Abstract : Sewage Treatment Plant (STP) Soekarno – Hatta Airport is equipment processing waste liquid at Soekarno – Hatta Airport. In the processing process waste the there is a decomposition process use aeration equipment and stabilization equipment. The impact of Covid-19 at Soekarno – Hatta Airport is experiencing decline passengers, based on BPS data in 2018 number passenger Soekarno – Hatta Airport departures reached 30,402,108 while in 2021 the number passenger only 8,557,607, this causes exists policy company that is exists efficiency budget at all line business company including existence efficiency budget maintenance equipment. From the data obtained happen decline The average performance value of STP equipment in 2020 was 96% down to 88.31% in 2022. For this reason, this research aims to find out Overall Equipment Effectiveness (OEE) value with count mark availability rate, performance rate, and quality rate of STP equipment, to find out the cause decreasing equipment performance value with know root problem the with using Fish Bone Diagram, 5 Whys Analysis, and 5W+1H to get reference in recommendation repair system maintenance on STP equipment. Recommendation repair the estimated capable increase the OEE value of STP equipment from the previous one in 2022 was 68 % to 79% in 2023.

Keywords : OEE, 5 Whys Analysis, STP.
