Electric vehicles can be a solution to certain social problems in Indonesia, such as pollution and an increase in consumption of energy from fossil fuels, which cannot be met by domestic production. The discussion of the TPB theoretical model, UTAUT2, and risk perception, using the structural equation modeling (SEM) method, in this study aims to provide an overview of the factors that drive interest in adopting electric vehicles in Indonesia. Data were collected from 526 respondents in various cities located in Indonesia. The results showed that the model can estimate the study variables adequately. The constructs of TPB such as attitude toward use (ATU), subjective norm (SBN), and perceived behavior control (PBC) positively affect interest in using electric vehicles. Meanwhile, ATU is influenced by performance and effort expectancies, hedonic motivation, price value, as well as functional, financial, and social risks. Another factor, known as PBC, is influenced by certain facilitating conditions. The ATU factor is the most influential on the use of electric vehicles, therefore factors such as performance expectancy, effort expectancy, hedonic motivation, price value, functional risk, financial risk, and social risk need to be properly analyzed.

Digital signatures have been widely and primarily used for document approval activities during the Coronavirus pandemic in Indonesia. This is the digital equivalent of a handwritten signature or stamped seal, although it provides more inherent security, such as validating the authenticity and integrity of a message, software, or virtual document. Therefore, this study aims to determine factors affecting consumer intention in using digital signatures based on (i) the unified theory of acceptance and use of technology 2, (ii) the theory of planned behavior, and (iii) the information acceptance model. A total of 358 respondents answered the online questionnaire containing 69 question items, with the data analyzed using the structural equation modeling technique to examine the hypotheses. The results showed that the relationship between consumers’ attitudes, perceived behavioral control, subjective norms, and information adoption had the highest and lowest effects on consumers’ behavioral intention. Moreover, the consumers’ attitudes had the most significant effect on their attitudinal intention to use digital signatures. The significant positive impact of these consumers’ attitudes had relevant implications for the sustainable adoption of the signature system. This indicated that an integrating model with the potential of extending to consumers’ intention analysis was established for digital signature adoption in other countries after the post-Coronavirus period.

Background: With the massive e-commerce transactions and document transfers, reliable system protection is needed. A digital signature is a tool that consists of encryption and decryption algorithms in a secret key to prevent data theft and online fraud. Objective: This research proposes an integrated technology-organization-environment (TOE) and the unified theory of acceptance and use of technology (UTAUT) to determine the factors affecting consumer intention to adopt the digital signature system. This research uses finance and information system departments’ perspectives in various industries. Methods: The analytical method is the Structural Equation Modeling (SEM) approach using the Smart Partial Least Square statistical version 3.0 software to examine the hypothesized connections between latent variables. Results: The results show that support from top management, size of the enterprise, and social influence have significant and positive effects on digital signature adoption. Meanwhile, user involvement and perceived simplicity have a negative effect on the adoption of a digital signature system in finance and information system departments. Conclusion: The current research suggests that executive levels in the finance and information system departments encourage the adoption of digital signature tools in doing daily tasks to increase efficiency. Keywords: Digital signature, consumer intention, finance and information system, structural equation modeling, TOE and UTAUT

Sistem tanda tangan digital telah banyak dimanfaatkan terutama untuk kegiatan persetujuan dokumen selama pandemi COVID-19 di Indonesia. Penelitian ini bertujuan untuk mengetahui faktor-faktor dari dimensi sustainability yang mempengaruhi keberlanjutan dalam menggunakan sistem tanda tangan digital berdasarkan metode pendekatan AHP. Penelitian ini menggunakan metode AHP karena metode ini mampu menyelesaikan persoalan dalam suatu kerangka berpikir yang terorganisir sehingga dapat mengambil keputusan secara efektif dan akurat terhadap suatu persoalan dalam penelitian. Hasil penelitian menunjukkan bahwa sub-kriteria continuous improvement dari dimensi ekonomi menjadi prioritas utama yang menjadi penunjang dalam keberlanjutan bisnis penyedia tanda tangan digital. Selanjutnya, melakukan analisis pemilihan platform tanda tangan digital antara PrivyID, DigiSign, dan Manual Input. Berdasarkan hasil perhitungan terhadap tiga alternatif menghasilkan platform DigiSign yang paling unggul dibandingkan dengan platform PrivyID dan Manual Input. Hasil tersebut sejalan dengan komitmen dari platform DigiSign yang memberikan kemudahan bagi pengguna agar dapat memeriksa dokumen yang tertunda dengan cepat, menandatangani dokumen dengan tingkat keamanan yang tinggi dan enkripsi berstandar Internasional, serta dapat melacak status dokumen dengan mudah. Sedangkan tanda tangan elektronik yang dilakukan dengan cara Manual Input memiliki kelemahan yang sangat kritikal, dimana tanda tangan elektronik tersebut tidak terenkripsi sehingga tidak mampu untuk melindungi dokumen dari pencurian data identitas atau entitas perusahaan oleh pihak yang tidak bertanggung jawab. Abstract             The digital signature system has been widely used, especially for document approval activities during the COVID-19 pandemic in Indonesia. This study aims to determine the factors of the sustainability dimension that affect sustainability in using a digital signature system based on the AHP approach. This study uses the AHP method because this method is able to solve problems in an organized framework so that it can take a decisions effectively and accurately on a research problem. The results of this study indicate that the sub-criteria for continuous improvement from the economic dimension is the main priority that supports the sustainability of the digital signature provider business. Furthermore, analyze the selection of digital signature platforms between PrivyID, DigiSign, and Manual Input. Based on the results of the calculation of the three alternatives, the DigiSign platform is the most superior compared to the PrivyID platform and Manual Input. This results are in line with the commitment of the DigiSign platform which makes it easy for users to quickly check pending documents, sign the documents with a high level of security and International standard encryption, and easy to tracking the document status. Meanwhile, electronic signatures made by Manual Input have a very critical weakness, where the electronic signature is not encrypted so it is unable to protect documents from theft of identity data or corporate entities by irresponsible parties.
