Abstract. Husodo T, Megantara EN, Mutaqin AZ, Kendarto DR, Wulandari I, Shanida SS. 2022. Short Communication: Leopard cat (Prionailurus bengalensis) distribution in the Cisokan Hydropower Plant, West Java, Indonesia. Biodiversitas 23: 6247-6253. Globally, leopard cats (Prionailurus bengalensis) can be found in various land cover types. Information about leopard cats is still low in Indonesia, especially in Java. Java Island has high human activities that impact leopard cats, such as the UCPS hydropower development area, a non-conservation area. The UCPS hydropower plant is in the upper catchment area of ??the Cisokan River as a tributary of the Citarum River. Although leopard cats can adapt to various land cover types, monitoring their existence is necessary. This study aims to reveal the distribution of leopard cats in the UCPS hydropower development area, Cianjur Regency and West Bandung Regency, West Java, Indonesia. Sign survey and literature were applied in this study. Fifty-eight leopard cat findings were found in the UCPS hydropower area. Leopard cats were found in 16 of the 47 grids from 2012-2022. After 5-10 years, leopard cats still use the same area in certain areas to meet their needs.In eight of 16 grids, 50% of the grids used by leopard cats were habitats used repeatedly. They were most commonly found in shrubs (39%), riparian (20%), and pine plantations (15%). Leopard cats were located at 445-895 masl and are most commonly found at 400-800 masl. Leopard cats are found in the UCPS development area and Perhutani Land. After 5-10 years, leopard cats still use the UCPS development area, so the habitat still fulfills their daily needs. Further monitoring is needed to determine the ecological status of the leopard cat population during the construction and post-construction process.

Abstract. Mutaqin AZ, Husodo T, Kendarto DR, Wulandari I, Shanida SS, Megantara EN, Kurniadie D, Iskandar J, Nurzaman M. 2022. The ecology of suweg (Amorphophallus paeoniifolius) in the Citanduy and Cimanuk Watershed, West Java, Indonesia. Biodiversitas 23: 6520-6529. Suweg (Amorphophallus paeoniifolius (Dennst.) Nicolson) is one of the plants distributed in Indonesia, including in the Citanduy and Cimanuk Watershed. Amorphophallus grows in various land cover types. This species exhibits wide agroecological adaptation to dry and moist lands. Citanduy Watershed passes through the Leuwikeris Dam, and the Cimanuk watershed passes through the Kertajati International Airport. These projects can affect the condition of the surrounding environment, including biodiversity. This study was conducted to observe the distribution, population, and habitat characteristics of the suweg in the Citanduy and Cimanuk watersheds. Exploratory surveys and intensive studies were applied in this study. An exploratory survey was conducted randomly through direct observation. An intensive study was carried out to determine the ecological description of suweg in several areas, namely Kuta Subvillage, Ciangir Subvillage, and Pasiripis Village, with existing projects, still have strong local cultures, and the discovery of suweg growing. Suweg is growing in several sites, including the Citanduy and Cimanuk Watersheds, with certain elevations and environmental conditions. The Summed Dominant Ratio (SDR) of suweg in Kuta Subvillage, Ciangir Subvillage, and Pasiripis Village in the home garden and garden, respectively, are 8.50 and 13.77; 10.07 and 19.25; and 0 and 22.92, which indicate the population or density of suweg is low. The abiotic and biotic environmental parameters observed at each site varied.

Abstract. Mutaqin AZ, Iskandar J, Irawan B, Suryana, Kurnadie D, Nurzaman M, Shanida SS. 2023. The local knowledge and potential of suweg (Amorphophallus paeoniifolius) in the Citanduy and Cimanuk watersheds of West Java, Indonesia. Biodiversitas 24: 370-378. The Indonesian archipelago is rich in natural resources and ethnic diversity. Each ethnic group interacts with the surrounding environment in ways that often differ. Interaction with the environment creates local knowledge that is complex in terms of language, practical understanding, beliefs, and social interaction. One useful natural resource that grows in many areas of Indonesia, especially in watershed ecosystems, is Suweg (the elephant foot yam) which has the scientific name Amorphophallus paeoniifolius (Dennst.) Nicolson. Local communities, such as in the Citanduy and Cimanuk watersheds of West Java, use suweg for various purposes in their lives. The study reported here aimed to document the local knowledge and development potential for suweg in the Citanduy and Cimanuk watersheds, West Java, Indonesia. The research used mixed observation methods, predominantly qualitative. The data collection technique was purposive, based on interviews (structured, semi-structured, and in-depth interviews) with several informants or community groups who were considered competent to know suweg. Data were analyzed through emic and ethical approaches. Data analysis was conducted by cross-checking, summarizing, and synthesizing. The results of the research showed that suweg grows in a range of environmental conditions on managed agroecosystem lands. The corms of suweg are peeled, cooked and eaten in a variety of side dishes. The leaves of suweg have been used as food for fish in pond-system aquaculture. The results of this study suggest that suweg has the potential for expanded development, based on sociological and ecological evidence.

