A good analysis of the pharmacy business is needed to find strategies that can be implemented to develop the business. One analysis that can be done is to analyze the factors that influence purchasing decisions. The factors to be analyzed are price, service and completeness. Data will be analyzed using multiple linear regression analysis. Based on the results of the analysis and discussion, it can be concluded that price has a negative effect on buyer decisions at Endar Farma Pharmacy with a drug price regression coefficient of 0.178; The service and completeness of the drug has a positive influence on the buyer's decision at Endar Farma Pharmacy, with a service regression coefficient value of 0.326 and a regression coefficient value of drug completeness of 0.401. The three variables above are very influential on the decision of Endar Farma Pharmacy buyers, this can be seen from the percentage obtained from these 3 variables of 54.3%.]]>

<![CDATA[The Consumer Price Index (CPI) is an economic indicator that can provide information regarding developments in prices of goods/services. CPI is one of the factors that can measure inflation. According to the information provided, inflation pressure is influenced by the food, beverage and tobacco sectors and is one of the mainstays in providing a major contribution to economic growth. Every month the CPI can increase or decrease so data from previous times is used to see predictions for the present so time series data is used. Prediction of CPI time series data can use one of the mathematical techniques, namely Markov chain analysis. Markov chain is a method that studies the properties of a variable in the present in an effort to estimate the properties of the same variable in the future, therefore Markov chain analysis is suitable for use in predicting CPI. In this research, it was applied to CPI data for January 2018 to June 2022. After conducting the analysis, it was concluded that in the following months the opportunity for CPI in categories above the basic price was greater than the opportunity above the basic price. So it is hoped that the results of this analysis can help the government stabilize the CPI in the Food, Miniman and Tobacco sectors]]>
