【 摘 要 】

Basically, the use of foraminifera fossils is used in the exploration of energy resources, especially in the field of petroleum, but as we know foraminifera activities can be a study in monitoring the ancient environment. This study aims to compare the ancient environment of limestone in the Wonosari Formation which is composed of layered limestones that show turbidite symptoms with Bulu Formation characterized by plotted limestones. In this study using a stratified sampling method, abundance and diversity calculation of benthonic foraminifera. From the comparison of the two formations shows the response to changes in environmental changes is seen based on the trend of changes in the diversity of benthic foraminifera.
