This collection is of great importance as a means of education, research, and the preservation of biodiversity. The ITB Zoological Museum carries out preventive preservation to maintain condition and sustainability, as well as prevent damage to the collection. This activity encompasses the processes of identifying and storing the collection, arranging the placement and labeling of the collection, and periodically maintaining the collection. This research aims to examine the preservation process in the collections at the ITB Zoological Museum in order to protect and maintain information in the collections and speed up the search for information on fauna collections that have been stored in the form of photos and videos on the ITB Zoological website.
