Abstract

Penelitian ini dilakukan untuk mengetahui pengaruh Inherent moisture (IM) dan Total moisture (TM) terhadap nilai kalori batubara pada stockpile PT. Berau coal Kecamatan Sambaliung Kabupaten Berau Kalimantan Timur. Penelitian ini dilakukan dengan menambahkan air sebanyak 10 mL dan 20 mL pada masing-masing sampel. Metode yang digunakan pada penelitian ini adalah metode kuantitatif dan deskriptif, yang jenisnya eskperimental untuk mendeskripsikan hasil dari percobaan secara objektif dan sistemastis. Metode kuantitatif digunakan dalam penyelesaian masalah dengan menggunakan data-data nilai sebagai bahan analisis guna menyelesaikan permasalahan terkait, dan metode deskriptif digunakan untuk menjelaskan secara spesifik hasil pengolahan data atau informasi yang diperoleh dengan menguraikan atau dengan rangkaian kata-kata. Hasil penelitian menunjukkan nilai IM 15,21% pada sampel 1 mempengaruhi nilai kalori sebesar 1.004 Kcal/kg, sampel 2 dengan nilai IM 14.92% mempengaruhi nilai kalori sebesar 982 Kcal/kg dan sampel 3 dengan IM 14,35% mempengaruhi nilai kalori sebesar 937 Kcal/kg. Nilai Tm 20,76% pada sampel 1 mempengaruhi nilai kalori sebesar 1.370 Kcal/kg, sampel 2 dengan nilai TM 21,20% mempengaruhi nili kalori 1.395 Kcal/kg dan pada sampel 3 nilai TM 22,08% mempengaruhi nili kalori 1.445 Kcal/kg. semakin tinggi nilai inherent moisture dan total moisture maka nilai kalori batubara akan semakin rendah, jika nilai inherent moisture dan total moisture rendah maka nilai kalori batubara akan semakin tinggi. Faktor-faktor yang menyebabkan tingginya nilai inherent moisture dan total moisture yaitu proses pencucian batubara dan ukuran butir tidak seragam.

Abstract

This research aims to make a technical design for mining in Pit B, an area planned by PT Indo Muro Kencana to be exploited based on the evaluation of economic ore reserves. Pit B is an area that has never experienced mining activities before. The mine design method involves a technical design process that considers geotechnical, topography, and reserve data aspects to determine an economical and technically feasible mining deadline. The purpose of this method is to produce an optimal and safe mining design, in order to maximize the extraction of mineral reserves by paying attention to work safety. The research method applied is quantitative, used to design pit and waste dump designs and calculate the difference in reserves between the researcher's design results and the company's pitshell data using surpac software. Descriptive analysis is carried out to explain the design process and calculation of the proposal. The pit geometry parameters include a level height of 15 meters, a level width of 5 meters, a slope of 60°, and a ramp width of 15 meters with a slope of 10%, according to the company's operational standards. The results of the calculation of the reserve volume showed that ore amounted to 326,809 tons and waste 4,911,173 tons. The reserve difference between the design and pitshell data is still within the company's tolerance limit of 33%, so this technical design is suitable as the basis for mining operations in the field.

Abstract

Research on the development of coal utilization for Indonesia is very important considering that Indonesia is a country that has large amounts of coal reserves, so it can use its coal not only as a source of energy for power plants but also needs to incentivize coal conversion for increased added value. To analyze the potential of using the early Eocene-Oligocene coal's formation in Tanjung Barito basin. In this study, data sources derived from laboratory test results will be analyzed by descriptive methods with quantitative approaches.  The results of this study were obtained through proximate tests on coal samples TIAN-0 1 and TIAN-0 2 total value moisture of 9.1 4% weight as-received basis (arb) and Moisture in the Analysis sample worth 3.67%, value ash content 7.35%, flying substance value 36.11%, tethered carbon value 52.86% with air-dried base (ADB) basis % weight and total sulfur value 0.36% with air-dried base (ADB) % weight. Based on the gross calorific value with an average caloric value of 7353 Kcal/kg, sample coal is classified as high volatile coal A bituminous. The results of testing on the potential of sample coal caking also indicate the potential utilization of Early Eocene-Oligocene coal Tanjung Formation to be used in the metallurgical industry with the results of testing the value of the Free Swelling Index sample showing the swelling ability of the coal with a value of 6 and 2.5 and G indexes 66 and 92.
