Abstract

In December 2019, cases of mysterious pneumonia were first reported in Wuhan, Initially, the diseasewas temporarily named as 2019 novel coronavirus (2019-nCoV), then WHO announced a new name onFebruary 11, 2020, namely Coronavirus Disease (COVID-19) which is caused by a virus Severe AcuteRespiratory Syndrome Coronavirus-2 (SARS-CoV-2). This virus can be transmitted from person toperson and has spread widely in China and more than 190 other countries and territories. Meanwhile inIndonesia, up to September 2020, 203 thousand cases of COVID-19 were found and 8336 deaths. Batsact as important disease reservoirs for various etiologic agents of disease that can be transmitted betweenspecies, infecting humans and mammals, both domestic and wild. The purpose of this study was to analyzeSARS-CoV-2 immunoinformatics in bats in Karst Malang Indonesia as the basis for making SARS-CoV-2vaccines. This research method is SARS-CoV-2 amino acid bats in Karst Malang, Indonesia analyzed byimmunoinformatics. From the research results, it was found that SARS-CoV-2 protein from Malang Karstbats were antigen, non-allergen and non-toxin, so that they could be used as vaccine candidates, diagnostickits and immunotherapy.

Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan tanaman genjer dalam menurunkan kadar logam Pb pada air limbah. Penelitian ini dilaksanakan secara ekperimental menggunakan Rancangan Acak Lengkap (RAK) dengan menggunakan dua faktor variasi, yaitu jumlah tanaman (5, 10, dan 15 tanaman) dan waktu paparan (3, 5, dan 7 hari). Jenis reaktor fitoremediasi yang digunakan pada penelitian ini yaitu reaktor batch. Hasil penelitian menunjukan tanaman genjer mampu menurunkan logam Pb. Penurunan logam Pb yang paling efisien terjadi pada variasi 5 tanaman dengan lama paparan 7 hari yakni sebesar 0,06 ppm (99,6%). Namun, hasil penurunan tersebut belum memenuhi baku mutu air kelas 1 Peraturan Pemerintah Nomor 22 Tahun 2021 yaitu sebesar 0,03 ppm. Berdasarkan analisis statistik Kruskal-Wallis yang dilakukan, didapatkan P-value>0,05, atau tidak ada perbedaan nyata pada penggunaan variasi jumlah tanaman dan waktu paparan dalam menurunkan logam Pb.  Kata Kunci: Air Limbah, Fitoremediasi, Logam Berat Timbal, Tanaman Genjer.This study aims to determine the capability of yellow velvetleaf to reduce the Pb levels in wastewater. The research is accomplished by doing an experiment that uses a Completely Randomized Design (CRD)with two variation factor, the number of plants (5, 10, and 15 plants) and exposure time (3, 5, and 7 days). The type of phytoremediation reactor used in this study is a batch reactor. The result showed that yellow velvetleaf were able to reduce Pb. The most efficient reduction of Pb levels occurs in the variation of 5 plants with exposure time for 7 days which is equal to 0,06 ppm (99,6%). However, the results of this reduction have not met the class 1 water quality standard of Peraturan Pemerintah Nomer 22 Tahun 2021, which is 0.03 ppm. Based on the Kruskal-Wallis statistical analysis, it was found that the P value> 0.05, or there was no significant difference in the use of variations in the number of plants and exposure time in reducing Pb. Keywords: Lead Heavy Metal, Phytoremediation, Wastewater, Yellow Velvetleaf.
