Abstract

Estuari Sungai Musi merupakan perairan semi tertutup yang dipengaruhi oleh dinamika pasang surut sehingga hanya beberapa biota khas yang mampu bertahan hidup di kawasan ini. Penelitian ini bertujuan untuk memahami tingkat biodiversitas kelompok gastropoda dan krustasea yang hidup pada zona intertidal estuari Sungai Musi. Pengambilan sampel dilakukan pada Bulan November 2021 di 5 titik stasiun pengamatan dengan metode transek kuadrat. Pengukuran kualitas perairan dilakukan meliputi suhu, pH, oksigen terlarut, dan salinitas. Hasil penelitian menunjukkan bahwa komposisi individu total krustasea (52%) dan gastropoda (48%). Kelimpahan total tertinggi hingga terendah secara berurutan ditemukan pada stasiun 4, 5, 2, 1, dan 3. Nilai indeks keanekaragaman berkategori sedang dengan nilai 1.30 – 1.76 nilai indeks keseragaman berkisar 0.48 – 0.65, nilai indeks dominansi 0.19 – 0.30. Berdasarkan hasil PCA menunjukkan bahwa F1 terdiri dari stasiun S1, S2, S4, dan S5 dengan variabel utama suhu, salinitas, DO, pH, keanekaragaman, keseragaman, dan dominansi sedangkan F2 terdiri dari stasiun S3 dengan kelimpahan. Berdasarkan hasil penelitian ini, zona intertidal menjadi habitat yang baik untuk kedua kelompok namun lokasi habitatnya cukup berpengaruh terhadap sebarannya secara spasial.

Abstract

Heavy metal pollution from anthropogenic activities can harm aquatic ecosystems. This study aims to determine the concentration of heavy metals (Pb and Cu) in waters, sediments, and mud crabs (Scylla serrata), and to analyze the relationship between environmental parameters and S. serrata consumed by humans. Samples were taken in the mangrove ecosystem around the Tanjung Api-Api port area in South Sumatra, Indonesia. Pb and Cu analysis used the Atomic Absorption Spectrophotometer (AAS). Pb and Cu linkages in waters, sediments, and S. serrata analyzed by SigmaPlot V12.5 and Principal Component Analysis (PCA) analyzed by XLSTAT 2022. The limit consumption of S. serrata was calculated using MWI (Maximum Weekly Intake) and MIT (Maximum Intake Tolerance). Based on the results, the heavy metal Pb in water was 0.1055 – 0.1322 mg.L-1, and Cu was not detected. Furthermore, Pb in sediments ranged from 7.0104 - 11.8186 mg.kg-1, Cu 3.7127 - 4.5347 mg.kg-1, and Pb in S. serrata ranged from 0.0001 - 0.0021 mg.kg-1, and Cu ranged from 0.03 – 0.0791 mg.kg-1. The concentration of heavy metals in water, sediment, and S. serrata had not exceeded the specified quality standard, except for Pb in water. The principal component analysis obtained F1 (44.35%), F2 (27.53%) and F3 (17.83%) groups. Based on MWI and MIT value, it showed high quality which concluded S. serrata was still safe for human consumption.

