Abstract

Current global economic conditions have made the coal prices become uncertain. PT Bukit Asam (PTBA) has taken corporate action by improving operational efficiency, cost control, develop coal diversification product and also optimizationin the mining operation. One of the operational efficiency programs for cost control in mining operation system is the Electrification Program. This program changed mining operations previously dominated by fuel-based mining system transformed into an electricity-based mining system for an electricshovel continue with the conventional truck. Implementation of Mining Systems with electric-based mining equipment divided into several stages for short-term and long-term targets. Electrification program consist of 7 Units Electric Shovel (PC3000-6E) and 40 Units Rigid DT (Belaz75135) with target20 Million BCM in 2017 located inBanko West Mine. PTBA through the electrification program has succeeded in reducing energy consumption by 333,861.74 GJoule/Years and reducing greenhouse gas emissions by 15,058.49 Ton CO2e/Year. Electrification program has successfully contributed for environmental sustainability by reducing energy consumption and greenhouse gas emissions in accordance with the vision of PTBA into a world-class energy company that cares about the environment.

Abstract

Arifiyanto B, Sindu RM.  2020. Reducing greenhouse gas emissions by implementing e-reporting system in PT Bukit Asam mining unit. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xxx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Coal mining activities are one of the activities that produce high greenhouse gas emissions. The purpose of this research is to calculate the success of reducing greenhouse gas emissions by implementing an E-Reporting System application in administrative reporting activities. This calculation uses a comparison basis before and after application of this technology with tier 2 emission factor approach according to the guidelines for the National Greenhouse Gas Inventory. E-Reporting System is one of the applications of the latest Industry 4.0 technology in the mining reporting system. This system succeeded in replacing previous system which was still conventional by eliminating use of operational vehicles for mining reporting. Through this program the company was able to save on fuel consumption and quantification of environmental improvements due to changes in this system succeeded in reducing greenhouse gas emissions by 3,355 tCO2e per year. Implementation of the E-Reporting System application can reduce GHG emissions generated in mining operations.
