Abstract

Covid-19 became a global pandemic in 2020 and has multiple impacts on the economy, social, culture, food systems, and also the environment, especially on tropical forest cover in small island. This study aims to determine the impact of the Covid-19 pandemic on the forest cover of small populated islands. Using remote sensing and geographic information system technology based on high-resolution satellite imagery from google earth imagery, land cover was observed in 2018, 2020, and 2023. This study found that during the 2020 pandemic, tropical forest cover on small populated islands has decreased. Mansinam's forest cover decreased by 4.3%, bare land increased by 80.6%, agricultural land increased by 75.3%, and shrubs increased by 54.9%. Another important finding is that 78.9% of the total deforestation was due to forest conversion to bare land and agricultural land. Land and forest utilization on small islands will increase when accessibility is limited, especially during the pandemic. Future studies will be on the structure and composition of species in locations that experienced deforestation during the pandemic and detailed studies related to changes in the occupations of Mansinam people due to the pandemic that have a relationship with forests.

Abstract

Cuscus (Spilocuscus maculatus) in captivity that were given a dominant fruit diet needed additional feed from their natural habitat because of the higher nutritional potential and fiber components. This study aims to determine the palatability of cuscus to the feed based on organic value. An experimental method was used, consisting of 4 treatment groups: 100% banana (Musa paradisiaca) as control, 70% banana mixed with 30% matoa (Pometia pinnata) leaves, 70% banana mixed with 30% ironwood (Pongamia pinnata) leaves, and 70% banana mixed with 30% crickets (Gryllus bimaculatus). The results showed that banana was the most preferred feed ingredient, either alone or as a supplementary feed mixture. In terms of quantity, its mixture with matoa leaves had a higher consumption level than ironwood leaves and crickets. The consumption level of organic matter was higher in the treatment with 100% banana than in other treatments. This information will help support ex-situ and in-situ conservation programs formulated by the government and other parties, including the community.
