Abstract

This community engagement program aimed to address the environmental problem of untreated liquid waste generated by household-scale tempeh production in Plaosan Village. Using a participatory action research approach, the program facilitated collaborative learning, hands-on fermentation training, and reflective planning with 35 tempeh-producing households. The intervention focused on transforming nutrient-rich soybean wastewater into a usable liquid organic fertilizer (LOF) using EM4 technology and local materials. The results indicated significant improvements in environmental knowledge, fermentation skills, and behavioral change: post-test knowledge scores increased by 44.5%, and 77% of participants reduced direct waste discharge. Moreover, three women emerged as peer educators, leading micro-replication efforts. This initiative demonstrated that dialogical, experiential learning can successfully promote sustainable waste management practices, empower local actors, and catalyze grassroots environmental stewardship.

Abstract

This study examines how digital automation and data-driven decisions influence operational performance and service reliability through lean operations culture in Chinese-owned digital retail firms. A quantitative approach was applied using survey data collected from managers and supervisors responsible for operations and information systems. Structural equation modeling was employed to test the proposed relationships among the constructs. The results indicate that digital automation significantly strengthens lean operations culture, while data-driven decisions also show a positive and meaningful effect on the same mediator. Lean operations culture demonstrates a strong influence on both operational performance and service reliability, confirming its central role in translating technological resources into operational outcomes. These findings highlight that technology adoption alone is insufficient without a supporting cultural orientation toward waste reduction, continuous improvement, and disciplined execution. The study contributes to operations management literature by integrating technological and cultural perspectives within a single explanatory framework. From a managerial standpoint, the results suggest that leaders in Chinese-owned digital retail firms should align automation investments with data-based routines and lean values to achieve sustainable performance improvements and reliable service delivery globally.
