Abstract

Monitoring volume material tambang memerlukan metode yang akurat, efisien, dan aman untuk mendukung kegiatan operasional. Berdasarkan kebutuhan tersebut, penelitian ini bertujuan untuk menganalisis tingkat akurasi geometrik dan volumetrik data Unmanned Aerial Vehicle-Light Detection and Ranging (UAV-LiDAR) terhadap Terrestrial Laser Scanner (TLS) sebagai referensi. Selain itu, penelitian ini juga bertujuan untuk menentukan konfigurasi parameter akuisisi dan pengolahan UAV-LiDAR yang menghasilkan akurasi geometrik dan volumetrik terbaik serta tidak berbeda secara signifikan terhadap TLS berdasarkan uji t dalam perhitungan volume material tambang. Penelitian dilakukan pada area stockpile seluas 9,860 ha dengan material tambang berupa batubara. Sebanyak 16 kombinasi skenario diuji, yang terdiri dari empat skenario akuisisi dan empat skenario pengolahan pada dua sesi akuisisi. Skenario akuisisi meliputi variasi ketinggian terbang 80 m dan 100 m dengan overlap 60% dan 80%, sedangkan skenario pengolahan meliputi variasi strip adjustment dan tie surface spacing 0,25 m dan 0,50 m. Uji akurasi geometrik dilakukan menggunakan titik Independent Check Point(ICP), sedangkan uji akurasi volumetrik dilakukan berdasarkan selisih volume terhadap TLS yang dilanjutkan dengan uji statistik paired sample t-test. Hasil penelitian menunjukkan bahwa seluruh kombinasi skenario memenuhi persyaratan ketelitian pemetaan tambang skala 1:1.000 Kelas 1 sesuai Keputusan Direktur Jenderal Mineral dan Batubara Kementerian ESDM Nomor 17 Tahun 2023 yang mengacu pada SNI 9135:2023, serta memenuhi toleransi akurasi volumetrik berdasarkan ASTM D6172-98. Konfigurasi terbaik diperoleh pada ketinggian terbang 80 m dengan overlap 80%, tanpa strip adjustment, dan tie surface spacing 0,50 m. Konfigurasi tersebut menghasilkan akurasi geometrik yang memenuhi standar yang ditetapkan serta menunjukkan hasil perhitungan volume yang tidak berbeda secara signifikan terhadap TLS berdasarkan uji paired sample t-test dengan nilai t-hitung sebesar -0,012 dan persentase selisih volume rata-rata sebesar 0,078%. Dengan demikian, konfigurasi tersebut direkomendasikan untuk monitoring volume material tambang karena mampu menghasilkan data yang akurat, konsisten terhadap TLS, dan efisien dalam pelaksanaannya.

Mining material volume monitoring requires methods that are accurate, efficient, and safe to support operational activities. Based on this requirement, this study aims to analyze the geometric and volumetric accuracy of Unmanned Aerial Vehicle–Light Detection and Ranging (UAV-LiDAR) data against Terrestrial Laser Scanner (TLS) data as the reference. In addition, this study aims to determine the UAV-LiDAR acquisition and processing parameter configuration that produces the best geometric and volumetric accuracy and is not significantly different from TLS based on a t-test in mining material volume calculation. The study was conducted in a coal stockpile area covering 9.860 ha. A total of 16 scenario combinations were tested, consisting of four acquisition scenarios and four processing scenarios across two acquisition sessions. The acquisition scenarios included flight altitude variations of 80 m and 100 m with overlap values of 60% and 80%, while the processing scenarios included variations in strip adjustment and tie surface spacing of 0.25 m and 0.50 m. Geometric accuracy testing was performed using Independent Check Points (ICP), whereas volumetric accuracy testing was conducted based on volume differences relative to TLS and followed by a paired sample it-test. The results indicate that all scenario combinations satisfied the accuracy requirements for Class 1 mapping at a scale of 1:1,000 in accordance with the Decree of the Director General of Mineral and Coal of the Ministry of Energy and Mineral Resources No. 17 of 2023, which refers to SNI 9135:2023, and also met the volumetric accuracy tolerance specified in ASTM D6172-98. The optimal configuration was obtained at a flight altitude of 80 m with 80% overlap, without strip adjustment, and with a tie surface spacing of 0.50 m. This configuration achieved geometric accuracy that complied with the established standards and produced volume calculation results that were not significantly different from TLS based on the paired sample t test, with a t-value of -0.012 and an average volume difference percentage of 0.078%. Therefore, this configuration is recommended for mining material volume monitoring because it provides accurate data, maintains consistency with TLS results, and can be implemented efficiently.
