Abstract

This research aims at revealing the process of making the indicator of acid basesfrom the rind of kesumba fruit (Bixa orellana L.), the changes of colour it produces, thebest solvent among ethanol, acetone, and ethyl acetate solvents used in the making ofacid base indicator and the way to use the indicator.The research was conducted in the analysis chemistry laboratory of the Faculty ofMathematics and Natural Sciences of Yogyakarta State University from February up toMay, 2010. the research methods include producing the acid base indicator from thepowder made of the rind of kesumba fruit and making pH route.The results of the research are 1). pH indicator of acid base can be made by usingthe pigment contained in the rind of kesumba fruit. The liquid indicator is made bydissolving the clean and thinly sliced rind kesumba fruit with solvent. The solution isleft for a night in order that all pigments can dissolve perfectly. The extract is then keptin a refrigerator. 2). The change of colour in the solvent that has been tested by using theliquid acid base pH indicator can be observed so that the pH route can be produced. ThepH route can be used by matching the change of colour in the solvent that has beentested by using the liquid indicator so that the pH solvent can be found. 3). The acetonesolvent proves to be the best solvent in the making of acid base indicator from the rindof kesumba fruit powder. The pH route of the indicator is: pH 2 – 7: pale yellow; pH 8 – 10: light brown; pH 11 – 12 : dark brown. 4). The liquid indicator is used by expelling 2 – 3drops of indicator into the small portion of the solvent and the change of colour isobserved. It the indicator shows pale yellow, the solvent is acid, whereas pH over 10 isindicated as dark brown in the indicator.Key words : kesumba, pH indicator, pH

Abstract

This research is aimed at finding the effectiveness of consumption meter whichcan monitor the fuel consumption of four wheeled vehicles, and also finding therelationship between the driving behavior with fuel consumption as well as finding therelationship between the wasteful fuel consumption and the car condition. Consumptionmeter is a means of monitoring the fuel consumption that drivers can use as one of themedia to help them drive the cars with economical fuel consumption.This research started with producing an instrument in the form of consumptionmeter and then accuracy test, precision test, range and response of consumption meterwas initiated by doing the measurement and collection of data to programmicrocontroller ATMEGA8535. The next step is the effectiveness test conducted step bystep. After this the data were collected. The data are in the form of the amount of fuelconsumed by the car driven the driver who did not look at the tool while driving and theone consumed by the car driven by the driver who looked at the tool while driving. Thedata also include the amount of fuel consumption before and after tune up was done.After the data were complete, a statistic test was applied.The result of testing Consumption Meter indicates that this tool shows a high levelof effectiveness. In other words, it can be effectively used to control the fuelconsumption. Furthermore, the behaviour of the drivers is closely related to the fuelconsumption in that the better the driving is, the more economical the fuel consumptionis. In addition, there is a close relationship between the wastefulness of the fuelconsumption and the early detection of the four wheeled vehicles’ condition. It can besaid that the fuel consumption reflects the condition of the vehicles because the worsethe condition of the vehicle is, the more wasteful the fuel consumption is.Keyword: Effectiveness, consumption meter, fuel consumption control, car, condition
