ABSTRACT This study examines the eAect of product quality and price on purchasing decisions, with purchase intention mediating variable among La Tulipe cosmetic consumers in Purworejo. Indonesia. The research addresses the growing competitiveness in the cosmetics industry, where consumers prioritize value and A quantitative method was used with 100 respondents selected through purposive sampling. Data were collected using a Likert-scale questionnaire and analyzed through multiple linear regression, t-test. F-test, and Sobel test using SPSS. The results show that price significantly influences both purchase intention and purchase decision, while product quality aAects purchase decision but not purchase intention. Purchase intention mediates the eAect of price on purchase decision, but not the eAect of product quality. These findings suggest that pricing plays a key role in shaping both interest and actual buying behavior, while product quality influences consumers more directly during the decision stage. This study oAers practical insights for local cosmetic brands in developing eAective marketing strategies that align with consumer expectations. Keywords: Product Quality. Price. Purchase Intention.

Introduction Indonesia's cosmetics industry has experienced substantial growth in recent years, driven by the country's large and predominantly young population. With over 270 million people, of whom nearly 70% are of productive age, the country presents a significant market for beauty and personal care products. This demographic advantage is complemented by an increasing awareness of health, hygiene, and personal appearance, particularly among urban youth. The widespread use of social media platforms such as Instagram. TikTok, and YouTube has further influenced beauty standards and consumer preferences, making cosmetic products a need and a lifestyle choice. Moreover, the rapid digital transformation has enabled local cosmetic brands to enter e-commerce ecosystems, expanding their market reach beyond traditional brick-and-mortar According to the Ministry of Industry, the number of cosmetic companies in Indonesia increased by 9% from 913 in 2022 to over 1,000 by mid-2023. This expansion is matched by strong export performance, with cosmetic-related products generating USD 770. 8 million in the first eleven months of 2023. These figures The Author.

Consumer behavior becomes more complex and discerning in such a highly competitive landscape. Buyers no longer rely solely on product reputation. they weigh multiple factors such as quality, price, brand trust, and user As noted by Puspita and Budiatmo . , modern consumers have developed a more rational and comparative approach to selecting products, favoring tangible value. This shift presents challenges and opportunities for local brands seeking to position themselves in a saturated market. Product quality and price are key determinants influencing consumer purchasing decisions. Product quality relates to a product's ability to meet or exceed consumer expectations, encompassing performance, durability, safety, and consistency. On the other hand, price is often the first attribute consumers notice and plays a crucial role in shaping perceptions of value and fairness. While quality ensures satisfaction postpurchase, price aAects the likelihood of initial consideration. Therefore, both variables are essential in the consumer decision-making process, individually or in interaction with other factors such as buying intention. One brand that reflects the dynamics of this market is La Tulipe, a local cosmetic manufacturer known for its dermatologically tested products tailored to Indonesia's tropical climate. Founded in 1980. La Tulipe has sustained its market presence through scientific credibility and competitive pricing. However, sustaining consumer loyalty requires a deeper understanding of what drives purchase behavior in an era of hypercompetition and shifting preferences. This study investigates how product quality and price influence consumer purchase decisions for La Tulipe products in Purworejo. Indonesia. It also explores the mediating role of purchase intention in these relationships. Understanding whether these factors directly aAect purchase decisions or operate through cognitive-aAective processes such as intention can provide marketers and local brand developers with strategic insights. By examining the relationship between product quality, price, purchase intention, and purchase decision, this research oAers empirical evidence contributing to the broader discourse on consumer behavior in the Indonesian cosmetics industry. The findings will inform targeted marketing strategies that align with evolving consumer values and expectations. II. Literature Review and Hypothesis Development Product Quality In consumer behavior, a product is a physical item and a means to fulfill consumer desires and needs. Kotler and Armstrong in Rosnaini . define a product as anything oAered to the market to attract attention, be acquired, used, or consumed to satisfy customer needs. This definition is further supported by Charty & Jr. and Yafie et al. , who emphasize that products can be tangible or intangible, provided they generate satisfaction. Rather than merely acquiring a product, consumers seek benefits, functionality, emotional satisfaction, or symbolic value. Hence, product quality becomes essential in business competition. Rosnaini . describes quality as a product's ability to perform its intended functions, including reliability, accuracy, ease of maintenance, and aesthetics. Kotler & Keller . categorize quality into performance quality . ow well the product perform. and conformance quality . ow consistent it is with predetermined Similarly. Garvin in Yafie et al. identifies eight dimensions of product quality: performance, features, reliability, conformance, durability, serviceability, aesthetics, and perceived quality. Understanding product quality from multiple dimensions helps businesses align product attributes with customer Therefore, product quality is pivotal in creating satisfaction and shaping positive purchasing Price Price is a key factor in both company profitability and consumer evaluation. Sitorus . defines price as the amount consumers must pay to obtain a product or service. Stanton in Sitorus . notes that The Author.

