menganalisis manajemen risiko pada proyek Light Rail Transit (LRT) menggunakan metode Failure Mode and Effect Analysis (FMEA). Melalui kuesioner, wawancara pakar, dan diagram fishbone, teridentifikasi 35 faktor risiko valid. Analisis dilakukan dengan mengukur nilai Risk Priority Number (RPN) berdasarkan tingkat keparahan, frekuensi, dan kemampuan deteksi. Hasil penelitian menunjukkan nilai RPN rata-rata sebesar 257,17, dengan lima risiko dominan (RPN 343–448) yang diidentifikasi melalui prinsip Pareto. Risiko utama tersebut meliputi perubahan desain, kemacetan lalu lintas area proyek, ketidaksesuaian spesifikasi teknis, ketidaksinkronan perencanaan (Struktur/Arsitektur/MEP), serta keterbatasan tenaga ahli. Temuan ini mengonfirmasi bahwa ±80% permasalahan proyek dipicu oleh 20% faktor risiko utama. Strategi mitigasi direkomendasikan melalui penguatan koordinasi teknis, digitalisasi desain, dan peningkatan kompetensi SDM untuk meminimalisir kegagalan konstruksi.

Abstract

Precast façade systems are increasingly used in high-rise construction, but their effectiveness depends on the synchronization of material delivery, lifting, work-front readiness, and installation activities. This study aims to identify construction waste and workflow inefficiencies in precast façade installation using a macro-level Value Stream Mapping (VSM) approach. A quantitative descriptive case study was conducted on a high-rise apartment project in Jakarta, Indonesia, involving 33 construction professionals. Data were collected through structured questionnaires, site observations, and project documentation. The results show that 258 of 523 planned façade panels were installed, representing an overall achievement of 49.33%, while the mean achievement across Floors 8–12 was 50.70%. Waiting and inventory were the most dominant wastes, both with a mean score of 4.42, followed by overproduction and overprocessing with scores of 4.36. The macro-level VSM indicates that these wastes are associated with synchronization problems among material delivery, temporary storage, lifting availability, and installation readiness. A Future-State VSM is therefore proposed based on pull-based material delivery, Just-in-Time logistics, lookahead planning, and direct-to-install lifting. Although the proposed configuration has not been empirically validated, it provides a practical framework for reducing non-value-adding activities and improving workflow coordination in precast façade installation.
