Abstract

Indonesia menduduki peringkat pertama sebagai produsen nikel terbesar di dunia. Meningkatnya kebutuhan nikel secara global dalam pengembangan mobil listrik memberikan dampak positif terhadap industri tambang nikel di Indonesia. Hal tersebut berkaitan dengan pemanfaatan nikel sebagai komponen baterai mobil listrik. Lebih dari itu, Indonesia merupakan negara dengan cadangan bijih nikel terbesar di dunia (sekitar 32,7%). Pada tahun 2019, ESDM mencatat produksi nikel Indonesia mencapai 800 ribu ton. Dalam kegiatan penambangan, biaya (cost) menjadi komponen penting untuk mencapai titik optimal fungsi keuntungan (profit). Biaya penambangan per ton (unit-cost) dapat digunakan sebagai parameter untuk menentukan tingkat efisiensi dari suatu kegiatan penambangan. Akan tetapi, masih banyak ditemui berbagai permasalahan terkait formulasi unit-cost yang tidak seragam antara satu perusahaan dengan perusahaan lainnya. Maka dari itu, penelitian ini akan mengkaji estimasi unit-cost dengan dua pendekatan yaitu comparative dan statistics. Berdasarkan penelitian ini, didapatkan nilai unit-cost yang berkisar antara US$9,97/ton hingga US$18,23/ton menggunakan comparative approach. Rekomendasi yang diberikan yaitu menggunakan metode rasio pembanding, dengan beberapa variabel berupa gaji, total biaya penambangan (total cost), dan produksi per tahun. Sementara, statistical approach menghasilkan formulasi unit-cost .

Abstract

Corona Virus Disease (COVID-19) pandemic dramatically impacted the energy sector. About 4.5% of global primary energy consumption dropped in 2020, where coal demand decreased by 220 million tons of coal equivalent. The drop was driven by lower electricity demand due to policies against Covid-19 (i.e., travel restriction, lockdown, and new standard). In particular, the COVID-19 crisis has already created profound uncertainties for the Indonesian coal mining industry as one of the world's largest coal producers and exporters. Coal is the primary energy source for Indonesian electricity, contributing to the national revenues. A debate about action to take, whether to focus on dealing with Covid-19 health or maintaining economic growth, is unavoidable. With the number of cases continuing to rise, we set out to investigate the impact of COVID-19 on Indonesia's coal mining industry. Rapid desk assessment and descriptive statistical approach were used in this study by evaluating secondary data during the pandemic, comparing with previous years before the COVID-19 pandemic. The results revealed a tangible transformation in coal demand, production, and price. Despite domestic coal consumption for power generation decreased, the coal price increased in mid of 2021 due to rising coal demand in China.
