Abstract

Acute Respiratory Tract Infection (ARTI) remains a major infectious disease in Indonesia, significantly affected by inappropriate antibiotic utilization, potentially increasing bacterial resistance. This study aims to evaluate the rationality of antibiotic use among ARTI inpatients at Dr. Moewardi General Hospital, Surakarta. Utilizing a quantitative, retrospective descriptive design, all medical records of ARTI inpatients from 2023 to 2025 meeting the inclusion criteria were included as samples (total sampling). Data were collected using structured forms and processed using Microsoft Office and IBM SPSS Statistics 20; analysis was performed descriptively following Gyssens' criteria. The study found that although most patients received correct antibiotics with respect to indication (94.7%), drug type (94.7%), dose (100%), and timing (100%), only 34.2% received antibiotics for the appropriate duration. Rational antibiotic use by Gyssens' method was found in only 34.2% of cases. These findings highlight the high rate of duration errors and emphasize routine audits and educational interventions. It is concluded that, despite strengths in dosage and selection, duration of antibiotic use remains a challenge for rational therapy.

Abstract

Indonesia as a tropical country faces high UV exposure which causes premature skin aging and cancer risk, so it is necessary to have natural sunscreen from antioxidant-rich plants such as kepok banana flowers (Musa acuminata x M. balbisiana). This study aims to determine the Sun Protection Factor (SPF) value and protection category of water, ethyl acetate, and n-hexane fractions of kepok banana flowers. This type of research is descriptive experimental with ethanol maceration method, multilevel fractionation, phytochemical screening, TLC, and UV-Vis spectrophotometry (290-320 nm, Mansur formula).The results showed that the different types of solvents in each fraction influenced the resulting SPF value. The ethyl acetate fraction showed the highest protective activity compared to the other fractions. The SPF values ​​of the kepok banana flower water fraction with concentrations of 60 ppm, 80 ppm, 100 ppm, 120 ppm, and 140 ppm were 4.662; 7.757; 9.055; 11.944; 15.264, respectively, with moderate-ultra protection. The ethyl acetate fraction obtained SPF values ​​of 18.433; 18.968; 19.203; 19.672; 20.203 with ultra protection. The n-hexane fraction obtained SPF values ​​of 1.190; 1.762; 2.278; 3.575; 4.598 with the category of no-moderate protection.. Concludedthat kepok banana flowers have potential as a natural sunscreen agent, where the ethyl acetate and water fractions provide the most optimal sun protection effectiveness (SPF) compared to the n-hexane fraction.

Abstract

Acne vulgaris is a common dermatological problem in adolescents in Indonesia's tropical climate related to the activity of Propionibacterium acnes bacteria. Long-term use of antibiotics risks causing resistance, so natural antibacterial alternatives are needed. This study aims to evaluate the antibacterial activity of ethanol extract and fractions of n-Hexane, ethyl acetate, and pineapple peel water against Propionibacterium acnes ATCC 6919, and to determine the most active fraction and MIC and MBC values. This study is a quantitative experimental study. The study population was the bacterial culture of P. acnes ATCC 6919, with samples in the form of pineapple peel extract and fraction. The research instruments included disc diffusion and liquid and solid dilution methods, while data analysis used the Shapiro-Wilk, Levene, and Kruskal-Wallis tests. The results showed that the ethanol extract had moderate to strong antibacterial activity, the ethyl acetate fraction showed the highest activity compared to other fractions, while the n-hexane fraction showed no activity. MIC and MBC values ​​were obtained at a concentration of 20 percent. The conclusion of this study is that pineapple peel has the potential as a natural antibacterial source against P. acnes and the ethyl acetate fraction is the most active fraction.

Abstract

Dental caries remains a major oral health problem globally and in Indonesia, triggered by Streptococcus mutans biofilm. Chemical agents such as chlorhexidine have side effects, encouraging the use of natural alternatives from Moringa oleifera L. leaves. This study aims to evaluate the antibacterial activity of ethanol extracts and n-hexane, ethyl acetate, and water fractions against Streptococcus mutans ATCC 25175, identify the most active fraction, and determine the MIC and MBC. This quantitative study used diffusion and dilution methods. Bacteria: Streptococcus mutans ATCC 25175; samples: ethanol extract of Moringa oleifera L. leaves and n-Hexane, ethyl acetate, and water fractions. Data analysis used SPSS 25 One-Way ANOVA, Tukey (p<0.05). Results showed that the ethyl acetate fraction was the most active with 12.36 mm inhibition at 45%; MIC and MBC were 30% ANOVA significant (p=0.000). The ethyl acetate fraction has strong caries prevention potential, supporting herbal development.

Abstract

Indonesia has reached 20.4 million adults with the fifth highest number of diabetes in the world and is estimated to be 28.6 million by 2050. The use of acarbose has side effects such as digestive problems to potential for the liver and kidneys, so these problems can be overcome with herbal plant treatment, one of which is the active compound of neem leaves (Azadirachta indica). This study aims to analyze the interaction of 20 neem leaf compounds with α-amylase enzymes through the molecular docking approach, ADMET prediction, and modification of potential new compounds as antidiabetic candidates. This research was conducted in silico using PyRx-AutoDock Vina for docking, VegaZZ, PyMOL, and Discovery Studio for optimization and visualization, SwissADME for ADME prediction, and Toxtree for toxicity test. The docking method validation is expressed in RMSD values of <2 Å. The docking results showed that Kaempferol had a ΔGBinding of -7.9 kcal/mol, an RMSD value of 1.229 Å and had a similarity of amino acid residues to the native ligands ASP:197. Kaempferol has a good ADME profile, High (III) category toxicity and is mutagenic and carcinogen. The design of the new compound of Kaempferol i.e. 2-(4-hydroxycyclohexyl)-1-methoxybutane-1,4-diol has amino acid residue similarity to the native ligands ASP A:197, ΔGBinding -5.6, RMSD value 1,704 Å and has good ADME, Low (I) category toxicity. The active compound of neem leaves has the potential to be an inhibitor of the enzyme α-Amylase.
