ABSTRAK

Sungai Martapura merupakan sumber air yang dimanfaatkan masyarakat untuk berbagai aktivitas, namun keberadaan permukiman dan industri sasirangan berpotensi menurunkan kualitas perairan. Penelitian ini bertujuan untuk menganalisis kualitas air Sungai Martapura di Desa SungaiJingah berdasarkan parameter fisikadan kimia sertamenentukan status kualitas airmenggunakanmetode Indeks Pencemaran(IP),IndeksKualitasAir (IKA),dan Heavy Metal Pollution Index (HMPI). Pengambilan sampel dilakukan pada tiga stasiun pengamatan menggunakan metode purposive sampling. Parameter yang dianalisis meliputi suhu, pH, TSS, DO, BOD, COD, amoniak, Fe, dan Cr. Hasil penelitian menunjukkan bahwa sebagian besar parameter masih memenuhi baku mutu air kelas II, meskipun beberapa parameter seperti DO, amoniak, dan Fe tidak memenuhi baku mutu pada beberapa stasiun. Hasil penelitian menunjukkan bahwa aktivitas antropogenik di sekitar Sungai Martapura berpotensi memengaruhi kualitas perairan sehingga diperlukan upaya pengelolaan dan pemantauan secara berkelanjutan.

ABSTRACT

The Martapura River is a water source used by the community for various activities; however, the presence of settlements and the sasirangan industry has the potential to degrade water quality. This study aims to analyze the water quality of the Martapura River in Sungai Jingah Village based on physical and chemical parameters and to determine the water quality status using the Pollution Index, Water Quality Index, and Heavy Metal Pollution Index methods. Sampling was conducted at three monitoring stations using purposive sampling. Theparameters analyzed included temperature, pH, TSS, DO, BOD, COD, ammonia, Fe, and Cr. The results showed that most parameters still met Class II water quality standards, although some parameters such as DO, ammonia, and Fe, did not meet the standards at certain stations. The results indicate that anthropogenic activities around the Martapura River have the potential to affect water quality, necessitating continuous management and monitoring efforts.