Abstract. Megantara EN, Husodo T, Kendarto DR, Mutaqin AZ, Withaningsih S, Wulandari I, Shanida SS, Febrianto P, Hendrawan R. 2024. Short Communication: Records of Java mouse-deer (Tragulus javanicus Gmelin, 1788) in the Cisokan forest patches, West Java, Indonesia. Biodiversitas 25: 2713-2719. Mammals are bioindicators in terrestrial ecosystems due to their influence on the conservation of other species and in maintaining ecosystem balance, such as the Java mouse-deer (Tragulus javanicus Gmelin, 1788), which contributes to seed disperser on the forest floor. Information on the presence of Java mouse-deer is still limited to mammalian diversity studies; therefore, little information focuses on Java mouse-deer studies, especially in the non-conservation areas and infrastructure development areas, such as the Upper Cisokan Pumped Storage (UCPS) development in the Cianjur and West Bandung Districts. This study aims to reveal the presence of Java mouse-deer in the UCPS hydropower development area, West Java. The studies were conducted in February 2017, August 2020, and September 2022. Sign survey, camera trapping, and literature review were applied to this study. Java mouse-deer was found for ten years in the UCPS area. Java mouse-deer was found both directly and indirectly (footprints and feces). Java mouse-deer were discovered in 2012, 2017, 2020, and 2022 in the UCPS area. This species was found in the secondary forest (forest patches), shrubs, mixed gardens, and plantations. This species was most abundant in shrubs and mixed gardens near paddy fields with high levels of human activity. In shrub areas, the topography tends to be cliffy with a dense canopy, making it difficult for humans to pass. Shrub cover is dominated by calliandra (Calliandra calothyrsus Meisn.), wild sugarcane (Saccharum spontaneum L.), siam weed (Eupatorium odoratum L.), and billygoat-weed (Ageratum conyzoides L.). Java mouse-deer have been encountered for ten years. Agricultural and construction activities affect the opportunities to encounter the species. Longer-term monitoring of the densities will be essential to reveal the population of Java mouse-deer and how its distribution impacted the development of hydropower plants.

Abstract. Megantara EN, Husodo T, Mutaqin AZ, Kendarto DR, Wulandari I, Pujianto MP, Shanida SS, Afriyanti F. 2025. Exploring habitat characteristics and herpetofauna diversity in the Kamojang and Darajat Geothermal Power Plants, West Java, Indonesia. Biodiversitas 26: 203-222. Considering their vital role in preserving ecological stability, herpetofauna are essential indicators of the environment's health. From 2019 to 2023, this project examines the herpetofauna's habitat and variety surrounding the Kamojang and Darajat Geothermal Power Plants, West Java, Indonesia. The study's objectives were to monitor species diversity, evaluate habitat conditions, and understand how land use changes affect these species. Data were gathered by vegetation analysis and visual and auditory encounter surveys in various land cover types, including natural forests, mixed gardens, pine plantations, shrubs, swamps, riparian, artificial gardens, craters, and replanting areas. The results identified 37 species of herpetofauna, including 18 amphibians and 19 reptiles. Vegetation analysis revealed that natural forests and riparian zones supported the highest species richness. In contrast, areas with monoculture vegetation, such as pine plantations, had lower biodiversity. Natural habitats tend to have lower temperatures and high humidity, creating ideal conditions for specialist species requiring a stable and humid environment. In contrast, artificial habitats have warmer temperatures and lower humidity, favoring generalist species, which are more adaptable to variable environmental conditions. Artificial habitats also provide diverse microhabitats, such as open areas for basking and shade from plant canopies, which favor certain reptiles and amphibians. Adapting species to these different conditions reflects the importance of maintaining a balance between natural habitats to support specialist species and artificial habitats for more flexible species. This combination of abiotic factors and habitat structure is key to the sustainability of herpetofauna diversity in both areas. Habitat quality was affected by human activities such as land conversion and agriculture, which decreased the diversity of herpetofauna and the vegetation structure. This study emphasizes the significance of habitat conservation and sustainable land management in maintaining biodiversity in geothermal areas.
