Abstract

Due to COVID-19, media is needed so that students can continue to carry out practical activities at home to improve their understanding of chemical concepts. This study aimed to develop and determine the quality of a simple practicum video on redox material. This research is development research (R&D) with a 4D model (Define, Design, Development, and Disseminate), but this research is only up to the development stage. This simple video practicum on redox material contains the redox process on nail corrosion, the redox process on betadine with vitamin C, and the redox process on Onions with potassium permanganates. The product is assessed by one material expert, one media expert, four reviewers, and ten class X students respond. The results of the product quality assessment by material experts, media experts, and reviewers (senior high school chemistry teachers) get a percentage of 97.14%, 90%, and 91.81%, with a very good category. Then, the results of student responses obtained a percentage of 95% with a very good category. Based on this assessment, it can be concluded that simple practicum videos on redox material can be used as an alternative source of practicum during the COVID-19 era.

Abstract

Fibroblasts that produce excess collagen and growth factors play a role in the pathogenesis of keloid formation. In general, keloids are treated with intralesional corticosteroids alone or with a combination of other modalities, but the recurrence rate is still relatively high, so alternative treatments such as stem cells are being investigated, one of which is Mesenchymal Stem Cells (MSC), which have proven to be useful in healing keloids. Therefore, this literature review aims to discuss the effects of stem cell therapy in the treatment of keloids. In this literature review, 36 journals were used that discussed stem cell therapy in the treatment of keloids taken from various journal sources, namely Google Scholar, Pubmed, Medline, Ebsco, Hindawi, and Cochrane which were published within the last 10 years. According to the source, MSC is divided into 2 types, namely Adipose Mesenchymal Stem Cells (AMSC) and Bone Marrow Mesenchymal Stem Cells (BMMSC). In several studies, AMSC is known to reduce the expression of TGF-β1, COL-1, and COL-2 proteins, and has been shown to inhibit the proliferation of fibroblasts in keloid patients. Whereas in the BMMSC study that was applied with Hydroxybutyl chitosan (HBC) and Arg-Gly-Asp (RGD) hydrogels for 7 days, it was shown to significantly reduce nodular collagen fibers (p<0.05). Keloids occur due to excessive production of collagen and are influenced by various factors such as age, gender, skin color, and genetics. Stem cell therapy, such as MSC, has been proven in various studies to be an alternative treatment for keloids

Abstract

The aim of this research is to reduce household organic waste through the use of organic waste as a natural detector of formaldehyde content in food snacks. The organic waste used in this study was red garlic skins, dragon fruit skins and purple sweet potato skins. This research is an experimental research. The stages of the research started with the extraction of anthocyanins from the three organic wastes, direct detection of formalin and detection of food ingredients. The formalin concentrations tested were 0.5%, 1%, 2%, 5% and 25%. Detection ability can be seen from the color change between control and formalin treatment. Garlic skin produces a red extract, dragon fruit skin produces an orange extract, and purple sweet potato skin produces a deep red extract. Test results on 20 samples of food snacks around the campus using the three organic waste extracts proved that all samples contained formaldehyde in varying concentrations. The highest 50% formalin content was found in yellow noodles and meatballs. The conclusion is that purple beetle skin, dragonfruit skin, and red garlic skin can be used as natural detectors for formalin in campus snacks.
