5. Price- Demand 2016 IDR 7,050 Number of Requests Fuel (million kiloliters) 30.41 2017 IDR 7,500 2018 IDR 7,800 Year Fuel price ( Liters) 2015 IDR 8,400 33.78 35.00 31.62 2019 IDR 7,650 32.80 Data collection, Presentation of data and Data processing Qd = a- bp Equation model Fuel Price Number of Fuel Requests ECONOMETRICS ECONOMIC STATISTICS MATHEMATICS

6. Theory: Law of Demand => Y, X => X1, X2, X3 , Ho: There is no effect between price increases Fuel Oil (BBM) on request BBM. Ha: There is an influence between increasing material prices Burn Oil (BBM) with fuel requests. 1 < , Yi = + 1 + Presenting Hypotheses based on Theory Mathematical model: A Single equation model A multiple equation model Y Y = fuel demand X = fuel price Machine Translated by Google

7. Mathematical model of consumption function: – Deterministic in nature –Exact relationship between the number of requests Fuel and fuel prices In practice, the quantity demanded is not only influenced by price Other influencing factors: Income Price of other goods Preference Machine Translated by Google
