This study aims to analyze the strategies used by business actors in facing local market competition through Porter's Five Forces Model approach, which includes: the threat of new entrants, the threat of substitute products, the bargaining power of suppliers, the bargaining power of consumers, and the intensity of competition between competitors. This research uses a qualitative method with a descriptive approach. Data collection techniques were conducted through in-depth interviews with three categories of informants, namely business owners, employees, and consumers. Data analysis was conducted by identifying patterns, differences, and linkages between the strategies applied and aspects of Porter's Five Forces Model. The results showed that the main strendgth in local competition lies in the high intensity of competitors and the increasing number of alternative products offered. The integration strategy between online and offline marketing is proven to help dealers reach consumers more widely and build customer loyalty. The use of social media, digital promotions, and direct-to-consumer services such as exhibitions and local community partnerships are key to adaptation in the digital era. By understanding Porter's five aspects in depth, businesses can formulate strategies that are more adaptive, innovative, and highly competitive in the local market.

This study investigates the structural relationships among Product Quality (PQ), Brand Image (BI), Word of Mouth (WOM), and Repurchase Intention (RI) to empirically understand the sequential mechanisms driving consumer loyalty in a highly competitive market. Grounded conceptually in the Stimulus-Organism-Response (S-O-R) paradigm, the research posits that PQ acts as an external antecedent influencing RI through the mediating cognitive and behavioural constructs of BI and WOM. Data were collected from a sample of 187 Weber product consumers in Surabaya and analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The empirical results confirm all hypothesized direct and indirect relationships. Specifically, PQ significantly and positively influences both BI (β=0.337, p<0.000) and WOM (β=0.351, p<0.000). Furthermore, both BI and WOM significantly predict RI, with WOM (β=0.498, p<0.000) demonstrating a markedly stronger effect compared to BI (β=0.414, p<0.000). The model successfully explains a moderate 57% of the variance in Repurchase Intention. These findings underscore the strategic imperative for management to prioritize superior product quality, which organically fosters a positive brand perception and stimulates potent word-of-mouth promotion identified as the most critical driver of repeated purchases. Future research is encouraged to integrate additional affective factors, such as customer satisfaction or perceived price fairness, to enhance the explanatory power of the consumer loyalty model.

Fishermen are an essential group in supporting national food security; however, their lives are still characterized by various social and economic challenges, such as unstable income, low education levels, and high household expenditure burdens. This research aims to provide an overview of the socio-economic conditions and welfare of Bouke Ami fishermen in the Nusantara Fisheries Port (PPN) Muara Angke, North Jakarta, through the Fishermen’s Exchange Rate (NTN) and Fishermen’s Exchange Rate Index (iNTN). The study was conducted in May–June 2025 using a descriptive method with quantitative and qualitative approaches. Data collection techniques included observation, interviews, and questionnaires distributed to 100 Bouke Ami crew members (ABK). The results showed that the majority of crew members were aged 30–39 years, had completed only junior high school education, received health services through community health centers (puskesmas), had three family dependents, and most lived in their own homes. The average total monthly income of Rp5.733.500 is considered high as it exceeds the 2025 DKI Jakarta minimum wage (UMP) of Rp5.367.381. Meanwhile, the average total expenditure of Rp5.396.761 remains below income, indicating manageable household finances. The NTN value was 1,06 in April and 1,07 in May, resulting in an iNTN of 101%, indicating that Bouke Ami fishermen in PPN Muara Angke, North Jakarta, are at a level of economic welfare classified as prosperous with slight improvement. This increase reflects a modest rise in fishermen’s purchasing power between the two months and can serve as basis for formulating policies aimed at empowering coastal fishermen.

