Abstract

Access to clean water remains a challenge for residents of Karangluas Village, Kemiri District, Purworejo Regency, Central Java, Indonesia. Water from wells and communal storage tanks still contains suspended particles and fine sediments, making it appear turbid and less suitable for household use. This community service project aimed to apply a simple water filtration system using locally available materials through a combination of zeolite, coconut coir, and aquadine media. The program was conducted from August to September 2025 and involved 25 local participants in a training and hands-on workshop held at the Karangluas Village Hall. Laboratory analysis indicated that the filtration system reduced total dissolved solids (TDS) by 16.7%, iron (Fe) by more than 50%, and Escherichia coli bacteria by 35.3%. Although turbidity and manganese (Mn) levels were below the instrument’s quantification limit (<2.86 NTU), the filtered water met most parameters of the national clean water quality standards (Minister of Health Regulation No. 2 of 2023). Socially, the program increased public awareness of household water treatment and encouraged community members to replicate and maintain the filtration units independently. These results highlight the potential of locally based filtration technology to improve water quality, public health, and the sustainability of community-level water management.

Abstract

Grounded in the Resource-Based View and Dynamic Capabilities Theory, this study examines how internal and relational capabilities shape competitive advantage among small and medium-sized enterprises (SMEs) in the service sector. The research investigates the influence of innovation capability and absorptive capacity on competitive advantage, with collaborative networks tested as a mediating variable. Previous studies have reported inconsistent results regarding these relationships, particularly within resource-constrained SME contexts. To address this gap, data were collected from 113 SME owners and managers in the laundry service industry using a structured questionnaire with a five-point Likert scale. Data were analyzed using Partial Least Squares-Structural Equation Modeling (PLS-SEM) with SmartPLS to assess both the measurement and structural models. The findings reveal that innovation capability (β = 0.456, p < 0.001) and absorptive capacity (β = 0.439, p < 0.001) significantly enhance competitive advantage. Both variables also positively influence collaborative networks, which in turn have a significant effect on competitive advantage (β = 0.286, p = 0.001). Moreover, collaborative networks partially mediated the relationship between absorptive capacity and competitive advantage (β = 0.109, p = 0.048), but not between innovation capability and competitive advantage (β = 0.141, p = 0.062). These findings confirm that innovation and knowledge absorption are strategic resources that drive competitiveness, while collaboration provides conditional benefits depending on firm capabilities. Managers are encouraged to institutionalize regular customer feedback systems and strengthen partnerships with local suppliers to enhance innovation outcomes. The study clarifies inconsistencies in prior research and provides practical insights for improving SME competitiveness through balanced internal and external capability development.
