Abstract

Scavengers are individuals who gather used items or specific waste for recycling. Scavenging work has resulted in the notion that the scavenger's way of life is an unhealthy lifestyle. The environment and workplace are not conducive and are unclean, so there is a high possibility that scavengers can contract various illnesses, such as coughing, itching, diarrhea, and others. Risk factors for STH worms entering the human body are poor personal hygiene, which can be caused by not being familiar with maintaining proper hand and nail hygiene. Fingernails become a place where worm eggs are attached and can be swallowed when eaten. The purpose of this study was to determine the presence of STH (Soil-Transmitted Helminth) eggs on the fingernails and toenails of scavengers in Suwung landfill. The research design was carried out with an observational study using the cross-sectional method and the results were analyzed with Chi-Square which was carried out by assessing the relationship between the presence of STH eggs and the use of PPE while working. A total of 10 respondents were sampled for their toenails and hands. The results revealed an incidence of STH egg infection in 20% of fingernails and 10% of toenails caused by Ascaris lumbricoides and Trichuris trichiura eggs. A Chi-Square test was performed to examine the correlation between the usage of PPE and the occurrence of STH infection, and a p-value> 0.05 was obtained. Therefore, it can be concluded that there is no strong relationship between both of them.

Abstract

The aim of this research is to analyze and describe the students' needs for biology learning resources used in the eighth-grade classroom at MTsS Qasratul Jannah. The instruments used in the study include interview questionnaires with teachers, student needs questionnaires, and book analysis. Based on the interview results, it was found that the school only uses one textbook and worksheets available in the market. Additionally, 0% of students have not met the Minimum Completion Criteria (KKM) in the material on the human digestive system. The student needs questionnaire revealed that 94.7% of students face difficulties in understanding the material on the human digestive system, and 42.1% of students prefer handout teaching materials. The book analysis revealed deficiencies in the teaching materials, as they do not cover efforts to maintain the health of the human digestive system, and do not include illustrations in each topic. Based on the analysis, supporting teaching materials are needed, such as handouts that align with the students' needs
