INTRODUCTION
The rapidly business growth causes the increased business competition.Every company competes to increase sales and create innovative marketing strategies.It aims to attract consumers.Good marketing activities should provide information for consumers about product and position the product properly in the top of consumers mind.One of the ways to improve the marketing of a product is a promotion.
The digital revolution has encouraged people to get information through various media.It also motivates people to create and develop media to facilitate access for information sharing.Social media is one of the media on the Internet that is widely used to improve the marketing of products or services.In today's digital era, people can go anywhere and anytime using social media and interact with others in the nanosecond range.Thus, the use of social media as a marketing tool is also more cost-effective and efficient.According to Wang, Chen, and Chen (2016), green cognition not only has a direct effect on purchase intention, but it also has an indirect effect on purchase intention via brand image.Some companies also use various social media for promoting its products and services.If the target market of the product is the millennial generation, the use of social media is very influential.Millennial generations grow alongside with modern technology, so the presence of social media becomes the primary medium for accessing information.Many companies are now choosing to use social media as one of the promotional media.It is because the use of cheaper and effective cost can reach all people without geographical and time constraints.Consumers can get information about the product or service easily.One of the goals of effective marketing is to introduce the existence of a product to its customers extensively and how to make the product be in the minds of consumers.
Kotler in Kertajaya (2009) stated that promotion mix was called as marketing communication mix.The company uses the strategy to communicate persuasive customer value and build customer relationships.According to Kertajaya (2009), there are five parts of the promotion mix.First, advertising is the form of ideas, products, and services promotion and presentation from sponsors.The advertising can be in the form of billboards, Internet, mailing, motion pictures, house magazines, packaging-outer displays, display signs, the point of purchase, posters and leaflets, print ads directory, broadcast ads, and packaging inserts.Second, sales, promotion is a short-term boost to buffer sales of products and services.The sales promotion can be in the form of contest, games, sweepstakes, lotteries, gifts, tie-ins, sampling, fairs and trade shows, exhibition, demonstrations, coupon, rebates, low-interest financing, entertainment, trade in allowances, and trade promotions.Third, public relation is a program designed to maintain or protect the company or the impression of the current product.The example of public relation can be press kits, speech, seminars, charity donations, sponsorships, publications, community relations, annual reports, lobbying, and media.Fourth, personal sales or personal selling is the most effective tool especially in the process of influencing the purchase, trust, and behavior of customers in delivering the product.The example of personal selling can be sales presentation, sales meeting, incentive program, and exhibition.Last, direct selling is an interactive marketing system that uses one or more advertising media to influence responses or transactions.Direct selling can be in the forms of catalogs, mail, telemarketing, Internet, and TV shopping.
According to Alma (2011), promotion is essentially a form of marketing communication.It is a marketing tool to disseminate information and improve the target market of products.The promotion can be in the form of social media.Then, one product that uses social media for promotion is L'Oréal.It is a part of PT L'Oréal Indonesia.One of the strategies to gain interest to purchase the products is by innovative and exciting promotions through social media.PT L'Oréal Indonesia uses social media such as Instagram, Twitter, Facebook, and Youtube as its promotional media.One of L'Oréal's products that is promoted through social media in February-March 2017 is L'Oréal Paris Micellar Water.The promotion of L'Oréal Paris Micellar Water uses the hashtag of #carewithmicellar.L'Oréal Paris Micellar Water is a facial cleanser with a light texture, and no alcohol and fragrance, so it is soft for the skin.L'Oréal Paris Micellar Water is formulated with innovative micellar molecules.It is capable of capturing dirt, makeup residue, and dead skin like a magnet in one swab.Meanwhile, the alcoholfree content of glycerin and its formulation take care of the natural moisture in the skin.Then, people feel fresh skin without excessive dryness.In contrast to makeup cleaning products in general, L'Oréal Paris Micellar Water can be makeup and skin care product simultaneously.
Sales promotions through social media are also attractive.L'Oréal Paris Micellar Water products consist of two variants.It has two different colors, pink for dry skin, and blue for oily skin.The creativity in promotion through social media can be seen from L'Oréal brand ambassadors, Dian Sastro and Maudy Ayunda.These two public figures represent both L'Oréal Paris Micellar Water products with #timmaudy campaign for blue L'Oréal Paris Micellar Water and #timdian for pink L'Oréal Paris Micellar Water.This promotional strategy is created to be more inherent and create interest in purchasing L'Oréal Paris Micellar Water product.Moreover, L'Oréal Paris Micellar Water product uses the discount strategy, contests, and joint promotions.According to Khatib (2016), the influence of social media differs depending on the various stages of the consumers' purchasing decision-making process.The influence is more on information post-purchase stage and is followed by purchase decision stage.The study also highlights the implications for marketers that have the opportunities to seize the influence of social media.Xu and Huang (2014) said that bonus packs had greater impact on offline impulse purchase than discounts.However, the findings were different in the online impulse purchase context.The discounts had greater impulse purchase intention than bonus packs when the product was hedonic.Bonus packs were more effective sales promotion than discounts when the product was utilitarian.In addition, discounts resulted in greater impulse purchase intention than bonus packs when the product was inexpensive.Meanwhile, bonus packs were more effective sales promotion than discounts when the product was expensive.Moreover, Khan et al. (2015) agreed there was a positive impact of word of mouth on consumer purchase intention.For L'Oréal, it already has very good awareness in the target market.However, for L'Oréal Paris Micellar Water, word of mouth strategy needs to be optimized against others product as a face cleaner water.
In this study, the author focuses on how a promotion in social media can affect consumer purchase intention.Based on the description mentioned, the authors can formulate the problem.It is whether there is relationship between promotion of L'Oréal Paris Micellar Water product in social media with purchase intention of Bina Nusantara student (Binusian) in Marketing Communication class of 2013.Thus, the research objective is to find out the relationship of promotion of L'Oréal Paris Micellar Water product in social media to the purchase intention of Binusian in Marketing Communication class of 2013.

