Analisis Pengukuran Relative Importance Index (Rii) Untuk Menentukan Peringkat Faktor Penyebab Keterlambatan Pekerjaan Kanopi Proyek East Connection Taxiway Bandara Soekarno-Hatta

Abstract

The Soekarno-Hatta International Airport is a very busy international airport that requires development to enhance its capacity. The development undertaken involves the taxiway infrastructure. In the East Connection Taxiway Phase I Project at Soekarno-Hatta Airport, an aircraft bridge was constructed above the highway connecting the north and south runways. To mitigate the impact of jet blasts and aircraft engine noise pollution on road users, a canopy with a steel structure was constructed. The project faced delays during implementation, necessitating the identification of the causes of these delays as well as an assessment of their relevance. As a result, the purpose of this study is to calculate the Relative Importance Index (RII) and rank the causes driving project delays. Design Planning (X1), Materials (X2), Labor (X3), Equipment (X4), Financial Conditions (X5), Design Changes (X6), Schedule and Construction Supervision (X7), and Environmental and Social Factors (X8) are among the variables investigated. A quantitative survey with descriptive analysis was used as the research approach. Financial Conditions (X5) is ranked highest with a RII value of 0.864, and Schedule and Construction Supervision (X7) is placed last with a RII value of 0.750, according to the data. This study is planned to serve as a reference for future canopy installations on taxiways that straddle public roadways.
