“…However, the sampling station distribution pattern tends to be even, not following the depth trend. The depth at each sampling station did not significantly differ, ranging from 28-34.5 m. This is slightly different from the results of a study by Dewi and Saputro (2013), which states that the depth and type of sediment affect certain distributions of foraminifera which are interrelated with other parameters that affect foraminifera life. This is fathomed that the depth of the sampling location is relatively the same.…”

Abstract. Natsir SM. 2022. The distribution of benthic foraminifera in coral reefs ecosystem of East Penjaliran Island, Seribu Islands, Indonesia. Biodiversitas 23: 3073-3080. East Penjaliran Island is located in the core zone of Seribu Islands Marine National Park and is included in the protected green area. The research shows the close relationship between benthic foraminifera and coral reef. Certain foraminifera has the same environmental requirement to live with coral reefs. Therefore, the study of foraminiferal assemblages is also very important to shed light on the environmental conditions for the growth of coral reefs through calculating the Foraminifera in Reef Assessment and Monitoring Index (FORAM Index/FI). Sampling was conducted in December 2016 around the coral reef ecosystems of East Penjaliran Island, Seribu Islands. A total of 37 species of benthic foraminifera were collected from the island with a diverse abundance. Based on the FI gained values on average of 3.18. It indicates that East Penjaliran Island is classified as an environmental change for coral reefs' growth. The condition was feasible for the growth of coral reefs, but it tends to be an unfavorable environment for their recovery. The benthic foraminifera assemblages can be classified into three major groups based on the Shannon diversity index and FI (i.e., Group A, Group B, and Group C) with their specific characteristics. Group A was characterized by coarse sand sediment and dwelled dominantly by opportunistic foraminifers such as Elphidium advenum, Elphidium crispum, and Flintina bradyana. Groups B and C have very fine sand sediment, but they dwelled by foraminiferal assemblages in different compositions. Group B was dominated by E. crispum and followed by several species of Peneroplis, but Group C dwelled abundantly by E. advenum, E. crispum, Elphidium depressulum and followed by symbiont-bearing foraminifera such as Peneroplis planatus.

“…Sementara itu untuk kedalaman <800 m hanya ditemukan enam spesies dan untuk kedalaman >1000 m ditemukan lima spesies (Tabel 8). Studi oleh Dewi & Saputro (2013) di perairan laut dangkal Teluk Bone, Sulawesi Selatan juga menemukan bahwa kelimpahan foraminifera bentonik hidup paling tinggi tidak terdapat pada stasiun yang terletak paling dalam.…”

“…Kesimpulan yang sama didapatkan di King George Island, Antartika, dimana foraminifera bentonik hidup paling melimpah ditemukan di dalam sedimen berukuran lanau pasiran (Rodriguer dkk., 2010). Dewi & Saputro (2013) mengidentifikasi hal yang berbeda untuk distribusi foraminifera bentonik hidup di laut dangkal Teluk Bone. Mereka mengidentifikasi bahwa kehadiran foraminifera bentonik di Teluk Bone tidak berkaitan dengan jenis sedimen, namun lebih terpengaruh oleh faktor kejernihan air laut.…”

Marine geological survey of Ekspedisi Widya Nusantara (EWIN) LIPI 2016 was conducted by using RV Baruna Jaya VIII in the Sumba Waters from 4 to 26 August 2016. One of the aim of this survey is to understand the sea floor surface sediment characteristics and its influence to the benthic foraminifera distribution. Seven sediment samples were collected from sea floor surface in Sumba Strait, at the different location and depth using grabbing method with box corer. The samples have analyzed for the foraminifera content, sediment grain size, organic matter and carbonate content, and chemical element by XRF method. The living benthic foraminifera distribution increase to the east of the research area, which have higher content of the organic material and Fe, Rb, Zr, Zn and Sr elements in the sediment. The benthic foraminifera distribution most abundance founded at the depth of 800-1000 m with sediment types are sandy coarse silt to sandy very coarse silt.Keywords: Benthic foraminifera, distribution, sea floor sediment, Sumba Strait.

“…Stasiun 3 dan stasiun 6 didominasi oleh Amphistegina masingmasing sebanyak 782 individu dan 2278 individu. Sedimen permukaan dengan klasifikasi lanau pasiran sedikit kerikil dan pasir dicirikan oleh kemunculan genus Amphistegina dan dapat juga ditemukan Quinqueloculina (Dewi dan Saputro, 2013). Genus Amphistegina yang dominan pada stasiun 3 dan stasiun 6 dapat terjadi karena kandungan fraksi pasir yang cukup tinggi.…”

The distribution of foraminifera is influenced by several environmental factors such as depth, sediment type, chemical and physical oceanographic paramaters, and season. The aim of the study was to determine the foraminiferal assemblages and their relationship to physical and chemical parameters in the offshore of Balikpapan waters of Makassar Strait such as depth, temperature, currents, sediment types, and salinity. Surface sediment, physical, and chemical parameters sampling was conducted in April 2012. The results of the observations on the sediment samples recognized planktonic foraminifera in 6 genera and 40 genera of benthic foraminifera from the 6 stations. Biodiversity of planktonic foraminifera was categorized in a low category with a range of 0.198-0.525. However, biodiversity for benthic foraminifera was categorized in a high category with a range of 0.811-0.925. Dominance of planktonic foraminifera was medium to high with range of 0.474-0.802 which was assumed due to the sampling sites as an open waters. Meanwhile, dominance for benthic foraminifera was in a low category with range of 0.075-0.189. The most common planktonic foraminifera was found from Genus Globigerina (10538 individuals). While, the most abundant of benthic foraminifera was found from Genus Amphistegina (3134 individuals). Keywords: abundance, foraminifera, sediment, and Makassar Strait
