Abstract

Background: Phalaenopsis amabilis, or the moon orchid, is a popular type of orchid with high market demand. Planting media is a factor that can be successful in caring for the Phalaenopsis amabilis, which is an epiphytic orchid type or attaches to other plants. Most orchid planting techniques have not been adapted to their natural habitat in nature that attaches to other plants. The planting medium generally used for epiphytic orchids such as Phalaenopsis amabilis is fern boards, which are limited in nature. Researchers see the potential for coffee wood. Many can be used as a planting medium for Phalaenopsis amabilis because this plant is also found growing naturally in coffee plants. Methods: The research used comparative studies between coffee sticks and fern boards as planting media for Phalaenopsis amabilis on their vegetative growth according to their natural habitat by attaching to other plants. The analysis results were obtained by statistical tests t–test unpaired) using SPSS. Results: The analysis showed p ≤ 0.05 on the four parameters of Phalaenopsis amabilis growth. There are differences in the use of planting media types of coffee logs (M1) and fern boards (M2) on the vegetative growth of Phalaenopsis amabilis orchid plants, including the number of leaves, leaf span, leaf width, and root length. Conclusions: The vegetative growth on M1 and M2 is significantly different. The fern board planting media (M2) tends to be more recommended for use. After all, it can be optimal in providing vegetative growth consisting of the number of leaves, leaf span, leaf width, and root length because its growth is more stable.

Abstract

Background: Acrolejeunea fertilis (liverwort) is known for having various potential natural products. However, its abundance is limited, and its secondary metabolites have not been extensively investigated. The in vitro culture technique might enhance its biomass. Methods: This study aimed to investigate the metabolite profile of A. fertilis from Kebun Raya Cibodas grown in situ and in vitro. The bioactivity, including antioxidant, total phenolic, and flavonoid content and antibacterial activity, was also evaluated. The in vitro culture of A. fertilis used ½ MS media with the addition of 0,1 mg/L of 2,4-D and one mg/L of Kinetin. Methanol and n-hexane were used for extraction. Gas Chromatography-Mass spectrometry (GC-MS) is used for metabolite profiling. Results: The optimum IC50 value from n-hexane extract is 68,18±2,65 mg/L. The highest yield of total phenolic and flavonoid content from in situ methanol extract, which resulted in 130,68±0,002 µgGAE/gr and 5,97±0,01 µgQE/gr, respectively. Antibacterial activities were evaluated by measuring the zone of inhibition for S. aureus and E. coli. The optimum area measured from in situ n-hexane extract was 23,91±1,54 and 13,08±0,23 cm, respectively. Conclusions: These findings carry important implications for the further development of natural products obtained from liverwort regarding its potential as a bioactive compound.

Abstract

Background: Indonesia's biodiverse microalgae, numbering 2060 species, thrive in diverse environments, offering potential in pharmaceuticals, cosmetics, fuel, and heavy metal bioremediation. Lead pollution from mining poses risks, prompting stringent government contamination limits. Microalgae-based bioremediation, notably Chlamydomonas reinhardtii and Chlorella vulgaris removing up to 90% of lead, suggests further exploring Indonesia's microalgae diversity. Methods:  Data sourcing (2013-2023) employed Google and Google Scholar using specific keyword combinations across Indonesian provinces. Seventy-eight sources underwent analysis and visualization via Microsoft Excel 2021. Results: Microalgae's potential as lead bioremediation was explored across classes like Chlorophyceae, Cyanophyceae, and Bacillariophyceae. Chlorophyceae, exemplified by Chlorella and Scenedesmus, exhibit varied cell sizes and complex cell walls, aiding metal ion binding. Cyanophyceae like Cyanospira capsulata and N. commune synthesize diverse EPS compositions, indicating their potential in lead remediation. Conclusions: Indonesia's microalgae diversity across habitats, especially in the Chlorophyceae and Cyanophyceae classes, suggests a significant role in lead bioremediation. Their adaptability and diverse compositions highlight their potential for sustainable practices in combatting environmental lead contamination.

Abstract

Background: Exopolysaccharides (EPS) production gain a lot of attention over recent decades, because EPS can provide beneficial effects, not only on the industrial application but also on the health sector. The understanding of the optimal condition for EPS production will increase the productivity of EPS and can develop EPS with desirable properties. The factors affected EPS production are additional of sugar concentration, temperature, fermentation time, and others. The current work aimed to optimize the utilization of a byproduct leftover of coconut water on the EPS production from Lactobacillus fermentum. Methods: The EPS synthesis were analyzed under various growth conditions in coconut water such as additional of sucrose concentration and incubation times. EPS production of Lactobacillus fermentum was performed by adding 1%, 2%, and 3% of sucrose and 12, 24, 36, and 48 h of incubation periods. The obtained data were analyzed statistically using a two-ways ANOVA test. Results: The EPS production increased as the sucrose concentration and incubation time were increased. The optimal production was found to be in the media supplemented with 3% sucrose and 48 h of incubation period, which gave 12.613 g/L of EPS production. Conclusions: Media of coconut water is suitable for EPS production by Lactobacillus fermentum. Under 3% of additional sucrose concentration and 48 h of incubation time, it produced a larger number of EPS compare to other conditions.
