Abstract

PT Triaryani adalah perusahaan tambang batubara dengan cadangan besar yang membutuhkan kualitas batubara terjaga untuk memenuhi permintaan konsumen. Kualitas batubara cenderung berubah setelah berpindah tempat, sehingga dilakukan analisis perubahan nilai parameter antara front penambangan dan stockpile. Analisis ini bertujuan mengetahui pengaruh parameter kualitas batubara terhadap nilai kalori dan menentukan parameter paling signifikan. Hasil analisis membantu pengendalian perubahan parameter kualitas lebih mudah dilakukan. Sampel batubara diuji di laboratorium untuk menghasilkan nilai parameter kualitas, seperti total moisture, ash content, volatile matter, total sulfur, dan caloric value. Data dianalisis menggunakan SPSS dengan metode regresi linear berganda, menghasilkan persamaan: CV = 6165,457 – 59,212TM – 64,971AC + 9,36VM - 2,662TS. Setiap kenaikan 1% pada total moisture, ash content, dan total sulfur menyebabkan penurunan kalori sebesar 59,212 Kcal/kg (ar), 64,971 Kcal/kg (ar), dan 2,662 Kcal/kg (ar). Volatile matter berpengaruh positif, setiap kenaikan 1% menyebabkan kenaikan kalori 9,360 Kcal. Parameter paling besar pengaruhnya adalah total moisture dan ash content. Pengendalian kualitas batubara di lapangan dilakukan dengan selective mining, pengaturan aliran air, kontrol penggunaan bahan kimia, pembersihan alat, penerapan aturan FIFO pada stockpile, penggunaan excavator backhoe untuk memisahkan batubara yang terbakar, serta penyiraman jalan secara rutin.
