Abstract

Sungsang Village is located at the mouth of the Musi River making this area dense with settlements and transportation activities, this contributes to damage and results in decreased water quality. This study aims to analyze the concentrations of Pb and Cd in water, sediment and white shrimp (Penaeus merguiensis) and examine the level of accumulation of Pb and Cd through the BCF values of Pb and Cd in white shrimp (Penaeus merguiensis) in water and sediment in the waters of Sungsang I Village. Results the study showed that the average concentration of Pb in water in the waters of Sungsang I Village was 0.104 mg/L, exceeding the threshold value in Kep.Minister of State for the Environment No. 51 of 2004. The average Pb content in sediments is 24.892 mg/Kg, still below the quality standards of the Guidelines for the Protection and Management of Aquatic Sediment Quality in Ontario. The average concentration of Pb in jerbung shrimp is 0.809 mg/Kg, this value exceeds the limit set by BPOM. The results of the Cd test showed that the average water content, sediment, and jerbung shrimp were 0.013 mg/L, 0.174 mg/Kg and 0.127 mg/Kg. The BCF Pb value of shrimp-sediment was 7.779 and BCF Pb of shrimp-sediment was 0.033. The BCF Cd of shrimp-sediments was 9.769 and the BCF Cd of shrimp-sediments was 0.730. The Pb and Cd bioconcentration values of the jerbung shrimp (Penaeus merguiensis) in water and sediment are included in the low accumulative category, because the BCF value is <100.

Abstract

The Sungkai plant has become a trending topic lately because of its benefits, which are believed by some people to be used in preventing the transmission of the COVID-19 virus by boiling some of its leaves using water. The purpose of this research was to examine the active ingredients contained in sungkai leaves (Peronema canescens Jacks) which were extracted by infundation (water solvent) and extracted by maceration (methanol solvent). The method used in this study is a qualitative chemical analysis. Phytochemical screening in this study, namely the alkaloid test (using Mayer, Wagner, and Dragendroff reagents), flavonoid test, tannin test, saponin test, steroid test, terpenoid test. Based on the results of the study, the results of the phytochemical screening of the methanol extract of sungkai leaves by maceration showed that all of the active compounds contained were positive, while the positive infundament extract contained flavonoids, steroids, terpenoids, tannins, saponins, but negative alkaloids.

Abstract

Biomassa is a product produced by plants, composed of hydrocarbon elements (C, H, O, and N) to form cellulose, hemicellulose, and lignin compounds consisting of active groups in the form of hydroxyl (-OH) and carboxylic (-COOH). This group can bind heavy metals. The potential distribution of biomass is found on the islands of Kalimantan, Sumatra, Java, Sulawesi, and Irian Jaya. The impact of the heavy metal Cd is in the form of kidney damage, bronchitis, gastrointestinal gas irregularities, and cancer. Impact of Pb has an impact on liver and kidney disease, gastrointestinal gas damage, and disrupted child growth. Impact of Mn has an impact on inhalation or damage to the respiratory system. Impact of Hg has an impact on respiratory system damage and flows plasma poisoning. Impact of Zn has a corrosive effect on the skin, and damages the respiratory membranes. Impact of Ar causes bronchitis and dermatitis. Factors that affect the adsorption of heavy metals by bioadsorbents, namely: adsorbent, grain size, degree of acidity, contact time, concentration, and porosity.
