The era of globalization is a challenge and business opportunities for entrepreneurs in Indonesia both small and large scale entrepreneurs. In addition, the era of globalization makes the expansion of product markets and emerges increasingly fierce competition. Food and beverage business is one of the small-scale businesses. Currently, food and beverage business is the trend business. According to data from the Association of Food and Beverage Entrepreneurs in Indonesia/ Gabungan Pengusaha Makanan dan Minuman Indonesia (GAPMMI), it is recorded that the value of food and beverage sales reaches 700 trillion in 2012, and in 2013 increases to 800 trillion ( Industry Update, 2015 ).
Viewing the situation, the competition on food and beverage business is also getting tighter. Therefore, food and beverage business or which is commonly called the culinary business needs to increase the strength that exists in its business by giving distinctions and characteristics, in order to have its own attraction that raises the purchasing interest of the society.
Every business actor must have a goal to keep his business running, to earn profits, and to go forward. All those can be
achieved if the business actor uses a strategy that is able to compete with other business actors so that the purchasing interest of the society emerges. Competition is a form of business which is carried out in order to get a victory or to get a better position without having a physical clash or conflict.
So, to emerge purchasing interest of society on culinary business can be done by creating a good store atmosphere so that people have an interest to buy. Store Atmosphere will provide a pleasant atmosphere of purchasing environment and will provide added value to the product that is being sold. In addition, the store atmosphere also determines the image of the business itself. Because the image of a good business will ensure the survival of its business and can survive from competitors and can form loyal customers.
From the research results of Dessiana ( 2013 ) states by looking at the increasingly fierce competition conditions every business needs to improve the strength that exists in its business by raising the difference or uniqueness which is owned by the company compared with competitors in order to be able to attract consumer purchasing interest. In today's competitive business, market has concentrated on all aspects of their products from production to selling, among all other aspects, store atmosphere has been considered important as POP (point of purchase) for customers (Nugraha, 2013 ).
According to Kotler ( 1973 ) the identity of the store can be communicated to the consumer through store decoration or it is widely seen from its atmosphere. Research results from Turley and Ronald ( 2000 ) prove that the atmosphere can influence when consumers are indoors and influence them to make purchases.
This research will be conducted in District of Deli Serdang, especially in Sub-District of Percut Sei Tuan, where in it, there are many culinary business from the initial survey which is conducted by researcher about 80% of the people in this district run culinary business with very simple store concept and design.
Based on the problems that are faced by the culinary business, a better model and relevant is made to support the problems, to provide solutions, contributions, and to create excellence in an increasingly competitive competition so as to increase the purchasing interest of the society in sub-district of Percut Sei Tuan.
Levy and Weitz in ( Utami, 2010 ) who points out the 'influence of the store's state is from the character of the store's state, such as architecture, layout, marker, display, color, lighting, temperature, music and aroma, which will thoroughly create an image in the minds of consumers.
While Mowen ( 2002 ) says store atmosphere is one component of image in which there is a combination of products on sale, service, customers as a place to enjoy the pleasures of life.
In addition, the store atmosphere is also a combination of several designs that aim to stimulate purchasing interest of society on a product which is offered.
Strategy of Store Atmosphere
Store atmosphere is a strategy that involves various store attributes to attract purchasing interest of consumer. Thus the strategy which is undertaken for store atmosphere is the setting on thew aspects of the instore and outstore atmosphere at the store so that it can influence purchasing interest of consumer on products which are offered by the store.
According to Barry and Evans ( 2004 ), Store atmosphere consists of:
Exterior (Outside part of the shop)
The outside part characteristics of the store have a strong influence on purchasing interest of consumer, so it should be planned as well as possible. The combination of the outside part of the store can make it look unique, attractive, prominent and can invite people to enter the store. The outer elements of this store consist of the following sub elements:
Storefront (Front part of the shop)
Display Window (Window View)
Height and Size Building
Parking (Parking Lot)
General Interior (Inside part of the shop)
The main thing that can make a sale after the buyer is in the store is the display. The interior design of a store should be designed to maximize visual merchandising.
There are many things that will influence consumer perception on the store. According to Barry and Evans ( 2004 ), general interior elements consist of:
Color and Lighting
Scent and Sound
Width of Aisles
Room Layout (Store Layout)
Things to consider in designing layouts are as follows:
Allocation of floor space for selling, personnel, and customers.
In a store, an existing room should be allocated to:

