Abstract

Bacterial infection is a major cause of chronic infection and death that continues to threath public health worldwide. Improper use of antibiotics can cause pathogenic bacteria to become resistant to antibiotics and have side effects, so alternative sources of antibiotics from natural ingredients are needed. One type of plant that is efficacious as an antibacterial is jarak pagar leaves (Jatropha curcas). This study aims to examine the phytochemical content qualitatively using the tube method and the antibacterial activity of the ethyl acetate fraction of jarak pagar leaves using the disc diffusion method. Extraction of jarak pagar leaves by maceration method with 96% ethanol then fractionated with ethyl acetate. Data on the diameter of the inhibition zone in the antibacterial test were analyzed using the non-parametric test, namely the Kruskal Wallis test. The analysis was continued with Mann Whitney's post hoc with a confidence level (pvalue<0.05). Based on the results of the phytochemical test obtained alkaloids, saponins, flavonoids, polyphenols and tannins. The antibacterial activity of the ethyl acetate fraction of jarak pagar leaves at a concentration of 8 mg/mL showed an inhibition zone of 19.73±0.25 mm which was included in the very moderate category and weakly inhibited at a concentration of 0.5 mg/mL which was 4.87±0.31 mm and the results of statistical tests showed that the ethyl acetate fraction of jarak pagar leaves had antibacterial activity and each concentration had a significant effect on inhibiting the growth of S. aureus.

Abstract. Neneng L, Nawan, Naibaho FG, Rahman S, Septya L, Panjaitan D, Lestari RW, Irsyam ASD, Norwahyunie, Noraini. 2025. Botanical survey of ethnomedicines in Dayak sub-ethnic groups, Ot Danum and Tomum in Central Kalimantan, Indonesia. Biodiversitas 26: 458-469. The rise of globalization, urbanization, and environmental changes has led to the emergence of new infectious diseases and increased Antimicrobial Resistance (AMR), posing significant public health threats. This study aims to document the traditional medicinal knowledge of the Dayak Ot Danum and Tomum subtribes in Central Kalimantan, Indonesia, particularly regarding their ethnobotanical remedies for treating infectious diseases. Field surveys were conducted in August 2024 across four villages, utilizing purposive and snowball sampling techniques to interview 12 key informants, including traditional healers. Semi-structured interviews, Focus Group Discussions (FGD), and field observations were employed to gather information on the local use of medicinal plants. A total of 62 plant species were identified, with the highest proportions targeting bacterial infections (24 species), followed by viral (21 species), fungal (11 species), and parasitic infections (4 species), with mixed efficacy as antibacterial and antifungal (10 species) and antibacterial and antiviral (3 species). The Zingiberaceae family was the most frequently documented, a testament to the diverse and rich ethnobotanical knowledge of these communities. The findings highlight the effective use of traditional medicine in combating infections, suggesting the potential for integrating ethnobiological practices into contemporary healthcare strategies to address AMR. As indigenous populations face increasing health risks, preserving and leveraging traditional medicinal knowledge is crucial for developing sustainable approaches to health and wellness.

Abstract

This study presents a flow-rate-regulated co-precipitation method for synthesizing ZnO nanoparticles using a peristaltic pump to enhance control over nucleation and growth processes. The primary objective was to investigate the effect of controlled reactant delivery on the structural and morphological properties of ZnO nanoparticles. A peristaltic pump system was calibrated to provide a stable and continuous flow of the precipitating agent, achieving an average flow rate of 93.39 ± 1.39 µL/s with high linearity (R² = 0.99946). ZnO nanoparticles were synthesized under controlled conditions and characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results confirmed the formation of a single-phase hexagonal ZnO structure with high crystallinity and an average crystallite size of 55.98 ± 8.35 nm. SEM analysis revealed the formation of nanorod structures with relatively uniform morphology. The improved uniformity is attributed to stable supersaturation conditions enabled by precise flow-rate control. These findings demonstrate that flow-rate regulation is a critical parameter in co-precipitation synthesis and offers a simple, cost-effective strategy for improving reproducibility and structural control in nanoparticle fabrication.