Abstract

Seagrass species thrive in coastal ecosystems and known for their ability to accumulate heavy metals from their surrounding environment. This study aims to evaluate the ecological risks related to the accumulation of heavy metals in seagrass roots, leaves, and sediments. The seagrass examined belong to the genera Cymodocea and Thalassia, collected from two sites: Jeralangan and Cukuh Nyai on Pahawang Island, Lampung, Indonesia. The heavy metals analyzed included Pb, Cu, Ni, and Zn, which were measured using the wet destruction method and quantified with a SHIMADZU AA-7000 Atomic Absorption Spectrophotometer (AAS). The ecological risk was evaluated through various indices, such as the Bioconcentration Factor (BCF), Translocation Factor (TF), Geoaccumulation Index (Igeo), Contamination Factor (Cf), and Pollution Load Index (PLI). The highest concentrations of heavy metals in sediment were detected at station 1 was Zn (15.486 mg.kg-1). In the roots of Cymodocea was Zn (8.772 mg.kg-1), while the highest concentration in leaves was Cu in Thalassia (10.541 mg.kg-1). The ecological risk assessment revealed that BCF < 1 categorize an excluder, while TF > 1 for Pb and Zn indicate effective translocation from roots to leaves. Additionally, Igeo < 0 signify no contamination, Cf < 1 indicate low pollution levels, and PLI < 0 confirm a non-polluted status. In conclusion, the results show that the seagrass ecosystems at the study sites currently have low levels of heavy metal pollution and minimal ecological risk, suggesting they remain in a relatively safe condition.

Abstract

Littoral zone often face environmental pressure due to anthropogenic activities, which can impact the quality of their ecosystem. This study analyzes the concentrations of copper (Cu) and lead (Pb) in sediments and benthic (Anadara granosa and Cerithidea cingulata). Sampling procedures were implemented during September 2022 across the aquatic habitats of Sembilang National Park, in South Sumatra Province, using the purposive sampling method. Sediment grain size and substrate type were analyzed using Shepard’s triangle. Metal detection using a spectrophotometric method based on atomic absorption. The results showed that the sediment fraction mostly consisted of clay, ranging from 92.03% to 94%. Cu concentrations in the sediment ranged from 5.01±0.017 to 5.71±0 mg/kg, while Pb concentrations ranged from 10.5±0.195 to 11.51±0.395 mg/kg. In the benthic, Cu concentrations ranged from 0.0037±0.00005773 to 0.0147±0.00000346 mg/kg, and Pb concentrations ranged from 0.0001±0.000227 to 0.005±0 mg/kg. According to the statistical evaluation testing via independent sample t-test showed that heavy metals differed significantly (p <0.05) between sediment and benthic compartments. These results show that the environmental quality in Sembilang National Park is still comparatively well maintained and within current quality requirements, despite certain activities that have the potential to pollute the environment. To guarantee the long-term viability of this area, it is advised that environmental quality be frequently monitored as a mitigation action.

Abstract

Aktivitas antropogenik yang meningkat telah memicu masuknya polutan ke perairan, salah satunya mikroplastik (MPs) yang terbentuk dari degradasi limbah plastik. Penelitian ini bertujuan untuk menganalisis kepadatan MPs pada biota kerang Anadara granosa yang banyak ditemukan di habitat mudflat Barong yang berada di kawasan pesisir Taman Nasional Sembilang, namun secara geografis dekat dengan muara sungai-sungai besar. Sampel diambil berdasarkan ukuran berbeda: BL= Barong Large (20-25 gr), BM= Barong Medium (15-20 gr), dan BS= Barong Small (10-15 gr). Ekstraksi MPs dilakukan menggunakan metode ekstraksi basa dengan larutan KOH 10%, diikuti penyaringan dan identifikasi secara visual menggunakan mikroskop. Kepadatan MPs dihitung berdasarkan jumlah partikel per gram berat tubuh basah biota. Hasil menunjukkan bahwa nilai kepadatan tertinggi terdapat pada BL (20 partikel/gr), diikuti BS (16 partikel/gr), dan terendah pada BM (13 partikel/gr). Jenis MPs yang dominan adalah fiber dan fragmen, dengan warna dominan hitam dan putih. Temuan ini menunjukkan bahwa habitat mudflat Barong yang berada di kawasan terlindung, ternyata telah terdampak limbah antropogenik MPs yang diduga bersumber dari muara sungai-sungai besar terdekat. Selain itu, temuan ini menjadi potensi akumulasi MPs, yang dapat membahayakan biota bentik dan rantai makanannya melalui proses bioakumulasi dan biomagnifikasi.