Convenient sampling is used in the study.The sample of one hundred respondents was taken.Moreover, quantitative research software SPSS 23 is applied to test the hypothesis and interprets the results.Meanwhile, regression and correlation are done to achieve the results.The classification of respondents is based on gender and frequency of purchasing the L'Oreal Paris Micellar Water products in the last six months describes the profile of respondents based on their respective classification.It shows the gender of 100 respondents studied.In this study, the majority of respondents are female (74%), and the rest are male respondents (26%).
Purchase frequency can be seen that the majority of respondents who buy L'Oreal Paris Micellar Water in six months between 1-5 times about 57 people (57%).Then, 24 people (24%) buy the product more than 5 times, and the remaining 19 people (19%) do not buy the products in the last six months.ANOVA or F test shows the results for sales promotion variables in social media (X) to the variable of purchase intention (Y).From the ANOVA or F test, F calculates 26,028 with significance level 0,000 <0,10.It means that this regression model is feasible to be used in predicting the relationship between independent variable and its dependent variable.The result is in Table 1.R Square shows the coefficient (R2) of 0,210.It means that the variable of purchase intention (Y) can be influenced by sales promotion variables (X) about 21%.Meanwhile, the remaining 79% (100% -21%) is the contribution of other independent variables that are not included in this study.The result is in Table 2.
Where Y is purchase decision, while X is sales promotion on social media.The regression equation can be concluded; (1) the value of positive constant shows the positive influence of sales promotion variable in social media (X).(2) The constant of 12,295 states that if there is no increase in the value of the sales promotion variable (X), then the value of the purchase decision (Y) is 12,295.(3) The value of sales promotion is 0,429 states that the higher the sales promotion rate applied then increase the purchase decision by 0,429 times from L'Oréal Paris Micellar Water product.

Moreover, the second hypothesis testing criteria are as follows: Ha2: There is a positive correlation between sales promotion in social media with purchase intention.H02: There is no positive correlation between sales promotion in social media with purchase intention.
The basic second hypothesis decision making is if R is negative (-), H02 is accepted, and Ha2 is rejected.If R is positive (+), H02 is rejected, and Ha2 is accepted.R-value or correlation coefficient is 0,458.Then, the relationship of sales promotion in social media on purchase intention is positive.It means if the sales promotion increases, purchase intention also increases.Thus, H02 is rejected, and Ha2 is accepted.
The results of this study are interpreted that from 100 respondents there are 26 (26%) men and 74 (74%) women.There are 57 people (57%) with the frequency of purchasing the product between 1-5 times in six months.Then, about 24 people (24%) buy the product more than 5 times, and the remaining 19 people (19%) do not buy L'Oréal Paris products in the last six months.

In the validity test of sales promotion variables in social media and purchase intention, all items of questions are valid because r count is greater than the r table.The r table is 0,1654.Then, in the reliability test, the question items are reliable because the Cronbach alpha is greater than 0,1654 so it can be used for further study.Meanwhile, the Kolmogorov-Smirnov test shows that the significance value is 0,121.It is greater than the error rate of 0,10, so it can be concluded that the data used are normal.
In F test, it finds that there is a positive and significant influence on purchase intention of L'Oréal Paris Micellar Water.Furthermore, in simple regression test, the influence is 21%, while the remaining 79% (100% -21%) is the contribution of other independent variables that are not included in this study.The result for the first hypothesis test is that the sales promotion variable in social media has a relationship with the purchase intention.The relationship is strong enough and positive.It means if the sales promotion increases, the purchase intention also increases.
