Unified Theory of Acceptance and Use of Technology INTRODUCTION In the era of the global digital economy, e-marketplaces have become a central driver of trade system transformation worldwide, including in Indonesia. Platforms such as Tokopedia and Shopee improve transaction efficiency, expand market access, and create new opportunities for small and micro-entrepreneurs . In Indonesia, the sectorAos growth is further supported by rising internet penetration and the rapid adoption of digital devices . However, this digital transformation is unevenly distributed. West Papua, as one of IndonesiaAos easternmost provinces, continues to face substantial challenges, including high logistics costs, inadequate digital infrastructure, and low technological Recent statistics indicate that internet penetration in Papua and West Papua remains significantly below the national average, underscoring the urgency of addressing regional disparities in digital access. Under such conditions, local communities have developed adaptive, community-based approaches to remain connected to the national digital While existing studies on technology adoption are extensive, few address structural barriers, such as logistical constraints and unequal digital access, in underdeveloped regions like West Papua. One such organically emerging approach is Jasa Titip (JASTIP), which operates as an informal mechanism of digital facilitation and a collective strategy to reduce the costs of accessing e-marketplace products. JASTIP emerged as a response to the high shipping fees and logistical limitations faced by communities in West Papua. By consolidating multiple orders into a single shipment and leveraging social networks, it enables significant cost reductions. For instance, goods ordered via e-marketplaces are often delivered first to JASTIP agents in Jakarta, who then forward consolidated shipments to West Papua via cargo ships or pioneer aircraft. This arrangement distributes shipping costs among multiple buyers, making the process more affordable compared to individual deliveries. Beyond cost savings. JASTIP also fosters social support that sustains digital participation. Despite its practical significance. JASTIP has received limited academic attention, creating a notable gap in the literature on communitybased strategies for overcoming structural barriers to technology adoption. UTAUT and other digital technology adoption models emphasise user-technology interactions . These frameworks do not sufficiently account for the role of informal facilitators like JASTIP, which complement or substitute for formal infrastructure in low-access communities. To address this limitation, the present study proposes an extended UTAUT model . , incorporating JASTIP into the AuFacilitating ConditionsAy construct while adding variables such as AuPerceived Cost. Ay These extensions more accurately capture the realities of West Papuan communities, where affordability and DOI : 10. 32736/sisfokom. Copyright A2025 Submitted: August 2, 2025.

