In Commemoration of Ozone Day, Lights on Several Buildings and Streets in Central Jakarta Turned Off

"I already knew from previous updates, so I wasn't too surprised when the lights went out," he said.

He noted the dimmer streets gave the night a noticeably different atmosphere compared to usual evenings.

"It certainly feels gloomier. But traffic is still heavy and some parts of the roads remain lit," he explained.

Meanwhile, residents near Sarinah up to the HI Roundabout said they had not seen lighting changes as significant as those along Medan Merdeka Selatan.

"I came from Sarinah, and it's still bright there. But once you get here, you can see several lights off," said Sarodi (30).

60-Minute Blackout
