Pontianak Carbide Cannon Festival in Pontianak
Meriam karbit, cannons made from hollowed logs filled with calcium carbide, produce loud percussive explosions along Pontianak's Kapuas riverbank, a sound-based tradition legend dates to 1771 under Sultan Syarif Abdurrahman Alkadrie. Historically signaling Maghrib prayer and the breaking of the Ramadan fast, the tradition now spans Eid al-Fitr and Eid al-Adha, with a recent edition recording forty-two firing locations and two hundred twenty-nine participating cannons.