PP 557-565 interpersonal trust are critical to technology adoption. The model is ideal for studying JASTIP's adaptive, communitybased social assistance. According to Khechine et . , gender may moderate the association between community-based support and technological adoption. This perspective resonates with calls for context-sensitive revisions of UTAUT, especially for regions with limited digital accessibility. From the literature review, this study identifies three key research gaps. First, little is known about informal digital inclusion practices such as JASTIP in West Papua. Second, the UTAUT paradigm does not explicitly incorporate informal facilitators as enabling conditions. Third, no adoption model emphasizes the role of community-based social support in shaping usersAo behavioural intentions and usage of digital In addition, prior research has rarely addressed the practical barriers to adoption in low-infrastructure settings. bridge these gaps, the study integrates Perceived Cost and Perceived Trust into the model, as these constructs are particularly relevant in contexts where geographic and economic constraints complicate digital transactions . , . Previous studies confirm that cost and trust perceptions strongly influence technology adoption, especially in developing or structurally limited environments. This research also strengthens its contribution by employing ImportanceAe Performance Map Analysis (IPMA), a tool rarely applied in community-based adoption studies, to prioritize interventions and identify the most impactful factors for digital inclusion This study contributes theoretically by extending the UTAUT model through the integration of informal social facilitation within low-access communities and by introducing IPMA as a framework for prioritizing intervention strategies. Practically, the findings may assist policymakers and community leaders in designing localized digital literacy programs that recognize the role of JASTIP agents. This study addresses a significant gap in the literature and provides a more relevant viewpoint to countries facing severe structural issues than previous studies that focused on well-established digital ecosystems. II. THEORETICAL BACKGROUND Unified Theory of Acceptance Use of Technology (UTAUT) UTAUT by Venkatesh et al. supports this . The paradigm says performance expectation, effort expectancy, social influence, and enabling variables impact technology use and Hedonic incentive and perceived cost were added to UTAUT2 using digital technologies . The UTAUT framework is particularly relevant for this study as it effectively captures external factors influencing technology adoption, including community-driven practices such as JASTIP. Nevertheless, prior research has not sufficiently examined JASTIP as a distinct form of facilitating condition that supports e-marketplace adoption in low-infrastructure contexts. This study aims to address that gap by integrating JASTIP into the UTAUT framework. JASTIP as a Facilitating Conditions Jasa Titip (JASTIP) is a community-based social practice that has emerged in response to limited digital infrastructure and high logistics costs in regions such as West Papua. consolidating consumer orders into collective shipments using public transportation such as cargo ships and small regional aircraft JASTIP functions as an informal form of digital This practice enables communities to access emarketplace products at lower costs while simultaneously strengthening local social networks, which serve as a key foundation in overcoming structural barriers to technology According to the UTAUT. JASTIP is enabling conditions, or external assistance for technology usage . However, unlike formal infrastructure. JASTIP represents a non-formal and adaptive form of support, effectively substituting for digital logistics systems that are not yet widely available. Moreover, trust in JASTIP facilitators who typically come from the same social environment plays a critical role in fostering user confidence in online transactions, particularly among individuals with limited digital literacy. Thus. JASTIP serves as a contextual example of facilitating conditions within a community-based digital ecosystem. Gender Roles in Technology Gender roles have historically affected technology uptake. Men and women use digital technology for different reasons, according to many research. For example, social impact strongly influences mobile banking adoption intentions, especially among women . This implies that social recommendations might impact technology adoption, particularly among women. Gender may also modify the link between performance expectation, effort expectancy, and social impact on technology adoption intention, especially in developing nations' e-learning . They found that women prioritize social considerations and simplicity of use, whereas males prioritize technical Therefore, this study adopts gender as a moderating variable to explore how perceptions differ between men and women in using e-marketplaces, especially in the context of the presence of JASTIP as a supporting factor. Importance-Performance Map Analysis (IPMA) in UTAUT Research IPMA considers research model build importance and IPMA maps these two characteristics to assist researchers prioritize performance improvements . The Unified Theory of Acceptance and Use of Technology (UTAUT) model examines how performance expectations, effort expectations, societal effect, and enabling variables influence technology adoption using IPMA . IPMA helps researchers identify elements with a big impact but poor performance, needing more attention. The application of IPMA in the adoption strategy of emarketplaces through JASTIP provides additional insights into the key factors that need to be improved to increase user DOI : 10. 32736/sisfokom.

