Abstract

The research aims to document and analyze the ethnobotanical utilization of food crops within the Saur Matua traditional ceremony of the Toba Batak tribe in Nainggolan District, Samosir Regency. Utilizing a qualitative descriptive approach, data were collected through semi-structured interviews with fourteen informants and field observations in Sibonor Ompu Ratus and Sinaga Uruk Pandiangan villages. The study identified 26 species of food plants belonging to 17 families, with Zingiberaceae, Solanaceae, and Amaryllidaceae being the most dominant. The findings reveal that the fruit is the most frequently utilized plant part, while the herb habitus is the most common growth form. These plants are primarily processed as cooking spices for traditional dishes like dekke arsik and saksang, as well as ceremonial snacks like lapet. Beyond nutritional value, these plants carry profound philosophical meanings; for instance, eme (rice) symbolizes prosperity and life continuity. The study concludes that while the Saur Matua ceremony remains a vital cultural pillar, there is a growing dependency on commercial markets for ritual plants due to declining local cultivation. This documentation serves as a crucial effort in preserving the traditional ecological knowledge and cultural identity of the Toba Batak community against the pressures of modernization.

Abstract

Tanah Sareal District is an urban area with a high level of urbanization and land conversion, potentially reducing the presence of conservation-value vegetation. This study aims to identify, analyze, and map the distribution of urban vegetation with conservation value using a Geographic Information System (GIS)-based spatial approach. The research method uses a descriptive quantitative approach through field surveys, Landsat 8 and Sentinel-2 image analysis, Normalized Difference Vegetation Index (NDVI) analysis, and overlay techniques, kernel density, and vegetation fragmentation analysis. The results show that more than two-thirds of the area is dominated by built-up areas, while high-density vegetation (NDVI > 0.5) is only found in limited areas such as river banks, green open spaces, and educational areas. The identified conservation-value vegetation includes Tanjung (Mimusops elengi), Kecapi (Sandoricum koetjape), Beringin (Ficus benjamina), Bisbul (Diospyros blancoi), and Pulai (Alstonia scholaris), with a fragmented distribution pattern. This study shows that GIS-based digital mapping effectively supports vegetation conservation planning and strengthens green open spaces in urban areas.

Abstract

Coral reef degradation in coastal areas reduces habitat quality and alters the communities of reef fish structure. This study aimed to compare the structure of reef fish communities between coral transplantation sites using the spider web method and non-transplantation sites in the waters of Labuan Village, Tojo Una-Una Regency, Central Sulawesi. Observations were conducted three times applying the Underwater Visual Census (UVC) method along 50 m² transects. The analyzed parameters included the diversity  index (H’), evenness (E), dominance (D), abudance index, composition of the number and families of reef fish and water quality indicators such as temperature, pH, salinity, dissolved oxygen, water transparency, depth. The results showed that the transplantation site had higher diversity (H’ = 3.62–3.69), stable evenness (E = 0.99–1.00), low dominance (C = 0.026–0.027), and Reef fish higher abundance compared to the non-transplantation site (3.30-5.98). An independent samples t-test indicated significant differences (p < 0.05) in diversity, evenness, dominance, and abundance of reef fish between the coral transplantation and non-transplantation sites. It was determined that the spider web method of coral transplantation was effective when supported by appropriate water quality in increasing the stability community of reef fish

Abstract

Phytoplankton are primary producers that respond rapidly to environmental changes and therefore have considerable potential as bioindicators of aquatic ecosystem conditions. This study aimed to analyze the abundance and community structure of phytoplankton and evaluate their ecological significance as bioindicators in the Uram River, Lebong Regency, Bengkulu Province. Sampling was conducted at four stations representing different habitat characteristics along the river continuum, including upstream, dam-influenced, settlement-associated, and downstream segments. Phytoplankton samples were collected using a plankton net and identified microscopically. Community analysis included abundance, Shannon-Wiener diversity, evenness, and dominance. A total of 52 phytoplankton species belonging to eight classes were identified, with Bacillariophyta as the dominant group, contributing 46.2% of the total species composition. The highest abundance was recorded at Station I (2,316.6 ind/L), while the highest diversity index was observed at Station III (H' = 3.380). High evenness values (0.855–0.898) and low dominance values (0.072–0.097) indicated a relatively stable community structure. Variations in phytoplankton composition among stations reflected differences in habitat conditions influenced by flow velocity, substrate characteristics, riparian vegetation, and human activities. These findings demonstrate that phytoplankton are effective bioindicators for assessing ecological conditions and provide baseline information for aquatic resource management and biomonitoring programs in the Uram River.

