The purpose of this study was to determine the effect of variations in the use of catalysts on the performance of brake pads. The performance testing is compressive strength and puncture strength. The resin is formed from a mixture of Bisphenol A-epichlorohydrin and cycloaliphatic amine. Based on the results of the study, it was found that brake pads with samples B and C had better performance. The hardness values of samples A, B, and C are 307.4; 331.1; and 334.3 N, respectively. The ratio of resin and catalyst mixture affects the performance of the brake pad. The more catalysts added, the faster the hardening process. It is hoped that this research can be the basis for developing brake pads.

The purpose of this study was to provide education regarding the prevention of malnutrition in early childhood at Tugu Elementary School, Cihideung Village, Parongpong, Indonesia. The method used is a qualitative descriptive study, which describes the situation in the field with social activities by providing educational insight on the theme entitled prevention of malnutrition at an early age. This research was conducted on 18 3rd grade students of Tugu Elementary School, Cihideung Village, Parongpong, Indonesia. With an age range of 8-9 years. Respondents consisted of 8 boys and 10 girls. This research was conducted through 3 stages, namely (1) pre-test; (2) providing education through learning media; and (3) post-test. The results obtained from this study there is a change in children's habits in consuming nutritious foods that contain carbohydrates or protein. And it can also be seen from the results of the pre-test and post-test that there is an increase in each statement given. With this research, it is hoped children can sort and choose nutritious foods or not and also with this research, it is expected to reduce the problem of malnutrition.

The many uses of gold nanoparticles in the biomedical field, including as an antimicrobial agent, prompted us to analyze the development of gold nanoparticles as antimicrobial agents research through a bibliometric approach with computational mapping analysis. The publication data used are publications from the Google Scholar database using the Publish or Perish Reference Manager software. The article's title, abstract, and publication year are used as a reference in processing publication data to make it more relevant and specific to the related topic, and the data is visualized by VOSviewer software. Found 257 highly relevant publication articles on related issues indexed by Google Scholar during the last ten years (2013 to 2022). The results show that research on associated topics has developed well because the number of publications has not decreased from 2013-2021, and until August 2022, the number of publications reached an amount equivalent to the number of publications in 2015-2017. The bibliometric results show that the publication trend of gold nanoparticles as antimicrobial agents is directed at studies on antimicrobial effect, antimicrobial property, and antiviral activity. The results of this study are expected to be used as a first step for further research on related topics.
