Abstract

Startups embracing artificial intelligence (AI) as a component of their business models are quickly emerging right now. The application of AI technology in business has been going on for a while, even though recent research reveals that new or alternative business models are being implemented.It might be claimed that AI technology has been used to business models for a very long time, which puts into question the uniqueness of these business models. In order to better understand how AI companies' business models may differ from traditional IT business models, this study compares them to each other. The first step is to create a taxonomy of business models for AI businesses using a sample of 162 Worldwide Stratup, from which four archetypal business models are derived: Deep technology researcher, data analytics supplier, AI product and service provider, and facilitator of AI development The following are three main elements of startup business models for AI firms that are discussed based on this descriptive analysis: (1) new value propositions made possible by AI, (2) Various uses of data to create value and (3) How AI technology affects general business reasoning. By defining their key purposes, common instantiations, and distinguishing features, this research adds to our fundamental understanding of the AI start-up business model. This study suggests intriguing directions for further investigation in the field of entrepreneurship. À It is structured to foster entrepreneurial activity. Taxonomies and models are actually instrument.

Abstract

This research aims to evaluate the impact of SIAKAD system and information quality on user satisfaction at Esa Unggul University, Tangerang. In this digital era, higher education institutions need to optimize information technology to support academic activities. Esa Unggul University has implemented SIAKAD for various academic purposes, including online registration, taking KRS, KHS, and accessing grades. However, there are still challenges such as slow access and inaccurate information. This research applies the SUS (System Usability Scale) method to measure system usability. A quantitative approach was used by conducting a survey of student users of SIAKAD. The findings show that system quality, especially the ease of use aspect, as well as information quality, especially accuracy, have a significant influence on user satisfaction. The level of user satisfaction is reflected in the high average score and positive perceptions of students regarding the effectiveness and efficiency of SIAKAD. However, there is still room for improvement, especially in the user interface and adding features that better support academic activities. The results of this research have important implications for Esa Unggul University in its efforts to improve the quality of SIAKAD to provide more optimal services to students.

Abstract

The utilization of information technology has increased the efficiency and effectiveness of business processes, particularly in the transportation sector. To facilitate users, PT. Kereta Api Indonesia (Persero) offers ticket booking services through the KAI Access smartphone application. However, this application has received considerable negative feedback regarding its usability, which jeopardizes its effectiveness, efficiency, and user experience. The purpose of this study is to evaluate the usability of the KAI Access application and identify areas needing improvement. The data collection method used is quantitative, following ISO 9241-11 standards, and involves several users to assess the three main aspects of usability: effectiveness, efficiency, and user satisfaction. The study's findings indicate that 40% of users experience difficulties in navigating and completing tasks within the application, highlighting issues with the interface design. The average time required to complete a task is 8 minutes,longer than similar applications, indicating a low level of application efficiency. User satisfaction is reflected by an average score of 3.2 out of 5, indicating a somewhat disrupted level of satisfaction. The analysis of the study results shows that the main issues lie in unclear navigation, incomplete information, unappealing visuals,and poor application performance. To improve the usability of the KAI Access application, it is recommended to make improvements in navigation design, provide clearer and more comprehensive information, refine the visual design, and optimize the application's workflow.

Abstract

Di tengah situasi global yang semakin tidak menentu dan kebutuhan akan akses layanan kesehatan yang cepat dan andal, Halodoc muncul sebagai solusi inovatif yang memenuhi kebutuhan masyarakat Indonesia. Sebagai platform kesehatan digital terkemuka di Indonesia, Halodoc memungkinkan pengguna untuk dengan mudah berkonsultasi dengan dokter, memesan obat-obatan, dan mendapatkan layanan kesehatan lainnya secara online. Namun dari hasil pengamatan, masih terdapat beberapa ulasan negatif yang menunjukkan kekurangan dalam kepuasan pengguna terhadap aplikasi Halodoc, terutama dalam hal kegunaan. Sehingga proses evaluasi system diperlukan untuk memantau dan mengetahui sisi apa saja yang memerlukan peningkatan demi mempertahankan konsistensi kualitas platform Halodoc dalam memahami dan memenuhi kebutuhan pengguna. Pada penelitian kali ini kami menggunakan metode pertanyaan skala likert dengan memfokuskan kepada empat komponen utama yakni Learnability, Eficiency, Memorability, serta Satisfaction yang secara eksplisit diturunkan menjadi 10 butir pertanyaan menggunakan pengukuran System Usability Scale. Menurut hasil yang diperoleh, ternyata nilai rata-rata System Usability Scale (SUS) menunjukan bahwa perlunya peningkatan pengalaman pengguna, dengan tantangan terkait navigasi antarmuka dan proses transaksi tebus obat online

Abstract

Blockchain technology has gained widespread adoption across various industries due to its decentralized and transparent nature. However, its inherent characteristics, such as immutability and openness, expose the system to critical security threats and privacy concerns. This study aims to develop a comprehensive framework to enhance blockchain security and privacy, addressing prevalent challenges such as data breaches, transaction anonymity, and resistance to cyberattacks. The proposed framework integrates advanced cryptographic techniques, including Zero Knowledge Proofs (ZKP), Secure Multi Party Computation (SMPC), and enhanced encryption protocols, alongside innovative consensus mechanisms to improve system robustness. A simulation-based evaluation and a real-world case study were conducted to validate the framework. The results demonstrate significant improvements in mitigating security vulnerabilities, such as 51% attacks and double spending, while ensuring enhanced privacy through anonymized data handling and confidentiality-preserving transactions. Furthermore, the case study confirmed the framework's practicality and adaptability across diverse applications. These findings highlight the proposed framework's potential to establish a secure and privacy-preserving blockchain ecosystem, offering a solid foundation for future research and implementation in both public and private blockchain networks.
