RISK OF BRIDGE CONSTRUCTION USING THE PROMETHEE METHOD IN PAPUA

Papuas topography is very diverse in the form of mountains, tropical rainforests. Papua has difficult access constraints and between regions that can only be reached by using air transportation modes, so Papua is in dire need of road and bridge infrastructure development so that community access in activities to meet needs and the transportation process from one location to another can run more smoothly. The research objectives are to identify risks to cost and time, analyze the dominant level of risk to cost and time in bridge construction. Data collection in the form of questionnaires and interviews were conducted at four construction service companies in Jayapura. Risk analysis is carried out by looking for values that represent respondents answers using the Sevirity Index (SI) method and the Risk Breakdown Structure (RBS) method to get the highest level of risk. Furthermore, analyze the risk using the (PROMETHEE) method to get the ranking of the most important risks.. So that nine indicators are obtained that affect cost performance with a high risk scale, namely culture and customs of the surrounding community, material price increases, material unavailability, delays in material delivery from suppliers, unstable soil conditions, delays in equipment delivery, design / specification changes, incomplete designs, disputes and claims. as a conclusion from the results obtained, it is found that the highest risk ranking for time and cost performance is the culture and customs of the surrounding community.
