Abstract

Diabetes Mellitus (DM) is a metabolic disease characterized by hyperglycemia resulting from impaired insulin secretion, insulin action, or both. According to the IDF data, in 2021, there were 537 million people with diabetes globally, with more than 70% of them undiagnosed. In Semarang City, in 2023, there were 41,468 reported cases of diabetes, with the majority in the age group of 46-65 years. Public knowledge about diabetes, including its symptoms, risk factors, prevention, and management, is crucial to combat this disease. This research employed a descriptive-analytic epidemiological method with a Rapid Survey design. Data was collected in November 2024 at the Pramita Laboratory in South Semarang. The study population consisted of participants from a health education program themed "All We Know About Diabetes Mellitus," with a sample size of 90 respondents selected through total sampling. Data analysis was conducted using descriptive statistics. The findings revealed significant gaps in public knowledge about diabetes, including its etiology, classification, risk factors, diagnostic criteria, treatment, and complications. These knowledge deficits pose critical barriers to early diagnosis and effective management of diabetes, contributing to increased morbidity, healthcare costs, and socioeconomic burden. Addressing these gaps through targeted educational programs is imperative to reduce diabetes-related complications and improve community health outcomes. The results underscore the urgency for comprehensive public health strategies to enhance diabetes awareness and support preventative measures, particularly in regions with high prevalence rates like Semarang City.

Abstract

Understanding the diversity, function, and ecological dynamics of bacterial communities depends on unique transitional environments, estuaries. Knowledge on bacterial taxa in the Musi River estuary, South Sumatra still eludes, however. This effort aims to identify bacterial species in estuary waters using metagenomic analysis based on 16S rRNA gene. Surface water samples from three study locations were analysed by DNA isolation, nanodrop spectrophotometer qualitative assessment, 16S rRNA gene amplification, electrophoresis, and Illumina NovaSeq sequencing. Results showed that Proteobacteria predominated at all sites, followed by Campilobacterota, Cyanobacteria, and Bacteroidota. At the class level, Gammaproteobacteria was most common, followed by Alphaproteobacteria and Campylobacteria. Dominant bacterial orders were Campylobacterales, Rhodobacterales, and Pseudomonadales while the most common families were Arcobacteraceae, Rhodobacteraceae, and Pseudomonadaceae. The most plentiful genera were Rheinheimera, Pseudomonas, and Pseudarcobacter. Variations in bacterial spread among stations suggest environmental factors including salinity, nutrient availability, and human activities influencing microbial community composition. Ternary plots, heat maps, and krona diagrams were employed to disclose distinct patterns of bacterial community dispersion in the estuary. This paper underscores the importance of metagenomic research in illuminating microbial diversity in estuarine environments and its impact on ecological dynamics and water quality.

Abstract

Littoral zone often face environmental pressure due to anthropogenic activities, which can impact the quality of their ecosystem. This study analyzes the concentrations of copper (Cu) and lead (Pb) in sediments and benthic (Anadara granosa and Cerithidea cingulata). Sampling procedures were implemented during September 2022 across the aquatic habitats of Sembilang National Park, in South Sumatra Province, using the purposive sampling method. Sediment grain size and substrate type were analyzed using Shepard’s triangle. Metal detection using a spectrophotometric method based on atomic absorption. The results showed that the sediment fraction mostly consisted of clay, ranging from 92.03% to 94%. Cu concentrations in the sediment ranged from 5.01±0.017 to 5.71±0 mg/kg, while Pb concentrations ranged from 10.5±0.195 to 11.51±0.395 mg/kg. In the benthic, Cu concentrations ranged from 0.0037±0.00005773 to 0.0147±0.00000346 mg/kg, and Pb concentrations ranged from 0.0001±0.000227 to 0.005±0 mg/kg. According to the statistical evaluation testing via independent sample t-test showed that heavy metals differed significantly (p <0.05) between sediment and benthic compartments. These results show that the environmental quality in Sembilang National Park is still comparatively well maintained and within current quality requirements, despite certain activities that have the potential to pollute the environment. To guarantee the long-term viability of this area, it is advised that environmental quality be frequently monitored as a mitigation action.
