Abstract

This research challenges the influence of variable costing methodology on the pricing of various flavors of "piscok" at Jl Ronggo Waluyo. The study aims to: (1) delineate the production costs of "piscok" at Jl. Ronggo Waluyo, and (2) ascertain whether the manufacturing costs are determined using variable costing. Employing a quantitative approach and non-probability sampling, the study utilizes preliminary data obtained confidentially from Small and Medium Enterprises (SMEs), garnered through interviews with SME personnel and cost data acquired during the 2023 production cycle. Upon analyzing production costs and unit pricing for "Piscok Aneka Rasa" at Jl Ronggo Waluyo using variable costs, findings reveal a per-unit production cost of Rp 448.67, with 80% attributed to labor costs. Consequently, the unit price for "piscok" stands at IDR 807.61. This comparison facilitates evaluating product pricing between conventional and variable costing methods. While the business sets the selling price for the "piscok" category at Rp1.250.000, the application of variable costing results in a significantly lower price of Rp 807.61. Thus, the price discrepancy based on these methods amounts to approximately Rp 442.38. The pricing strategy adopted by Piscok Aneka Rasa in Jl Ronggo Waluyo is notably influenced by industry standards and competitors' pricing methods. Consequently, the price set by Piscok Aneka Rasa tends to surpass the corresponding rate derived from variable costing principles.

Abstract

The primary goal of this research was to explore the impact of information, interactivity, and relevance in Instagram Reels Ads, specifically focusing on their influence on ad performance expectations within the context of FitaminCylingCulture. The study takes a quantitative approach within the positivism paradigm. The target population consists of active users of social media who are followers of the Instagram account @FitaminCylingCulture. A total of 100 respondents were selected for the study based on the Lemeshow formula with a 10% margin of error. The sampling method employed was purposive, involving the selection of active followers of FitaminCyclingCulture who are also customers. Data analysis was conducted using partial least squares (PLS), which included testing the measurement model for validity and reliability, as well as assessing the statistical significance of the hypothesized relationships through structural model testing. The majority of respondents were located in the Jabodetabek region (94.2%), with the largest age group being 20-24 years old (63.5%). It was found that these three factors had a significant positive impact on advertisement performance expectations.

Abstract

Cloud-native architectures have introduced a fundamental shift in how security and governance are applied within modern IT environments. While traditional preventive IT General Controls (ITGCs) were designed for static, centralised systems, their application in dynamic, decentralised, and automated cloud-native systems remains ambiguous and often ineffective. This study investigates the patterns of failure in preventive controls across cloud-native environments and analyses the extent to which governance frameworks fail to enforce security proactively. Employing a meta-synthetic approach, this research reviews documented cloud breach incidents from 2021 to 2024 to extract recurring failure patterns. These incidents were analysed and mapped against major security control domains, including identity and access management, configuration hardening, and observability. The findings highlight systemic gaps in the implementation of preventive measures, particularly in areas where infrastructure is governed as code, and runtime dynamics alter control effectiveness. Furthermore, the study examines how existing governance frameworks such as ISO 27001, COBIT, and NIST CSF are often too abstract or outdated to directly translate into executable policies within CI/CD pipelines and cloud-native infrastructures. The study reveals that misconfigurations, inadequate identity management, and runtime blind spots are among the most common contributors to control failures. These issues are compounded by the lack of real-time enforcement mechanisms and the misalignment between policy design and operational realities. Based on these findings, the paper proposes a shift toward Governance-as-Code and continuous control validation as critical strategies for modern preventive governance. In conclusion, the paper demonstrates that traditional ITGCs, while still conceptually relevant, require operational reengineering to remain effective in cloud-native ecosystems. A governance model that is executable, context-aware, and runtime-integrated is essential for proactive security and sustained compliance in modern digital infrastructure.

Abstract

This study investigates the influence of User Experience (UX) dimensions, integrated with the Technology Acceptance Model (TAM), on the adoption intention of Micro, Small, and Medium Enterprises (MSMEs) in the Greater Jakarta area toward the Quick Response Code Indonesian Standard (QRIS). The research examines functional qualities, which consist of Efficiency, Perspicuity, and Dependability, alongside hedonic qualities, represented by Stimulation and Novelty, as well as Trust, which serves as an essential construct in the adoption process of financial technologies. These factors were evaluated as direct predictors of adoption behaviour, while Perceived Usefulness (PU) and Perceived Ease of Use (PEOU) were employed as mediating variables to capture the mechanisms underlying the relationships, consistent with TAM’s theoretical framework. Data were collected from 400 MSMEs across various industries in the region, and analysis was conducted using Partial Least Squares–Structural Equation Modelling (PLS-SEM). The empirical results demonstrate that Efficiency strongly drives PU, emphasising the critical role of task performance and functional reliability in shaping perceptions of usefulness. Dependability and Trust significantly improve PEOU, highlighting that stable system performance and confidence in technology providers reduce complexity and foster ease of use. Interestingly, while Stimulation shows a positive and direct impact on Intention to Use, Perspicuity and Novelty yield unexpected negative effects, suggesting that overly simple or overly unfamiliar experiences may hinder rather than encourage adoption. Furthermore, PU and PEOU are shown to mediate several causal paths, reinforcing TAM’s theoretical assumptions and underscoring the value of integrating UX considerations into classical acceptance models. The final structural model exhibits strong explanatory power, with an R² of 0.903 for Intention to Use, indicating the robustness of the integrated framework and confirming the effectiveness of combining UX dimensions with TAM in explaining QRIS adoption behaviour among MSMEs.
