Abstract

Water is a source of necessity for humans. Water quality is very important to be considered as the source of clean water. Some people in Maros Baru District use ground wells as the source of water needs. Therefore it is important to know the physical quality and pH level of shallow wells and to know the worthiness of shallow wells in Maros Baru District with reference to Permenkes No.492/ 2010. This study examined the feasibility of water based on the physical quality and the pH level of water taken from shallow wells. The research was carried out directly in field with 14 sampling points scattered in the north, east, south, west and at the center of field. The method in observing pH value is by litmus paper and observation on the physical condition of water, well depth, well diameter and surface level of water. The result shows there were 2 locations with saltwater taste, as the location is near from the sea and rivers, while turbidity of the water influenced by condition of surround environment that was not properly maintained. From data processing, it can be concluded that as many as 5 of the 14 sampling points did not meet the eligibility standards of Permenkes No.492/2010 to be used as a source of clean water intended for drinking water.

Abstract

The purposesof this study are to see whether there are differences in mathematical analogical abilities between the class that was taught using Realistic Mathematics Education (RME) and class that was taught using expository learning, to see whether there are differences in mathematical analogical abilities of students who have high, medium, low habits of mind  taught using Realistic Mathematics Education Learning(RME), and to see whether there is an interaction between the use of Realistic Mathematics Education Learning( RME) on habits of mindand students' mathematical analogical abilities. This research is experimental, specifically thequasi-experimental design. The two-way ANOVA was used to analyze the data. Based on the results of the study, it can be concluded that: 1) there are differences in mathematical analogical abilities between the class that was taught using Realistic Mathematics Education (RME) and class that was taught using expository learning; 2) there are differences in mathematical analogical abilities of students who have high, medium, lowhabits of mind taught using Realistic Mathematics Education Learning(RME); 3) there is no interaction between the use of Realistic Mathematics Education Learning(RME)on the habits of mind and students' mathematical analogical abilities.
