The influence of fuel premium and pertamax with the time frame service of a motor vehicle

CHAPTER I

INTRODUCTION

 

I.1 BACKGROUND OF STUDY

            Statistics is the study of how to plan, collect, analyze, interpret, and present the data. In short, statistics is a science that deals with the data. The term ‘ statistics ‘ (United Kingdom: statistics) in contrast to ‘ statistics ‘ (statistics). Statistics is the science that deals with the data, statistics are data, information, or the results of the application of statistical algorithms at some data. Of data collection, statistics may be used to summarize or describe data; This is called descriptive statistics. Most of the basic concepts of statistics assumes probability theory. Some statistical terms such as: population, sample, sample unit, and probability.

            Many statistics are applied in different disciplines, natural sciences (e.g. astronomy and biology and the social sciences (including psychology and sociology), as well as in the fields of business, economics, and industry. Also used in government statistics for a variety of purposes; population census is one of the most known procedure. Other statistical applications which are now popular is a procedure the poll or poll (conducted before the elections), as well as a quick poll (a quick count election results) or the quick count. In the field of computing, statistics can also be applied in pattern recognition and artificial intelligence.

            We took a sample of cases collected in real and can be analyzed on an ongoing basis and presenting that data in writing this paper. Here we sampled as much as 12 which can be analyzed using the method of% u201CDistribusi% u201D t. We use the t Distribution for sample taken & lt; 30.

 

 

 

 

I.2 PROBLEM FORMULATION

  • What effect obtained from different fuel use?
  • What impact of fuel use used by each consumers?
  • When consumers do service to their vehicles with fuel use they use each?
  • Why consumers chose fuel use rates differ by premium more? Anyone were parties use this?
  • How we examine the case using 12 samples?

            So, it can be said whether there is influence gained from the use of different fuels. Usually from the vehicle’s engine, the fast is broken or not. Consumers are usually doing a service by an average of 1 month. Consumers are also different in choosing fuel is usually due to some factor that is usually based on economic factors and put aside the level of quality. And we resolve the problem by using the t distribution.

 

I.3 LIMIT PROBLEM

            A kind of fuel oil gasoline is a general name for several species of bbm that are reserved for machinery by burning it with a ignition. In indonesia there are some kind of fuel type of gasoline having value the quality of burning different. The value of the quality of a kind of bbm gasoline this count based on the value of ron ( randon otcane number ). Based on ron was then bbm gasoline differentiated into three types namely:

– Premium ( ron 88 ): premium is kind of the distillate fuel oil colored a clear yellowish. A yellow color was caused by the presence of coloring substance an additional ( dye ). The use of premium in general is to fuel bermesin gasoline motor vehicle as: cars, motorcycles, outboard and others. Fuel is often also called motor gasoline or petrol.

– Pertamax (RON 92) : intended for vehicles that require high-octane fuel use and no lead (unleaded). Builtin is also recommended for vehicles produced above 1990 especially who have used the technology on par with electronic fuel injection and catalytic converters.

– Pertamax Plus (RON 95) :  The type of FUEL it has to meet the standards of performance International World Wide Fuel Charter (WWFC). Intended for advanced technology vehicles that require high-octane fuel use and environmentally friendly. Builtin Plus is recommended for vehicles that have a compression ratio & gt; 10.5 as well as using technology Electronic Fuel Injection (EFI), Variable Valve Timing Intelligent (VVTI), (VTI), Turbochargers and catalytic converters.

            In this paper we will discuss his work on as much detail as possible from the influence of premium fuel and motor vehicles especially against builtin (motorcycles), how many periods of service vehicles due to the use of premium fuel and the builtin. Similarly, many as a result of the use of premium and builtin on motor vehicles.

I.4 RESEARCH PURPOSES

  • To know what effect obtained from fuel use different.
  • To know when consumers do service to their vehicles with fuel use they use each.
  • To know why consumers choose fuel different with use rates premium more.
  • To knowing how we were to scan the case by using samples some 12.

 

I.5 Researcher Methodology

            In writing a piece of writing is one method, we use namely distribution t because samples used in this distribution & it; 30. Where we gather in real and can be analyzed twelve people that we will make as samples into writing this paper.

II.1 THEORETICAL

            A kind of fuel oil gasoline is a general name for several species of BBM that are reserved for machinery by burning it with a ignition. In indonesia there are some kind of fuel type of gasoline having value the quality of burning different. The value of the quality of a kind of BBM gasoline this count based on the value of ron ( randon otcane number ). Based on ron was then BBM gasoline differentiated into three types namely:

– Premium ( ron 88 ): premium is kind of the distillate fuel oil colored a clear yellowish. A yellow color was caused by the presence of coloring substance an additional ( dye ). The use of premium in general is to fuel bermesin gasoline motor vehicle as: cars, motorcycles, outboard and others. Fuel is often also called motor gasoline or petrol.

– Pertamax (RON 92) : intended for vehicles that require high-octane fuel use and no lead (unleaded). Builtin is also recommended for vehicles produced above 1990 especially who have used the technology on par with electronic fuel injection and catalytic converters.

– Pertamax Plus (RON 95) :  The type of FUEL it has to meet the standards of performance International World Wide Fuel Charter (WWFC). Intended for advanced technology vehicles that require high-octane fuel use and environmentally friendly. Builtin Plus is recommended for vehicles that have a compression ratio & gt; 10.5 as well as using technology Electronic Fuel Injection (EFI), Variable Valve Timing Intelligent (VVTI), (VTI), Turbochargers and catalytic converters.

II.2 CALCULATION

            We have been on research with the test influence between a fuel used with a term of service to the vehicle motorcycles and take a random sample as many as 12 a person who uses fuel type different. A period of time service that is performed by each cycler a motor is in to do service by using fuel type different is as follows:

By using the level of significance 2 %, can it be deduced that there is a significant difference between the use of fuel premium and pertamax?

Finalization :

  1. Hypothesis testing is conducted to determine what happened to the average  difference is a two-sided test.

Ho : µ1 – µ2 = 0    Ha : µ1 – µ2 ≠ 0

 

  1. the critical Value For the test side, to determine the value t table, the value α = 0,02 we share two being  0,02/2 = 0,01

degrees of freedom  d.f. = n1+n2-2 = 8 + 4 – 2 =10

 

Thus the value of t is the sample t (0,01;10) = 2,764

The rejection only happens if the Ho | t table | > 2,764

Then value t sample is t

    Sx1-x2            53,30            53,30

 

4              Conclusion

Because t samples = -0,035 smaller than value t ( 0.01; 10 ) = 2,764, we accept Ho. Conclusions, no a significant difference between discharging fuel type pertamax and premium in influence period service.

 

 

 

 

 

 

 

 

 

CHAPTER III

CONCLUDING CHAPTER

 

III.1 CONCLUSION

            From the analysis that we do can be concluded that:

  • no influence significant between discharging fuel type pertamax and premium in influence period servicenya.

 

  • fuel use not affecting time service motor vehicles.

 

  • observation, according to the use of premium more used because a very affordable price to the society compared with pertamax.

 

  • research with the use of samples some 12, is to use t-student to know the results obtained in a research.
