Research on the optical properties of the ZnO thin film with the use of sol-gel method and spin coating method using 0.5 M concentrate solution of (Zn(CH3COO)2·2H2O) and 30 mL isopropyl alcohol as a solvent has been carried out. The production process of ZnO solution and the fabrication of the thin film with the optical properties test of the thin film are included in the scope of this research. UV-Vis Spectroscopy is used to obtain the transmittance and absorbance values on each wavelength and the band gap energy value using the Tauc Plot method. The transmittance value obtained is directly proportional with the temperature. The absorbance value obtained is inversely proportional with the temperature due to higher temperature causes the reaction rate to become faster and in turn causes the absorbance value to become lower. The band gap energy value obtained is on the range of 3.23 eV – 3.27 eV and it fit with the literature.
Leprosy remains as a health problem in Indonesia. This retrospective descriptive study analyzed the succesfulness of controlling and prevention of leprosy by Deparment of Health Aceh Tenggara Regency (DHATR), Indonesia period 2010 to 2019. The required data (n=125) were extracted from the DHATR databases using a self-designed questionnaire. The new cases, grade 2 disability rate, recovery rate with multi-drug therapy (MDT), isolation measures for leprosy patients, bacille calmette-guerin (BCG) vaccination for the patients’ families, and tertiary prevention were analyzed using a cohort analysis. Succesfulness of the program was analyzed by referring the study results with the National Guidelines for Eradicating Leprosy (NGEL). Of the 125 patients, 62.4% were male. The new cases found for period: 2010 to 2016, > 5/100,000 population; 2017 to 2019, < 5/100,000 population. The incidence of level 2 disability period 2010 to 2019 was less than 25 cases/10 years and recovery in paucibacillary leprosy (PBL) and multibacillary leprosy (MBL) from 2010 to 2019 reached 100%. The incidence of MBL was higher than that of PBL at the age range of 1 to 70 years.There was no patients isolated and vaccinated during that period. The controlling and prevention of leprosy in DHATR was in accordance with the NGEL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
