Jurnal Manajemen Bisnis Era Digital 2025 Asosiasi Riset Ilmu Manajemen Kewirausahaan dan Bisnis Indonesia

Social media has become a tool used by everyone. It has become a widely used tool for sharing information and as a promotional platform. In today's digital era, many MSMEs (Micro, Small, and Medium Enterprises) promote their products using social media, eliminating the need to rely entirely on conventional strategies such as direct sales in markets or stores. Marketing utilizes digital technology to achieve goals through active and measurable communication. Marketing strategies using social media are crucial because they can reach a wide range of buyers without time or geographic limitations. Sellers and buyers can interact with each other through messages, comments, and reviews. This research aimed to gain a deeper understanding of how social media influences the marketing strategies implemented by MSMEs through interviews. The results of this study concluded that social media significantly influences MSME marketing strategies and builds relationships with customers. MSMEs are expected to develop better promotional strategies in the future and learn to adapt to competition in the digital era. As a suggestion, MSMEs are advised to integrate interactive content such as live streaming and influencer collaborations to strengthen consumer engagement, as well as allocate a minimum budget of 10-15% of revenue for digital marketing training.

Sexual violence remains a pervasive human rights violation globally, with nearly one in three women experiencing physical or sexual abuse in their lifetime (UN Women, 2024). In Indonesia, the National Commmision on Violence against Women (Komnas Perempuan) reported 330,097 cases in 2024, of which 26,9% were sexual violence. Despite Law No. 12 of 2022 on the Crime of Sexual Violence (UU TPKS), gaps persist between legal enforcement and public awareness, emphasizing the need for effective advocacy. This study investigates the rol of digital media in human rights advocacy by analyzing KemenPPPA’s Instagram Reels campaign titled “Three Years Since the Enactment of the Sexual Violence Law.” Using a qualitative descriptive approach, data were collected through digital observation and documentation of the video, captions, and public comments. Framing Analysis (Entman, 1993) identified problem definitations, moral evaluations, and proposed solutions, while Normative Content Discourse Interpretation (NCDI) interpreted content based on national law and international human rights standards, particularly CEDAW. Findings show that the campaign communicates key human rights values, including victim protection, gender equality, and justice. The study highlights the potential of digital media as both an educational tool and platform for social participation, stressing participatory legal communication to complement formal law enforcement and advance women’s rights in Indonesia.

This study delves into the linguistic and ideological dimensions of cyberbullying discourse directed at TikTok creator Putri Padang within the framework of Critical Discourse Analysis (CDA). In Indonesia’s digital landscape, TikTok has become one of the prominent platform for self-expression and cultural performance, yet it also serves as a site for public shaming and moral policing. Drawing on Fairclough’s (1995) three-dimensional model, this qualitative research analyzes fifty hate comments collected from several TikTok videos featuring Putri Padang to uncover how language reproduces power relations and cultural ideologies. The findings reveal that hate comments are not random acts of aggression but structured discursive practices characterized by repetition, labeling, and moral judgment. Linguistic strategies such as mockery, objectification, and intertextual humor—exemplified by terms like “muka kotak” and “Adudu”—function as mechanisms of symbolic domination, reinforcing gendered and regional hierarchies. Moreover, the comments often invoke patriarchal values and cultural authenticity to moral criticism, positioning the target as a violator of feminine and cultural norms. The research contributes to cyber-discourse studies by extending into multimodal contexts and emphasizing the need for culturally grounded approaches to online gender-based violence.

This research explores how people use assertive speech acts in the comment section of a YouTube video titled “Democratic Candidates Debate: Education,” which was uploaded by ABC News. A qualitative method with content analysis is employed to examine how users share their thoughts, express agreement or disagreement, and participate in online discussions through assertive language. The data were collected from selected comments posted between 2019 and 2020, particularly those reacting to the candidates’ views on education. The analysis applies Searle’s speech act theory, focusing on seven types of assertive speech acts: claiming, stating, reporting, describing, informing, complaining, and concluding. A total of 24 assertive utterances were identified, with the following distribution: claiming (11), reporting (3), complaining (4), stating (2), informing (2), describing (1), and concluding (1). Among these, "claiming" appeared most frequently, indicating that many users shared strong opinions or support, especially for Andrew Yang’s stance on education. Overall, the findings suggest that YouTube serves not only as a platform for viewing content but also as a space where people actively engage in discussions, express their beliefs, and respond to public issues through language.

This research is inspired by the extraordinary success of the domestic animated film titled Jumbo, which managed to set a new record and trigger a wave of overwhelmingly positive sentiment responses on the Instagram social media platform. Its main focus is to provide a deep qualitative interpretation of audience sentiment data that was previously collected and quantitatively evaluated by Prasetia (2025) from 764 original comments, which were then filtered down to 221 samples. The approach applied involves secondary data analysis by reviewing the frequency of Prasetia's data through the lens of social identity theory and collective efficacy theory. The results of the analysis reveal that the prevalence of positive sentiment at 68.7% does not merely reflect a simple evaluation of the film but also serves as a fundamental expression of shared pride and in-group preference. Expressions of support that emphasize appreciation for the achievement and national pride over the work of local creators act as a tool for strengthening social bonds, reinforcing the national identity linked to achievements in the film sector while also demonstrating the audience's collective belief in the potential of the domestic animation industry (mastery experience). Practically, the recommendation for local film promotion strategies is to highlight narratives about shared accomplishment and national pride to build audience loyalty and continuous interaction in the digital environment.

