Abstract

The orangutan, a vital component of the rainforest ecosystem, is increasingly threatened by habitat loss and fragmentation. Identifying orangutan nests and feeding trees is an important elements in understanding the habitat's capacity to sustain this species. Using the transect method, this study was conducted on 40 grids out of a total of 623 grids in the Tripa area that are still covered by forest. This study aimed to record the presence of orangutan nests and identify various plant species that serve as food sources for orangutans. The result revealed the discovery of orangutan nests in 7 locations, most of which were categorized as type C (old) and type D (very old). A total of 13 potential orangutan food plant species were found in the Rawa Tripa forest area, consisting of the families Moraceae, Euphorbiaceae, Annonaceae, Myrtaceae, Myristicaceae, Apocynaceae, Piperaceae, Dipterocarpaceae, Urticaceae, and Pandanaceae. This suggest that these areas may have supported a significant orangutan population in the past, but their current activity appears to be declining. The findings underscore the need for conservation efforts, as the continued survival of orangutans is crucial not only for their species but also for the ecological health of the forests they inhabit.

Abstract

Background: The study conducted in the Pocut Meurah Intan Forest Park (TAHURA PMI) area aimed to analyze the outgoing activity of Heterotrigona itama worker beehives and their relationship with environmental and physical factors such as temperature, humidity, and light intensity. Methods: H. itama activity is observed from 06.00 to 18.00 WIB. Bees exiting the hive are counted using manual counting to determine the number of individuals that exit the hive for 10 minutes every hour. Observation of activities outside the nest consists of foraging, throwing garbage, and drones guarding the nest. Results showed that the peak of activity out of H. itama nests occurred at 09.00 - 10.00 WIB and 13.30 - 14.30 WIB. Results: Foraging activity was the highest nest exit activity. The relationship between light intensity factor and activity outside the foraging nest is moderate (R2 = 0.651), while temperature and humidity are weak (R2 = 0.052 and 0.091). The activity of exiting the nest to throw garbage has a moderate relationship with light intensity (R2 = 0.439) compared to temperature (R2 = 0.253) and humidity (R2 = 0.296). Furthermore, physical factors of light intensity (R2 = 0.6217) had a greater relationship with drone activity out of the nest than factors of temperature (R2 = 0.4385) and humidity (R2 = 0.4063). Activity outside the nest is positively correlated with temperature and light intensity and negatively correlated with humidity. Conclusions: Thus, it can be concluded that light intensity has the greatest influence on the activity out of the nest.

Abstract

Peat ecosystems are one of the tropical ecosystems that have high ecological value because they play a role in carbon storage, hydrological regulation, and as a habitat for various fauna groups, including birds. Rawa Tripa, as part of the Leuser Ecosystem Area, is one of the most important peat landscapes in Aceh that faces anthropogenic pressures such as forest fragmentation and land use change. The lack of basic data on bird communities in this area hinders evidence-based conservation efforts. This study aims to inventory the bird species found in the Tripa Peat Forest and assess their conservation value in the context of habitat management. The survey was conducted from July 18 to 28, 2024, using the point count method on 10 observation transects. The results of the study recorded 16 bird species from 12 families, with the Pycnonotidae family being the most commonly found group. Several species with important conservation status were also identified, such as Leptoptilos javanicus (Near Threatened), Acridotheres javanicus (Vulnerable), and the presence of Rhyticeros undulatus (Vulnerable) and their nest, indicating the availability of large trees for nesting. Based on their feeding behavior, the birds of Rawa Tripa exhibit a diversity of ecological functions, ranging from insectivores and frugivores to raptors. These findings indicate that Rawa Tripa still has habitat quality that supports bird communities, even though threats such as hunting and land degradation remain. This study emphasizes the urgency of long-term monitoring and the need for conservation strategies that maintain vegetation structure and wetland sustainability in the Rawa Tripa area.
