Abstract

This research was conducted to determine the effect of CaCO3 levels on the formation of superconducting phase BPSCCO - 2212 by calculating the level of purity of the phases formed and looking at the microstructure. The variation of CaCO3 was 0.95, 1.00, 1.05 and 1.10 mole using the wet mixing method. The samples were calcined at 800 ° C for 10 hours, and sintered at 820 ° C for 20 hours. Synthesized samples were characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The XRD’s chacterization results show that the level of purity of the formed phases increases with increasing Ca levels with maximum point at BPSCCO-2212/1.10 mole. The highest volume fraction was 79,06% in the BPSCCO-2212/1.10 sample. While the lowest volume fraction was 72.10% in the BPSCCO-2212/0.95 sample. Meanwhile, the highest degree of orientation was 20.59% at BPSCCO-2212/0.95. The lowest degree of orientation was 8.46% at BPSCCO-2212/1.10. SEM’s chacterization results show of all samples have been oriented altought not perfect yet and have relatively little space between slabs (voids).

This activity took place in Hajimena Village, Natar District, South Lampung with 33 participants. Betel leaves are often found in people's yards and have potential as an antiseptic but have not been used properly and the culture of washing hands properly and correctly according to WHO recommendations is still lacking. These problems encourage the community to manage the potential of betel leaf as one of the family medicinal plants whose potential can be utilized to prevent the spread of Covid-19 and provide education and technical guidance to make hand sanitizers from betel leaf extract combined with the World Health Organization (WHO) formula. by applying a simple technique so that residents can process it independently, the result is that the community has been able to make their own hand sanitizer, and can wash their hands properly and correctly, supported by an increase in ICT achievement before service activities was 37.67%. Then, after the service activities were held, there was an increase in ICT achievement to 82.32%. This shows that there is an increase in public knowledge about the manufacture of hand sanitizers based on betel leaf extract.  Keywords: Betle Leaf, Hand Sanitizer, Covid-19, World Health Organization

Abstract

In this study, the characterization of the carbosil asphalt composite was carried out with a composition variation of 1:9; 1.5:8.5; 2:8; 2.5:7.5; 3:7 and the ratio for pure carbosil without the addition of asphalt. Carbosil is obtained from rice husk waste by using the pyrolysis method. This research was conducted to determine the effect of temperature on the microstructure, structure and functional groups of carbosil asphalt composites. XRD analysis obtained that the phase formed from each composition variation was an amorphous phase. The DTA/TGA analysis shows that there is a change in energy due to the addition of heat, which is indicated by the presence of mass shrinkage in the sample. Compressive strength results indicate that the strength of the carbosil asphalt composite with different material compositions affects the resistance to cracking.

Abstract

Research has been carried out aimed for looking effect of mixing Ethylene Glycol (EG) and propylene glycol (PG) on optical characteristics of silver nano wire (AgNWs) which synthesized using the polyol method. Synthesis was carried out for ± 5 hours on temperature of 130 oC inside erlenmeyer flask. The material used are silver (Ag) which is obtained from AgNO3, mixed solution of EG/PG with a concentration ratio of 100:0%; 75:25%; 50:50%; 25:75%; and 0:100%, FeCl3.6H2O, and capping agent in the form of Polyvynil Phyrolidone (PVP). The optical characteristics of AgNWs were observed through UV-Vis, FTIR, and length distribution through optical microscopy. The results of UV-Vis analysis showed four absorption peak at a wavelength of around 340, 350, 360 and at a wavelength of 390 nm as well as a change in the absorbance value. While the optical microscope test results also show that the length of the AgNWs increased on sample EG/PG 75:25% and 50:50%. Based on these results, it can be concluded that the mixing of EG and PG can affect the optical characteristics of AgNWs.
