Abstract

Penelitian ini membandingkan kualitas air laut di Dermaga Pantai Penganak, Kabupaten Bangka Barat, Kepulauan Bangka Belitung pada tahun 2023 dan 2024. Kajian ini dilakukan untuk mengetahui dampak aktivitas penambangan timah laut terhadap parameter fisika dan kimia air laut. Pengambilan sampel dilakukan di beberapa titik dengan parameter utama yang dianalisis meliputi TSS, pH, salinity, kadar amonia (NH₃-N) dan sulfida (H2S), kadar logam berat (Hg, Pb, Cd, Cu, dan Zn) serta beberapa parameter lainnya. Hasil penelitian menunjukkan adanya fluktuasi kualitas air antara kedua tahun tersebut, dengan peningkatan kadar logam berat di beberapa titik yang diduga berasal dari aktivitas pertambangan. Meskipun sebagian besar parameter masih berada dalam batas baku mutu yang ditetapkan, terdapat indikasi penurunan kualitas air laut yang perlu menjadi perhatian. Oleh karena itu, diperlukan pengelolaan lingkungan yang lebih ketat serta upaya mitigasi untuk mengurangi dampak pencemaran akibat aktivitas pertambangan di wilayah tersebut.

Abstract

Abstract Ogan Ilir Regency is included in the development program as a buffer zone for Palembang City, which is part of the Sriwijaya Megaregion, due to its distance of approximately 35 km. Ogan Ilir Regency has established a Spatial Planning (RTRW) Plan for 2023–2024. This RTRW serves as the basis for policy direction and the development of urban areas. Therefore, research on spatial analysis is necessary to evaluate existing development. This study uses descriptive analysis with a spatial approach, namely a Geographic Information System (GIS). The software used is QGIS, which is open-source. The data sources include Sentinel satellite imagery and the Spatial Planning Map of Ogan Ilir Regency. The analysis applies supervised classification to identify existing land use. The results show that 11,461.4 hectares of land use are not in accordance with the Ogan Ilir RTRW. The largest area of inconsistency is found in North Indralaya District, which is planned as an urban area but is still predominantly used for oil palm agricultural land.
