Abstract—Three recent sediment cores (P2S2, P1S1, and P3S1) about 38.5 cm – 47.5 cm length collected from mangrove and coastal area in Cikadal Beach, Sukabumi, West Java, Indonesia. Cikadal Beach is in the same area of Ciletuh Geopark, commonly be the main geological object study in Indonesia. The purpose of this study is to determine paleoenvironment and paleoecology based on recent benthic foraminifers. The methodology is using cluster analysis; the results are two dendrograms that explain sample association and species association. Sample association divided into 5 biofacies, which are the depositional environment of Biofacies A Transitional – Middle Shelf, Biofacies B Transitional – Middle Shelf, Biofacies C Transitional – Middle Shelf, Biofacies D Transitional – Inner Shelf, and Biofacies E Transitional – Middle Shelf. Whereas, species association divided into 2 dominant species, which are Ammonia spp and Operculina ammonoides from 17 determined recent benthic foraminifers. From this result, the conclusions are the occurrence of environmental changes during the deposition process takes place based on the results of the correlation of the three cores. Based on low index diversity of research area, the existence of ecological changes simultaneously with environmental changes.
