Abstract

The formation of ZnO/Ag morphology in the form of ganglia structures that are overgrown with grains in previous studies has been shown to degrade the presence of E. coli bacteria. In this research, the variations of annealing temperature were studied, namely 250 ℃, 300 ℃, 350 ℃, and 400 ep when the 4% ZnO/Ag deposition had an effect on crystallinity and morphology. The crystallinity of ZnO/Ag was obtained by using the X-Ray Diffraction (XRD) test and the surface morphology of the ZnO/Ag layer using the Scanning Electron Microscope (SEM) test. The results of the research with the XRD test showed that the crystal structure of ZnO/Ag 4% was hexagonal wurtzite at annealing temperature of 250 ℃ and 300 ℃, while the amorphous structure was obtained in ZnO/Ag with annealing temperature of 350 ℃ and 400 ℃. The largest average crystallite size was owned by ZnO/Ag at annealing temperature of 300 ℃ which was 83.408 µm. The morphology obtained from a thin layer of ZnO/Ag 4% with annealing temperature of 250 ℃ and 300 ℃ is in the form of grains composed of ganglia structures. The ZnO/Ag layer with annealing temperature of 300 ℃ had the largest roughness level of 0.422 µm and the largest surface area of 197.233 µm. Meanwhile, the morphology of ZnO / Ag at annealing temperature of 350 ℃ and 400 ℃ did not form a ganglia structure so that the roughness level was low and the surface area was small. The larger the crystallite size, the higher the roughness level, and the larger the resulting surface area. ©2018 JNSMR UIN Walisongo. All rights reserved.

Abstract

This study aims to determine the feasibility and the effectiveness of using a video tracker application for practicum of physics 1 on momentum conservation. This is included in research and development type. Stages carried out in this study include: 1) define, is done by giving questionnaires and interviews, 2) design, includes media selection, format selection and produce the initial product design, 3) development, includes product development and material expert validation assessment, media experts and linguists and limited field testing. The validation test results obtained that the media is feasible to use with a percentage of 88% based on material experts with very good categories, 85% based on media experts with very good categories, and 78% based on linguists with good categories. The effectiveness of media is shown by high average value of the experimental class of 84,06 compared to the control class of 70,97. Student responses to the use of products are categorized very well with a percentage of 89%.

Abstract

Double layer (DL) ZnO/ZnO:Ag has been synthesized with variations in molarity of 0.1, 0.3, 0.5,  and 0.7 M and its application as a degrading agent for methanil yellow dye. This study aims to determine the effect of the molarity of the DL ZnO/ZnO:Ag on crystallinity and photocatalytic activity for methanil yellow degradation. DL ZnO/ZnO:Ag was synthesized using sol-gel technique and deposited with spray coating technique. The results of DL ZnO/ZnO:Ag were characterized by XRD to determine the crystallinity and particle size. The photocatalytic activity was carried out by immersing the DL ZnO/ZnO:Ag layer in 10 ppm methanil yellow solution and irradiating it with UV light for 4 hours and then tested using UV-Vis spectroscopy to get the percentage of methanil yellow degradation. The results showed that the crystallinity of the DL ZnO/ZnO:Ag for all molarity variations had a hexagonal wurtzite structure. Grains size increase as molarity increases from 0.1 to 0.5 M. However, if the concentration continues to be increased to 0.7M, the grain size decreases. Photocatalytic activity is increasing every hour, as indicated by the increasing percentage of degradation. Precursor in 0.5 M has the maximum percentage of degradation is 25.32%.

Abstract

High blood sugar, cholesterol and uric acid are non-communicable diseases and are one of the causes of death in the world. Generally, this disease is very susceptible to be suffered by the elderly. One of the tests to monitor blood sugar, cholesterol, and uric acid levels is with an invasive disposable test kit. This method is inefficient because it causes the risk of infection, increases medical waste and is quite expensive. Real work students from Walisongo State Islamic University Semarang group 53 held a free examination in Krandon Village as an effort to carry out community service through appropriate technology in the health sector. Examination tools are made by lecturers and students using non-invasive methods (without injuring the body). Based on the results of student interviews with the community and health workers, this work program received a good response because the examination did not cause pain and helped reduce medical waste in the environment.
