Subekti, Wiwit (2021) Identifikasi Kelimpahan Mikroplastik Pada Air Dan Lambung Ikan Wader Cakul (Puntius binotatus) Di Waduk Selorejo, Kabupaten Malang, Jawa Timur. Sarjana thesis, Universitas Brawijaya.
Abstract
Kehadiran mikroplastik di lingkungan perairan menjadi permasalahan pencemaran air yang terus-menerus selalu ada di setiap tahunnya, karena mikroplastik mengandung bahan kimia yang toksik dan bersifat karsinogenik. Oleh karena itu, organisme yang mengkonsumsinya secara tidak langsung berpotensi mengalami kerusakan pada organ di dalamnya dan dapat menyebabkan kematian pada organisme perairan. Alasan dilakukan penelitian mengenai mikroplastik di Waduk Selorejo ini adalah untuk menganalisis jenis dan kelimpahan mikroplastik yang berada di perairan tersebut. Hal ini di harapkan agar dapat menjadi sumber informasi mengenai pentingnya menjaga kondisi perairan dari sampah plastik serta dapat dijadikan rujukan untuk pemerintah dan masyarakat dalam menentukan kebijakaan pengelolaan berkelanjutan mengenai pencemaran perairan di Waduk Selorejo. Waktu pelaksanaan penelitian ini dilakukan pada November 2020-Maret 2021. Metode yang digunakan yaitu metode deskriptif dengan teknik survei. Penentuan titik sampling dilakukan dengan teknik purposive sampling metode ini dipilih karena dapat menentukan titik stasiun sesuai dengan keperluan peneliti. Pengambilan lokasi untuk sampling dilakukan di 3 titik yaitu titik 1 (inlet), titik 2 (tengah) dan titik 3 (outlet). Prosedur penelitian dilakukan di lapang untuk mengambil sampel air dan ikan, kemudian diberi perlakuan di laboratorium dan dianalisis data. Parameter kualitas air yang diukur saat di lapang yaitu Suhu, TDS, DO dan pH. Analisis data yang dilakukan yaitu dengan menggunakan uji one-way ANNOVA dan uji korelasi pearson. Hasil penelitian didapatkan bahwa terdapat 3 jenis mikroplastik pada sampel air dan ikan wader. Jenis mikroplastik yang ditemukan yaitu diantaranya fragmen, fiber dan film. Persentase kelimpahan mikroplastik pada sampel air yaitu fragmen 62,51%, fiber 19,76% dan film 17,73%. Sedangkan persentase kelimpahan pada sampel ikan didapatkan pada jenis fragmen 56,67%, fiber 24,53% dan film 18,80%. Kelimpahan rata-rata mikroplastik pada sampel air sebesar 537,6 partikel/m³-1897,6 partikel/m³. Kelimpahan rata-rata mikroplastik pada sampel ikan sebesar 2,00-6,03 partikel/individu. Sehingga dapat disimpulkan bahwa kelimpahan mikroplastik pada air memiliki kelimpahan lebih tinggi daripada ikan. Hal ini dapat dilihat dari hasil persentase keselurahan yaitu, pada air didapatkan hasil persentase keseluruhannya sebesar 54,3%. Sedangkan hasil persentase keseluruhan pada ikan yaitu sebesar 45,7%. Hasil signifikan uji korelasi person yang di diperoleh bernilai positif, yang artinya hubungan kelimpahan mikroplastik pada air dan ikan berkorelasi. Hasil data kualitas air pada suhu sebesar (24,4°C-28,3°C), TDS (62mg/l-92mg/l), pH (6,86-8,51), dan DO (9,2ppm-11,2ppm). Saran yang diberikan dalam penelitian ini yaitu, agar dilakukannya monitoring pemantauan dan pengendalian pencemaran di Waduk Selerejo. Hal ini diperlukan agar di perairan tersebut tidak tercemar sampah plastik yang dapat menimbulkan keberadaan mikroplastik, karena ini dapat menimbulkan dampak negatif kepada manusia ataupun biota perairan.
English Abstract
The presence of microplastics in the aquatic environment is a problem of water pollution that continues to exist every year, because microplastics contain toxic and carcinogenic chemicals. Therefore, organisms that consume it indirectly have the potential to experience damage to the organs in them and can cause death to aquatic organisms. The reason for conducting research on microplastics in the Selorejo Reservoir is to analyze the types and abundance of microplastics in these waters. It is hoped that this can be a source of information regarding the importance of maintaining water conditions from plastic waste and can be used as a reference for the government and the community in determining sustainable management policies regarding water pollution in the Selorejo Reservoir. The time of this research was conducted in November 2020-March 2021. The method used was descriptive method with survey techniques. The sampling point was determined by using purposive sampling technique. This method was chosen because it can determine the station point according to the needs of the researcher. The sampling location was carried out at 3 points, namely point 1 (inlet), point 2 (center) and point 3 (outlet). The research procedure was carried out in the field to take water and fish samples, then treated them in the laboratory and analyzed the data. Water quality parameters measured in the field are temperature, TDS, DO and pH. Data analysis was performed using one-way ANNOVA test and Pearson correlation test. The results showed that there were 3 types of microplastics in water samples and wader fish. The types of microplastics found include fragments, fibers and films. The percentage of abundance of microplastics in water samples were 62.51% fragments, 19.76% fiber and 17.73% film. While the percentage of abundance in fish samples was obtained in the type of fragment 56.67%, fiber 24.53% and film 18.80%. The average abundance of microplastics in the water samples was 537.6 particles / m³-1897.6 particles / m³. The average abundance of microplastics in fish samples was 2.00-6.03 particles / individual. So it can be concluded that the abundance of microplastics in water has a higher abundance than fish. This can be seen from the results of the overall percentage, namely, in water the overall percentage results are 54.3%. While the overall percentage results in fish were 45.7%. The significant result of the person correlation test obtained is positive, which means that the relationship between the abundance of microplastics in water and fish is correlated. The results of water quality data at temperatures of (24.4 ° C-28.3 ° C), TDS (62mg / l-92mg / l), pH (6.86-8.51), and DO (9.2ppm- 11.2ppm). Suggestions given in this research are to carry out monitoring, monitoring and control of pollution in Selerejo Reservoir. This is necessary so that the waters are not contaminated with plastic waste which can lead to the presence of microplastics, because this can have a negative impact on humans or aquatic biota.
