Pembangunan terus terjadi di Kawasan Metropolitan Jakarta (Jabodetabek),ketidakmampuan lahan Jakarta menyediakan tempat bagi setiap masyarakatnyamembuat pembangunan mengarah ke Selatan, Barat hingga Timur hingga berubahmenjadi kawasan konurbasi. Peningkatan pembangunan yang pesat menjadipemicu peningkatan panas perkotaan yang terpusat pada area urban dan terdapatperbedaan suhu dengan wilayah sub-urban sehingga dapat menimbulkanfenomena pulau bahang. Penelitian ini memanfaatkan penginderaan jauh untukmendeteksi suhu permukaan, kerapatan bangunan (NDBI), kerapatan vegetasi(NDVI) dan pemanfaatan citra malam hari untuk mengekstrak city light. Hasilpenelitian menunjukkan adanya pengaruh pembangunan terhadap peningkatanpulau bahang di tahun 2009, 2014 dan 2019 masing-masing bernilai 63 %, 62%dan 56%. Pulau bahang menutup zona budidaya peruntukan pemerintahan,industri dan bisnis sebesar 30 % dari luas kawasan Jabodetabek. Salah satu upayayang dapat dilakukan pemerintah dalam menekan penurunan pulau bahangdengan target 5oC yaitu melalui integrasi penataan kawasan Jabodetabek
Development continues to take place in the Jakarta Metropolitan Area(Jabodetabek), the inability of Jakarta's land to provide a place for each of itspeople has led to development leading to the South, West and East until it hasturned into a conurbation area. The rapid increase in development has become atrigger for an increase in urban heat which is concentrated in urban areas and thereis a difference in temperature with sub-urban areas so that it can cause thephenomenon of hot islands. This study utilizes remote sensing to detect surfacetemperature, building density (NDBI), vegetation density (NDVI) and the use ofnight imagery to extract city light. The results showed that there was an effect ofdevelopment on the increase urban heat island in 2009, 2014 and 2019 with 63%,62% and 56%, respectively. Urban heat island closes the cultivation zonedesignated for government, industry and business as much as 30% of theJabodetabek area. One of the efforts that the government can make in suppressingthe decline of urban heat island with a target of 5oC is through integration of theJabodetabek area arrangement. |
