Abstract

Soil-transmitted helminth (STH) infection remains a public health concern in rural tropical settings, where limited sanitation and high environmental exposure elevate risk. In Mataredi Village, most residents are subsistence farmers with constrained access to improved sanitation. Objective to estimate the prevalence of STH infection and assess its association with household latrine ownership in Mataredi Village, Katikutana District, Central Sumba. Methods: An analytical cross-sectional study was conducted in June–July 2024. A total of 144 residents aged >5 years who met inclusion criteria were enrolled using consecutive sampling. Fresh stool samples were examined by direct smear with 2% Lugol’s iodine. The association between latrine ownership (yes/no) and STH infection status (positive/negative) was evaluated using the Chi-square test; results are presented as p-value and odds ratio (OR) with 95% confidence interval (CI). Overall prevalence of STH infection was 19.4% (28/144). The species profile was dominated by Trichuris trichiura, with both single and mixed infections detected. Based on the Chi-square test, there was no statistically significant association between latrine ownership and STH infection (p = 0.943; OR 0.88; 95% CI 0.38–2.06). A mass deworming campaign conducted in May 2024 may have reduced detectable worm burden and attenuated observed associations.  The prevalence of STH infection in Mataredi Village was 19.4%, with Trichuris trichiura predominance. No significant association was found between household latrine ownership and infection status.

Abstract

Skin problems caused by Staphylococcus aureus infection remain a challenge in healthcare and personal hygiene due to their ability to trigger inflammatory responses through the activation of pro-inflammatory cytokines. The extensive use of synthetic antibacterial agents such as triclosan in body wash products has contributed to bacterial resistance, highlighting the need for safer natural alternatives. Nyamplung seed oil contains bioactive compounds, including calophyllolide, inophyllum B, flavonoids, and triterpenoids, which exhibit antibacterial activity against Staphylococcus aureus. Aloe vera also contains aloin, emodin, saponins, and polysaccharides with antimicrobial and anti-inflammatory properties. This study aimed to evaluate the potential of nyamplung seed oil and aloe vera extracts as active ingredients in body wash formulations to inhibit Staphylococcus aureus growth and alleviate skin inflammation. A laboratory experimental design was employed, in which nyamplung seed oil was extracted using the Soxhlet method, while aloe vera was processed by blending and concentrated through heating. The formulated body wash showed a pH of 9.45, homogeneous liquid consistency, yellow color, and a characteristic aroma of nyamplung oil. Antibacterial testing revealed an inhibition zone diameter of 28 mm against Staphylococcus aureus, indicating strong antibacterial potential.

Abstract

Mangrove ecosystems are unique habitats with extreme environmental conditions that select for adaptive endophytic microorganisms, making them a potential source of plant growth-promoting bacteria (PGPB). Exploring the potential of endophytes as biofertilizers to reduce dependence on chemical fertilizers is crucial in the context of sustainable agriculture. This study aims to characterize the potential of mangrove root endophytic bacteria from the coast of Lombok as biofertilizer agents through the evaluation of Indole-3-Acetic Acid (IAA) hormone production and phosphate solubilization ability. Endophytic bacteria were isolated from roots, evaluated for IAA production using the Salkowski method, while phosphate solubilization ability was evaluated qualitatively on Pikovskaya agar and quantitatively in liquid culture using molybdenum blue spectrophotometry. Potential isolates were characterized morphologically to determine their bacterial genus. The results showed that all isolates produced IAA, with AV1 (51.52 ppm) and AV4 (42.86 ppm) categorized as high producers. Phosphate solubilization ability varied significantly, with AV1 showing the strongest activity (index 4.41), followed by M1 (1.93), while some isolates showed low to no activity. Quantitative tests showed a peak in dissolved phosphate on day 4, with M2 (18.20 ppm) and M1 (16.31 ppm) being the most efficient phosphate solubilizers. Phenotypic characterization identified all promising isolates (AV1, AV4, M1) as Gram-positive, rod-shaped bacteria belonging to the genus Bacillus sp. based on Bergey’s Manual of Systematic Bacteriology. Overall, AV1, AV4, and M1 were identified as the most promising candidates for further development as biofertilizers.

