USING SUPPORT VECTOR MACHINE TO IDENTIFY LAND COVER CHANGE DURING COVID-19 PANDEMIC IN KOMODO NATIONAL PARK, INDONESIA

The Covid-19 pandemic affects many areas of life, including the tourism sector. Furthermore, it significantly reduced the number of people visiting tourist destinations, and the reduction has helped to improve the environment in the National Park. Therefore, this study aims to present a satellite image classification method using Support Vector Machine to identify changes in the vegetation area of Komodo National Park. The satellite image used was created with Google Earth Pro with a resolution of 1920 x 1280 pixels using data collected in 2019 and 2020 before and during the pandemic. This study focuses on six tourist destinations in Komodo National Park: Loh Liang, Loh Buaya, Padar Island, Kanawa Island, Pink Beach, and Loh Sebita. The image was pre-processed using radiometric calibration, atmospheric correction, and contrast enhancement. The results of the pre-processing showed that segmentation will be performed to distinguish the area between one class and another. Furthermore, the image will be classified into five classes using the Support Vector Machine, including Soil, Vegetation, Built-Up Area, Deep Water, and Shallow Water. The measurement of the area of vegetation from 2019 and 2020 using Otsu’s thresholding showed environmental changes. Meanwhile, environmental improvements occurred in seven areas in the vegetation area category, with a 31.86% rise from 2019 to 2020. The increase in the area of green areas in the Komodo National Park all because tourist restriction and there is no climate fluctuations during the time of study. © 2022, Russian Geographical Society.

A framework for mapping and monitoring human-ocean interactions in near real-time during COVID-19 and beyond.

The human response to the COVID-19 pandemic set in motion an unprecedented shift in human activity with unknown long-term effects. The impacts in marine systems are expected to be highly dynamic at local and global scales. However, in comparison to terrestrial ecosystems, we are not well-prepared to document these changes in marine and coastal environments. The problems are two-fold: 1) manual and siloed data collection and processing, and 2) reliance on marine professionals for observation and analysis. These problems are relevant beyond the pandemic and are a barrier to understanding rapidly evolving blue economies, the impacts of climate change, and the many other changes our modern-day oceans are undergoing. The "Our Ocean in COVID-19″ project, which aims to track human-ocean interactions throughout the pandemic, uses the new eOceans platform (eOceans.app) to overcome these barriers. Working at local scales, a global network of ocean scientists and citizen scientists are collaborating to monitor the ocean in near real-time. The purpose of this paper is to bring this project to the attention of the marine conservation community, researchers, and the public wanting to track changes in their area. As our team continues to grow, this project will provide important baselines and temporal patterns for ocean conservation, policy, and innovation as society transitions towards a new normal. It may also provide a proof-of-concept for real-time, collaborative ocean monitoring that breaks down silos between academia, government, and at-sea stakeholders to create a stronger and more democratic blue economy with communities more resilient to ocean and global change.

Online Learning During the Covid-19 Pandemic Period: Studies on the Social Presence and Affective and Cognitive Engagement of Students

The fact that an educational institution is closed temporarily as one of the government's efforts and participation of education to withstand the pace of the spread of the Covid-19 pandemic. In line with that learning is diverted from the face-to-face system to online learning, in reality online learning the social presence of learners not as expected, on the other hand, learners who are usually active on offline learning both from affective and cognitive aspects are invisible to online learning. The research findings are learners who have an active social presence showing high affective and cognitive involvement in the study online, while students whose sociability passive involvement indicates that they do not engage both affective and cognitive studies during their studies. Researchers have concluded that students who are social and active in affective and cognitive involvement in offline learning do not guarantee the same conditions found online learning.

Anesthetic management and postoperative outcome of pediatric patients with Grade 3 pancreatic trauma injury and asymptomatic COVID-19

The global pandemic of coronavirus disease 2019 (COVID-19) has inevitably affected pediatric surgical services. Clinical manifestations of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in pediatrics are generally asymptomatic to mild, so they are often not detected during initial screening. In adult population, the postoperative mortality of patients infected with SARS-CoV-2 is 23.8%. The possibility of SARS-CoV-2 transmission to health workers during surgery, the increasing postoperative mortality, and the risk of postoperative complications pose challenges for anesthetists in treating pediatric patients with COVID-19 undergoing emergency surgery. Here, we describe the management of anesthesia and postoperative evaluation of a pediatric patient with asymptomatic COVID-19 who underwent emergency laparotomy due to grade 3 traumatic pancreatic injury under general anesthesia. We found no worsening of clinical symptoms or complications related to COVID-19 on 30 days after surgery. The increase in inflammatory markers was not related to COVID-19 but was an inflammatory response to traumatic injury and surgery. © Bali Journal of Anesthesiology 2018.

Orthopedic department of education center and service provide during coronavirus disease-2019 pandemic: An experience from single-center hospital

BACKGROUND: In the global pandemic of the 2019 coronavirus disease (COVID-19), many countries have reported a decrease in visits to hospitals, and health-care systems around the world are reshaping health protocols. Health service and education in orthopedics are also affected although not at the frontline in dealing COVID-19. METHODS: The data from this study collected from several official databases, including the Indonesian Ministry of Health, Central Java provincial government, general hospital, and orthopedic surgery cases. RESULTS: Pandemic COVID-19 started in March 2020 in Indonesia. Surakarta has become one of the epicenters. Health services in the orthopedic department also experienced a decrease cases on all divisions (outpatient clinics, emergency rooms, and inpatients). Mann–Whitney non-parametric comparative test showed significance result in p value operation of orthopedic cases and inpatients (p = 0.016 and p = 0.016;p < 0.05), meanwhile, outpatient visits did not show significance result with p = 0.0509 (p > 0.05). The decrease in the number of cases being treated in the orthopedic service also has an impact on education and training programs. The digital era is one of the choices in the field of education. However, digital resources cannot substitute for direct patient exposure. CONCLUSION: The average number of orthopedic patients during the pandemic period from January to December 2020 decreased compared to visits in the same period in 2019 so that orthopedic services at tertiary and academic referral hospitals experienced a significant decrease in cases. The education and services department must adapt to the policy on educational activities for residents and medical students. The education department and hospital institutions restructured and reorganized resident doctors to continue providing services. The digital era is an option that supports the education process during a pandemic.
