Abstract:This study developed and evaluated a standalone, non-intrusive radio frequency identification (RFID)-based elevator access control system for a four-story residential building. The system used an Arduino Uno, an MFRC522…
RFID reader, and relay interfaces to regulate access to Floors 2, 3, and 4. Authorized card identifiers and floor permissions were stored locally, enabling offline operation without an external database or network connection. The relays interfaced only with the elevator push-button circuits and did not modify the original controller, motor drive, door mechanism, or safety system. Performance was evaluated using 47 registered cards and three unregistered cards, with each card tested 50 times, producing 2,500 authentication trials. Under the tested conditions, all registered cards were correctly authenticated according to their assigned floor permissions, while all unregistered cards were rejected. The system achieved 100% authentication accuracy, 100% correct relay activation, and 100% unauthorized-card rejection. Stable card detection was obtained at distances of up to approximately 1 cm. The first-floor button remained independent of the RFID module to preserve minimum accessibility during module failure. The proposed system provides a practical and low-cost retrofit solution for floor-specific elevator access control in small residential buildings.
Abstract:This study examines the effect of Environmental, Social, and Governance (ESG) disclosure, green investment, and sustainability reporting quality on firm value, with firm size as a moderating variable in energy sector companies…
panies listed on the Indonesia Stock Exchange in 2024. The study employed a quantitative associative approach using secondary data obtained from annual reports, sustainability reports, and financial statements. Purposive sampling produced 65 observations that met the research criteria. Data were analyzed using Moderated Regression Analysis (MRA), supported by classical assumption tests and hypothesis testing. The findings indicate that ESG disclosure does not significantly affect firm value. In contrast, green investment and sustainability reporting quality have positive and significant effects on firm value. Firm size also has a positive and significant direct effect on firm value. However, firm size does not moderate the relationship between ESG disclosure, green investment, or sustainability reporting quality and firm value. Simultaneously, ESG disclosure, green investment, and sustainability reporting quality significantly affect firm value. The first regression model explains 36.0% of the variation in firm value, while the moderation model explains 74.4%. These findings imply that energy sector companies should prioritize concrete green investment initiatives and improve the quality, completeness, and credibility of sustainability reporting to strengthen market value and stakeholder confidence.
Abstract:Muaro Sentajo possesses the potential to be developed as a production hub for native orchid species due to its location within the natural habitat of orchid species in Kuantan Singingi Regency, directly bordering the Sentajo…
tajo Raya protected forest. Furthermore, the village has an underutilized female labor potential, organized within the Family Welfare Movement (Pemberdayaan dan Kesejahteraan Keluarga / PKK) as the foundational collective for rural women in Muaro Sentajo. This initiative aims to provide knowledge on native orchid species, cultivation techniques, integrated systems with stingless bees (kelulut), and digital marketing. The program implemented a Participatory Action Research (PAR) approach, consisting of asset mapping, practical cultivation workshops, e-commerce platform development, and four months of intensive mentoring. This empowerment program successfully established an active orchid breeding group managing more than 15 native orchid species. Additionally, 83.66% of the participants demonstrated proficiency in operating digital marketing channels (Instagram and Shopee), resulting in the first independent commercial sales of local orchid products. The integration of local ecological assets with modern digital marketing proved effective in enhancing the economic independence of rural women and promoting sustainable community development.
Abstract:This study aims to examine the influence of User-Generated Content (UGC) on the TikTok platform on Brand Trust and the Decision to Choose a Higher Education Institution, with Brand Authenticity serving as the mediating variable.…
ariable. This study employs an explanatory quantitative approach. Data were collected via an online survey of a purposive sample comprising prospective students or first-year students (aged 17–21) who actively use TikTok and interact with university-related content. Data analysis was conducted on a minimum of 250 respondents using Partial Least Squares (PLS)-based Structural Equation Modelling (SEM) with the aid of SmartPLS software. The results of the outer model testing showed that all indicators used in the questionnaire were valid and reliable. Hypothesis testing confirmed that User-Generated Content has a direct, positive and significant effect on Brand Authenticity, Brand Trust and Choice Decision. Furthermore, Brand Authenticity also has a positive and significant effect on Brand Trust and Choice Decision. Mediation analysis revealed that Brand Authenticity acts as a partial mediator, bridging the influence of UGC on Brand Trust and Choice Decisions. This study confirms that user-generated organic content on TikTok is a crucial instrument in building trust and influencing the academic decisions of Generation Z. Higher education brands that are authentically represented through UGC will find it easier to win the trust and preference of prospective students.
