Abstract

Escherichia coli is the main pathogenic bacteria which causes diarrhea in humans and the fourth highest cause of death which occurs all age groups. Salmonella sp is the cause of typhoid fever and findings of 350-810 cases each year. Diarrhea and typhoid fever are closely related to the consumption of raw vegetables, such as lettuce. This study aimed to analyze the contamination of E. coli and Salmonella sp on some lettuces in Traditional Markets of Banyuwangi Regency. This research was an analytic descriptive study using a cross-sectional design at the Laboratory of Microbiology, STIKES Banyuwangi from 6 to 11 June 2022 using 6 lettuces as research samples which were selected by accidental sampling. All (100%) lettuce samples in this study were contaminated with >1,100 CFU/ml E. coli. All (100%) samples in this study were positively contaminated by Salmonella sp with various contamination number, such as: 0.82x104; 0.47x104, 1.90x105, 2.05x106, 1.00x105 and 1.25x106 CFU/ml, respectively. All six lettuces obtained from the Traditional Market of Banyuwangi Regency did not meet the microbiological quality specified by SNI, indicating that they were not suitable for  direct (raw) consumption.

Abstract

Mercury (Hg) is a metal that is commonly found in water and has toxic properties, so it is very dangerous for human health and the environment. Mercury in the environment can come from gold mining activities such as in Pesanggaran Village, Banyuwangi. Based on information from the surrounding community, the waste disposal flowed into the river and it was feared to affect the quality of river water in this area. This study aimed to analyze the mercury level in the river water using the UV-Visible Spectrophotometer method, where river water samples were taken from the upstream, middle, and downstream parts. Determination of mercury levels was carried out at the STIKES Banyuwangi Laboratory. The results showed that the Hg content in the river water around the gold mining area of Pesanggaran Village, Banyuwangi ranged from 0.031 to 0.033 mg/L. The Hg level of river water in this area was above the threshold and it was not recommended to use as drinking, bathing, cooking or washing. However, it is necessary to analyze Hg levels using other methods, such as the AAS (Atomic Absorption Spectroscopy) method which is more expensive but more accurate results will be obtained.
