Abstract

Background: Bird conservation in Indonesia is still focused on the areas of conservation of specified government. As in the nature reserves, wildlife clan asylum and national park. Nevertheless there are birds that live outside conservation areas such as forest city. DKI Jakarta as the capital city of Indonesia with a population of the most populous and has a forest city as a habitat of birds in urban areas, it become necessary to know research, equity, diversity, wealth, abundance, similarity species of birds, the difference in noise level and noise influence toward activity-voiced bird in three forest city of DKI Jakarta. Methods: Data retrieval method using point count with 24 point edge and central region in each forest city. Findings: Based on the findings presented in Chapter IV of the thesis, the study showed that higher noise levels and greater human presence significantly reduced bird vocal activity across three urban forests in Jakarta. The average noise level was highest in PT JIEP City Forest (66.55 dB), while human activity peaked in Hutan Kota Srengseng with 152 individuals recorded. A statistically relevant pattern was found: bird vocalization activity and the number of vocalizing birds were highest in areas with lower noise and human presence, supporting the hypothesis that anthropogenic disturbance negatively impacts bird behavior. Conclusion: This study reveals that noise levels and human presence significantly affect bird vocal activity and species diversity in urban forests of Jakarta, with lower noise and fewer people correlating with higher bird sound activity and diversity, highlighting the ecological importance of preserving and managing these green spaces. Novelty/Originality of this article: This study presents a novel investigation by integrating spatial (edge vs. center zones).

Abstract

 The study of macrozoobenthic in seaweed culture in Muara Gembong Estuary, Bekasi District, West Java Province, was conducted in May to July 2018. The study was aimed at understanding the roles of macrozoobenthic organisms as ecosystem engineering in seaweed habitat by identifying macrozoobenthic community structures using various biological indices. Sampling sites were conducted at three selected intertidal ponds used for seaweed culture at different distances and perpendicular to the coastline. Samples of macrozoobenthic organisms were collected using an Ekman grab during low tide periods. The study results showed that the macrozoobenthic community from the three ponds were consisted of 9 major benthic families and 14 genera with a total of 139 individuals. The results also showed that gastropod of the genus Cerithiidae was the dominant taxa found in every pond which contributed to 42.45% of the total macrozoobenthic found in the three ponds and became the main contributing taxa to the macrozoobenthic community structure. In addition, genus Platynereis of the Polychaeta Class was found to be another important taxon which contributed to 14.39% of the total macrozoobenthic found in the three ponds. The genus Platynereis were mostly found in the second pond with muddy coarse sandy sediment substrate containing more silt compared to the other two ponds. The rare taxon was the genus Lithophaga from family Mytilidae represented by 1 individual. Our study concluded that the macrozoobenthic community structure in the three ponds was categorized as poorly diverse indicating that the pond system was unstable. The Shannon-Wiener Diversity Index (H’) was only 0.87 on average with the highest diversity index (H’=1.47) was found in the third pond located at the farthest area of the coastline. Meanwhile, the average of Evenness Index was 0.34 indicating that the distribution of the taxa was uneven with a tendency of being dominated by certain taxa.

Abstract

ARTICLE HIGLIGHTS- The study in Ujung Genteng coast presents clear evidence of moderate macroalgae diversities and community structure linked to environmental parameters and substrate type- The biological indices scores illustrated a spatial distribution pattern of macroalgae assemblages- Understanding these ecological dynamics of macroalgae is crucial for both conservation and sustainable seaweed cultivation.ABSTRACTThe study of benthic macroalgae in Ujung Genteng aimed to describe the spatial distribution pattern of benthic macroalgae based on various parameters that support their growth and influence the health status of the marine ecosystem. The study was conducted from May to December 2023. The observation sites were selected using a purposive sampling method across three coastal areas, chosen based on the physical landscape structure and distinct substrate types. The line transect quadrat method was used for data collection. The study identified 41 species of benthic macroalgae from 28 genera and 19 families. The bubble green algae Boergesenia forbesii emerged as the dominant species, accounting for 16.8% of the assemblages, although this difference was not statistically significant. The distribution pattern of macroalgae showed noticeable spatial variation, with the East Zone, located in the eastern part of the coastal area, considered the most favourable habitat, harbouring 32 species with 312 individuals. The health status of the marine ecosystem in Ujung Genteng was relatively good, indicated by moderate Diversity Index (H’) values around 2.52 to 2.70, high Evenness Index (E) values (0.73 to 0.82), and low Dominance Index (D) values (0.09 to 0.11). The measured abiotic factors also fell within ranges that support the growth of benthic macroalgae. Keywords: benthic macroalgae, spatial, distribution patterns, Ujung Genteng
