The peel-off gel mask is a type of mask that is easy and practical to use. Besides that, it can also hydrate the skin well. Spinach contains chemicals that are good for skin health including vitamin A, vitamin E, vitamin C, and flavonoids. The purpose is to determine the feasibility of peel-off gel masks with snapper spinach leaf extract in terms of laboratory tests (vitamin A, vitamin C, flavonoids, homogeneity, pH, drying time), organoleptic tests (color, aroma, stickiness, and texture), and hedonic test (favourability level). This type of research is an experiment with quantitative analysis. The independent variable is snapper spinach leaves. The dependent variable is the content of vitamin A, vitamin C, flavonoids, homogeneity, pH, and drying time contained in the peel-off gel mask. Data analysis techniques are observation and documentation. The formulations used are X1 (1%), X2 (3%), and X3 (5%). The results showed that in the peel-off gel mask of spinach leaf extract, there was 9568,0000 ppm (9.57%) of vitamin A, 0.088% vitamin C, (+) flavonoids, the X1 and X2 formulations were homogeneous, while the X3 formulation not homogeneous, pH 4.86, and average drying time of 20 minutes. The best formulation in terms of organoleptic and hedonic tests is X2 (3%) quite colorful (55.56%), quite flavourful (66.67%), sticky (66.67%), smooth (100%), likes (66,67%). Thus, the peel-off gel mask with snapper spinach leaf extract is suitable as an aging skin treatment.

BIM (Building Information Modeling) is currently a concept that can include important information in planning. This study aims Kosmetika Global Helath Indonesia, Ejip Area, Cikarang. In this research, 3D modeling of steel structures was carried out based on shop drawing documents from the research location. Next, calculate the quantity take-off for the estimated cost of steel structure work using Autodesk Revit software. It can be concluded that using Auusingit software can optimize the 2D modeling process into the 3D form so that the quantity take-off calculations can be more detailed and accurate and reduce material waste. It also already supports BIM 5D to help calculate estimated costs. The results of calculating estimated costs using Autodesk Revit software are 3.45% smaller than conventional calculations. It is because conventional methods are calculated manually based on 2D images, which allow for differences due to lack of detail.

Dry facial skin can be caused by several factors including age, sun exposure, weather, genetics, skin structure, diet, environmental factors, and skin diseases. The purpose of this study was to determine the effect of using traditional Moringa leaf masks for dry facial skin care. This type of research is experimental research with quasi-experimental methods. The research sample consisted of 6 samples using the purposive sampling method. The type of data used is primary data. Data analysis used the normality test, homogeneity test, and hypothesis testing (ANOVA), followed by the Duncan test. Analysis of normality and homogeneity of the data is used to test prerequisite analysis before testing the hypothesis. The results showed that in the control group (X0) without the use of traditional moringa leaf masks, there was no change in the level of skin moisture and the level of smoothness of facial skin texture. In the experimental group X1 and X2 using a traditional leaf mask showed a significant change in the level of moisture and smoothness of facial skin texture. There are differences in the effect of treating dry faces on women aged 35-45 years using traditional masks from Moringa leaves in three different treatments for indicators of moisture and facial skin texture with a significance of 0.016 <0.050.

SARS-CoV-2 is a positive-stranded RNA virus, the seventh coronavirus known to infect humans. Given the infectious nature of SARS-CoV-2 and its wide-reaching effects, finding a valid treatment is a top global priority. Although several vaccines have been used, the uncertainty remains unpredictable. Considering this, early diagnosis of SARS-CoV-2 is a prerequisite for effective containment and timely treatment, allowing doctors to intervene to prevent further spread and disease worsening. This study aims to provide references regarding the advantages and disadvantages of currently developing Covid-19 detection. This research is a Systematic Literature Review (SLR). The database analyzed in this study is in the 2019-2022 timeframe obtained from Google Scholar sources using Harzing's Publish or Perish for Windows version 8 search engine. Based on an article review, the Covid-19 detection test kits are grouped into 3, namely: acid-based detection methods nucleic acid (RT-PCR, dPCR, mNGS, RT-LAMP, CRISPR), serology-based detection methods (ICG/GICA, CLIA, ELISA, LFIA), and diagnostic CT imaging. Each method developed has its advantages and disadvantages. RT-PCR has always been the gold standard for detection. Other diagnostic techniques are also useful. Their combined results can exclude false negatives and positives as much as possible.

The 6th highest diseases that occur in Indonesian society include dental caries and periodontitis caused by dental plaque which is a breeding ground for bacteria such as Streptococcus mutants and Phorphyromonas gingivalis. The purpose of this study was to determine the effectiveness of chitosan on levels of Interleukin-6 and Malondhyaldehyde (MDA), as an anti-inflammatory marker using the Elisa test. The research method was a true experimental randomized posttest only control group design, with 3 treatment groups namely control, 2% chitosan gel, and 100mg/200g/bb of chitosan orally in 15 Wistar rats with periodontitis induced by Phorphyromonas gingivalis bacteria. The results showed that the mean levels of Interleukin-6 and Mallondhyaldehyde were significantly different (p<0.05) between the control group, chitosan gel treatment, and oral chitosan administration Interleukin-6 levels were the highest in the chitosan gel (8.3091±1.25570), the control average (5.8523±0.51512), the lowest oral average (3.2563±1.45952). Similarly, Mallondhyaldehyde levels were highest in the gel group (2.8850±0.19353), control group (2.2284±0.00914), and oral group (1.2943±0.60280).). Based on these results, oral chitosan was the most effective in the treatment of periodontitis.

Along with the development of the tourism industry, local culture has become valuable as a product and activity to attract tourists. The development of the Arak Bali formulation as a gastronomic drink was carried out by using pineapple as an infusion ingredient to produce Pineapple Infused Arak Bali. This type of research is a true experimental with a Post-test Only Control Group Design. The sample in this study was Pineapple Infused Arak Bali with FU and FD formulas. The purpose of this research was to determine the phytochemical profile and the concentration of bioactive compounds of the sample of Pineapple Infused Arak Bali. The determining of the phytochemical profile was carried out by qualitative tests while the quantitative analysis of bioactive compounds such as tannins, total phenols, and flavonoids was carried out by using the Folin-Denis, Folin-Ciocalteu, and AlCl3 methods by visible spectrophotometry. The results showed that Pineapple Infused Arak Bali contains phytochemical compounds, such as alkaloids, tannins, flavonoids, phenols, and terpenoids. The quantitative analysis results showed that the Pineapple Infused Arak Bali had tannin, total phenol, and flavonoid level of 52.9545, 42.005, and 6.8995 mg/100g. The results showed that the use of pineapple in the formulation of Pineapple Infused Arak Bali was able to increase the types of phytochemical compounds and the bioactive compounds levels compared to the original formulation, Arak Bali.
