ABSTRACT : Motor vehicle emissions have emerged as a significant global concern, adversely impacting air quality, human health, and environmental sustainability. In Indonesia, accelerated urbanization and the rising quantity of motor vehicles have exacerbated this issue, resulting in elevated carbon dioxide (CO₂) emissions. Vegetation is one of the most efficient natural solutions for reducing CO₂ pollution, as plants are essential for carbon sequestration by absorbing CO₂ from the atmosphere. This study aims to evaluate CO₂ emissions generated by vehicular operations and assess the CO₂ absorption capability along Drs. Esau Sesa Road to Trikora Arfai Manokwari Road. The quantitative research approach indicates that transportation activities on Drs. Esau Sesa Road produce approximately 20.843.795,10 kg/year of CO₂ emissions. Twenty-one tree species, comprising 136 individual trees, were discovered along the route. The total CO₂ absorption capacity of these trees is 140.740,00 kg/year, with Gersen (Muntingia calabura) demonstrating the greatest absorption potential at 56.286,86 kg/year. These findings highlight the significance of urban green spaces in alleviating air pollution and enhancing environmental quality. Enhancing afforestation initiatives and incorporating vegetation into urban planning are crucial measures for mitigating transportation-related emissions and fostering sustainable urban development. Future research should investigate supplementary techniques to augment CO₂ absorption capacity using various plant species and urban forestry programs.

Zooplankton play an important dual role in marine ecosystems as food webs connectors and sensitive indicators of water quality. This study examines the composition, abundance, and relationship of zooplankton communities with oceanographic parameters in the coral reef ecosystem of Manokwari Waters. Samples were collected from three observation stations: Kaki Island, Lemon Island, and Marampa Port, using a 25 μm plankton net. Morphological identification resulted in six classes of zooplankton, namely Hexanauplia, Gastropoda, Bivalve, Malacostraca, Branchiopoda, and Ostracoda, for a total of 23 species. The class Hexanauplia dominates in all locations, with the most abundant species being Undinula vulgaris (10 individuals), Calanus sinicus (7), and Eurytemora pacifica (6). Cluster analysis based on the Bray-Curtis similarity index with the Average Linkage method shows the similarity of zooplankton communities between Marampa Port and Lemon Island. Kaki Island forms a separate cluster, indicating differences in species composition spatially. The highest abundance was recorded in the Hexanauplia class with an abundance index of >2,500 cells/L in some species. Canonical Correspondence Analysis (CCA) revealed a positive correlation between DO and Bivalvia (+0.99), temperature with Gastropoda (+0.92), and salinity with Hexanauplia (+0.28). Environmental factors such as temperature, DO, pH, and depth have been shown to influence the spatial distribution and diversity of communities. These findings reinforce the dual role of zooplankton as a fundamental food source for benthic organisms such as the soft coral Sarcophyton sp. and as an effective bioindicator for monitoring the health of tropical coastal ecosystems.

Mikro-habitat ikan pelangi endemik Melanotaenia arfakensis dan implikasinya bagi konservasi insitu di Kebar, Papua Barat Daya

Wed, 30 Jul 2025 06:48:35 +0000

ABSTRACT: This study examines the microhabitat characteristics of the endemic rainbowfish Melanotaenia arfakensis in two major rivers of Tambrauw, Southwest Papua—Api River and Asiti River—focusing on the spatial dynamics of environmental parameters from upstream to downstream. Results indicate that water temperature, dissolved oxygen (DO), depth, current velocity, and river width show significant spatial trends and directly influence the survival of M. arfakensis. The upstream zones, characterized by lower temperatures (23–26°C), high DO levels (>7 mg/L), moderate current, and stable depth, are identified as optimal habitats and conservation priorities. In contrast, the midstream and downstream zones exhibit gradual habitat degradation, including temperature increases up to 29.1°C and decreased DO levels, approaching the physiological tolerance limits of the species. This decline in microhabitat quality correlates with riparian vegetation loss and anthropogenic pressures. Therefore, an effective in situ conservation strategy must be spatially explicit, adaptive, and participatory—emphasizing thermal refugia protection in the upstream zones, ecological restoration in the midstream, and integrated watershed management with community involvement in the downstream areas. Longitudinal connectivity and the integrity of the entire riverine ecosystem are essential for ensuring the long-term viability of this endemic species.

ABSTRACT : The Victoria crowned pigeon (Goura cristata), known for its beautiful crest, is an endemic species of Papua and is currently listed as “Near Threatened.” Therefore, conservation efforts such as captive breeding are necessary. This pigeon has the potential to be kept in captivity due to its tamable nature; however, biological information regarding its natural behavior is still needed. This study aims to describe the natural behavior of the Victoria crowned pigeon (Goura cristata) on Yapen Island. The research was conducted in April 2024 along the Siwiri River in the eastern region of Yapen Island. A field survey method was used, with bird activity observed at three locations (downstream, midstream, and upstream). Observations were carried out over three days at each site, from 06:00 to 18:00 Eastern Indonesian Time (WIT), with 60-minute observation intervals. Bird activities were observed directly or with binoculars. The behavioral observation used the scan sampling method, and activity data were recorded using the One-Zero Sampling method. The variables observed in this study were the activity times and the percentage frequency of Victoria crowned pigeon (Goura victoria) behaviors. Five types of natural behavior were identified at the research sites: feeding (31%), vocalizing (26%), walking (16%), grooming (14%), and defecating (13%). Feeding was the most frequently observed behavior, while defecating was the least frequent. Most behaviors occurred in the morning across all three locations—downstream, midstream, and upstream. Some behaviors occurred at different times of the day, likely due to environmental differences related to habitat, topography, and abiotic factors. The conclusion of this study is that any attempt to breed the Victoria crowned pigeon in captivity must consider both biotic and abiotic factors.

ABSTRACT: The rabbitfish, Siganus canaliculatus is one of the components in the coastal waters ecosystem (mangrove, seagrass, and coral reef) and also has important economic value for coastal communities, but information is still limited, especially in Papuan waters. This study aims to analyze the size composition and growth patterns of rabbitfish (Siganus canaliculatus) based on habitat differences in the waters of Kwatisore, Yaur District, Nabire Regency. Sampling was carried out at three locations representing various habitat types, such as mangrove, seagrass, and coral reef. The data collected included the total length (mm) and body weight (g) of the fish, which were then analyzed using the length-weight relationship model W = aL^b. The results showed that the average body length and average body weight were greater in the coral reef habitat type, but relatively the same among the three research locations. The overall growth pattern (habitat type and location) with a tendency for body length to increase faster than body weight (negative allometric pattern) with a b value ranging from 2.771 to 2.888. The size and growth patterns obtained in this study indicate connectivity between locations and habitats, although both habitat types show different roles in the life cycle of this fish. This study provides important information for ecosystem-based management of the rabbitfish resource in the coastal area of Nabire.
