Kehidupan masyarakat di Kabupaten Aceh Jaya wilayah barat tentu saja tidak jauh dari wilayah perairan estuari dikarenakan rata-rata masyarakat tersebut tinggal berdekatan langsung dengan perairan estuari. Pembuangan limbah kapal secara berlebihan dalam kegiatan penangkapan ikan di estuari Aceh Jaya wilayah barat tidak hanya mencemari perairan, namun juga mengganggu distribusi polutan yang berfluktuasi mengikuti siklus pasang surut, sehingga memicu perubahan signifikan pada kualitas air dan keseimbangan ekosistem estuari. Penelitian untuk menganalisis dan mengidentifikasi karakteristik estuari pada Kabupaten Aceh Jaya wilayah Barat dengan beberapa parameter untuk melihat karakteristik estuari ialah salinitas, Ph, suhu, TSS, pasang surut dan geomorfologi. Metode penentuan lokasi dengan menggunakan teknik Purposive Sampling dengan pengambilan data primer dan sekunder. Hasil yang diperoleh dari penelitian ini nilai salinitas tertinggi di sungai sebesar 0,3 ‰, di estuari sebesar 25 ‰, di laut sebesar 31 ‰, dan nilai salinitas terendah di sungai 0,2 ‰, di estuari sebesar 22 ‰, di laut sebesar 30 ‰. Sedangkan nilai pH tertinggi di sungai sebesar 6,7, di estuari sebesar 8,3, di laut sebesar 7,8, dan nilai pH terendah di sungai sebesar 6,1, di estuari sebesar 6,2, di laut sebesar 7,1. Nilai Total Suspended Solid (TSS) tertinggi berada dekat pesisir lokasi penelitian di wilayah aceh jaya bagian barat berkisar antara 200 mg/L – 1,200 mg/L, dan nilai Total Suspended Solid (TSS) terendah berada di sungai berkisar anatar 0 – 49 mg/L. Nilai Suhu tertinggi berada di Kuala Gampong Baro berkisar antara 28,6°C – 28,9°C, dan nilai Suhu terendah berada di Kuala Ujong Sudeung, Kuala Daya, Babah kuala, Kreung no, Keude unga dan Kuala ligan berkisar antara 28,2°C – 28,5°C. Nilai pasang tertinggi di wilayah aceh jaya bagian barat sebesar 0,4 m dan nilai surut terendah sebesar -0,3 m. Kondisi geomorfologi di wilayah aceh jaya bagian barat memiliki lebar estuari antara 24 m- 93 m, dengan jenis pasir halus dan kasar serta jenis vegetasi katang, pohon pinus, mangrove.

The lives of people in the western Aceh Jaya district are certainly not far from the estuary waters because the average community lives directly adjacent to the estuary waters. Excessive disposal of ship waste in fishing activities in the western Aceh Jaya estuary not only pollutes the waters, but also disrupts the distribution of pollutants that fluctuate with the tidal cycle, thus triggering significant changes in water quality and the balance of the estuary ecosystem. Research to analyze and identify the characteristics of the estuary in the Western Aceh Jaya Regency with several parameters to see the characteristics of the estuary are salinity, Ph, temperature, TSS, tides and geomorphology. The method of determining the location using Purposive Sampling technique with primary and secondary data collection. The results obtained from this study are the highest salinity value in the river of 0.3‰, in the estuary of 25‰, in the sea of 31‰, and the lowest salinity value in the river of 0.2‰, in the estuary of 22‰, in the sea of 30‰. While the highest pH value in the river was 6.7, in the estuary it was 8.3, at sea it was 7.8, and the lowest pH value in the river was 6.1, in the estuary it was 6.2, at sea it was 7.1. The highest Total Suspended Solid (TSS) values were near the coast of the study site in the western Aceh region ranging from 200 mg/L – 1,200 mg/L, and the lowest Total Suspended Solid (TSS) values were in the river ranging from 0 – 49 mg/L. The highest temperature values are in Kuala Gampong Baro ranging from 28.6°C – 28.9°C, and the lowest temperature values are in Kuala Ujong Sudeung, Kuala Daya, Babah Kuala, Kreung No, Keude Unga and Kuala Ligan ranging from 28, 2°C – 28.5°C. The highest tide value in the western part of Aceh is 0,4 m and the lowest low tide value is -0,3 m. Geomorphological conditions in the western Aceh region have an estuary width between 24 – 93 m, with fine and coarse sand types and vegetation types of katang, pine trees, mangroves.
