Social resilience is the ability of community to cope the external stress that related with ecological/environmental changes. Ecological resilience is how fast environment could recovery from the incoming substance and could support community livelihood in that area. There is a clear link between social resilience and ecological resilience, especially for community that dependent on natural resources for their livelihood. This is preliminary study that will examine how social resilience could affect by ecological changes. Within this context, we explore the shock and adaption in Kepulauan Seribu Regency (DKI Jakarta Province) and Takalar Regency (South Sulawesi Province), Indonesia – a coastal community that using seaweed farming as their livelihood. This study presents a literature review and in-depth interview approach to explain more about how seaweed farmer can survive from the ecological changes and what is the alternative livelihood for their sustainability in that area. Seaweed cultivation is one of the coastal community livelihoods that dependent on natural resources and ecological condition. Seaweed cultivation has given a positive impact to local economic condition of coastal community but the changes of ecological condition could directly affect seaweed productivity. Ecological resilience in coastal area is how fast they could recovery from the incoming substance and always support community livelihood in that area. The quickness of ecological recovery is related to how much; and how long; and extensive the effect of incoming substance. Seaweed cultivation in Panggang Island (one island in Kepulauan Seribu islands) has started since 1986. The cultivation become booming since there are a high price of seaweed in this area. In 2000, there are Hugh reductions of seaweed production in Kepulauan Seribu. Farmers have tried to replant the seaweed but always failed. The new seed is become damaged and rotten. Since that time, there was no seaweed cultivation in Kepulauan Seribu. In 2013, one of the farmers in Kepulauan Seribu begins to try to grow seaweed. Seaweed seed start to grow well in mid-2014. According to the farmers on Panggang Island, successes and failures of seaweed cultivation is affected by changes in the harvesting season. In Takalar, production of seaweed cultivation constrained by environment factors like monsoon; urban development that causes water pollution; and issues about “land” ownership.
The Medical Geographic Information System (Medical GIS) application during the COVID-19 pandemic crisis has become influential in communicating disease surveillance for health practitioners and society. The Johns Hopkins University has extensively used a well-known Web-GIS dashboard to track the COVID-19 cases since January 22 and illustrates the location and number of confirmed COVID-19 cases. Unfortunately, the dashboard particularly for Indonesian cases is only represented by one point (dot map) placed on the centroid of the Indonesian archipelago. Further research can fill the gap in downscaling the geographical location data of COVID-19 cases to the cities or even the village level in Indonesia and communicating the susceptible zoning to society. We uplift the point COVID-19 cases data to susceptible zoning gathered from official COVID-19 government websites, process it using Geographic Information System analysis, and communicate it to society through a Web-GIS dashboard. Five datasets, i.e., population data, administrative boundary, Landsat 8 OLI satellite imagery, COVID-19 cases geographic location, transportation infrastructure, and crowded places location, are used to analyze the susceptible area. Due to different standard data sources from each province in Indonesia, we only present provinces in Java Island with complete COVID-19 cases data on villages-scale. The technical challenges and future improvement in developing the national dashboard of Web-GIS-based susceptibility dashboard are also discussed. The dashboard information would further add some essential information for society to explore their zone status in adapting to the "New Normal" using the SICOVID-19 dashboard from their computers or gadgets during the pandemic crisis.
Badan Nasional Penanggulangan Bencana (BNPB) mencatat sejak tahun 2017 awal tahun 4 Desember 2017 sebanyak 577 kejadian longsor di Indonesia. Tanah longsor juga menimpa salah satu kecamatan yang ada yaitu di Kecamatan Aranio, Kabupaten Banjar, Kalimantan Selatan yang menyebabkan kerugian material. Banyak faktor yang dapat menyebabkan tanah longsor seperti topografi, penggunaan lahan, dan kerapatan vegetasi. Pembangunan untuk pemukiman dan sektor pertanian di daerah lereng yang curam dapat memicu potensi longsor. Vegetasi memainkan peran penting untuk mencegah terjadinya longsor. Oleh karena itu, untuk mengantisipasi insiden korban jiwa dan kerugian material lebih banyak di Kecamatan Aranio, perlu dilakukan penelitian untuk memperoleh potensi daerah longsor. Dalam penelitian ini dilakukan identifikasi potensi longsor menggunakan metode Slope and Morphology (SMORPH) dengan menerapkan morfologi lereng dan sudut / gradien menggunakan ArcGIS 10.1, sedangkan untuk kerapatan vegetasi citra Landsat 8 menggunakan metode NDVI. Dari hasil penelitian ini ditemukan bahwa daerah potensial longsor tersebar merata di selatan, tengah, dan utara Kecamatan Aranio yang mendominasi di selatan tepatnya di Tiwingan Lama dan Desa Aranio. Ada hubungan antara kerapatan vegetasi dan tingkat potensi longsor sebesar 14%. Vegetasi yang lebih padat dengan batang tanaman besar dan akar yang kuat, memiliki potensi longsor lebih rendah, dan sebaliknya. Kerapatan vegetasi tanaman tertentu dapat menjadi salah satu solusi untuk mencegah insiden korban dan kerugian material oleh tanah longsor.
Mangrove ecosystems in Karawang regency have a fairly extensive mangrove forest with various ecology functions based on conservation that can be used as ecotourism. This can be utilized as a local natural potential by being managed by the community. The purpose of this study was to analyze community perceptions of potensial mangrove ecotourism in Cilebar District are scattered in Pusakajaya Utara and Mekarpohaci villages, while Tempuran sub-districts are scattered in Tanjungjaya and Sumberjaya villages. Data was collected through field surveys and interviews using questionnaires. The analysis used in this research is spatial and descriptive. The result showed that the community perception was very good in the Pusakajaya Utara and Sumberjaya villages; while the community perception was good in Mekarpohaci and Tanjungjaya villages. The better community perception of mangrove ecotourism can be the basis for community participation to manage the potential of the mangrove ecosystem in the area.
<span>Landslides are a common type of disaster in Indonesia, especially in steep-slope areas. The landslide process can be well understood by measuring the surface deformation. Currently, there are no practical solutions for measuring surface deformation at landslide locations other than field surveys in the Pacitan Regency. We apply LiCSBAS, to identify surface deformation in several landslide locations in a specific non-urban area with mixed topographical features. LiCSBAS is a module that utilizes data from the project of looking inside the continent from space (LiCS), using the new small baseline area subset (NSBAS) method. This study utilizes the leaf area index (LAI) to validate the ability of LiCSBAS to detect surface deformation values at landslide locations. The study succeeded in identifying surface deformations at 100 landslide locations, with deformation values ranging from 15.1 to 10.9 millimeters per year. Most of the landslide locations are closely related to volcanic rocks and volcanic sediments on slopes of 30–35°. The NSBAS method in the LiCSBAS module can reduce gaps error in the sentinel-1 image network. However, the utilization of the C-band at a pixel size of 100 meters made surface deformation only well detectable in a large open landslide area.</span>
