Abstract

The Javan Hawk-eagle Nisaetus bartelsi is a protected bird of prey endemic to Java Island and is one of Indonesia's mascot fauna. The survival of this species in nature is threatened, among others due to habitat degradation, and land use change around its habitat. This study was conducted to analyze the presence and characteristics of nests and the habitat around Javan eagle nests in the Gunung Salak 1 Resort area within the Gunung Halimun Salak National Park. The research was conducted using the Direct Observation method, with parameters namely characteristics of nest trees, and nests, as well as biotic and abiotic environments around Javan eagle nests. The results found the presence of active Javan eagle nests in the Hameurang Valley block in the Sintok area, and the Curug Cibadak block in the Loji area. The nest in Sintok was found in a beunying tree (Ficus fistulosa) in a natural forest, at 1,097 m above sea level. Nests in Loji were found in rasamala (Altingia excelsa) trees in the natural forest, at 1,347 m asl. The nest is located at the height of 15-22 m from the ground, round in shape, the nest material is epiphytic plants, branches of puspa (Schima wallichii), rasamala (Altingia excelsa), and manii (Maesopsis eminii). The plant around the nest with the highest INP in Sintok is the manii tree (Maeopsis emini), while in Loji it is the seuhang tree (Ficus grossulariodes).

Abstract

The Tea and Quinine Research Center (PPTK), Gambung is located in Mekarsari Village, Pasir Jambu, District, Bandung, West Java. This location borders the Gunung Tilu Nature Reserve in West Java. The lack of information about herpetofauna in this area prompted this research. The study was conducted using the Visual Encounter System (VES) method on three different transects with distinct characteristics: the Situ Kubang transect, which is an area along the riverbank; the Abikarna transect, which is a forest transect along a small stream; and the Kebun transect around the Tea and Coffee Plantations. Data collection was carried out for three days, by recording: encounters of herpetofauna species, as well as their habitat components, including weather, temperature, air humidity, air pH and canopy cover. The results revealed 15 species from 9 families, including 5 amphibian families and 4 reptile families. The species diversity index (H’) of herpetofauna across the three transects was categorized as moderate. The Kebun transect had the highest Diversity Index (H’) value of 1.90, followed by the Situ Kubang transect with 1.78, and the Abikarna transect with H’ = 1.23. The herpetofauna species with the highest number of encounter was Chalcorana chalconota with 25 individuals, while other species had low number encounter, with fewer than 3 individuals per species, including Bronchocela jubata, Takydromus sexlineatus, Pseudocalotes tympanistriga, Gongylosoma baliodeirus, Limnonectes kuhlii, Fejervarya limnocharis, Polypedates leucomystax, Rhacophorus margaritifer, and Microhyla achatina. The species Bronchocela jubata, Leptobrachium hasseltii, and Chalcorana chalconota were found on all research transects.

Abstract

Sumedang was one of the districts in West Java Province that consisted of 26 sub-districts, 7 neighborhoods, and 270 villages. Bangbayang Village, located in the Situraja neighborhood, was one of the villages with ecotourism potential that had not been fully developed. The topography of the village, characterized by hills, had its own charm, and its biodiversity had not been widely explored. One aspect of this biodiversity that had potential for ecotourism was the diversity of bird species found there. Therefore, the research aimed to explore the potential and diversity of birds in Bangbayang Village, Sumedang, in the context of developing birdwatching science and ecotourism. The research was conducted in January 2023. Birds were observed using the point count method, and the data were analyzed for conservation status, the Shannon-Wiener species diversity index, the Margalef richness index, bird species evenness, and the Simpson dominance index. The results identified 35 species of birds from 20 families, 12 of which were endemic to Indonesia. Among them, two species were classified as NT (Near Threatened), two as EN (Endangered), six were included in the CITES Appendix II category, and eight species were protected under Ministerial Regulation P.106 of 2018. The diversity index, species richness index, and evenness index values were high, recorded at 3.343, 7.575, and 0.940, respectively, while no bird species dominated, with a dominance index value of 0.043. Based on their status, nine species were identified as having potential for ecotourism attraction: the black eagle, javan hawk-eagle, crested serpent-eagle, oriental honey-buzzard, flame-fronted barbet, black-banded barbet, bar-winged prinia, black-thighed falconet, and java sparrow.

Abstract

The aim of this research is to determine the best shoot induction medium for Pandanus tectorius, a coastal plant valued for its ecological and economic benefits. Coastal degradation and land conversion have reduced its population, necessitating propagation efforts. In vitro culture was explored as a solution to address the scarcity of Pandanus tectorius. Woody Plant Medium (WPM) was prepared by combining 100 mL stock solution, 30 g sugar, and distilled water to 1 L, supplemented with 1 g activated charcoal, 0.1 g ascorbic acid, and plant growth regulators at varying concentrations. The pH was adjusted to 5.6–5.8, and agar was added before sterilization at 121 °C for 20 minutes. Explants consisting of 1 cm-long shoots were sterilized and cultured in bottles, with observations conducted over 8 weeks. Results showed that the best shoot induction was achieved using WPM supplemented with 5x10⁻⁶ M BAP and 5x10⁻⁶ M NAA, producing 1 to 3 shoots per explant. Data analysis using a factorial completely randomized design confirmed significant differences among treatments. This study demonstrates the effectiveness of in vitro propagation in restoring Pandanus tectorius populations and supports sustainable coastal management.

