Abstract

Klebsiella pneumoniae is a gram-negative rod-shaped bacterium that is a member of the Enterobacteriaceae group of bacteria and is pathogenic and can infect humans. Currently, many K. pneumoniae bacteria are resistant to antibiotics, giving rise to new problems in the health sector that must be addressed immediately by utilizing biodiversity in the form of medicinal plants such as coconut trees, which can produce coconut shells that can be made into charcoal. The results of the phytochemical analysis show that coconut shell charcoal contains many active compounds that have been used in the cosmetic and health industries. The purpose of this study was to obtain an optimal and effective coconut shell charcoal extract gel formula for inhibiting the growth of K. pneumoniae bacteria. This study included a true experimental post-only control group with different gel concentration groups, namely 3%, 6%, and 9%. The optimal formulation of coconut shell charcoal extract gel is a gel with a concentration of 9%, and the results of the one-way ANOVA statistical analysis show that the treatment of the inhibition test on K. pneumoniae bacteria from gels with different concentrations shows that there is a mean difference in the area of the inhibition zone with a significant value of 0.033 (p<0.05). The results of the LSD post-hoc test showed that several treatment groups had significant values (p <0.05). Based on the results of the study, it can be concluded that the optimal formulation of shell charcoal extract gel is a gel with a concentration of 9%, while the most effective gel for inhibiting the growth of K. pneumoniae bacteria is a gel with a concentration of 3%.

THE CORRELATION BETWEEN ENVIRONMENTAL HYGIENE STORAGE CONDITIONS AND THE CONTAMINATION OF Escherichia coli IN MEATBALLS SOLD AT PURWOKERTO MARKET Abstract Meatballs, locally known as "bakso", are products made from processed meat and other foodingredients. They can be categorized into two types: ready-to-eat meatballs and packaged meatballs. In severalmarkets, packaged meatballs are sold and stored in arbitrary storage places without considering the storagearea's hygiene or the surrounding environment's sanitation. This lack of care can affect the quality of themeatballs, leading to health issues. One of the main concerns is Escherichia coli contamination, whichcan be attributed to improperly cleaned storage spaces and poor environmental sanitation. Objective: Thisresearch aims to identify the relationship between environmental sanitation hygiene and storage conditionsconcerning the contamination of Escherichia coli in meatballs sold at the Purwokerto Market. Employing a cross-sectional approach, this descriptive observational research randomlysampled twelve packaged meatball samples. Findings: Out of the research, E. coli contamination was found in 4samples. Specifically, Sample A2 had 120 colonies, B2 had 110 colonies, D1 had 171 colonies, and F1 had 137 colonies. Metallic green colonies on the EMBA medium marked this. According to Spearman's Rankcorrelation test, there was no correlation between environmental sanitation hygiene and storage conditionsregarding Escherichia coli contamination in the meatballs at the Purwokerto Market. Contamination might haveoccurred during the meatball production due to inadequate sanitation and hygiene practices. Keywords: Meatballs, Escherichia coli, Environmental Sanitation Hygiene, Hygeine Storage Conditions

Abstract

Diabetes mellitus (DM) is a chronic disease characterised by elevated blood glucose levels ≥ 200 mg/dl due to metabolic disorders. Insulin resistance triggers a blood glucose imbalance, resulting in no energy supply needed by the body's cells. The condition of DM is destructive to the body and, therefore, needs to be measured with stable parameters for the long term. HbA1c is a standard clinical examination used as a determinant of glycaemic status in DM disease. C-reactive protein (CRP) level is an effective parameter in determining the index of damage or inflammation that occurs in the body due to DM. This study aims to determine the relationship between HbA1c levels and CRP levels in patients with diabetes mellitus at Dr. Sardjito Hospital. Twenty patients with type 2 diabetes mellitus were included in this study using the purposive sampling technique. HbA1c data and CRP levels were analysed with the Spearman correlation test. The Pearson correlation test results showed a p-value = 0.001 and an r-value = 0.705. There is a relationship between HbA1c levels and CRP levels in DM patients at RSUD Dr. Soedirman Kebumen.
