Abstract

Latar belakang: Sungai Kali Mas berbatasan langsung dengan pemukiman yang dapat berpotensi menyediakan berbagai sumber mikroplastik yang bersumber dari limbah cucian, produk perawatan pribadi dan sampah domestik.Penelitian ini bertujuan untuk identifikasi karakteristik fisik mikroplastik di Sungai Kalimas.Metode: Penentuan lokasi sampling dengan metode purposve Sampling. Sampel diambil di 3 (tiga) titik lokasi yaitu pada hulu, tengan dan hilir sungai. Sampel diambil pada pagi, siang dan sore hari pada setiap lokasi sampling. Total keseluruhan sampel berjumlah 9 sampel. Pengambilan sampel dilakukan  dengan alat plankton net selama satu jam pada masing-masing lokasi. Identifikasi karakteristik (bentuk, warna dan ukuran) mikroplastik dilakukan dengan menggunakan mikroskop stereo mengacu pada analisis laboratorium NOAA (National Oceanic and Atmospheric Administration).Hasil: Konsentrasi mikroplastik di lokasi hulu, tengah dan hilir masing-masing sebesar 0,049 item/m3, 0.053 item/m3 dan 0.095 item/m3. Bentuk mikroplastik terdiri dari fiber 82%, Fragmen 6% dan filamen 12%. Rata-rata ukuran mikroplastik SMP 65% dan LMP 35% dan rata-rata warna mikroplastik transparan 34%, biru 29%, hitam 20%, kuning 2% dan merah 14%.Simpulan:Karakteristik mikroplastik didominasi oleh bentuk fiber 82%, warna transparan 34% dan ukuran SMP 65%. Sehingga, diperlukan IPAL komunal di daerah sekitar sungai Kalimas untuk menghindari sumber mikroplastik berbentuk fiber yang berasal dari kegiatan penduduk. ABSTRACT Title : Identification of Physical Characteristics of Microplastics in Kalimas River, Surabaya, East JavaBackground:kalimas river is directly located next to a residential area that can potentially provide various microplastic sources from laundry activities,  personal care products, and domestic waste. Thus,this study aimed to identify the physical characteristics of microplastics in the Kalimas River.Method: Determination of the sampling location by purposive sampling method. Samples were taken at 3 (three) location points, namely upstream, middle and downstream of the rive. Sampling was taken in the morning, afternoon and evening at each sampling location. The total number of samples are 9 samples. Sampling was carried out using a plankton net for one hour at each location. Identification characteristics of microplastics (shape, color and size) was carried out using a stereo microscope referring to the NOAA (National Oceanic and Atmospheric Administration) laboratorium laboratory analysis.Result:The concentration of microplastics in the upstream, middle and downstream locations were 0.049 items/m3, 0.053 items/m3 and 0.095 items/m3 respectively. The microplastic shapes comprised fiber 82%, fragment 6% dan filamen 12%. The average of microplastic size were 65% for SMP and 35% for LMP and average of microplastic color were transparan 34%, blue 29%, black 20%, yellow 2% and red 14%.Conclusion: characteristic microplastic in the water were dominated by fiber shaped 82%, transparent coloured 34% and size SMP 65%.  Thus, a communal WWTP is needed in the area around the Kalimas river to avoid sources of fiber microplastic originating from resident activities.

Abstract

Latar belakang: Sungai Beringin berbatasan langsung dengan pemukiman yang dapat berpotensi menyediakan berbagai sumber pencemar yang bersumber dari limbah laundry, limbah industri dan limbah domestik. Penelitian ini bertujuan untuk mengetahui konsentrasi pencemar dan dibandingkan dengan baku mutu limbah laundry dan untuk mengetahui status mutu air dengan metode indeks pencemaran  air Sungai Beringin.Metode: Pengambilan sampel dilakukan pada tiga lokasi sampling di Sungai Beringin yaitu Jembatan Tambakaji, Perumahan griya beringin, dan kelurahan Wonosari. Metode pengambilan sampel mengacu pada SNI 6989.59:2008. Pengambilan sampel air dilakukan dengan menggunakan jerigen dan ember sebanyak 1 liter. Sampel air diambil pada waktu pagi dan siang hari. Adapun parameter – parameter yang diamati adalah MBAS, DO, COD, BOD, dan TSS. Pengujian parameter dilakukan di Laboratorium Teknik Lingkungan UNDIP. Hasil pengujian kualitas air dibandingkan dengan PP No. 22 Tahun 2021 mengenai baku mutu air sungai dan ditentukan status mutu kualitas air dengan metode indeks pencemar.Hasil: Debit minimum Sungai Beringin yaitu sebesar 0,18 m3/detik, dan debit maksimum adalah 2,60 m3/detik. Kandungan MBAS tertinggi terdapat pada lokasi sampling drainase yaitu 30,081mg/L. Kandungan kadar terbesar COD adalah 416,67 mg/L dan BOD adalah 129,17 mg/L. Berdasarkan perbandingan hasil analisis dengan baku mutu yaitu kandungan MBAS, COD, dan BOD melebihi nilai baku mutu yang ditentukan. Nilai baku mutu MBAS adalah 5 mg/L, COD adalah 100 mg/L, dan BOD adalah 6 mg/L.Simpulan: Kualitas sungai beringin berstatus tercemar ringan ditunjukkan dengan nilai indeks pencemaran > 1. ABSTRACT Title : Quality Study of Beringin River Water Polluted by Laundry WasteBackground: The Beringin River is directly adjacent to settlements which can potentially provide various sources of pollution from laundry waste, industrial waste and domestic waste. This study aims to determine the concentration of pollutants and compare it with the quality standard of laundry waste and to determine the status of water quality using the Beringin River water pollution index method.Methods: Sampling was carried out at three sampling locations on the Beringin River, namely Tambakaji Bridge, Griya Beringin Housing, and Wonosari Village. The sampling method refers to SNI 6989.59:2008. Water sampling was carried out using a 1 liter botol and bucket. Water samples were taken in the morning and afternoon. The parameters observed were MBAS, DO, COD, BOD, and TSS. Parameter testing was carried out at the UNDIP Environmental Engineering Laboratory. The results of water quality testing are compared with PP No. 22 of 2021 concerning river water quality standards and determining the status of water quality using the pollutant index method.Result: The minimum discharge of the Beringin River is 0.18 m3/second, and the maximum discharge is 2.60 m3/second. The highest MBAS content was found at the drainage sampling location, which was 30,081mg/L. The highest content of COD is 416.67 mg/L and BOD is 129.17 mg/L. Based on the comparison of the results of the analysis with quality standards, namely the content of MBAS, COD, and BOD exceeding the specified quality standard values. The standard value for MBAS is 5 mg/L, COD is 100 mg/L, and BOD is 6 mg/L.Conclusion: The quality of the Beringin river is lightly polluted as indicated by the pollution index value > 1
