Abstract

As an antithesis to the implementation of electronic voting systems based on expensive server infrastructure, this research offers a novelty in the form of pure client-side cryptography to guarantee data security in a zero-cost environment. This study evaluates the quality and acceptance of a zero-cost serverless e-voting system secured by distributed cryptography. The assessment utilized Black Box testing, ISO/IEC 25010 quality standards, and a modified Technology Acceptance Model (TAM) integrating Trust as the primary antecedent. Built on a serverless architecture (Google Apps Script), the system uses client-side AES-256 and SHA-256 encryption algorithms. A sequential explanatory mixed-methods design was applied. Quantitative data from 100 students at SMKN 7 Tangerang Regency, selected through rigorous criteria, was triangulated with qualitative IT administrator interviews. Functional testing showed a 100% success rate. The ISO/IEC 25010 evaluation categorized the system as "Highly Feasible", scoring 88.1% in Functional Suitability, 88.4% in Usability, and 87.4% in Security. PLS-SEM inferential analysis proved that perceived security significantly mediates user Trust (T-Statistics: 7.518). Interestingly, an anomaly was found where Perceived Usefulness was overwhelmingly driven by interface practicality rather than trust. This study proves that high-level data protection can be achieved without dependence on large infrastructure budgets

Abstract

This study identifies the essential components of an IT-enabled socio-technical framework to support effective remote work implementation. It draws on employees’ experiences and perceptions during the shift from office-based to remote arrangements, examining four dimensions: perceived advantages, perceived disadvantages, technological requirements, and ethical considerations in distributed work settings. Data were collected through an online questionnaire across multiple sectors, yielding 97 valid responses, predominantly from knowledge-intensive and digitally enabled organisational contexts. Qualitative thematic analysis revealed flexibility, time efficiency, and reduced commuting costs as key benefits, while communication difficulties, work–life imbalance, and technical limitations were cited as major challenges. Respondents also emphasised the importance of integrated digital tools, reliable infrastructure, and ethical guidelines related to privacy, trust, and fairness. These findings informed the proposal of six interrelated components forming a preliminary IT-enabled framework intended to support sustainable remote work practices. The anonymised dataset is openly available to encourage further research and contextual validation.
