Abstract

Groundwater quality in coastal areas is responsive due to the interaction of fresh water with seawater. Groundwater quality monitoring studies in coastal area needs to be done regularly to prevent natural disasters and clean water crises in the future. In this study, measurements of groundwater physics parameter were carried out, i.e. electrical conductivity to analyze groundwater quality. The interpolation method based on Geographic Information Systems (GIS) was used to obtain values ​​between each sample point to produce a spatial distribution map of groundwater quality over the research location. The results of the study showed that groundwater quality in the coastal area of ​ Durung Village was generally still quite good with conductivity values ​​between 689 - 3,391 µS/cm. However, for the locations which is nearby the coast such as in the location of Malahayati Merchant Marine Polytechnic, it was indicated that it had been contaminated by seawater with the highest conductivity values between 5,763 – 6.270 µS/cm.

Abstract

Kawasan Gunung Kulu, Lhoong, Aceh Besar, sudah sering terjadi sering terjadi longsor baik itu longsoran tanah maupun jatuhan batu. Penelitian ini bertujuan untuk menganalisis data gaya berat di wilayah Gunung Kulu, Lhoong, Aceh Besar untuk mengidentifikasi sebaran anomali gaya berat yang berkaitan dengan potensi kerentanan longsor. Metode gaya berat digunakan untuk mendeteksi variasi densitas batuan bawah permukaan melalui pengukuran gravitasi observasi (gobs), perhitungan Free Air Anomaly (FAA), Simple Bouguer Anomaly (SBA), Anomali Bouger Lengkap (ABL). Nilai ABL yang diperoleh berkisar antara 71,5 mGal hingga 82 mGal, dengan nilai tinggi terdapat pada bagian barat hingga barat daya wilayah studi yang menunjukkan adanya batuan berdensitas tinggi seperti basalt , sedangkan nilai rendah pada bagian timur menunjukkan adanya zona berdensitas rendah yang berpotensi menjadi jalur longsor. Penelitian ini memiliki keterbatasan pada distribusi titik pengukuran gaya berat di lapangan, di mana terdapat area kosong pada bagian tengah wilayah studi akibat kondisi medan yang sulit diakses dan keterbatasan waktu survei. Hasil penelitian ini memberikan informasi awal kondisi bawah permukaan sebagai upaya mitigasi bencana longsor di wilayah penelitian serta menjadi referensi untuk studi lanjutan di bidang geologi teknik dan geofisika lingkungan.
