Vision+ pay television. This study uses a descriptive qualitative approach to gain an in-depth understanding of Public Relations practices at MNC Channels. Data collection techniques were carried out through observation, in-depth interviews, and documentation. Data analysis used the Miles and Huberman interactive model which includes data reduction, data presentation, and drawing conclusions. The results of the study indicate that the role of Public Relations is not yet fully optimized, especially in the strategic decision-making process. Public Relations functions more as a technical implementer of communication rather than as a management advisor. This condition has an impact on the less than optimal efforts to strengthen the Vision+ brand image. Therefore, it is necessary to strengthen the role of Public Relations as an expert prescriber, communication facilitator, problem-solving facilitator, and communication technician to support the company's communication strategy and improve brand image. In addition, this study also found that internal coordination, utilization of digital media, and consistency of communication messages are important factors in building positive public perception. The lack of integration between the Public Relations function and strategic management causes the messages delivered to be not fully aligned with brand positioning

This study analyzes the urgency of digital expert testimony in strengthening the validity of electronic evidence in civil procedure law amid rapid technological transformation. The increasing use of digital communications, electronic transactions, and online documentation has given rise to new evidence in civil disputes, while its intangible and easily manipulated nature raises doubts about its authenticity and reliability. This study will focus on Decision Number 439 B/Pdt.Sus-Arbt/2016. The study relies on primary legal sources, legislation, court decisions, and secondary legal literature analyzed qualitatively. The findings show that electronic evidence is legally admissible when it meets the requirements of accessibility, integrity, authenticity, and accountability, but its probative value is highly dependent on technical validation. In the case analyzed, the petitioner's challenge to print the chat evidence was rejected because the allegations of manipulation were unsubstantiated and no expert testimony was presented to support the claim. This shows that expert testimony plays a decisive role in explaining technical aspects beyond the knowledge of the court and in strengthening the court's conviction. This study concludes that digital experts serve as a bridge between technological complexity and legal assessment, ensuring that digital evidence is evaluated objectively. The implication for courts and related parties is must prioritize the involvement of experts to promote legal certainty, factual truth, and fair dispute resolution.

This study confirms that strategic and proactive public relations communication plays an important role in managing network service disruption issues and protecting corporate reputation.

This study aims to analyze the influence of the @starbucksindonesia account's use of Instagram as a communication medium on brand image following the pro-Israel boycott. The boycott arose from Starbucks' alleged involvement in the Israeli-Palestinian conflict, which triggered a decline in its reputation and negative sentiment among Indonesians. In this situation, Instagram, as a visual-based social media platform, was utilized as a primary means of shaping public opinion and responding to the crisis. The study employed a quantitative approach using an online questionnaire survey. Respondents were 100 followers of the @starbucksindonesia Instagram account, aged 18–35, and former Starbucks customers. Data analysis was conducted using validity and reliability tests, simple linear regression, t-tests, and coefficients of determination using SPSS version 27. The results showed that all research instruments were valid and reliable. The main finding demonstrated that Instagram use had a statistically significant effect on Starbucks' brand image. The coefficient of determination value indicated a strong relationship, indicating that the majority of changes in respondents' perceptions were influenced by communication via Instagram. This research supports the Uses and Effects theory, which states that social media not only serves as an information provider but also has the ability to shape consumer perceptions and attitudes. Therefore, Instagram plays a strategic role in digital communications for crisis management and brand image restoration.

The development of social media has significant transformations in the communication strategies of retail companies, particularly in building relationships with customers digitally. In the context of increasingly intense competition, social media no longer functions merely as a promotional channel, but also an interactive space to shape engagement, brand perception, and long-term relationships with customers. TIP TOP Supermarket, as one of the modern retail players in Indonesia, utilizes Instagram as its primary digital communication channel to reach audiences, convey brand values, and build customer engagement. The majority of TIP TOP Supermarket’s customers do not yet possess high levels of digital awareness, resulting in limited engagement with TIP TOP’s activations on Instagram. TIP TOP has not yet implemented a strategic approach in managing its Instagram. This condition constitutes a challenge in Instagram management. This study aims to analyze the stages of research and diagnosis, objective, strategies, tactics, implementation, and reporting-evaluation carried out by TIP TOP Supermarket in building customer engagement. The research employs a descriptive qualitative approach within a positivist paradigm. Data were collected through in-depth interviews with seven key informants from the Marketing and Communications Division, observations, and online documentation. The findings indicate that the management of TIP TOP Supermarket’s Instagram has gone through all stages of the ROSTIR, although several aspects have not yet been fulfilled. The conclusion emphasizes the importance of building a brand identity with consistent characteristics. This study recommends the establishment of a digital community on Instagram and the adoption of a responsive approach toward customers.

