Macrobenthos community structure in coral reef ecosystem around Pramuka Island, Jakarta

Abstract

Macrobenthos are organisms that live crawling, sessile, and digging holes in substrates such as sand, silt, rock, coral fragments, or dead coral. Benthos have low mobility, easy to catch, have a long life, and sensitive to some pollutants so that it can mean that benthic community structure can be used as a parameter of condition the current ecosystem of a particular area and also as information about wealth contained in the aquatic area. The study was conducted on 6-14 September 2018 in the Pramuka Island area, Kepulauan Seribu district, Indonesia. The collection of ecological data was carried out at seven different observation stations. Along with the rapid development of facilities on this island, there are threats both directly and indirectly to the preservation of the coral reef ecosystem around the Pramuka Island. The method used in collecting macrobenthos data is the Belt Transect method and collecting diversity index, evenness index, dominance index, and density. During the observation at the seven observation stations, 94 species of the seven macrobenthos phylum with the highest phylum were found, namely the Chordata phylum. The species most commonly found is Atriolum robustum. Diversity Index at each station in shallow depth and in the medium category. The evenness value obtained indicates a stable community condition. The highest index of dominance occurred at Pramuka Island Dock. Macrobenthos conditions from seven observation stations on Pramuka Island and its surroundings are still relatively good.

Revealing macrozoobenthos diversity of Java coral reefs, Indonesia: a review on research trends and species assemblages

“…In the western coast of Java (R1), a baseline coral reef ecosystem study was conducted off Sangiang Island (Yusri et al, 2017). Other works describe further explorations of macrozoobenthic diversity and community structure (Ali et al, 2017;Mustagfirin and Hartati, 2017;Panggarbesi et al, 2017;Siddiqi et al, 2017;Amfa et al, 2020;Sasongko et al, 2020;Hartati et al, 2021;Alamsyah et al, 2022), its potential utilization (Sulardiono, 2016;Ernawati et al, 2019), and responses to environmental conditions (Setyowati et al, 2017;Suryanti et al, 2018bSuryanti et al, , 2018aPratiwi, 2019;Fitriyah et al, 2020). Additionally, nudibranch species sampled from Karimunjawa and Bali were listed in bioactive compound research (Kristiana et al, 2020).…”

Fuzzy Comprehensive Evaluation of Qinghe Water Environment Based on Biometric Index of Macrobenthos Community Biological Index

“…Qinghe River, known as Shaobei River in ancient times, was named Qinghe River in the early Qing Dynasty due to its clear water quality [4]. The Qinghe River Basin is the main stream on the east bank of the Liaohe River system, most of which belong to the low mountain and hilly areas of the Changbai Mountains; it flows through the Qinghe District and Kaiyuan City under the jurisdiction of Tieling.…”

Temporal study of coral reef health in Kepulauan Seribu Marine National Park

“…According to [7], coral reef health can be seen benthic component and reef fish component. In addition, other coral association biota such as benthos have an important role to be a parameter to determine coral reef health [8] because these organism are sensitive to pollutants and can be a water indicator [9]. The condition of coral reef currently being threatened not only influence by nature, but also from human activities through pollution and habitat change.…”