This study aims to analyze the role of TikTok as a digital marketing tool in increasing the number of streams and musicians' income, with a case study of the viralization of the song "Mangu" by Fourtwnty. Using a qualitative approach with a case study method, this study explores the dynamics of the virality of music content on the TikTok platform and its impact on the digital music ecosystem. The results show that the virality of songs is not solely triggered by algorithms, but also by the power of emotional narratives, the relevance of lyrics to the user experience, and the active participation of the audience in the form of production. This phenomenon is driving cross-platform conversions, where TikTok users are switching to streaming services such as Spotify and YouTube, thereby increasing digital royalties and opening up live performance opportunities for musicians. Organic marketing strategies based on audience engagement have proven to be effective in creating broad and sustainable exposure, especially among the digital native generation. This research confirms that TikTok is not only an entertainment platform, but also a strategic medium in building music branding and monetizing works creatively. These findings provide important implications for independent musicians and the music industry in designing adaptive and participatory promotional strategies in an increasingly competitive digital economy.

However, this potential has not been fully optimized to strengthen the local economy. This study aims to examine strategies for strengthening the local economy through the management of bawis fish products using the 4P marketing mix (product, price, place, and promotion). This research employs a qualitative descriptive approach with data collection methods including observation, in-depth interviews with business owners and visitors, and field documentation. The findings indicate that business actors in Bontang Kuala have developed various processed bawis fish products, such as gammi bawis and dried bawis fish, marketed with pricing strategies adjusted to purchasing power. Most businesses are strategically located along the culinary tourism route, although accessibility challenges persist. Promotion strategies remain simple and limited to social media and local community support. Key supporting factors include raw material availability, high market demand, and community institutional support, while constraints include infrastructure limitations, suboptimal promotion, and raw material fluctuations. Overall, the management of bawis fish products has positively impacted community income and strengthened local economic identity. Recommendations include strengthening business infrastructure, enhancing digital promotion capacity, developing community-based business institutions, and expanding strategic partnerships among local actors.

The advancement of information technology has profoundly transformed the criminal justice system, particularly in judicial proceedings that now utilize digital platforms such as e-court and e-litigation. Although judicial digitalization aims to enhance efficiency and transparency, it simultaneously raises critical concerns regarding judicial independence in the exercise of adjudicative authority. This study employs a normative juridical approach to examine how digital transformation affects the principle of judicial independence and to reconstruct its concept in accordance with the rule of law. The analysis is based on statutory regulations, legal doctrines, and principles governing judicial power. The findings indicate that the integration of technology into judicial processes may create administrative and technological dependencies that potentially undermine the autonomy of judges in deciding criminal cases. Therefore, a redefinition of judicial independence is necessary—one that extends beyond institutional guarantees to include ethical and personal integrity aspects through the reinforcement of judicial accountability and technological transparency. This study recommends the formulation of ethical standards and technical regulations that explicitly limit administrative or external interference with judges in the digital judicial environment, thereby maintaining a balance between technological efficiency and substantive justice.

Android continues to innovate, and biometric systems particularly fingerprint sensors must operate with high efficiency. However, the main challenge lies in the communication between hardware and software, which often causes high latency, excessive power consumption, and protocol incompatibility between components. As a result, authentication speed decreases and system stability is compromised, especially on mid- to low-range devices. This study explores various implementations of Android-based fingerprint systems, focusing on how sensor modules interact with the microcontroller or Trusted Execution Environment (TEE) and the operating system through a hardware-software co-design approach to evaluate integration efficiency across all layers. The analysis reveals that conventional protocols such as Bluetooth or serial connections still cause delays, while improvements in drivers and the Hardware Abstraction Layer (HAL) can significantly reduce latency. As a solution, the researchers propose a co-design optimization approach that utilizes data flow normalization within the HAL and adopts lightweight communication protocols to accelerate the verification process. Based on the test results, this approach successfully improves efficiency—authentication time is reduced by up to 35% and power consumption decreases by approximately 15%. Therefore, the efficiency of communication between hardware and software becomes a key factor in enhancing the performance and reliability of fingerprint systems on Android devices.