Website: https://goldenratio. id/index. php/grmapb/index ISSN [Onlin. : 2776-6349 price includes all financial sacrifices needed to acquire and use a product, while Kotler views it as a monetary representation of value. Consumers associate price with perceived product quality and value, especially in competitive markets. Kotler in Sitorus . suggests that price influences consumer decision-making and often becomes a reference point for perceived fairness. Aptaguna & Pitaloka . describe several key price perceptions: aAordability, fairness relative to product quality, competitiveness, and alignment with benefits. Furthermore. Sitorus . outlines three main pricing approaches: cost-based, competition-based, and optimum. The term "optimum price" refers to a price point that balances consumer willingness to pay with company profitability, while considering market demand and alternatives. Kotler & Armstrong . also highlight psychological pricing, where price influences perception beyond numeric value, and dynamic pricing, which adjusts based on time or demand. Sudirjo . expands this further by including value-based pricing and tiered pricing models to appeal to diAerent market segments. Thus, price is a cost and a strategic tool influencing consumer behavior and purchasing power. Purchase Interest Purchase interest is a consumer's conscious plan to buy a product after evaluating its value and Peter & Olson . define it as a planned behavior, while Kotler and Armstrong in Wardhana . describe it as a reflection of experience, product knowledge, and emotional response. Purchase intention is formed through cognitive and aAective evaluations, often involving brand awareness, preference, and trust. The American Marketing Association says it involves rational judgment and emotional impulse. Lucas et al. identify five key elements of purchase intention: attention, interest, desire, confidence, and SchiAman & Kanuk . and Kotler & Keller . emphasize that intention develops from a sequence of psychological responses such as awareness, preference, and conviction. Tjiptono in Aptaguna & Pitaloka . classifies it into several types: transactional, referential, preferential, and exploratory. These categories help marketers identify whether a consumer is ready to act or is still gathering information. Purchase interest is also shaped by internal and external factors, including product quality, brand image, peer influence, and situational factors like discounts or social trends (Wardhana, 2. Yamit in Ariyanti & Darmanto . highlights post-purchase satisfaction as a crucial feedback loop influencing future Buying decision The purchase decision culminates the consumer decision-making process, where choices become Kotler and Keller in Prasetiawan et al. define it as the decision to buy or not to buy a particular product, influenced by various external and internal factors. SchiAman & Kanuk . argue that this process includes evaluating product types, brands, timing, payment methods, and quantities. Firmansyah . and Alma Buchari in Maruapey et al. outline decision stages such as problem recognition, information search, evaluation of alternatives, purchase, and post-purchase behavior. These stages are influenced by consumer motivation, social context, prior experience, and perceived risk. Engel in Firmansyah . explains that internal and external stimuli trigger evaluation loops that lead to final actions. In addition, emotions play a vital role in shaping decisions, especially for products related to identity and self-expression. Thus, the purchase decision is not solely rational but is profoundly shaped by aAective responses and contextual Understanding the dynamics of buying decisions helps businesses design customer journeys that foster trust and reduce uncertainty, thereby increasing conversion rates and brand loyalty. Based on the theoretical framework and previous empirical studies, the following hypotheses are proposed to examine the relationships between product quality, price, purchase intention, and purchase decision: H1: Product quality has a significant and positive eAect on purchase intention.

