Introduction
In the current era of globalization and modernization, the rapid development of communication and information technology has resulted in many changes in various aspects of life.The rapid development of technology and the emergence of new technology in a relatively close period makes the competition in the business world and marketing increasingly tight.Especially for companies engaged in communication and information technology industries.So the company strives best in delivering new technological innovations, the best quality, and everything that makes the appeal of the product and makes it different from the competitors' products.This is evidenced by the number of similar products with different brands that have its own advantages compared to other brand products.Brand becomes one of the most important things in the competition of the industrial world, especially the communication and information technology industries.Brand is one of the company's strategy to gain profit in the competition of similar product sales (Lee et al., 2010).Aaker (1991) argues that brand formation and management is not only the focus of operations for large industries, but also seen as a competitive advantage.For consumers, a brand provides product guarantees at a certain level.Walking around when shopping can spend a lot of time and effort, consumers also do not always have enough product knowledge to ensure the best purchase.In these circumstances, consumers will choose a well-known brand, although it leads to higher costs but can reduce the search effort of the product.Thus, the brand image not only affects the consumer's view of a product but also has the benefit of reducing the risk of purchase (Loudon and Bitta, 1988).
Asus which is one brand of notebooks that managed to occupy the first position of notebook sales in Indonesia.Asus itself started its business as a simple motherboard manufacturer by employing some reliable employees, now Asus has become a leading technology company in Taiwan with more than 12,500 employees worldwide.Asus has produced products in almost every category of information technology, including PC components, peripherals, notebooks, tablets, servers and smartphones.
Based on data released by International Data Corporation (IDC) in 2016, shows that sales of Asus notebooks still occupy the first position during the year 2015 with the largest number of notebook sales of 306,335 units.Then in the second position of Lenovo with the number of notebook sales during 2015 amounted to 170,100 units and the third position is occupied by Acer with the number of notebook sales during 2015 of 159,836 units (Sinaga, 2016).
Consumers typically start purchasing decisions with confirmation of needs, conduct research before purchase, and product evaluation for decision making.Product evaluation is a very important factor in decision making.Due to the ever-present risk in any purchase decision making, consumers rely on information or product cues to lower the risk of purchasing.Olson and Jacoby (1972) categorize product cues in intrinsic and extrinsic cues.First deals with product composition, including product knowledge such as design and features.Both relate to components related to the product, but not related to the product itself such as price and brand.Zeithaml (1998) suggests that intrinsic cues of product knowledge and extrinsic cues are the brand is an important factor in consideration for consumers in evaluating a product.However, there are other intrinsic product cues such as functionality and product quality that are often not obtainable directly.
Many previous studies focused on only two intrinsic and extrinsic signaling variables: product knowledge and brand image that may be effective in explaining the purchase intent of a product (Lin and Chen, 2006;Lin and Lin, 2007;Jalilvand and Samiei, 2012;Bhakar et al., 2013).However, it does not necessarily reflect the true reality.It is rare to find research that discusses how brand image, product knowledge and product quality influence buying intentions.Thus, the researcher selects three variables in intrinsic product cues (product knowledge and product quality) and extrinsic product cues (brand image) as independent variables by using price discounts as moderator variables.And do research on the influence of brand image, product knowledge and product quality to the intention of buying Asus notebook with price discount as moderation variable in Jambi City.
The research intends to explain buying intention based on consumer perception on brand image, product knowledge and quality of Asus brand notebook product and how that perception when at the same time Asus brand notebook sale given discounted price.Then interpret how the determinant of consumer perceptions can be part of corporate marketing strategy.

