Abstract

This study aims to develop a circular economy model to promote the sustainability of Integrated Pest Management (IPM)-based rice farming in Kediri Regency, Indonesia. Agricultural systems in the region face persistent challenges, including environmental degradation and chemical overuse. By adopting key principles of the circular economy—such as reduce and recycle—this research offers a practical solution to optimize resources and minimize ecological impact in rice farming systems. A mixed-methods approach was employed, combining sustainability assessment tools and structural equation modeling to evaluate and validate the model. Data were collected from 100 purposively selected IPM-oriented farmer groups. The results indicate that the "reduce" (β = 0.642) and "recycle" (β = 0.510) principles have the strongest influence, supported by high adoption rates (83% and 76%, respectively), while the "reuse" principle shows the lowest impact (β = 0.206), hindered by institutional and infrastructural limitations. The model demonstrates adequate reliability and convergent validity, confirming its applicability for sustainable farming evaluation. Overall, this study concludes that integrating circular economy strategies within IPM-based rice farming provides a viable pathway for ecological sustainability and offers an educational framework to foster environmental literacy. Strategic policy support and educational interventions are essential to scale up these practices across agricultural systems.

Abstract

Population growth and urban activities have caused land conversion and decreased environmental carrying capacity. The existence of Green Open Space (GOS) is crucial in improving environmental quality and increasing community welfare. In Ngantru Urban Area, data collection on private GOS is still incomplete, although this is important to increase the Land Quality Index in Tulungagung Regency. Using the Supervised Land Classification method allows for more accurate identification and mapping of private GOS potential through remote sensing data analysis. Based on the results of the analysis, private GOS in Ngantru Urban Area consists of agricultural land covering an area of 1,694.35 hectares. Padangan Sub-district has the largest area, namely 321.04 hectares or 18.95% of the total area of private GOS, followed by Pojok Sub-district with 287.09 hectares or 16.94%. The difference in the area of private GOS between Sub-districts reflects the diverse development potential in each region. This data is an important basis for formulating more effective and sustainable spatial planning policies, as well as supporting targeted environmental conservation efforts to improve the quality of life of the community.
