Website: https://goldenratio. id/index. php/grsse/index ISSN [Onlin. : 2797-5827 Based on initial observations, the prospective researcher noted several market dynamics at the Car Free Day (CFD) Boulevard in Makassar City. Some traders were observed to interact with customers using indiAerent or dismissive language, which led to an irrational and inconsistent pricing system. Product prices were often significantly higher than those in traditional markets. Furthermore, many visitors to the CFD event were not primarily there to shop, but rather to enjoy recreational activities or participate in free exercise sessions held at various points along the boulevard. Due to the uncertain number of buyers, some traders were found to diversify their product oAeringsAisuch as clothing vendors selling juice drinksAito increase their chances of making a profit.

The population for this study consists of 282 individuals, with the sample size determined using the Slovin formula at a margin of error of 0. The study will utilize quantitative data. The data analysis method used is multiple linear regression analysis. According to Sugiyono . , multiple linear regression analysis examines the functional or causal relationship between two or more independent variables (X) and the dependent variable (Y). This method is a parametric statistical analysis, and the data must meet certain conditions, including a minimum interval measurement scale and normal distribution. The study will involve several tests, including Descriptive Statistics. Data Quality Test (Research Instrumen. Classical Assumption Test, and Hypothesis Test. IV. Results and Discussion The research data was obtained through a survey method using a questionnaire, which was directly distributed to respondents at the Car Free Day (CFD) Boulevard in Makassar City. One hundred sixty-five questionnaires were distributed and subsequently collected from respondents who participated in the study. All 165 questionnaires were completed and returned, making the total number of usable samples in this study Of these respondents, 53 were male traders . %), and 112 were female traders . %). The age distribution was as follows: 25Ae30 years old . respondents or 19%), 32Ae40 years old . respondents or 37%), and 42Ae52 years old . respondents or 44%).

" The standard deviation was Regarding the Sales Volume Increase variable (Y), the minimum score was 3. 50, the maximum was 5, and the mean was 4. 4366, again indicating strong agreement among respondents. The standard deviation The validity test results show that all items for both independent and dependent variables are valid, with significance values less than 0. The reliability test results indicate that all variables are reliable, as Cronbach's Alpha () values exceed 0. For the classical assumption tests, the normality test results based on the histogram appear as a bell-shaped curve, and the Normal P-P Plot of Regression Standardized Residuals displays a pattern that aligns with the diagonal line, confirming that the data meets the normality assumption. The plot results also indicate no heteroscedasticity, demonstrating that the regression model is appropriate for predicting sales volume increases. This conclusion is supported by multiple linear regression analysis results, showing the influence of Polite Language and Good Promotion on increased sales volume. The EAect of Polite Language on Increasing Sales Volume The results of the hypothesis testing indicate that the Polite Language variable has a positive and significant eAect on increasing sales volume. This finding implies that the better the implementation of polite language, the greater the potential increase in sales volume, particularly if applied consistently and This conclusion is supported by the partial test . -tes. results, where the significance value is less 005, indicating a statistically significant relationship. The Polite Language variable in this study is measured through three indicators derived from Vygotsky's stages of language development: External Stage: This is the phase in which a child's thinking originates from external sources. It reflects how the language others use influences how individuals form thoughts and communicate. Egocentric Stage: In this phase, often referred to as adolescent egocentrism, individuals exhibit a heightened self-awareness and have diEculty distinguishing their perspective from that of others. This suggests that language is still centered around the self, with limited consideration for the listener's point of view. Internal Stage: Internalization refers to absorbing knowledge and skills into an individual's As defined by Tafsir . , internalization is the eAort or process of embedding knowledge . and skills . into an individual. This stage marks the point where language becomes fully functional in guiding thought and behavior in social contexts. These stages illustrate how polite language evolves and becomes an internalized tool that shapes individual communication and influences social interactions, including commerce. When polite language is used eAectively in sales communication, it enhances trust, improves customer experience, and increases sales All indicators of Polite Language have been implemented optimally to increase sales volume. This finding suggests that business actors or stakeholders should consistently use polite and respectful language to attract customer interest and drive sales growth. This research is supported by a study by Dewangga Jana Prasetya . , titled "The EAect of Good and Correct Use of Indonesian on Marketing Performance on Instagram. TikTok, and Facebook Social Media. The findings reveal that the proper use of Indonesian enhances closeness and resonance between a brand and its audience and has a limited direct impact on the eAectiveness of marketing communication. Although it does not significantly aAect consumer interaction, brand trust, or credibility, the research emphasizes that polite and appropriate languageAicombined with the strategic use of informal or slang expressionsAican improve engagement in social media marketing. These insights provide practical guidance for marketing practitioners regarding language usage in digital platforms to achieve their communication goals. Additionally, this study aligns with research conducted by Suprilia Marcia . , titled "The Influence of Marketing Communication on HPAI Product Sales Volume.

