Abstract: Context: Investigations of phytochemical screening and antibacterial activity were carried out on traditional medicinal plants collected in the highlands of Gayo Lues, Aceh Province, at an elevation of 1,000 meters above sea level (m.a.s.l.). Aims: To evaluate the antibacterial activity of plants chosen based on the interview results with the traditional healers (n = 5) in Gayo Lues. Methods: Ethanolic maceration was performed on the 12 identified ethnomedicinal plants and qualitatively screened for the phytochemical contents. Antibacterial activities against Escherichia coli ATCC 25922 and Staphylococcus aureus were tested for each extract based on the disc diffusion method, and MIC was determined using cephazolin as a reference drug. Results: The phytochemical screening of twelve plant species showed secondary metabolites class steroids, terpenoids, flavonoids, phenols, alkaloids, and saponins. Evaluation of the antibacterial activity of the extract (10 mg/mL) yielded inhibition zone ranges of 9.8 ± 0.26 to 21.87 ± 0.47 mm for E. coli and 8.93 ± 0.9 to 23.97 ± 0.68 for S. aureus. The ethanolic extract of Garcinia macrophylla Mart stem barks showed the highest antibacterial activity, where at the lowest concentration (1.25 mg/mL), the inhibition zones were found to be 19.2 ± 0.61 and 20.72 ± 0.44 mm for E. coli and S. aureus, respectively. The MIC was found to be 1.25 mg/mL. Conclusions: This study concludes that the twelve plant species are worthy of further investigation for novel antibacterial agent exploration.

Abstract: Introduction: Indonesia has the highest risk and vulnerability to both natural and non-natural disasters in the world. Aceh Province located on the confluence of two earth fault plates has been discovered to be exposed to a higher risk leading to significant physical, emotional, and psychological problems. Therefore, there is a need for immediate disaster response efforts to reduce the impacts, and nurses are the largest care providers with adequate competencies to ensure effectiveness. Objective: The study aims to develop a study protocol to measure the effectiveness of the intervention program to improve nurses’ competencies in disaster response. Methods: A sequential exploratory mixed-method study design will be used. A qualitative phase is to explore nurses’ competencies in disaster response according to nurses, disaster survivors, hospitalized patients, members of the Ulama Consultative Assembly of Aceh, and hospital policymakers using FGDs and in-depth interviews. The result of this phase is to develop intervention and instruments. Data are analyzed using a content analysis. A quantitative phase is to examine the effectiveness of the initiated intervention programs on nurses’ competencies in disaster response with a randomized controlled trial study design. There will be three groups in this phase, namely Evidence-Based Intervention (EBI) group, Islamic-Based Intervention (IBI) group, and Control Group (CG). The nurses’ competencies related knowledge, skill, and attitude will be measured using valid and reliable instruments. Data will be analyzed using independent t-test, and a repeated measure one way ANOVA. Discussion: The findings are expected to be the basis for the development of appropriate tools and better intervention in nursing practice and education in relation to evidence and Islamic-based disaster curriculum as well as a guide for future research.

Abstract: Background: Tabletop Exercise (TTE) is a specific learning method through a simulation designed to test the competency and the ability of a group to respond to disasters. Using the map of disaster events is considered effective to prepare disaster drills rather than other methods. TTE method has been carried out annually to train the students, however no studies reported the effect of this method.Purpose: The study aimed to evaluate the effect of TTE on enhancing nursing students’ knowledge and attitude in a disaster drill. Methods: This study was conducted with one-group pre and post-test of a quasi-experimental design. The total s lings were 80 nursing students of the fourth year who undertook the disaster nursing course. The intervention of the study was started using the scenario of an earthquake disaster simulation using TTE media ided into four groups. The instruments consisted of two questionnaires: Students’ Knowledge on Tabletop Exercise (SKTE), and Students' Attitude on Tabletop Exercise (SATE) which were tested for their validity and reliability. The data were analyzed using a dependent paired t-test. Results: The study showed that TTE had a positive effect in enhancing the knowledge (p=0.001) and the attitude of nursing students in disaster drills (p=0.001) (df=79). Conclusion: TTE intervention was an effective direct learning method to improve students’ competencies in disaster response. TTE might be considered as a learning method in improving students' competencies in preparing disaster drills.
