Journal KURVATEKKURVATEK Abstract

Coal quality is one of the key factors in determining the effectiveness of processing and utilization. Coal quality assessment involves analyzing physical and chemical aspects to determine its characteristics. Coal quality is also influenced by geological conditions at the mining site, which affect the quality and amount of carbon in the coal. To ensure consistency, it is necessary to implement coal quality control based on physical and chemical parameters from the mining process in the pit to storage in the stockpile. Analysis of the effect of total moisture and ash on the calorific value of coal is the purpose of this study. The method used is a ROM (Run of Mine) coal sample located at the stockpile location. The relationship between Total Moisture and Ash to the calorific value of coal shows a negative linear correlation. This means that every 1% increase in Total Moisture results in a decrease in calorific value of 71.343 kcal/kg and likewise every 1% increase in Ash value results in a decrease in calorific value of 82.588 kcal/kg. Total Moisture increases by 1%, reducing the calorific value of coal by 71 kcal/kg, and increasing Ash content by 1% reduces the calorific value of coal by 83 kcal/kg.

Conclusion

Total Moisture and Ash significantly affect the calorific value of coal.Higher Total Moisture and Ash content lead to a lower calorific value.Specifically, a 1% increase in Total Moisture reduces the calorific value by 71 kcal/kg, while a 1% increase in Ash content reduces it by 83 kcal/kg.

Future Research

Penelitian lebih lanjut perlu dilakukan untuk memahami secara komprehensif faktor-faktor lain yang memengaruhi kualitas batubara di Formasi Labanan, seperti pengaruh jenis batuan induk dan kondisi paleoekologi pengendapan. Hal ini dapat dilakukan dengan analisis petrografi batubara yang lebih detail dan rekonstruksi lingkungan pengendapan batubara. Selain itu, studi tentang efektivitas berbagai metode penanganan batubara untuk meminimalkan peningkatan kadar air dan abu selama proses penambangan dan penyimpanan juga sangat penting. Penelitian ini dapat menguji perbandingan penggunaan penutup (cover) pada tumpukan batubara dengan metode pengeringan batubara sebelum penyimpanan. Terakhir, pengembangan model prediksi kualitas batubara berdasarkan data geokimia dan geofisika dapat membantu mengoptimalkan eksplorasi dan eksploitasi batubara di Sub-Cekungan Berau, sehingga dapat meningkatkan efisiensi dan keberlanjutan industri batubara.
