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: Alcoholic beverages can be derived from palm sap or fruit juice. The fruit most widely used as a base for alcoholic beverages by the fermentation is generally grapes. The Gandaria (Bouea macrophylla Griff) can be used as raw material for substitute grapes for the process of making alcoholic beverages. Sugar is one of the important factors, because sugar is fermented by yeast into ethanol and CO2. The purpose of this research was to know the effect of fermentation time and types of sugar on alcohol content in gandaria(Bouea macrophylla Griff)-based drinks and organoleptic tests as a support for practicum in Ethnobotany courses. Methods: The research was conducted on 13 February-06 March 2023 at the Basic Chemistry Laboratory FMIPA and used destilation method. Results: The results showed that the combination of fermentation time and sugar type gave a very significantly different effect on each treatment. This can be seen from the results of the Least Significant Difference test where every week there is an increase in alcohol content. While, the organoleptic test showed the level of liking of the colour with the highest score of 2.9 in treatment f3g1, for the odor with the highest score of 2.9 in treatment f3g2 and for the taste with the highest score of 3.6 in treatment f2g1. Conclusion: Based on the results of the study, it was concluded that the time of fermentation and the type of sugar influenced the alcohol content of gandaria (Bouea macrophylla Griff). -based drinks
