Abstract

The rapid development of e-commerce has generated huge volumes of data, opening up opportunities to analyze product demand patterns more accurately. This research aims to develop a product demand prediction model based on big data analysis. The data used includes sales transactions, product searches, customer reviews, and external factors such as seasons and promotions. The main methods used are machine learning techniques such as random forest regression and neural networks to build predictive models, with data extraction, transformation, and analysis processes carried out using big data platforms such as Hadoop and Spark. The resulting model is evaluated using accuracy metrics, such as mean absolute error (MAE) and root mean square error (RMSE), to measure prediction performance. The results show that the use of big data in product demand prediction can increase the accuracy of inventory planning and stock management by up to 25% compared to conventional methods. These findings make a significant contribution to the optimization of e-commerce operations, especially in more efficient and timely data-driven decision-making.

Abstract

Blockchain is a modern technology with the capability to create a high level of transparency in data processing. Due to this capability, blockchain has begun to evolve across various sectors, one of which is the healthcare sector. This literature review examines the implementation of blockchain in healthcare systems, focusing on security management in electronic medical records (EMR) and clinical trial data management. A total of 20 journals published between 2019 and 2024 were reviewed, sourced from Google Scholar. The objective of this literature review is to gather information and data based on parameters determined by the researchers. The findings indicate that the utilization of blockchain for data security in the healthcare sector is predominantly applied to Electronic Medical Records (EMR). Furthermore, despite blockchain's significant potential across various fields, particularly in healthcare, this literature review also highlights several limitations of blockchain technology. The conclusion of this study suggests that with further innovation, blockchain can play a crucial role in enhancing security within digital healthcare, making it safer and more efficient.

Abstract

Blockchain technology has emerged as a significant innovation across various business sectors, offering transparency, security, and operational efficiency. Blockchain is divided into two main categories public and private each with its own advantages and challenges. Public blockchains, such as Bitcoin and Ethereum, enable full decentralization, enhance transparency, and reduce the need for intermediaries. However, they often face scalability issues and high transaction costs. In contrast, private blockchains offer greater control over data and network access, making them more suitable for enterprises that require efficiency and regulatory compliance, though they come with a higher risk of centralization. This study employs the Systematic Literature Review (SLR) method to analyze and compare both types of blockchain in a business context. By reviewing 20 relevant scholarly publications, this research identifies key factors influencing blockchain adoption, including technological readiness, regulatory frameworks, and stakeholder awareness. The findings indicate that a hybrid model combining public and private blockchains is increasingly being adopted to optimize the benefits of both systems. This study is expected to serve as a reference for academics, practitioners, and policymakers in formulating optimal blockchain adoption strategies within the business sector. It also provides insights into the challenges of blockchain implementation and the potential for integration with other technologies in the future.
