Pengaruh merkuri nitrat [Hg (NO3)2] dengan konsentrasi berbeda terhadap benih ikan kakap putih (Lates calcarifer Bloch): histologi insang

Abstract

AbstrakBanyaknya industri yang berkembang dewasa menyebabkan meningkatnya kadar logam berat seperti merkuri dalam perairan. Penelitian ini bertujuan untuk mengetahui pengaruh [Hg (NO3)2] dengan konsentrasi yang berbeda terhadap benih ikan kakap putih (L. calcarifer): histologi insang. Dalam penelitian ini, ikan dipaparkan dengan konsentrasi 3,16 x 10 -2 ppm, 9,99 x 10 -2 ppm, 3,16 x 10 -1 ppm dan 9,97 x 10 -1 ppm. Total ikan yang digunakan untuk histologi adalah 15 ekor. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi [Hg (NO3)2] maka kerusakan pada jaringan insang ikan juga akan meningkat dan mempercepat waktu kematian ikan. Kerusakan yang terjadi yaitu hipertropi dan hiperplasia pada sel epitel insang, fuse pada lamela sekunder dan haemorhage di insang pada konsentrasi [Hg (NO3)2] yang lebih tinggi. Kata kunci: Merkuri; Kakap putih; Insang; Histologi AbstractMany industries today lead to increased levels of heavy metals such as mercury in water. This research aims to determine the effect of different concentrations of [Hg (NO3) 2] to Asean Sea Bass (L. calcarifer): Gill Histology. In this study, this fishes was treated with 3,16 x 10 -2 ppm, 9,99 x 10 -2 ppm, 3,16 x 10 -1 ppm, and 9,97 x 10 -1 ppm. Total fishes used for histological study was 15 fishes. Results of this research showed that increasing the consentrations of the [Hg(NO3)2] will also increase the damage on the stomach structure and fasten the mortality time of the fish. Damage that occurs is hypertrophy and hyperplacia on epitel cells, fuse of secundary lamellae and haemorhage on gill that were exposed to high consentration of [Hg(NO3)2].

Morfometrik Sistem Pencernaan Ikan Nila (Oreochromis niloticus) yang Dipapar Limbah Cair Kelapa Sawit

“…Sel mukosa yang ada di seluruh permukaan lambung akan mensekresi lendir yang berlebih dan akan menutupi seluruh permukaan lambung. Kondisi seperti ini membuat ikan kehilangan nafsu makan karena proses pencernaannya (Ezraneti dan Windarti, 2015).…”

Analysis of Liver Histology Several Fish in the Air Kotok River in the Gold Mining Area, Lebong Regency

“…Fish can acquire heavy metals in two different ways, directly through permeable membranes or indirectly through food and water consumption through the digestive system (Das et al, 2017). Additionally, according to (Ezraneti, 2016), heavy metals like mercury can harm fish organs like the digestive and respiratory systems as well as through skin penetration. According to (Nordan et al, 2020), fish samples from former mining ponds revealed mercury levels of 155.7 ppb, which was beyond the allowable limit for human consumption.…”
