Estimasi Perubahan Kualitas Udara Berbasis Citra Satelit Penginderaan Jauh Di Sekitar PLTU Cirebon

Abstract

<jats:p>Steam power plant construction and operation is an effort to meet electricity needs. In Indonesia, two steam power plants were built and changed the landscape in Cirebon. The presence of Cirebon steam power plants has disturbed the community and potential to decrease air quality. This study aims to estimate air quality changes around the power plants based on remote sensing satellite imageries. The main data in this study obtained from Landsat-8 OLI (2019) and Landsat-7 ETM (2004) satellite imageries were processed with four parameters of air quality algorithm namely PM10, CO, SO2, and NOx on AOI with ranging of 2000 m from the source point. Validation uses comparative data from MODIS and Sentinel-2 MSS satellite imageries in the same period. Changes analysis in air quality used the Mann-Whitney method (U-Test). This research shows that the Landsat series satellite imagery is suitable to be used as the main data for estimating air quality because it has a similar pattern to comparable data. The Cirebon PLTU operation caused a significant increase in CO levels of 1.25 mg/l on a wide range. In other air quality parameters such as PM10, SO2 and NOx were decreased.</jats:p>

Utilization Eos Platform as Cloud-Based Gis to Analyze Vegetation Greenness in Cirebon Regency, Indonesia

“…Vegetation greenness analysis using the EOS Platform has proven to be effective as an alternative to online and cloudbased GIS image processing. This is evidenced by the results in line with other studies concerning changes in the landscape in Cirebon and surrounding areas due to the construction of settlements, industrial areas, and infrastructures such as coalfired power plants [23]. Even so, at some points on the north coast and surrounding river, it increases in vegetation greenness due to the tree-planting movement carried out by the local government and community.…”

Prediksi Suhu Permukaan Menggunakan Artificial Neural Network-Cellular Automata Di Wilayah Cirebon Dan Sekitarnya

“…Radiative Transfer Equation melalui Persamaan 1 dan Persamaan 2 yang menghasilkan brightness temperature, nilai tersebut kemudian dikonversi dalam satuan derajat celsius sebgai suhu permukaan (ST) (Hasan et al, 2014). Beragam informasi yang dihasilkan dari beragam algoritma untuk citra Satelit Landsar series divalidasi dengan data dari citra satelit lain yang memiliki karakteristik serupa menggunakan pengujian korelasi Spearman-Rank untuk melihat pola nilainya (Persamaan 3) (Dede et al, 2020b Suhu permukaan yang berasal dari citra satelit Landsat series divalidasi menggunakan data dari citra satelit Aster-T1, karena keduanya memiliki thermal band. Prediksi suhu permukaan juga menggunakan sejumlah variabel spasial lain yang berperan sebagai driving force yakni kepadatan bangunan, kerapatan vegetasi, dan kepadatan jaringan jalan.…”

Dampak Fisik Dan Sosial Perubahan Garis Pantai Di Kecamatan Gebang, Kabupaten Cirebon

“…Saat ini, beberapa titik di wilayah pesisir Cirebon Timur seperti Kecamatan Mundu, Astanajapura dan Pangenan digunakan untuk pembangkit listrik tenaga batu bara (PLTU). Keberadaan PLTU menyebabkan perubahan lingkungan akuatik laut di sekitarnya, terutama karena adanya konstruksi dermaga yang memicu terjadinya beban sedimen yang terperangkap dan perubahan arus laut hingga terjadi akresi (Dede et al, 2020). Selain itu, wilayah pesisir Cirebon Timur dimanfaatkan untuk pengembangan pelabuhan tetapi pendangkalan masih terjadi oleh sedimentasi sungai dan mengganggu proyek (Hartanti, 2018).…”
