The Progo River starts from the highlands of Temanggung and Magelang regencies in Central Java, then to the southeast towards Sleman, Bantul and Kulonprogo regencies in Yogyakarta. The Progo River empties into the west of Kwaru Beach on the southern coast of Java.

In Ngluwar district, Magelang regency, this river was dammed into two streams for irrigation for agriculture in Yogyakarta by Dutch colonial. The dam is known as "Ancol Bligo" which is now a place for recreational residents.

This irrigation flows from Ngluwar to the east to divide Sleman regency and to Klaten regency, known as Selokan Mataram or "Van Der Wijck Gutter", while the other flows in Kulonprogo regency along the Menoreh Mountains valley.

The oldest drawing specimen collection, Balaenoptera physalus Linnaeus, 1758 (OBS.296787995)

BLOG - Before the invention of photography, everything was explained by hand drawings that required naturalists to be able to draw to describe the specimens they documented. Scholars from taxonomy to medicine had to be able to sketch leaves to the human heart, this is why the academic world at that time had the subject of "art and science". A tradition that taxonomic drawings are accompanied by a measurement scale usually by placing a measuring tool in millimeters or centimeters or inches that supports scientific sketches has an identification context, but of course there are obstacles to having to document large specimens. I found a picture of a large specimen: Balaenoptera physalus (Linnaeus, 1758). Uniquely, the specimen with catalogue number: OBS.296787995 and stored at the Observation International, Aarlanderveen, Netherlands, is the oldest I have ever known. The shabby drawing with three folds and worn edges was made in 1547 or more than 500 years old. Previously I ...
