APPLICATION OF DEACIDIFICATION FOR ARCHIVES CONSERVATION AT THE SINGOSARI NATIONAL ARTIFICIAL INSEMINATION CENTER (BALAI BESAR INSEMINASI BUATAN, BBIB), INDONESIA

Archives are generally printed on paper. The paper constituting the archives can be affected by internal and external factors and over a long period of time, can easily decay and yellow stain spots can appear. Factors such as temperature, humidity, and the acidity level of the paper, will influence the physical strength of the paper. In order to save the valuable information in the archives, it is therefore essential to take action to preserve the physical paper. One of the internal factors that can cause deterioration and decoloration, especially for paper, is the acidity generated during its natural ageing.