Abstract:This study examines how a non-diasporic public in the Global South engages with a foreign election in which it holds no vote, no residence, and no direct material stake. Rather than asking how Indonesian netizens represent…
nt Zohran Mamdani, the first Muslim Mayor of New York City, it asks what talking about Mamdani does for these netizens as members of their own polity, and develops the concept of comparative civic imagination: the use of a foreign political figure as a discursive instrument for evaluating, criticising, and re-imagining one’s own democracy. The study applies qualitative Computer-Mediated Discourse Analysis (CMDA) to public Indonesian-language discourse about Mamdani on platform X between 1 November 2025 and 30 June 2026, drawing on a purposively constructed corpus of 213 units—134 citizen-account units as the analytical core and 79 media-account units as contextual triangulation—recoded by comparative function and affective register rather than by stance toward the figure. The findings show that Indonesian netizens engage Mamdani through a comparative architecture organised by the vernacular frame “Mamdani Indonesia” (45% of citizen units) and enacted through three repertoires: analogical personification, institutional benchmarking, and counterfactual transposition. The discourse is animated by civic despair—crystallised in the idiom “Indonesia could never”—which operates as a participatory rather than an apathetic affect, while a domestic value-compatibility filter of doctrinal, sectarian, and purity tests renders the admired model discursively non-transferable, closing a recursive loop theorised here as a digitally networked spectre of comparisons. The article shifts the analysis of transnational digital engagement away from cosmopolitan and diasporic assumptions toward the vicarious engagement of non-diasporic publics, re-theorises despair as a mode of civic engagement, and recovers Benedict Anderson’s spectre of comparisons for platform-era political communication in the Global South.
Abstract:This study is motivated by the importance of studying person deixis in literary works to understand the relationship between speakers, listeners, and the context of utterances in a novel. The purpose of this study is to…
describe the forms and use of person deixis in the novel Mak Comblang Cinta Babe by Ditta Arieska. This study employed a descriptive qualitative method using reading, note-taking, and data classification techniques related to person deixis. The data source consisted of dialogues and narrations found in the novel. The results showed that first-person, second-person, and third-person deixis were used by the characters according to communication situations and relationships among the characters. First-person deixis was the most dominant form because it frequently appeared in conversations between characters. This study concludes that the use of person deixis in the novel helps clarify the roles of characters and build communication within the story.
Abstract:The economic structure of Aceh Province is still dominated by the agriculture, forestry, and fisheries sectors, while the contribution of the manufacturing industry sector is relatively lagging. This condition indicates…
that the structural transformation process in Aceh has not yet taken place optimally, so that the economic growth that occurs tends to be quantitative, marked by an increase in aggregate output, but does not fully reflect an increase in the quality of the economic structure. This study aims to analyze the influence of the agriculture, manufacturing industry, and mining sectors on the growth of the Regional Gross Regional Domestic Product (GRDP) of Aceh Province. The approach used is quantitative with secondary data sources from the BPS of Aceh Province. This study uses panel data which is a combination of cross-regional data and time series data from 2019 to 2023. The results of the study indicate, first; the agricultural sector has a positive effect on GRDP. This is based on the probability value of the agricultural sector variable, which is 0.002. This value is smaller than 0.05. Second; the industrial sector has no effect on GRDP. This is based on the probability value of the industrial sector variable, which is 0.610. This value is greater than 0.05. Third; the mining sector has a positive effect on GRDP. This is based on the probability value of the mining sector variable, which is 0.001. Fourth; The agricultural, industrial and mining sectors have a joint influence on the dependent variable, namely GRDP in Aceh Province
Abstract:This study aims to analyze the effect of Price Earning Ratio (PER), Debt to Equity Ratio (DER), and Current Ratio (CR) on firm value, with firm size as a moderating variable, in industrial sector companies listed on the…
Indonesia Stock Exchange during the 2022–2024 period. This study employed a quantitative approach with an associative method. The data used were secondary data obtained from companies’ annual financial reports. The sample was determined using purposive sampling, resulting in 44 companies with a total of 132 firm-year observations. The data were analyzed using Moderated Regression Analysis (MRA), supported by classical assumption tests, correlation coefficient analysis, coefficient of determination analysis, simultaneous testing, and partial testing. The results of the moderation model show that firm size has a positive and significant effect on firm value, with a significance value of 0.043. Meanwhile, PER, DER, and CR do not have a significant effect on firm value after firm size and the interaction variables are included in the model. The moderation test results indicate that firm size is unable to moderate the effect of PER, DER, and CR on firm value, as all interaction variables have significance values greater than 0.05. Although PER has a positive and significant effect on firm value in the first model, this effect is no longer significant in the moderation model. The coefficient of determination in the moderation model is 12.1%, indicating that the model’s ability to explain variations in firm value remains limited. These findings indicate that firm size is a more dominant factor in explaining firm value than PER, DER, and CR in the moderation model.
