A. Introduction
In Indonesia, many people start to have a healthy life style by having healthy activity such as exercise with the combination of healthy food whether with menu combination or adjusting their dietary habit to be healthier.Based on data from World Health organization (WHO), Indonesia ranked in top five for countries in the world with highest diabetes range (WHO, 2016).
Furthermore, according to the latest data released from WHO, 7,18% of deaths in Indonesia were caused by diabetes mellitus (worldlifeexpentancy.com, 2015).Such condition that caused by diabetes mellitus believed as the right reason for people to shift to healthy life style.In dietary habit itself, there are five types of diet that lead to healthy life style such as Mayo diet, Paleo diet, Alkaline diet, food combining, and also clean eating (Kusumangingrum, 2015).People claim that go through those dietary habit in order to lose weight and maintain the calories inside the body.
Considering the situation where people tend to shift to healthy life style, there are many business players emerge in providing healthy food with less salt and calories.3 Skinny Minnies is one of the healthy food provider based in Jakarta that provide healthy food wrapped in a diet program that helps customers to live healthy by having healthy food.In realizing their mission, 3 Skinny Minnies provides 5 days diet program with menu combination that has been set up by the chef to accommodate customer needs in having healthy foods.
Nowadays, social media already recognized as one of the most powerful marketing tools, with wider outreach and considerably low cost (sexsmith & Angel, 2012).Latest survey by jajak pendapat app (blog.jakpat.net)about Indonesia social media trend Q1 2017 shows that Facebook is in number one as the most social media used by people followed by Instagram, Path, Twitter and Linkedin.However, Instagram is the most preferred social media for shopping purpose (blog.jakpat.net).
3 Skinny Minnies utilizes online channel as their sales channel which are Instagram and Website.
In Instagram, 3 Skinny Minnies fill the content with product picture, promotion and also celebrity endorsement such as Dian Sastro Wardoyo who known as Indonesian actress who has more than 5 million followers of her Instagram account (@therealdisastr) and promoting healthy lifestyle as well by endorsing healthy based product and also become brand ambassador of several consumer goods product.In the website, 3 Skinny Minnies more focus on detail information about their product and offer as well as price information of their package.Since 3 Skinny Minnies utilizes Instagram as their main channel to interact with customer and potential customers with aspiration that target customers attracted to visit their website and purchase 3 Skinny Minnies products.However, it is not an easy task to make Instagram as an effective channel since the account should also obtain many followers that ought to be their potential target customers, that is why 3 Skinny Minnies utilizes Dian Sastro Wardoyo as endorser of their product in order to attract target customer considering frequent activity of the endorser in the Instagram and number of followers that the endorser has as well as image that the endorser posses in the eye of society.
Based on the current situation, This research aims to study and analyze the influence of existing 3 Skinny Minnies celebrity endorsement in driving customer's purchase intention towards the product that offered.In order to make the research more focus and directive, three aspects will be evaluated regarding celebrity endorsement such as; the source of credibility, the source of attractiveness model, and product congruency as stated by previous research (Ohanian, 1990;Shin, 2010;Mngan, 2013;Jatto, 2014).

Celebrity Endorsement
Celebrity endorsement is one of the strategies that commonly used by business player as one of the promotional tools.McCracken stated that celebrity endorser in terms of public figure whose well known and recognized in the eye of public often utilized by business player to boost up business reputation.There are several forms of endorsement that commonly practiced which are giving expert opinions, become a spokesperson for certain product, or even only associated to with a product (McCracken 1987;Seno and Lukas, 2007).Utilization of celebrity as endorser will increase customer brand awareness, grab customer attention, as well as make the advertisement memorable which improving brand recall (Ahmad & Rafique, n.d).There are certain parameters that determine compatibility between brand image and celebrity such as popularity, physical attractiveness, credibility, prior endorsements, celebrity user status towards the brand, profession, celebrity's fit with brand image, target audience of celebrity, celebrity associated value, acquisition cost, product match, and controversy risk.

