The dissemination of personal data through digital media has increased significantly alongside the growing use of Quick Response (QR) Codes for various purposes, such as electronic tickets, certificates, and digital identities. Conventional QR Codes are open and can be easily scanned, copied, or manipulated by unauthorized parties. The personal data referred to in this study includes sensitive information such as full name, identity number (NIK/National ID), date of birth, address, phone number, and email address. This research proposes a layered security system that combines the Advanced Encryption Standard (AES) cryptographic algorithm with steganography using the Discrete Cosine Transform (DCT) method. The process begins with encrypting personal data using AES, converting the encrypted result into a QR Code, and embedding the QR Code into a digital image using DCT, hiding it in the image’s frequency domain. The digital images used are of fixed size and formats that preserve visual quality. System evaluation is carried out by testing the visual quality of the stego image, the success rate of QR Code extraction, and the integrity of the encrypted data. The results are expected to conceal sensitive information visually while maintaining its confidentiality, with potential applications in electronic ID cards, digital certificates, e-tickets, and other confidential documents.

This study aims to examine how the implementation of Integrated Marketing Communication (IMC) carried out by Friendshub contributes to building and strengthening brand awareness. Employing a descriptive qualitative approach and a case study method, data were collected through in-depth interviews with the core team of Friendshub and documentation of marketing activities, which were then thematically analyzed to explore communication patterns and creative strategies applied. The findings reveal that Friendshub integrates six elements of IMC as proposed by Belch and Belch (2021)—advertising, sales promotion, public relations, personal selling, direct marketing, and digital/interactive marketing—implemented across various channels such as social media, WhatsApp, email blasts, and event organization that emphasizes direct experiential engagement. The success of this implementation is supported by close communication with clients, consistent visual identity, and the adaptability of messages to audience needs, while challenges include limited budgets, dependence on client briefs, and short execution timelines. These findings highlight that consistent, creative, and adaptive IMC practices are not only effective in enhancing brand awareness but also in strengthening long-term relationships between Friendshub as a brand and its audience, thereby contributing positively to the sustainability of its image and corporate growth.

Developments in information technology have had a significant impact on business communication and negotiation processes in various industrial sectors. Technological advances such as email, video conferencing, instant messaging applications, cloud-based information systems, and other digital media have created new, faster, more efficient, and more documented communication models. This study uses a descriptive approach based on a literature review to analyze how information technology is transforming interaction patterns, strategies, and negotiation processes in the modern business environment. The results indicate that information technology plays a strategic role in increasing the effectiveness of business communication and accelerating the negotiation process. Advantages such as cost savings, time flexibility, global access, and automated documentation are the main reasons for the increasing use of digital media in the business world. However, digital negotiation also presents challenges such as the loss of non-verbal context, the risk of miscommunication, data security issues, and limitations in interpersonal relationships. The conclusion of this study confirms that successful negotiations in the digital era are greatly influenced by interpersonal communication skills, digital literacy, appropriate media selection, and the implementation of negotiation strategies that adapt to technological changes.

Advances in information technology increasingly require communities to adapt to digital communication tools, particularly email, which functions as a key digital identity for account registration, information exchange, and online transactions. Despite its importance, digital literacy remains limited among the general public, especially rural housewives, many of whom lack awareness of the need for email accounts, have limited operational skills, and are vulnerable to cyber risks such as phishing and data theft. To address this issue, a workshop entitled “Fundamentals of Using Gmail and Account Security” was conducted for the PKK women’s group in Jompo Kulon Village to improve basic digital skills and promote safe online practices. The program aimed to introduce the functions and benefits of email, assist participants in independently creating Gmail accounts, provide knowledge on securing accounts through two-factor authentication, and train participants to send and receive emails. The workshop was delivered through an interactive face-to-face approach combining short presentations and hands-on practice using participants’ mobile devices. Initial sessions explained email as a digital identity, followed by guided account creation and security setup. The final session focused on practicing email communication to reinforce understanding. The results showed high participant engagement, with most participants successfully creating Gmail accounts, understanding essential digital security concepts, and demonstrating basic email usage skills. Overall, the activity increased awareness of personal data protection and is expected to serve as an initial step in strengthening digital literacy among women, enabling them to better adapt to ongoing technological developments.

Background: In the domain of corporate governance, the separation of ownership and control generates significant agency conflicts, primarily manifesting as Earnings Management (EM). Traditional reactive auditing methods fail to detect manipulation concealed within unstructured data, leading to high agency costs and diminished stakeholder trust. Objective: This study proposes an "AI Proactive Monitoring Model" utilizing Generative Artificial Intelligence to fundamentally enhance the monitoring mechanisms of Agency Theory. Methods: The research employs a qualitative conceptual framework analysis. It synthesizes Agency Theory with the Technology Acceptance Model (TAM) and Systemic Risk Theory to construct a novel strategic governance model. Results: The proposed model shifts governance from periodic sampling to real-time, continuous analysis of total data populations. By cross-referencing structured financial data with unstructured communications (e.g., emails, contracts), the system generates "Risk Narratives" that contextualize anomalies and flag opportunistic behavior immediately. Conclusion: The integration of AI significantly reduces information asymmetry and moral hazard by creating a "panopticon" effect. However, successful implementation requires distinct regulatory frameworks to manage the systemic risks associated with algorithmic reliance.

