BRIN researcher, Kustini, stated that several mosques in Indonesia have contributed to environmentally friendly practices, such as Isqtiqlal Mosque in Jakarta. This mosque has implemented low-flow water taps and a water recycling system, successfully reducing water usage by up to 36%. Additionally, Istiqlal Mosque received the Excellence in Design for Green Efficiencies (EDGE) award and become the first mosque in the world to be recognized as an environmentally friendly house of worship. Another example is Jami’ Al Ilham Mosque in Pati, which collects rainwater for irrigating nearby fields, while the Al Akbar National Mosque in Surabaya uses 24 solar panels to generate around 40 kWh of electricity per day.
The Directorate General of Islamic Guidance Decree No. 463 of 2024 also emphasizes the importance of environmentally friendly mosques, covering aspects of management (idarah), mosque welfare (imarah), and maintenance (riayah). These mosques adopt waste management policies, energy-saving measures, and digitalization to reduce paper usage. With 660,290 mosques in Indonesia in 2023, this vast potential can be utilized to create a safe and comfortable environment.
