Abstract

The Kali Jagir River in Surabaya has the potential to receive domestic and industrial wastewater resulting from the activities in Surabaya city and serves as a raw water source for PDAM Surabaya. The chemical content of wastewater can include heavy metals such as Cd and Pb. This study aimed to analyze the water quality of the Kali Jagir River in Surabaya in terms of cadmium (Cd) and lead (Pb) content in 2022. The type of research is observational with a cross-sectional approach. The research object is the water of the Kali Jagir River in Surabaya, which was taken from the upstream, midstream, and downstream sections of the river with 3 replications. Data analysis was conducted to determine the water quality of the Kali Jagir River by comparing it with the Class I Water Quality Standards based on the Government Regulation of the Republic of Indonesia Number 82 of 2001. The average cadmium (Cd) content in the upstream, midstream, and downstream sections of the Kali Jagir River was 0.0005 mg/L. The average lead (Pb) content in the upstream, midstream, and downstream sections of the Kali Jagir River was <0.010 mg/L, <0.010 mg/L, and <0.012 mg/L, respectively. The cadmium (Cd) and lead (Pb) content in the upstream, midstream, and downstream sections of the Kali Jagir River comply with the Class I water quality standards. Future research is suggested to examine sediments and biota to assess the presence of heavy metals.

Abstract

Diarrheal diseases often occur in school children with a frequency of liquid bowel movements three or more times a day. Environmental and behavioural factors affect diarrhea in children. This study aims to analyze the relationship between elementary school children's behaviour and diarrhea in Berbek Village in 2024. Observational analytical research with a cross-sectional approach was conducted in three elementary schools in Berbek Village. The study population was 529 children from grade 4 to grade 6, with samples taken by stratified random sampling. Data were collected through observation and interviews using questionnaires and analyzed with the Chi-square test. The results showed that there was a significant relationship between knowledge (p=0.000), attitude (p=0.000), attitude (p=0.000) and behaviour (p=0.003) on the incidence of diarrhea. Still, there was no relationship between infrastructure facilities (p=0.891) and school policies (p=0.891). It is recommended that schools expand students' knowledge and attitudes about clean and healthy living behaviours (PHBS) with visual media that are attractive and easy to understand, and teachers provide examples of the implementation of PHBS in schools and complete school infrastructure facilities to be more adequate.