In the contemporary digital marketplace, consumers increasingly face diverse product choices and brand communications. Understanding the mechanisms through which product quality and brand perception influence customer loyalty remains critical for competitive advantage. The mediating role of customer trust in this relationship has received limited empirical attention within Indonesian market contexts. This research analyzes the direct and indirect effects of product quality and brand perception on customer loyalty, with customer trust as a mediating variable, using Partial Least Squares Structural Equation Modeling (PLS-SEM) methodology on 103 respondents. A quantitative cross-sectional survey design was employed, collecting data via Likert-scale questionnaires (1-5) with 15 measurement items across four latent constructs: Product Quality (5 items), Brand Perception (4 items), Customer Trust (3 items), and Customer Loyalty (3 items). Data analysis utilized PLS-SEM via SmartPLS 3.0, including assessment of measurement model validity (outer model), structural relationships (inner model), and mediation effects through bootstrapping (5000 iterations). The outer model demonstrated adequate validity with 12 of 15 indicators loading above 0.7, and all constructs meeting composite reliability (CR > 0.7) and average variance extracted (AVE > 0.5) criteria. The inner model revealed that product quality significantly influenced customer trust (β = 0.624, p < 0.001), while brand perception showed no significant direct effect (β = 0.045, p = 0.767). Customer trust strongly predicted loyalty (β = 0.650, p < 0.001). Product quality demonstrated a significant indirect effect on loyalty through trust (β = 0.405, p < 0.001), indicating full mediation. The model explained 43.5% of trust variance and 42.2% of loyalty variance. Product quality emerged as the dominant antecedent of customer trust and loyalty, while brand perception did not significantly contribute. Trust served as the critical mechanism translating quality into loyalty. These findings suggest that companies should prioritize quality assurance and consistent delivery over brand marketing campaigns for sustainable loyalty development. The research contributes to mediation theory in consumer behavior and provides actionable strategic guidance for practitioners in emerging markets.

Digital Down Conversion (DDC) is a fundamental process in software defined radio (SDR) and digital communications, which transforms intermediate frequency (IF) signals into baseband signals. In conventional DDC designs, multipliers and look-up tables are generally employed, both of which tend to increase hardware size and power consumption. In this paper we present a Dual-Mode CORDIC-Based DDC architecture which uses the CORDIC (Coordinate Rotation Digital Computer) algorithm to eliminate multipliers. This novel architecture combines a CORDIC-based Numerically Controlled Oscillator (NCO), a CORDIC mixer, and a Cascaded Integrator-Comb (CIC) filter with a finite impulse response (FIR) com pentation filter. The NCO provides two precision modes - an 8-stage low-latency mode for speed and a 16-stage high precision mode for accuracy, giving runtime reconfigurability according to design requirements. Simulations and analysis show that the design gives highly accurate frequency translation, is efficient in hardware utilization and fully eliminates the use of digital signal processing (DSP) blocks. Overall, the architecture proposed offers a low-power, low-cost, and recon figural solution ideal for modern SDR-based applications and flexible digital signal processing systems.

Overall, the account’s management has been effective and supports two-way communication between the government and the public, though improvements are still needed in real-time interaction and creative content development to enhance engagement.