H3: Product quality has a significant and positive eAect on purchase decisions. H4: Price has a significant and positive eAect on purchase decisions. H5: Purchase intention has a significant and positive eAect on purchase decision. H6: Product quality significantly aAects purchase decision through purchase intention as a mediating variable. H7: Price significantly aAects purchase decision through purchase intention as a mediating variable. Research Method Research Design This study adopts a quantitative research design using a survey approach to examine the causal relationships between variables. As Creswell . described, quantitative research involves testing objective theories by examining relationships among variables measured numerically and analyzed using statistical The survey method was chosen because it allows the collection of standardized data from a large population, making it suitable for analyzing consumer perceptions in a specific market segment. This method is particularly appropriate when studying behavioral variables such as purchase intention and decisionmaking. Research Location and Time This research was conducted in Purworejo Regency. Central Java Province. The location was selected due to its growing local cosmetic market and the region's widespread distribution of La Tulipe products. Data collection was carried out from May to July 2025. The timeframe was chosen to align with post-festival seasons when consumer purchasing behavior typically increases, providing richer data. Population and Sample This study's population includes Purworejo residents who have used La Tulipe cosmetic products. the region's total number of La Tulipe users is unknown, the population is considered indeterminate or infinite. Sugiyono, . A non-probability sampling technique, namely purposive sampling, was applied. This method was selected to ensure that respondents met specific inclusion criteria relevant to the research The criteria were: . aged 17 or older, . domiciled in Purworejo, and . having experience using La Tulipe products. This approach enhances the accuracy of responses, as the selected individuals are more likely to provide relevant insights based on actual usage experience. Using the Wibisono formula, the minimum required sample size was calculated at 96. To enhance statistical power and mitigate potential issues such as non-response, incomplete data, or outliers, the sample size was rounded up to 100 respondents. This rounding . pproximately a 4% increas. remains within an acceptable tolerance and does not negatively aAect the statistical validity of the study. Moreover, it improves data robustness and supports a more reliable generalization of results. ycsycsycsycs ycAycA = yceyce UI yuayua 2 ycAycA = . ,96 UI 0,. 2 N = 94. 05 rounded to 100 The Author.

Data Collection The primary data collection instrument was a structured questionnaire distributed directly to Each questionnaire consisted of items measured using a 5-point Likert scale ranging from Strongly Disagree . to Agree . Strongly. Direct distribution was chosen to improve response rates and reduce data entry errors, though potential selection bias is acknowledged. The questionnaire was developed by adapting validated items from previous studies relevant to product quality, price, purchase intention, and purchase decision. Data Analysis The data analysis was performed using SPSS version 16. Tests included the Kolmogorov-Smirnov test for normality, the multicollinearity test using Tolerance and VIF values, and the Glejser test for Using these diagnostic tests ensures that the assumptions for regression analysis are met, which is critical for obtaining valid results. Multiple linear regression analysis was applied to examine the direct eAects. The F-test was used to test the simultaneous influence of independent variables, while the t-test assessed the partial eAects. The Sobel test was employed to analyze the mediating role of purchase intention. This method is appropriate for examining the significance of indirect eAects in models involving mediating IV.

Therefore, all instrument items for these four variables are statistically valid. This indicates that each item accurately represents the measured construct and is suitable for data collection in this study. High instrument validity ensures that the collected data reflects the actual conditions in the field and can be reliably used for further analyses, such as reliability and hypothesis testing. Reliability Test The reliability test in this study was conducted to assess the instrument's consistency when measured under the same conditions. The technique used was the calculation of Cronbach's Alpha coeEcient, a widely accepted method for testing the internal consistency of an instrument. An instrument is considered reliable if the Cronbach's Alpha value exceeds 0. 6, which several statisticians recognize as the minimum acceptable threshold for reliability. The Author.

