Telah dilakukan penelitian tentang kandungan logam berat timbal dalam sedimen dan teritip (Patelloida striata) pada perairan Pelabuhan Jetty Meulaboh, Aceh Barat. Tujuan penelitian ini adalah untuk mengetahui kandungan logam berat timbal pada sedimen dan teritip (Patelloida striata) di perairan Pelabuhan Jetty Meulaboh, Aceh Barat. Penelitian ini dilakukan pada bulan Maret 2024. Pengambilan sampel dilakukan menggunakan metode Purposive Sampling menggunakan pipa paralon dengan panjang 10 cm untuk pengambilan sampel sedimen dan pahat untuk pengambilan sampel teritip. Sampel sedimen dan teritip diambil dari 3 stasiun. Kadar logam timbal pada sampel sedimen dan teritip dianalisis menggunakan Atomic Absorption Spectrophotometer (AAS) di Laboratorium Lingkungan Prodi Teknik Kimia Fakultas Teknik Universitas Syiah Kuala. Hasil analisis kandungan logam berat timbal pada sedimen tertinggi sebesar 1,200 mg/kg dan terendah sebesar 0,579 mg/kg menunjukkan bahwa Pelabuhan Jetty Meulaboh, Aceh Barat belum tercemar logam berat timbal menurut US-EPA (United States Environmental Protection Agency) tahun 2004. Sedangkan, kandungan logam berat timbal pada teritip tertinggi sebesar 0,096 mg/kg dan terendah tidak terdeteksi oleh alat AAS 0,001 mg/kg menunjukkan bahwa biota di perairan Pelabuhan Jetty Meulaboh, Aceh Barat sudah tercemar logam berat timbal menurut Peraturan Pemerintah Indonesia No. 22 tahun 2021.

Research has been conducted on the heavy metal content of lead in sediments and barnacles (Patelloida striata) in the waters of the jetty port, meulaboh West Aceh. The purpose of this study was to determine the heavy metal content of lead in sediments and barnacles (Patelloida striata) in the waters of the Meulaboh West Aceh jetty port. The study was conducted in March 2024. Sampling was carried out using the Purposive Sampling method using a paralon pipe with a length of 10 cm for sediment sampling and chiseling for barnacle sampling. Sediment and barnacle samples were taken from 3 stations. Lead metal levels in sediment and barnacle samples were analyzed using an Atomic Absorption Spectrophotometer (AAS) at the Environmental Laboratory of the Chemical Engineering Study Program, Faculty of Engineering, Syiah Kuala University. The results of the analysis of lead heavy metal content in sediments as high as 1.200 mg/kg and as low as 0.579 mg/kg showed that the Meulaboh Jetty Port, West Aceh had not been contaminated with lead heavy metals according to US-EPA (United States Environmental Protection Agency) in 2004. Meanwhile, the lead heavy metal content in barnacles is the highest of 0.096 mg/kg and the lowest undetected by the AAS tool of 0.001 mg/kg indicates that biota in the waters of Meulaboh Jetty Port, West Aceh has been contaminated with lead heavy metal according to Indonesian Government Regulation No. 22 of 2021.
