JAKARTA, Indonesia — The death of an Indonesian copywriter has generated a surge of anger in Indonesia, turning the young woman into an inadvertent symbol of the grueling, workaholic culture of the advertising world.

Shortly after working a 30-hour shift, Ananda Pradnya Paramita, 27, a copywriter for Young & Rubicam Indonesia, fell into a coma on Saturday at a South Jakarta pizzeria.

Ms. Paramita, who referred to herself as Mita Diran on social networks, was taken to a hospital, but died the following day.

Her revealing final post on Twitter, “30 hours of working and still going strong,” has prompted accusations that her agency pushed her over the edge with its work demands.
