Penggunaan metode kuantitatif cukup berkembang pada tahun 1950an dalam bidang sedimentologi dan stratigrafi terutama dalam membantu menjelaskan asosiasi fasies, proses pembentukannya dan lingkungan pengendapan. Lokasi penelitian berada koordinat 07° 30' 00,0" – 07° 30’ 30.0” LS dan 109° 27' 30,0" – 109° 28’ 10,0” BT yang secara administratif berada pada Provinsi Jawa Tengah. Daerah penelitian termasuk ke dalam Formasi Halang. Tujuan dari penelitian ini adalah untuk mengetahui model asosiasi fasies lokal yang terbentuk pada daerah penelitian. Pengambilan data dilakukan dengan metode penampang stratigrafi terukur pada sebagian lintasan Sungai Kaligintung sedangkan pengolahan data dibantu oleh metode kuantitatif berupa analisis Markov Chain dan Binomial Probability untuk mengetahui hubungan antar fasies.

Sixteen samplesediments was carried out from 140 meter section in Jragung River with 10 meter interval.Species and specimen of small benthic foraminifera was quantified in every 1 (one) gramdry sample sediment. Cluster analyses of small benthic foraminifera assemblages showedthat research area is comprises of 4 (four) biofacies. There are Biofacies A-JR (deep seawith middle bathyal zone), biofacies B-JR (shallow sea with outer shelf zone), biofacies C-JR (deep sea with middle bathyal – abyssal zone) and biofacies D-JR (deep sea withmiddle bathyal – lower bathyal zone).

Administratively, the research areas included in the district of Semarang, Central Java Province. This research was conducted at Jeragung River with the object of claystone and sandstone. In physiographic, rocks in the study area are in Kendeng Basin, and parts of Anggota Banyak Kalibeng Formation. This study aims to determine the characteristics of sedimentary rocks mainly sandstones, based on petrographic analysis to determine the source of the sediment and diagenesis processes that formed. Based on observations of six sandstone samples from areas of research included in Feldspatic Wacke. Provenance analysis of six samples of sandstone with using Dickinson and Suczek triangles, shows the origin of sediment is arc magmatic. Diagenesis phase which occurs is eogenesis characterized by compacting and leaching, mesogenesis marked by cementation and recrystallization, as well as the replacement and deformation marks telogenesis process.

The research area is located in the Juwangi, Grobogan District, Central Java Province. Geographically located between 110o 44’ 19,536” BT – 110o 49’ 19,5384” BT dan 7o 13’ 53,2704” LS – 7o 8’ 53,2716” LS. Research using the method geological surface mapping. Determination of depositional environment unit based on the characteristic of lithology, sedimentary structures, and benthic foraminiferal. Based on the characteristic of lithology, this unit composed of mudstone and sandstone. Mudstone has a consideralable thickness, as sandstones insert. Sedimentary structures that are found in the form of parallel lamination and cross lamination shows that its transport medium is water. Benthic foraminiferal analysis result indicate that the bathymetry zone is outer neritic. So it can be estimated that the depositional environment of this unit are in the shallow marine.

ABSTRACTThis research was conducted to determine environmental changes in the study area based on the abundance of foraminifera fossils and the lithology of the emerging rocks. The research area is in Jatiluhur District, Purwakarta Regency, West Java Province. Rock samples taken during the Advanced Geological Mapping activity were then used as a composite log, divided into 15 rock samples representing any changes in lithological characteristics. The number of small foraminifera fossils found from the 15 samples was 120,912 individuals with 75,840 individual planktonic foraminifera fossils and 45,072 individual benthonic foraminifera fossils. The abundance of small foraminifera fossils varies in number in each sample and the number is more abundant in the younger layers than in the older layers. The P / B ratio analysis was performed using a comparison calculation between planktonic and benthonic foraminifera. From the P / B ratio analysis, it was found that four bathymetric zones had occurred in the study area. From the results of the P / B ratio analysis and associated with rock lithology, it can be concluded that the environment of the study area is in a shallow sea where there have been several times of local deepening and silting of the water column. The analysis of environmental changes is strengthened by drawing the age which is determined based on the appearance of the fossil index in the layers. Referring to Bolli & Saunders (1985) and Boudagherfadel & Banner (1999), the results of this analysis indicate that the study area was deposited at an age not older than the Middle Miocene.Keywords: Foraminifera, Abundance, Environment, Lithology, Middle MioceneABSTRAKPenelitian ini dilakukan untuk mengetahui perubahan lingkungan pada daerah penelitian berdasarkan kelimpahan fosil foraminifera dan litologi batuan yang muncul. Daerah penelitian berada pada Kecamatan Jatiluhur, Kabupaten Purwakarta, Provinsi Jawa Barat. Sampel berupa batuan yang diambil ketika kegiatan Pemetaan Geologi Lanjut yang kemudian dijadikan sebuat composite log terbagi menjadi 15 perconto batuan mewakili setiap perubahan karakteristik litologi. Jumlah fosil foraminifera kecil yang ditemukan dari 15 sampel tersebut adalah 120.912 individu dengan fosil foraminifera planktonik 75.840 individu dan foraminifera bentonik 45.072 individu. Kelimpahan fosil foraminifera kecil bervariasi jumlahnya pada masing-masing sampel dan jumlah tersebut lebih melimpah pada lapisan yang lebih muda dibandingkan dengan lapisan yang lebih tua. Analisis P/B ratio dilakukan menggunakan perhitungan perbandingan antara foraminifera planktonik dan bentonik. Dari hasil analisis P/B ratio didapatkan empat zona batimetri pernah terjadi pada daerah penelitian. Dari hasil analisis P/B ratio dan dikaitkan dengan litologi batuan, dapat ditarik kesimpulan bahwa lingkungan dari daerah penelitian berada pada laut dangkal dimana terjadi beberapa kali pendalaman serta pendangkalan kolom air secara setempat. Analisis perubahan lingkungan diperkuat dengan penarikan umur yang ditentukan berdasarkan kemunculan indeks fosil pada lapisan. Mengacu pada Bolli & Saunders (1985) dan Boudagherfadel & Banner (1999), hasil analisis tersebut menunjukkan bahwa daerah penelitian diendapkan pada umur tidak lebih tua dari Miosen Tengah.Kata Kunci : Foraminifera, Kelimpahan, Lingkungan, Litologi batuan, Miosen Tengah.
