Abstract

Sungai merupakan perairan yang mengalir dari tempat tinggi ke tempat rendah, aliran air yang membentang melewati daratan dan terdiri dari tiga bagian yaitu hulu, tengah dan hilir. Sungai sangat bermanfaat bagi kehidupan organisme air di sungai. Kegiatan manusia yang menjadi sumber pencemaran bahan organik diantaranya pembuangan limbah ke sungai. Pencemaran bahan organik yang terjadi di sungai mampu mempengaruhi suhu, pH, DO (Dissolved Oxygen), COD (Chemical Oxygen Demand) dan BOD (Biological Oxygen Demand). Berangkat dari permasalahan yang telah diuraikan di atas, saya mengangkat penelitian mengenai Pencemaran Bahan Organik di Sungai Bektiharjo, Kabupaten Tuban. Tujuan penelitian ini yaitu tingkat pencemaran bahan organik di Sungai Bektiharjo dengan menggunakan Metode Indeks Pencemaran (IP) dan Metode Biological Monitoring Working Party – Average Score Per Taxon (BMWP – ASPT). Penelitian ini dilakukan pada Bulan Maret hingga April 2023 di UPT Laboratorium Dinas Lingkungan Hidup Kota Tuban. Penelitian ini terbagi menjadi dua yaitu menggunkana Metode Indeks Pencemaran (IP) untuk mengetahui status mutu air berdasarkan parameter fisika dan kimia serta menggunakan Metode Biological Monitoring Working Party-Average Score Per Taxon (BMWP-ASPT) untuk mengetahui kualitas air sungai berdasarkan makrozoobenthos. Berdasarkan pengukuran Total Organic Matter (TOM) di Sungai Bektiharjo didapatkan hasil tertinggi terdapat pada Stasiun 5 sebesar 15.4 mg/l dan hasil terendah terdapat pada Stasiun 1 sebesar 2.381 mg/l. Hasil pengukuran kualitas air berdasarkan Indeks Pencemaran (IP) mendapati yang masih memenuhi baku mutu terdapat pada Stasiun 1 – 3 yang nilainya <1. Stasiun 4 dan 5 masuk dalam kategori tercemar ringan karena berada pada rentang 1-5. Hasil pengukuran kualitas air dengan menggunakan BMWP-ASPT didapatkan pada Stasiun 1 dan 3 termasuk kategori sangat baik, Stasiun 2 dan 5 masuk dalam kategori sangat buruk, sementara Stasiun 4 masuk ke dalam kategori buruk

English Abstract

Rivers are bodies of water that flow from high areas to low areas, their watercourses stretching across the land and consisting of three parts: the headwaters, middle course, and lower course. Rivers are highly beneficial for the aquatic organisms that inhabit them. Human activities contribute to the pollution of organic materials, including the disposal of waste into rivers. Pollution of organic materials occurring in rivers can affect parameters such as temperature, pH, DO (Dissolved Oxygen), COD (Chemical Oxygen Demand), and BOD (Biological Oxygen Demand). Based on the issues described above, I am conducting a research project on Organic Material Pollution in the Bektiharjo River, Tuban Regency. The objective of this research is to assess the level of organic material pollution in the Bektiharjo River using the Pollution Index (IP) Method and the Biological Monitoring Working Party – Average Score Per Taxon (BMWP-ASPT) Method. This study was conducted from March to April 2023 at the Environmental Laboratory of the Tuban City Environmental Department. The research is divided into two parts: one using the Pollution Index (IP) Method to determine water quality based on physical and chemical parameters, and the other using the Biological Monitoring Working Party-Average Score Per Taxon (BMWP-ASPT) Method to assess the river water quality based on macrozoobenthos. Based on the measurement of Total Organic Matter (TOM) in the Bektiharjo River, the highest result was found at Station 5, amounting to 15.4 mg/l, while the lowest result was at Station 1, which was 2.381 mg/l. The water quality measurement results based on the Pollution Index (IP) indicated that stations 1 to 3 met the quality standards with values <1, while stations 4 and 5 fell into the lightly polluted category with values ranging from 1 to 5. The water quality assessment using the BMWP-ASPT method revealed that stations 1 and 3 belong to the "very good" category, stations 2 and 5 are categorized as "very poor," and station 4 is categorized as "poor."
