Cultural Heritage and Environmental Challenges on Conservation Process of Batik: Ground Water and Subsidence in Pekalongan

Batik, a traditional Indonesian textile art, significantly contributes to local employment and national exports. However, its production processes, which involve intensive water use and dyeing techniques, have raised environmental concerns. This study investigates the environmental impacts of batik production in Pekalongan City, focusing on its role in surface water pollution, groundwater exploitation and land subsidence. It aims to propose sustainable solutions that balance the preservation of cultural heritage with environmental protection. Utilizing a multi-faceted approach, this research includes mapping batik production sites and examining data on groundwater extraction and land subsidence. Key findings reveal that batik production significantly contributes to severe surface water pollution through the discharge of untreated wastewater. This pollution exacerbates groundwater reliance, leading to substantial land subsidence. Over 80% of the water used in batik production is sourced from groundwater wells, with extraction rates causing 1-2cm subsidence per year. This subsidence increases vulnerability to flooding and coastal inundation, adversely affecting infrastructure and local communities. The study underscores the need for sustainable water management practices, improved regulatory frameworks to mitigate environmental damage and stakeholder engagement to promote sustainable practices in Pekalongan. Collaborative and innovative solutions are crucial for achieving a sustainable and resilient future for the city.