Negotiation is a strategic communication process in which multiple parties work to reconcile differences and reach mutually beneficial agreements through the exchange of information, interests, and viewpoints. Although traditional theories emphasize analytical elements such as developing a BATNA, crafting offer–counteroffer strategies, and employing persuasive framing, recent research underscores the growing importance of interpersonal competencies in shaping negotiation success. Through a qualitative literature-based approach, this study explores how empathy, assertive communication, and emotional regulation influence negotiation outcomes, examines their relevance in digital negotiation environments, and proposes an integrated training framework for professionals and entrepreneurs. The findings reveal that empathy strengthens a negotiator’s ability to interpret emotional cues, identify underlying concerns, and build trust, thereby minimizing miscommunication. Assertive communication supports clear expression of interests and boundaries while maintaining respect, which enhances collaborative problem-solving. Emotional regulation promotes composure and cognitive flexibility, particularly in high-pressure interactions. In technology-mediated negotiations conducted via email, messaging platforms, or virtual meetings, these skills must be adapted due to limited physical cues and higher risk of misinterpretation, requiring explicit wording and intentional emotional management. The proposed model incorporates empathy training, assertive communication development, emotional regulation practices, and digital negotiation skills to cultivate adaptive and emotionally intelligent negotiators.

This study explores the role of English in supporting the academic and professional development of management students, based on the lecturer’s reflections as both lecturer and researcher. As English becomes increasingly important in global education and employment, many students are required to read academic materials, complete assignments, and communicate using English. This study focuses on how English for Specific Purposes (ESP), especially Business English, helps students build discipline-related skills and prepare for real workplace communication. Using an autoethnographic approach, the researcher collected data from self-interviews, reflective teaching journals, and informal student feedback over one semester. Thematic analysis was used to identify patterns in the lecturer’s experiences and observations. The findings show that English supports students’ academic growth by helping them understand textbooks, research articles, and business case studies. Students gained confidence in reading and presenting academic information after completing guided tasks. The results also indicate that ESP based on activities such as email writing, meeting simulations, and presentations strengthened students’ employability skills. These tasks helped students feel more prepared for internships and early career responsibilities. Additionally, the study highlights the importance of reflective teaching. By analyzing classroom challenges and student needs, the lecturer was able to improve teaching strategies, select more authentic materials, and provide better support for learners. This research shows that integrating ESP with employability goals can create meaningful learning experiences for management students. When English teaching is connected to real professional contexts, students develop both language proficiency and practical communication skills. The study also encourages lecturers to use reflection as a tool to enhance teaching quality and better support students’ academic and career preparation.

This study examines the mechanism of preparing loading documents for MT. Lucky Star 06 at the Ivo Mas Tunggal Private Terminal, managed by PT. Tarunacipta Kencana Dumai Branch. Loading documents are official records prepared during the liquid cargo loading process on a tanker to ensure operational smoothness, regulatory compliance, and administrative as well as legal requirements. The research methods employed were field research through direct observation during shore practice and library research to strengthen the theoretical foundation. The preparation mechanism begins with the shipping instruction (SI) from the shipper and voyage information from the shipowner, which are compiled into the bill of lading. Once received from the head office in Jakarta via email, the agent prepares a draft version to anticipate potential data changes during the loading process. Supporting documents include the shipping instruction, bill of lading, and MARPOL for pollution identification. The loading documents consist of three main components. The first is the cargo manifest, containing a complete cargo list, including vessel details, ports of loading/discharge, consignor, consignee, and cargo descriptions. The second is the mate’s receipt, serving as evidence of cargo acceptance by the vessel. The third is the statement of fact, which records all vessel activities from clearance in to clearance out based on the time sheet. Challenges identified include internet connection disruptions that hinder data input from surveyors or shippers, and errors caused by insufficient accuracy in data entry, particularly punctuation. Solutions applied involve continuous monitoring of operational emails and thorough rechecking of documents before submission to the vessel to ensure accuracy and completeness.

The rapid development of digital technology has brought significant benefits to the field of education, particularly through the use of academic email as an official medium of communication. However, this also creates potential security risks, especially phishing attacks based on social engineering. The low level of digital security literacy among students makes academic email accounts vulnerable to cybercrime. This study aims to implement an awareness program on academic email security, focusing on improving students’ understanding of phishing threats at SMA Islam Terpadu Rantau Prapat. The method used was an interactive workshop approach, which included theoretical sessions, demonstrations of phishing cases, simulations on identifying fake emails, and group discussions. Evaluation was carried out through pre-tests and post-tests to measure the participants’ ability to detect phishing. The results showed a significant improvement in students’ knowledge and skills, with the percentage of participants able to identify phishing increasing from 20% before the program to 82% after the program. These findings demonstrate that practice-based education is effective in building students’ digital literacy. The limitation of this study lies in the relatively small sample size and short-term evaluation. Future research is expected to expand the number of participants and integrate interactive technologies to ensure more sustainable impacts.
