As measure against the rapid spreading of coronavirus disease 2019 (COVID-19) which now has reached global level, Indonesian government established Large-scale Social Distancing (LsSD). As consequence, learning method used in junior and senior high school is substituted from face-to-face learning in class to online distance learning, including for science and biology. This study was conducted to know software preference used by science and biology junior and senior high school teachers for online learning during LsSD measure. A total of 189 science and biology junior and senior high school teachers from various area had given their response via questionnaire. Data was analyzed using quantitative descriptive method. About 57% respondents had never manage online learning before COVID-19 pandemic while the remaining 43% had experience in managing one before, however almost all managed online learning. Non-paid software used the most (81%) among respondents to manage online science/biology learning. Software types used were social networking (64%) especially WhatsApp, learning management system (LMS) (51%) especially Google Classroom, teleconference applications (12%), and assessment software outside of LMSs (15%). Software chosen were mostly non-paid, easily accessed by all people, already familiar among Indonesian, and its interface were easily mastered.
A new coronavirus, SARS-CoV-2, is responsible for the current pandemic causing severe respiratory disease. It has been known that the receptor for SARS-CoV-2 entry into the host cell is the angiotensin-converting enzyme 2 (ACE2). This receptor is expressed in a wide array of organs, for example, the kidneys and gastrointestinal tract, but rarely present in the circulation. The soluble form of ACE2 proposed as a potential therapy for SARS-CoV-2 infection. This research aimed to explore angiotensin-converting enzyme 2 (ACE2) from marine biota as the source of ACE2, which is potential for the therapy of SARS-CoV-2 infection. This explorative study was conducted by retrieving the angiotensin-converting enzyme 2 (ACE2) from the database of protein (UniProt). The samples of the study were ACE2 of marine vertebrate, namely Delphinapterus leucas and ACE2 of marine invertebrate, namely Protunus trituberculatus. 3-D structures of ACE2 proteins unavailable in the protein database were modeled in Swiss Model. Molecular docking was conducted by using ClusPro.2.2. The data were analyzed descriptively. The molecular docking results revealed that the binding energy of spike glycoprotein of SARS-CoV-2 and human ACE2 was -988.5 kcal/mol. The binding energy of spike glycoprotein of SARS-CoV-2 and Delphinapterus leucas (Beluga whale) ACE2 was -946.4 kcal/mol. Meanwhile, the binding energy of spike glycoprotein of SARS-CoV-2 and Protunus trituberculatus (swimming crabs) ACE2 was -778.4 kcal/mol. The binding energy of spike glycoprotein of SARS-CoV-2 and Delphinapterus leucas (Beluga whale) ACE2 was closed to the binding energy of spike glycoprotein of SARS-CoV-2 and human ACE2. Hence, ACE2 of Delphinapterus leucas has the potential to be used as a therapeutic candidate from marine biota to suppress the SARS-CoV-2 transmission.
Indonesia reduces the spreading of COVID-19 infection by physical distancing. There is no argue that this policy affects all aspects, including education. Online learning has replaced the ordinary procedure of learning, whether we are ready or not. Organizing an online learning becomes an evitable challenge, especially for biology as a subject that has a lot of practicum. This research aimed to describe biology online learning in Indonesia during pandemic as well as describe the efforts of biology teachers to conduct an online learning. 109 biology teachers of senior high school from several regions of Indonesia were involved as respondents. Online questionnaires were conducted to collect teacher's responses using Google Forms then descriptive-quantitatively analyzed. The results indicated that biology teachers have a great intention to conduct online learning regardless of age and prior experience. Almost half of them (42%) never managed an online learning before the pande mic. However, almost all biology teachers (95%) managed their classes by online. Looking for free applications and study independently became the main alternative to improve their skill to manage an online learning, while some of them learned from friends. Google Classroom was the most favorite application they choose (56%) as it is served for free by Google; meanwhile, some of them (23%) using WhatsApp Group, the familiar social media. Biology teacher's willingness to learn should be appreciated. Starting from lack of experience, almost half of them (49%) stated that there was no problem in organizing online classes. There were only 24% of application mastery constraints left; meanwhile others were related to student's control, mastery of subject and longer preparation time. Various learning activities were successfully managed by online classes starting from presenting materials to evaluation. Some of biology teachers (30%) also managed practical work by online classes, whether using a virtual laboratory or simple practicum guidance to do at home. Teacher's enthusiasm responses dominated the results of the questionnaire filling for both teachers with prior experience or teachers without prior experience. It can be concluded that the efforts of biology teachers were able to realize online learning during the Covid-19 pandemic.
