Bacterial infections produce diseases such as Escherichia coli diarrhea, which is a big issue in developing countries. Clove flower (Syzygium aromaticum), Cinnamon bark (Cinnamomum verum), and Star anise (Illicium verum) contain active ingredients such as alkaloids, saponins, flavonoids, polyphenols, tannins, glycosides, and volatile oils which have potential as antibacterial. This study aims to analyze the difference in the inhibition zone of the extracts of the three plants extracted with 96% ethanol solvent against Escherichia coli using the disc diffusion method with extract concentrations of 15%, 20%, and 25%, and compare them with thiamphenicol as a positive control with the same concentration. The results show that the extracts have antibacterial activity that increases with the increase in concentration, where 25% concentration give the largest zone of inhibition. The clove extract has the highest inhibition, followed by cinnamon and star anise, although thiamphenicol remained the most effective. These findings confirm the significant antibacterial potential of all three extracts with α = 0,000.

Hydroponics, an emerging agricultural technology, allows cultivation without soil, but using nutrient-rich water instead. This is promising for future agriculture, as it can be applied in various locations and offers higher quality production results, thus increasing market competitiveness. In addition, waste materials such as rice washing water and goat urine can be reused as valuable organic fertilizers. Rice washing water, rich in nutrients such as vitamin B1, phosphorus, calcium, and nitrogen, serves as a liquid organic fertilizer that promotes superior plant growth. Goat urine, containing natural phytohormones, supports root and shoot development, making it a useful alternative to organic fertilizers. Research shows that liquid organic fertilizers are often preferred over synthetic options in hydroponic systems due to their higher bioactive compound content and environmental safety. This study focuses on the cultivation of Pak Choi (Brassica rapa var. Chinensis) using various nutrient treatments, including rice washing water, goat urine, and AB Mix, with measured concentrations ranging from 1000 to 1400 Part Per Millions (PPM). The results showed significant differences in growth among the treatment groups, with AB Mix producing the highest plant height, number of leaves, and leaf width, indicating the effectiveness of nutrient type on plant development.

Several types of aquatic plants are known to have the ability to improve water quality. The application of phytoremediation to domestic waste can significantly reduce Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), ammonia, nitrate, and phosphate levels, as well as increase dissolved oxygen (DO) levels in the water, thus improving water quality and making it suitable for aquatic organisms. This study investigated the efficacy of three aquatic plants Water Spinach (Ipomoea aquatica), Watercress (Nasturtium officinale), and Genjer (Lemna minor) in enhancing the quality of domestic wastewater. The experiment was conducted in a controlled environment at the Greenhouse facility of Universitas Advent Indonesia, utilizing seven containers stocked with domestic wastewater and catfish specimens. Treatments consisted of systems with and without the incorporation of these aquatic plants. Results demonstrated that all three plants significantly ameliorated water quality parameters, including reductions in Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS), alongside elevations in pH and Dissolved Oxygen (DO) levels. Notably, Ipomoea aquatica exhibited superior performance, yielding the highest catfish survival rates. These outcomes underscore the potential of integrating aquatic plants into aquaponic systems as aviable, environmentally sustainable approach to domestic wastewater remediation.

The rise of antibiotic resistance necessitates the discovery of new antibacterial agents. Sweet orange (Citrus sinensis) peel often considered waste, contains bioactive compounds with potential antimicrobial properties. This study aimed to evaluate the antibacterial activity of ethanol extracts from sweet orange peel on Escherichia coli, Shigella dysenteriae, and Salmonella typhii. This laboratory experimental study uses sweet orange peel extracted by maceration using 30%, 40%, and 50% ethanol as solvent. The highest average inhibition zones were observed at the 50% concentration for all bacteria: E. coli (7,683 mm), S. typhii (8,400 mm), and S. dysenteriae (7,250 mm). Statistical analysis confirmed that the extract concentration has a very significant effect (p = 0,000) on the inhibition zone, with higher concentrations yielding larger zones. A significant interaction was also found between the type of bacteria and time (p = 0,000). Ethanol extract of sweet orange (Citrus sinensis) peel has moderate antibacterial activity against Escherichia coli, Shigella dysenteriae, and Salmonella typhii. Its effectiveness is concentration-dependent, with the 50% ethanol extract shows the strongest inhibition. This suggests that orange peel waste is a promising source of natural antibacterial compounds.

Increasing antibiotic resistance against major pathogens like Staphylococcus aureus and Escherichia coli are necessitates as alternative antimicrobials. Curcumin, known for its antibacterial properties, suffers from low bioavailability; thus, developing it into nanocurcumin using the stabilizer PVP is aims in enhancing its efficacy. This study was conducted to investigate the effect of nanocurcumin particle sizes (controlled by three PVP K30 concentrations: 1.5, 3.0, and 4.5 g/mL) on its inhibitory potential on Staphylococcus aureus and Escherichia coli. The research is a true laboratory experimental design, synthesizing nanocurcumin via a Rotor Stator Homogenizer and assessing antibacterial activity using the disc diffusion method on Mueller Hinton Agar (MHA), with inhibition zone diameters are analyze using One-Way ANOVA. All tested samples exhibit weak inhibitory potential. The ANOVA revealed no significant effect against Staphylococcus aureus (p = 0.377), but shows a significant effect against Escherichia coli (p = 0.042). These finding shows that particle size variations of nanocurcumin influence against Gram-negative bacteria, with the smallest average particle size (20.6 nm) obtained at 1.5 g/mL PVP K30. In conclusion, nanocurcumin size variations significantly affect the inhibition against Escherichia coli but not against Staphylococcus aureus, a differential effect attributed to the distinct cell wall structures of the two bacteria types. Future studies are recommended to explore optimization methods to improve nanocurcumin's efficacy, especially against Staphylococcus aureus.

Excessive oil production, irritation, and bacterial infections, especially those produced by Staphylococcus aureus, are the main causes of acne, a common skin condition. The antibacterial qualities of a variety of therapeutic plants have long been utilized. This study aimed to evaluate the antibacterial effectiveness of ethanol extracts of Binahong (Anredera cordifolia), Aloe vera (Aloe vera), and Pegagan (Centella asiatica L.) leaves against the growth of Staphylococcus aureus. This research was a true experimental study using the Kirby-Bauer disk diffusion method. The ethanol concentrations used for extraction were 30%, 40%, and 50%, with meropenem as a comparison. The inhibition zones were measured after 24 hours of incubation at 37°C. The results showed that all extracts exhibited moderate antibacterial activity, with inhibition zones increasing along with higher extract concentrations. The highest mean inhibition zone was observed in Pegagan (8.9 mm), followed by Binahong (8.783 mm) and Aloe vera (8.26 mm). Statistical analysis showed that concentration (p = 0.005), day (p = 0.038), interaction between plant*day (p = 0.011), and plant*concentration*day (p = 0.001) have a significant effect on the inhibition zone diameter (p < 0.05). Meanwhile, plant (p = 0.244), interaction between plant*concentration (p = 0.380), and interaction between concentration*day (p = 0.342) show no significant differences in the inhibition zone diameter (p > 0.05). The conclusion is that there are differences in the inhibitory power of binahong, aloe vera, and pegagan plant extracts against Staphylococcus aureus bacteria used with 70% ethanol solvent.