Source of Credibility and Attractiveness Model
Source of credibility is a term that used to indicate point out positive characteristic by the communicators that will influence message acceptance and receiver's trust (Kutthakaphan, 2013).
Credibility is important matters for celebrity since celebrity perceived as credible source of information (Goldsmith et al, 2000;Hoekman, n.d).In order to measure effectiveness of celebrity endorsement, Hovland et.al. developed a source credibility model and attractiveness model in 1953.The measurement consist of expertise and trustworthiness, and also the attractiveness model which emphasizes on the character of attractiveness which nowadays still utilized by the researchers (Cheung et. al., 2009;Methaq, 2011;Umeogu, 2012;McCroskey, 2015).Ohanian supported source of credibility model and attractiveness model in 1990 on her research and developed deliberation source of credibility model with multi dimensional explanatory model by developed a scale that consist of three components which are, trustworthiness, expertise and attractiveness.Many recent studies utilize the three dimension of Ohanian to measure effectiveness of celebrity endorsement (Lord & Putrevu, 2009;Spry et al.., 2011;Hussain et al., 2012;Wei & Lu, 2013;Muda, Musa, Mohamed, & Borhan, 2014).There are 15 points that constructed as the reliable and consistent measurement scale to the source of credibility model by Ohanian.Also, the realibility and validity of those components have been tested with a large pool of item and therefore those 15 semantic differential scale is determined as qualified for future research (Kutthakaphan & Chokesamritpol, 2013).Those 15 points were set up by evaluating three main aspects which are, Trustworthiness, expertise, and attractiveness.
Trustworthiness refers to honest, integrity and believability of the endorsers and those believed in supporting the influence process to the customers ' belief, opinion, attitude, as well as purchasing behavior (Ohanian 1991;Edrogan et al., 2001;Oyeniyi, 2014).Ahmed (2014) used Ohanian's 15 point source of credibility model scale as a tool to measure the level of trustworthiness of celebrity endorser in his research.There are 5 points of sub categories from Ohanian's trustworthiness which are dependable, reliable, honest, sincere, and trustworthy.Expertise defined as the extent to which a communicator is perceived to be source of valid requirement of the object or issue (Muda et al., 2015).
Aaker and Meyers argued that customers are more convinced to purchase a product the endorsed by well informed celebrity or whose profession is related to the brand function.Also, the level of persuasiveness by celebrity is likely enhanced by the expertise that possessed by those celebrity (Oyeniyi, 2014).Therefore, through Ohanian's 15 point source credibility model scale, expertise measured by 5 sub category in semantic scale which are, expert, experienced, knowledgeable, qualified and skilled.Erdogan stated that the concept of attractiveness acquired by several items such as intellectual skills, personality attraction, life styles, physical performances, and skills of endorsers (Adani, 2015).McGuire also developed the source of attractiveness model that depends on three important dimensions such as similarity, likeability, and familiarity in his research on 1985 and still used by researchers nowadays (Braunstein, 2006;Atay, 2011;Peetz, 2012;Hugosson, 2014;Fang, 2015).Previous study by Clow, James et al., (2006) has shown that the attractiveness may develop a positive attitude toward purchase intention which supported by visual advertisement.Ohanian found that attractiveness can positively influence the customers behavior toward products and services rather than those which endorsed by unattractive figure (Hasan & Jamil, 2014).
Therefore, celebrity attractiveness perceived to posses positive influence on products or services that they represent.Thus, Ohanian specified attractiveness dimensions through 15 point source of credibility model scale and measured by 5 sub categories in semantic scale such as, attractive, classy, beautiful, elegant and sexy.

