A Structural Equation Modeling (SEM) Approach to Examine The Impact of Gold Futures Price Spillovers, Dividend Announcements, and Investor Attention on Abnormal Returns among 32 Indonesian Listed Companies Distributing Dividends in 2024
The purpose of this study is to examine the effects of investor interest, dividend announcements, and spillovers in the price of gold futures on abnormal returns among 32 Indonesian listed businesses that paid dividends in 2024. The study examines the direct and indirect correlations between the variables using a quantitative approach and the Structural Equation Modeling (SEM) technique with Partial Least Squares (PLS) estimate in SmartPLS 3.0. The Indonesia Stock Exchange (IDX), corporate financial reports, and worldwide gold market statistics were the sources of secondary data. Trading volume was used as a stand-in for investor attention, and abnormal returns were measured using an event-study framework with a two-day window surrounding the cum-dividend date. The findings indicate that neither dividend announcements nor spillovers in the price of gold have a statistically significant impact on abnormal returns. While there is a weak positive correlation between dividend announcements and gold prices, there is a negative correlation, indicating a safe-haven substitution effect where investors move away from stocks as gold prices rise. Furthermore, investor attention does not mediate the relationship between the independent variables and the dependent variable, nor does it significantly affect abnormal returns. While investor attention shows very low predictability (R² = 0.002), the model shows a moderate explanatory power for abnormal returns (R² = 0.434) and a high predictive relevance (Q² = 0.435). Overall, the results show that the Indonesian capital market reacts to corporate and macroeconomic information primarily through direct effects rather than behavioral mediation. By emphasizing the restricted function of investor attention as an information-transmission channel, this study adds to the body of knowledge on behavioral finance and spillover dynamics in emerging countries. To improve the explanatory power of abnormal return models, it is advised that future research incorporate more comprehensive behavioral or sentiment factors.

Analysis of Traffic Performance and Handling Scenarios in the Malang Station Area, Kota Baru
The Malang Kota Baru Station area is currently experiencing traffic performance problems characterized by high delays and low speeds, especially on the Trunojoyo 1 Road and Trunojoyo 2 Road sections. This condition is influenced by high side obstacles in the form of on-street parking and loading and unloading activities. This study aims to analyze the performance of the existing road network and formulate effective traffic management and engineering scenarios in improving regional traffic performance. The analysis was carried out by modeling using PTV Vissim software through the calibration and validation stages using the Geoffrey E. Havers (GEH) statistical test. The results of the analysis of existing conditions showed an average delay of 168 seconds, network speed of 13.6 km/h, total mileage of 24,120 kend-km, and total travel time of 1,774 vehicles/hour, which indicates that the performance of the road network is in the poor category. Improvement efforts are carried out through several traffic management and engineering scenarios, including moving on-street parking to off-street, repairing pedestrian facilities, adding signs and repairing road markings, as well as regulating the separation of access in and out of goods and passengers. The results of the proposed scenario simulation showed an improvement in road network performance, namely an increase in network speed to 22.04 km/h, a decrease in average delay to 90.91 seconds, a decrease in total travel time to 1,160.59 vehicles/hour, and an increase in total mileage to 25,574 kend-km. Thus, the proposed traffic management and engineering scenario has proven to be effective in improving traffic performance in the Malang Kota Baru Station Area.
Relative Predictive Accuracy of Machine Learning-Enhanced Long Memory Volatility Models for Modeling Nigeria Energy Data
This study investigates the relative predictive efficacy of machine learning-augmented long memory volatility models in analyzing Nigeria's energy statistics from January 1960 to December 2024. Utilizing monthly energy pricing information sourced from the Central Bank of Nigeria, the research employs thorough econometric and computational methods to evaluate the persistence of volatility, significant structural changes, and long-term dependencies existing within the energy data of Nigeria. Initial assessments show that raw energy data display non-stationarity, structural volatility, and clustering phenomena, with the Augmented Dickey-Fuller, Phillips-Perron, and KPSS tests affirming non-stationarity in the level data and stationarity in the returns data. The analysis of structural breaks utilizing the ruptures algorithm discovers eight notable breakpoints that align with key policy changes, worldwide oil crises, and organizational transformations in Nigeria’s energy sector. To represent the noted persistence and long memory, established econometric models such as ARFIMA, FIGARCH, and HYGARCH are estimated and then combined with Artificial Neural Networks (ANN) and Support Vector Regression (SVR). The outcomes demonstrate that hybrid models significantly exceed the performance of their isolated versions, with ARFIMA–ANN and FIGARCH–ANN showing the lowest Mean Squared Errors at 0.034 and 0.035 respectively. The ANN consistently shows a greater capability to capture nonlinear volatility patterns, while SVR demonstrates a moderate level of success. The results highlight that integrating long-memory stochastic models with machine learning frameworks provides strong predictive performance for complex energy series that depend on different regimes. These findings have significant consequences for the formulation of energy policies, management of volatility, and investment strategies in Nigeria's transforming energy sector. The study concludes that econometric models enhanced by machine learning are vital for developing adaptable forecasting systems in emerging markets facing structural and policy changes.
