Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

This study aims to determine the reliability level and the root cause of downtime and propose a preventive action to reduce heavy equipment downtime. The study method used in this study is a mixed-method. Using Minitab 17 software for reliability calculation and using Fishbone Diagram, 5-Whys Analysis, and Pareto Diagram for Root Cause Analysis. The result showed that heavy equipment is not in reliable condition. The output from Root Cause Analysis led that the system is the most influential factor with the highest percentage. Therefore, the company should do a corrective action and the planned preventive action based on the 5-Whys Analysis to reduce downtime
Concrete damage condition rating based on visual assessment is qualitative and subjective and depends on the investigator’s experience, knowledge, and skills, which results in varied assessments from each investigator. To resolve this problem, a condition rating scale of visual-based concrete damage assessment has been developed in order to show a measured condition and rate the concrete damage conditions of buildings. The scale can describe buildings that are in very good to very bad condition; a very bad rating means that the building cannot be used. This assessment also calculates the building structure element’s critical rating. The condition rating scale is determined based on the concrete’s damage condition and the concrete’s compressive strength requirements. Concrete damage-condition rating values are determined based on expert appraiser feedback that was obtained through a questionnaire, which was processed using the fuzzy logic approach. The condition rating scale usage of visual-based concrete damage assessment will show the building’s structural element damage condition rating and the building damage condition rating as a whole, as well as the actions that need to be taken. Assessment results can also show a priority scale to determine the next actions to be taken by the decision-maker.
