Abstract
Usaha pertambangan di Indonesia, khususnya pada sektor batubara mengalami beberapa hambatan terkait dengan fluktuasi Harga Batubara Acuan (HBA), serta regulasi pemerintah yang sebenarnya baik untuk keberlanjutan usaha pertambangan di Indonesia. Namun, dengan regulasi tersebut juga menekan profit dari stakeholder (kontraktor, pemilik Izin Usaha Pertambangan (IUP), dan broker) usaha tambang batubara. Sehingga, efisiensi dan Optimalisasi proses pertambangan perlu digalakkan agar profit loss dapat ditutupi dengan efisiensi biaya produksi batubara. Maka dari itu, penelitian ini berusaha mengoptimalkan penjadwalan produksi pada PT. X agar biaya-biaya produksi seperti bahan bakar, manhour, dan lain sebagainya dapat ditekan. Biaya-biaya yang ada pada proses bisnis kontraktor tambang batubara nantinya akan dihitung berdasarkan nilai sekarang untuk memberikan gambaran yang lebih baik untuk PT. X terkait profit dari bisnisnya. Penelitian ini juga mengakomodasi beberapa parameter penting bagi proses penambangan seperti kemiringan lereng, frekuensi hujan wilayah, maupun kondisi aktual di lapangan yang harapannya dapat membuat model optimisasi menjadi lebih representatif untuk diimplementasikan di lapangan.

Mining businesses in Indonesia, particularly in the coal sector, experience several obstacles related to fluctuations in the Coal Reference Price (HBA), as well as government regulations which are actually good for the sustainability of the mining business in Indonesia. However, this regulation also suppresses profits of stakeholders (contractors, Mining Business License (IUP) owners, and brokers) in the coal mining business. Thus, efficiency and optimization of the mining process need to be encouraged so that profit loss can be covered by cost efficiency of coal production. Therefore, this study seeks to optimize production scheduling at PT. X so that production costs such as fuel, manhour, and so on can be reduced. The costs that exist in the coal mining contractor business process will later be calculated based on the present value to provide a better picture for PT. X about its profit from the business. This study also accommodates several important parameters for the mining process such as slope, regional rainfall frequency, and actual conditions in the field which are expected to make the optimization model more representative to be implemented in the field.
