INTRODUCTION The development of electric vehicles (EV. in Indonesia is crucial for several reasons, particularly those focused on energy security, environmental sustainability, and economic As a net oil importer since 2004. Indonesia's transition to electric vehicles is crucial to reducing dependence on fossil fuels and improving energy security (Maghfiroh. Pandyaswargo, and Onoda 2. The Indonesian government has recognized this need and has implemented policies to accelerate the adoption of battery-based EVs, which are essential for decarbonizing the transportation sector (Maghfiroh. Pandyaswargo, and Onoda 2. 3647 | P a g e https://dinastipub. org/DIJEFA Vol. No. 4, 2025 Furthermore, vehicle electrification is a strategic step to address the severe environmental challenges posed by air pollution and greenhouse gas emissions (Witjaksana et al. , 2. For example, the Balinese government prioritizes EV policies to maintain the sustainability of the tourism sector by reducing emissions and air pollution, which is crucial for preserving the natural environment that attracts tourists (Rizki et al. This initiative not only supports the local EV industry but also positions Indonesia as a key player in the regional supply chain. Furthermore. EV adoption aligns with the global trend toward clean energy and sustainable transportation, contributing to the achievement of sustainable development goals (Singh. Paul, and Pandey 2. The integration of emerging technologies such as thevehicle-to-gridfurther enhances the potential of EVs to function as dynamic energy vectors, interacting with the electricity grid and supporting renewable energy integration (Dik. Omer, and Boukhanouf 2. Collectively, these factors highlight the importance of electric vehicle development in Indonesia, encompassing energy, environmental, and economic dimensions. The role of PLN (State Electricity Compan. in providing electric vehicle infrastructure and programs is diverse, involving strategic planning, integration with the electricity grid, and the adoption of advanced technologies (Munirah et al. , 2. PLN's involvement is crucial in the deployment of static and dynamic charging infrastructure, which is essential to support the growing number of electric vehicles (EV. and their integration into the transportation and electricity networks. Charging infrastructure deployment must consider the interdependence between transportation and the electricity grid to minimize social costs and optimize network performance (Sun. Chen, and Yin 2. In the context of grid integration. PLN must address the challenges posed by increased electricity demand due to EV charging, which can impact grid stability. Smart charging strategies, such asGrid-to-Vehicle(G2V) andVehicle-to-Grid(V2G), it is crucial to manage these challenges by enabling EVs to act as flexible grid resources, providing additional services, and optimizing charging schedules to reduce peak demand and infrastructure costs (Deb. Pihlatie, and Al-Saadi 2. (Borozan. Giannelos, and Strbac 2. Promotion and pricing are crucial factors in driving electric vehicle (EV) adoption due to their influence on consumer perception and economic feasibility. The high cost of purchasing EVs remains a significant barrier, making pricing strategies and financial incentives crucial to increasing market penetration (Gerber Machado et al. Government subsidies, such as direct consumer subsidies and station subsidies, play a crucial role in reducing consumer financial burdens and addressing charging infrastructure challenges, thus driving EV adoption (Shi. Sethi, and yNakanyldrm 2. Research by Wu et al. found that consumer decisions are one of the determining factors in competitiveness. Dissatisfied consumers will likely leave the company and become customers of competitors. This will result in losses for the company. Under these circumstances, company pricing policies and intensive promotions will directly influence consumer decisions to purchase electric vehicles and indirectly impact customer satisfaction (Wu. Ock, and Su 2. Consumer behavior towards the decision to choose electric vehicles to meet their transportation needs can affect the overall performance of the company (Karampatsas et al. The level of consumer satisfaction highlighted by Fan et al. , which shows that consumer behavior in the decision to choose electric vehicle products has become a determining factor in the opportunity to win the market and sales competition for types of electric vehicle products which are now a new competitive arena in the automotive world and the intense promotion and price perception offered by companies, in addition to the existence of policies in the form of subsidies by the government (Fan. Radhakrishnan, and Zhang 2. 3648 | P a g e https://dinastipub. org/DIJEFA Vol. No. 4, 2025 The problem formulation of this research is: What is the relationship between promotion and price perception?electrifying vehicleDoes PLN influence consumers' decisions to use electric vehicles and impact consumer satisfaction? The aim of the research is to analyze promotion and price perceptions. electrifying vehiclePLN influences consumers' decisions to use electric vehicles and impacts consumer satisfaction. METHOD According to Sugiyono . , a population is a generalized area consisting of objects or subjects with certain qualities and characteristics determined by the researcher to be studied and then conclusions drawn. The population in this study was the community in the work area of PT. PLN (Perser. UP3 North Banten who had purchased electric vehicles. Because the population is not precisely known, the sample size is determined using the Lemeshow Formula. where n is the sample size. Z is the Z score at the 95% confidence level . P is the maximum estimated proportion . , and d is the sampling error rate . % or Using this formula, the sample size for the study is n = 96. OO96 respondents. In terms of promotion and price perceptionelectrifying vehiclePLN is positioned as the independent variable, consumer decisions as the intervening variable, and consumer satisfaction as the dependent variable. The following table shows the operationalization of the research variables. Based on the theoretical description and research context that has been described previously, this study was designed to test several hypotheses related to promotion and price perceptions on consumer decisions and satisfaction in using electric vehicles through the Electrifying Vehiclewhich was launched by PT. PLN (Perser. UP3 North Banten. The first hypothesis (H. states that the promotionElectrifying VehiclePLN's promotions have a positive influence on consumers' decisions to use electric vehicles. This means that the more intensive and effective the promotions, the greater the likelihood that consumers will be interested and decide to switch to electric vehicles. Next, the second hypothesis (H. focuses on price perception. It is stated that price perception towardsElectrifying VehiclePLN also has a positive influence on consumer decisions regarding electric vehicle use. In this case, if consumers perceive the price of electric vehicles offered by PLN to be affordable and commensurate with the benefits, this will encourage them to make a purchase decision. The third hypothesis (H. examines the effect of promotions on consumer satisfaction. It is expected that promotions not only attract initial interest but also provide information and experiences that contribute to increased consumer satisfaction after using the service. Furthermore, the fourth hypothesis (H. states that price perception has a positive influence on consumer satisfaction. In other words, consumers who perceive the price of electric vehicles offered as reasonable and in line with the value received are likely to be more satisfied with their decision. The fifth hypothesis (H. examines the relationship between consumers' decisions to use electric vehicles and their level of satisfaction with PLN services. In this case, an appropriate decision that aligns with consumer expectations will provide a positive experience, which ultimately impacts overall satisfaction levels. This study not only considers the direct relationship, but also considers the indirect effects of promotions and price perceptions on consumer satisfaction through the decision to use electric vehicles. The sixth hypothesis (H. states that promotions have an indirect effect on consumer satisfaction, with the decision to use electric vehicles as an intermediary variable. A similar finding applies to the seventh hypothesis (H. , where price perceptions are assumed to have an indirect effect on consumer satisfaction through the decision to use electric vehicles. To collect research data, a research questionnaire was used based on the guidelines from the variable operationalization table and distributed to 96 respondents to be filled in as the basis for data analysis. To analyze the data obtained from respondents' answers to the questionnaire 3649 | P a g e https://dinastipub. org/DIJEFA Vol. No. 4, 2025 they received, the analysis techniques used consisted of: . correlation coefficient analysis, . determination coefficient analysis, and . linear regression analysis.

All variables between the mode and median values are almost the same, so that the respondent's answer data for each variable is not far from the average Data Analysis Requirements Test Results To ensure the validity and reliability of the data used in this study, a series of prerequisite tests were conducted for data analysis. Four types of tests were conducted: validity, reliability, normality, and linearity. The results of these four tests indicated that the data obtained met the criteria required for further analysis. First, a validity test was conducted to assess the extent to which each question item in the research instrument measured the intended variable. The test results showed that all questions for the four research variables had correlation values exceeding the critical value of 0. Therefore, it can be concluded that all items in the instrument used are valid, as they have a strong and significant relationship with the constructs of the variables being measured. Second, the reliability test aims to assess the internal consistency of each item in the measurement instrument. The reliability test results showed that the Cronbach's Alpha values for all variables were above the threshold of 0. This value indicates that each item in the questionnaire provided consistent and reliable results. Therefore, all items were deemed reliable and suitable for further analysis. Next, a normality test was performed to determine whether the data distribution for each variable followed a normal distribution pattern. This test was performed by analyzing the skewness and kurtosis values for each variable. The results showed that the data had a near-normal distribution, thus fulfilling one of the important assumptions in parametric statistical analysis. Finally, a linearity test was conducted to ensure that the relationship between the independent, dependent, and intervening variables was linear. The test results showed that all combinations of relationships between variables exhibited linearity significance values below 1% . This indicates a strong linear relationship between the analyzed variables, allowing for hypothesis testing using appropriate statistical Hypothesis Testing Results The path model examining the influence of promotion and price perception on consumer decisions showed significant results and aligned with the hypothesized direction of the The data in the table shows that both independent variables positively contribute to consumer decision-making regarding electric vehicle use.

Furthermore, these two variables have been shown to positively impact consumer satisfaction levels at PT. PLN (Perser. UP3 North Banten. This study also shows that consumer decisions in choosing electric vehicles directly influence their satisfaction with PLN's services. Furthermore, promotion and price perception have also been shown to have an indirect influence on consumer satisfaction through the decision to use electric vehicles as intermediary variables. Based on these findings, the author recommends that the management of PT. PLN (Perser. UP3 North Banten increase the intensity and quality of promotions, as promotions have been proven to drive consumer decisions and satisfaction, ultimately leading to increased electricity usage (KWH). Furthermore, prices currently perceived as affordable by consumers need to be maintained to maintain public interest and satisfaction. PLN is also advised to more actively promote the use of electric vehicles as an environmentally friendly and economical alternative to fossil-fueled vehicles. Finally, with increasing public interest. PLN management needs to ensure the availability of supporting infrastructure such as charging stations in various public locations to ensure the comfort and accessibility of electric vehicle users. These efforts will strengthen PLN's position as a pioneer in the clean energy transition in Indonesia. REFERENCES