Implementing Green Marketing Communication Strategies to Build Corporate Reputation and Consumer Trust: A Qualitative Case Study Orientation in Manufacturing Companies in Tangerang City
Environmental sustainability communication has become an essential corporate strategy, particularly within manufacturing sectors in emerging economies. This study explores how manufacturing companies in Tangerang City, Indonesia, implement green marketing communication strategies and how these strategies influence corporate reputation and consumer trust. Using a qualitative multiple-case study approach, data were collected through semi-structured interviews with 27 participants, including marketing managers, sustainability officers, consumers, NGO representatives, and government officials, supplemented with document analysis and field observations. Thematic analysis identified three dominant communication strategies: informational, emotional, and participatory green communication. The credibility of these strategies is shaped by transparency, message consistency, evidence-based claims, and alignment between communication and environmental practices. Findings reveal that firms adopting high-transparency green communication experience stronger reputation enhancement and improved consumer trust, while firms with inconsistent environmental performance face skepticism and accusations of greenwashing. A conceptual model is proposed describing the pathways through which green communication enhances trust and reputation. This study contributes to the literature by integrating signaling theory, green marketing theory, and trust theory to explain communication credibility in the context of developing countries. Practical implications are offered for manufacturers seeking to strengthen sustainability communication and legitimacy.
Comparing Internal and External User Perceptions of a National Research Funding Information System (NRFIS): A Comparative Study
Digital transformation in the public sector requires information systems that provide consistent and equitable services to diverse stakeholder groups. A National Research Funding Information System (NRFIS) has become a strategic digital platform for managing research funding processes end-to-end across government institutions, universities, and research organizations. While previous evaluations have examined such systems using structural models, limited attention has been given to differences in perceptions between internal stakeholders and external research stakeholders. This study compares user perceptions regarding System Quality (SY), Information Quality (IQ), Service Quality (SQ), Use (UE), User Satisfaction (US), and Net Benefits (NB) between internal and external users of NRFIS. A total of 335 respondents participated, comprising 290 external stakeholders and 45 internal stakeholders. Descriptive results show that internal users consistently reported higher perceptions across all constructs: SY (4.28 vs. 3.94), IQ (4.42 vs. 3.99), SQ (4.39 vs. 3.87), UE (4.42 vs. 3.97), US (4.47 vs. 3.98), and NB (4.56 vs. 3.95). Chi-Square tests confirm statistically significant differences across all constructs (p < 0.01). Mann–Whitney U tests further validate substantial median differences (all p < 0.001). These findings demonstrate robust perception gaps between user groups, highlighting the need for improved onboarding, training, and support mechanisms for external stakeholders. This study contributes to digital governance literature by revealing structural disparities in user experience and provides policy recommendations for enhancing inclusiveness and effectiveness of NRFIS-based research funding services.
Digital Marketing Strategy For Market Visibility In Regulated B2b Services: A Case Study of A Hazardous Waste Transportation Firm In Indonesia
This paper will focus on how lack of digital marketing will limit the market presence and acquisition of clients in controlled business-to-business (B2B) service companies. Digital presence in the modern B2B procurement has ceased to be a discretion tool; instead, it is a legality-checking mechanism and supplier pre-screening tool at the initial stage. It is a single-case study with a qualitative design that seeks to examine PT Surya Cipta Wisesa, which is a hazardous waste transportation company in Indonesia that has low digital visibility, despite having good operational backgrounds. The information was gathered in the form of semi-structured interviews with internal participants and buyer-side informants, competitor digital audits, and document analysis. Results show that the major problem of the firm is not a lack of operations but a lack of legitimacy signalling: valuable resources cannot be seen when digitally mediated buyer screening occurs, which results in systematic non-consideration in sets of consideration. The internal evidence shows that the regulatory sensitivity and document management limitations- not cost is the major obstacle to the development of the digital presence. The paper proves that the way that digital marketing in controlled B2B settings works is as a legitimacy infrastructure, and not a promotional practice. It has proposed a gradual, legitimacy-first digital approach that is clearly defined in terms of definition of done and key performance indicators in each of the implementation phases. The study adds to the body of knowledge on B2B marketing by conceptualizing the digital absence as a strategic capability gap and provides useful recommendations on SMEs functioning in regulated markets of the emerging market.
