| dc.description.abstract | Batubara merupakan salah satu sumber daya alam yang melimpah di Sumatra dan Kalimantan. Penelitian ini bertujuan untuk menentukan pengaruh parameter kandungan air bawaan, kadar abu, dan total sulfur terhadap nilai kalori batubara dari Sumatera Barat, serta mengetahui kualitas batubara Sumatera Barat berdasarkan nilai kalori batubara. Penelitian ini menggunakan metode standar American Society for Testing and Materials (ASTM) dengan sampel dari dua daerah di Sumatera Barat. Uji kadar air, abu, dan total sulfur dilakukan menggunakan standar ASTM D3173/D3173M-17a, ASTM D3174-12(2018), dan ASTM D4239-18, sedangkan nilai kalori diukur dengan bom kalorimeter berdasarkan ASTM D5865/D5865M-19. Hasil menunjukkan bahwa kandungan air bawaan dan kadar abu berbanding terbalik dengan nilai kalori, sementara total sulfur berbanding lurus dengan nilai kalori. Nilai kalori batubara dapat diprediksi menggunakan parameter-parameter ini. Batubara Sumatera Barat termasuk kategori subbituminous, dengan sampel dari daerah B memiliki nilai kalori lebih tinggi dibandingkan dengan daerah A, menunjukkan kualitas batubara daerah B lebih baik. | |
| dc.description.abstract | Coal is one of the abundant natural resources in Sumatra and Kalimantan. This study aims to determine the effect of inherent moisture, ash content, and total sulfur parameters on the calorific value of coal from West Sumatra, as well as to determine the quality of West Sumatra coal based on coal calorific value. This research uses the American Society for Testing and Materials (ASTM) standard method with samples from two areas in West Sumatra. Moisture, ash and total sulphur tests were conducted using ASTM D3173/D3173M-17a, ASTM D3174-12 (2018) and ASTM D4239-18 standards, while calorific value was measured with a bomb calorimeter based on ASTM D5865/D5865M-19. Results shown that inherent moisture and ash content are inversely proportional to calorific value, while total sulphur is directly proportional to calorific value. The calorific value of coal can be predicted using these parameters. West Sumatra coal belongs to the subbituminous category, with samples from region B having a higher calorific value compared to region A, indicating the better quality of region B coal. | |
