Eagle is one of the animals that can be used as an indicator of environmental health because it has a high level of sensitivity to the environment. The loss of the eagle population in nature will cause ecosystem changes due to disruption of food webs. The Brontok Eagle (Nisaetus cirrhatus) is a type of eagle which according to the IUCN is classified as the least concern category, its existence in nature is not easy to find due to poaching and habitat destruction. Kamojang Eagle Conservation Center (PKEK) is a conservation organization whose function is to rehabilitate the eagles that have been kept. This research was conducted to find out indications of the breeding behavior of bald eagles in PKEK and to find out the differences in the breeding behavior of bald eagles in PKEK and eagles in nature. The method used is scan sampling with 5 minute intervals combined with the ad-libitum method. Based on the observations, the following proportions were obtained, 65% standing alone, 24% perched together, 8% flying and 3% making sounds. Based on these data, indications of breeding behavior have been observed, but it has not yet become the dominant behavior. The indications of observed breeding behavior were perched together. There is a difference in mating behavior between the Brontok eagles in PKEK and the eagles in nature, that is, they do not observe the behavior of flying together.

Taman Hutan Raya (TAHURA) Ir. H. Djuanda Bandung is an integrated conservation area in which there are secondary natural forests that have various kinds of flora and fauna. Macrofungi are fungi whose fruiting bodies can be seen directly without the aid of a microscope, heterotrophic, and ecologically act as decomposers of organic matter (decomposers) and as biological control agents. Data related to research results on macrofungi in the Tahura area is still limited and need more comprehensive research. This study aimed to inventory, determine the growth factors, and potential utilization of macroscopic fungi. Observations were carried out during the period of November 2021 - April 2022 using exploration method. Sampling was done by purposive sampling method. Macrofungi identification process was carried out based on morphological characters such as cap, stalk, and lamella, The environmental factors observed included air humidity, soil pH, temperature, and type of substrate. The results showed that as many as 83 species were found in the Protection block, 50 species were found in the Collection block, and 99 species were identified in the Utilization block from the phyla Basidiomycota and Ascomycota. The macrofungi found have potential as biodegradation agents, food ingredients, non-food ingredients, drugs, antimicrobials, antioxidants, anticancer, and anti-inflammatory.

Sanghyang Kenit Cave is a cave that has an aquatic environment and a potential habitat for plankton. Plankton can be a bioindicator of water because of its sensitivity to the environment. The purpose of this study was to determine the diversity, interrelationship factors, and linkages of plankton with the environment in the waters of Sanghyang Kenit Rajamandala Cave, West Bandung. This research was conducted from August 2021 to September 2022. The study employed a purposive sampling method, identifying three sampling zones (The Light, Twilight, and Dark zones) during morning, afternoon, and evening periods. Sampling was done by taking a sample of 10 liters and then filtering using plankton net. The Physico-chemical parameters measured included water temperature, light intensity, pH, DO, salinity, nitrate, and phosphate. Based on the results of data analysis found 4 classes with 12 plankton morphospecies. Diversity index values in the Light zone (1.10), Twilight zone (1.08), and dark zone (1.08). Abundance index value in the light zone is 2.537 cells/l, the twilight zone is 501 cells/l, and the dark zone is 29 cells/l. Diversity and plankton in the waters of Sanghyang Kenit Cave have a very strong correlation with water temperature, light intensity, and pH of water. This can be the basis for the development of further research on the management and monitoring of caves that are used as tourist attractions.KeywordsDiversityPlanktonSanghyang Kenit CaveEnvironment

Human activity along the river impacts the aquatic environment from biotic and abiotic factors. One indicator that can reflect the quality of the waters is fish diversity. Several studies have used fish diversity as a biological indicator to determine the quality of waters, such as lake and river waters. The purpose of this study was to determine the diversity of fish and also to determine the quality of water in the Cikapundung River, Bandung City. The method used in this study was a survey and exploration method, which involved collecting samples at five stations using umbrella traps, cast nets, and fishing gear in the morning and evening. The fish obtained were identified using the Fish Identification Guidebook, and the number of each type was calculated. The biotic data obtained were processed using the Shannon-Weiner diversity index (H'), Evenness index (E), Margalef Abundance index (Dmg), and Simpson Dominance index (C). In contrast, the abiotic data were sent to the water quality testing institution (LPKL). The study's results identified seven species from 5 families: Cyprinus sp., Ancistrus sp., Xiphophorus sp., Barbodes sp. According to the Shannon-Weiner index, the diversity of fish species in the Cikapundung River in Bandung City is relatively moderate, with a value (H') of 1.55. The results of water quality measurements of the Cikapundung River from LPKL based on the class II water quality standards of PP RI Number 22 of 2021 show that the condition of the river is in the moderately polluted category.