The franchise business model has experienced rapid growth in Indonesia, particularly in the food, beverage, and modern retail sectors, such as Indomaret. The franchise system provides efficient business expansion opportunities for franchisors and franchisees to participate in businesses that already have established operational standards and market reputations. However, behind this development, significant legal challenges have emerged, particularly related to the unequal position between franchisors and franchisees in franchise agreements. This study aims to analyze the forms of legal protection for franchisees by reviewing the principles of fairness, balance, and legal certainty in the implementation of franchise contracts. The approach used is a normative juridical method with a case study of the Indomaret franchise partnership, which is examined through an analysis of related laws and regulations, such as Government Regulation Number 42 of 2007 concerning Franchising and Regulation of the Minister of Trade Number 71 of 2019. The results of the study indicate that there is still asymmetry of power in contract drafting, weak legal literacy of franchisees, and a lack of government oversight of agreement implementation. Therefore, regulatory reform and strengthening of oversight mechanisms are needed to ensure that franchise relationships operate fairly, transparently, and sustainably

Choosing a strategic business location is a key factor in building a successful enterprise, especially in Lautem Municipality, Timor-Leste. This area presents various opportunities for businesses such as grocery shops, small restaurants, repair workshops, and agricultural ventures. However, entrepreneurs often face challenges like poor road infrastructure, limited purchasing power, and inadequate transport access. This study developed a web-based Decision Support System (DSS) using the ELECTRE method to help business owners select the most suitable location. The system evaluates multiple location options based on important criteria such as population density, transportation access, and economic activity. By using this approach, entrepreneurs can reduce the risk of choosing an unprofitable location and improve their chances of success. The results show that implementing the ELECTRE method in a DSS is effective for identifying optimal business sites. These findings are expected to serve as a practical reference for entrepreneurs in Lospalos and nearby areas, while also supporting local economic development in the region.

The development of Islamic banking in Indonesia has introduced the murabahah contract as one of the most dominant financing products. However, in practice, this contract often gives rise to legal disputes, particularly due to default by customers who fail to fulfill their payment obligations in accordance with the agreement. This study focuses on the Palangka Raya Religious Court Decision Number 1/Pdt.GS/2024/PA.PLK, which is noteworthy because, although the substance of the claim has a strong legal basis, it was deemed inadmissible due to a formal defect in the special power of attorney. The aim of this research is to analyze how substantive aspects related to default in murabahah contracts and procedural aspects concerning the mechanism of simplified lawsuits, as well as the validity of a special power of attorney, can affect dispute resolution.This article employs a qualitative method with a normative juridical approach, encompassing legislation, conceptual analysis, and case studies. Primary data were obtained from court decisions, while secondary data were drawn from legal regulations and literature studies. The study shows that substantively, the defendant was proven to be in default for failing to fulfill payment obligations under the murabahah contract, giving the plaintiff a strong legal basis to file a claim. However, procedurally, the lawsuit was inadmissible because the submitted special power of attorney did not meet formal requirements, rendering the plaintiff’s legal representative unauthorized to act on their behalf. The implications of these findings indicate that the success of resolving Islamic banking disputes is not solely determined by the strength of the claim’s substance, but also heavily depends on compliance with the applicable civil procedural laws. Therefore, fulfilling procedural requirements is a crucial factor in ensuring the effectiveness of dispute resolution in Islamic banking.

