Abstract

Sentinel-2 Data Analysis to Support Special Interest Tourism in the Wakatobi Region Abstract. Tourism has a role for power improvement of the regional economy; therefore, it is important to do a good plan, management, and monitoring the tourism areas for sustainable goals. Satellite-based remote sensing methods are proven reliable in getting area information effectively and regularly. The Sentinel-2 satellites monitoring land cover changes regularly thus that it can be used to analyze the environmental carrying capacity for tourism. Sentinel-2 data that consists of several scenes at two-time observations were processed by mosaicking and spectral color composite strategies. The Wakatobi coastal uniqueness was analyzed by the vegetation index method combined with tidal data. There are several regions that were indicated to have spectral changes over five months, with an area approximately 30,55 km2. These interesting objects have the potential to support tourism in the Wakatobi region.

Abstract

Monitoring of SO2 Gas Concentration Around Mount Sinabung Using Sentinel-5 Precursor Satellite Imagery Abstract. Mount Sinabung is a mountain type A that is still active. Mount Sinabung is located in North Sumatra Province, Karo Regency. Mount Sinabung eruption does affect not only the region but also the area around the mountain. One of the substances that were sprayed by the volcano during the outbreak was SO2 gas. SO2 gas is an essential parameter for determining air quality. SO2 gas is in the atmosphere through a natural process and anthropogenic process. The data of SO2 gas was obtained by utilizing the Sentinel-5P record results. Data Sentinel-5P was processed and analyzed to be able to determine the SO2 gas concentration in the area surrounding Mount Sinabung and also changes in the SO2 gas concentrations in several areas. In general, the highest SO2 gas concentration was at the crater of Mount Sinabung. However, on 22 July 2019, the SO2 gas concentrations in Deli Serdang Regency were higher, around 75% of SO2 gas concentrations in the crater area. This research may also indicate that Sentinel-5P data can be used to monitor gas in the atmosphere. Keywords: Mount Sinabung; Eruption; SO2; air quality; Sentinel-5P.

Abstract

Variations of Nitrogen Dioxide Emissions during Large Scale Social Restrictions in West Java Province from Sentinel-5P Satellite Data Processing Abstract. Sentinel-5P satellite that was launched in 2017 by ESA has a mission to monitor the earth’s atmosphere. One product of Sentinel-5P mission is the distribution of troposphere column density for several gases including nitrogen dioxide (NO2). NO2 emission is related to fossil fuel combustion from human activities such as factories and vehicle emissions. In 2020, COVID-19 is spreading all over the world including Indonesia. To break the chain of its distribution, therefore, the Indonesian Government enacts large scale social restriction (PSBB) in several areas including West Java Province. Sentinel-5P data was processed and analyzed to see the variations of changes in NO2 emission in several sampled cities in West Java. It is found that the NO2 emissions have decreased during PSBB. However, before Idul Fitri event on May 18, 2020, shows that the NO2 emission at Bandung Cities, Bandung District, and Bogor District increase significantly up to six-time higher. This activity also shows that daily information from Sentinel-5P satellite can be used for monitoring gases in the atmosphere.
