Abstract
The leather tanning industry in Ringinagung Village, Magetan District, Magetan Regency, East Java, is one of the largest people's leather-industry centres in East Java, having developed over several decades and become a backbone of the local economy by creating employment and strengthening the small and medium leather- based industry sector. At the same time, the tanning process, which uses large volumes of water and chemicals such as chromium, lime, and other organic compounds, has the potential to generate liquid waste, solid waste, and gas emissions that can degrade environmental quality and give rise to complaints among the surrounding community. Prior studies have generally examined the impacts of the leather industry only partially, focusing either on the production process (life cycle assessment), circular-economy policy, or socio-economic impacts, without integrating multiple impact dimensions at once. This study addresses that gap by comprehensively and simultaneously analysing five impact dimensions, namely physical-environmental, social, economic, public-health, and land-value impacts, while also identifying the environmental factors that cause those impacts and formulating relevant mitigation measures. The study employed a mixed-methods approach with an explanatory sequential design, beginning with a quantitative phase consisting of environmental-quality measurements (water, air, and soil), a questionnaire survey of the community around the 31 leather-industry sites that constituted the study population, and land-value analysis based on distance-based zoning from the centre of the industrial area, followed by a qualitative phase of in-depth interviews with local government officials, industry operators, and community members to explain the quantitative findings. Data were analysed using the Wilcoxon Signed-Rank Test to examine the significance of the impacts, together with multiple linear regression on 27 environmental variables to identify the factors influencing each impact dimension. The results show that the presence of the Ringinagung leather-industry area produced statistically significant impacts across all 14 impact indicators tested (p = 0.000 < 0.05). Within the physical dimension, the most critical impact was on air quality/odour, with measured NMHC concentrations far exceeding the quality standard (989 μg/m3 against a standard of 160 μg/m3) and a spread reaching a radius of 500 metres, while around 15–25% of industry sites were found to be inconsistent with the local Detailed Spatial Plan (RDTR). Within the social dimension, residential comfort was the most affected indicator, impacting approximately 3,393 people within a 0–600 metre radius of the industrial area. The economic dimension displayed a two-sided pattern: the industry is the largest source of employment for the village and surrounding areas, yet it also drove up household living costs, particularly for clean water and health care. Within the public-health dimension, respiratory complaints/ARI were the most dominant issue, reported by 74.2% of respondents, and were correlated with the elevated NMHC levels. Meanwhile, land-value impacts showed a dual pattern, with commercial land values along the main road rising due to industrial agglomeration effects, while residential land values within a close radius of the industry were suppressed by negative environmental externalities. Regression analysis showed that the combined environmental factor significantly influenced economic impact (R2 = 0.220; p = 0.008), while at the level of individual variables, the communal wastewater treatment system (IPAL) proved to be the most consistent and significant mitigating factor, whereas business scale, production volume, chemical-use intensity, and proximity to settlements were significant driving factors of impact. Mitigation efforts already undertaken, such as the operation of communal wastewater treatment facilities, the installation of geomembranes for hazardous waste storage, the development of greenbelts, and periodic health check-ups for workers, were found to be reasonably effective for managing liquid waste, but remained weak in addressing air-quality impacts and soil degradation, and were further constrained by limited government supervisory capacity and uneven compliance among small- and micro-scale industry units. This study offers novelty through the simultaneous integration of five impact dimensions within a single industrial-area analytical framework, the incorporation of a distance-based land-value zoning variable linked to environmental quality and community risk perception, and evidence-based policy recommendations for local government, industry operators, and the community to support more sustainable environmental management and spatial planning in people's leather-industry areas. Keywords: environmental impact, land value, leather industry, mixed methods, Ringinagung
