Abstract

Formasi Jatiluhur di sekitar Sungai Cileungsi merupakan lingkungan laut dangkal (zona neritik) berdasarkan dominasi foraminifera yang dikandungnya. Namun beberapa penelitian terdahulu menyatakan umur Formasi Jatiluhur yang bervariasi. Penelitian paleobatimetri berdasarkan kumpulan foraminifera kecil diharapkan dapat melengkapi kajian detil yang terkait dengan evolusi daerah ini selama Miosen. Pengambilan 30 sampel sedimen dilakukan secara sistematik pada satu lintasan di sepanjang Sungai Cileungsi. Hasil preparasi sampel sedimen dengan metode hidrogen peroksida menghasilkan 57301 individu foraminifera kecil yang terdiri dari 23276 individu foraminifera plangtonik dan 34025 foraminifera bentonik. Untuk mengetahui paleobatimetri, digunakan rasio foraminifera plangtonik dan foraminifera bentonik kecil.  Hasil  Rasio P/B berkisar antara 4,4 % - 74,0 % menunjukkan paleobatimetri Formasi Jatiluhur berkisar antara zona neritik dalam – zona batial atas.Jatiluhur Formation in the area of Cileungsi River was a shallow marine environment based on the foraminiferas domination. Several previous published papers had suggested age variation of the Jatiluhur Formation. Paleobatimetry study based on small foraminiferas was expected to complete the Miocene evolution analysis of the region. Thirty sediment samples were picked systematically in a section line along Cileungsi River. The hydrogen peroxide preparation of sediment samples produced 57301 small foraminifera. There were 23276 planktonic foraminiferas and 34025 benthic foraminiferas.  To understand the paleobathimetry of this research area, we calculated the ratio of planktonic foraminifera and benthic foraminifera (P/B ratio).  The P/B ratio is betweeen 4,4% and 74,0%.  The ratio suggests that the paleobathimetry of Jatiluhur Formation is Inner Neritic Zone - Upper Bathyal Zone.

Abstract

Daerah penelitian merupakan bagian dari Laut Jawa terletak di Perairan Jawa Tengah bagian Utara. Laut Jawa dibatasi oleh tiga pulau besar sehingga kondisi Laut Jawa menjadi tertekan karena memperoleh kontribusi air dan sedimen dari ketiga pulau tersebut. Tujuan dari penelitian ini adalah untuk menentukan biofasies dan kondisi ekologi dari daerah penelitian berdasarkan kumpulan foraminifera bentik kecil. Foraminifera bentik kecil adalah hewan laut uniseluler bercangkang yang hidup di atas atau di dalam sedimen dasar laut. Kehidupannya sangat dipengaruhi oleh lingkungan sehingga foraminifera dapat digunakan sebagai indikator lingkungan. Analisis kuantitatif dilakukan pada 32 sampel sedimen dengan cara mengumpulkan data foraminifera bentik kecil berukuran 0,125 mm pada setiap satu gram sampel sedimen kering. Berdasarkan analisis kluster, daerah penelitian terbagi menjadi 4 biofasies yaitu Biofasies I (Zona Litoral-Zona Paparan dalam), Biofasies IIa (Zona Paparan dalam), Biofasies IIb (Zona Litoral-Zona Paparan dalam) dan Biofasies III (Zona Paparan dalam). Selanjutnya, nilai indeks diversitas dari keempat biofasies tersebut berkisar antara 0,7 – 1,1. Keempat biofasies dan nilai indeks diversitas menunjukkan daerah penelitian merupakan lingkungan laut dangkal dengan tekanan ekologis sedang sampai tinggi.Kata Kunci: foraminifera bentik kecil, biofasies, indeks diversitas, laut dangkal, ekologi, Perairan Jawa Tengah bagian Utara. The research area is part of the Java Sea located in the northern part of Central Java. Java Sea is surrounded by three large islands. Therefore, its condition becomes depressed because of the contribution of water and the sediment from the three islands. The purpose of the study is to determine the biofacies and ecological conditions of the research area based on small benthic foraminifera assemblages. The small benthic foraminifera are unicellular sea shell animals that live on or within the sediment of the seabed. Its life is severely influenced by the environment so that the foraminifera can be used as environmental indicators. Quantitative analysis was carried out on 32 sedimentary samples by collecting of 0.125 mm benthic foraminifera on each one gram of dried samples. Based on the cluster analysis, the research area is divided into 4 biofacies i.e. Biofacies I (Littoral Zone-Inner Shelf Zone), Biofasies IIa (Inner Shelf Zone), Biofacies IIb (Littoral Zone-Inner Shelf Zone) and Biofacies III (Inner Shelf Zone). Furthermore, the range diversity index value of all biofacies is 0. 7 – 1.1. It can be concluded that the all biofacies and diversity index value shows the research area is shallow sea with medium stress to highly stress ecology.Key words: small benthic foraminifera, biofacies, diversity index, shallow sea, ecology, northern Central Jawa waters

Abstract

Arafura Sea is influenced by several climatic dynamics, it is also a part of the coral triangle that provides most of marine organism diversity of the world. Therefore, this area is an important  waters that impact the climatic dynamic so its paleoceanographic changes need to be understood. For that, we analyzed the foraminiferal PB ratio from marine sediment core ARAFURA-24 with a core length of 179 cm, collected from 47.4 m water depth, combined with that of Aru-07, taken from 276 m water depth (core length 152 cm). Both sediment cores were collected from the Arafura Sea using a gravity corer on board Geomarin III. ARAFURA-24 was sub-sampling in every 20 cm interval, while Aru-07 had been prepared in every 10 cm interval. PB Ratio values from ARAFURA-24 and Aru-07 ranged from 0,56% - 7,43% and from 29,89% to 82,66%, respectively. The age model was reconstructed by 14C radiocarbon dating derived from organic sediment, combined with tie points of PB ratio records. The result indicates that ARAFURA-24 has been sedimented since the last 9.7 kyr BP. PB ratio records reveal three maximum sea level rises, which are before 7.4 kyr BP, at 5.86 kyr, and after 3 kyr BP (approximately at 2 kyr BP at Aru-07). From the age model reconstruction, sedimentation during the last 3 kyr BP was relatively slower than that in the older period. It can be concluded that the foraminiferal PB ratio during Late Holocene was not significantly impacted by sedimentation rate (hence detrital influence), in contrast, during Mid-Holocene detrital influence had more impact on the PB ratio record.

Abstract

AbstractRecent measuring stratigraphic observation in Cikandung River has revealed the Late Pliocene stratigraphic and tectonic event. Research area is located in easter Bogor Trough. Previously, it was stated controversially pertaining to the stratigraphic relationship between Kaliwangu and Citalang Formations. The outcrop-based remark has never been explained, slightly intuitive. Making strike and dip measurements and stratigraphic analysis using tape and compass traverse were done to unveil the role of Plio-Pleistocene tectonic regime in stratigraphic-filling of the basin. Strike azimuths recorded from several locations of Citalang and Kaliwangu Formations show angular geometry and both of those sedimentary facies within formations indicate the significant and rapid change in depositional process. But interestingly, the angular geometry is only founded in the southern part of study area. To the north, angular relationship becomes parallel. This geometrical distribution implies the strong influence of tectonic regime in Late Pliocene interval. The evidence from outcrops observation conclude the unconformity between Citalang and Kaliwangu Formations. Keywords: Stratigraphic unconformity, Citalang and Kaliwangu Formations, Plio Pleistocene Tectonic
