Abstract

Tujuan dari penelitian ini adalah untuk mengetahui hasil analisis proksimate, uji kuat tekan dan penyalaan api serta laju pembakaran pada briket. Hasil penelitian menunjukkan bahwa jenis perekat dan biomassa berpengaruh nyata terhadap kadar air, kadar abu, zat mudah menguap, karbo tertambat, penyalaan api serta laju pembakaran, sedangkan tidak berpengaruh terhadap kerapatan dan kuat tekan. Perlakuan terbaik yang sesuai dengan standar SNI dari penelitian ini didapatkan dari perlakuan dengan komposisi 60% batubara : 40% arang sengon dan 50% batubara : 50% arang sengon dengan kode sampel KH dan KP perekat tepung tapioka. Briket dengan komposisi 60%batubara : 40% arang sengon kode sampel KH (Pulaubalang) yang dihasilkan dari perlakuan ini memiliki nilai kadar air 5,99 % ; kadar abu 6,92 % ; zat terbang 11,42%; kadar karbon tertambat 75,65%; laju pembakaran 3,74 g/menit ; nyala api 6 : 36 menit ; kerapatan 0,23 g/cm3 ; kuat tekan 38,22 kg/cm2. Briket dengan komposisi 50%batubara : 50% arang sengon kode sampel KP (Balikpapan) yang dihasilkan dari perlakuan ini memiliki nilai kadar air 6,96 % ; kadar abu 4,73 % ; zat terbang 11,92%; kadar karbon tertambat 76,39%; laju pembakaran 2,61 g/menit ; nyala api 6 : 57 menit ; kerapatan 0,21 g/cm3 ; kuat tekan 24.70 kg/cm2.

Abstract

Mining design is part of the planning stages of mining as a very important factor is determined before the actual mining plan begins. CV. Kutai Kumala Energy is a company engaged in coal mining which has a Mining Business License located in Loa Kulu District, Kutai Kartanegara Regency, East Kalimantan Province. On CV. Kutai Kumala Energy pit BC was calculated with the aim of meeting the overburden of 5,095,565.38 BCM and the coal stripping target of 673,541.31 MT. In determining production targets for 1 year and in accordance with the capabilities of the tools at the research location.

Abstract

Composites are a combination of two or more different materials and their properties to form new materials that have better characteristics. The composite was previously composed of activated claystone, activated zeolite, and coconut shell activated charcoal with 3 ratios, namely: (claystone [C] : zeolite [Z] : activated charcoal [A] = 60:20:20; 20:20:60; and 20:60:20. This composite acts as an adsorbent in the adsorption process of acid mine water samples. Based on the results of the adsorption test, it was concluded that the composite cannot neutralize the pH of acid mine water. Of the three types of composites, Composite A (claystone [C] : zeolite [Z] : activated charcoal [A] = 60:20:20) showed a significant influence with a decrease in the concentration of heavy metals Iron and Manganese within 30 min of contact time. Fe adsorption capacity is 20,7 mg/g and Mn is 24,3 mg/g.
