Akumulasi Timbal (Pb) dan Kadmium (Cd) Serta Kerusakan Pada Hati, Insang, dan Daging Ikan Patin Pangasius sp) di Waduk Saguling – Sustaninable Potential And Utilizatiom Rates Of Threadfin Bream (Nemipterusjaponicus) In Bay Of Banten Water

Penelitian ini bertujuan untuk mengetahui kadar Timbal (Pb) dan Kadmium (Cd) dalam insang, hati dan daging ikan patin serta mengetahui tingkat kerusakan struktur secara histopatologi. Ikan yang dijadikan obyek penelitian adalah ikan patin (Pangasius sp.) dari Waduk Saguling dan hasil budidaya di Cijengkol Subang.Kadar logam berat Pb dan Cd diuji menggunakan Atomic Absorption Spectometry (AAS). Kadar logam berat yang terakumulasi dalam organ khususnya daging telah melebihi ambang baku mutu SNI 7387:2009. Hasil pengamatan histopatologi yang dilakukan terhadap insang, hati dan daging ikan patin secara umum telah mengalami kerusakan pada organ tersebut. Kerusakan insang diantaranya Melano Makrofag Center (MMC), edema, hiperplasia, kongesti, dan fusi lamela. Kerusakan hati berupa MMC, nekrosis, degenerasi dan degenerasi lemak. Pada daging tidak terjadi perubahan (normal).Kerusakan yang terjadi pada organ diakibatkan oleh adanya timbal dan kadmium yang terakumulasi. Pada sampel organ didapatkan kandungan Pb yaitu, pada insang (0,01-120 ppm), hati (0,01-160 ppm), daging (0,01-130 ppm) dan air tidak terdeteksi.

The purposes of this research was to identified heavy metal concentration of Lead (Pb) and Cadmium (Cd) in the gills, liver and meat catfish and determine the level of damage to organ structure gill, liver and meat histopathology. Fish that made used for this research is catfish (Pangasius sp.) of wild-caught at Saguling reservoir and farmed in Cijengkol Subang. Levels of heavy metals Pb and Cd in the organs tested using Atomic Absorption Spectrometry (AAS). Levels of heavy metal that accumulates in the organ meats in particular has exceeded the quality standard SNI 7387:2009. Histopathological observations were carried out on gill, liver and catfish meat in general has damage to the organ. Damage the gills of which Melano Macrophages Center (MMC), edema, hyperplasia, congestion, and fusion lamella. Liver damage in the form of MMC, necrosis, degeneration and fatty degeneration. In the flesh no change (normally).Damage to the gills, liver and meat of catfish (Pangasiussp.) caused by the presence of lead and cadmium were accumulated. Organ samples obtained at the Pb content, the gills (0.01 to 120 ppm), liver (0.01 to 160 ppm), meat (0.01 to 130 ppm).
