Abstract

http://dx.doi.org/10.17014/ijog.vol1no1.20065aThe Tigapuluh Mountain located in southeast corner of the Riau Province, is a part of the southern margin of the Central Sumatera Basin, one of the biggest hydrocarbon producing basin in Indonesia. The hydrocarbon source rock potential is a fine grained clastics within the Late Eocene Kelesa and Oligocene Lakat Formations. The Kelesa Formation source rock has a TOC value of 2.31–9.63%, with hydrocarbon content of a good to excellent categories (6.23–70.72 kg/ton rock), whereas the Lakat Formation has a TOC value of 0.67–3.46%, with hydrocarbon content of a poor to excellent categories (1.21–37.38 kg/ton rock). Source rock thermal maturation of the Kelesa Formation ranges from a late immature to early mature, with kerogen type of I and II, whereas the Lakat Formation ranges from a late immature, with kerogen type of I, II, and III. Diagenetic stage of the hydrocarbon source rock of the Kelesa Formation is included to Mudrock Stage II which is equivalent to a mesogenetic mature “A”. This diagenetic proccess was due to the burial history with the depth of up to 3000 m, resulted in a paleotemperature of 95C. The Lakat Formation is, however, included to Mudrock Stage I equivalent to the mesogenetic immature level. Burial history which occurred at the paleo temperature up to 65C, with the depth of burial up to 1500 m, led to the diagenetic process.

Abstract

Nikel adalah salah satu sumber daya mineral unggulan Indonesia dan merupakan logam yang berperan strategis dalam industri global. Studi ini bertujuan untuk membahas sejarah, kondisi terkini, serta proyeksi masa depan industri nikel di Indonesia. Terdapat dua tipe endapan nikel, yaitu sulfida dan laterit. Nikel di Indonesia didominasi oleh tipe laterit yang tersebar luas di Sulawesi, Halmahera, dan Papua. Eksplorasi nikel di bumi Nusantara telah dimulai sejak tahun 1901. Oost Borneo Maatschappij dan Bone Tole Maatschappij adalah perusahaan yang melakukan eksplorasi nikel ketika masa kolonial. Pasca kemerdekaan, PT INCO dan PT Aneka Tambang berperan penting dalam eksploitasi logam tersebut. Kebutuhan global untuk industri baja tahan karat dan baterai kendaraan listrik mendorong peningkatan produksi nikel Indonesia sejak tahun 2017. Pemerintah telah menerapkan kebijakan hilirisasi dan larangan ekspor bahan mentah untuk meningkatkan nilai tambah industri nikel domestik. Dengan cadangan nikel terbesar secara global, Indonesia berpeluang untuk menjadi pemain kunci industri nikel pada masa mendatang. Indonesia perlu mengoptimalkan pemanfaatan metal companions sambil terus mengontrol kemungkinan pencemaran lingkungan akibat industri pertambangan dan pengolahan nikel. Sinergi antara pemerintah, pelaku industri, dan masyarakat menjadi kunci keberhasilan pemanfaatan nikel Indonesia.

This study aims to discuss the history, current conditions, and future projections of the nickel industry in Indonesia. There are two types of nickel deposits: sulfide and laterite. Indonesia’s nickel is predominantly of the laterite type, which is widely distributed in Sulawesi, Halmahera, and Papua. Nickel exploration in the archipelago began in 1901. Oost Borneo Maatschappij and Bone Tole Maatschappij were companies conducting nickel exploration during the colonial era. After independence, PT INCO and PT Aneka Tambang played significant roles in the exploitation of the metal. The global demand for the stainless steel and electric vehicle battery industries has driven Indonesia’s nickel production growth since 2017. The government has implemented downstream processing policies and export bans on raw materials to increase the added value of the domestic nickel industry. With the world’s largest nickel reserves, Indonesia has the potential to become a key player in the nickel industry in the future. Indonesia needs to optimize the utilization of metal companions while continuously controlling the potential environmental pollution caused by nickel mining and processing industries. Synergy between the government, industry players, and the public is essential for the successful utilization of Indonesia’s nickel. Keywords: Nickel, Indonesia, laterite, metal companions, downstream
