Abstract

BackgroundPulmonary fibrosis is often found in infectious diseases and chemical exposure in the work environment. Antifibrotic effects can befibropreventive and fibrolysis. Bleomycin can cause inflammation and pulmonary fibrosis. Catechin is proven can repair liverdamages due to alcohol induction. The aim of this study is to examine the effect of antifibrotic green tea catechin on reducing thearea of rat lung fibrotic.MethodsThis research was carried out in vivo experimentally in the Laboratory Animal Management Unit at Faculty of Veterinary MedicineIPB in 4 groups of rat experiments, consisting of 3 rats in the negative control group, 3 rats in the positive control group, 3 rats in thegroup of rats given bleomycin on the 8th day and 28thwith green tea extract every day from day 0 to 49 days (fibropreventive), 3groups of rats given bleomycin days 0 and 21 with green tea extract every day from day 15 to 49 (fibrolysis). Histopathologicalexamination was performe for all groups of rats.ResultsThis study showed that administration of green tea extract in fibropreventive groups and fibrolysis groups could reduce the fibrosisarea in rat lungs based on Aschroft's modified scale.ConclusionBased on the results of this study it was found that the anti-fibrotic activity of green tea extract was proven to be able to suppressthe development of pulmonary fibrosis both by fibropreventive and fibrolysis

Abstract

The purpose of this study is to examine the effect of the implementation of policies on reducing human activity regarding the covid-19 outbreak to the concentration of air pollution in March 2020 in the Jakarta area using a comparison of the time series of PM10 and PM2.5 hourly calculations calculated to be the daily average in March by applying the Pearson correlation equation and scatter diagram to obtain a pattern of relationships in the form of positive, negative or non-linear and the degree of weak, strong or perfect relationship between variables. The main contributions of this research are as follows: Evaluation of the significance of the decrease in the concentration value of the average PM10 and PM2.5 in March 2020 with a correlation to March variables in the previous year based on the acquisition of qualitative results in the form of a graph of the trend of decreasing PM10 and PM2.5 in March 2020 compared to March of the previous year and quantitative in the form of a negative correlation with the Pearson moment and scatter diagram showing a decrease in March 2020 compared to March of the previous year so that the policy of reducing human activity in a response to the Covid-19 pandemic has an impact on a better air quality condition in Jakarta.

Abstract

Hydroponics is a technique of growing plants without soil. Until now, many people do it manually for moisture, content, nutrition, and continuous flow of water. The application of ergonomics aims to make the user healthy, comfortable, safe, productive. The purpose of evaluating anthropometry-based ergonomics, and testing the hydroponic plant watering automation system tool. The method used is collecting anthropometric data on the dimensions of the user's body for ergonomics, then designing an automatic hydroponic watering tool to make it easier to design hardware and software. The results of the ergonomics evaluation study, hand span size 175.3 cm, upright body height 167.4 cm, shoulder to head 32.23 cm, shoulder to base of foot 66.77 cm, base of foot to knee 48.89 cm, base of foot to knee 48.98 cm, elbow to elbow 41.81 cm, elbow to hand 34.45 cm. While the results of testing the condition of the charcoal are at the humidity threshold of 49% - 60% then the pump will be on, and if the pot has been on the humidity threshold of 65% - 99% then the pump will be off.