PP 557-565 adoption and satisfaction. For example, if performance expectations are of high importance but performance is low, then efforts should be focused on improving that aspect to encourage wider adoption. Thus. IPMA helps in formulating more effective and efficient strategies in optimizing the factors that influence e-marketplace adoption through JASTIP. RESEARCH METHODOLOGY Research Model and Hypotheses Development This research uses UTAUT to present JASTIP as a Facilitating Conditions for e-marketplace adoption. Hedonic incentive, perceived cost, and social impact drive behavioural intention and use behaviour, using gender as a moderating variable to study gender perception differences. The UTAUT implies behavioural intention promotes tech adoption . The model examines how these factors shape e-marketplace adoption via JASTIP and provides strategic insights for developing e-marketplaces in emerging regions. Fig. Research Model ) The Influence of Hedonic Motivation on Behavioural Intention and Use Behaviour. Hedonic motivation the pleasure customers get from utilizing an e-marketplace influences use and behavioural The UTAUT2 model shows that hedonic motivation greatly influences technology usage, especially in consumers . Recent studies show that people are more inclined to utilize e-marketplaces when purchasing is fun . Moreover, the enjoyment users experience not only drives current usage but also reinforces their intention to continue using the platform . These findings indicate that hedonic drive plays a significant role in promoting the adoption and continued use of e-marketplaces. Based on these insights, the following hypotheses are proposed: H1: Hedonic motivation significantly influences use behaviour in the adoption of e-marketplaces. H2: Hedonic motivation significantly influences behavioural intention in the adoption of emarketplaces. ) The Influence of Perceived Cost on Behavioural Intention and Use Behaviour. Perceived cost is a critical factor that influences both users actual behaviour and their behavioural intention when adoption an e-marketplace. High perceived costs such as shipping or transaction fees can discourage frequent us the platform . Conversely, when users perceive the associated costs as low, their intention to adopt the technology tends to increase . Therefore, perceived cost not only affects users actual engagement with emarketplaces but also shapes their continued intention to use Based on this, the following hypotheses are proposed: H3: Perceived cost significantly influences use behaviour in the adoption of e-marketplaces. H4: Perceived cost significantly influences behavioural intention in the adoption of e-marketplaces. ) The Influence of Social Influence on Behavioural Intention and Use Behaviour Social influence plays a significant role in shopping both the usage behaviour and intention of e-marketplace Social recommendations from friends, family, and the broader community have been shown to strongly affect user engagement with e-commerce platforms . Additionally, social pressure and encouragement from close social circles can further enhance technology adoption . Overall, social influence not only guides consumers decisions to use e-marketplace but also reinforces their intention to continue using them. Based on these findings, the following hypotheses are proposed: H5: Social influence significantly influences use behaviour in the adoption of e-marketplaces. H6: Social influence significantly influences behavioural intention in the adoption of e-marketplaces. ) The Influence of Facilitating Conditions on Behavioural Intention and Use Behaviour. Infrastructure and technological support significantly influence the use and purpose of e-marketplaces. Favorable conditions have been shown to enhance users engagement with technology . Moreover, the availability of resources and technical support increases users intention to adopt technology . Thus, facilitating conditions not only drive actual usage but also strengthen users intention to continue engaging with e-marketplaces. Accordingly, the following hypotheses are proposed: H7: Facilitating conditions significantly influence use behaviour in the adoption of e-marketplaces. H8: Facilitating conditions significantly influence behavioural intention in the adoption of emarketplaces. ) The Influence of Behavioural Intention on Use Behaviour. Use behaviour is strongly associated with behavioural intention, patterns of technology usage have been shown to be significantly influenced by users intention . , . The desire to continue using an e-marketplace often leads to more frequent transactions, thereby increasing actual usage. Thus, behavioural intention serves as a bridge between users motivations and their real world action in adopting emarketplaces. Therefore, the following hypotheses is DOI : 10. 32736/sisfokom.

PP 557-565 H9: Behavioural intention significantly influences use behaviour in the adoption of e-marketplaces. thereby improving the quality and generalizability of the ) Moderating Effect of Gender In studies on technology adoption, gender has been identified as a moderating variable. It has been shown that gender influences psychological traits and user behaviour . Men are generally more responsive to functional aspects such as performance expectancy, while effort expectancy. Additionally, recent studies suggest that men tend to adopt new technologies more quickly, whereas women are sensitive to perceived risk and cost . Building on these insights, this study proposes gender as a moderating variable in the context of e-marketplace adoption, particularly regarding JASTIP (Jasa Titi. Since JASTIP involves purchasing goods through intermediaries, men and women may perceive these services differently, potentially affecting their adoption decisions. Accordingly, the hypotheses are proposed: H10: Gender moderates the relationship between hedonic motivation and use behaviour in the adoption of emarketplaces. H11: Gender moderates the relationship between hedonic motivation and behavioural intention in the adoption of e-marketplaces. H12: Gender moderates the relationship between perceived cost and use behaviour in the adoption of e-marketplaces. H13: Gender moderates the relationship between perceived cost and behavioural intention in the adoption of e-marketplaces. H14: Gender moderates the relationship between social influence and use behaviour in the adoption of emarketplaces. H15: Gender moderates the relationship between social influence and behavioural intention in the adoption of e-marketplaces. H16: Gender moderates the relationship between facilitating conditions and use behaviour in the adoption of e-marketplaces. H17: Gender moderates the relationship between facilitating conditions and behavioural intention in the adoption of e-marketplaces. Data collection took place over approximately two weeks, from October 29 to November 15, 2024. The online survey link was distributed, resulting in participation from 177 respondents. The study focuses on the West Papua region, with respondent characteristics including gender, age range, and highest educational attainment. Detailed respondent profiles are presented in Table 1.

