Abstract

Water quality in the form of turbidity, colour, odour, taste and suspended residue are significant issues in Sungsang Banyuasin. The filter utilizes a filtration method to remove solid particles and contaminants. The research site consists of Sungsang, Sungsang II, and Sungsang III areas. The purpose of this study was to determine the water quality in the form of colour, taste, odour, turbidity, suspended residue, and salinity, as well as the ability of the filter to overcome water quality. Filtration consists of sedimentation, filter membranes, and filter media consisting of zeolite, silica, anthracite, ferrolite, activated carbon, and bioring. Water quality measurements used organoleptic to determine odour and taste, handrefractometer to measure salinity, direct reading to measure suspended residue, and spectrophotometry to measure colour and turbidity. The breech water was odourless and tasteless, and the suspended residue value ranged from 17-19 mg/L below the quality standard of 50 mg/L. Colour and turbidity values are greater than 50 on their respective scales and salinity values range from 11-13 ppt. The filtration process successfully reduced the values of suspended residue, colour, turbidity, and salinity.

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

Penelitian ini mengkaji keberadaan dan distribusi mikroplastik di muara dan sepanjang Sungai Musi di Sumatera Selatan, Indonesia—suatu kawasan yang terdampak berat oleh pencemaran industri, domestik, dan pertanian. Sampel diambil dari lima stasiun, dengan hasil menunjukkan rata-rata konsentrasi mikroplastik sebesar 33,8 partikel/m3. Konsentrasi tertinggi ditemukan di pertemuan Sungai Upang, kemungkinan akibat limpasan perkotaan dan buangan industri, sementara konsentrasi terendah terdeteksi di sekitar Jembatan Ampera dan Pulau Kemaro, di mana turbulensi air lokal dapat mendorong terjadinya sedimentasi mikroplastik. Mikroplastik yang teridentifikasi didominasi oleh fragmen (77,5%) dan serat (22,5%), dengan sebagian besar partikel berada dalam kisaran ukuran 301–500 µm. Jenis polimer yang paling dominan adalah Low-Density Polyethylene (LDPE), yang umumnya berasal dari limbah kemasan konsumen. Temuan ini menegaskan peran Sungai Musi sebagai jalur transportasi mikroplastik dari daratan menuju ekosistem laut, yang berpotensi menimbulkan risiko besar terhadap keanekaragaman hayati akuatik dan rantai makanan. Selain merusak habitat perairan, mikroplastik juga dapat menjadi media pembawa logam berat dan zat beracun lainnya, sehingga memperparah dampak ekologisnya.

Abstract

Mangrove merupakan ekosistem pesisir yang penting karena mampu melindungi garis pantai, menyerap karbon, menyediakan habitat bagi biota, serta berperan sebagai penyaring polutan. Namun, tekanan aktivitas manusia di wilayah pesisir, seperti keberadaan pelabuhan, aktivitas perikanan, dan masukan limbah domestik dari daratan, dapat berkontribusi terhadap masukan logam berat baik di air maupun terakumulasi dalam sedimen. Penelitian ini bertujuan mengevaluasi status cemaran Pb dan Cu pada sedimen mangrove di Muara Sungai Banyuasin yang berdekatan dengan Pelabuhan Tanjung Api-api. Pengukuran konsentrasi logam berat dilakukan dengan metode Flame Atomic Absorption Spectrophotometry. Rata-rata kandungan Pb (20,71–21,61 mg/kg) dan Cu (10,81–10,99 mg/kg) masih berada di bawah ambang batas baku mutu lingkungan (Pb 50 mg/kg; Cu 65 mg/kg). Nilai Faktor Kontaminasi menunjukkan Pb termasuk kategori sedang, dan Cu tergolong rendah. Nilai Indeks Geoakumulasi ≤ 0 menunjukkan sedimen berada pada kondisi tidak tercemar dan Indeks Beban Pencemaran > 0–2 mengindikasikan berada dalam kondisi tercemar ringan. Secara keseluruhan, kualitas sedimen di Muara Sungai Banyuasin tidak menimbulkan risiko signifikan terhadap biota perairan, serta menunjukkan peran penting mangrove sebagai penahan akumulasi logam berat. Hasil penelitian ini memberikan dasar ilmiah bagi pengelolaan lingkungan pesisir, khususnya sebagai acuan dalam pemantauan kualitas sedimen dan pencegahan potensi pencemaran logam berat di sekitar pelabuhan.