Abstract:This study aims to analyze newsroom convergence processes and newsroom models implemented by Tribun Pekanbaru and Riau Pos, while also examining how newsroom convergence is utilized as an economic strategy to maintain the…
e sustainability of local media businesses amid digital disruption. The research employed a qualitative descriptive approach through in-depth interviews, observation, and documentation studies involving newsroom managers, editors, and journalists from both media organizations. The findings indicate that Tribun Pekanbaru and Riau Pos have adopted different newsroom convergence strategies. Tribun Pekanbaru has implemented an integrated newsroom model that combines Cross Media Newsroom and Integrated Media Newsroom approaches, emphasizing digital-first production and multi-platform content distribution. Meanwhile, Riau Pos continues to maintain a separated newsroom model between print and digital divisions, reflecting a gradual adaptation process toward digital transformation. The study further reveals that these differences are influenced not only by technological factors and organizational culture but also by economic considerations. Tribun Pekanbaru develops an integrated newsroom to improve production efficiency and expand digital content monetization, while Riau Pos maintains separated newsrooms because print media remains a significant source of company revenue. This study concludes that newsroom convergence has evolved beyond a technological transformation into an economic adaptation strategy for local media organizations. The findings suggest that newsroom convergence enables media companies to improve operational efficiency, broaden audience reach, optimize resource utilization, and strengthen business sustainability in an increasingly competitive digital environment.
Abstract:This study aims to examine the role of competition law in regulating corporate conduct, protecting consumers, and enhancing economic efficiency in contemporary market economies. Amid increasing market concentration, digital…
tal platform dominance, and the emergence of data-driven business models, competition law has become an essential regulatory instrument for ensuring fair competition, safeguarding consumer interests, and promoting sustainable economic development. This study employs a Systematic Literature Review (SLR) based on the PRISMA 2020 framework. Relevant literature was systematically collected from six major academic databases, namely Scopus, Web of Science, ScienceDirect, SpringerLink, Emerald Insight, and Taylor & Francis Online. The review process included identification, screening, eligibility assessment, and inclusion stages. A total of 78 peer-reviewed articles published between 2015 and 2025 were selected and analyzed using thematic synthesis techniques. The findings reveal that competition law performs four interconnected functions. First, it serves as a regulatory mechanism that shapes corporate behavior and prevents anticompetitive practices, including monopolization, cartel agreements, price-fixing, and abuse of dominant positions. Second, competition law enhances consumer welfare by promoting competitive prices, product quality, innovation, and consumer choice. Third, effective competition policy contributes to allocative, productive, and dynamic efficiency, thereby supporting long-term economic growth. Fourth, digital markets introduce new challenges associated with data concentration, platform dominance, network effects, and algorithmic pricing, requiring adaptive regulatory frameworks and strengthened institutional capacity.This study contributes to the literature by integrating Economic Efficiency Theory, Consumer Welfare Theory, Competition Policy Theory, and Regulatory Governance Theory into a comprehensive analytical framework that explains the relationship between competition law, corporate conduct regulation, consumer protection, and economic efficiency.The findings provide policy recommendations for competition authorities and governments, particularly in developing economies, regarding digital competition governance, institutional strengthening, cross-border enforcement cooperation, and data-driven market regulation.Unlike previous studies that focus on isolated dimensions of competition law, this research offers a holistic synthesis of legal, economic, consumer welfare, and governance perspectives. It further highlights how competition law can address emerging challenges in the digital economy while simultaneously promoting consumer protection and economic efficiency.
