Abstract

Mikroplastik merupakan potongan plastik berukuran <5mm. Berdasarkan sumbernya, mikroplastik dibedakan menjadi mikroplastik primer yang berasal dari proses produksi plastik berukuran kecil untuk kepentingan tertentu dan mikroplastik sekunder berasal dari proses penguraian plastik yang lebih besar. Penelitian ini dilakukan di Hilir DAS Brantas kota Gresik yang sebelumnya terindikasi tercemar oleh mikroplastik. Tujuan dari penelitian ini yaitu mengetahui jenis, kelimpahan dan sumber mikroplastik di Hilir DAS Brantas. Pengambilan sampel dilakukan pada 3 stasiun, yaitu Perning, Wringinanom, dan Pasinan. Identifikasi menggunakan mikroskop trinokuler. Identifikasi air dan sedimen menggunakan metode NOAA. Hasil penelitian menunjukkan bahwa kelimpahan mikroplastik tertinggi yakni berada di Desa Pasinan (Air) dan Desa Perning (Sedimen). jenis mikroplastik didominasi oleh jenis filamen. Hal ini dipengaruhi oleh banyaknya kemasan sachet dan tas kresek di bantaran sungai. Kemudian untuk warna didominasi oleh warna biru dan hitam. Mikroplastik yang ditemukan rata-rata berukuran 101-500 µm.

Abstract

The commonly used human blood group system is the ABO system. Determination of blood group is important in blood transfusion activities. The purpose of this study was to determine the frequency of the ABO blood group system and the frequency of the ABO blood group allele in students of the Biology and Science Education study program at UIN Sunan Ampel Surabaya. Determination of blood group was carried out by the Slide Test method which was carried out randomly with a sample of 90 people. Determination of blood group is done by the principle of agglutination that occurs between antigens and antibodies. The results showed the frequency of blood group ABO system: A (20%); B (24%); AB (10%); O (46%). IA allele frequency (0.13); IB (0.07); IO (0.8). The proportion of the highest frequency of blood type is blood type O. These results indicate that the distribution of blood type O among students at UIN Sunan Ampel Surabaya is relatively the same as the results of other studies conducted in Indonesia.