Abstract

Indonesia is one of the countries with the second highest biodiversity in the world, known as a megabiodiversity country. One of the highest biodiversity in Indonesia is butterflies, which belong to the order Lepidoptera. Butterflies have significant ecological value in ecosystems, acting as pollinators, environmental bioindicators, and ecosystem balancers. This research was conducted from May 1-5, 2024, in the Tea and Quinine Research Center Area, Pasir Jambu District, Bandung Regency, West Java. Butterfly observations were made in the morning from 08.00 to 12.00 WIB and in the afternoon from 13.00 to 16.00 in two types of gardens, namely tea gardens and coffee gardens. The data collection method used was the exploration method. Measurements of abiotic factors at the observation locations, including temperature, humidity, wind speed, and light intensity, showed differences in the two locations. In the observation locations, a total of 49 species and 366 individuals of butterflies were found. The similarity index of butterflies in the two habitat types was 57%. The butterfly diversity index in this study was 2.6 for the tea garden and 2.53 for the coffee garden. The Hutchinson test results showed no significant difference between the two habitats. The species evenness index in the tea garden was 0.74 and in the coffee garden was 0.73. The dominance index of butterflies in the two habitats was 0.2 for the coffee garden and 0.14 for the tea garden. The butterfly species with the highest number of individuals in the tea and coffee garden habitats were Ypthima pandocus and Delias belisama. The protected butterfly species found in the research location was Troides amphrysus.

Abstract

Indonesia, as the country with the highest number of primate species in Asia, also holds the largest number of endemic primates, including five species on the island of Java. This study aimed to assess the distribution and abundance of primate species in Gunung Sanggabuana, Karawang, West Java, one of the closest tropical rainforests to Jakarta. Field surveys were conducted during the dry season (11–14 September 2023) by the Primate Student Team of Field Biology Study (SBL). Recce transects were used for primate censuses and fruit trails for recording fruit-bearing plant abundances along two paths: the tourist area and semi-tourist area. Results indicated three primate species were directly encountered: Javan langur (Trachypithecus mauritius), Surili (Presbytis comata), and Javan gibbon (Hylobates moloch). In the Kejayaan-Burahol trail, Javan langurs were observed at 1 group/km (1–5 individuals), Surili at 0.5 groups/km (4 individuals), and Javan gibbons at 1 group/km (4–6 individuals). The Cigentis-Cipiit trail yielded higher Javan langur abundance at 1.5 groups/km (5–8 individuals). The dominance of Javan langur was noted with a low value of 0.160. These findings provide insight into primate distribution and abundance, contributing to conservation efforts in Gunung Sanggabuana and other Javan rainforests.

Abstract

Mount Sanggabuana with an altitude of 1,074 above the sea level has an exciting and high biodiversity. Still, currently, its status is being sought to officially become a National Park and not many research reports have been found that discuss birds in the area. The purpose of this paper is to determine the diversity of bird species in the Sanggabuana Area, Cintalaksana, Tegalwaru, Karawang, West Java. The research was conducted on 15-17 August 2024 using the point count method. Based on the results of observations, 26 bird species from 16 families were recorded and there are five bird species protected according to the Minister of Environment and Forestry Regulation No. 20 of 2018, one of which is the bido snake eagle (Spilornis cheela) from the Accipitridae. The diversity of bird species in the Sanggabuana area is classified in the medium category, details of the H' value in the primary forest (Jalur Hutan) of 2.54 and in the secondary forest (Jalur Curug) of 2.55. The dominating bird species in the primary forest habitat is Takur tohtor (Psilopogon armillaris) while in the secondary forest is Cucak kutilang (Pycnonotus aurigaster).

Abstract

The Cibubur Urban Forest, designated by the DKI Jakarta Regional Government as a conservation area, serves as a vital ecological patch supporting diverse plant vegetation and associated organisms. This study investigates the composition and diversity of soil arthropods within the forest, focusing on their ecological roles across different habitat types. Field research was conducted in March 2024 using pitfall traps (15 traps per habitat, filled with 70% alcohol) deployed for three days. Specimens were collected from four distinct habitats and classified taxonomically. Results identified six arthropod classes: Arachnida, Chilopoda, Collembola, Crustacea, Diplopoda, and Insecta, with Insecta being the most dominant. A total of 16 orders were recorded, with Collembola, Coleoptera, and Diptera exhibiting the highest abundance, while Mantodea and Isoptera were the least represented. Habitat 1 showed the highest arthropod diversity, whereas Plot 2 had the lowest. Ecological analysis revealed arthropod functions as predators, decomposers, scavengers, herbivores, and carnivores, underscoring their critical roles in maintaining forest ecosystem stability. These findings highlight the Cibubur Urban Forest’s significance as a biodiversity hotspot and emphasize the need for habitat-specific conservation strategies to preserve soil arthropod communities and their ecological services.