Resilience of Alpha Generation: Digital Resiliency, Organizational Culture, and Talent Management
Digital transformation and changes in global work dynamics are driving the emergence of Generation Alpha as a future workforce group with digital-native characteristics, visual orientation, and high expectations for flexibility and value alignment. These conditions demand a new understanding of work resilience that relies on structural stability and sustainable adaptability. This study aims to examine the influence of digital readiness, organizational culture, and talent management strategies on the resilience of Generation Alpha in the workplace. The method used is a qualitative literature study by analyzing reputable scientific articles that discuss work resilience, digital transformation, organizational culture, and talent management across organizational contexts. The results of the synthesis show that digital readiness plays a role as a foundation for resilience through strengthening self-efficacy, adaptive learning, and psychological resilience, although it has the potential to pose a risk of self-regulation if not balanced by organizational support. An adaptive, ethical, and learning-oriented organizational culture has been proven to strengthen the psychological safety and work attachment of Generation Alpha. Flexible and nonlinear talent management strategies become an institutional instrument to convert adaptive potential into long-term resilience. This study contributes to the development of the Alpha Generation resilience conceptual framework and provides practical implications for organizations in designing sustainable human resource strategies in the digital age of work.
Business Performance Analysis And Valuation: Accounting Treatment Implications In Indonesia's Carbon Credit Industry
This study examines how accounting treatment choices for special funding schemes affect financial performance and valuation in Indonesia's emerging carbon credit industry. Using PT. Argustara Pilar Utama as a case study, a forestry-based carbon credit company operating under a unique funding arrangement where a single investor fully finances project operations in exchange for fixed-price carbon credit offtake, the research employs quantitative financial analysis methodology including ratio analysis and Discounted Cash Flow (DCF) valuation. Two accounting scenarios are evaluated: Scenario A recognizing investor funds as revenue under IFRS 15, and Scenario B recognizing funds as equity under IAS 32. The findings reveal substantial financial implications from accounting treatment choice. Scenario A produces cumulative positive EBIT of IDR 129.37 billion (2025-2034), Interest Coverage Ratio of 11.37x qualifying for Aa2/AA credit rating, and Enterprise Value of IDR 116.28 billion with WACC of 8.49%. Conversely, Scenario B generates cumulative negative EBIT of IDR 95.60 billion, negative Interest Coverage Ratio triggering D2/D distressed rating, and negative Enterprise Value of IDR 43.99 billion with elevated WACC of 22.81%. The equity value differential between scenarios reaches IDR 160.27 billion. This study concludes that revenue recognition under IFRS 15 is the superior treatment, as net shareholder value of IDR 75.32 billion after tax significantly exceeds zero value under equity recognition, while recommending complementary tax optimization strategies to mitigate double taxation exposure.

A Comparative Analysis of Financial Performance and Stability Between Indonesian Sharia Bank (BSI) and Bank Mandiri From 2020 to 2024
This study aims to assess and describe the financial performance of Bank Mandiri and Indonesian Sharia Bank (BSI) based on the RGEC analysis results during the period 2020–2024. The research method used is quantitative with a descriptive quantitative approach. The population of the study includes all banks registered and operating in Indonesia during the 2020–2024 period, or more specifically certain banks such as conventional banks and sharia banks. The samples selected are Bank Mandiri as the representative of conventional banks and Indonesian Sharia Bank (BSI) as the representative of sharia banks for the 2020–2024 period. The sample selection is based on relevance, availability of data, and representation of each bank type. The results show that Bank Mandiri demonstrates superior performance compared to Indonesian Sharia Bank (BSI) on most key RGEC indicators. Bank Mandiri maintains asset quality with significantly lower NPF, as well as records better efficiency in asset and capital utilization through higher ROA and ROE. Additionally, Mandiri’s operating margin (NOM) is much stronger and more stable. Although both banks have very strong capital adequacy (CAR) and good governance (GCG), operational efficiency (BOPO) remains a challenge for both, even though BSI shows slightly better BOPO figures. Overall, Mandiri is more aggressive in financing distribution and efficient in generating profit, while BSI is still in the process of post-merger stabilization with reasonably healthy performance but with room for improvement in operating margin and efficiency.
