Abstract

Background: Illegal gold mining in Buru Regency uses the heavy metal mercury toprocess gold material, so it can pollute the environment, including aquatic biota such asmangrove crabs (Scylla serrata) and mangrove snails (Telescopium telescopium). The aimof this research is to analyze the amount of mercury concentration and the level of pollutionin mangrove crabs and snails as a result of illegal gold mining in Buru Regency.Methods: Research samples were taken at the Waelata River Estuary and the AnahoniRiver Estuary. For mercury analysis, 8 mangrove crabs and 16 mangrove snails weretaken. Analysis of mercury concentration using the AAS Cold Vapor method.Results: The results showed that the heavy metal mercury was detected in mangrovecrabs and mangrove snails. The concentration of mercury detected is still below the qualitystandard set based on heavy metal contamination (SNI) No. 7387 of 2009, specifically forthe heavy metal Hg in shellfish (bilvalves), mollusks and sea cucumbers, shrimp and othercrustaceans at 1.0 mg/kg (ppm).Conclusion: Illegal gold mining in Buru Regency has an impact on mercury concentrationsin mangrove crabs and mangrove snails, but the value is still below the specified qualitystandards. However, consumption of mangrove crabs and mangrove snails that live aroundgold mining areas in Buru Regency must be limited, considering the nature of mercuryaccumulation.

Abstract

Background: The production of seaweed cultivation in Saliong Hamlet, Batu Boy Village, hasdecreased, and there have even been crop failures in the last five years. For this reason, an analysisof the factors suspected of influencing the failure is needed. The purpose of this study was to analyzethe quality of seaweed cultivation waters in Saliong Hamlet, Batu Boy Village by using physicalchemical factors of the waters.Methods: There are three stations used for sampling. The physical and chemical parameters of thewaters measured include temperature, brightness, current speed, water depth, pH, salinity, TDS,DO, BOD, phosphate, heavy metal mercury (Hg) and cyanide. To determine water quality, the resultsof measuring physical-chemical water parameters will be compared with sea water quality standardsfor marine biota and quality standards for seaweed cultivation based on experts in the field.Results: The research results showed that temperature, depth, TDS, phosphate and heavy metalmercury did not meet quality standards. While the parameters of brightness, turbidity, currentvelocity, pH, salinity, DO, BOD and cyanide are still in accordance with the quality standards forseaweed cultivation.Conclusion: The quality of the waters in the seaweed cultivation area in Saliong Hamlet still meetsthe quality standards and some does not comply with the quality standards. The occurrence ofseaweed harvest failure can be caused by the presence of physical-chemical factors in the watersthat are less supportive.

Abstract

Background: Seaweed is widely cultivated in coastal areas of Indonesia, one of which can be found in Kayeli Bay, Buru Regency. One of the problems faced by farmers in cultivating seaweed in this area is that there is no division of suitable areas for cultivation land in the form of thematic maps, especially using physical-chemical parameters of waters. Methods: This activity includes several stages, namely location survey, data collection or collection and preparation of a database. Measurements of physical and chemical parameters of waters are carried out directly in the field (in situ) and in the laboratory (ex situ). The measurement parameters include temperature, brightness, wave height, current speed, pH, salinity, DO, nitrate and phosphate. To create a thematic map of land suitability, the ArcGis application was used. Results: Most of the physical and chemical parameters of the waters are still suitable for seaweed cultivation, except for temperature and phosphate. The results of land suitability evaluation/analysis based on water physical-chemical parameters produce two land suitability categories, namely suitable (S2) and very suitable (S1). The category corresponds to an area of ​​110.2 ha or 29% and very corresponds to an area of ​​269.8 ha or 71%. Conclusion: The thematic map of Kayeli Bay waters, Buru Regency shows that the suitability of seaweed cultivation land is divided into two categories, namely suitable at 29% and very suitable at 71%. However, the temperature and phosphate parameters at the time of measurement were in the category not suitable for seaweed cultivation.

Abstract

The study was conducted from August to September 2024 at the seaweed cultivation location in Kaiely Bay, with sampling at three observation stations. The method used was a survey with a laboratory approach. The parameters analyzed included phytoplankton abundance, chlorophyll-a content, and identification of pests and diseases in seaweed. The data obtained were analyzed descriptively. The results of the study showed that the abundance of phytoplankton at the three research stations was very high (eutrophic) with the highest value at Station 2 (8,133,333.33 cells/L) and the lowest at Station 3 (6,043,333.33 cells/L). Chlorophyll-a at all stations was in the eutrophic category with the highest concentration at Station 2 (0.00137 mg/L). The types of pests found at all stations were chicken fish, rabbitfish, and turtles. There were two types of bacteria found, namely station 1 pathogenic bacteria Pseudomonas aeruginosa, station 2 and station 3 types of Vibrio. Thallus morphology at station 1 was: gouging and stripping, station 2 was stripping, tip-nipping and ice-ice and station 3 was gouging, stripping, tip-nipping, and ice-ice.

Abstract

Mercury is a neurotoxic heavy metal with high bioaccumulation ability in aquatic biota, such as mangrove crabs (Scylla serrata), mangrove snails (Telescopium telescopium), and mangrove mussels (Polymesoda erosa), which are widely consumed by humans, and used as bioindicators of pollution. This study aimed to analyze the effect of mercury solution concentration and species differences on mercury absorption in the three biota. The method used was experimental treatment with mercury concentrations of 1 ppm, 5 ppm, 10 ppm, and control. Samples were analyzed using the AAS Cold Vapor method at the IPB Bogor Proling Laboratory. Data were analyzed descriptively and inferentially using two-way Anova with an α level of 0.05, followed by the Duncan Test if the hypothesis was accepted. Research data will be processed using SPSS 26.0 software. The results showed that mercury concentration and species differences influenced the ability to absorb mercury. Mangrove clams had the highest mercury accumulation compared to mangrove snails and mangrove crabs, especially in the 5 ppm and 10 ppm treatments. The highest mercury exposure occurred on the second day of observation.