The rapid development of technology encourages the change in crime patterns from conventional to digital through the use of electronic devices. This phenomenon makes many individuals and groups use technology not only for positive purposes, but also to gain financial gain illegally. Instagram as one of the most popular social media applications has also become a space for digital crime practices, especially through the creation of fake accounts. Fake accounts are used for various harmful acts such as online fraud, the spread of fake news, the use of identities or photos without permission, acts of bullying and negative comments that trigger conflicts, to the spread of pornographic content. This research aims to identify the forms of fake account practices on Instagram, analyze the causative factors, and evaluate the application of applicable laws, especially Law Number 19 of 2016 concerning Information and Electronic Transactions. The research method used is empirical legal research with a qualitative approach. The data was collected through interviews with investigators from the Directorate of Criminal Investigation of the Metro Jaya Police, academics, and civil society organizations (CSO). The results of the study show that the practice of fake accounts still often occurs due to low digital literacy, weak supervision from platforms, and not optimal law enforcement. Although Article 35 jo Article 51 paragraph (1) of the ITE Law has regulated the prohibition of data and identity manipulation, its implementation still faces a number of obstacles from aspects of legal substance, enforcement structure, and community legal culture. This study recommends the need for collaboration between the government and social media platforms in limiting the creation of fake accounts, improving people's digital literacy, and reformulating legal rules that are clearer and more adaptive to the dynamics of digital crime. These efforts are needed so that the protection of social media users is optimal and able to create a safe digital space.

This study aims to develop a social media-based learning platform, specifically an Instagram account (@AIK_Muh5), for Islamic Religious Education (AIK) at Muhammadiyah Junior High School, using the first two stages of the ADDIE model (Analysis and Design). The study is based on theoretical frameworks such as social media-based learning, the challenges of AIK in the 21st century, and educational theories like constructivism and connectivism. The platform is designed to offer interactive and engaging learning through visual content like infographics, educational videos, and Instagram’s interactive features (polls, stories, comments, and live sessions). This approach aims to enhance students' digital literacy, provide relevant content, and strengthen Islamic character. While the platform has potential, it faces limitations, including a lack of empirical data to measure its effectiveness, the risk of oversimplifying complex AIK material, and an unclear evaluation system. Additionally, access issues and age restrictions hinder its use. The study suggests continuous development, integration with face-to-face learning, and inclusive strategies to ensure equitable access for all students, positioning this platform as a model for AIK learning in the digital age.

Village infrastructure development plays an important role in improving community welfare. However, public opinion regarding the condition of infrastructure is often not analyzed comprehensively and based on data. This study aims to analyze public opinions toward infrastructure in Malitidari Village using the Unsupervised Learning method with the Orange application. The data were collected from public comments on social media and digital surveys, which were then processed in text format. The analysis process includes data preprocessing, tokenization, vectorization, and the application of a clustering algorithm to group opinions into several categories without prior labeling. The Orange application was used due to its ability to visualize data analysis workflows interactively and efficiently. The results of this study show that public opinions can be grouped into several main clusters: positive opinions related to the development of roads and public facilities, and negative opinions concerning delays and unequal quality of infrastructure. Based on these findings, the Unsupervised Learning method is proven effective in illustrating public perceptions of village infrastructure conditions. The results are expected to serve as a reference for the village government in planning and improving the quality of infrastructure development in Malitidari Village

Akuntansi dan Ekonomi Pajak: Perspektif Global 2025 Asosiasi Riset Ekonomi dan Akuntansi Indonesia

The implementation of the core tax administration sistem (Core Tax Administration Sistem or Coretax) in early 2025, which was expected to modernise tax services, instead sparked a wave of public criticism due to various fatal technical obstacles. The dysfunction of this sistem not only hampered administration but also gave rise to discourse on distrust of state budget management. This study aims to analyse in depth how the failure to implement Coretax has eroded public trust and damaged the fiscal social contract between taxpayers and the state. The research method uses a qualitative approach with a Critical Discourse Analysis perspective based on Norman Fairclough's model. Data was collected through netnography from public comments and interactions on social media, then analysed through three dimensions: text (micro), discourse practice (meso), and social practice (macro). The findings show that public discourse is not merely technical complaints, but a form of symbolic resistance. At the micro level, sistem dysfunction is interpreted as evidence of incompetence and alleged budget irregularities. At the meso level, the public mobilises collective memory related to past government project failures to validate their distrust. At the macro level, this signifies a violation of the principle of reciprocity, whereby the state is perceived as demanding tax compliance without providing adequate services, thereby triggering a crisis of legitimacy. The implications of this study emphasise that digital transformation of the public sector requires transparency and accountability; failure to respond to this crisis has the potential to significantly reduce voluntary tax compliance.

Social media has transformed communication patterns, with TikTok emerging as a platform where interactions are highly expressive and multimodal. This study examines the role of emojis as politeness strategies in the comments section of TikTok influencers, focusing on how these visual symbols help maintain harmonious digital communication. Using a qualitative descriptive approach, the researchers analyzed 20 emoji-containing comments from a high-engagement influencer video. The data were interpreted through Brown and Levinson’s (1987) politeness theory, supplemented by the concept of multimodality. The findings indicate that emojis significantly support both positive and negative politeness strategies. Positive politeness was dominant (around 70%), often realized through empathy, humor, and solidarity-building emojis, while negative politeness was achieved through hedging, apologies, and respectful cues. Emojis also frequently softened bald-on-record statements and enabled off-record indirectness. The study concludes that emojis are crucial in enhancing politeness, enriching emotional expression, and fostering a sense of community in TikTok interactions, highlighting their importance in the evolving landscape of digital sociolinguistics.
