Promotion is all activities carried out by the company to communicate and promote its products to its marketing targets. Several forms of promotion, known as the promotion mix, are advertising, personal selling, sales promotion, public relations, and direct marketing tools that companies use to achieve their advertising and marketing goals (Kotler & Keller, 2016).
Social media is a medium on the internet that allows users to represent themselves and interact, collaborate, share, communicate with other users, and form virtual social bonds (Rulli, 2015). Today, the practice of marketing with social media is starting to develop and is used as a strategic tool for product marketing, brand promotion, and the brand of a company. Social media is a gathering place for people who want to share information and a place to make new friends and interact with other friends online.

3.RESEARCH METHOD 3.1.Type of Research
The type of research that will be conducted in this research is explanatory research. According to Sugiyono, (2017) Explanatory Research is research that has the aim of explaining the position of the variables studied and the effect of one variable on another variable. The causal relationship in this study is to show the effect of Facebook Social Media Promotion, Product Quality and Price on Zack Krezz's purchasing decisions.

3.2.Nature of Research
The nature of the research in this study is replication. Replication research is research conducted by adopting the same variables, indicators, research objects, or analytical tools as previous research. This research is a replication study of Ekky Suti Wibisono conducted in 2019 with the title "The Effect of Product Quality, Price, and Consumer Satisfaction on Consumer Purchase Decisions". The difference in this study lies in the addition of the variables used, namely Promotion Through Social Media Facebook (X1), Product Quality (X2), Price (X3) and Purchase Decision (Y)

3.3.Population and Sample
Population Sugiyono, (2017) Population is a generalization area consisting of objects/subjects that have certain qualities and characteristics that are applied by researchers to be studied and then drawn conclusions. The population used in this study were the buyers of Zack Krezz Chips belonging to the Kreasi Sejahtera Abadi Micro, Small and Medium Enterprises with a total population of 260 people. 2. Sample Size Determination Techniques Sugiyono, (2017) The sample is part of the number and characteristics possessed by the population. To determine the sample size, this study uses the Slovin formula, namely: = 1 + . 2 Information: N = Total Population n = Total Sample e = Error Margin 10% 39 N=260 People = 260 1 + (260 0.1 2) = 72.2222 = 72 People Based on these calculations, Sampling Technique The sampling technique used in this study is the Probability Sampling technique where the sample is taken using the Simple Random Sampling method which is the taking of sample members from the population that is carried out randomly without regard to the strata in the population (Sugiyono, 2017).

3.4.Data Collection Method
This study uses a questionnaire and interview techniques in using the required data Questionnaire (Questionnaire) The questionnaire method (questionnaire) is a list of questions/statements that are systematically compiled and then sent to the respondents to be filled out. The instruments for the list of questions/statements can be in the form of fields to be filled out by respondents, checklists (in the form of choices by marking in the provided column), and scales (in the form of choices by marking the column based on a certain level) (Fathoni & Hasiholan, 2013) . Before it can be used, the questionnaire must first be tested for validity and reliability. Based on the results of the questionnaire test, it can be seen whether the questionnaire is feasible and can be used to obtain data for which the results will be analyzed. According to (Sugiyono, 2017) the Likert scale is used to measure attitudes, opinions, and perceptions of a person or group of people about social phenomena.

3.5.Operational Definition
Research Variables According to Sugiyono, (2017) the operational definition is the determination of the construct or trait to be studied so that it becomes a variable that can be measured. The operational definition describes the specific method used to research and operate the construct, making it possible for other researchers to replicate the measurements in the same way or develop a better way of measuring the construct.

3.6.Data Analysis Method
Validity test Validity test is used to measure whether a questionnaire is valid or not. A questionnaire is said to be valid if the question or statement on the questionnaire is able to reveal something that will be measured by the questionnaire (I. Ghozali, 2013). According to Ghozali, (2013) measuring validity can be done by doing a correlation between the score of the questions with the total score of the construct or variable. The significance test is carried out by comparing the calculated r value with the r table for degree of freedom ( df ) = n-2, in this case n is the number of samples. So the df used is 32-2 = 30 with an alpha of 5% then it produces a table r value (two-sided test) 1) Result of r count > r table = valid 2) Result of r count < r table = invalid

If r count (each item can be seen in the corrected itemtotal correlation column) is greater than r table and the value of r is positive then the statement is declared valid.

Reliability Test
Reliability test is a tool to measure a questionnaire which is an indicator of a variable or construct. A questionnaire is said to be reliable or reliable if a person's answer to 45 statements is consistent or stable from time to time (I. Ghozali, 2013). In this test, the researcher measures the reliability of a variable by looking at the Cronbach Alpha with a significance greater than 0.60. A construct or variable is said to be reliable if it gives a Cronbach Alpha value > 0.60. 2.
Classic assumption test Before testing the hypothesis, it will first be tested for deviations from the classical assumptions

3.7.Multiple Linear Regression Analysis
In this study, the data analysis technique used is multiple linear regression. Regression analysis is basically a study of the dependence of the dependent variable (bound) with one or more independent variables (explanatory/independent variables) used to test the selected hypothesis. The equations are as follows: Y = + 1 X1 + 2 X2 + 3 X3 +e Information : Y = Purchase decision = Constant 1...β2= Regression coefficient X1 = Social Media Promotion X2 = Product Quality X3 = Price e = standard error 3.8..Test Hypothesis t test (Partial) According to Ghozali, (2013) the t statistic test basically shows how far the influence of one explanatory or independent variable individually in explaining the variation of the dependent variable. One way to do the t test is to compare the critical value of the t statistic according to the table. Meanwhile, according to Sugiyono, (2017) the t test is used to determine the contribution of each independent variable partially to the dependent variable, using the test of each independent variable's regression coefficient whether or not it has a significant effect on the dependent variable. To test whether each independent variable has a significant effect on the dependent variable partially with = 0.05. So the way to do it is: a. If (P-Value) < 0, 05 means that the independent variable partially affects the dependent variable. b. If (P-Value) > 0.05, it means that the independent variable partially does not affect the dependent variable F Test (Simultaneous) According to Sugiyono, (2017) the F test is used to determine whether the coefficients of the independent variables have a real effect or not on the dependent variable. To test whether each independent variable has a significant effect on the dependent variable together with = 0.05. So the way to do it is: 50 a. If (P-Value) < 0.05, it means that the independent variable simultaneously affects the dependent variable. b. If (P-Value) > 0.05, it means that the independent variable simultaneously does not affect the dependent variable
