Purpose: As coronavirus disease 2019 (COVID-19) continues to spread rapidly causing approximately 186 million confirmed cases around the world, the urgency to reach herd immunity through vaccination is increasing. However, vaccine safety is a top priority to limit the occurrence of adverse events. Henceforth, this study aims to recognize and perceive COVID-19 vaccine safety in Indonesia during the pandemic. Materials and Methods: This is a cross-sectional study and was conducted in Indonesia during the COVID-19 pandemic using an online survey of demographic information and a qualitative questionnaire. Responses were recorded and the association between demographic characteristics from survey questions was tested using chi-square with a risk estimate and 95% confidence interval. Results: A total of 311 participants from 33 out of 34 provinces in Indonesia participated in this study. Recorded responses showed multiple side effects of the COVID-19 vaccine both shortand long-term experienced by the participants. Significant associations were found between demographic factors and COVID-19 vaccine side effects such as female gender with shortterm puncture site (odds ratio [OR], 0.463; 95% confidence interval [CI], 0.263–0.816) and shortterm other reactions (OR, 0.463; 95% CI, 0.263–0.816), domicile outside Java island with longterm puncture site (OR, 4.219; 95% CI, 1.401–12.701) and immune reactions (OR, 3.375; 95% CI, 1.356–8.398), also between married marital status and long-term vagal reaction (OR, 4.655; 95% CI, 1.321–16.409). Conclusion: Gender, domicile and marital status factors were associated with COVID-19 vaccine side effects in Indonesian people.

Fusarium wilt of banana caused by Fusarium oxysporum f. sp. cubense is widespread in Indonesia. However, the distribution of tropical race 4 strains has not been well studied. Thirty nine isolates of F. oxysporum f. sp. cubense were collected from Java and 7 isolates were from Sumatera, Bangka, and Kalimantan. All isolates produced volatile odor when grown on steamed rice. These isolates were further tested for their vegetative compatibility with nitM testers of 20 reported vegetative compatibility groups representing strains that belong to race 1, 2, and 4. Three isolates formed heterokaryons with nitM testers belong to race 1, 11 isolates with race 4, and the rest did not form heterokaryons with all nitM testers used. F. oxysporum f. sp. cubense tropical race 4 specific primer pair was used to amplify a 1400 bp fragment of tropical race 4 DNA. Seven isolates (Bnt2, Mln1, Srg1, Bgl3, Bgl6, Lmp1, and Kjg1) produced the 1400 bp amplification product were therefore tropical race 4.

Geomechanical analysis using well log can be used to determine the fracable zone. Fracability is a parameter applied in the development of shale hydrocarbon to overcome the weaknesses in determining the fracable zone which was previously only based on high brittleness and considered a good hydraulic fracking candidate. The fracability model from the results of geomechanical analysis is used as the basis for hydraulic fracking planning for the development of Brownshale hydrocarbon in the Bengkalis Trough area, as a case study. Therefore, it has good development prospects. The geomechanical analysis of well BS-03, is the only well that penetrated the Brownshale formation. The geomechanical parameters investigation consists of Young’s modulus, Poisson’s ratio, unixial compressive strength, brittleness index, and the fracability index. Therefore, the fracability model is built by correlating the depth interval of the Brownshale formation and the geomechanical parameters, in order to determine the Brownshale formation interval as the basis for the location selection process and the hydraulic fracking interval. The results of geomechanical analysis show an interesting phenomenon in the fracability index, with negative and positive depth intervals at the top and bottom, respectively. The upper and lower depth intervals represent fracture barrier and fracable zone interval.

This work considers the elliptic restricted three-body problem under effects of radiation of the bigger primary, and an oblate spheroid for the smaller primary to mimic an exoplanetary system with a gas giant planet. Under the influences of both effects we look for the existence of the triangular equilibrium points and the influences of the radiation and oblateness on the locations and motion of the points. We set the system in a normalized rotating coordinate system and derive equations of motion for the third infinitesimal object. Our study shows that the effects modify the equilateral/isosceles triangle shape with respect to the primaries. The triangular points also have non-planar motion with period depending on the value of the planet oblateness.

Human breast milk contains numerous biomolecules. Human milk oligosaccharides (HMOs) are the third most abundant component of breast milk, after lactose and lipids. Amongst the synthetized HMOs, 2'-fucosyllactose (2'-FL) and lacto-N-neotetraose (LNnT) are widely studied and are considered safe for infant nutrition. Several studies have reported the health benefits of HMOs, which include modulation of the intestinal microbiota, anti-adhesive effect against pathogens, modulation of the intestinal epithelial cell response, and development of the immune system. The amount and diversity of HMOs are determined by the genetic background of the mothers (HMO secretors or non-secretors). The non-secretor mothers secrete lower HMOs than secretor mothers. The breastfed infants of secretor mothers gain more health benefit than those of non-secretor mothers. In conclusion, supplementation of infant formula with 2'-FL and LNnT is a promising innovation for infant nutrition.

Cu(In1-xAlx)Se2 thin films were deposited by one-step RF magnetron sputtering. The target was composed of mixed binary selenides of CuSe, InSe and pure aluminum powder. Smooth films surfaces with good adhesion to the substrate were grown successfully. All of the films show strong (112) and (204/220) single phase CuInSe2 peaks. Addition of Al to the target up to 6 wt-%, at the expense of indium, shifts the orientation peaks towards higher 2θ yielding films with an optical band gap between 1.05-1.7 eV. For the first time, this paper reports the application of a one step sputtering deposition process to grow Cu(In1-xAlx)Se2 thin films for solar cell absorber applications.

Highly conductive and transparent in the visible region tin-doped indium oxide(ITO) thin films were deposited on Corning glass by r.f sputtering. To achieve high transmittance and low resistivity, we examined various parameters such as r.f power and deposition time. The films crystallinity shifted from (222) to (400) and (440) orientation as deposition time and r.f power increased. Surface roughness RMS value increased proportionally with deposition time. The lowest resistivity was 5.36 × 10<SUP>-4</SUP> Ωㆍ㎝ at 750 ㎚ thickness, 200℃ substrate temperature and 125 w r.f power. All of the films showed over 85% transmittance in the visible wavelength range.