Literatur Review
Marketing aims to meet and satisfy the needs and desires of individuals or groups by using the exchange process.The marketing implementation of a company should be applied in the form of product planning, pricing, promotion, and distribution.In the development of marketing objectives is to create customer satisfaction by selling quality products, improving the ability of companies related to promotion, answer the challenges of competition in the business world with innovation, create long-term relationships between companies and consumers, gain profits in the development of the business world fast.
According to Kotler, P. and Keller, K. L. ( 2012) the purpose of marketing is to create satisfaction and profit for consumers with the exchange process.The satisfaction and the luck for the consumer is when the consumer gets the product in accordance with their expectations.To meet these expectations the company must sell products that have competitiveness in terms of quality and price.In the perspective of satisfying the needs and desires of consumers, then the purpose of marketing activities to inspire all the activities of a company. Brand Image Kotler, P. and Keller, K. L. ( 2012) define the brand image as a set of beliefs, ideas, and impressions that a person has for a brand, therefore the attitude and action of the consumer towards a brand is determined by the brand image.Brand image is a requirement of a strong brand.The image formed must be clear and have an advantage when compared to its competitors, when the difference and the advantages of the brand is faced with other brands.Thakor and Katsanis (1997) explain that through brand image, consumers can recognize products, evaluate quality, reduce purchasing risk, and gain experience and certain satisfaction from product differentiation.Grewal, Krishnan, Baker and Borin (1998) found that the better the brand image of a product, the greater the buying intention and recognition that consumers give for the quality of the product.To improve the brand image of a product what managers can do is to add product variety, improve product quality, offer products in a price that is more in line with the value provided, and provide additional services after purchase (Jalilvand and Samiei, 2012). Product Knowledge Peter and Olson (2010) define product knowledge as the different types of knowledge, meanings, and beliefs recorded in consumer memory.Consumers with higher knowledge will become more realistic in the selection of products that match their expectations.Where, the higher the consumer knowledge in purchasing a product, can improve the ability of consumers to make a more satisfactory choice.Brucks (1985) divides product knowledge into three types, namely: (1) subjective knowledge, level of consumer knowledge of a product; (2) objective knowledge, how much information stored in the consumer's memory relates to the brand code, attributes, use situations, the type and class of a product; (3) knowledge based on experience, how much additional information is obtained on a product after purchasing and using a product. Product Quality Kotler, P. and Keller, K. L. ( 2012) define product quality as the ability of a product to satisfy the needs expressed or implied by the overall characteristics it possesses.The quality dimensions associated with notebook products developed by Lichenstein (in Tudor and Zheng, 2014) are: (1) consumer perceptions of product quality (quality of all product attributes contained in the notebook); (2) the reliability of the product, relating to the length of battery life, physical malpractice, product age, suitability specifications, and notebook performance; (3) the level of producer innovation, consumer perceptions of producer innovation in the form of notebook design; (4) consumer perceptions of the quality of product technology, the quality of technology associated with the notebook product can be the type and model of the hardware (motherboard, processor, memory, sound card, graphics card, hard drive, battery, etc.) and software software systems and applications) used as a specification of the notebook.Tudor and Zheng (2014) found that products with better quality than similar products with other brands would increase consumers' buying intentions over the product.

 Discounted Rates
Kotler, P. and Keller, K. L. (2012) define promotion as a combination of incentives to stimulate consumers or retailers to generate direct buying reactions to products or services in the short run.Discount prices can attract consumers to try different brands, but after the promotion ends a discount the price can also lower the purchase intentions as a result of a combined discount price with lower quality.Thus, price discounts can attract consumers with economic incentives, but they can also make consumers connect lower-quality products with lower quality, which in turn will strike a profit from increased sales.

 Intention to Buy
Fishben and Ajzen (1975) define buying intentions as consumer objectives when they think of a product.According to Kotler, P. and Keller, K. L. ( 2012) consumer behavior occurs when consumers are stimulated by external factors and become a buying decision based on personal characteristics and decision-making processes.These factors include choosing products, brands, retailers, time, and quantity.In addition, the intention of buying a product arises after an evaluation process of alternatives, and in the evaluation process, one will make a series of choices about the product to be bought on the basis of brand or interest.Therefore, the intention of buying a product is influenced by their choice of a product and brand.

 Hypothesis
The research hypothesis as follows: (1) brand image has a positive and significant impact on buying intention; (2) product knowledge has a positive and significant effect on buying intention; (3) product quality has a positive and significant effect on buying intention; (4) price discounts are able to reinforce the influence of brand image on buying intent; (5) price discounts are able to strengthen the effect of product knowledge on buying intentions; (6) price discounts are able to strengthen the effect of product quality on buying intent.