Price (X. with five items scored 0. Purchase Intention (Z) with five items scored 0. 709, and Purchase Decision (Y) with five items scored 0. All Cronbach's Alpha values exceeded the threshold of 0. 6, indicating that the research instruments are reliable. This means each item within the variables has good internal consistency and can be trusted for data collection. These results reinforce confidence that the instrument produces stable and accurate data suitable for further analysis to examine relationships among variables in the study. Normality Test Table 4.

Based on the normality test decision criteria, where data are considered normally distributed if the significance value is greater than 0. 05, the data in this study are statistically normally distributed. This normal distribution indicates that the data are suitable for further statistical analyses that assume normality, such as regression and correlation tests. This strengthens the validity of the analysis results and the interpretation of relationships between variables in the study. Multicollinearity Test Variable Product Quality (X. Price (X.

The results of the Glejser test show that all significance values for the tested variables are above 0. ( = 5%). According to the decision criteria, if the significance value is greater than 0. 05, it can be concluded that there is no heteroscedasticity in the regression model. In other words, the residual variance of the model is constant, and thus the assumption of homoscedasticity is fulfilled. This condition is crucial, indicating that the constructed regression model is valid and can provide eEcient and unbiased estimates. F-Test (Simultaneou.

Meanwhile, the Price variable (X. shows a regression coeEcient of 542, a t-value of 4. 375, and a significance level 0. As this value is less than 0. 05, it can be concluded that Price has a positive and significant eAect on Purchase Intention. Thus, the more aAordable or favorable the perceived price is to consumers, the higher their intention to purchase La Tulipe products. Equation 2: The Influence of Product Quality.

Finally, the Purchase Intention variable (Z) has a coeEcient of 0. 373, a t-value of 5. 509, and a significance level of 0. This also demonstrates a significant influence on the Purchase Decision. In other words, the higher the consumer's purchase intention toward La Tulipe products, the greater the likelihood that the consumer will decide to buy the product. The Author.

The Sobel test assessed the mediating role of Purchase Intention in the relationship between the independent variables and Purchase Decision. The results indicate that the indirect eAect of Price on Purchase Decision through Purchase Intention is not statistically significant, with a Sobel value of 1. 726 and a p-value 084 (> 0. This suggests that Purchase Intention does not significantly mediate the relationship between Price and Purchase Decision, implying that Price influences consumer decisions directly. Conversely, the indirect eAect of Product Quality on Purchase Decision through Purchase Intention is statistically significant, with a Sobel value of 3. 418 and a p-value of 0. 0006 (< 0. This shows that Purchase Intention eAectively mediates the relationship between perceived Product Quality and Purchase Decision. In other words, good product quality can enhance consumers' purchase intention, subsequently driving them to Discussion H1: Product Quality Has a Significant EAect on Purchase Intention The t-test result for H1 showed a significance value of 0. 071, indicating that product quality does not significantly aAect purchase intention. This finding suggests that although La Tulipe consumers recognize product quality, it is not the main factor driving their initial intention to buy. This is consistent with Mutiara . , who found similar results for MS Glow, indicating that product quality may already be perceived as a given for well-established brands. In such cases, other factors like emotional appeal, promotional messages, or peer influence may dominate the intention formation H2: Price Has a Significant EAect on Purchase Intention The statistical analysis revealed a significance value of 0. 000, indicating that price strongly and positively influences purchase intention. This confirms that consumers evaluate price not just as a cost but as an indicator of value, fairness, and accessibility. It aligns with findings by Trisdiyana & Handayani . , showing that competitive pricing stimulates interest, especially in price-sensitive It also reflects modern consumer behavior where price transparency and discount exposure, particularly via social media, aAect intention even before quality is evaluated. H3: Product Quality Has a Significant EAect on Purchase Decision The t-test showed a significance level of 0. 027, meaning product quality significantly aAects purchase This result supports the theory that while product quality may not trigger initial intention, it becomes crucial when making the actual decision. This finding aligns with Hikmah . , who noted that trusted product performance builds confidence and encourages purchase. Consumers tend to rely on previous experience and perceived reliability at the decision-making stage, making quality a core consideration when finalizing the purchase. H4: Price Has a Significant EAect on Purchase Decision The result showed a significance value of 0. 003, indicating that price positively and significantly aAects the decision to purchase. This suggests that price is not only a trigger of interest but also a persuasive factor during decision-making. The result is consistent with Az-Zahra Azis & Mukhsin . , who found that fair pricing encourages purchase across income groups. Price likely shapes The Author.

