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

The research was conducted in the SMP Putra 1 Jakarta. The method used in this quantitative assosiatif approach. The population in this research is VII, VII, IX grade students of SMP Putra 1 Jakarta, with the total sample of 83 respondents. Data was taken by using proportionate stratified random sampling. The prerequisite test in this study lilifoers normality test and rgresion linearity test, the result of the test that normal and linear. Result of correlation coefficient test are obtained -0,616 > 0,217. Result of t-test with significant level 0,05 obtained -7,04 > 1,99, it is explained that the are a negative correlation and significant correlation between parental control in the intensity of social media use on academic procrastination.

Abstrak Penelitian ini bertujuan untuk memperoleh gambaran tentang pengaruh pengawasan orang tua dalam intensitas penggunaan media sosial terhadap prokrastinasi akademik. Penelitian ini dilaksanakan di SMP Putra 1 Jakarta. Jenis penelitian ini adalah kuantitatif asosiatif. Populasi pada penelitian ini adalah siswa/i SMP Putra 1 Jakarta kelas VII, VIII, dan IX, dengan jumlah sampel sebesar 83 responden. Teknik pengambilan data menggunakan proportionate stratified random sampling. Uji prasyarat pada penelitian ini menggunakan uji normalitas lilifoers dan uji linieritas regresi, diperoleh hasil bahwa data berdistribusi normal dan bersifat linear. Uji hipotesis data yang digunakan adalah korelasi koefisien product moment diperoleh -0,616 > 0,217. Hasil uji t dengan taraf signifikan 0,05 diperoleh 7,04 > 1,99, hal ini menjelaskan bahwa terdapat korelasi negatif dan hubungan yang signifikan antara pengawasan orang tua dalam intensitas penggunaan media sosial terhadap prokrastinasi akademik. Perhitungan uji signifikan regresi diperoleh 30,68 > 3,96, maka terdapat pengaruh yang signifikan antara pengawasan orang tua dalam intensitas penggunaan media sosial terhadap prokrastinasi akademik. Pengawasan orang tua dalam intensitas penggunaan media sosial memberikan sumbangan efektif terhadap prokrastinasi akademik sebesar 37,9%, sedangkan sisanya 62,1% ditentukan faktor lain yang tidak diteliti.
