Effectiveness of Soetta Airport STP Performance

In the last five years, Soekarno-Hatta International Airport's operating efficiency (OEE) has significantly improved from 59.7% in 2019 to 92.3% in 2024. Initially, the COVID-19 pandemic in 2020 adversely affected STP's performance—OEE fell to 59.7% as a result of airport closures and a significant reduction in passenger traffic. The volume of waste decreased by 13%, necessitating operational reductions. Nonetheless, following 2021, recovery commenced as aviation transport returned to normalcy. Two principal initiatives propelled the increase in efficiency: firstly, the execution of preventative maintenance, which diminished downtime (2023–2024); secondly, the optimization of biological processes, including enhanced aeration, leading to a consistent effluent quality above 95%. By 2024, the STP approached full capacity, with a mere 7.7% deficit. The volume of waste increased by 15% from 2022 to 2023 due to a resurgence in airport traffic, achieving peak efficiency of 94.7% in 2023. Despite compliance with quality standards typically exceeding 80%, problems persist, including changes in COD/BOD during peak seasons and the maintenance of TSS filters. To attain the 95% compliance objective, investment in technology and the development of human resources are essential, drawing insights from the resilience demonstrated during the COVID crisis.