Consumers will be more likely to purchase if they feel the price is justified relative to the expected benefits. H5: Purchase Intention Has a Significant EAect on Purchase Decision The t-test result showed a significance value of 0. 000, confirming that purchase intention significantly influences purchase decision. This validates classic consumer behavior models (Kotler et al. , 2. where intention is the immediate precursor to action. The finding aligns with Trisdiyana & Handayani . , reinforcing that the likelihood of actual purchase increases significantly once intention is It also demonstrates that managing consumer attitudes and interests is crucial in moving them toward purchase. H6: Product Quality Has a Significant EAect on Purchase Decision through Purchase Intention The Sobel test result showed a p-value of 0. 084, which is greater than 0. 05, indicating that purchase intention does not significantly mediate the eAect of product quality on purchase decision. This implies that product quality's influence is more direct than passing through cognitive evaluation stages, such as intention. This could be because consumers have long been familiar with La Tulipe's product performance, reducing the need for extended consideration. This finding is similar to Mutiara . , suggesting that quality in well-known brands is a decisive driver rather than a motivator of H7: Price Has a Significant EAect on Purchase Decision through Purchase Intention The Sobel test showed a p-value of 0. 0006, indicating that purchase intention significantly mediates the relationship between price and purchase decision. This confirms that pricing influences both the aAective and cognitive stages of decision-making. It supports the micro-model of consumer response (Kotler et al. , 2. , where price perception generates attention and interest before leading to action. Thus, pricing strategies can enhance perceived value and drive the psychological momentum toward Conclusion This study aimed to examine the influence of product quality and price on purchasing decisions, directly and indirectly through purchase intention, among La Tulipe cosmetic consumers in Purworejo. Indonesia. Using a quantitative approach with 100 respondents, the study found that price significantly influences both purchase intention and purchasing decision, while product quality significantly influences purchasing decision but not purchase intention. Furthermore, purchase intention was found to mediate the relationship between price and purchasing decision, but not between product quality and purchasing These findings contribute to a deeper understanding of consumer behavior in the cosmetics industry by highlighting the asymmetric roles played by product quality and price in diAerent stages of the decisionmaking process. While price emerges as a strong predictor of intention and action, product quality primarily influences the final decision rather than the formation of purchase intention. This implies that consumers may not necessarily be drawn to a product initially because of its quality, but will heavily consider quality before completing the purchase. The role of purchase intention as a mediating variable underscores the importance of psychological processes in consumer behavior. When pricing aligns with consumer expectations of value and fairness, it fosters a positive emotional and cognitive response that increases the likelihood of actual In contrast, product quality may bypass this intention-building stage, particularly when it is already internalized as a brand attribute, as with La Tulipe. From a managerial standpoint, the findings suggest that pricing strategy should not be viewed merely as a cost-based calculation but as a strategic communication of Brands should ensure that their pricing reflects aAordability and resonates with consumer perceptions of fairness, benefit, and emotional appeal. For local cosmetic brands operating in competitive markets, aligning price positioning with perceived value is key to stimulating interest and driving action. The Author.
