Kanker prostat merupakan merupakan kanker yang paling umum diderita oleh pria selama 2016, kasus baru pada penderita kanker prostat sudah diperkirakan sebanyak 180.890 dan kasus kematian 26.120 kasus. Terapi yang sering digunakan pada penderita kanker prostat ini salah satunya adalah kemoterapi. Kemoterapi dapat menyebabkan senyawa antikanker tidak sensitif, karena terjadi resistensi sel kanker. Maka dari itu, diperlukan pula metode alternatif pengobatan tradisional atau herbal. Dalam terapi kanker, penggunan tanaman herbal dinilai memiliki efek samping yang lebih kecil dibandingkan dengan terapi menggunakan obat-obat kimia. Daun pepaya (Carica papaya L.) merupakan salah satu tumbuhan yang telah diteliti memiliki aktivitas sitotoksik MiaPaca-2 dan ASPC-1. Dalam penelitian ini, dilakukan uji sitotoksisitas ekstrak etanol dan fraksi-fraksi daun pepaya (Carica papaya L.) terhadap sel kanker DU 145 untuk mengetahui aktivitas antikanker dengan menggunakan metode MTT Assay. Hasil uji sitotoksisitas terhadap sel kanker prostat DU 145 menunjukan esktrak etanol, fraksi n-heksan, fraksi etil asetat, dan fraksi air dengan berbagai konsentrasi 31.25, 62.5, 125, 250, dan 500 µg/mL.Fraksi N-heksan memiliki nilai IC50 sebesar 2,80 µg/mL dengan kategori sangat aktif. Hasil aktivitas sitotoksik tersebut dibuktikan dari hasil penafisan fitokimia dari daun pepaya. Metabolit sekunder yang bersifat nonpolar seperti alkaloid pada penafisan fitokimia memperoleh hasil positif. Hal ini membuktikan bahwa alkaloid (carpaine) berkhasiat melawan kanker. Sedangkan pada fraksi air dengan nilai IC50 sebesar 398 µg/mL, fraksi etil asetat sebesar 134 µg/mL dan ekstrak etanol daun pepaya memiliki nilai IC50 sebesar 151 µg/mL bersifat cukup aktif terhadap sel DU 145.

In vitro testing showed that awar awar (Ficus septica Burm. L ) leaf had an anticancer activity. Ethanol extract from awar-awar leaves could selectively inhibit cancer cell growth with IC50 values, there were MCF7 breast cancer cells (48 µg/ml), HeLa cervical cancer cells (122.4 µg/mL), and WiDR cancer cells (75.9 µg/mL). However, the active compounds that play a role in inhibiting the three cancer cells are not yet found. Therefore, this research carried out to find out the active compound using in silico. 3D-pharmacophore modeling and Molecular docking were developed for finding out the potential compound that could be acted as an anti-cancer agent. Screening pharmacophore was performed using LigandScout® 4.4 software for searching the matching pharmacophore features against chemical structure databases. Docking was performed using Autodock Tools® and visualized using Discovery Studio Visualizer® software to see the ligand interaction with the active binding site at the receptor and continue with ADMET properties to evaluating the Pharmacodynamic activities of the Hit compounds. Among 17 types of compounds tested, 11 compounds showed anticancer activity and genistin was found promising and showed potential inhibitory characteristics as an anticancer compared to other active compounds of awar-awar leaves. This study suggests that these compound could be used as a lead compound for anticancer agents.

Kata Kunci : Covid-19, Mencuci Tangan, Penggunaan Masker ABSTRACT Knowledge of preventing the spread of Covid-19 virus transmission for early childhood is very important because it is often difficult for children to be asked to wear masks and most children are not aware of the importance of cleaning their hands first before and after carrying out their activities both inside and outside school. . The purpose of this community service activity is to provide knowledge to SPS PAUD Darussalam students in Tambakbaya Village in anticipating the prevention of the spread of Covid-19 transmission through the movement of using masks and washing hands properly and correctly. The extension method consists of the stages of preparation, implementation, and evaluation. Starting from the activity of preparing the location, the participants were SPS PAUD Darussalam students, Tambakbaya Village, Cisurupan District, Garut Regency, West Java Province. At the implementation stage, it is provided with several stages such as explanation, discussion, and practice. The details of the activity are an explanation of leaflets on how to use masks and wash hands properly and correctly and practice 7 steps of washing hands using soap properly and correctly. The evaluation phase of the activity is carried out by continuing to build communication and provide important information with the Darussalam SPS PAUD teacher and also the head of Tambakbaya Village. The results of community service that have been carried out show that there is an increase in student understanding regarding the prevention of Covid-19 transmission by providing education on the use of masks and washing hands properly and correctly. The measurement of students' understanding ability is not done quantitatively using questionnaires but only qualitatively from the discussion and question and answer process that takes place after the presentation of the material. Students' understanding can be seen directly by asking several students to explain and demonstrate again the explanation of the material that has been given. The conclusion from this counseling is that there is a change in old behavior into new behavior in preventing Covid-19 transmission during the pandemic. This is expected to be a new, entrenched behavior for students in preventing the transmission of Covid-19. This counseling has great benefits in raising awareness for early childhood so that it contributes to preventing the spread of the SARS-CoV-2 virus that causes Covid-19. Keywords: Covid-19, Washing Hands, Wearing Masks
