Introduction

Rancangan desain pit short term di pit panel ii pt. Karunia armada indonesia jobsite pt. Indonesia pratama, kecamatan tabang, kabupaten kutai kartanegara, provinsi kalimantan timur. Rancang desain pit jangka pendek batubara di Pit Panel II, Kutai Kartanegara, Kalimantan Timur. Evaluasi cadangan, produktivitas alat berat, dan desain menggunakan Minescape untuk target produksi.

Abstract

Tujuan penelitian adalah untuk mengetahui jumlah cadangan pada daerah penelitian, kemampuan produksi alat mekanis dan membuat desain pit jangka pendek. Evaluasi cadangan dan desain pit merupakan tahapan penting sebelum melakukan suatu penambangan. Pembuatan desain pit untuk mengetahui bentuk geometri penambangan atau lubang bukaan tambang untuk memperoleh cadangan batubara. Desain pit jangka pendek memberikan rencana penambangan secara bertahap sampai pada batas akhir penambangan. Penelitian ini dilakukan pada PT. Karunia Armada Indonesia Kecamatan Tabang Kabupaten Kutai Kartanegara Provinsi Kalimantan Timur. Penelitian dilakukan dengan memperhitungkan kemampuan alat dalam berproduksi untuk memcapai target yang di inginkan yang akan degunakan sebagai acuan dalam perencanaan (Desain) Pit untuk jangka pendek yaitu selama 1 (satu) bulan yakni pada bulan september 2023. Berdasarkan hasil penelitian, diperoleh jumlah cadangan batubara yang terdapat pada Pit Panel II KAI yaitu sebanyak 11.430.262 ton dengan overbarden sebanyak 41.952.366 BCM. Kemampuan Produktivitas alat muat mencapai 2.001.907 BCM/Bulan dan alat angkut 1.531.883 BCM/Bulan. Desain untuk jangka pendek yang dirancang menggunakan Sofware Minescape 5.7 dengan slope 60°, tinggi bench 10 meter dan offset (berm) 10 meter

Review

This paper presents a focused study on the short-term pit design for Panel II at PT. Karunia Armada Indonesia, located in Kutai Kartanegara, East Kalimantan. The primary objectives are clearly defined: to quantify coal reserves, assess mechanical equipment productivity, and subsequently develop a short-term pit design. The authors correctly identify the critical importance of reserve evaluation and pit design as foundational steps for any mining operation. By focusing on a specific, one-month operational window (September 2023), the study provides a practical and actionable plan for immediate mining activities, contributing directly to operational efficiency and resource extraction planning. The methodology employed in this research centers on integrating equipment production capabilities with geological data to generate a viable short-term design. The use of Minescape 5.7 software for pit design is a standard and appropriate choice for this type of geological and mining engineering analysis, ensuring the technical rigor of the design parameters. Key design specifications, such as a 60° slope, 10-meter bench height, and 10-meter berm, are explicitly stated, providing transparency for the proposed pit geometry. The results indicate significant coal reserves of 11,430,262 tons within Pit Panel II, alongside an overburden volume of 41,952,366 BCM. Productivity assessments show loading equipment capable of 2,001,907 BCM/month and hauling equipment at 1,531,883 BCM/month, offering crucial insights into the operational capacity for the targeted period. Overall, this paper delivers a concise and practical engineering solution for short-term mining operations. It successfully addresses its stated objectives by providing concrete figures for reserves, equipment performance, and a detailed pit design. While the study effectively outlines the technical aspects of the short-term plan, future research could enhance its scope by incorporating economic analyses, such as stripping ratios and production costs, to provide a more holistic operational outlook. Additionally, a discussion on the integration of this short-term design into a broader long-term mine plan would be beneficial. Nevertheless, for its immediate purpose, the paper offers a valuable contribution to the operational planning of the specific mining site.
