Abstract

The estuary area of the Tukad Badung river has the potential to experience heavy metal pollution because of its location for various domestic and industrial wastes also has dense shipping activities around it. This study aims to identify the heavy metal content of Cd and Zn in water, sediment, root, and leaf samples of Sonnetaria sp. that grows in the area. The results obtained from the analysis of the heavy metal content of Cd and Zn in water samples were 0.006 mg/L and 0.014 mg/L. The results of the analysis of heavy metal content of Cd and Zn in sediment samples were 0.406 mg/kg and 15.462 mg/kg, respectively. This shows that water and sediment samples are still below the applicable quality standards. The Bioaccumulation Factor (BCF) value shows that the roots and leaves of Sonnetaria sp. can accumulate heavy metal Cd by 0.034483 and 0.041872 and accumulate heavy metal Zn by 0.011059 and 0.016751. The calculation of Translocation Factor (TF) of Cd metal of 1.214286 and Zn of 1.51462 shows that Sonnetaria sp. belongs to the category of phytoextraction (TF>1). Based on the Igeo index, the estuary area of the Tukad Badung river is classified as unpolluted to moderately polluted by heavy metals Cd (Igeo: 0.436517) and not contaminated with Zn metals (Igeo: -2.76359).

Abstract

Staphylococcus epidermidis infections of the skin can cause boils, itching and long-lasting sores. Currently, around 75% to 90% of S. epidermidis infection cases are resistant to the antibiotic methicillin. Thus, this becomes a concern in the health sector. This research aims to discover a new method to treat S. epidermidis infection by using lactic acid bacteria as its opponent, so that the use of antibiotics can be reduced. The physical test includes confirmation of Lactic Acid Bacteria (LAB), inhibition test of lab on S. epidermidis, lotion formulation, organoleptic and homogeneity test of lotion, lotion hedonic test, LAB total plate count test in lotion, and data analysis using Microsoft Excel, Statistical Program Service Solution (SPSS), and ANOVA test. Lactic acid bacteria isolates were obtained from previous research stocks and tested for their ability to inhibit S. epidermidis in vitro. These lactic acid bacteria were added to the lotion. The favorability level of consumers to the lotion was also tested. The results indicated that lactic acid bacteria were able to inhibit the growth of S. epidermidis and remained effective until the seventh day. In addition, respondents provided a positive response to the physical quality of the lotion that contained lactic acid bacteria.