Personnel Space (Employee Room)
The room which is provided is to meet the needs of the waitress like a place to rest or eat.
Customers Space (Customers Room)

Various kinds in determination of store traffic flow, namely:
Grid Layout (Straight Pattern)
Fixture placement in one long main hallway.
Loop/Racetrack Layout (Twist Pattern)
It consists of a main hallway that starts from the entrance, circles the entire room, and is usually circular or square, then back to the entrance.
Spine Layout (Opposite Direction Pattern)
On a spine layout, the main alley extends from front to back of the store, bringing visitors in two directions.

The simplest pattern in which fixtures and items are placed freely.
Interior Point of Interest Display (Attractive Decorating In The Store)

The Understanding of Purchasing Interest
Keller in Dwiyanti ( 2008 ) expresses interest in purchasing is how likely consumers are attached to the purchasing interest. While Kotler ( 2005 ) states interest is an effective response or process of feeling or liking a product but have not made a decision to purchase.
One way to develop purchasing interest is through promotion which is communication that informs potential buyers about income or obtains a response. According to Swasta in Kristianto ( 2009 ) consumer purchasing interests are social actions and relationships that are conducted by individual consumers, groups or organizations to assess, to obtain and to use goods through an exchange or purchase process that begins with a decision-making process that determines those actions.
The Factors that Influence Purchasing Interest
According to Bearman ( 2007 ) the growing in purchasing interest of consumer is caused by the elements that consists of:
Stimulation is a gesture that is intended to encourage or to cause a person to act.
Awareness is something that enters a person's mind. Awareness is influenced by consideration of the goods or services themselves.
Searching for information
The aspect of searching for information consists of:
Internal information is sourced from the consumer's personal in choosing goods or services that can satisfy the needs and desires.
External information is information that is obtained from outside of the consumer himself such as advertising (print media and direct seller) and social sources (family, friends, colleagues).
Ensure the distinctive nature of each option. At this step, consumers collect information which is related to the characteristics and each choice. After determining the choice then the consumer decides which items will be bought.
Alternative selection. At this step, it is done if the goods or services are a difficult choice for consumers to evaluate the available alternatives.
Purchase. At this step, consumer has made his choice and actually acts to buy goods or services by issuing a sum of money in exchange for the goods or services he obtains.
Where to buy. Place of purchase is one of consumer consideration when he is going to buy goods or services.
The Relation of Store Atmosphere with Purchasing Interest
Store atmosphere is a strategy by involving various attributes store to attract consumer purchasing interest. This opinion is supported by the opinion that says store atmosphere can influence a buyer's positive emotional state and the circumstances can cause purchases to occur. A positive emotional state will make the two dominant feelings of pleasure and arousal (Sutisna and Pawitra: 2001). Cooper ( 1981 ) who says Store atmosphere that has a beauty will form a positive image in the minds of consumers to the store, and if it lasts long then the tendency of consumers to choose the store is very high. Consumers often judge a store in its first impression from the store's atmosfere, it could be from layout, lighting, music, store colors, and room ( Schlosser, 1998 ). And this is often also the reason why a consumer has an interest or not to shop at the store. A store that has a good "personality" (in this case atmosphere) will have a higher probability of being chosen by a consumer than a bad one. This is in accordance with the theory of consumer behavior that explains about the relation between the aspects of affective and behavior in humans ( Kotler 2005 ). In the theory it is said that behavior arises as a result of affective (feeling) which is owned by consumers. Referring to the theory then if the consumer has a good affective of the product or service, there is the possibility of consumers to make purchases of these products
