Abstract

During a move to the new drilling location, two braces of the upper mast section on a 550 HP oil and gas rig was damaged. When damage is discovered, the rig operating company should conduct a risk analysis related to the damage using the standard used to determine rejection criteria and follow-up repairs. The strength of the rig mast is calculated using Finite Element Analysis (FEA) with initial conditions (before damage occurs) where all braces are installed and extreme conditions where neither brace is repaired. The calculation results are then used to assess the risk of reducing the rig mast strength. The results of the integrity analysis will show FEA of rig mast and the distribution pattern of stress ratio values, which is the ratio between the stress that arises and the allowable stress of the material on the mast parts due to loading.

Abstract

The purpose of this research is to produce a WEB-based learning e-module using Google Classroom that is valid, practical, and effective in Electrical Engineering Drawing subjects. WEB-based learning e-modules using Google Classroom are designed to improve student understanding to improve student learning outcomes. This research method uses Research and Development (R&D) with 4-D development procedures (Define, Design, Develop, Dissemination). The data analysis technique used descriptive analysis techniques to describe the validity, practicality, and effectiveness of WEB-based learning e-modules using Google Classroom. The results obtained from this development research: The validity of the WEB-based learning e-module using Google Classroom is declared valid on the media and material aspects. The practicality of WEB-based learning e-modules using Google Classroom from teacher and student responses is stated to be very practical. The effectiveness of WEB-based learning e-modules using Google Classroom is declared effective in improving learning outcomes. Based on the findings of this study, it was concluded that the WEB-based learning e-module using Google Classroom was declared valid, practical, and effective to be used as a learning aid in Electrical Engineering Drawing subjects.