Abstract

Vaccination remains the primary strategy for controlling infectious diseases, yet the move to highly purified antigens requires the development of effective adjuvants to boost immunogenicity. Synthetic adjuvants often face limitations due to side effects and production costs, creating interest in natural bioactive compounds from local biodiversity. This study aims to explore and map the potential of local plants as sources of vaccine adjuvants using an integrative field-and-bioinformatics approach. Direct field exploration and morphological identification were conducted on 41 local plant species. This was integrated with a systematic meta-analysis of bioactive profiles and phylogenetic analysis to evaluate the evolutionary distribution of adjuvant candidates. The analysis identified 10 different classes of bioactive compounds across the surveyed flora. Flavonoids appeared as the most common type found in 20 species, followed by alkaloids which found in 6 species, while terpenoids, triterpenoids, and phenolics were respectively identified in 3 species. Other identified compounds included tannins, saponins, iso-flavonoids, steroids, and naphthoquinones. Phylogenetic mapping revealed that these potential adjuvants are distributed across 23 botanical families, showing that these local plants have evolved to posses diverse immune-boosting compounds. The diversity of bioactive compounds, particularly the predominance of flavonoids, highlights the significant potential of local flora for future vaccine formulation. Utilizing these indigenous resources can enhance local vaccine production capabilities and improve global vaccine accessibility.

Abstract

This study aimed to describe the plant and animal species utilized in the traditional rituals of the Rejang ethnic community and to calculate their Use Value (UV) indices. The research employed both qualitative and quantitative approaches. Qualitative data were collected through participant observation, in-depth interviews, and literature review. Respondents were selected using a purposive sampling method, while quantitative data were analyzed using the Use Value (UV) index to determine the relative importance of each species. The results showed that the Rejang community in Talang Rasau Village utilizes 24 plant species belonging to 17 families and 2 animal species belonging to 2 families in their traditional rituals. The plant species with the highest utilization were coconut (Cocos nucifera L.) and sedingin (Kalanchoe laciniata L.), each being used in 3 out of 6 traditional rituals and having a Use Value (UV) of 0.5. Among the animal species, goat (Capra aegagrus hircus) had the highest utilization, being used in 3 out of 6 traditional ritual activities with a Use Value (UV) of 0.5. These findings confirm that the frequency of a species’ use in traditional rituals is directly proportional to its Use Value, indicating that species used more frequently tend to have higher UV scores.

Abstract

Tahura Pancoran Mas, located in Depok City, West Java Province, is Indonesia's first nature reserve and constitutes a critical area for ecological research. Despite its significant ecological role, detailed data on tree diversity and Leaf Area Index (LAI), which represents canopy density, have not been systematically recorded across its management zones, namely the Protection Zone, Utilization Zone, and Collection Zone. This study aimed to analyze tree diversity and canopy density (LAI) across these three zones. Tree diversity data were collected using a modified transect line method consisting of nine plots, each measuring 20 × 20 meters. Canopy structure was recorded using digital hemispherical photography, tree species diversity was measured using the Shannon-Wiener index (H'), and LAI values were processed using the Hemiview software. A total of 81 individual trees were recorded, representing 20 species belonging to 13 families. Dominant species were identified in each zone: Artocarpus elasticus Reinw. ex Blume in the Protection Zone, Arenga pinnata (Wurmb) Merr. in the Utilization Zone, and Sandoricum koetjape (Burm.f.) Merr. in the Collection Zone. Biodiversity evaluation revealed that the mean Shannon-Wiener index across all three zones fell within the moderate category (Protection Zone H' = 2.20; Utilization Zone H' = 1.75; Collection Zone H' = 2.35). LAI results indicated that canopy density was classified as very dense, with values of 2.89, 2.92, and 2.84 in the protection, utilization, and collection zones, respectively. These findings may serve as a scientific reference for developing sustainable management strategies for the Tahura Pancoran Mas area, including planting native tree species appropriate to the ecological conditions of the Utilization Zone, environmental education programs, and periodic vegetation monitoring.
