Daftar Isi:
- Sungai Musi merupakan sungai terbesar dan terpanjang di Sumatra Selatan. Berkembangnya kegiatan penduduk di Daerah Aliran Sungai (DAS) Musi dapat berpengaruh terhadap kualitas air sungai dan dapat menyebabkan terjadinya pencemaran. Tingginya aktivitas industri maupun rumah tangga di sepanjang Sungai Musi menyebabkan menurunnya kualitas lingkungan di DAS Musi. Berdasarkan hal tersebut, maka perlu dilakukan penelitian lebih lanjut untuk mengetahui seberapa besar tingkat pencemaran yang terjadi di DAS Musi. Tujuan dari penelitian ini adalah untuk mengkaji dan mengetahui tingkat saprobitas di sepanjang DAS Musi bagian hilir berdasarkan nilai SI (Saprobik Indeks), serta mengetahui tingkat pencemaran air menggunakan penilaian saprobitas perairan. Penelitian ini menggunakan plankton sebagai bioindikator pencemaran organik perairan. Penelitian ini menggunakan rancangan eksplorasi dengan metode survei, dan penetapan stasiun pengambilan sampel dengan metode purposive sampling. Hasil penelitian menunjukkan kelimpahan fitoplankton di perairan Sungai Musi pada rentang 123-2581 sel/liter atau rata-rata sebesar 1397 sel/liter. Indeks Saprobik di perairan Sungai Musi berkisar antara 0,63-1, digolongkan pada fasesaprobik, yaitu β-Mesosaprobik, sehingga pada perairan Sungai Musi digolongkan pada tingkat pencemaran ringan.
- The Musi River is the largest and longest river in South Sumatra. The development of population activities in the Musi River Basin can affect river water quality and can cause pollution. The high level of industrial activity and households along the Musi River causes a decrease in environmental quality in the Musi River Basin. The declining quality of aquatic environment can be seen from the presence of phytoplankton. Based on this, further research is needed to determine the extent of pollution in the Musi River Basin. The purpose of this study is to assess saprobitas along the Musi River Basin based on SI (Saprobic Index) value and knowing the level of water pollution using saprobitas water assessment. This study uses plankton as a bioindicator of aquatic organic pollution. This study uses an exploratory design with survey methods, and the determination of sampling stations by purposive sampling method. The results showed abundance of phytoplankton in the waters of the Musi River in the range of 123 to 2581 cells.liter-1 or an average of 1397 cells.liter-1. The Saprobic index in the waters of the Musi River ranges from 0.631 to 1, classified in the phases of the microbial, namely β-Mesosaprobic, so that the waters of the Musi River are classified as mild.