Collectively, these variables had a significant positive eAect on sales volume, as evidenced by an F-value of 4. reater than the F-table value of 2. with a significance level of 0. 004 (< The coeEcient of determination (RA) was 0. 162 or 16. 2%, indicating that marketing communication 2% to the variance in sales volume. In comparison, other factors outside the scope of this research influence the remaining 83. These findings collectively highlight the importance of strategic communicationAiexceptionally polite and eAective languageAiin influencing consumer behavior and increasing sales in traditional and digital marketing contexts. The EAect of Good Promotion on Increasing Sales Volume The hypothesis test results indicate that the Good Promotion variable positively and significantly aAects increasing sales volume. This implies that the better the promotion strategy implemented, the greater the potential increase in sales volume. This finding is supported by the analysis of the three leading indicators that represent the Good Promotion variable: Advertising: Advertising is defined as all forms of non-personal presentation and promotion of ideas, goods, or services by a specific sponsor that requires payment. It aims to reach a broad audience and build awareness eAectively. Sales Promotion: This refers to delivering persuasive sales messages at the most economical cost. Sales promotion eAorts target the most potential consumers by emphasizing the advantages and benefits of a product or service. Public Relations: According to Frank Jefkins . in Zainal . , public relations encompasses all planned communication activitiesAiboth internal and externalAibetween an organization and its The goal is to achieve mutual understanding and build a positive public image that supports marketing objectives. Based on the results, it can be concluded that all the indicators of Good Promotion have been implemented eAectively and have contributed positively to increasing the sales volume. This highlights the strategic importance of well-executed promotional activities in enhancing business performance. This research aligns with a study by Robby Satriawan . entitled The Influence of Promotion on Sales Volume at Kangaroo Motor Mandiri. The study results show that the Promotion variable (X) positively and significantly aAects Sales Volume (Y) at Kangaroo Motor Mandiri. This is evidenced by the t-test results, which yielded a significance value of 0. 000 < 0. The magnitude of the influence of the Promotion variable on Sales Volume is shown by a correlation coeEcient (R), indicating that the promotion variable explains 8% of the variation in sales volume. The remaining 51. 2% is influenced by other variables not examined in this study. In addition, this research also aligns with a study by Lela Elvira . entitled The EAect of Promotion on Increasing Skin Care Sales Volume at the Cantika Beauty Clinic. East Bekasi. The findings indicate that practical promotional activities within a company can significantly enhance consumer awareness. When consumers become familiar with and understand the products or services oAered, they are more likely to compare them with others in the market. If the perceived benefits are compelling, consumers make repeat purchases and even recommend the products to others. Ultimately, a well-delivered promotional message, aligned with consumer perceptions, can contribute to achieving targeted sales levels. As previously explained, the simultaneous testing (F-tes. involving both independent variablesAiPolite Language and Good PromotionAiindicates a positive and significant eAect on sales volume. This conclusion is supported by the fact that all indicators of both variables have been optimally implemented, as discussed in the partial tests. The Author.
