  Final Year Student

  Calculated the bearing capacity of soil for the planned construction of the Ampel Bridge in Pekalongan, Central Java. During the data collection process, I employed three comparative methods: SPT testing, Cone Penetration Testing (CPT), and Core Drilling to determine the physical parameters (bulk density, specific gravity) and mechanical properties (cohesion, internal friction angle) of the soil. The results yielded three bearing capacity values that can be used for the load foundation of the bridge with a pile foundation type. Show less

  Kementerian Kelautan dan Perikanan Republik Indonesia

  Feb 2020 - Feb 2021

  Geotechnical Engineer

  Calculated the bearing capacity of soil for the planned construction of the Cold Storage facility for the Ministry of Maritime Affairs and Fisheries at Selat Lampa Port, Riau Islands. During the data collection process, I used several comparative methods, including SPT testing, Cone Penetration Testing (CPT), Core Drilling, and Geoelectric testing. The three primary methods (CPT, SPT, and Core Drilling) were used to calculate the bearing capacity, while Geoelectric testing confirmed the lateral and vertical distribution of soil and rock layers to determine the basement depth.

  PT Tectona Mitra Utama

  Dec 2023 - Mar 2025

  Geotechnical Engineer

  Evaluated the slope stability of the hauling road bench at the nickel mine experiencing landslides at the SCM site in Konawe, Southeast Sulawesi. During the data collection process, I employed several methods, including geological mapping, SPT, core drilling (geotechnical description of soil and rock), UDS sampling, UCS, PLT, and failing head permeability testing. Geological mapping was used to analyze the geological structure and stratigraphy, as well as the slope and landslide conditions. Core drilling was conducted to provide descriptions of the soil and rock. UDS, UCS, and PLT samples were taken for testing the physical and mechanical properties of the soil/rock. The permeability test was performed to monitor groundwater movement that could affect slope stability. Show less
