Abstract

Road development has been a primary focus in efforts to enhance connectivity and mobility across various regions, especially in densely populated urban areas that often serve as economic hubs. While crucial for addressing mobility challenges in urban settings, it is essential to acknowledge that road development in rural areas also holds significant importance. This paper investigates the sustainability of rural road development through five dimensions of environmental, social, economic, institutional management, and law enforcement, a case study on Woro Village, Kepohbaru District, Bojonegoro Region. The quantitative research collected data through a questionnaire from 84 respondents who are members of the village community. The data analysis employed Multidimensional Scaling (MDS) using R-studio software. The result is indicated by the sustainability index of the environmental index of 83.93; the social index of 86.46; the economic index of 88.06; the institutional management index of 79.32 and the law enforcement index of 86.15. The research findings indicate rural road development has demonstrated good sustainability in various aspects, including environmental, social, economic, management institutions, and law enforcement. This confirms that efforts to build rural roads have provided sustainable and diverse positive impacts on local communities and the surrounding environment.

Abstract

City rivers in rapidly expanding tropical regions face considerable degradation due to domestic wastewater and urban runoff. Our study uses the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) and Principal Component Analysis (PCA) to assess water quality in the Gembong River, Pasuruan City. It introduces a new integrative approach by combining the CCME-WQI and PCA to simultaneously assess overall water quality status and identify key pollution-causing parameters along with their seasonal variability, addressing the limitations of previous studies that applied these methods separately without linking pollution sources to temporal dynamics. Sampling was conducted at five stations during the rainy, transitional, and dry seasons. Results showed that all stations fell into the Poor category (WQI 37.71–45.67), with Station 2 exhibiting the lowest quality due to dense settlements and untreated drainage discharge. Seasonal analysis revealed significant variations in fecal coliforms, which peaked during the rainy season due to runoff. PCA identified BOD, COD, and fecal coliform as dominant domestic‑wastewater indicators, while TSS and phosphate reflected land‑use effects. A weak negative correlation between rainfall and BOD–COD suggests continuous wastewater input is the primary driver of pollution. These findings imply that pollution control strategies should prioritize the reduction of BOD, COD, and fecal coliform through improved domestic wastewater treatment systems, particularly in densely populated areas, while TSS and phosphate management should focus on controlling surface runoff and land use practices. These results provide a scientific basis for targeted pollution control and adaptive urban water management strategies to support sustainable river governance.
