Abstract

Seiring dengan pertumbuhan Indonesia, bertumbuh pula infrastrukturnya, dan dengan tumbuhnya infrastruktur tersebut muncullah permintaan akan bahan bangunan, termasuk didalamnya batu andesit, untuk memenuhi permintaan tersebut ada beberapa tambang yang menambang dan mengolah batu tersebut, salah satunya adalah PT. Alfa Granitama, tugas akhir ini akan berfokus pada perawatan salah satu sistem crusher yang dimiliki oleh PT. Alfa Granitama, khususnya sistem crusher alfa 6. Crusher alfa 6 saat ini beroperasi di bawah target produktivitas yang ditetapkan oleh perusahaan, tugas akhir ini bertujuan untuk meringankan masalah tersebut dengan mengusulkan peningkatan ketersediaan crusher alfa 6 dengan meminimalkan waktu henti yang disebabkan oleh masalah pemeliharaan. Meningkatkan ketersediaan crusher alfa 6 diharapkan akan meningkatkan jumlah batu yang dapat diproses oleh perusahaan, untuk mengurangi waktu henti yang disebabkan oleh pemeliharaan, tesis ini akan menggunakan metode Reliability Centered Maintenance 2 (RCM 2) dengan harapan dapat meningkatkan keandalan unit penghancur batu alfa 6, penulis juga akan melihat ketersediaan saat ini dan menggunakan alat lain seperti diagram pareto untuk memberikan gambaran yang lebih jelas dan menggunakan temuan penelitian untuk memberikan saran perbaikan.

As Indonesia grow, so does its infrastructure, and with the infrastructure grows come demand for construction materials not least of which is andesite stone, in order to fulfill this demand there are quarries that mine and process such stone, one of them is PT. Alfa Granitama, this thesis will focus on the maintenance of one of the crusher system owned by PT. Alfa Granitama, specifically the alfa 6 crusher system. The alfa 6 crusher is currently operating under the productivity target set by the company, this thesis aim to alleviate the issue by proposing to increase the availability of the alfa 6 crusher by minimizing the downtime caused by maintenance issues. Increasing the availability of the alfa 6 crusher would increase the amount of stone that could be processed by the company, in order to reduce the downtime caused by maintenance this thesis will use Reliability Centered Maintenance 2 (RCM 2) method in hopes of improving the reliability of Alfa 6 stone crusher unit, the author will also look at the current availability and use other tools such as pareto diagram to give a clearer picture and use the findings to give improvement suggestions.
