Abstract

Penelitian ini dilakukan untuk mengetahui konsentrasi kadar merkuri di perairan sungai (DAS) Desa Lamunga, Kecamatan Taliwang, Kabupaten Sumbawa Barat, Pronvinsi Nusa Tenggara Barat, Akibat proses Amalgamasi yang dilakukan oleh penambangan tanpa izin, untuk mendapatkan emas yaitu dengan cara amalgamasi. Tujuan penelitian ini adalah untuk menganalisis dan mendeskripsikan kadar pencemaran pada parameter pH, Total Suspended Solid (TSS), Total Dissolved Solid (TDS) dan Chemical Oxygen Demand (COD), pada air sungai. Pengambilan sampel air limbah berdasarkan metode purposive sampling. Hasil penelitian didapatkan bahwa nilai Pij untuk air sungai sampel A, termasuk dalam kondisi baik atau (memenuhi baku mutu),tetapi nilai COD pada titik A melibihi standar baku mutu pada kelas 3 dan 4, di sebabkan pembuangan air limbah pada titik B. sedangkan nilai Pij untuk air sungai sampel B melebihi standar baku mutu air sungai yang di tetapkan dan termasuk dalam tercemar sedang. dan untuk air sungai sampel C melebihi standar baku mutu air sungai yang di tetapkan dan termasuk dalam tercemar berat. Kualitas air sungai pada titik A hulu sungai memiliki kandungan Ph sebesar 7 mg/L, TSS sebesar 17,03 mg/L,TDS sebesar 0,07 mg/L, dan COD sebesar 50 mg/L. sedangkan Kualitas air sungai pada titik B tengah sungai memiliki kandungan Ph sebesar 8 mg/L ,TSS sebesar 3,18 mg/L, TDS sebesar 0,19 mg/L dan COD sebesar 60 mg/L. kemudian Kualitas air sungai pada titik C hilir sungai memiliki kandungan Ph sebesar 8 mg/L, TSS sebesar 5,88 mg/L, TDS sebesar 0,23 mg/L dan COD sebesar 50 mg/L.

Abstract

Asphalt is the main material in highway construction that plays an important role in determining the quality, durability, and comfort of road users. The demand for asphalt in Indonesia continues to increase in line with national infrastructure development, including in the West Nusa Tenggara region. PT Fima Kencana Kerthasari, located in Belo Village, Jereweh District, West Sumbawa Regency, is one of the companies engaged in the production of hot mix asphalt through a mixing plant facility. In practice, the production process often faces challenges in maintaining consistent asphalt quality due to variations in mixing temperature, inaccuracies in aggregate and asphalt measurements, and a lack of real-time process control. Considering the potential for quality improvement through the optimization of production process parameters such as temperature, mixing time, and aggregate-asphalt ratio, a systematic study at the PT Fima Kencana Kerthasari site is required. This optimization not only aims to meet technical specification standards (e.g., SNI 06-2489-1991 and SNI 7394:2008) but also to enhance the company's competitiveness through cost efficiency and operational efficiency.
