SIYASIG: The Southern Luzon Journal of Science is the refereed, open-access research journal for the pure and applied sciences published annually by the Southern Luzon State University in the Philippines. The journal was approved as an institutional journal of the University by virtue of BOR Resolution No. 52, series of 2022.

The journal aims to disseminate cutting-edge scientific and technological knowledge that may have particular implications for the Southern Tagalog region. It also seeks contributions from researchers in fields such as, but not limited to, natural sciences, agriculture, medical sciences, engineering, and technology. Submissions from interested researchers not affiliated with SLSU on the aforementioned topics are welcome. 

The term SIYASIG was coined from the two Filipino words blended together, “siyasat” or vigilant inquiry and “sigasig” or persistence. Thus, the title embodies the essence of assiduous investigations of variables necessary for significant explorations and research activities.
