Identifying Saprolite Nickel in the Field in Indonesia Saprolite nickel ore plays a crucial role in the mining industry, especially for ferronickel and stainless steel production. In Indonesia, saprolite occurs widely in laterite nickel deposits. Therefore, accurate field identification helps geologists, engineers, and mining professionals conduct proper exploration, sampling, and utilization. What is Saprolite Nickel?

High-Grade vs Low-Grade Nickel Utilization in Indonesia Nickel plays a crucial role in Indonesia’s mining and industrial sectors. As the world’s largest nickel producer, Indonesia supplies both high-grade and low-grade nickel ores, each with distinct applications and economic importance. Understanding the differences between the two types of nickel is essential for evaluating their role in

GeoSynergy Solution Strengthens Collaboration at Geostructure 2025 The international seminar Geostructure 2025 officially took place in Bandung, West Java, bringing together leading experts, practitioners, and researchers in geotechnical and structural engineering from around the world. Under the theme “State-of-the-Art Monitoring for Forensic Investigations in Geotechnical and Structural Engineering”, the event became an important platform for

Freeport Underground Mine Accident Victims: Identities Confirmed The Freeport underground mine accident victims have been identified after a tragic incident at the Grasberg Block Cave (GBC) in Tembagapura, Mimika, Papua. A wet material slide trapped several workers in the underground mine. On Saturday, September 20, 2025, at 08:45 WIT, the rescue team of PT Freeport

The Use of Undisturbed Samples (UDS) in Numerical Modeling (PLAXIS, Geo5, MIDAS GTS) In geotechnical engineering, accurate data is the foundation of safe and reliable design. One of the most valuable sources of this data is the Undisturbed Sample (UDS)—a soil sample taken with minimal disturbance, preserving its natural structure, water content, and mechanical properties.

Understanding Job Safety Analysis (JSA) to Improve Workplace Safety Workplace safety is not just a legal requirement—it is the foundation of productivity, efficiency, and employee well-being. One of the most effective tools used worldwide to manage risks and prevent accidents is Job Safety Analysis (JSA). This method helps organizations systematically identify hazards, evaluate risks, and

Cyclic Simple Shear Test on Soils in Indonesian Mining Areas The Cyclic Simple Shear Test is one of the most reliable laboratory methods used to evaluate the cyclic behavior of soils under repeated loading conditions. In Indonesia, particularly in mining areas where ground stability is a major concern, this test provides crucial data to ensure

Permeability Test: Definition, Methods, and Applications in Geotechnical Engineering Permeability tests play a crucial role in geotechnical engineering. They show how easily water or other fluids can flow through soil or rock layers. Therefore, understanding soil permeability becomes essential for planning construction projects, designing foundations, evaluating groundwater flow, and preventing geotechnical failures. What is a

Underground Landslide at PT Freeport Indonesia: Seven Workers Initially Reported Trapped A landslide hit PT Freeport Indonesia’s (PTFI) underground mine in Mimika Regency, Central Papua, on Monday, September 8, 2025, at around 22:00 local time (WIT). Heavy rainfall triggered the incident. At first, seven underground workers were trapped, raising serious concerns about safety in the
