Daffa Kenian Irsya. 26040117130057. Kandungan Mikroplastik pada Air,
Sedimen, dan Ikan di Kawasan Wisata Mangrove Park Kota Pekalongan
(Bambang Yulianto dan Nirwani Soenardjo)
Kawasan Wisata Mangrove Park Kota Pekalongan merupakan kawasan
konservasi mangrove lokasinya dekat dengan pemukiman dan tempat wisata, hal
ini menyebabkan potensi pencemaran mikropalstik di kawasan ini sangat tinggi.
Mikroplastik merupakan partikel plastik yang berukuran <5mm. Ukurannya yang
kecil menyebabkannya dapat tertransportasikan ke seluruh tempat. Hal ini
dikhawatirkan memberikan dampak yang buruk bagi lingkungan, biota laut, dan
manusia.
Tujuan dari penelitian ini adalah untuk mengetahui keberadaan mikroplastik
yang pada air, sedimen dan ikan di Kawasan Wisata Mangrove Park Kota
Pekalongan, serta untuk mengetahui jumlah, bentuk, warna, ukuran, dan jenis
mikroplastik yang terdapar di kawasan tersebut. Penelitian ini dilakukan pada
bulan Agustus 2021 – Desember 2021.
Sampel air, sedimen dan ikan diekstraksi mikroplastiknya di Laboratoriun
Biologi FPIK Undip. Pengamatan mikroplastik yang teridentifikasi diamati secara
langsung dengan menggunakan mikroskop binokuler. Pengamatan yang dilakukan
meliputi keberadaan, jumlah, bentuk, warna, dan ukuran mikroplastik. Selanjutnya,
satu sampel mikroplastik per lokasi dikirim ke LPPT UGM untuk dilakukan analisis
FTIR (Fourier Transform Infrared). Pengolahan data dilakukan dengan
menggunakan Microsoft Excel secara deskriptif.
Hasil penelitian menunjukkan keberadaan mikroplastik paling banyak
Terdapat pada sedimen di Kawasan Wisata Mangrove Park Kota Pekalongan.
Jumlah mikroplastik yang ditemukan pada sampel air berjumlah 183,3 partikel/L,
pada sampel sedimen 366,67 partikel/kg, sedangkan pada sampel ikan 48
partikel/individu. Bentuk yang ditemukan yaitu fiber, fragmen, pelet, dan film,
dengan warna yang beragam yaitu hitam, merah, biru, transparan, dan kuning.
Rentang ukuran mikroplastik yang ditemukan antara 0,357 – 4,933 mm. Sedangkan
hasil FTIR menunjukkan jenis plastik yang ditemukan LDPE, PP, dan PET.
Kata Kunci: Pencemaran, Ekstraksi, Mikroplastik, FTIR.

SUMMARY

Daffa Kenian Irsya. 26040117130057. Microplastic Content in Water, Sediment,
and Fish at Mangrove Park Tourism, Pekalongan City (Bambang Yulianto and
Nirwani Soenardjo)
The Pekalongan City Mangrove Park Tourism Area is a mangrove
conservation area that is located close to settlements and tourist attractions. This
causes the potential for microplastic pollution in this area to be very high.
Microplastics are plastic particles measuring <5mm. Its small size allows it to be
transported all over the place. This is feared to impact the environment, marine
life, and humans negatively
The purpose of this study was to determine the presence of microplastics
in water, sediment, and fish in the Pekalongan City Mangrove Park Tourism Area
and determine the number, shape, color, size, and type of microplastics found in
the area. This research was conducted from August 2021 – to December 2021.
The samples in this study were water, sediment, and fish taken directly
from the Mangrove Park Tourism Area, Pekalongan City. Microplastic extraction
was carried out at the Biology Laboratory FPIK Undip. Microplastics identified
were observed using a binocular microscope. Observations were made, including
the presence, number, shape, color, and size of microplastics. Furthermore,
microplastic sample discovered from all locations was analyzed for FTIR
(Fourier Transform Infrared) to LPPT UGM. Data processing was done by using
Microsoft Excel descriptively.
The results showed that most microplastics were found in sediments of
the Mangrove Park Tourism Area of Pekalongan City. The number of microplastics
found in water samples was 183.3 particles/L, in sediment samples 366.67
particles/kg, while in fish samples 48 particles/individual. The microplastic
shapes found were fibers, fragments, pellets, and films, with various colors. They
are black, red, blue, transparent, and yellow. The size range of microplastics found
was between 0.357 – 4.933 mm. Meanwhile, the FTIR results show the types of
plastic found in LDPE, PP, and PET.
Keywords: Pollution, Extraction, Microplastic, FTIR.
