Abstract

Availability of clean water is a basic need in Dili City, Timor Leste, but uneven distribution, inadequate infrastructure, and limited resources are the main challenges. This study aims to analyze the factors that influence clean water services. The research method included multiple linear regression analysis to identify influential factors. Data was obtained through surveys, interviews, official reports and literature review. The results showed that piping distance and number of family members positively influenced water quality and quantity, while household income tended to decrease water quality and quantity. Expenditure on clean water improves water quality and quantity. For water continuity, the number of people in the family had a strong positive effect, while other factors had a negative effect. The coefficient of determination for water quality is 5.3%, water quantity 20.9%, and water continuity 5.9%, indicating that many other factors influence water services in Dili City.

Abstract

HIV/AIDS, an extremely harmful sexually transmitted disease, has had a significant impact on worldwide health, establishing itself as one of the most lethal epidemics ever recorded. In this study, a mathematical model is used to analyze how HIV/AIDS spreads and grows, taking into account high incidence rates. The model uses a set of typical differential equations to group people into different categories based on their health status, including those who are vulnerable, those who have been vaccinated, those who are asymptomatic, those who are symptomatic, and those who have AIDS. The effectiveness of the solution indicates that the model is clearly outlined and has important implications for epidemiology. By utilizing the next-generation matrix method, we calculated the basic reproduction number. In order to evaluate the model's stability, a comprehensive examination was conducted on both the local and global stability of both the disease-free and endemic equilibrium points. This analysis provides a comprehensive understanding of the model’s behavior, shedding light on the conditions necessary for the disease to persist or die out. Numerical simulations focusing on these key parameters demonstrate that achieving a disease-free environment is attainable, albeit requiring targeted interventions to maintain stability. This study underscores the significance of understanding saturated incidence rates in modeling HIV/AIDS transmission dynamics. The results offer important information for policymakers and public health authorities, allowing them to create successful tactics for managing the transmission of HIV/AIDS.

Abstract

Organic carbon availability is crucial for effective soil capability, suitability, and fertility potentials, which makes it a serious consideration among all soil parameters in the evaluation of soil nutrient availability and general carbon sequestration. This research article explored an appraisal of soil organic carbon content availability across diverse vegetation covers in Delta State, Southern Nigeria, including lowland rainforests, secondary regrowth, and wet grasslands. The study aimed to establish whether significant differences exist in organic carbon availability across the landscapes to determine soil suitability for functional utilitarian purposes. The methodology adopted was strictly a field survey where soil samples were collected in situ across the three different landscapes at depths of 0-15 cm (not meters), which is the zone of nutrient uptake and activity. A total of 90 samples, with 30 collected from each landscape, were drawn based on systematic stratification. The one-way ANOVA revealed no significant difference in soil organic carbon content across the studied landscapes (p = 0.54, p > 0.05), leading to the acceptance of the null hypothesis. This indicates that the landscapes share similar soil fertility and nutrient availability, supporting their equal suitability for agricultural uses, particularly for arable crop production and precision farming in wet grasslands.

Abstract

The research was conducted in the Cirahab Water Spring area, the research was carried out with the aim of determining the level of diversity of gastropod species in the Cirahab Water Spring area, Padarincang Village, Padarincang District, Serang-Banten Regency. The research carried out used an explorative method on the diversity of gastropods in Cirahab. The results of this research were 127 types of gastropods, including Thiara Scabra, Hemiplecta humphreysiana, Lissachatina fulica, Amphidromus palaceus, Pomacea speciosa, Cyclophorus perdix perdix. The largest number of black snails with the Latin name Thiara Scabra is 30. From the results of calculating the diversity index, the result is 2.162391948, this number shows the level, namely at the "Medium" level according to the Shannon Wiener formula. Apart from that, water measurements were also carried out to obtain results including water temperature of 24oC, water depth of 1 meter, clarity of 30, water pH of 7 (normal) and water flow of 0.30.

Abstract

One of the chronic and serious complications of diabetes mellitus is diabetic foot. Staphylococcus aureus bacteria is the most common bacteria found in this type of wound. The purpose of this study is to determine the antibacterial activity of parem Karo, which is one of the traditional medicines of the ethnic culture of the Karo tribe which is rich in spices. The results showed inhibitory activity at higher concentrations with the largest average inhibition diameter at 75% concentration against Staphyloccocus aureus bacteria (8.23 ± 0.72 mm) followed by 50% concentration with an average inhibition diameter (7.52 ± 0.2 mm) and at 25% concentration showed no inhibition zone at all. The conclusion obtained from this study is that there is antibacterial activity of Karo hot parem extract at a concentration of 75% and 50% against the growth of Staphyloccocus aureus bacteria.
