Evaluasi Daya Tampung Lingkungan Berdasarkan Parameter Beban Pencemar Di Hulu Kali Asem Bekasi

Abstract

Peningkatan aktivitas permukiman, industri, dan pengelolaan sampah di kawasan Bantargebang telah menurunkan kualitas air Hulu Kali Asem, Bekasi. Penelitian ini bertujuan menganalisis status mutu air dan mengevaluasi daya tampung beban pencemar sungai. Sampel diambil menggunakan metode purposive sampling dengan pendekatan grab sampling. Parameter yang dianalisis meliputi suhu, pH, BOD, COD, DO, dan Total Coliform. Status mutu air dianalisis menggunakan metode STORET berdasarkan PP Nomor 22 Tahun 2021. Hasil penelitian menunjukkan bahwa Hulu Kali Asem tergolong tercemar berat (STORET -42 hingga -34), dengan konsentrasi BOD, COD, dan Total Coliform yang melebihi baku mutu serta DO yang rendah. Nilai daya tampung yang negatif menunjukkan sungai telah mengalami overloaded, sehingga diperlukan pengendalian pencemaran dan pemantauan kualitas air secara berkelanjutan.

The increasing intensity of residential, industrial, and waste management activities in the Bantargebang area has degraded the water quality of the upstream Kali Asem River, Bekasi. This study aimed to assess water quality status and evaluate the river's pollution load carrying capacity. Water samples were collected using purposive sampling with a grab sampling approach. The analyzed parameters included temperature, pH, BOD, COD, DO, and Total Coliform. Water quality was assessed using the STORET method based on Government Regulation No. 22 of 2021. The results showed that the upstream Kali Asem was heavily polluted (STORET scores of -42 to -34), with BOD, COD, and Total Coliform exceeding water quality standards and low DO concentrations. Negative carrying capacity values indicated that the river was overloaded, highlighting the need for pollution control and continuous water quality monitoring.