Celebrity and Product Congruent
Persuasiveness of celebrity endorsement defined by Kahle and Homer as a function of how well the endorser's image fits with the product's image or can be simplified that celebrity endorsement is persuasive enough when the endorser has a certain fit with product that he or she represents in terms of image and better known as "match up hypothesis" (Nung et al. 2011).Through this concept, there should be a match and congruency between the image of celebrity endorser with brand and product in order to generate effective advertising through celebrity endorser.Thus, there are two schemas of congruity and in congruity that considered in this matter.
In previous research by Mandlers (1989), based on previous information that have been received in customers' memory, customers expectations can be identified by the schema congruity as the level of new information that spread to the customers.Meanwhile, Meyers & Tybot's study on 1989 stated that schema of congruity established when there is a relevance among the endorser's image and product's image in the eye of customers, which can be built through the congruity between endorser and product.Thus, Positive responses can be created because there is a match between advertisement with customers' expectation and help customers to predict future outcomes of product (Nung et al., 2011).
In the other hand, Desai & Gentruck (1995) as cited in Nung et al., (2011) defined that any information which is not reliable with the previous expectation by the customers as schema incongruity.Because of that, schema incongruity happens when the image of celebrity does not match with product image, then more efforts would needed to resolve the incongruity.Therefore, previous researches that have been done by Kamins & Gupta (1994) (2008) found that the desired level of believability and effectiveness is a result of highest congruity between the image of product and the brand compared to the lowest congruity.

Meaning of Transfer Model
Developed by McCracken (1989) the meaning of transfer model theory defined the celebrity endorsement process as a process of a meaning transfer.In this model, figure properties that possessed by the endorser should be able to be transferred to a specific product or brand that they represent, and later from the product to the customers (Löfgren & Li, 2010).The transfer process involves celebrity, product and customers that divided into three stages which are meaning transfer process, Carrying Process, and disseminating process.
First stage, celebrity is expected to be able to deliver a meaning in depth and clever way to strengthen the product by taking the advantage of endorser popularity in the advertisement (Kutthakaphan & Chokesamritpol, 2013).Cultural meanings that carried by the endorser in the endorsement process can determine the effectiveness of endorsement (Nhung et al., 2011).
Several meanings that represent the endorsers are character, status, class, lifestyle, and charm that brought from their career path as well as society.
Second stage, when celebrity carry their meanings and image to the advertisement and transfer it to the product that they represent in order to develop image of product as well as the brand (Nhung et al., 2011).Business player need to choose celebrity endorser who able to represent product characteristics precisely and the advertisement message should also have similar characteristic between the celebrity endorser and the product (Kutthakaphan & Chokesamritpol, 2013).Therefore, celebrity endorser and the product must have a connection in order to create high similarity that support carrying process.This condition where there are similarities between endorser and the product will create an assurance for the customer towards product and brand that represented by celebrity endorser (Löfgren & Li, 2010).
Third and last stage, disseminating process that is claimed as the most difficult and high level of complexity compared to two previous stages (Nhung et al., 2011).In this stage, celebrity endorsement should be able to makes the properties of a product become the properties of the customers since they try to find the product with practical meanings as they put efforts on searching the meanings that they need.Product meaning cannot enter the customer's mind instantly.Towards the third stage of process, synergy between celebrity endorser and the product should be able to claim, interchange, care for, and use the customer good in order to posses the meaning (Löfgren & Li, 2010).McCracken stated that celebrities have a crucial role in the final stage of meaning transfer since identity of the brand is created through the endorsement as well (Kutthakaphan & Chokesamritpol, 2013).Thus, when customers have possessed the meaning, it couild be said that the last part of the process is accomplished (Belch & Belch, 2009).

