Abstract

ABSTRACT: This study aimed to identify indigenous bacterial isolates producing Amylase ezyme from sago starch from Poom, Yapen Islands, using the 16S rDNA sequence molecular method. The isolates identified were IA4 and IA8, which exhibited the highest values of assimilase enzyme activity. Bacteria were identified based on DNA amplification using Polymerase Chain Reaction (PCR) with primers 27F and 1492R. Based on the results of molecular identification, the similarity index of Isolate IA4 and Bacillus cereus D21 is 97.80%, while isolate IA8 had a similarity index of 99.79% with Alcaligenes faecalis Y5. Therefore, the amylolytic bacterial isolates were named Bacillus cereus strain IA4 and Alcaligenes faecalis strain IA8.

Abstract

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.

Abstract

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 = aLb. 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.

Abstract

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.

Abstract

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

ABSTRACT: Over the last four decades, large-scale forest management in Papua has failed to deliver wealth for most Papuans, and even the minus reveals that Papuans are the poorest in Indonesia. Environmental sustainability is improving, and increased community participation in teak forest management will impact the economy (community income increases) and the ecology. Forest management is linked to local knowledge or how humans see and act due to their interpretation of the natural environment, which is interwoven into the cultural system. This study used a descriptive qualitative research approach from January to February 2022 in Abenaho District, Yalimo Regency. The findings of a study on the usage of traditional woods by the Yali tribal population in Abenaho District reveal two distinct characteristics of the area, which may be seen in the management and utilisation activities of these traditional forests. Traditional forest utilisation systems such as farming/gardening, use of forest products, flora and fauna are also found to differ between the villages of Uwambo, Yahatma, Elesim Amuki, Kefido and Horenikma, Usabie, Kelesu, Kaboholik, and Suele.

Abstract

Kontaminasi mikroba pada rempah dapat disebabkan oleh faktor lingkungan seperti suhu, kelembaban, kondisi sebelum dan pasca panen, serta kondisi tempat penyimpanan rempah tersebut. Tujuan dari penelitian ini adalah mengetahui tingkat sanitasi dan higiene pedagang rempah (kunyit, lada dan pala), menentukan total cemaran mikroba kontaminan, dan menentukan faktor intrinsik dan ekstrinsik yang dapat mempengaruhi cemaran mikroba pada rempah. Penelitian ini menggunakan metode survey yang dilakukan pada 2 pasar tradisional di kota Manokwari. Analisis data diolah menggunakan PCA (Principal Component Analysis). Hasil penelitian menunjukkan bahwa tingkat sanitasi dan higiene pedagang rempah di pasar tradisional kota Manokwari berada pada kategori kurang sampai cukup dengan persentase skor PSAT (Pangan Segar Asal Tumbuhan) 44-71% pada pasar Sanggeng, dan 44-65% untuk pasar Wosi. Pedagang di pasar Sanggeng dan Wosi dengan sanitasi tertinggi dikodekan sebagai ST dan WT sedangkan pedagang dengan sanitasi terrendah dikodekan sebagai SR dan WR. Rata-rata Angka Lempeng Total dan Angka Kapang Khamir untuk sampel kunyit dan pala dari pedagang ST, kunyit, lada, dan pala dari pedagang SR, lada dan pala dari pedagang WT dan WR, masih di bawah batas maksimum dari standar yang telah ditetapkan SNI 01-3709-1995. Sedangkan sampel lada dari pedagang ST dan kunyit dari pedagang WT dan WR, memiliki total bakteri TBUD (terlalu banyak untuk dihitung), artinya sudah melewati batas maksimum standar SNI 01-3709-1995 yaitu maksimal 106 CFU/g. Faktor intrinsik yang dapat mempengaruhi cemaran mikroba pada rempah adalah nilai aktivitas air dan kadar air, sedangkan faktor ekstrinsik yang dapat mempengaruhi cemaran mikroba adalah kelembaban relatif dan suhu lingkungan di pasar.

Abstract

ABSTRACT: Blood disease is a significant problem in Kepok banana cultivation, resulting in substantial economic losses. Blood disease is caused by the pathogenic bacteria Rastolnia syzygii subsp. celebecensis, a soil-borne disease. Soil microbes play a crucial role in the biocontrol process because they can produce certain enzymes or metabolites that can suppress disease-causing pathogens in plants. One approach is the use of fungi as antagonistic biological agents that can protect plants from disease attack. The presence of fungal biological agents in the rhizosphere of Kepok banana plants infected with blood disease requires isolation and identification of soil fungi to obtain data on the diversity of indigenous rhizosphere fungi in Kepok banana plants infected with blood disease in Bremi, North Manokwari District. The results of the isolation and identification of rhizosphere fungi in Kepok banana plants infected with blood disease yielded six (6) fungal isolates with high disease virulence and eleven (11) fungal isolates with moderate disease virulence. The fungal isolates obtained from the rhizosphere of high disease virulence were identified as Trichoderma sp1., Rhizoctonia sp., Aspergillus sp1., Aspergillus sp2., Trichoderma sp2., and Trichoderma sp3. Fungal isolates obtained from the rhizosphere of moderate disease virulence were identified as Fusarium sp1., Fusarium sp2., Penicillium sp1., Aspergillus sp1., Aspergillus sp2., Trichoderma sp1., Trichoderma sp2., Trichoderma sp3., Fusarium sp3., Penicillium sp2., and Penicillium sp3.
