(Hartatik. Nuvriasari, & Transportation, 2. Ms Glow is a domestic skin and facial care cosmetic product that is popular among all circles because it has beauty clinics in big cities and skincare products that are not widely spread. Ms Glow has a BPOM permit, halal certification, and has won several awards. Sales of this product reach more than 2 million per month and are in demand by various ages, making it a best-selling beauty product with a significant increase in sales. The use of celebrity endorsements has become a common strategy used by companies to increase brand trust and influence consumer purchasing decisions. Celebrities who become endorsers provide a positive image and attractiveness that can increase consumer trust in a brand or product. This tactic is very commonly used by large companies to maintain the image of their products. Several studies show that celebrity endorsements have a positive and significant influence on purchasing decisions because consumers assume that celebrities provide comprehensive and informative insight about a product. MS Glow, for example, uses several well-known celebrities in Indonesia such as Nagita Slavina. Lesti Kejora, and Sarwendah to attract consumer attention. Apart from that, the product quality and brand image built by MS Glow as a product for making glowing skin can also influence consumers' interest in trying the product. The use of celebrity endorsers has been proven to increase purchase intentions, positive attitudes towards advertising and brands. Previous research also shows that celebrity endorsement, brand image, and brand trust have a positive and significant effect on purchasing decisions for MS Glow products. According to data from the Jepara Regency Central Statistics Agency, in 2024, the population of Gen Z workers will be 161,234 people. Meanwhile, the largest employment opportunities in Jepara are in the Industrial Processing sector such as Bags. Shoes and Clothing, with a total of 271,924 people. Therefore, this number is very high in addition to the various sectors in Jepara district. (BPS, 2. Generation Z dominates the population in many cities, including Jepara, which corresponds to the target age of MS Glow product users. This makes research on the effectiveness of celebrity endorsements in generation Z very relevant. This research aims to determine the influence of celebrity endorsement, product quality and brand image on interest in purchasing MS Glow products among generation Z factory workers in Jepara Regency, with a focus on the role of brand trust as a mediating variable. Celebrity Endorsement Celebrity endorsement is a marketing strategy that uses famous public figures to promote products or services with the aim of increasing purchases of a brand. Celebrities who become endorsers can be actors, athletes, musicians, or other public figures who have attractiveness, credibility, and popularity. This public figure uses popularity to influence consumers through advertising, by expressing words to carry out brand promotions based on popularity and personality. The use of celebrity endorsements aims to attract consumer attention, increase brand awareness, build brand image, and influence purchasing decisions. Celebrity endorsement is one of the promotion methods that is the main choice in the world. The success of a product's image in the minds of consumers is determined by the company's accuracy in selecting celebrity endorsers. According to Thomson, a celebrity endorsement is an individual or group who has a lot of influence and is known by the wider community who is able to build bonds, brand personification and relationships with Therefore, the use of celebrity endorsements is considered to influence customer behavior towards a (Wahyoedi & Tj, 2. In practice, the role of celebrity endorsers in advertising can vary, such as providing testimonials about the quality or benefits of the product. Starring in product advertisements that are not related to their expertise . As well as promoting certain products or brands related to the role played in a broadcast program . Meanwhile, according to Kotler, celebrity endorsers are attractive or popular figures in advertising. The endorser should have characteristics, namely being able to maximize message delivery, having certain abilities, being known and physically attractive, being able to create a target audience. (Prabowo & Wisnalmawati, 2. The use of celebrity endorsements can provide benefits for companies, such as creating credibility, attracting attention, increasing brand recall, and building brand equity. However, there are also risks such as high costs and potential controversies involving the celebrity. Therefore, selecting the right celebrity and good relationship management is critical to the success of an endorsement strategy. Brand Trust Brand trust is the confidence that customers have in a brand's ability to fulfill its promises. This reflects the customer's perception that the brand is reliable and will deliver positive results based on the experiences and interactions they have had. This brand trust involves elements such as consistent product quality, brand integrity, transparency, commitment to values that are relevant to consumers, and the ability to fulfill expectations and promises made.

