Abstract

Public perception of the need for batik has declined since the COVID-19 pandemic. It significantly reduced the quantity of batik sales and production, with many industries ceased production. Therefore, relevant strategies integrating technology and culture were needed to maintain the resilience and sustainability of batik businesses. This paper presents the techno-culture view of three aspects of the batik industry: the production process, marketing, and management of batik wastewater. To capture the current conditions, field surveys using qualitative methods in questionnaires and interviews with batik respondents were carried out twice in Trusmi, Cirebon, during and after the COVID-19 pandemic. The survey results were presented, comparing wastewater characteristics during and after the pandemic to determine whether there were significant differences in the wastewater management process between the two periods. The priority of wastewater management strategy was analyzed using the Analytical Hierarchical Process, and it was found that the main priority was the environment (0.58), followed by social (0.23), economy (0.15), and institution (0.05). In addition, the Water Quality Index in the sample has a value range of 47 (Class III/Fair) to 69 (Class IV/Poor/Marginal).
