Fuzzy Logic Method to Manage the Risks of Oil and Gas Pipeline Projects to the Environment

Pipes are one of the supporting infrastructures that are needed in oil and gas projects. However, oil and gas pipeline construction projects have very complex risks and have a major impact on the environment. On the other hand, environmental factors are one of the risk factors for oil and gas pipeline projects with a value of 14% [2]. The existence of risk factors that are not managed properly will have a negative impact that accumulates and causes a hazard. Therefore, an affective risk analysis method is needed. The purpose of this study is to analyze the risks of oil and gas pipeline construction projects to the environment using the Fuzzy Logic method based on data obtained from questionnaires distributed to Oil and Gas Cooperation Contract Contractors operating in East Java - Indonesia. The results of the analysis show that of the 20 (twenty) risk factors, there are 2 risk factors that are at a high level, namely financial performance risk with a value of 14.9 and contractor experience risk with a risk value of 14.9 and the fuzzy logic method are considered to be used as an effective reference in decision making, this can be seen from the results of the calculation of the accuracy value which shows that the risk analysis system for the environment is accurate with an accuracy value of 0.90 which means the accuracy level is very high.
