Abstract

Pada penelitian ini, dilakukan analisis penyebab dan dampak serta tindakan mitigasi yang dapat dilakukan untuk menghindari juga mengurangi dampak keterlambatan proyek pembangunan dermaga yang dibuat oleh PT. XYZ. Metode yang digunakan untuk analisis penyebab yakni Fault Tree Analysis, dan untuk menganalisis dampak digunakan Event Tree Analysis. Terakhir, upaya untuk menghindari penyebab dan mengurangi dampak dianalisis menggunakan Bow Tie Analysis. Hasil menunjukkan bahwa faktor utama penyebab keterlambatan yakni kendala pada tahap eksekusi proyek, dengan minimal cut set pada pengadaan material terlambat dengan probabilitas sebesar 0.0102574. Ada pula faktor sistem manajemen yang kurang baik, dengan minimal cut set kurangnya koordinasi antar pekerja dengan probabilitas sebesar 0.0063485. Ditemukan pula besar denda sebagai dampak keterlambatan yang berkisar antara Rp30.298.269 (selama satu hari) hingga lebih dari Rp5.453.688.503 (selama lebih dari 6 bulan). Terakhir, dicari pula recovery barrier untuk masing-masing threat dan consequence, lalu dilanjutkan dengan pencarian escalation factor dan mitigation escalation, dalam rangka memitigasi kemungkinan-kemungkinan terburuk.

In this study, a cause-and-impact analysis was carried out to derive mitigation measures to avoid and reduce the impact of delays in the dock construction project conducted by PT. XYZ. The method used for causal analysis was Fault Tree Analysis, and for impact analysis, Event Tree Analysis was carried out. Finally, efforts to avoid causes and reduce impacts are out-lined by using Bow Tie Analysis. The results show that the main factor causing delays is the difficulties at the project execution stage, with a minimum cut set on delays of material procure-ment with a probability of 0.0102574. There also exists the factor of poor management system, with a minimum cut set of a lack of coordination between workers with a probability of 0.0063485. It was also found that fines (as a delay conse-quence) ranged from IDR 30,298,269 (for one day) to more than IDR 5,453,688,503 (for more than 6 months). Subse-quently, we also discovered recovery barriers for each threat and consequence, before proceeding with pinpointing escala-tion factors and mitigation escalations in order to mitigate the worst possibilities.
