Abstract

Kaliage Besar Island is one of the islands in Seribu Islands National Park, DKI Jakarta. Located in the Management Section of Kelapa Island Region I National Park. The island with the allotment of the use rights of the private island which is used as a public tourist and resort. Kaliage Besar Island still has the potential for highly productive coral reef resources. Currently, the coral reefs of Kaliage Besar Island has suffered damage caused by anthropogenic activities and natural factors. This research used Underwater Photo Transect/UPT method were analyzed using CPCe 4.1. software (Coral Point Count with Excel extension). Data collection was carried out at one research point with a depth of 3 m and a transect length of 20 m with 3 data collection times (10 m intervals between transects). The measurement physico-chemical parameters results was shown that water quality in Kaliage Besar Island was still within tolerance limits for coral life. The percentage of live coral cover was in a bad category with a low value 6,46%. Composition of hard coral genusis consists of 6 family, 7 genus, and 119 individuals. The most dominant genus is Porites with submassive and massive growth form. The index value of diversity shows a low category (0,42). The dominance index value showed a high category (0,84). Uniformity and mortality index value showed a low category (0,22 and 0,28).

Abstract

The construction of the embankment on Pulau Harapan aims to break the waves and protect the land from coastal abrasion. The construction of this embankment will provide many benefits for the community, but the implementation of its construction activities will, directly and indirectly, have an impact on the condition of the biota in the shallow sea waters of Pulau Harapan. To find out the impact of damage, it is necessary to conduct an initial study of the condition of coral reefs at the embankment construction site on Pulau Harapan. The purpose of this study is to obtain preliminary information on coral reef ecosystems. The method used in this research is the Underwater Photo Transect/UPT method which is then analyzed using CPCe 4.1 (Coral Point Count with Excel extension) software. The results of the physical and chemical measurements of the waters concluded that the quality of the waters at the observation site was still within the tolerance limits for coral life. The results of the analysis of the percentage of live coral cover are in the bad category with a percentage value of 17.1%. The composition of corals found were 5 families and 7 genera. The most commonly found coral genus is Porites. The dominance index value is 0.43 and is included in the low category and means that there is no dominant coral genus. The structure of the benthic community in the survey site area is dominated by sand and coral fragments that have been dead for a long time. The condition of the coral reef ecosystem in the observation area is classified as unstable.

Abstract

Birds are animals that are very closely related to human life, both to be used as food or to be distributed as a hobby. However, at this time the existence of birds in nature is increasingly experiencing a decline in diversity and is even threatened with extinction. The purpose of this study was to determine the types of birds traded in the city of Pontianak and Kubu Raya regency along with their IUCN status and trade status (CITES). This research was conducted in March-April 2021. The method used was direct observation (recording) and conducting interviews with bird shop owners. The data obtained were analyzed using qualitative descriptive analysis. Based on the results of research that has been done, the number of shops in Pontianak Cityis19 bird shops. Meanwhile, the number of shops in Kubu Raya Regencyis nine bird shops. The most common birds found in stores are from the Muscicapidae family, 48 species of birds traded with least concern (LC) status, five species of near threatened (NT), eight species of vulnerable (VU), and two species of critically endangered (CR). 58 bird species are not included in the CITES appendix list, one species is included in Appendix I, namely Zosterops palpebrosus, and four species are included in Appendix II, namely Leucopsar rothschildi, Garrulax canorus, Pycnonotus zeylanicus, and Melopsittacus undulates. Meanwhile, the majority of the birds (91%) found in the stores come from the wild compared to those from livestock (9%). The results also showed that wild birds were obtained by traders through hunting and buying from others.

Abstract

The sophisticated communications could be a tool as a driver to increase of the illegal wildlife trade. Since 2012 there has been a shift in the trend of illegal wildlife trade from the offline market to the online market (advertising, e-commerce and social media). This study aims to determine the role of new media in the dissemination of Indonesian Council of Ulama (MUI) Fatwa No. 4/2014 about The Protection of Endangered Species for the Balance of the Ecosystem (illegal wildlife trade fatwa). The research was carried out in April–August 2020 through the new media Facebook. Collecting wildlife trade data through Google trends for a period of 5 years (2015-2020). Google trends are used as a basic reference in determining targets for video dissemination through Facebook. The approach used is by using research methods through new media, content analysis resulting from video dissemination (such as impressions, engagement, opinions, and feelings). The results of the study show that new media can be an effective medium in conveying and developing conservation messages, particularly to reduce the illegal wildlife trade in Indonesia.

