Heavy Metal (Pb and Cu) and Bacterial Contamination in Mudskipper, Eeltail Catfish and Mud Clam at Kuala Tambangan Mangrove Ecosystem, South Kalimantan

Abstract

Heavy metal content (Pb and Cu) in waters and sediments from the Kuala Tambangan mangrove ecosystem, South Kalimantan was above the standard of Minister Environment of the Republic of Indonesia in 2004. Lead content in waters is reached 0.128 mg/L and Cuprum at 0.444 mg/L, but in the sediments is increased dramatically almost 10 times (17,426 mg/gr for Lead and 20,576 mg/gr for Cuprum. The highest content of Lead (0.128 mg/L) was found in the estuary while for Cuprum (0.444 mg/L) found in the interior. The highest value of Lead (17,426 mg/gr) and Cuprum (20,576 mg/gr) for sediments were found in the estuary. Lead content in eeltail catfish and mud clam is can not be detected, but for Mercury (0.1601 mg/kg in eeltail catfish and 0.2653 mg/kg in mud clam) is above the standard of ISO 2354.6-2016. The Total Plate Count values of inhabitants fauna in mangrove ecosystems were below the standard of SNI 2332.3-2015. A qualitative test for Escherichia coli, Salmonella, and Vibrio cholera presents shows a negative value (<3 APM/g). Coliform quantitative test is above the standard of quality (43 APM/gr in eeltail catfish and 150 APM/g in mud clam). The presence of parasites was not found on all samples.

IDENTIFIKASI PARASIT PADA IKAN KEMBUNG (Rastrelliger sp.) DI TEMPAT PELELANGAN IKAN SIBOLGA

“…Pemeriksaan ektoparasit dilakukan dengan mengikuti prosedur Sistem Manajemen Mutu sesuai (Kadarsah et al, 2020) tentang penentuan parasit pada produk perikanan, yaitu : panjang total ikan diukur dan berat ditimbang, lendir bagian luar tubuh, lendir operculum diletakan di object glass dan ditetesi NaCl kemudian tutup insang, filamen insang dan sirip dipotong dan dipindahkan pada gelas preparat dan ditetesi NaCl kemudian dilakukan pengamatan terhadap hasil kerokan dan potongan insang serta sirip dibawah mikroskop dengan perbesaran 4-40 kali. Sedangkan pemeriksaan endoparasit dilakukan dengan cara, ikan kembung dibedah dimulai dari anus hingga di bawah sirip dada, organ dalam ikan dikeluarkan kemudian dimasukkan ke dalam petri dish yang telah terdapat larutan NaCl.…”
