Abstract

Honey bees (Apis spp.) play a crucial role in maintaining ecosystem balance through pollination, which directly impacts the sustainability of biodiversity and human food security. Studies on the antagonistic interactions between Apis cerana and Vespa sp. are still relatively limited in Indonesia, particularly in conservation areas such as Tahura Djuanda. This study aims to observe the disruptive factors of Vespa sp. wasps, a natural enemy of the Apis cerana honey bee in Tahura Djuanda. The methods used were direct field observation and recording of Vespa sp. activity on bee colonies. The seven-day study showed that disruption by Vespa sp. wasps on the foraging activity of Apis cerana bees occurred with high frequency. The average number of Vespa sp. presence per day in insect tubes installed in calliandra flowers reached 23,28 individuals, significantly higher than the control of 3,43 individuals per day. This disturbance caused a significant decrease in bee foraging activity, increased defensive behavior, and the potential for colonies to abandon the nest (absconding). This study confirms that Vespa sp. is a natural enemy that can reduce the activity and productivity of Apis cerana colonies, and that control strategies are needed to minimize its impact.

Abstract

This research explores the utilization of goat urine as the main ingredient in the production of Liquid Organic Fertilizer (LOF), enhanced with herbal additives (empon-empon) as natural fermentation starters. The study aims to provide an environmentally friendly and sustainable alternative to chemical fertilizers by transforming goat farming waste into productive agricultural input. Two herbal starter formulations were developed using ingredients such as ginger, turmeric, papaya leaves, sprout extract, and coconut water. These formulations were applied to Odot grass (Pennisetum purpureum cv. Mott) as the test crop over a 30-day period. Growth parameters including plant height, number of leaves, fresh weight, and dry weight were measured and statistically analyzed using Independent Sample T-Test. The results showed no significant differences between the two treatments across all measured variables, although starter A showed a slightly higher average performance in fresh and dry biomass production. The findings suggest that both formulations of LOF are viable and contribute to sustainable agricultural practices by improving soil fertility and promoting healthy plant growth through natural inputs.

Abstract

Hypertension, one of the most common chronic non-communicable diseases, is often undetected and has become a leading cause of mortality worldwide. This worry emphasizes how crucial it is to carry out this inquiry. This study sought to ascertain the association between the level of medication adherence and the knowledge and attitude of hypertension patients at Tanjung Karang Public Health Center. This study used a cross-sectional methodology, purposive sampling, and a correlational analytical design. Correlational analysis was done on the 51 respondents that made up the sample. A validated questionnaire was used to gather data, and the Statistical Program for the Social Sciences (SPSS) was used to evaluate the results using the Spearman's Rho test. The majority of respondents were over 45 years old (72.55%), male (52.94%), had completed senior high school (35.29%), and worked as fishermen, farmers, or housewives (56.86%). Most respondents had low levels of knowledge (94.12%) and a positive attitude toward treatment (68.63%). The majority had a moderate level of medication adherence (82.35%), with no respondents categorized as having low adherence (0%). The test results showed no significant relationship between attitude and adherence (r = 0.134; p = 0.347), and no significant relationship between knowledge and adherence (r = -0.009; p = 0.951).

Abstract

High-sensitivity C-reactive protein (hs-CRP) levels are inflammatory markers that can be influenced by visceral adipose tissue, especially since sex hormones also influence fat storage patterns and the incidence of central obesity. This study examined the relationship between waist circumference and hs-CRP levels in men. This study used an analytical observational study type with a cross-sectional approach. Statistical analysis of 24 samples using the non-parametric Rank-Spearman test obtained a significance value (p < 0.05); r = 0.763. This study shows a significant relationship between men's waist circumference and Hs-CRP levels. Further research can pay attention to variables that can increase Hs-CRP levels, such as physical activity, food intake, other infectious diseases, and examination of blood glucose, cholesterol, and blood pressure levels.

Abstract

The green planthopper (Nephotettix virescens) is a major pest that significantly disrupts rice production by transmitting grassy stunt and empty grain viruses. This research aims to develop an effective botanical pesticide from Kuit lime (Citrus amblycarpa) and Gelinggang (Cassia alata) leaf extracts to control green planthopper populations. The study employed an experimental method with three treatment groups: Kuit lime leaf extract, Gelinggang leaf extract, and a combination of both, alongside a chemical pesticide as the control. Mortality rates of green planthoppers were recorded and analyzed. The results showed that the combined extract had the highest efficacy with a mortality rate of 97.5%, followed by Gelinggang extract (85%), and Kuit lime extract (82.5%). The chemical pesticide achieved 100% mortality. The study concludes that the combined extract of Kuit lime and Gelinggang leaves is a highly effective botanical pesticide against N. virescens. This finding supports the use of environmentally friendly plant-based insecticides as a sustainable alternative to synthetic pesticides. Further research is recommended to explore field-scale application and long-term effects on non-target organisms.

Abstract

Peripheral neuropathy is a peripheral nerve disorders involving sensory, motor, or mixed nerves. First-line therapies for peripheral neuropathy, such as analgesics and SSRIs, often yield suboptimal therapeutic responses, have side effects, and provide inadequate disease control. Therefore, there is a need for adjuvant therapy utilizing bioactive compounds from natural sources, one of which is marine algae. Marine algae contain various compounds that have the potential to serve as safe and effective alternative adjuvant therapies for peripheral neuropathy. The literature used was collected from the PubMed, ScienceDirect, and Google Scholar databases with restrictions: publication years from 2015 to 2025 and in either Indonesian or English. The review indicated that several compounds found in marine algae, such as florotanins, terpenoids, polysaccharides, peptide proteins, essential amino acids, and omega-3 fatty acids, exhibited biological activities such as antioxidant, anti-inflammatory, and neuroprotective effects. These compounds showed potential as alternative adjuvant therapies for peripheral neuropathy. In conclusion, the compounds in marine algae demonstrated various biological activities, suggesting their potential for development as alternative adjuvant therapies for peripheral neuropathy. Further research is needed to test their safety and effectiveness before being applied in clinical practice.
