KRENOVA JATENG 2023: Teknologi Tepat Guna Alat Filtrasi Limbah Batik Kutawaru Cilacap_FlyAsh

Summary

Cilacap, the largest regency in Central Java, has significant potential for national-scale activities, including industries like power plants and batik production. The region's batik industry faces challenges with waste management, especially in the form of harmful wastewater. This script introduces an innovative solution to process batik wastewater using activated fly ash, a byproduct from power plants. The method successfully reduces pollution levels, offering a sustainable alternative for batik businesses. The goal is to reduce environmental impact and provide a practical, environmentally friendly solution for wastewater treatment in Cilacap's batik industry.

Takeaways

• 😀 Cilacap is the largest district in Central Java, Indonesia, and has significant industrial activity.
• 😀 The district's industries include coal-fired power plants (PLTU) and home batik production, which contribute to pollution.
• 😀 Batik wastewater, especially from Kutawaru, contains harmful dyes (both natural and synthetic) that can pollute local water sources.
• 😀 Untreated industrial waste, especially batik wastewater, can lead to serious environmental and health problems, including skin diseases and cancer.
• 😀 Coal-fired power plants release fly ash, which contains heavy metals that can pollute the environment if not properly managed.
• 😀 Batik wastewater, especially in Kutawaru, is currently treated using conventional methods, but there is room for more efficient solutions.
• 😀 The innovation presented is a filtration system using green sand, gravel, and clay activated with sulfuric acid to treat industrial wastewater.
• 😀 The aim of the innovation is to reduce water pollution from batik wastewater and fly ash in Cilacap and provide a sustainable solution for the industries.
• 😀 Initial lab results show a significant reduction in pollutants such as BOD (90% decrease), COD, and Total Suspended Solids after applying the filtration system.
• 😀 This technology not only helps reduce environmental pollution but also provides a cost-effective and eco-friendly solution for batik producers in Cilacap.