Despite falling slightly 7, the reliability of the Social Influence construct is still considered adequate, especially when supported by a Composite Reliability (CR) value exceeding 0. Indicators HM1 and BI3 were removed from the model due to their high correlations with other indicators, which resulted in Heterotrait-Monotrait Ratio (HTMT) values exceeding the recommended thresholds. Such overlaps could compromise discriminant validity, making it necessary to eliminate these indicators to ensure that each construct distinctly measures a unique concept without redundancy. This approach is in line with recommendations that consider HTMT a more accurate method for assessing discriminant validity . After establishing reflective construct reliability and convergent validity, discriminant validity was assessed. This review strives to ensure that each concept is empirically different and that the indicators accurately reflect its latent constructions without overlap. Using the Fornell-Larcker criterion, discriminant validity is assessed by comparing each construct's square root of the Average Variance Extracted (AVE) to its correlations with others. Discriminant validity is achieved when a construct's square root AVE exceeds its For exploratory and confirmatory research. HTMT should be below 0. 90 and 0. If HTMT values surpass these criteria, discriminant validity is lacking, and troublesome markers must be removed. Table 3 shows discriminant validity TABLE i. Heterotrait-Monotrait Ratio The CronbachAos Alpha (CA) value for the Social Influence variable was recorded at 0. 689, which is close to or within the acceptable threshold for reliability. In quantitative research, a CA value greater than 0. 7 is typically considered reliable, while Structural Model Evaluation Once the measurement model fulfills validity and reliability, the structural model is analyzed to examine the relationship among the research variables. This step is essential for evaluating the proposed linkages and theoretical framework. Prior to hypotheses testing, the VIF is employed to assess multicollinearity and ensure that the independent variables are not excessively correlated, a VIF value greater that 5 indicates high multicollinearity, which can distort the results of that may compromise model accuracy . therefore, only variables with VIF values between 0. 2 and 5 are retained for analysis.

This shows that social factors influence women's e-marketplace usage more. Table 6 shows that gender substantially moderates this link (T-statistic = 112. P-value = 0. P < 0. These results support previous studies showing women are more sensitive to social influence due to their greater responsiveness to social norms and environmental signals . Additionally, social support has been shown to increase womenAos likelihood of adopting new technologies . Fig. Moderating Effect of Gender To assess the structural model, the R-squared (RA) value measures how much independent factors explain variation in dependent variables. RA values of 0. 75 or more show strong predictive capacity, 0. 50 represent moderate ability, and 0. 25 or less indicate poor relevance . TABLE VII. R-Square Test Result R-square Description Moderate Moderate The study found that the R-Square (RA) value for behavioural intention is 0. 621, indicating that the independent variables explain 62. 1% of the variability, while external factors likely influence the remaining 37. According to the RA value of 0. 662, the model's independent variables account 2% of use behaviour variation, while external factors account for 33.