Formulating An Effective Marketing Strategy For Warung Nasi Ambu Rini Through The Optimization of Stp And Marketing Mix (7p)
This paper investigates marketing issues of Warung Nasi & Sate Ambu Rini which is a traditional Sundanese Restaurant in Bandung and comes up with a well-rounded marketing strategy that will help fill in the gaps. Although the quality of products and customer satisfaction with current customers are high, the warung cannot convert this to the wider awareness of the product and customer attraction. It has used a single case study where the research is conducted qualitatively using thematic analysis. In-depth interviews with 16 respondents of four categories of stakeholders (owner, employees, current customers, and potential customers) and six hours of non-participant observation were used to gather primary data. Secondary data comprised menu documentation, Instagram and Tik Tok social media analytics, GoFood data of the merchant dashboard, and photographs of the physical environment. The main results indicate that there is a critical gap in awareness (walk-in customers are zero and the social media reach decreases to -64.1% after 90 days), positioning communication (professional branding creates higher price expectations (Rp 35,000-45,000) than actual prices (since the minimum price is Rp 15,000)), delivery channel (nothing is commissioned through GoFood), targeting (students and young professionals are underrepresented), and promotion (the Instagram engagement rate is 0.32 The research suggests the positioning of the company in a Premium Feel, Everyday Price and the recommendations given are reflecting GoFood menu optimization, regular social media postings with price-inclusive information, systematic referral plans and exterior signage change. A measurement framework somewhat based on SMART would provide accountability in implementation.

Financial Feasibility of Small Scale Liquefied Natural Gas Carrier (SSLNGC) Investment: A Capital Budgeting Analysis For PT Bahtera Adhiguna Putera (BAg)
Indonesia’s target to achieve net zero emissions by 2060 requires a strategic shift from coal to cleaner energy sources, with Liquefied Natural Gas (LNG) serving as a key transitional fuel. PT Bahtera Adhiguna Putera (BAg), a subsidiary of PT PLN Energi Primer Indonesia (PLN EPI), plays a vital role in energy logistics but currently lacks the fleet capacity to transport LNG. To address this gap, this study evaluates the financial feasibility of investing a Small Scale Liquefied Natural Gas Carriers (SSLNGC) through a capital budgeting approach. The research uses both qualitative and quantitative methods. PESTEL analysis is applied to assess the external environment and operational readiness, while capital budgeting tools such as Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period, and Weighted Average Cost of Capital (WACC) are used to evaluate financial performance. The study tests several financing structure which is using 100% internal cash for Scenario 1 and mixed financing for Scenario 2 which ratio is 20% internal cash and 80% SHL scenario. A sensitivity analysis is also conducted to identify the most critical variables affecting investment outcomes and to measure the project’s financial resilience under different market conditions. The results show that the SSLNGC investment is both technically and financially feasible. The vessel’s capacity is suitable for port depth limitations and LNG demand in the targeted region. Financially, the investment is feasible, and the most optimal financing structure is Scenario 2 because has smaller WACC, higher NPV values, higher IRR compared to the WACC, and a reasonable payback period, confirming the project’s profitability. This also supported by the smaller value in the Scenario 2 sensitivity analysis calculation compared to Scenario 1. To keep the project profitable in the long term, BAg needs to ensure all the financial and operational key variables remain the same as the overall feasibility calculation is highly dependent on those variables.

Study Phytoplankton as a Bioindicator of Asahan River Water Quality
This study aims to determine the types of phytoplankton, phytoplankton abundance, factors that influence phytoplankton life and the quality of the Asahan River based on phytoplankton abundance. The method used is descriptive. The results of the study in the waters of the Asahan River obtained 13 types of phytoplankton, with a species abundance of 4875 ind/L. The quality of the Asahan River is moderately polluted as seen from the species abundance value which ranges from 1,000-10,000 ind/L and environmental parameter values, namely temperature 28.66 ˚C, brightness 6.26 m and DO 7.19 mg/l is optimal for the growth and development of phytoplankton while the salinity of 31.22 ˚/˳, pH 6.7 and BOD 2.7mg/l are below the standard quality of the Asahan River for marine biota according to the Decree of the Minister of Environment and Forestry No. 51 of 2004.
