Introduction The development of digital technology is driving changes in consumer behavior, including in Central Java, which shows a year-on-year increasing trend in online shopping. Data from the Central Statistics Agency . recorded an increase in the number of ecommerce businesses nationally, from 2,995,986 in 2022 to 3,816,750 in 2023. Central Java itself ranked third with 674,016 e-commerce businesses, or approximately 17. 66% of the national total, underscoring the provinceAos strategic role in supporting the growth of the ecommerce sector. This increase is also in line with the increase in national e-commerce transaction value, which reached IDR 1,100. 87 trillion in 2023, indicating the increasing penetration of online shopping in peopleAos lives (BPS, 2. Furthermore. TokopediaAos 2023 report shows an increase in the number of transactions in various regions of Central Java in the first quarter of 2023 compared to the first quarter of International Journal of Economics.

Surakarta, and Magelang. This phenomenon illustrates that Central Java residents are increasingly accustomed to using digital platforms to meet their daily needs. With the support of digital infrastructure, easy marketplace access, and increasing trust in online transactions, the online shopping trend in Central Java is expected to continue to grow and provide significant opportunities for research into the factors influencing consumersAo decisions to return to online shopping. Online repurchase intention is important to research because it is a key indicator of consumer loyalty and digital business sustainability. In the context of e-commerce, repurchase intention helps companies understand the factors that drive consumers not only to make their first purchase but also to maintain repeat shopping habits. According to Bhattacherjee . in his Expectation Confirmation Theory (ECT), repeat purchases occur when consumersAo expectations regarding online services . , security, speed, and convenienc. are met or even exceeded, resulting in satisfaction that drives loyalty. Repurchase intention is key to customer retention strategies, as the cost of retaining existing customers is relatively lower than acquiring new ones (Indraswari. Mardalis, & Nugroho, 2. Therefore, researching online repurchase intention not only contributes academically to enriching the digital consumer behavior literature but also has practical implications for the sustainability of the e-commerce industry. First, digital payment technology plays a crucial role because the ease, efficiency, and practicality of payment methods will increase consumer intention to transact. According to Prayoga et al. , the transformation of digital payments in the digital economy era not only increases transaction efficiency but also encourages repeat transactions due to positive perceptions of the practicality and security of the payment system. Therefore, it can be concluded that the easier, faster, and safer the digital payment technology offered, the more likely consumers are to make repeat online purchases. Several previous studies on digital payment technology play a significant role in online shopping decisions. One study conducted by Dewi & Puspitawati . found that the use of electronic wallets . -wallet. significantly influences online purchasing decisions because it facilitates consumer transactions. Sutrisno . emphasized that the adoption of digital payments through the Technology Acceptance Model (TAM) significantly influences repurchase intentions, primarily through increased consumer trust and satisfaction . Sun. Schuckert, & Law . showed that the usability of mobile payments for hotel reservations influences repurchase intentions through attitudes, subjective norms, and PBC. they emphasized that a seamless mobile payment channel increases repurchase intentions. Second, service speed is a determinant of consumer satisfaction and the likelihood of repeat online shopping. Service speed, particularly on-time delivery, plays a crucial role in driving repeat purchase behavior because it creates expectation confirmation, that is, the consistency between service promises and actual deliveryAiwhich significantly impacts the time between purchases and consumer loyalty. In a study of expedited commerce . ltraexpedited deliver. Harter. Stich, & Spann . found that late and early-than-expected deliveries had a significant impact: deviations from the communicated time estimate affected the time interval between two consecutive orders, indicating that delivery speeds that meet or exceed expectations strengthen repurchase intentions. This is consistent with ExpectationDisconfirmation Theory, where experiences that exceed or meet expectations increase satisfaction and encourage repeat purchases. International Journal of Economics.

Issue-2, 2025 (IJEBAR) E-ISSN: 2614-1280 P-ISSN 2622-4771 https://jurnal. stie-aas. id/index. php/IJEBAR Several previous studies have examined the impact of service speed on repeat purchase LestarieAos . study showed that responsiveness and delivery speed in ecommerce services positively impact consumer purchasing decisions. Lin & Zhang . found that delivery speed is the most important dimension in logistics innovation. The shorter the time between ordering and receiving goods, the higher the likelihood of repeat purchases. Chaturvedi & Agnihotri . found that although some consumers still make repeat purchases despite delivery delays, a preference for e-tail sites that prioritize product quality, packaging, and especially delivery speed significantly drives repeat purchase intentions. Third, transaction security is crucial because it concerns the protection of personal data and consumer trust. Theoretically, the Expectation Confirmation Theory states that consumers who feel secure, and whose security meets or exceeds their expectations, will be satisfied and motivated to make repeat transactions. Therefore, strengthening security systems is not only technically important but also strategically crucial in maintaining repeat consumer purchases. Several previous studies have examined how transaction security influences online shopping decisions. Budianto & Prabowo . found that the higher the level of transaction security perceived by consumers, the greater the likelihood of repeat purchases. Indraswari. Mardalis, & Nugroho . showed that perceived security . uch as data protection through encryption and authentication mechanism. has a significant positive effect on customer satisfaction, which then mediates the relationship with repeat purchase intentions on Indonesian e-commerce platforms. Similar findings in Malaysia (Said & Saad, 2. also confirmed that site security directly influences customer satisfaction and repeat purchase intentions. Based on these conditions, the growth of the e-commerce market in Indonesia . nd its high concentration in Jav. , the adoption rate of digital payments, the role of service speed, and the importance of security and trust, this study is needed to empirically examine how Digital Payment Technology. Service Speed, and Transaction Security influence consumersAo Online Shopping Decisions in Central Java. The results of this study are expected to provide practical recommendations for e-commerce players and regional policymakers to increase consumer retention and strengthen the digital commerce ecosystem in the region.

