Abstract

Lakes are among the most complex aquatic ecosystems, as they support a wide variety of organisms. One of the organisms commonly found in lake ecosystems is the dragonfly (Order Odonata). Ecologically, dragonflies play important roles, including acting as predators in the food chain that help regulate insect populations and serving as bioindicators of water quality. The presence and diversity of dragonflies are closely related to environmental conditions, particularly water quality and surrounding vegetation. This study aims to examine the species diversity of dragonflies in the Tun Telanai Lake area at Jambi University. A descriptive quantitative method was employed, involving direct observation and identification of dragonfly species found in the study area. The results of the identification revealed the presence of three dragonfly families comprising a total of ten species. The family Libellulidae was the most dominant, represented by seven species, followed by the family Gomphidae with two species, and the family Coenagrionidae with one species. The calculation of the Shannon–Wiener diversity index (H’) yielded a value of 1.29, which falls within the moderate diversity category. This result indicates that the habitat conditions and aquatic ecosystem of Tun Telanai Lake are relatively stable and capable of supporting dragonfly populations.

Abstract

The community of Legok Raina Village in Bogor Regency, West Java, continues to rely on medicinal plants for daily healthcare practices. This study aimed to inventory and identify medicinal plant species and document the plant parts used, preparation methods, therapeutic functions, and ailments treated, as no previous research has been conducted in this area. Data were collected through semi-structured interviews with one traditional healer (tabib), two traditional birth attendants (paraji), and 27 general respondents selected by community leaders, complemented by plant specimen collection, observation, and documentation. The data were analyzed using the Use Value (UV) index to determine the relative importance of each species. A total of 104 species belonging to 93 genera and 46 families were recorded, with Zingiberaceae as the most dominant family, comprising 12 species from 8 genera. Shrubs represented the most common growth form (39 species), and leaves were the most frequently utilized plant part. Ageratum conyzoides showed the highest UV (1.760), whereas Lactuca sativa, Piper sarmentosum, and Kadsura scandens had the lowest (0.003). Approximately 60% of respondents continue to preserve ancestral knowledge and actively participate in conservation efforts. These findings highlight the cultural and therapeutic significance of traditional medicinal plants in the study area.

Abstract

This study investigated the morphological characteristics and abundance of bacteria and fungi isolated from fried snack foods and spoiled fruits. Bacterial isolates were obtained from bakwan, batagor, and stuffed tofu, while fungal isolates were recovered from spoiled mango, banana, and papaya. Culture-based methods were employed to characterize macroscopic colony morphology and to quantify microbial abundance using the Total Plate Count (TPC) method. The results revealed distinct dominance patterns across different food types. In fried snacks, isolates BKK3, BTK2, and STK5 exhibited the highest TPC values, reaching up to 10⁷ CFU/g, indicating substantial post-processing bacterial contamination. In contrast, spoiled fruits were predominantly colonized by fungal isolates MGK3, BNK3, and PPK4, with TPC values also reaching 10⁷ CFU/g. These fungal isolates displayed typical filamentous mold characteristics, including white-to-green mycelia, granular to rugose textures, and radial and concentric growth patterns. This comparative analysis within a unified study framework demonstrates that difference in food type and intrinsic characteristics-namely ready-to-eat processed products with high environmental exposure versus fresh fruit tissues rich in nutrients and simple sugars-shape contrasting microbial dominance patterns. Fried snacks were primarily dominated by post-processing bacterial contaminants, whereas spoiled fruits were characterized by saprophytic fungal predominance. These findings highlight the critical role of physicochemical properties and handling conditions in determining microbial community dynamics and provide a conceptual basis for microbiological risk assessment in street-vended and fresh food systems. Practically, the results underscore the importance of hygiene control and post-processing management to mitigate microbial hazards and potential mycotoxin risks.