Customer Attitude
Attitude is a form of response that comes from human as they react to certain condition, which in extent will create cognitive, affective, and behavior as it stated by Rosenberg & Hovland (Kutthakaphan & Chokesamritpol 2013).Furthermore, attitude is a combination and integration of three components affect, cognition, and behavior system, which influence each other so that the entire attitude can change if there is a change in one of the component.Therefore, multi component models of attitude were developed into two dimensions, stated by Rosenberg & Hovland (1960).First dimension is stimuli, which is categorized as independent variable, which is able to influence customers' attitude by a certain event that happen in the environment.Second is an intervening variable of attitude, which are affective, cognition, and behavior (Kutthakaphan & Chokesamritpol, 2013).Affective include feelings in representing sensation, emotion, and impressions.Cognition is essentially consists of learning, thinking, remembering and the likeliness (Kutthakaphan & Chokesamritpol, 2013).Behavior essentially consists of action, activities, and habits.Therefore, if the business player understands customer's attitude, it will help developing the best method to make the product more preferable in terms of customer's perspective by influencing their attitude and change the behavior.
Existence of a brand is created when there is a form of identification towards all the marketing entity such as such a product, an outlet, a service, or even a geographical place for example entire country, region, state or city obtains its own name, term, sign, symbol, design, or other specific combination of these elements (Shimp, 2010).However, there will always be a choice for customers to select appropriate product and service based on their needs even in a limited time to make a decision.The well-known and trusted brand are be able to simplify their decision making process by having effective advertisement that inspire customers to select the brand.From customer point of view, brand is such a promise, as they will purchase from well-known and trusted brand (Belch & Belch, 2003).Driven by this situation, business player should be able to generate strong brand proposition of their products.All of the marketing activities and tools should provide uniformed message in order to prevent and avoid misinterpretation of the message that delivered to the customers.Brand should also be able to create gimmick as differentiator from another brand.Such interaction that made by brand and customers may lead to certain attitude toward the brand through customers' perspective, which determined by its provided quality and satisfaction (Doss, 2011;Keller, 2013).Since the judgment could be positive or negative, business player should be able to make consistent product's quality in line with its claim in the advertisement.

Purchase Intention
Purchase intention defined as that made by customers in deciding to purchase a certain brand or product (Shah et al, 2011).There are several elements that include in purchase intention such as customer's willingness to consider in buying the product, buying intention of the product in the future and repurchase decision (Rahman et al., 2012).Also, there are several stages that involve in consumer buying decision process to purchase and repurchase certain product.Consumer buying decision process explained into five processes, which are need recognition, information search, evaluation of alternatives, purchase decision, and also post purchase decision (Belch & Belch 2003;Kotler & Armstrong, 2010).Customers will through all process before they decide to purchase certain product or to repurchase a certain product.

The Relationship between Celebrity Endorsement and Attitude toward the Brand
Based on previous researches, it is proven that product that endorsed by well known and attractive celebrity attracts more and tend to catch more awareness from the customers compare to unknown endorser who does not posses any specialty or character.Celebrity endorsement program will influence the attitude toward the brand significantly due to image that formed to the product by celebrity endorser (Ohanian, 1990;Erdogan, 2001;Amos et al., 2008;Hasan & Jamil., 2014).Choi & Rifon (2012) also supported several previous researches that significant influence on customers' toward the brand compared to attractiveness is a result of congruence of the image between the celebrity endorser and the product that they represent.Furthermore, credibility of the endorser positively affect the attitude toward the brand compared to the attractiveness (Muda et al., 2014).Based on their research, it is found that congruence between celebrity and the product image that being endorsed, well product knowledge, and capable in delivering the meaning of the product to customers in increasing believability of endorser credibility.

The Relationship between Celebrity Endorsement and Purchase Intention
Customers' perspective regarding source of information of the product or service is essential in leading potential customer to make a purchase plan in the future.In this case, it is important to deliver same message that can be interpreted easily to the customer's mind by both endorser and the product, since the cognitive process works behind (Hasan, & Jamil, 2014).Celebrity endorser carries certain attribute to develop the customer's buying behavior.Thus, positive attitude of the customer toward celebrity endorser will increase buying intention to the product that being endorsed (Amos et al., 2008).

The Relationship between Attitude toward the Brand and Purchase Intention
Some previous studies found that attitude toward the brand has positive and significant influence on customer purchase intention (Wahid & Ahmed, 2008;Choi & Rifon, 2012;Muda et al., 2014).
Meanwhile, in order to increase brand awareness and create emotional connection of potential customers to support customer purchase decision, advertisement is one of the attempts that can be executed by business player (Latif & Abideen, 2011;Mirabi et al., 2015).Feeling that developed between brand and customer in terms of pleasant impression toward the brand will develop desired attitude toward the product (Mirabi et al., 2015).Therefore, researchers intend to investigate and evaluate relationship between attitude toward and purchase intention due to support from previous researchers.
