Investigation of Sick Building Syndrome (SBS) Through Student Perceptions of the Indoor Environmental Quality (IEQ) of School Building Near the Airport
Full text linkSchool buildings that use natural ventilation have challenges to Sick Building Syndrome (SBS) due to high noise intensity and the need to circulate air by opening windows. This study investigated SBS symptoms in schools closest to the airplane runway. Subjective measurements were carried out using self-administrative questionnaires to determine students’ perceptions. Objective measurements to obtain Indoor Environmental Quality (IEQ) data were carried out through an experiment of opening a window with an awning window type as far as 11 cm or 1/2 of the window span with an angle of 12.5. The average results of IEQ measurements on the thermal aspect include a temperature of 30.1 C, CO2 levels of 331 ppm, and wind speeds of 0.1-0.3 m/s have met the minimum comfort standards. However, the average humidity in the classroom has not been met. In addition, classroom noise is still far from the comfort standard, which is 70-109 dB. However, the results of the evaluation of students’ perception assessments of the IEQ of the room showed no symptoms of SBS in terms of physical and psychological aspects. Most students were not disturbed by the less-than-ideal thermal and acoustic conditions. However, students can experience long-term health problems and potentially experience psychological stress if they are continuously exposed to high levels of noise and less-than-ideal IEQ conditions
The Dynamics of Determinants Making Stock Investment Decisions: Does Investor Sentiment Possess Significant Influence?
Full text linkIn 2024, the Composite Stock Price Index underwent a significant fall due to multiple domestic and worldwide issues. Numerous prior research have investigated financial behavioral elements as a connection in investment decisions; nevertheless, this study presents originality by concentrating on these factors that exert a direct influence. This study analyzes the financial behavioral aspects that affect stock investment decisions in Indonesia, particularly in the Jakarta region. This research employs a quantitative approach via a questionnaire survey to gather primary data, which is subsequently analyzed using SmartPLS. This discovery alters the current paradigm. This study revealed that, despite the common belief that investor sentiment affects investing decisions, the findings indicate that investor sentiment does not exert a substantial influence. This study demonstrated that, contrary to numerous other studies indicating that investor sentiment affects investment decisions, investor sentiment does not exert a substantial influence. This discovery contests the current paradigm and demonstrates that elements such as economic fundamentals, market volatility, and individual investor traits are more influential in investment decision-making. This study encourages research on other factors affecting Indonesian stock market investment decisions. Future research should include more factors and widen the study region to better understand investment behavior
Corporate Risk as a Mediator in Banking Financial Performance: Examining the Impacts of Sustainable Finance, Governance, and Auditor Reputation
Full text linkThis study investigates the role of corporate risk as a mediator in the relationship between sustainable finance, governance mechanisms, and auditor reputation on banking financial performance. With the increasing emphasis on sustainable finance, particularly following regulations like POJK No.51/POJK.03/2017, the integration of economic, social, and environmental factors in financial reporting has gained prominence. The research employs a quantitative methodology using SMARTPLS version 4.0 and SEM-PLS analysis, focusing on data from banking institutions listed on the Indonesia Stock Exchange from 2021 to 2023. The findings reveal that auditor reputation significantly enhances financial performance, while corporate risk negatively impacts it. Sustainable finance shows a positive but insignificant effect, and governance mechanisms do not significantly influence financial performance. Notably, corporate risk significantly mediates the relationship between sustainable finance and financial performance, indicating that effective risk management is crucial for leveraging sustainable finance initiatives. This study contributes to the understanding of how corporate governance and sustainable practices can enhance financial stability in the banking secto
Urban Street Food Buying Decision Toward Eco-Friendly Packaging: The Mediating Effects of Perceived Healthiness and Perceived Naturalness
No full textThis study aims to examine the influence of Green Packaging (GP), Environmental Awareness (EA), and Willingness to Pay (WTP) on Purchase Decision (PD), with Perceived Naturalness (PN) and Perceived Healthiness (PH) serving as mediating variables among street food consumers in urban settings. The research methodology employs a quantitative approach via a survey technique. The sample comprised 161 street food patrons chosen through a purposive sampling method. The investigation was conducted utilizing the Partial Least Squares-Structural Equation Modeling (PLS-SEM) technique. The findings indicated that GP exerted no significant influence on the purchase choice, whereas EA and WTP demonstrated a positive and significant impact on BD when assessed directly. The association between green packaging mediated by perceived naturalness is favorable and substantial, however it is not significant when mediated by perceived healthiness. Environmental awareness shows a substantial and favorable correlation with BD, either directly or through mediation by PN and PH. The willingness to pay exerts a positive and substantial influence on BD; however, when mediated by PN, this effect is not significant, but mediation by PH results in a positive and significant effect

Riding the Waves: Farmer Resilience in Peri-Urban Area of Malang City
Full text linkRapid urbanization in Malang City's peri-urban areas has reduced agricultural land and increased economic pressure on farmers, leading to a decline in active farmers. To cope with these challenges, farmers develop resilience strategies to sustain their livelihoods. However, research on peri-urban farmer resilience remains limited, particularly in linking cultural and economic dimensions to survival strategies. This study analyzes farmer resilience patterns in response to land use changes and urbanization pressures. A qualitative approach was employed, using in-depth interviews and participatory observation with five landowner farmers and one key informant, a village official in Kedungrejo Village, Malang Regency. Findings identify five key resilience strategies: (1) perception of land as sacred ancestral heritage, (2) family solidarity, (3) financial adaptation through productive debt systems, (4) job diversification, and (5) Application of the life philosophy of Nrimo Ing Pandum values. These strategies are linear and flexible, allowing farmers to transition between resilience forms as needed. Theoretically, this study expands agrarian resilience discourse by integrating coping, adaptive, and transformative capacities in a dynamic peri-urban context. Practically, it offers policy recommendations, including incentives for farmland preservation and livelihood diversification programs within the agricultural sector, ensuring social and ecological stability in peri-urban area
