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

Abstract

The research was aimed at improving the English speaking skills of the grade V students of SDN SamironoYogyakarta. This research focused on the implementation of TPR method to improve the students’ speaking skills.This research was a classroom action research. The subjects of the research were 19 students. The researchwas conducted in two cycles. Each cycle was divided into four steps, i.e. planning, observing, acting, and reflecting.The data were collected through interviews, observations, field notes and documentations. The data were analyzedby using a qualitative descriptive technique. The success of the research was achieved based on the criteria of thelevel of speaking confidence, ability to understand the teacher’s instructions, understanding of the lesson materials,and ability to pronounce words accurately. The improvement can be seen through the scoring rubrics with therange of 1 to 5. Level 1 indicated extremely poor quality; level 2 indicated poor quality; level 3 indicated adequatequality; level 4 indicated good quality; and level 5 indicated very good quality.The level of speaking confidence increased from level 3 in the first cycle to level 4 in the second level. Theability to understand the teacher’s instructions and learning materials was still in level 4 in both cycles. The abilityto pronounce words accurately was still in level 2 in both cycles.Keywords: Total Physical Response (TPR), speaking skills, grade V students

Abstract

With the rapid development of information and communication technologies leads the Ministry ofNational Education to conduct a basic reformation on educational books with by issuing innovationpolicies in the form of School Book Electronic (BSE) in order to provide a mass of textbooks, with low‐cost,good quality and technology. This study was aimed at finding out how the BSE policy was implementedand what obstacles were found in the field.The study listed different types of research with a descriptive qualitative approach, using in‐depthinterviews, observation, and triangulation documentation as data collection techniques. The sources ofdata in this study are the Head of Department of Education, headmasters, teachers, school staff,students and parents who were selected by using a purposive sampling technique and snowball samplingand the results of observation.The research showed SMA Negeri 8 Yogyakarta SMA and SMA Negeri 9 Yogyakarta were ready withthe necessary infrastructures to implement the BSE policy. However, the implementation of BSE policy atboth schools were not effective. This was due to the following reasons: (1) Insufficient socialization bythe government, (2) Human resources that have not been able to use particular technologies related toInternet, (3) unavailability of the management system in the use of BSE; (4) The limited collections oftextbooks that are available in BSE and the inaccessibility of BSE ; (5) Status / Quality of schools. SMANegeri 8 Yogyakarta as standard international schools and SMA Negeri 9 Yogyakarta as a nationalstandard school think that the materials in BSE only includes basic competencies (standards). So, BSE isnot suitable to support the achievement of school targets, and (6) Lack of strong legal base for BSE.There is no clarity of shared the authority, tasks and roles that must be executed by each institutionincluded in the hierarchy of National Education Ministry.Keywords: Policy Implementation, BSE

Abstract

This experimental research was aimed at determining the effectiveness of using parfume spray deodorant with lemon grass extract on Staphylococcus epidermidis bacterial activity and to find out the optimum concentration oflemongrass extract in parfume spray deodorant to reduce Staphylococcus epidermidis activity.The research method included four steps, namely preparing lemongrass (Cymbopogon nardus L.) extract,making perfume spray deodorant, conducting laboratory test, and testing within a limited audience. Thisexperiment revealed that lemongrass (Cymbopogon nardus L.) extract could potentially be used as an anti‐bacteriaStaphylococcus epidermidis. Making perfume spray deodorant from lemongrass (Cymbopogon nardus L.) extractconsisted of two steps, preparing lemongrass (Cymbopogon nardus L.) extracts and mixing the lemongrass(Cymbopogon nardus L.) extract with alcohol and propylene glycol.Inhibition test of lemongrass (Cymbopogon nardus L.) extract on the growth of Staphylococcus epidermidisused Mueller‐Hinton media order. From the test results of each lemongrass (Cymbopogon nardus L.) extract in theconcentration of 5%, 15%, and 30%, inhibition results were obtained. They were 0 mm, 0 mm, and 14 mm, whilethe inhibition of standard perfume spray deodorant in the market was 8 mm . Based on the results, it can beconcluded that the inhibition of lemongrass (Cymbopogon nardus L.) extract on the growth of Staphylococcusepidermidis was effective and optimum at the concentration of 30%.Keywords: lemongrass extract, Staphylococcus epidermidis, perfume spray deodorant

Abstract

This research was aimed at finding out (1) the optimum dosage of sapodilla extract in reducingcholesterol; (2) the optimum reaction time of sapodilla extract in reducing cholesterol.The method used in this research used two variables, dependent and independent variables. Theindependent variable in this research was the dosage of sapodilla extract and the reaction time ofsapodilla extract toward cholesterol, while the dependent variable was the decrease of cholesteroltowards the dosage of sapodilla extract and the reaction time which were given in different ways. Thisresearch was tested by using spectrophotometer method.The result of this research was the more the dosages of sapodilla extract given the greater theamount in decreasing the cholesterol was and the reaction between sapodilla extract and cholesteroloccurred after they were mixed in two and half hours.Keywords: determining the dosage, the optimum reaction time, sapodilla extract, amount of cholesterol
