Abstract

Penelitian ini bertujuan untuk menentukan karateristik batubara pada Formasi Sembakung dengan metode pemetaan lapangan dan analisis kualitas batubara berupa analisis proksimat dan analisis nilai kalori. Hasil penelitian lapangan menemukan enam lapisan batubara pada Formasi Sembakung dengan ketebalan berkisar antara 0,92 meter s.d.1,40 meter. Kualitas batubara ditunjukkan oleh nilai rerata kelembaban 2,75 % (adb), kandungan zat terbang 20,96 % (adb), karbon tertambat 44,08 % (adb), kandungan abu 32,24 % (adb), sulfur total 6,27 % (adb). Nilai kalori berkisar antara 2.539 cal/gr s.d 6.212 cal/gr. Batubara termasukdalam jenis subbituminous sampai bituminuous (low volatile).

Abstract

The Subsurface coal resources are 43.533 billion tons with total reserves of 173.51 million tons. The Berau Regency area has coal-bearing formations of the bituminous - sub bituminous type, namely the Latih Formation, Labanan Formation, Domaring Formation, Sajau Formation and Sembakung Formation. The research methods used are surface geological mapping, rock sampling and drilling. The analysis used is coal quality and geological structure. The results of analysis of changes in the dip of rock layers caused by geological structures in the form of folds and thrust faults can cause changes in coal quality. The dip of coal seam in the LP 54 outcrop sample is 24º, which has lower coal quality compared to LP 38 that has a seam dip of 65º. The quality of coal in LP 38 seam position N 203º E/65º has a calorific value of 6,393 Kcal/kg, while in LP 54 seam position N 30º E/24º has a calorific value of 4,888 Kcal/kg. At the drill point, location MMA_19-T has better coal quality compared to MMA_18-T and MMA_20-T, this is because the seam in MMA_19-T experienced folding accompanied by faulting with a calorific value of 7326 Kcal/kg.

Abstract

Kabupaten Berau merupakan salah satu daerah sebagai Wilayah Izin Usaha Pertambangan sehingga dapat mempengaruhi kualitas air sungai. Air merupakan sumber daya alam yang diperlukan untuk hajat hidup orang banyak dan bahkan oleh semua makhluk hidup. Air sungai sangat bermanfaat terutama untuk masyarakat di wilayah pemukiman. Peran sungai memberikan sumber kehidupan bagi manusia, seperti pemanfaatan air dan kesuburan tanah disekitarnya. Tujuan penelitian ini adalah untuk mengetahui nilai parameter fisik, kimia dan mikrobiologi air intake Sungai Punan, air bersih (Water Treatment Plant) dan air minum (Reverse Osmosis) di lokasi penelitian. Metode penelitian yang dilakukan yaitu pengambilan sampel air intake Sungai Punan, air bersih untuk keperluan higiene sanitasi (Water Treatment Plant) dan air minum (Reverse Osmosis). Nilai rerata pH air intake Sungai Punan 7,8 dan air bersih 7,5 serta air minum 7,1. Nila rerata kekeruhan air bersih 14 NTU dan air minum < 0,01 NTU. Seluruh parameter fisik, kimia dan biologi pada air intake Sungai Punan, air bersih dan air minum berada pada nilai baku mutu yang dipersyaratkan. Proses Water Treatment Plant dan Reverse Osmosis dapat meniadakan bakteri Coliform dan E.Coli.

Abstract

The influence of the physical environment (family, school, community) in the development of students is very large, especially in the modern era like now with the virtual world environment. Where is this virtual environment a person can find out something outside of their existence. This paper is designed to find out how much influence the above environment has on the development of students in the perspective of Islamic education. In writing this paper using the library method by taking a variety of existing literature on google schooler. The results of the research from the preparation of this paper as a reference in educating students by following its development while maintaining Islamic values in its development in the world of education.

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 the calorific value of coal shows a negative linear correlation where the influence value for a 1% increase in Total Moisture is -71.343 kcal/kg and so is between Ash and the calorific value of coal 1% increase in Ash is -82.588 kcal/kg, which shows a negative linear correlation. 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.
