The coronavirus disease (COVID-19) pandemic has affected people’s lives globally. Indonesia has been significantly affected by this disease. COVID-19 has also affected certain social and economic aspects of Indonesia, including community resilience. Through a variety of contexts and geographic locales, we explore the previously mentioned concept of resilience. From existing literature reviews, we develop a holistic framework for community resilience during the COVID-19 pandemic. Then, we formulate crucial factors for community resilience during the COVID-19 pandemic: natural capital, social capital, human capital, stakeholder engagement, community participation, technology, and communication. Strategic stakeholder action in the community resilience domain has facilitated increases in economic as well financial capital for adapting to and surviving deficits in productivity in the face of the COVID-19 pandemic. This study is a reflection on and a comparative review of the existing literature from different countries.

The present study aimed to identify the nutritional and antioxidant potential of mangrove fruits of Xylocarpus granatum, Sonneratia alba, and Bruguiera gymnorrhiza growing in Rawa Aopa Watumohai National (RAWN) Park. The protein content of X. granatum fruits (4.50 mg/g) was recorded to be higher than that S. alba (0.93 mg/g) and B. gymnorrhiza (1.09 mg/g), while the fat content in fruits of X. granatum (4.88%), S. alba (4.42%), and B. gymnorrhiza (4.74%) was similar. The total sugar content in fruits of X. granatum (14.8 mg/100 g), S. alba (14.9 mg/100 g), and B. gymnorrhiza (13.52 mg/100 g) was also similar. The ascorbic acid content in X. granatum fruit (65 mg/100 g) was higher than that in S. alba (40 mg/100 g) and B. gymnorrhiza (41.87 mg/100 g). However, the fruits of S. alba contained much higher micronutrients of Mn (0.063 mg/g), Zn (0.72 mg/g), and Fe (0.51 mg/g) than those of in X. granatum (0.052, 0.52, and 0.38 mg/g, respectively), and B. gymnorrhiza (0.012, 0.11, and 0.34 mg/g, respectively). Moreover, the fruits of X. granatum contained much higher macronutrients of K and Na compared to fruits of other mangroves. Thus, the findings of this study showed the promising values of all studied mangrove fruits as bio-nutrition and antioxidant sources, and high potentiality to use as renewable food sources for the coastal communities in RAWN Park.

Planktonic organisms are the main biotic components of the food chain of aquatic ecosystems. Little is known about the impact of multiple stressors on plankton community response in mining areas. This study aimed to elucidate the alpha diversity of zooplankton and phytoplankton in different stream networks associated with mining activities in the Molore watershed, Southeast Sulawesi. The research was carried out by taking samples for water quality and plankton analyses in four streams in November 2021 and November 2022. A rarefaction curve approach was used to assess the species richness and diversity trends of the region. Streams were clustered using the Bray-Curtis similarity index of alpha diversity indices, such as the Shannon-Wiener, Simpson, Margalef, Pielou, and Berger-Parker indices. We found six species of zooplankton only in three sites and 21 species of Phytoplankton in the class of Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, and Euglenophyceae across the landscape gradient. The present study showed that the lowest value of the Shannon-Wiener diversity of the plankton community was 0.48, while the maximum expected value based on individuals’ rarefaction curve was 2.24. Species richness is in line with cluster analysis, which shows the similarity of stream groups according to the level of environmental pressure, indicating a valuable ecological indicator for stream management.

The present study was aimed to elucidate the spatial pattern in the beta diversity of marine bentic for Echinoidea and Asteroidea that assemblages the coastal area of Tomia Island, Wakatobi Marine National Park, Indonesia. The two transect lines of 460 and 260 m in length with small quadrats of 1m2 wide were placed at the open and unopen beaches perpendicularly to the coastlines. The important value index and similarity index SI of organisms on these taxa were estimated in each the transect. Echinometra mathaei was the most dominant Echinoidea at open and unpen beaches, while Protoreaster nodusus was the most dominant Asteroidea at both areas. Most of SI values of Echinoidea at open beach were estimated less than 50%, which was lower than SI values that of organisms at unopen beach. On the other hand, most of SI values of Asteroidea at both areas were estimated more than 70% representing high similarity degree of its species composition among sites. The disimilarity index of organisms in the taxa of Echinoidea and Asteroidae was increased significantly as increasing the distance of among stands, which suggested that pettern in beta diversity of these taxa was associated with the spatial heterogenity.
