Analisis Perbedaan Pada Uji Kualitas Air Sumur Di Kelurahan Madidir Ure Kota Bitung Berdasarkan Parameter Fisika

: Limited availability of raw water is one of the problems encountered in the provision of water services in Indonesia. The purpose of this study is to determine the difference in the quality of well water within 0-100 meters and within 101-200 meters from the beach by measuring physical parameters, i.e.unclearness. The number of samples in this study were 65 wells owned by residents in the Village of Madidir Ure and from those wells there are 25 with a distance of 0-100 meters and 40 with a distance of 101-200 meters from the beach.The parameters were observed referring to the Regulation of the Minister of Health of Indonesia Number 479/Menkes/Per/IV/2010 about the Terms and Water Quality Monitoring, including the physical parameters such as unclearness measured by using turbidity. Data collection methods used in this study is a cross sectional and the laboratory analysis was done in “Badan Teknik Kesehatan Lingkungan (BTKL)” Manado. The results, show water quality from the well within distance of 0-100 meters exceeds a set of maximum levels of more than 5 NTU, while the result of the water quality within 101-200 meters does not exceed the maximum of 5 NTU. Conclusion: there is a difference in the quality of water in the Village of Madidir Bitung City Ure taken from the well within a distance of 0-100 meters and the well within 101-200 meters from the beach