Abstract

This study aimed to evaluate the antioxidant activity of the chloroform extract of clove leaves (Syzygium aromaticum) as a source of bioactive compounds. Unlike most previous studies that predominantly focused on essential oils or polar extracts of clove, this research specifically investigates the antioxidant potential of the semi-polar chloroform extract, which remains relatively underexplored. Extraction was performed using chloroform to obtain semi-polar compounds with potential biological activity. Phytochemical screening revealed the presence of phenolic compounds, flavonoids, tannins, and terpenoids, which are known to function as natural antioxidants. Antioxidant activity was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging assay based on the ability of the sample to neutralize free radicals. The results demonstrated an increase in percentage inhibition with increasing extract concentration, indicating a positive linear relationship between concentration and antioxidant activity. Linear regression analysis yielded an IC₅₀ value of 69.40 ppm, classifying the extract as having strong antioxidant activity. In comparison, ascorbic acid exhibited an IC₅₀ value of 8.75 ppm, indicating very strong antioxidant activity. This difference is attributed to the nature of ascorbic acid as a pure compound, whereas the chloroform extract consists of a complex mixture of secondary metabolites. The novelty of this study lies in highlighting the significant antioxidant potential of the semi-polar chloroform fraction of clove leaves, thereby expanding the understanding of solvent-specific bioactive compound distribution and providing new insight into its possible application in functional food and pharmaceutical development. Overall, the findings suggest that the chloroform extract of clove leaves has promising potential as a natural source of bioactive compounds for further development.

Abstract

Ethylene glycol is one of the toxic substances commonly used as solvents and is known to induce oxidative stress in neural tissue. GPX-3 is an antioxidant enzyme that works to reduce ROS, maintain redox balance, and protect cells from damage caused by free radicals produced during oxidative stress processes. This study aims to evaluate the effect of administering Moringa oleifera L. leaf extract after ethylene glycol induction on the intensity of GPx-3 gene expression in the brain of white rats (Rattus norvegicus). This research employed a completely randomized design (RAL) using 20 rats divided into five groups: a normal control group, a 0.75% ethylene glycol group, a 150 mg/kgBW Mo group, a 300 mg/kgBW Mo group, and a 450 mg/kgBW Mo group. The research stages included brain RNA extraction, cDNA synthesis, PCR amplification, agarose gel electrophoresis, and band intensity analysis using ImageJ. The results showed that GPx-3 gene expression in rat brain tissue appeared at 300 bp. Administration of Moringa oleifera L. leaf extract increased GPx-3 gene expression intensity in ethylene glycol induced rats, with the most prominent increase observed in treatment 2 (300 mg/kgBW). The increase or decrease in measured expression after normalization to GAPDH indicates that the observed changes reflect a biological response to treatment rather than technical error. This study presents a novelty finding by demonstrating, for the first time, the dose-dependent modulation of GPx-3 gene expression in brain tissue following ethylene glycol induced oxidative stress and identifying 300 mg/kgBW as the most effective dose, thereby revealing a potential molecular mechanism underlying the neuroprotective effect of Moringa oleifera L. leaf extract.

Abstract

Sea cucumber (Holothuria atra) has been traditionally used for wound treatment; however, scientific evidence supporting its effectiveness in burn wound healing remains limited. This study presents a novel investigation of the wound healing potential of H. atra extract sourced specifically from the Talaud Islands and formulated into multiple topical ointment concentrations for second-degree burn treatment. The study aimed to evaluate the effectiveness of H. atra extract ointment in accelerating second degree burn wound healing in mice. The extract was obtained by maceration using 95% ethanol and formulated into ointments at concentrations of 10%, 15%, and 20%. Twenty-five male mice were randomly assigned to five groups: positive control (1% silver sulfadiazine), negative control, and three treatment groups receiving H. atra extract ointments at different concentrations. Parameters observed included wound diameter reduction, physical characteristics of the ointment, phytochemical screening, and pain-related behavioral responses. The results demonstrated that the 15% H. atra extract ointment produced the highest wound healing effectiveness, with a wound contraction rate of 96% on day 14, followed by the 10% (84%) and 20% (75%) formulations. Phytochemical analysis revealed the presence of flavonoids, saponins, steroids, and alkaloids, which are associated with anti-inflammatory, antimicrobial, and tissue regenerative activities. The ointment formulations met homogeneity and organoleptic requirements, although their spreadability values were below the recommended standard. These findings highlight the novelty of identifying an optimal concentration (15%) of H. atra extract ointment that provides superior burn wound healing activity compared with other tested concentrations. In conclusion, the 15% H. atra extract ointment shows potential as an alternative topical therapy for second-degree burn wounds.
