This research was conducted on Jalan Tampok, Tanjung Selamat Village, Sunggal District, Deli Serdang Regency, North Sumatra. A non-factorial Randomized Block Design  was used, consisting of only one factor, with five treatments and four replications: 0, 1, 2, 3, and 4 liters of coconut water fertilizer. The results showed that the use of coconut water fertilizer had no significant effect on plant height 1, 2, and 3 weeks after planting, and fruit weight per plot. However, it had a highly significant effect on plant height 4 and 5 weeks after planting, stem diameter, number of leaves, and root length.   In general, increasing the dosage of coconut water POC tends to result in a better growth response during the vegetative phase of the plant. This suggests that the natural hormones in coconut water can support plant cell division and elongation. However, plant response to treatment is still influenced by environmental factors and dosage, so not all parameters show a significant effect. Further research is needed to determine the optimal dosage that is more effective on production yields.

Orthosiphon stamineus Benth., commonly known as kumis kucing, is a widely recognized medicinal herb in traditional medicine, particularly valued for its diuretic properties. This study aims to evaluate the potential of active compounds in O. stamineus as diuretic agents through an in silico approach using molecular docking methods. A total of 98 compounds were screened against three diuretic target receptors: 1Z9Y (furosemide receptor), 3HS4 (acetazolamide receptor), and 3VHU (spironolactone receptor). The docking results revealed that lithospermic acid I, dicaffeoyl tartaric acid, and orthosiponone C exhibited lower binding energies compared to standard ligands, indicating higher affinity and stronger molecular interaction stability. Molecular visualization showed that these compounds formed specific interactions, such as hydrogen bonds and π-π stacking, resembling the binding mechanisms of synthetic diuretics. This study highlights the significant potential of O. stamineus to be developed into a natural diuretic phytopharmaceutical. However, further validation through in vitro and in vivo studies is necessary to confirm their efficacy and safety in complex biological systems.    

Halitosis, or bad breath, is a multifactorial condition that is often caused by anaerobic bacterial activity in the oral cavity, especially on the dorsum surface of the tongue. The use of natural ingredients as an alternative halitosis treatment is a concern, one of which is the nutmeg plant (Myristica fragrans), which has various active compounds such as essential oils, saponins, flavonoids, and alkaloids. This study aims to assess the potential of nutmeg plants in inhibiting the growth of bacteria that cause halitosis through a literature review of 30 national and international journals within the last five years. The results showed that nutmeg extracts, both from seeds, pulp, and leaves, have antibacterial activity against various types of halitosis-causing bacteria such as Streptococcus mutans, Staphylococcus aureus, and Escherichia coli. This activity is obtained through the mechanism of cell membrane damage and inhibition of bacterial cell wall synthesis by bioactive compounds in nutmeg plants. Therefore, nutmeg has potential as a natural antibacterial agent in the management of halitosis.

Fertilizer is an important factor in increasing the growth and yield of chili plants (Capsicum annuum L.). The selection of the right type of fertilizer greatly determines productivity and environmental sustainability in the long term. This study aims to analyze the differences between chemical fertilizers and organic fertilizers in chili plant cultivation, including plant growth, yields, and their impact on soil fertility. The method used is a literature review by examining various previous studies that discuss the effectiveness of both types of fertilizers. The results of the analysis show that chemical fertilizers provide faster growth and higher yields in the short term because their nutrients are more easily absorbed by plants. However, excessive use can cause soil degradation, decreased organic matter content, and environmental pollution. In contrast, organic fertilizers work more slowly, but are able to increase soil fertility, improve soil structure, and support the balance of agricultural ecosystems in the long term. The combination of chemical and organic fertilizers has proven to be the best strategy in increasing chili productivity while maintaining soil health. Therefore, balanced fertilization with the right dose is highly recommended to ensure optimal harvest results without damaging the environment.

One alternative to increase plant growth and improve soil quality sustainably is organic fertilizer. Based on previous studies, this study discusses how organic fertilizer affects plant growth and soil quality. The results of the study indicate that organic fertilizer can increase plant growth by providing nutrients gradually and supporting the activity of soil microorganisms responsible for decomposing organic matter. The use of organic fertilizers has also been shown to improve soil structure, increase water retention capacity, and enrich it. However, there are several obstacles when using organic fertilizers, such as longer decomposition times and inconsistent nutrient levels. Therefore, efforts to optimize the use of organic fertilizers must be carried out continuously to increase their capacity to support sustainable agriculture.