This analysis is instrumental in identifying factors that exhibit high importance but low performance, highlighting areas that require targeted improvement efforts. From Graph a, it is evident that facilitating conditions and perceived cost demonstrate high importance but relatively low performance in influencing behavioural intention. This finding suggests that improving service accessibility and addressing cost perceptions are critical to strengthening users' intentions. Meanwhile, in Graph b, facilitating conditions and hedonic motivation are identified as highly important yet underperforming factors in influencing use behaviour, emphasizing the need to enhance both service convenience and the quality of user experiences. Improving these aspects can foster greater comfort and sustained engagement among users in utilizing the JASTIP platform. DOI : 10. 32736/sisfokom. Copyright A2025 Submitted: August 2, 2025.

These findings are consistent with previous studies, which confirm that enjoyment and social encouragement are key determinants of usersAo intentions toward digital services . , . Users who experience excitement or entertainment while using the service are more likely to develop strong intentions to continue using it. This suggests that JASTIP serves not only as an additional service but also as a vital component fostering emotional and social engagement within the emarketplace environment.

Although these characteristics drive adoption intentions and behaviour, consumers may evaluate their quality or efficacy as poor. Thus. JASTIP platform development should emphasize user experience, infrastructure, and service features. In summary, this study confirms that hedonic motivation, social influence, and facilitating conditions are the main drivers of e-marketplace adoption, with supporting features such as JASTIP strengthening the user experience. Users who enjoy the service, have easy access, and receive social support tend to have stronger intentions to continue using the platform. DOI : 10. 32736/sisfokom.

PP 557-565 Interestingly, perceived cost does not act as a significant barrier, indicating that convenience, functional benefits, and positive experiences are prioritized over financial considerations. The relatively high RA values show that the model effectively explains variations in intention and usage behaviour in the context of platform adoption, primarily through the utilization of supplementary features such as JASTIP. Theoretical Implications The findings of this study offer several actionable strategies to accelerate e-marketplace adoption, especially in regions with limited infrastructure, such as West Papua. Given the strong influence of Facilitating Conditions (FC), local governments and service providers must prioritize improvements in digital infrastructure, ensure more stable internet access, and design user-friendly platforms with accessible technical support. Enhancing JASTIP services as intermediaries between users and e-marketplaces also presents a strategic opportunity. partnerships with e-marketplace platforms and the introduction of specialized features or loyalty incentives for JASTIP transactions could effectively reach users less familiar with digital commerce. Additionally, platforms should focus on strengthening Hedonic Motivation (HM) by creating engaging and enjoyable user experiences through interactive features, appealing interface designs, personalized product recommendations, and gamified reward systems. Marketing strategies should also leverage the importance of Social Influence (SI), particularly among female users, by utilizing local influencers, customer testimonials, and referral programs to foster trust and encourage wider adoption. Although Perceived Cost (PC) was not found to be a significant barrier, maintaining pricing transparency and offering flexible payment options can further enhance the appeal of JASTIP Discount programs or loyalty rewards could serve as additional incentives. Moreover, improving digital literacy remains essential. collaborative initiatives between governments, e-marketplaces, and JASTIP providers to conduct training and education programs on safe and efficient digital transactions will help bridge the digital divide. Lastly, the Importance-Performance Map Analysis (IPMA) results emphasize that focusing on improving Facilitating Conditions and Hedonic Motivation should be a top priority to maximize adoption and sustain the growth of e-marketplace usage in underdeveloped regions. Limitations and Future Research Directions Limitations in this study provide opportunities for further Hedonic Motivation (HM). Social Influence (SI). Facilitating Conditions (FC), and Perceived Cost (PC) are the only factors evaluated. Trust, perceived risk, and service quality were ignored. These characteristics should be included in future research to understand JASTIP service acceptance better. The research was confined to a narrow set of responders, limiting its Future studies should involve a broader and representative sample across demographic and geographic backgrounds to expand on current work. Additionally, this research examined gender as the sole Future studies might incorporate demographic factors like age, education, and technological experience into the moderation analysis. It would also be valuable to explore external factors, such as technological advancements and regulatory changes, that could affect JASTIP service adoption. By addressing these areas, future research can offer more profound and more nuanced insights, leading to more robust recommendations for enhancing the development and adoption of JASTIP. REFERENCES