According to Chaudhuri & Holbrook, it shows that brand trust is considered as a form of customer willingness to rely on brand perceptions to achieve stated goals. Likewise, brand trust is a form of expression of trust when consumers are faced with a brand, which depends on the customer's perception that the brand will continue to be reliable and satisfying. (Falah. Indrawan, & Browo, 2. Brand trust is a consumer's willingness to trust or rely on a brand in risk situations because of the expectation that the brand will provide positive results. Brand trust creates a sense of security and reduces consumers' perception of possible risks. Brand trust is the second most important factor, after price, that influences consumers' and businesses' decisions to purchase a product. Meanwhile, according to Kotler, brand trust has a huge influence on the sustainability of a brand, because if a brand is no longer trusted by consumers, it will be difficult for products with that brand to develop in the market. On the other hand, if the brand is trusted by consumers, then products with that brand will be able to continue to develop in the market. (A. Nasution. Dalimunthe, & Syafina, 2. Building brand trust is very important because it can increase customer loyalty, create brand advocates who recommend the brand to others, and obtain repeat sales. Brand trust includes brand reliability and brand Brand reliability is based on consumers' confidence that the product can provide the promised value, while brand characteristics include the attributes and characteristics associated with the brand itself. Purchase Decision Purchase decision, or purchase decision, is a process that involves consumers in choosing between two or more available alternatives, which results in a decision to buy or not buy a product or service. Purchasing decisions are part of consumer behavior, which includes how individuals, groups and organizations select, buy, use and evaluate a product or service to satisfy their needs. This process involves combining the knowledge obtained by consumers into consideration values in choosing existing alternatives. According to Tjiptono, purchasing decisions are several methods starting from consumers recognizing a problem where consumers must be aware of a need, actively seek more information about a particular product, evaluate the product to look for alternative evaluations about how well the alternative can solve the problem, then from several stages these ultimately lead to a purchasing decision regarding what product to buy. (Ramadhan & Kurniawati, 2. Purchasing decisions involve several dimensions, including product type, brand, seller, number of products, time of purchase, and method of payment. Consumers will consider various factors such as quality, price, and product popularity before making a decision. The purchasing decision process consists of several stages, namely problem recognition, information search, alternative evaluation, purchase decision, and post-purchase behavior. Meanwhile, according to Kotler and Keller, purchase decision is an integration process used to combine knowledge to evaluate two or more alternative behaviors and choose one of them. Consumer decisions are a problem-solving approach to human activities in purchasing goods or services to fulfill their wants and needs. (Rarung. Lumanauw, & Mandagie, 2. For companies, a purchase decision is a decision-making process that involves many aspects, including supplier selection, product quality, price, delivery schedule, stock availability, and supplier reputation. Purchasing decisions influence profitability and help companies forge partnerships that align with their goals. Consumers may form preferences to make purchases based on brands that buyers like. The Influence of Celebrity Endorsements on Brand Trust Celebrity Endorsement has a positive and significant effect on Purchase Decisions. Research (Firdah.

This research uses data collection techniques by distributing questionnaires online using Google Forms to all respondents. The questionnaire in this study used a Linkert scale of 1-10. According to Sugiyono, the Likert Scale is used to measure the attitudes, opinions and perceptions of a person or group regarding social events or phenomena. (Marini. Suhanda, & Adam, 2. The total population in this study was 161,234 people. In this research, the Slovin formula is used to determine the total sample that will be used. The sample is part of the population which is the actual source of data in a study or in other words the sample must be able to represent the entire existing population (Zebua. Buulolo. Harefa, & Zai, 2. From the total population, 400 respondents were selected as samples in the Hypothesis testing uses Structural Equation Modeling (SEM) with a focus on the Partial Least Square (PLS) method and SmartPLS version 4. 0 as an analysis tool. The tests used are Outer Model Test. Inner Model Test. Mediation Test and Hypothesis Test. RESULTS AND DISCUSSION Outer Model (Measurement Mode. In this model there are two measurement models used, namely tests: Validity Test Convergent Validity in this measurement is considered sufficient when the Outer loading is above 0. 7 and the Average Variance Extract (AVE) value is at least 0.

Brand Trust and Purchase Decision variables have a value above 0. 7 in the convergent validity test, and also have an AVE value above 0. 5, so they can be considered valid. Composite Reability (C. is a measure of variable reliability that measures a reliable value of above 0. Cronbach's Alpha is a value reflecting the reliability of all indicators, with a range of values measured between zero and one. If the value is more than 0. 7 then it can be said to be reliable. (M. Nasution & Rizky, 2. Reliability Test Table 2 - Composite reliability & Cronbach's alpha values Variable Composite reliability Cronbach's alpha Celebrity Endorsement Brand Trust Purchase Decision Information Reliable Source: Data output from SmartPLS version 4. 0 (Processe. Composite reliability is done by looking at the composite reliability value of the indicator block that measures the construct. A construct is said to be reliable if its composite reliability value is > 0. Reliability testing with composite reliability can be strengthened with Cronbach's alpha. The variable assessment criteria is if the Cronbach's alpha value for each variable is > 0. (Saputra et al. , 2. In the Reliability Test, it can be shown that the indicators for all variables get a value above 0. 7 so they can be declared reliable. Inner Model (Structural Mode. The inner model is a structural model used to project causal relationships between latent variables and variables that cannot be measured directly. The inner model test or structural test aims to analyze the relationship between constructs, measure the significance of their influence, and evaluate the R-square value in the research (Susilo.

Figure 1 Ae Structural Model Bootstrapping PLS Mediation Test There are three scenarios in mediation: First, non-mediation occurs when the relationship between exogenous variables and endogenous variables is positive, while the relationship between the mediating variables is negative. Second. Full mediation occurs when the relationship between exogenous and endogenous variables is negative, while the relationship between the mediating variables is positive. Third. Partial mediation occurs when the exogenous and endogenous variables are positive, and the relationship between the mediating variables is also (Muhtarom. Cholidah. Priambodo, & Ningseh, 2. Test results using the bootstrapping method with SmartPLS 4. 0 can be interpreted based on the P value, where if the P value for indirect special effects is > 0. 05, it indicates a negative effect, while if the P value < 0. it indicates a positive effect.
