Under Adinegoro’s leadership, Pewarta Deli had many improvement and changes, not only in terms of layout and news reporting, but also in the choice of articles. The attention of all Pewarta Deli’s readers was aimed at the brilliance of Adinegoro’s writings. Uniquely, his articles about the war in Abyssinia and the civil war in Spain were attached on a map that showed the location of the war, making it easier for readers to understand the reports. During that time attaching pictures or maps in a local media was uncommon.
