Abstract

Increased human activity along the Tukad Badung River affects the quality of the river's water. One of the causes is waste from various anthropogenic activities containing heavy metals, which can affect the quality of water and the organisms living in it. The purpose of this study was to determine the chromium (Cr) content in water and tilapia (Oreochromis niloticus). The study was conducted in the Tukad Badung River from February to March 2023. The sampling technique used the time-composite and sample-composite methods. The results of the study showed that the Tukad Badung waters were not polluted, as the Cr content did not exceed the thresholds set by Government Regulation of the Republic of Indonesia No. 82 of 2001 and Bali Governor Regulation No. 8 of 2007. Meanwhile, the Cr content in the muscles of tilapia at station II was 0.036 mg/L, and at station III, it was 0.727 mg/L in the muscles and 2,220 mg/L in the gills. The highest Bioconcentration Factor (BCF), which was found in the gills of tilapia, was 74, but the level of Cr accumulation ability at all stations in the Tukad Badung waters was still classified as a low accumulative category.

Abstract

Hadirnya fenol yang melebihi batas ambang ke dalam ekosistem perairan dapat menjadi stresor kimia bagi organisme akuatik, termasuk juga bagi ekosistem muara oleh karena muara (estuaria) merupakan daerah pertemuan antara air tawar dari perairan sungai dan air laut sehingga berpotensi mengandung bahan kimia antropogenik. Kepiting bakau (Scylla spp.) memiliki siklus hidup yang sebagian besar berada pada ekosistem mangrove dan umum digunakan dalam studi ekotoksisitas. Total Haemocyte Count (THC) dan histologi organ insang dapat menginformasikan perubahan histologi akibat stressor oleh karena paparan toksik, terutama fenol. Perlakuan sublethal fenol dengan konsentrasi yang berbeda  terhadap kepiting bakau (Scylla serata) pada hari ke-1, hari ke-3, hari ke-5 dan hari ke-8 tidak terdapat perbedaan yang signifikan (p> 0,05) (Lampiran) terhadap rata-rata Total Haemocyte Count (THC). Namun pada hari ke-7 menunjukkan penurunan jumlah THC pada tiap perlakuan bila dibandingkan dengan kontrol (tanpa perlakuan). Perubahan histologi yang terjadi meningkat sebanding dengan konsentrasi fenol yang diperlakukan terhadap kepiting bakau (S. serata). Perubahan histologi yang terjadi adalah kerusakan struktur dari lamela insang (l) dan bagian terluar sinus lamela atau outer lamellar sinuses (ols) yang meliputi infiltrasi hemosit, hiperplasia maupun nekrosis.Kata Kunci : fenol, hepatopankreas, kepiting bakau.
