The Research area is located on waters of Jepara, Central java. The sediment samples for this research were taken from core sample A with 65 cm lengths at coordinate of S 05°55’18.66” and E110°42’34.55”. There are 12 sediment samples used for this research with 5 cm of length interval for each sample. The objective of this research is to find out the environmental conditions around waters of Jepara based on the diversity index. Hydrogen peroxide method is used to process the sediment sample that contain foraminifera. Quantitative analysis of foraminifera was performed on 1gram dry sample. Results of Shannon-Wienner index to find the diversity ranges from 0.00282 to 0.01138. That result shows a low diversity index, it can be concluded that the conditions of the marine environment around waters of Jepara in the Core A has a low productivity, high ecological pressure, and has a disturbed ecosystem.
