Penerapan Total Productive Maintenance pada Hydraulic Drilling Rig Zoomlion ZR60A-1 di PT Acset Indonusa Tbk

Abstract

Hydraulic Drilling Rig Zoomlion ZR160A-1 merupakan alat berat di PT Acset Indonusa Tbk yang mengalami tingkat downtime tertinggi sepanjang Januari–Juni 2024. Penelitian ini bertujuan untuk menganalisis penerapan Total Productive Maintenance dalam menurunkan downtime, meningkatkan keandalan alat, serta memperbaiki indikator produktivitas alat berat. Metode yang digunakan mencakup perhitungan MTBF, MTTR, PA, MA, dan EU. Hasil penelitian menunjukkan peningkatan nilai MTBF dan penurunan MTTR dari waktu ke waktu, serta capaian PA dan MA yang melampaui target perusahaan. Temuan penting lainnya meliputi perbaikan sistem pemeliharaan melalui digitalisasi form P2H dan Timesheet, serta pengembangan One Point Lesson (OPL) untuk edukasi teknis. Penerapan TPM juga diperkuat dengan implementasi budaya kerja 5S yang masih perlu ditingkatkan di lapangan. Secara keseluruhan, penerapan TPM terbukti mampu memberikan dampak positif terhadap penurunan waktu downtime.

The Zoomlion ZR160A-1 Hydraulic Drilling Rig is a heavy equipment unit at PT Acset Indonusa Tbk that recorded the highest downtime from January to June 2024. This study aims to analyze the implementation of Total Productive Maintenance in reducing downtime, improving equipment reliability, and enhancing heavy equipment productivity indicators. The methods used include calculations of MTBF, MTTR, PA, MA, and EU. The results show an increase in MTBF and a decrease in MTTR over time, with PA and MA exceeding the company’s target. Other key findings include improvements in the maintenance system through the digitalization of P2H and Timesheet forms, as well as the development of One Point Lessons (OPL) for technical education. TPM implementation is also supported by the application of the 5S work culture, which still requires further improvement on-site. Overall, TPM has been proven effective, with a positive contribution to reducing downtime duration.
