Abstract

Sleep disorders increase with age, with prevalence approaching 50% in the elderly (65 years and above). In Indonesia, about 30% of the elderly experience sleep disorders. Several studies have shown that older people who have poor sleep patterns or who experience sleep disorders are at risk of dementia, mental illness, including anxiety and depression, hypertension, and cardiovascular disease. Sleep disorders can be treated with medication, but it can cause side effects such as drowsiness, poor concentration, and dementia. These side effects contribute to the risk of falls, accidents, and cognitive impairment. So to avoid these effects, a non-pharmacological approach can be taken, one of which is acupressure. Acupressure is the application of finger or thumb pressure on acupoints. This study aims to determine the effectiveness of acupressure on sleep quality in the elderly. The research used quantitative methods with a quasi-experimental research design. This design has a comparison group (control) and an intervention/treatment group, but before being given treatment (intervention), a pretest and posttest are carried out. The number of samples in this study amounted to 96 respondents, with the sampling technique used being purposive sampling. 96 respondents will be divided into control groups and intervention groups. The statistical analysis method used is the Wilcoxon test. The difference in the quality of elderly sleep before and after applying acupressure in the intervention group with an average (mean) of 0.479. As for the control group, -0.021. It can be seen that in the control group, there was an increase in value after applying acupressure. The p-value of the intervention group is 0.001 (p <α), where it can be concluded that there is a real (significant) difference in the average improvement in the quality of elderly sleep as seen from the value of each assessment before and after acupressure is applied.

Abstract

The coastal area of Negeri Latu, West Seram Regency, possesses a relatively high marine biodiversity and is a vital natural resource for the local economy, particularly in fisheries. However, increasing human activities around the coastal zone, such as the disposal of domestic waste, garbage, and industrial effluents, have exerted significant pressure on the quality of the marine environment. This study examines the utilization of aquatic biota as early pollution indicators in the coastal area of Negeri Latu, West Seram Regency. This research employs a descriptive quantitative approach. The coastline of Negeri Latu spans approximately 900 meters, with nine transects established perpendicular to the shoreline, each spaced 100 meters apart. Ten observation plots (1×1 m) were placed alternately along each transect at 10-meter intervals. Marine biota were observed, quantified, and identified to determine their species. The analysis results indicate that the pollution status in these waters falls under the Moderately Polluted category. This classification reflects a significant disturbance to water quality, although it has not yet reached severe pollution. The decline in water quality is attributed to various anthropogenic factors, particularly the local population’s high volume of waste disposal into the sea. The waste includes both organic and inorganic materials, contributing to marine environmental degradation through physical (e.g., water turbidity and discoloration), chemical (e.g., pH changes, increased levels of heavy metals and toxic compounds), and biological (e.g., reduced diversity and abundance of marine organisms) means.

Abstract

Dengue hemorrhagic fever (DHF) is an endemic disease found in nearly all provinces of Indonesia. The occurrence of DHF is closely associated with climatic factors on spatial, temporal, and spatio-temporal scales. The search for new methods to eliminate the sources of dengue virus transmission is both urgent and essential. Sargassum duplicatum, a species of brown seaweed native to Indonesia, has been shown to possess potential antioxidant properties. This alga contains bioactive compounds, including steroids, alkaloids, phenols, flavonoids, saponins, and tannins, which are suspected to be toxic to insects. This study aimed to evaluate the larvicidal activity and determine the LC₅₀ and LC₉₀ values of ethanol extract from Sargassum duplicatum against the larvae of Aedes aegypti mosquitoes. A completely randomized design (CRD) was employed, consisting of five treatment groups with three replications each. A total of 300 third-instar Aedes aegypti larvae were introduced into treatment containers containing predetermined concentrations of Sargassum duplicatum ethanol extract, with each container holding 20 larvae. Observational data were analyzed using ANOVA and probit analysis. Phytochemical screening of the ethanol extract from Sargassum duplicatum confirmed the presence of flavonoids, saponins, tannins, and alkaloids. The extract demonstrated increased larval mortality in Aedes aegypti with increasing concentrations. A concentration of 75 ppm exhibited larvicidal efficacy comparable to that of 1% Abate. The LC₅₀ value of the ethanol extract was calculated to be 9.098 ppm, while the LC₉₀ value was 20.485 ppm.
