Fadhilah, Arriel and Dr. Eng. Ir. Riyanto Haribowo,, ST., MT., IPM. and Dr. Eng. Martiwi Diah Setiawati (2023) , Kajian Distribusi dan Kelimpahan Mikroplastik Sungai Bango pada Tata Guna Lahan yang Berbed. Sarjana thesis, Universitas Brawijaya.
Abstract
Plastik merupakan material yang praktis dan ekonomis sehingga penggunaannya dalam berbagai kegiatan manusia tidak dapat dihindarkan. Sebagian besar plastik yang telah digunakan tidak terkelola dengan baik sehingga berpotensi mencemari dan mengancam ekosistem perairan. Partikel plastik yang terakumulasi di perairan akan terdegradasi menjadi mikroplastik (plastik dengan ukuran sebesar 1 μm hingga 5 mm). Pencemaran mikroplastik di laut telah menjadi ancaman bagi ekosistem perairan dan kesehatan manusia. Sungai diduga menjadi salah satu kontributor terbesar pencemaran mikroplastik di laut. Studi ini dilakukan untuk mengetahui distribusi dan karakteristik pencemaran mikroplastik di Sungai Bango pada tata guna lahan yang berbeda. Peninjauan dilakukan pada 5 titik pengambilan sampel yang tersebar sepanjang Sungai Bango. Ekstraksi mikroplastik dilakukan dalam laboratorium melalui metode filtrasi, separasi densitas, dan wet peroxidation (WPO). Mikroplastik yang didapatkan kemudian dianalisis berdasarkan ukuran, warna, bentuk, dan jenis polimer untuk mengetahui karakteristiknya. Nilai kelimpahan mikroplastik rerata yang didapatkan di Sungai Bango adalah 85.40 partikel/L, dengan konsentrasi tertinggi terjadi pada bagian Hilir 2 (BN-5) dengan nilai kelimpahan 137.00 partikel/L, sedangkan nilai kelimpahan terendah terjadi di bagian Tengah 1 (BN-2) dengan nilai 44.33 partikel/L. Bentuk film, warna transparan, dan klasifikasi ukuran Small Microplastic Particle (SMP) mendominasi lokasi studi. Adapun jenis polimer yang ditemukan adalah Poly(vinylchloride) (PVC), Polypropylene (PP), Polystyrene (PS), dan High Density Polyethylene (HDPE). Kondisi pencemaran mikroplastik di Sungai Bango mayoritas disebabkan oleh degradasi partikel plastik (mikroplastik sekunder) akibat aktivitas manusia. Hal tersebut ditunjukkan melalui dominasi litter-related plastic di sepanjang Sungai Bango yang ditemukan. Selain itu, dalam studi ini ditemukan bahwa keberadaan aktivitas industri berpotensi menjadi point source pollution.
English Abstract
Plastic is a practical and economical material so its use in various human activities cannot be avoided. Mismanaged plastic has the potential to pollute and threaten the aquatic environment. Plastic particles that accumulate in water will be degraded into microplastics (e.g., plastics with a size of 1 μm to 5 mm). Microplastic pollution in the aquatic environment has also become a threat to human health. Rivers are suspected to be one of the biggest contributors to microplastic pollution in the sea. In this study, we assess the distribution and characteristics of microplastic pollution in the Bango River at various land uses. The study was conducted at 5 sampling points along the Bango River. Microplastic extraction was conducted in the laboratory through filtration, density separation, and wet peroxidation (WPO) methods. The obtained microplastics were then observed based on size, color, shape, and polymer type to determine their characteristics. The average microplastic abundance value in the Bango River was 85.40 particles/L, with the highest concentration in the downstream (BN-5) section with an abundance value of 137.00 particles/L, while the lowest abundance value occurred in the middle (BN-2) section with a value of 44.33 particles/L. Film shape, transparent color, and Small Microplastic Particle (SMP) size dominate the study locations. The types of polymers found were Poly(vinyl chloride) (PVC), Polypropylene (PP), Polystyrene (PS), and High- Density Polyethylene (HDPE). We found out that the majority of microplastic pollution in the study site is caused by the degradation of plastic particles (secondary microplastics) from human activities. This is shown by the dominance of litter-related plastic found along the Bango River. In addition, this study found that industrial activities have the potential to become microplastic point- source pollution.
