Abstract

The increasing mining activities have led to the problem of acid mine drainage (AMD) pollution. A method that combines biochar treatment as an adsorbent with wetland sediment treatment as a source of sulfate-reducing bacteria is used to address AMD effectively. This research aimed to determine the ability of biochar in combination with wetland sediment treatment to reduce sulfate and heavy metal content in acid mine drainage wastewater. This research was conducted on a laboratory scale in an AMD wastewater treatment reactor with the following treatments of biochar mixed with wetland sediment. Observations included sulfate content, pH, and heavy metal content. Scanning electron microscope (SEM) analysis was also performed on the biochar. SEM observations revealed the presence of small, dense, and irregularly shaped pores on the surface of the biochar. The results on day 30 showed that biochar mixed with wetland sediment was able to reduce sulfate concentration by 74.19% and reduced Pb by 73.79%, compared with treatment sediment only to 64.81% sulfate concentration and reduced Pb by 53.85%, treatment biochar only had reduced sulfate of 46.90% and reduced Pb by 58.67% and control 1.79% sulfate concentration and reduced Pb by 1.87%.

Abstract

Tulisan ini memberikan informasi mengenai pengaruh penggunaan lahan di Sulawesi Selatan terhadap kandungan unsur hara nitrat dan fosfat di perairan serta kualitas rumput laut Kappaphycus alvarezii yang dipelihara di wilayah pesisir. Pengumpulan data dilakukan di tiga lokasi pantai yaitu Marang di Kabupaten Pangkajene, Sanrobone di Kabupaten Takalar dan Sajoanging di Kabupaten Wajo. Penelitian ini mengukur beban limbah nutrien dari sungai di tiga lokasi dan mengukur pengaruhnya terhadap konsentrasi nitrat dan fosfat di perairan serta klorofil-a, kandungan karagenan, kadar air dan kadar abu pada rumput laut yang dipelihara di perairan pantai. Hasil penelitian menunjukkan bahwa penggunaan lahan berhubungan dengan besarnya beban hara, pada lokasi Sajoanging yang dominan penggunaan lahan pertanian menghasilkan beban nitrat dan fosfat yang tinggi, sedangkan pada lokasi lain relatif lebih rendah. Kandungan unsur hara ini mempengaruhi kondisi oseanografi dan kualitas Kappaphycus alvarezii yang dibudidayakan

Abstract

Hard coral Porites lutea is an animal that lives on the ocean floor. This species may live for years and accumulate heavy metals from its surrounding environments. The aims of this study was to know accumulation of heavy metals (Pb, Cd, and Cu) pollution by Porites lutea at different islands in Spermonde Archipelago waters. This study used field surveys around Laelae, Bonebatang and Badi Islands of South Sulawesi. Field parameters measured were oceanographic parameters, metals in water and sediment. Hard coral was extracted using nitric acid, then measured its heavy metal levels using Atomic Absorption Spectrophotometer. Several field parameters such as temperature, salinity, turbidity, pH and dissolved oxygen indicated no differences at each location, whereas the difference was observed in the values of Total Suspended Solid and dissolved oxygen. The results showed the accumulation of heavy metals in the skeleton of Porites lutea was Pb>Cu>Cd and Laelae>Bonebatang>Badi Island.

Abstract

Marginal coral reefs are located in a limited aquatic environment, causing coral organisms to live under threat and only certain species of coral are able to survive. Porites lutea is one species of coral that is able to live in normal and marginal coral reef conditions. The purpose of this study is to determine the ecology of Porites lutea, the physiological ability of Porites lutea's Productivity (P) and Respiration (R), coral reef habitat conditions and environmental factors that affect the distribution of Porites luteal in normal and marginal locations. This study used the belt transect method, measurement of coral colony volume, physiological productivity (P) and respiration (R), transect picture for substrate cover and coral reef conditions and CTD to measure environmental indicators such as temperature, salinity, turbidity, chlorophyll and DO. The results shows that the density of Porites coral is higher at normal coral reef locations (Pak Kasim), the highest volume range is 25-100 cm3, with the largest size in the 451-475 cm3 class. P/R values ​​is higher at normal coral reef sites, especially in reef slope areas. Coral reef habitat cover is dominated by abiotic components with poor coral reef conditions in marginal and normal environments. Water temperature was significantly different (P=0.039) between two normal and marginal locations with a range of 27.08 - 27.51 oC, Salinity was significantly different (P=0.145) with a salinity 33.44ppt at normal locations and 32.88 ppt at marginal locations. The chlorophyll and oxygen number was not significantly different between the two locations, the range of chlorophyll 0.03 – 0.15 mg/L and oxygen 2.49 – 5.23 mg/L. The turbidity factor was significantly different between locations (P=4.86E-07) where the marginal location in Sample was more turbid than the normal location in Pak Kasim. This study shows that there are differences between normal and marginal waters in environmental conditions and physiological reactions of Porites lutea, but this coral is able to survive to show their resilience to environmental stresses.  Keywords: Coral physio-ecology, Porites lutea, P/R ratio, marginal coral reefs.

Abstract

This study aims to determine the distribution and relationship between the concentration of cadmium metal (Cd) and total organic matter (TOM) in sediments in the Tallo estuary, Makassar City. The study collected sediment samples from 12 points, distance of 500m between points sampling. Furthermore, 12 sediment samples were analyzed for Cd and TOM concentrations in the laboratory. The results of measurements of Cd metal in sediments showed concentrations ranging from 0.001 - 0.037 mg/kg. The concentration of Cd metal found was still in the low category. While the concentration of TOM in sediment ranges from 6.7 -30.3%, indicating a low concentration. The distribution of Cd and TOM showed that the farther from the estuary, the lower the concentration. Based on the results of the regression test, the relationship between Cd and TOM concentrations was 80.1%. This shows that the accumulation of Cd metal in Tallo River sediments is strongly influenced by the concentration of organic matter.

Abstract

Tanete Rilau Subdistrict in Barru Regency is a coastal area facing environmental pressures due to anthropogenic activities such as settlements, fishponds, and coastal development. This study aims to analyze the diversity of macrozoobenthos as a bioindicator of water conditions in the area. The research was conducted in March 2026 at three observation stations: the fishpond area (Station 1), mangrove ecosystem (Station 2), and settlement area (Station 3). The results found 8 species of macrozoobenthos from the phylum Mollusca (7 species of Gastropods and 1 species of Bivalvia), with a total of 61 individuals. The abundance of individuals ranged from 3–28 ind/m², with the highest abundance at Station 1 (28 ind/m²) and the lowest at Station 3 (3 ind/m²). The diversity index (H’) ranged from 0 to 1.32, categorizing the water quality as low to moderate. Station 2 showed the highest diversity (1.32), while Station 3 showed single species dominance by Clypeomorus pellucida with a dominance index (C) of 1. Sediment analysis showed dominance of fine to very fine sand fractions with total organic matter content (TOM) ranging from 5.01% to 34.88%. PCA analysis confirmed that variation in environmental conditions is controlled by the interaction of temperature, salinity, pH, DO, and TOM, which directly affect the macrozoobenthos community structure at the research sites.
