Abstract

In this work, cellulose was isolated from sugar palm fibre (Arenga pinnata) and converted into sugar palm fibre nanocrystalline cellulose (NCCs) in the hamlet of Medan Sinembah, Indonesia. Alkalization and bleaching were the stages of the therapy process. The cellulose removed with 30 weight percent concentrated sulfuric acid was then used to isolate NCC. Using Fourier transform infrared spectroscopy (FT-IR), the chemical make-up of sugar palm fibre and NCCs was identified. On the basis of structural analysis, X-ray diffraction (XRD) was used. Scanning electron microscopy (SEM) was used for morphological examination, while transmission electron microscopy (TEM) was used to look into NCCs. The outcomes demonstrated that the extracted cellulose underwent bleaching and alkalization processes, respectively, to eliminate lignin and hemicellulose. The diameters of the sugar palm fibre and NCCs were determined 69.025 µm to 6.07±0.14 nm and, respectively

Abstract

February is climatologically the first peak of the dry season in the North Sumatra region, but floods can still occur. This study analyzes the characteristics of rainfall patterns that occur during extreme rainfall that occurred in the Medan area on February 27, 2022 which resulted in flooding in several areas in Medan with Pearson correlation. The data used are rainfall data, satellite data, radar and other atmospheric dynamics analysis data. Based on dynamic analysis on February 27, 2022, the growth of CB clouds began at 14.00 WIB reaching its peak at 17.00 WIB where the peak temperature of the cloud reached 82.4 ° C and cloud growth lasted until 21.00 WIB, where the rain lasted long enough to cause hydrometeorological disasters (floods) to occur. The Pearson correlation coefficient method (r) used to analyze the relationship between rainfall and DMI, ENSO, SST Anomalies and SOI conditions can be seen that the dominant influence is SST Anomalies and SOI, where in February conditions that affect rainfall are ENSO with a correlation value of 0.36272 and SST Anomalies with a correlation value of 0.37548.

Abstract

This research was conducted to synthesize MgFe2O4 using the coprecipitation method by varying the concentration of NaOH. In this study, MgCl26H2O, iron sand, 37% HCl and variations of NaOH (5 M and 10 M) were mixed at 90 ℃ for 60 minutes, then washed using distilled water and ethanol until pH = 7, and calcined at 750 ℃. The test results using X-Ray Diffraction (XRD) showed that the diffraction pattern of phase formation identified was MgFe2O4 with hkl values (220), (311), (400), (422), (511), and (440). The resulting crystal size decreased with the addition of NaOH concentration. The test results using a Vibrating Sample Magnetometer (VSM) show that the magnetization value decreases when the crystal size decreases.

Abstract

The survival rate in cases of cardiac arrest outside the hospital is still low, besides that the public's knowledge about CPR is still limited, and there is a critical time limit for performing CPR. Therefore, the role of lay people, including nursing students, in CPR is important. Improving the knowledge and skills of nursing students in CPR through effective learning methods, one of which is using offline and online methods. This study aims to see differences in learning methods between offline and online methods in increasing the knowledge and skills of Cardiac Pulmonary Resuscitation (CPR) in students of STIKes Hutama Abdi Husada Tulungagung. This research is a quasy experimental research with a posttest only control design approach. The research sample consisted of 56 students who were divided into two groups. The research instrument used questionnaires and observation sheets with statistical tests using Mann Whitney. The results showed that learning methods using both offline and online methods could significantly increase respondents' knowledge about CPR (p=0.002) but did not show a significant difference in respondents' skills in performing CPR (p=0.052). The two learning methods both offline and online have their respective effectiveness, where the online method is more effective in increasing students' knowledge and skills on RJP.
