Analysis of the Quality of Examination of Cleaning Workers' Feature Samples Using the Saturated NaCl and ZnSO4 33% Method

Worm infections are caused by one of the soil-borne intestinal nematodes called Soil
Transmitted Helminths (STH). One of the agents of soil pollution is garbage. Cleaners are
among the workers who have a high risk of contracting helminthiasis. The purpose of fecal
examination is for early detection of helminth egg infection, especially intestinal nematodes of
the Soil Transmitted Helminths (STH) group. The method used is flotation with saturated NaCl
solution and 33% ZnSO4. This study is an observational study aimed at comparing the quality
of the two reagents that can be used in the examination of Soil Transmitted Helminths (STH)
eggs. The study used 30 samples of feces of janitors and 3 repetitions of each sample were
carried out with 2 methods to determine the quality of the results. The results of Soil
Transmitted Helminths (STH) eggs with saturated NaCl reagent with a mean of 8.86, while
ZnSO4 33% with a mean of 20, the difference from the 2 methods is 11.43. In this study using
the data normality test and the Mann-Whitney U test, the results obtained Asymp. Sig. (2-
tailed) 0.034. The value of Asymp. Sig (2-tailed) <0.05 concluded that there was a significant
difference between the quality of the examination of Saturated NaCl and 33% ZnSO4. The
conclusion of this study is that the most effective is the use of ZnSO4 33% for the flotation
method with an average result of 20