Abstract

The wild birds in nature can be threatened due to the increasing demand for birds for pets by some people. On the other hand, the bird trade can be an opportunity for gaining economic benefits. One of the highest demands of birds comes from Java, especially Jakarta. This study aims to determine the types of birds traded in bird shops in Jakarta along with their IUCN conservation status, the protection status according to the Ministry of Environment and Forestry Regulation No. 106 of 2018, and the CITES trading status. The research was conducted in April-May 2021. Data collection methods included direct observation (recording and recording) and interviews. The data were taken by purposively listing the bird shops. The data obtained were analyzed using qualitative descriptive analysis. The results show from sample area in Jakarta, we approached 57 bird traders (13 stores in Central Jakarta, 12 stores in North Jakarta, 12 stores in West Jakarta, 10 stores in East Jakarta, and 10 stores in South Jakarta). The birds found are coming from 42 bird families consisting of 117 species. 100 species are the least concern status, seven species are near threatened, one species is vulnerable, five species are endangered, and four species are critically endangered. Based on KLHK Ministerial Regulation No. 106 of 2018, there are 16 protected and 101 unprotected bird species. 113 bird species are not included in the CITES category, one species belongs to the appendix I category, three species belong to the appendix II category. Although in general the IUCN status of the traded birds is LC, a large number (73%) of the wild bird species were caught from nature. The survey shows the trend of the bird trade together with the increasing market demand may lead to population decline that caused rareness of the species and perhaps extinction.

Abstract

Orangutan conservation efforts can be carried out through habitat management both within and outside of conservation areas. The protected areas along the Rungau River has indications of an orangutan population. So, it is necessary to study the characteristics of nests and nest trees. The research method uses transect lines to record the characteristics of the nets and the characteristic of the nest tree. Based on research on the characteristics of the nest, it is known that the height of the nest ranges from 5 to 32 m from the ground. Class B is the dominant nest class. Dominant nest diameter of more than 1 m. Then the characteristics of the nest tree are known that the height of the nest tree ranges from 10 to 37 m. In adults, tree nests have a diameter at breast hight in the range of 5 to 96 cm. The dominant type of nest tree species are guava and meranti.

Abstract

Indonesia's coastal and marine ecosystems, including coral reefs, mangroves, and seagrass beds, play critical roles in maintaining biodiversity and ecological balance while providing essential ecosystem services such as coastal protection and food resources. This study evaluates the health of aquatic ecosystems on Pramuka Island and Kotok Besar Island by assessing macroalgal diversity and water quality parameters. Using a survey method with quadratic transects, we analyzed species composition, Shannon-Wiener diversity index, and important value index (IVI) of macroalgae, alongside measurements of physical (temperature, salinity, brightness, depth, current speed) and chemical (pH, dissolved oxygen) water parameters. Results identified 26 macroalgal species on Pramuka Island and 19 on Kotok Besar Island, with moderate diversity indices (H’=2.64 and H’=2.26, respectively). The dominant species were Halimeda macroloba (Chlorophyta) and Hypnea asperi (Rhodophyta) on Pramuka Island, and Halimeda macroloba (Chlorophyta) and Sargassum binderi (Phaeophyta) on Kotok Besar Island. Water quality across both islands remained within optimal ranges for macroalgal growth. These findings underscore the ecological significance of macroalgal communities as bioindicators and highlight the need for targeted conservation strategies to preserve these ecosystems amid rising anthropogenic pressures.

Abstract

Purse seine fisheries represent an important component of capture fishing activities conducted by local fishers in Weru Village, Lamongan Regency. However, spatial variations in catch composition and fish diversity across different fishing grounds are still poorly documented. This study aims to analyze fish community structure at four purse seine fishing locations through assessments of catch composition and ecological indices. Data were collected during July–August 2025 through direct observations at landing sites by recording the number of individuals for each species. Analytical procedures included the Shannon-Wiener Diversity Index (H’), Pielou’s Evenness Index (E), and Simpson’s Dominance Index (C) to evaluate community differences among locations. The results reveal clear spatial differences in fish community structure. In total, the purse seine fishery recorded 11 fish species with a total of 15,041 individuals across four fishing locations, indicating a marked disparity in catch abundance across the sites. Locations A and B were dominated by Hilsa kelee, with high catch numbers (3,886 and 7,286 individuals), resulting in low diversity (H’ = 0.18 and 0.06) and high dominance (C = 0.94 and 0.98). In contrast, location D demonstrated a more balanced and stable fish community structure, reflected in its notably higher diversity (H’ = 1.29), high evenness (E = 0.66), and low dominance (C = 0.40). These findings offer important baseline insights to support spatially informed management of small pelagic fisheries in the coastal.
