Abstract

This research is based on water conditions in the Village of 19 November. There are some wells that do not meet the standards of clean water issued by the Ministry of Health of the Republic of Indonesia Number 492/Menkes/Per/IV/2010.  The purpose of this study was to determine the quality of shallow groundwater (wells) in 19 November Village. Based on regulations, the parameters measured consist of physical and chemical parameters.Physical parameters consist of odor, color, taste, temperature, and total dissolved solids, while chemical parameters consist of pH, BOD, and COD.  The data in this study were collected using observation techniques and laboratory analysis. Furthermore, the data is analyzed using descriptive statistics and the storet method. Based on the results of the analysis, it was found that the quality of shallow groundwater in 19 November Village was in the moderately polluted class and did not meet the standards. This is because the concentration of physical and chemical parameters has exceeded the set threshold.

Abstract

This study aims to analyze the factors causing flooding in Peoho Village, Watubangga District, Kolaka Regency. The type of research used in this study is descriptive research with qualitative and quantitative approaches. The data used in this study consists of rainfall data, soil type, slope gradient, land use, drainage system, flood control buildings and river conditions in Peoho Village. The data were collected using various methods including observation techniques, interviews, and documentation. Qualitative data were analyzed using qualitative data analysis according to Creswell. While quantitative data were analyzed using descriptive statistics. Based on the results of the study, the factors causing flooding in Peoho Village, Watubangga District, Kolaka Regency were caused by various factors, including moderate to high rainfall intensity. Another factor that causes flooding is the type of chromic latosol soil. This type of soil has a clay texture and small pores so that it quickly becomes saturated and water is difficult to absorb into the soil. The slope of the slope in Peoho Village which is dominated by flat and gentle slopes also contributes to the occurrence of flooding. Land use factors dominated by plantation land and a drainage system that does not function properly are also factors that cause flooding in Peoho Village.
