Abstract

Kegiatan praktik keinsinyuran ini bertujuan untuk mengaplikasikan hasil pembelajaran tentang aspek keinsinyuran dalam pelaksanaan pekerjaan analisis dan pemodelan data magnetotellurik (MT) dalam rangka mendelineasi sistem panas bumi di daerah Nage, Nusa Tenggara Timur. Metode magnetotellurik merupakan salah satu metode geofisika elektromagnetik yang memanfaatkan variasi alami medan listrik dan magnet bumi untuk mengidentifikasi distribusi resistivitas bawah permukaan. Analisis ini difokuskan pada penentuan model bawah permukaan, serta identifikasi zona prospek reservoar panas bumi. Dalam pelaksanaannya, kegiatan ini melibatkan tahapan pengambilan data, pengolahan, dan pemodelan inversi 3D. Hasil yang diharapkan adalah model resistivitas bawah permukaan yang mampu menggambarkan sistem panas bumi secara menyeluruh dan mendukung perencanaan eksplorasi lanjutan. Selain aspek teknis, praktik keinsinyuran ini juga menekankan penerapan prinsip-prinsip keinsinyuran yang meliputi etika profesi, tanggung jawab sosial dan lingkungan, serta penerapan aspek keselamatan dan kesehatan kerja (K3) dalam setiap tahapan kegiatan. Dengan demikian, praktik ini tidak hanya berkontribusi terhadap pengembangan teknologi eksplorasi geotermal di Indonesia, tetapi juga memperkuat kompetensi keinsinyuran yang berlandaskan profesionalisme dan integritas.

This engineering practice activity aims to apply the knowledge and principles of being a professional engineer in conducting the analysis and modeling of magnetotelluric (MT) data to delineate the geothermal system in the Nage area, East Nusa Tenggara. The magnetotelluric method is one of the electromagnetic geophysical techniques that utilizes natural variations in the Earth’s electric and magnetic fields to identify subsurface resistivity distribution. This analysis focuses on determining the subsurface model and identifying prospective geothermal reservoir zones. The activity involves several stages, including data acquisition, processing, and 3D inversion, also integrating geophysical interpretation with the available geological and geochemical data. The expected outcome is a subsurface resistivity model that effectively represents the overall geothermal system, supporting further exploration planning in the Nage area. In addition to technical aspects, this engineering practice emphasizes the implementation of engineering principles, including professional ethics, social and environmental responsibility, as well as the application of occupational safety and health (OSH) aspects in every stage of the activity. Thus, this practice not only contributes to the advancement of geothermal exploration technology in Indonesia but also strengthens engineering competencies founded on professionalism, ethics, and integrity.
