Abstract

Penelitian ini memetakan potensi panas bumi di Kabupaten Kutai Kartanegara untuk mendukung transisi energi bersih menggunakan teknologi binary cycle. Dengan metode remote sensing, analisis citra satelit Landsat 8 OLI/TIRS dilakukan untuk menghitung Normalized Difference Vegetation Index (NDVI) dan Land Surface Temperature (LST), serta menggunakan peta geologi untuk identifikasi sesar. Data ini dianalisis dengan metode Analytical Hierarchy Process (AHP) untuk menentukan wilayah potensial. Hasil menunjukkan bahwa wilayah dengan kerapatan vegetasi rendah dan suhu permukaan tinggi, khususnya di sekitar sesar aktif, memiliki potensi panas bumi yang signifikan. Desa Tamapole dan Muara Jawa Ulu diidentifikasi sebagai lokasi optimal untuk pembangunan pembangkit listrik tenaga panas bumi berbasis binary cycle. Berdasarkan penelitian ini, disimpulkan bahwa implementasi teknologi binary cycle di wilayah ini berpotensi mendukung target keberlanjutan Ibu Kota Nusantara dengan menyediakan energi panas bumi yang ramah lingkungan.

Abstract

One of the problems encountered in geothermal exploitation activities is Silica Scaling Rate (SSR). Addressing SSR remains a significant problem, especially during production in geothermal fields with high Silica Saturation Index (SSI). High SSI can lead to silica deposition in pipes. Silica deposition occurs due to temperature drops, pressure decreases, and pH increases. As the temperature drops, the SSR increases, disrupting the fluid flow process from the reservoir. To address this issue, a system was designed to monitor the pipe's condition and trigger SLS injection if the temperature parameter value dropped. SLS functioned by binding silica particles in the fluid, preventing silica from adhering to the pipe walls. This process was carried out by adding SLS chemicals to the fluid flow through the pipes. SLS materials had the ability to bind silica and effectively prevent scale formation. Based on analysis and calculations, a temperature drop was directly proportional to an increase in SSI. A reference temperature of 95°C was used as an indicator for SLS injection because SSI > 1 at this temperature. A dose of 50 ppm SLS was shown to effectively reduce SSI up to 50%, preventing silica scaling in geothermal pipes. This study demonstrates the effectiveness of SLS as a mitigation strategy for silica scaling, offering a cost-efficient and less disruptive solution compared to conventional pipe cutting methods.
