Abstract

The Baccaurea brevipes Hook.F. plant has been studied in the past and has the potential to be a therapeutic herb. The Tampoi plant (B. brevipes) has been used as a medication by the Acehnese to regulate menstruation and make urinating easier. In nature, endophytic fungi are widespread and can be easily found in plant tissue. Without infecting the host plant, the endophytes colonize the inter and intracellular spaces of the tissue. Endophytic fungi can create bioactive chemicals that may be similar to or distinct from those of their host plants and have pharmacological effects. However, no studies have been done on its endophytic fungus as a potential source for novel medication development. This study was done to look into endophytic fungi in Baccaurea's twigs and roots. The techniques employed in this study were endophytic fungi purification, identification of macroscopic and microscopic endophytic fungi, and endophytic fungi isolation. Five isolates were identified as a result of isolation and purification; they were designated as isolates BVA1, BVA2, BVA3, BVR1 and BVR2. The genera Neofusicocum sp., Colletotrichum sp., Mucor sp., Fusarium sp. and Schizophyllum sp. are assumed to be the kind of endophytic fungal isolates BVA1, BVA2, BVA3, BVR1 and BVR2.

Abstract

Pollinator insects are insects that play a role in the pollination process, namely intermediaries in plant pollination. Magnolia spp plants are plants that contain secondary metabolite compounds which have the potential to be used as raw materials for medicines, cosmetics and perfume raw materials. The aim of this research was to determine the diversity and abundance of insect pollinators and flower visitors on Magnolia spp. at Universitas Samudra. The method used in this research is sampling using a purposive random sampling method with hand collecting techniques, identification and data analysis.The research results found 9 orders and 5 families from 139 individual insect pollinators and pollinators on Magnolia spp. The results of data analysis show that the H' value (1.72) is in the medium category, the C value (0.23) has low dominance, and the E value (0.19) shows low uniformity. Several factors influence the presence of pollinator insects and flower visitors, including flower availability, temperature and air humidity.

Abstract

Ageratum conyzoides L. and Adenostemma lavenia are known to contain bioactive compounds with potential therapeutic properties. This study aimed to determine the phenolic and flavonoid contents, as well as the toxicity of leaf extracts from both species against Artemia salina larvae. The extraction process was carried out using methanol as a solvent. Phenolic content was measured using the Folin-Ciocalteu method, while flavonoid content was determined through a colorimetric method using aluminum chloride (AlCl₃) reagent. Toxicity testing was performed using the Brine Shrimp Lethality Test (BSLT) method. The results showed that the methanolic extract of Ageratum conyzoides L. contained 173 mg GAE/g extract of phenolics and 55.45 mg QE/g extract of flavonoids, which were higher than those found in Adenostemma lavenia, with 73.8 mg GAE/g extract of phenolics and 6.33 mg QE/g extract of flavonoids. Toxicity test results analyzed using probit analysis revealed LC₅₀ values of 43.17 μg/mL for Ageratum conyzoides L. extract and 208.07 μg/mL for Adenostemma lavenia extract, indicating that both are toxic. Based on these findings, it can be concluded that Ageratum conyzoides L. possesses greater potential as a source of bioactive compounds, as indicated by its higher toxic activity. Both plants are considered worthy of further investigation as potential anticancer agents.

Abstract

Indonesia is rich in biodiversity and traditional knowledge related to the use of medicinal plants. This study aims to document medicinal plant species used by the Dayak Kenyah community in Punan Gong Solok Village, North Kalimantan, and to describe their utilization patterns based on local ethnomedicinal practices. A qualitative descriptive method was employed, involving interviews, participatory observations, and plant identification. Data were collected using snowball sampling for informants and purposive sampling for plant exploration. The results revealed 46 species from 25 families used in traditional medicine, dominated by the Zingiberaceae and Araceae families. Leaves were the most commonly used plant part (33.3%), followed by tubers, roots, and stems. The plants were used to treat stomachaches, gastritis, kidney stones, external wounds, and respiratory disorders, with preparation methods including boiling, pounding, and infusion. These findings highlight the importance of preserving local knowledge as a basis for developing phytopharmaceuticals and promoting community-based conservation.

Abstract

Sibutramine hydrochloride is a chemical compound that was once often used as a weight loss drug. This drug is hazardous if used illegally in herbal medicine because it can cause health problems such as kidney failure, heart attacks, and strokes. BPOM has banned its use in herbal medicine, but until now herbal medicine containing sibutramine hydrochloride is still on the market. This study aims to determine the levels of Sibutramine Hydrochloride contained in slimming herbal medicine. The samples used in this study consisted of four brands of slimming herbal medicine that are not registered with BPOM, coded A, B, C, and D, which were obtained from several shops in Baiturrahman District, Banda Aceh City. Sampling was carried out using the total sampling method and then analyzed quantitatively using UV-Vis spectrophotometry. The results of the analysis showed that the four samples were positive for containing Sibutramine Hydrochloride with an average level of 31.69% of herbal medicine sample A; 39.88% of herbal medicine sample B; 7.09% of herbal medicine sample C; and 36.60% of herbal medicine sample D. Therefore, stricter examination and supervision of the circulation of slimming herbal medicine products in the Banda Aceh city area are needed to protect public health.

Abstract

Palm plants (Arenga pinnata) are a type of palm plant that has high economic value in Indonesia, including in South Tapanuli Regency. All parts of the palm plant, ranging from sap, fruits, leaves, to stems have various benefits. However, in its cultivation, palm plants often face disturbances from insects, both as pests and as pollinating agents that have an important ecological role. Therefore, this study aims to inventory the types and populations of insects associated with palm plants in order to understand insect diversity and identify potential pests and natural predators. This study was conducted in Pargarutan Dolok Village, East Angkola District, South Tapanuli Regency for eight weeks using the anthracane trap method and direct observation. The results showed that insects of the order Hymenoptera, especially the family Apidae, were the group with the highest number of anthracite traps, at 23 individuals. In total, 65 individual insects were found consisting of 6 orders and 10 families. The insect population during the 1st to 4th week was 40 individuals, while in the 5th to 8th week it was 25 individuals. The role of insects found in palm plants includes pollinators, predators, and polyphages.

Abstract

This study was conducted to document and to describe the diversity of plant species along the trail of the Botanical Forest Park (Tahura) in North of Sumatra. The research employed an exploratory survey method using a transect approach, with species identification based on observable morphological characteristics in the field. Observations recorded a total of 114 plant species categorized as cultivated or agricultural plants, predominantly found in areas near settlements. In contrast, within zones of natural vegetation, 106 plant species were identified, distributed across 48 different families. These findings reflect a high level of floral diversity in Tahura Medan area, encompassing both native vegetation and cultivated species. Such biodiversity is not only essential for supporting environmental conservation efforts but also holds strategic value as a resource for tropical ecology education, particularly within urban settings.
