The 2018 Palu Earthquake stands as one of Indonesia’s most devastating natural disasters. On September 28, 2018, a magnitude 7.5 earthquake struck Central Sulawesi. Soon after, a massive tsunami and soil liquefaction followed, destroying large parts of Palu, Donggala, and nearby regions. Causes of the Palu Earthquake The disaster occurred due to movement along the […]
Geotechnical engineering plays a crucial role in coal mining projects across Indonesia and worldwide. From ensuring slope stability to managing groundwater and designing safe foundations, geotechnical expertise helps reduce risks and optimize mining operations. This article explores the major challenges faced by geotechnical engineers in coal mining and the solutions that make operations safer, more
Soil investigation plays a vital role in geotechnical engineering, construction, and mining projects. One of the most important decisions in this process is selecting the right drilling method — Wet Drilling vs Dry Drilling. Each method has unique advantages and limitations depending on project requirements, soil conditions, and environmental factors. According to the International Society
A waterwell is an engineered structure designed to access groundwater from an aquifer through drilling or excavation. People use the extracted water for many purposes, including household needs, agriculture, industry, and commercial activities. Depending on the aquifer depth and water demand, waterwells can be categorized as shallow wells or deep wells. Functions of a Waterwell
In construction, mining, and geotechnical engineering, drilling plays a vital role in exploring underground conditions and obtaining soil or rock samples. The process helps engineers determine material properties, identify potential risks, and design safe and efficient structures. Based on the medium and technique used, drilling is generally divided into two main types: wet drilling and
Drilling is one of the main methods in soil investigation to determine subsurface conditions. Through this process, engineers collect essential data such as soil types, layer strength, and samples of soil or rock for laboratory testing. In practice, two drilling techniques are commonly applied: wet drilling and dry drilling. Understanding the differences between these two
Geotechnical drilling is a crucial part of soil and rock investigation for construction projects such as buildings, bridges, dams, and roads. One of the most important components in this process is the drill bit, which serves as the cutting tool that penetrates soil and rock layers. Choosing the right type of geotechnical drilling bit is
In construction planning, the foundation plays a critical role in ensuring both safety and efficiency. A strong foundation supports structural loads and minimizes settlement that could otherwise damage the building. To achieve this, engineers rely on soil investigations. One of the most widely applied field methods in geotechnical engineering is the Standard Penetration Test (SPT).
Triaxial Cyclic Test in Indonesia is an essential laboratory method in geotechnical engineering used to analyze the dynamic properties of soil. This test evaluates soil response to cyclic loading caused by earthquakes, traffic vibrations, or industrial machinery. By conducting this test, engineers can design safer and more resilient foundations, embankments, and infrastructure projects in one
Geotechnical engineering is a branch of civil engineering that studies the physical and mechanical properties of soil and rock to ensure the stability and safety of construction projects. This field plays a critical role in the planning, design, and execution stages of infrastructure development such as buildings, bridges, dams, ports, and mining projects. The Role