This study aims to analyze the narrative dissonance in the corporate communication of the Aqua brand, especially in the context of the crisis of meaning that arises between claims of natural purity and technical findings related to the use of borewells in the production process. Using a qualitative approach through content and narrative analysis, the study integrates two main theoretical frameworks: the Narrative Paradigm (Fisher, 1984) and Image Repair Theory (Benoit, 1995). The analysis focused on how companies are building, maintaining, and renegotiating their corporate narrative amid public pressure and consumer expectations. The results show that the legitimacy crisis arises due to the symbolic mismatch between the narrative of "purity" communicated and the operational reality revealed to the public. This tension triggered a strategic response from the company in the form of public clarification, transparency of the production process, and repositioning of messages to restore consumer image and trust. This study confirms the importance of narrative coherence and reflexivity in corporate communications, especially in an era of digital openness that demands accountability and consistency between symbolic messages and tangible practices. These findings contribute to the study of crisis communication and brand image restoration strategies, as well as a reference for companies in designing ethical, transparent, and sustainable communication to maintain legitimacy and credibility in the eyes of the public.

The study also highlights the role of digital marketing tools in enhancing the reach of the hotel's communication efforts. By utilizing platforms like Instagram, Facebook, and WhatsApp, Adhiwangsa Hotel was able to reach a broader audience, particularly among younger consumers who are more active on social media. These platforms allowed for real-time updates, engagement, and interaction with potential customers, making the event more dynamic and accessible. Overall, the success of the "So Kiss Me" event can be attributed to the hotel's effective use of integrated marketing communications, where personal selling played a significant role in delivering a more personalized and direct message to potential customers. This case study illustrates the importance of adopting a multi-channel communication strategy to effectively engage target audiences and achieve marketing objectives.

In the digital era, local governments face significant challenges in building a positive public image of regional leaders. The changing public communications landscape driven by technological advancements demands public relations (PR) strategies that are not only informative but also able to engage the emotional and symbolic dimensions of society. The main problem identified is the limited effectiveness of PR content strategies in changing public perceptions. Most content still emphasizes the delivery of factual information, but does not optimally develop narratives, symbols, and interactions that can strengthen the leadership image. This study analyzes this problem using the ADO (Antecedent-Decision-Outcome) approach. Within this framework, PR content innovation is positioned as a prerequisite factor (antecedent), digital communication strategies as the decision (decision), and the formation of the regional leader's image as the final outcome (outcome). The study was conducted using a Systematic Literature Review (SLR) of seven scientific articles that met the inclusion criteria. The analysis is supported by Image Management Theory, Government Communication Theory, and the New Public Governance paradigm, which emphasizes collaboration, transparency, and public participation in governance. Research findings indicate that innovative digital communication strategies—such as the use of social media, visualization of leadership activities, personal narratives, and two-way interactions with citizens—have a significant impact on building and strengthening a positive image of regional leaders. This approach not only increases public trust but also creates more meaningful engagement between leaders and the public. The study's findings confirm that PR plays a strategic role as a key actor in shaping public perceptions of regional leadership in the digital era. The success of image building depends not only on the quality of the message, but also on PR's creativity, consistency, and ability to adapt modern communication technology to meet the dynamics of public information needs and expectations.

The development of information technology has brought about significant changes in the social, economic, and legal life of global society. On the one hand, digitalization creates efficiency and convenience in various activities, such as financial transactions, communications, and access to information. However, on the other hand, this progress has also given rise to a new form of crime known as cybercrime. Cybercrime differs from conventional crime in that it is committed through electronic systems that can cross national borders and involve a large number of victims. This crime encompasses various forms, such as data hacking, online fraud, and malware distribution. This research aims to examine the development of cybercrime as a form of modern crime in the digital era and to assess the response of Indonesian criminal law to these challenges. The method used is normative legal, with a statutory, conceptual, and case study approach. This research also examines existing regulations, such as Law Number 11 of 2008 concerning Electronic Information and Transactions (ITE) and Law Number 27 of 2022 concerning Personal Data Protection, in addressing cybercrime issues. The research results show that although Indonesia has several regulations related to cybercrime, their implementation still faces various obstacles. Some of the main obstacles include suboptimal law enforcement, limited technology and human resources, and low levels of public digital awareness. Therefore, regulatory reform, institutional capacity development, and increasing public digital literacy are essential. This is part of a national strategy to address cybercrime comprehensively and sustainably, in order to create a safer and more trustworthy digital environment.