Abstract

Eco-enzyme is a filtrate resulting from the fermentation of sugar, organic materials, and water, which is produced not only to reduce organic waste but also as a functional product. This study aims to examine the effects of sugar type and the eco-enzyme's fermentation duration on three key parameters: bacterial optical density, hydrogen peroxide concentration, and inhibition zone against Staphylococcus aureus and Escherichia coli. The bacterial optical density was determined from absorbance measured at 600 nm using a UV-Vis spectrophotometer, the hydrogen peroxide concentration was determined by permanganometric titration, and the inhibition zone of the eco-enzyme against Staphylococcus aureus and Escherichia coli was determined using the disc diffusion method. The results showed that the eco-enzyme fermented with molasses for one month had the highest bacterial optical density. Meanwhile, the highest hydrogen peroxide concentration was found in the eco-enzyme fermented with molasses for three months. In addition, the eco-enzyme fermented with molasses for three months exhibited the highest antibacterial activity against Staphylococcus aureus and Escherichia coli, with inhibition zones of 6.59 mm and 6.37 mm, respectively. Eco-enzymes fermented with granulated sugar, palm sugar, and molasses all showed antibacterial activity against Staphylococcus aureus and Escherichia coli. However, the highest antibacterial activity against both bacteria was observed in the eco-enzyme fermented with molasses for three months.

Abstract

Indonesia is a mega-biodiversity country with a wealth of medicinal plants and strong ethnobotanical knowledge among indigenous communities. However, modernization and the declining interest of the younger generation have caused traditional knowledge and the availability of medicinal plants to be increasingly threatened, including in Kedayon Village, Kemanisan Subdistrict, Curug District, Serang City. This study aims to: identify the types of medicinal plants used by the Kedayon Village community, describe how they are utilized in traditional medicine, and analyze forms of conservation efforts that can be implemented by the community in a sustainable manner. The method used is descriptive qualitative through field observation, documentation, and interviews. The results of the study identified 16 types of medicinal plants utilized from various plant parts such as leaves, roots, rhizomes, and seeds, with simple processing techniques such as boiling, squeezing, or steeping. These findings indicate that the community still relies on natural resources for traditional health needs. Recommended conservation efforts include community-based in-situ cultivation through home gardens and yards, accompanied by education and routine maintenance. These efforts are important to maintain the scarcity of medicinal plants while preserving local knowledge for future generations.

Abstract

Long-term kidney disease is a worldwide health issue that is becoming more common, leading to numerous individuals needing ongoing hemodialysis treatment. Understanding the illness and the management of hemodialysis is vital for successful treatment and improving life quality. However, the length of time a patient undergoes hemodialysis does not always match their level of understanding about the condition. The aim of this study was to determine the relationship between hemodialysis duration and knowledge levels about chronic kidney disease among hemodialysis patients in Kupang City. The research method used was analytical with a cross-sectional design. Sampling was conducted using purposive sampling according to specific inclusion criteria. Knowledge levels were assessed using the Chronic Kidney Disease Knowledge Questionnaire, while the duration of hemodialysis was gathered from medical records. The data analysis involved univariate and bivariate analysis, utilizing the Chi-square test (p < 0.05). A large portion of the participants were between the ages of 52 to 66 years (41.1%), had completed high school (35.6%), and were either unemployed or retired (36.2%). Regarding the length of hemodialysis, the majority of participants fell into the category of more than 24 months (43.6%). Knowledge levels ranged from good to poor. Bivariate analysis indicated no significant connection between the duration of hemodialysis and the understanding of chronic kidney disease (p-value = 0.500). There is no association between the length of hemodialysis and the understanding of chronic kidney disease among patients receiving hemodialysis in Kupang City.

Abstract

Low Back Pain (LBP) is a musculoskeletal problem that is often experienced by the elderly and can reduce the quality of life. Knowledge of LBP risk factors plays an important role in efforts to prevent and treat it. This study aims to determine the relationship between the level of elderly knowledge about LBP risk factors and the incidence of LBP at the Mandalika Elderly Social Service Center, West Nusa Tenggara in 2025. This quantitative study used a cross-sectional design on 41 elderly people selected through total sampling. Data was collected using a questionnaire that had been tested for validity and reliability, then analyzed univariately and bivariously with Chi-square test. The results showed that most of the respondents had sufficient knowledge (46.3%), followed by low (34.1%) and good (19.5%) knowledge. The incidence of LBP was found in 26 respondents (63.4%), while 15 respondents (36.6%) did not experience LBP. The Chi-square test showed a significant relationship between the level of knowledge of the elderly and the incidence of LBP (p-value = 0.002). It was concluded that low knowledge was related to the high incidence of LBP. Continuous health education is needed to increase the understanding of the elderly in preventing LBP.