Tourism in culturally hybrid destinations requires the integration of authentic experiences, technology adoption, and religious values to foster sustainable competitiveness. This study investigates how tourist experience quality and technology-enhanced tourism activities influence revisit intention through the mediating role of perceived halal value in Samosir, North Sumatera. A quantitative survey was conducted with 300 Muslim visitors, and data were analyzed using partial least squares structural equation Modeling (PLS-SEM). The results revealed that both tourist experience quality and technology-enhanced tourism activities significantly improved perceived halal value, which, in turn, strongly predicted revisit intention. Technology-enhanced activities exerted the strongest direct and indirect influences, confirming their role as a dominant driver of halal value creation. Mediation tests showed that perceived halal value significantly strengthened the pathways from both antecedents to revisit intentions. The model explained 67.8% of the variance in perceived halal value and 63.1% of the variance in revisit intention, indicating its substantial explanatory power. This study was limited by its focus on a single destination and its cross-sectional design, which may constrain generalizability and causal inference. Despite these limitations, the findings contribute to halal tourism literature by demonstrating the critical role of technology in reinforcing value perception and loyalty in emerging Muslim-friendly destinations. Practically, this study highlights the need for destination managers to integrate authentic cultural experiences with smart halal-compliant technologies to enhance tourist trust, satisfaction, and long-term commitment.Practically, the study provides actionable insights for destination managers and policymakers to integrate smart, halal-compliant technologies with authentic cultural experiences, thereby strengthening tourist trust, satisfaction, and sustainable competitiveness in halal tourism markets.

According to the study's findings, AMAYO Yogyakarta students can boost their interest in learning in the digital age by utilizing digital media powered by artificial intelligence (AI).

Earnings quality refers to the accuracy of a company in presenting its earnings information. It reflects the quality of the company’s financial statements, indicating whether the reported earnings can be considered reliable or not. Earnings quality is influenced by several factors, one of which is the decision-making of the board of directors (CEO). The CEO is regarded as the most powerful individual within a company, exercising authority over corporate decisions, including the disclosure of financial information. In recent times, many women have taken on the role of CEO, and their presence is no longer underestimated. The purpose of this study is to provide empirical evidence on the effect of female CEO presence and CEO education on earnings quality. The research was conducted on all companies listed on the Indonesia Stock Exchange (IDX) for the 2019–2022 period. The sample size was determined using a saturated sampling method, resulting in 2,792 observations. Data were collected using a non-participant observation method, and the analysis technique employed was multiple linear regression analysis. The results of this study show that female CEO presence and CEO education have no significant relationship with earnings quality.

This research aims to examine how betrayal is represented in the film The Last Supper (2025). The study employs a qualitative approach using John Fiske’s semiotic theory, which focuses on three levels of codes: reality, representation, and ideology. Data were collected through visual observation of the film’s scenes and analyzed to identify signs and underlying meanings within the actions of the characters. The findings reveal a total of nine betrayal scenes, segmented into 52 image shots that were analyzed in depth. These scenes primarily depict the betrayals committed by Judas Iscariot and Peter against Jesus Christ. The analysis shows that betrayal is not merely presented as a dramatic motif but is constructed as an ideological representation that reflects power relations, social pressure, and human moral dilemmas. The film serves as a cultural text that constructs meaning through visual symbols, gestures, expressions, and dialogue. As such, it can be interpreted as a form of social criticism against systems of power that influence individual behavior. Therefore, the film functions not only as entertainment but also as a discursive space that voices fundamental human issues.

In the digital era, YouTube has become a powerful platform for sharing knowledge, shaping perspectives, and encouraging critical engagement. This study explores how multimodal elements—verbal, visual, and audio—construct meaning in the educational video “Kalau Kamu Mau Punya Critical Thinking, Jangan Skip Obrolan Ini!” from the Suara Berkelas channel. Using a qualitative case study approach, the research interprets how these modes work together to support critical thinking. Data were collected through video observation, transcription, and documentation of multimodal features, then analyzed thematically using Kress and van Leeuwen’s multimodal framework and Facione’s critical thinking model. The findings show that the verbal mode structures logical arguments and rhetorical appeals, the visual mode emphasizes meaning through gestures, expressions, and text overlays, while the audio mode builds emotional engagement through tone, pauses, and background music. Together, these modes create a coherent and persuasive discourse that not only informs but also invites viewers to reflect critically. The study contributes theoretically to the understanding of multimodality in digital education and practically provides insights for educators and content creators to design more interactive, reflective, and engaging educational content.
