Abstract

The authenticity of a nation is identified through one of the most fundamental instruments. Its authentic form is stated in the form of a signature. This short stroke that symbolizes personal identity is a unique form that is unique and only owned by each citizen of the nation. Along with the development of the era, the affixing of signatures on a digital basis has become an obstacle, considering the differences in the platforms used, in other words, initially the affixing of signatures using manual-conventional methods must now switch to digital form. Along with this, this study aims to determine the implementation of digital signatures in electronic documents to guarantee authenticity, data integrity, and non-repudiation in electronic transactions. Through a cryptographic approach, especially asymmetric encryption and one-way hash functions such as SHA and MD5, digital signatures function as legal evidence to replace manual signatures in digital communication. The method used is qualitative-descriptive with a literature study approach and theoretical study. The results show that digital signatures are not only more secure than manual signatures, but also increase efficiency and legal certainty in digital documentation systems.

Abstract

The rapid development of information technology encourages a variety of applications available on the Google Play Store. with various application categories, such as business, communication, education etc. One example of such an application is an online course application, namely Skill Academy from Ruangguru, which offers a variety of online guidance in the fields of education, self-development, and career. So from this, sentiment analysis will be carried out to understand a person's opinion and attitude towards a particular subject, theme, or entity in a text on the Skill Academy application from Ruangguru. This research aims to compare the performance of the Naı¨ve Bayes classification algorithm with the Syntetic Minority Over-Sampling Technique (SMOTE) on the sentiment of the Skill Academy application. This study shows the results of calculations without SMOTE and compares them with the results of SMOTE calculations. The results of this study are also expected to provide a better understanding of analyzing dataset imbalance on sentiment analysis results using Naıve Bayes and SMOTE techniques. In addition, it can be used in conjunction with appropriate evaluation methods to produce a more accurate model.

Abstract

The application of information systems has become a critical factor in enhancing operational efficiency and supporting effective decision-making in modern organizations. This study explores the role of information systems in improving corporate performance through a qualitative approach, utilizing a literature review and library research methods. By synthesizing insights from scholarly articles, case studies, and organizational reports, this research investigates how information systems streamline processes, optimize resource utilization, and facilitate data-driven decision-making. The findings reveal that information systems significantly contribute to automating repetitive tasks, reducing human error, and enhancing collaboration across departments. Additionally, these systems provide real-time analytics and comprehensive reports, enabling managers to make informed strategic decisions swiftly. The study also identifies challenges in information system implementation, including resistance to change, high costs, and the need for continuous training. Addressing these issues through proper planning, stakeholder engagement, and scalability considerations can maximize the benefits of information systems. This research highlights the transformative potential of information systems in corporate environments, providing valuable insights for practitioners and academics aiming to leverage technology for organizational success. Future studies are encouraged to focus on empirical validation and explore sector-specific applications of information systems to further enrich the discourse.

Abstract

Highways are among the worst communication environments. Various incidents that indicate communication failure always occur. Highways are indeed not designed as communication spaces, but communication symbols are scattered. It takes understanding and a mature attitude from communicators and communicants because they communicate more predominantly using nonverbal communication. The goal is to understand the symbols that appear through vehicles. However, communication will turn bad when the other party misinterprets the symbol. Egotistical-subjective assumptions arise that provoke emotions until physical fights inevitably occur. In this regard, this study aims to determine the factors that change the perception of road users to cause communication failure. Using qualitative methods with descriptive analysis types to reveal the facts that occur. The results of the study indicate that negative communication occurs because the ability to control road users is loose and unable to avoid it when brought to an emotional atmosphere. Meanwhile, negative communication in the form of curses or dirty words is included in the vocabulary of words in the emotional mental scope.

Abstract

In an increasingly competitive digital era, PT Soka Cipta Niaga is required to optimize its marketing strategy through marketplace platforms such as Shopee. One of the main challenges in carrying out a marketing strategy on Shopee is the selection of the right keywords, because it can affect product visibility and the effectiveness of advertising costs. This study aims to help the process by applying the MOORA (Multi-Objective Optimization on the Basis of Ratio Analysis) method in the decision support system. The MOORA method was chosen because it is able to evaluate various alternatives by objectively considering the criteria that are beneficial (benefit) and unprofitable (cost). The development of the system is carried out through structured stages using the waterfall approach, with the stages of needs analysis, design, implementation in the form of a dashboard looker studio, to the testing process using black box testing. Data were collected through observation, interviews, questionnaires, and literature studies. The result of this research is in the form of an interactive dashboard that not only displays keyword performance, but also provides the best keyword recommendations with three advanced groupings, namely prioritize and improve by 20%, maintain, and re-evaluate/reduce, based on the results of the MOORA method ranking. This system has been proven to provide more objective and consistent results compared to manual evaluations. Thus, this system can help PT Soka Cipta Niaga's digital marketing division in making decisions related to the selection of the best keywords more optimally.

Abstract

— The advancement of digital technology has encouraged the emergence of mobile-based innovations, including vehicle rental services. However, many existing applications still fail to prioritize user convenience, resulting in unintuitive interfaces, unclear information, and inefficient navigation flows. This study aims to design and develop the user interface (UI) and user experience (UX) of the Viclerent mobile application, an online vehicle rental platform that emphasizes usability, accessibility, and user comfort. The design process adopts the Design Thinking approach, which consists of five stages: Empathize, Define, Ideate, Prototype, and Test. Data collection was conducted through questionnaires distributed to potential users to identify their needs, problems, and preferences in using digital vehicle rental services. The findings were analyzed to produce design artifacts such as User Personas, Empathy Maps, Affinity Diagrams, pain points, and solution ideas. These artifacts guided the creation of Wireframes and Prototypes using design tools, ensuring that the application design was structured, intuitive, and responsive. The Prototype was then tested with users to evaluate usability, satisfaction, and effectiveness in supporting the rental process. Results indicate that the proposed design improves transparency of rental costs, simplifies booking procedures, and enhances trust through features such as real-time vehicle availability, flexible payment methods, and reliable review systems. Overall, the Viclerent UI/UX design demonstrates the potential to deliver a user-friendly, efficient, and innovative digital solution, thereby improving accessibility, convenience, and satisfaction in mobile-based vehicle rental services.
