Abstract

In this study, researchers used a type of motor 4 stroke 125 cc Suzuki Shogun brands with the year of manufacture 2010. Data collection exhaust emission test performed when the motor before and after wear electrolytes with various mixtures of electrolyte. Data were taken by the engine rotation changes from 1,000 RPM to 4,000 RPM. The highest yield for CO occurred at 4000 RPM with an electrolyte mixture of distilled water and 1 ½ tablespoons of KOH with a value of 1.04%. While the lowest CO occurred at 3,200 RPM when the motor was not used electrolysis with a value of 0.07%. For HC was highest at 1,000 RPM when the motor was not used electrolysis the value of 382 ppm. While the lowest occurred in HC 4,000 RPM with a mixture of distilled water and KOH electrolyte ½ tablespoons of as much as 20.33%. The highest value of CO2 was in the second electrolyte mixture, 8.2%. It was the first mixture between KOH electrolyte and distilled water. In the other hand, the lowest value of CO2 valuewas around 4.1%. It happened for the second time mixture while the motor electrolysis only distilled water and electrolytes itself.

Abstract

This study aims to determine the level of acidity in the rainwater in the industrial area of East Jakarta. The research was done by using a multimeter (Waterproof Tester). With these tools, it can be seen pH and temperature in the rainwater. The results shown that the rainwater in the area of Bekasi tends to be normal because it is still in the average and standard. Although these areas are industrial areas, airports, and many transportation passes, the industrial area still have green places.

Abstract

The purpose of this study is to find out the level of acidity (pH) and electrical conductivity (EC) in the ground water in Residential, Office Building and Industrial Area in Bogor. This study used pH meter to determine the level of acidity and EC meter to find out the electrical conductivity. The method in this research was to collect ground water samples randomly in several places in Bogor area. The result of this research showed that the ground water in Bogor area was categorized as normal, because the pH was in range of 7.23 to 7.51
