Abstract

Staphylococcus aureus, a gram-positive bacterium, is the causative agent of diabetic foot. Traditional medicine using plants needs much further research, especially for wound healing in diabetes mellitus patients. This study is an experimental laboratory investigation on the efficacy of Gotu kola (Centella asiatica) leaf extract against wound-isolated Staphylococcus aureus. Gotu kola leaf extract (12.5%, 25%, 50%, 75%, and 100%), cefixime suspension (positive control), and sterile distilled water were tested. The results of the research showed the formation of an inhibitory zone from testing Gotu kola leaf extract against Staphylococcus aureus bacteria, where the average inhibitory zone was at concentrations of 12.5% (7.2 mm), 25% (11 mm), 50% (13.7 mm), 75% (14 .3 mm), and 100% (19.5 mm). The higher the concentration used, the larger the inhibition zone formed. Research shows that Gotu kola leaves' active substances inhibit energy formation, nucleic acid formation, cell membrane permeability, structure and function, and membrane protein lysis and damage.

Abstract

Students' low ability to write narrative essays is caused by several problems in the learning process. These problems include teachers not using appropriate learning models in implementing learning. Teachers also do not use appropriate learning media. Apart from that, learning is still teacher-centered which causes students to be less actively involved in learning. This research aims to improve students' ability to write narrative essays using the Problem-Based Learning (PBL) model assisted by a series of pictures. This research is Classroom Action Research (CAR) involving 18 elementary school students. The approach used in this research is a mixed method approach or a qualitative and quantitative approach. The research was carried out in 2 cycles with data collection techniques in the form of document analysis, observation, and tests. The results of the research showed an increase in: a) assessment of teaching modules in cycle I 82.14% (Good) to 92.85% (Very Good) in cycle II, b) observations on the teacher aspect of cycle I 75% (Good) to 85% (Good) in cycle II, while implementation in the student aspect of cycle I was 75% (Good) to 85% (Very Good) in cycle II, c) the assessment of students in cycle I obtained an average of 69.10 and cycle II with an average of 80.10. Based on the research results, it shows that there has been an increase in students' writing skills using the Problem-Based Learning (PBL) model assisted by a series of images.

Abstract

Diabetes mellitus can increase oxidative stress and damage cells. Noni fruit has antibacterial, antifungal, antitumor, analgesic, hypotensive, and anti-inflammatory benefits, can boost immunity, and has antioxidant content. Noni contains phenolic compounds (anthraquinones, acuities, asperulosides, and scopoletin), organic acids (capric and caprylic acids), and alkaloids (xeronine). The effect of noni ethanol extract can significantly reduce blood glucose (P<0.05) of the T2 group (177.00±137.78) and T3 (159.40±86.53) when compared to the C+ group (511.00±131.45). The T1 group (387.40±170.06) had no significant difference (P>0.05) when compared to the C+ group (511.00±131.45), but there was a decrease in the average yield at T1 (387.40±170.06). Serum malondialdehyde (MDA) examination showed a significant decrease (p<0.05) in T1 (1188.32±93.41), while in T2 (1385.35±38.65) and T3 (1460.32±42.51) was not significant (p<0.05). Examination of serum glutathione peroxidase (GPX) showed a significant decrease in T1 (119.97±37.45), there was a decrease in GPX levels, while in the T2 group (236.14±6.05) and T3 (185.24±43.07), there was no decrease. Noni ethanol extract can lower blood glucose levels, reduce Malondialdehyde levels, and prevent increased activity of the enzyme glutathione peroxidase. Flavonoid compounds in noni ethanol extract can avoid increased blood glucose and reduce free radicals formed due to hyperglycemia conditions.

Abstract

Health services have an important role in the implementation of health services in hospitals as a whole, especially nursing. Health services are considered good if the health services can create a feeling of satisfaction for each patient. Achieving a level of satisfaction with the services provided to patients, both the quality of health services and the health service system, means that patients will prefer quality health services that are quality, guaranteed, and affordable to patients, or in other words, consumers are one of the most important factors in achieving the level of satisfaction in a health service. This research aims to analyze the quality of health services on the satisfaction of outpatients at Kolonodale Hospital, North Morowali Regency. This research is a quantitative study that uses an analytical survey research method with a "cross-sectional study" design approach, sampling by accidental sampling with a sample size of 50 respondents taken from outpatients at the polyclinic. The instrument used was a test developed using a Likert scale, the data obtained was analyzed using descriptive and analytical statistical analysis, namely the chy square test with a significance level of 5 percent. The results of the research showed tangible values (p=0.000), reliability (p=0.000), responsiveness (p=0.000), assurance (p=0.000), and empathy (p=0.000) because the value ρ<α (0.05) so it can be said that there is a relationship between tangible, reliability, responsiveness, assurance and empathy on outpatient satisfaction in Kolonodale Regional Hospital, North Morowali Regency. Tangible and empathy variables have the strongest level of relationship with patient satisfaction. So it would be better for the hospital to provide a suggestion box, so that input from patients can be conveyed and can help improve the quality of the hospital in the future.