An Ergonomic Evaluation of Mosque Ablution Areas (Shadirvans): A User Perception Study
Mosque ablution areas (shadirvans) play a critical role in supporting ritual purification; however, their design is largely unstandardized and rarely evaluated from an ergonomic perspective. This study investigates the effectiveness of existing shadirvan designs by assessing user perceptions of comfort, safety, hygiene, and usability. A questionnaire-based survey was administered through structured interviews with 200 male users across 15 mosques in Istanbul, Türkiye. Fourteen Likert-scale items were used to evaluate key design and functional aspects of shadirvans. Descriptive analyses and multivariate analyses of variance (ANOVA) were conducted to examine the effects of demographic factors and mosque-specific design characteristics on user perceptions. The results indicate that while shadirvans are generally preferred over alternative ablution solutions, their performance is inconsistent and often insufficient. Common problems were identified in footwear management, water splashing control, and the organization of wet and dry zones. Traditional features such as shared clogs were largely perceived as uncomfortable and unhygienic. Statistical analyses revealed that user perceptions were predominantly influenced by the mosque itself, rather than by demographic characteristics, highlighting the strong impact of design variability. These findings provide empirical evidence that the absence of standardized design guidelines leads to significant differences in usability and user satisfaction. The study underscores the need for evidence-based, user-centered design standards to improve comfort, hygiene, and safety in mosque ablution facilities.
Designing Integrated Urban Agriculture Systems for Spatial Efficiency and Environmental Sustainability in Dense Urban Neighborhoods
Rapid urban densification in cities of the Global South has intensified land scarcity and constrained the provision of green open spaces, particularly in compact residential neighborhoods. In such contexts, community-based urban agriculture has emerged as an adaptive response to environmental, social, and spatial challenges. While existing studies widely acknowledge the multifunctional benefits of urban agriculture, empirical investigations that systematically examine its spatial logic and integration within dense built environments remain limited, especially in Southeast Asian cities. This study aims to reframe community-based urban agriculture as an integrated socio-spatial and environmental infrastructure embedded within compact urban fabrics. Using a case study approach, the research investigates urban agriculture practices in Kemantren Gondokusuman, Yogyakarta, Indonesia. Data were collected through field mapping, spatial documentation, and descriptive–quantitative analysis focusing on spatial typologies, distribution patterns, green open space ratios, and system integration. The results identify 22 spatially distributed urban agriculture sites operating across private yards, residual spaces, and communal facilities, with a density of approximately 0.055 sites/ha in an area characterized by a green open space provision of only 14.5%. Findings reveal that urban agriculture functions as a micro-scale environmental infrastructure through the integration of spatial efficiency, production systems, environmental functions, and community-based operational mechanisms. Rather than compensating for green space deficits through land expansion, environmental performance is achieved through functional intensification of fragmented spaces. The study proposes an integrated urban agriculture model that synthesizes these interdependent systems, contributing a design-oriented framework for sustainable built environments in dense urban neighborhoods. This research advances-built environment sustainability discourse by demonstrating how urban agriculture can operate as a scalable, spatially integrated strategy for enhancing environmental and socio-spatial performance in compact cities.
The Role of the Principal as a Leader in Shaping Effective Schools: A Multi-case Study at MAN 1 Tulungagung and SMAN 1 Kedungwaru
This study aims to investigate the determinant role of the principal as a leader in reconstructing a quality culture towards an effective school. Employing a qualitative approach with a multi-case study design, the research was conducted at two sites with distinctive characteristics: MAN 1 Tulungagung (based on religious values) and SMAN 1 Kedungwaru (based on professional-secular standards). Data were collected through in-depth interviews, participant observation, and documentation studies, which were then analyzed using the interactive model by Miles, Huberman, and Saldana. The results reveal a substantive finding in the form of a "Hybrid-Integrative Leadership Model" that synergizes three strategic roles cyclically. First, as a Motivator, the principal builds teacher resilience through distinct approaches: Spiritual-Paternalistic Leadership (worship-value based) in the Madrasah and Instructional-Technocratic Leadership (meritocracy-based) in the public school. Second, as an Innovator, the principal acts as a system architect who institutionalizes change ideas into strategic documents and organizational culture. Third, as an Administrator, the principal serves as a strategic risk manager who dares to make calculated decisions for resource efficiency. The study concludes that school effectiveness does not arise from a single managerial adoption, but from the principal's ability to orchestrate humanist flexibility and systemic firmness adapted to local wisdom.