Therefore, it can be concluded that the Digital Payment Technology variable (X. has a positive and significant effect on online repurchase decision (Y). Thus, it can be concluded that the better the implementation of digital payment technology, for example through the ease of use of digital wallets, the availability of various payment methods, as well as the speed and convenience of transactions, the greater the possibility of consumers in Central Java making repeat purchases on e-commerce These findings indicate that consumers consider the existence of a secure, fast, and easily accessible digital payment system to be a crucial factor in building online shopping The convenience of digital payments not only increases transaction efficiency but also strengthens consumer trust in e-commerce platforms, thereby encouraging loyalty in the form of repeat purchases. In other words, the Digital Payment Technology variable has a significant contribution to online consumer retention in Central Java, and this provides important input for e-commerce players to continue developing payment innovations that are responsive to user needs. Online sellers in Central Java are encouraged to continue optimizing the use of digital payment technology by offering a variety of practical, fast, and secure payment methods, such as digital wallets.

Schuckert, & Law . which shows that digital payment technology influences online repeat purchase decisions. The Influence of Service Speed (X. on the Decision Variable to Repurchase Online Shopping in Central Java The significance value obtained was 0. 000 < 0. Therefore, it can be concluded that the Service Speed variable (X. has a positive and significant effect on the online shopping decision variable (Y). The faster the service provided by online sellersAiwhether in terms of order processing, payment confirmation speed, response to consumer questions, or timely deliveryAithe greater the likelihood of consumers making repeat purchases on the same platform. Service speed in the context of e-commerce can be understood as one dimension of eservice quality. If consumers experience fast service, they will perceive the seller as having a reliable and professional operational system, thus fostering trust and satisfaction. In the context of Central Java, service speed has proven to be a strategic factor that not only enhances the transaction experience but also encourages repeat purchasing behavior. Furthermore, these findings reinforce the view that modern consumers, particularly in Central Java, with its high internet penetration and e-commerce usage, increasingly demand fast and efficient service. Consumers not only compare prices and products but also assess the overall service experience. When sellers are able to deliver speedy order processing and delivery, the psychological barrier to repeat purchases is reduced, and consumers are more likely to recommend the platform to others. In other words, service speed is a key differentiating factor in digital business competition. The results of this study are in line with research by Lestarie . Lin & Zhang . Chaturvedi & Agnihotri . which found that service speed has a significant positive influence on online repurchase decisions . The Influence of Transaction Security (X. on the Decision Variable to Shop Online Again in Central Java The significance value obtained was 0. 012 < 0. Therefore, it can be concluded that the Transaction Security variable (X. has a positive and significant effect on the online shopping decision variable (Y). The higher the level of transaction security perceived by consumers, the greater their tendency to make repeat purchases. Transaction security in the context of e-commerce includes personal data protection, payment system security, and fraud protection. Consumers will feel comfortable making transactions if the system can guarantee that their credit card information, digital wallet information, or account data are protected from unauthorized third-party access. According to Pavlou . , perceived security is a key determinant of trust in online transactions. When consumers believe a payment system is secure, trust increases, and this trust informs their decisions to make repeat transactions. In the context of Central Java, these results reflect a situation where consumers are increasingly selective in choosing online shopping platforms, considering not only price and convenience but also security. The high number of online fraud and data breaches makes security a crucial factor. Therefore, e-commerce platforms or online sellers that can provide payment systems with strong encryption, dual authentication (OTP.

Conclusion Based on the results of the analysis it can be concluded that: Digital Payment Technology (X. has a positive and significant influence on online repurchase decisions (Y) in Central Java. This means that the easier, faster, and more diverse the digital payment methods available, the higher the consumerAos tendency to make repeat purchases. Service Speed (X. has also been shown to have a positive and significant influence on online repurchase decisions. Consumers who receive fast service in order processing, payment confirmation, response to questions, and timely delivery will be more loyal and more likely to make repeat purchases. Transaction security (X. has a positive and significant influence on online repurchase Consumers feel more confident and comfortable shopping again if the digital payment system guarantees personal data protection, transaction security, and freedom from scam. Thus, it can be emphasized that the three independent variables testedAidigital payment technology, service speed, and transaction securityAihave an important contribution in driving repeat purchase decisions of e-commerce consumers in Central Java. Suggestion The following suggestions can be given based on the research results: For Seller Online sellers in Central Java need to increase their use of digital payment technology by providing easy, fast, and secure transaction options, as well as offering attractive promotions through partnerships with payment service providers. These efforts will strengthen consumer convenience and trust while building loyalty, making repeat purchases more likely. For Buyer Buyers are urged to be more careful when shopping online by choosing trusted platforms and secure payment systems. Consumers should prioritize official digital payment methods such as digital wallets. QRIS, or mobile banking with additional security features (PIN. OTP. Furthermore, buyers should carefully consider the speed of service and the sellerAos transaction security policies before deciding to shop again, to ensure a safer and more convenient shopping experience while reducing the risk of loss. For Further Research It is recommended to add other variables such as product quality, price, and user experience so that the research results are more comprehensive in explaining the factors that influence consumer repurchase decisions.