Rapid technological developments have penetrated various aspects of human life, including data and information security. Amidst the threat of data leaks and misuse, information protection has become crucial. One solution to maintain data confidentiality is to implement cryptography technology. Cryptography is the study of techniques to secure messages so they cannot be read by unauthorized parties. This process is carried out by encoding the original message (plain text) into an unreadable form (cipher text), which can only be understood by those who possess the key to decrypt it. This study used the Caesar Cipher algorithm, a form of classical cryptography. This algorithm uses a substitution method, where each letter in the message is shifted by a certain amount based on a predetermined key. Caesar Cipher is a symmetric algorithm, meaning the key used for encryption is also used for decryption. The security of this algorithm lies in the secrecy of the key, which is known only to the sender and recipient of the message. This method is relatively simple, but still relevant for securing data with low to medium sensitivity levels. This study used WhatsApp messages as the object to be encrypted using the Caesar Cipher algorithm. The results show that encrypted messages become unintelligible without prior decryption. This demonstrates that the Caesar Cipher can protect messages from unauthorized parties. Therefore, implementing this algorithm can be an initial solution for maintaining data confidentiality in digital communications, especially on platforms vulnerable to eavesdropping or unauthorized access. Its primary benefit is maintaining message integrity and confidentiality to prevent misuse.  

This study aims to determine the influence of marketing communications through Instagram on Generation Z's shopping interest in Makassar, with a focus on dyaozha clothing products. A qualitative approach was adopted, utilizing methods such as observation, documentation, and in-depth interviews with Generation Z consumers. The research participants included shop owners and followers of the dyaozha Instagram account. The findings reveal that marketing communications through Instagram—particularly through the use of engaging visual content, appealing design implementation, and active interaction—play a crucial role in shaping Generation Z's shopping interest. Instagram features such as Stories, Reels, interactive polls, and comment sections enable brands to connect more personally with potential buyers. Attention-grabbing content helps build initial interest, while endorsements and testimonials contribute to trust and credibility. Furthermore, consistent interaction between the brand and followers fosters emotional connection and brand loyalty. These factors collectively influence both interest and purchasing decisions among the Gen Z demographic. The study concludes that dyaozha’s strategic use of Instagram marketing communications has proven effective in influencing the shopping behavior of its target audience. Recommendations for dyaozha include the continuous optimization of Instagram's interactive features—such as Q&A sessions, behind-the-scenes content, and user-generated content campaigns—to sustain engagement and improve conversion rates. Additionally, it is suggested that dyaozha expands its reach by targeting broader market segments and utilizing data-driven content strategies to adapt to evolving consumer preferences. This research highlights the vital role of social media in modern marketing strategies, especially when targeting digitally native audiences like Generation Z.

Advertising not only serves as a promotional tool, but also reflects corporate social responsibility. This research aims to analyze the relationship between marketing strategy and the application of ethics in advertising, using a descriptive qualitative approach. Tokopedia's “Selalu Ada Selalu Bisa” campaign was used as the main case study to examine ethical communication practices in advertising. The results show that advertisements that emphasize honesty, transparency, and social empathy are able to build consumer trust, strengthen brand image, and increase loyalty. Conversely, misleading advertisements or exploitation of vulnerable groups can damage reputation and public trust. In the fast-paced digital era, a mix of formal regulation and self-regulation is important to maintain the ethics of marketing communications. This study concludes that ethics is not an obstacle to creativity, but rather a strategic foundation that strengthens business sustainability and long-term relationships with society.

The political transformation in post-New Order Indonesia has opened up space for public participation and press freedom in democratic life. In this context, mass media and social media play an important role in shaping people's political awareness. They also influence political behavior. This research aims to analyze the contribution of print and digital media in delivering political messages. The media also plays a role in building public opinion and shaping the political image of certain actors. This research examines various political communication literature and theories as well as the involvement of actors such as politicians, media professionals, and activists with a qualitative method through a literature study approach. The research proves that the media has the ability to shape socio-political reality through agenda-setting mechanisms in addition to being a means of disseminating information. Social media is now an effective campaign tool as well, with a significant influence on people's political attitudes, depending on the credibility of the political communicator, the background of the audience, and the quality of the message. That the media is a strategic instrument in modern political communication and helps determine the direction of democratic dynamics in Indonesia has been confirmed by these findings.
