Abstract

Water is an important natural resource in life. But the water used by the community is not guaranteed quality. Water quality is currently experiencing decline as it occurs in the Brantas River. Around Brantas River There are various activities performed by the population that can increase the amount of waste that goes into the river water. Water pollution The Brantas River can affect the surrounding water sources such as wells. The purpose of this research is to analyse the chemical quality and bacteriology of well-dug water around the flow of Brantas River in Malang Raya region and analyze the linearity of the quality of chemistry and bacteriology between water wells with Brantas River in Malang Raya area and to analyse the utilization of research results as a source of learning in the form of posters. The research is done with 2 stages, activity stage I is a research of quality water well dug around the flow of the Brantas River area of Malang Raya and activity phase II is the study of the results of the activity stage I become learning resources in the form of posters. Stage I activities are analytical descriptive research with a quantitative approach. Stage II activities are development studies using the Learning Cycle 3e model. The sampling of well-dug water and the Brantas river water are measured pH, nitrate content and total bacteria Escherichia coli using the TPC (total Plate Count) method. The data analysis techniques used are correlation analysis. According to PERMENKES No. 32 year 2017 the threshold value of Water quality indicator for PH is 6.5-8.5, nitrate 10 mg/l and total E. coli 0 cfu/100Ml. Results showed that the highest and lowest pH of water well dug are 8 and 5. Highest and lowest nitrate content of water wells is 23,12 mg/L and 6.19 mg/L. Total E. coli is 0 CFU/100ml. For water samples of Brantas river the highest and lowest PH water streams are 8 and 6. The highest and lowest content of the river water is 6.98 mg/L and 4.12 mg/L. the highest and mostrecent E. coli is 78x10³ CFU/100ML and 27x10² CFU/100ML. The result of this research being developed as a source of learning in the form of posters to that class of X at Senior High School.
