Faktor Munculnya Gejala Stres pada Mahasiswa secara Global Akibat Pembelajaran Jarak Jauh di Masa Pandemi Covid-19

This study aims to determine the variable emergence of side effects of pressure on students globally due to distance traveled during the Coronavirus pandemic. The method used is literature (meta-analysis) by reviewing articles that discuss indications of stress (stress) in college students globally. The results showed that the emergence of symptoms of pressure on students was caused by distance and piling up of coursework, learning environment, noise, limited understanding of the material obtained, limited knowledge, piled up homework, not having the option to meet friends and family including schoolmates, forced internet networks, inefficient web standards, no proper class plans, unstable internet networks, relatively expensive data costs and fatigue experienced during distance learning. As a result, students experience stress during the COVID-19 pandemic. In conclusion, students globally experience stress due to several factors arising from distance learning during the COVID-19 pandemic.   Keywords: COVID-19, Symptoms of stress, Distance learnin

Pengaruh Perendaman 4 Jenis Daun Tanaman Terhadap Mortalitas Larva Nyamuk Culex Quinquefasciatus dan Implementasinya Pada Materi Protista Kelas X SMA

This study aims to determine the effect of soaking 4 types of plant leaves on the mortality of Culex quinquefasciatus mosquito larvae, and to determine the four types of plant leaves that most influence the mortality of Culex quinquefasciatus mosquito larvae, and to determine the four types of plant leaves that affect the mortality of Culex quinquefasciatus mosquito larvae. can be used as teaching materials in the learning process of Protist Biology. The type of research used is experimental research using a Randomized Block Design (RAK) with 4 treatments and 1 control. The sample is 20 Culex quinquefasciatus mosquito larvae. The data collection technique used is observation. Data analysis techniques used are mortality test, ANOVA test, and continued with the BNJ test. The results of this study showed that each treatment of the four leaf extracts affected the mortality of Culex quinquefasciatus mosquito larvae. Observation of the treatment of soursop leaf extract (Annona muricata L.) showed that at 24 hours there was 0.5% mortality, at 36 hours there was 0.95% mortality, and at 48 hours there was 1% death, so it can be concluded that the soursop leaf extract treatment (Annona muricata L.) greatly affected the mortality of Culex quinquefasciatus mosquito larvae which was marked by an increase in the percentage of larval mortality every hour. The results of this study are used as material for Biology learning activities for class X semester I SMA on basic competence protist material 4.6 presenting reports on the results of investigations about the various roles of protists in life. Keywords: Larvae mortality of culex quinquefasciatus mosquito, four types of plant leaves, implementation on protist material class x sm

Docking Molecular dari Kompleks Zn(II)Amina (Prolin)dithiokarbamat terhadap Reseptor Estrogen-α

Estrogen-α (ER-α) is a major target in cancer therapy. Targeting the ER-α target protein is known to slow the proliferation of breast cancer cells. The purpose of this study was to determine the interaction of the complex compound Zn(II)Prolinedithiocarbamate against the Estrogen-α Receptor. The Zn(II)Prolinedithiocarbamate complex was predicted canonical SMILE by Cheminfo online application (O=C(O)C1CCCN1C2S[Zn]S2) and modeled with online corina to obtain a three-dimensional structure. The structure of the complex compound Zn(II)Prolinedithiocarbamate interacted with Estrogen receptor alpha protein to test its potential anticancer activity. Molecular docking results show the interaction of the Zn(II)Prolinedithiocarbamate complex with the Estrogen- receptor on the amino acid residues ARG394, LEU387, GLU353, LEU346, LEU349, and PHE404. The Zn(II)Prolinedithiocarbamate complex interacts directly with ER-α in the estrogen region which causes the failure of the interaction between estrogen and the estrogen receptor, so it can be predicted that the Zn complex has activity as an ER-α inhibitor and has the potential to be developed in the treatment of breast cancer
