[The Jakarta Post]: Surabaya, East Java, and Surakarta, Central Java, are the two cities with the cleanest air in Indonesia, the Environment Ministry announced on Wednesday. The two cities beat 24 other cities in the ministry’s Langit Biru (Blue Sky) program, which rated cities’ air quality based on four main considerations. “The four main parameters were traffic management, the quality of fuel, the result of vehicle emission examination and the air quality on the main roads of each city,” deputy minister for environment pollution control MR Karliansyah said, as quoted by kompas.com. Other additional parameters, she said, were the efforts of local administrations to reduce emissions and the urban planning of respective cities. The ministry divided the 26 cities into the two categories of “metropolitan” and “big city”, each consisting of 14 and 12 cities, respectively. Surabaya, scoring a cumulative index point of 7.21, was chosen as the city with the best air quality in the metropolitan category, followed by Medan, North Sumatra, in second and East Jakarta in third. The big city category saw Surakarta coming out on top with a score of 8.42, beating second place Batam, Riau Islands, and third place Malang, East Java. In the overall standings, the top three cities with the best air quality were Surakarta, Batam and Malang, while the bottom three spots were occupied by Semarang, Bekasi and West Jakarta. Environment Minister Balthazar Kambuaya said that the program was considered a free promotion for cities and was hoped to push local administrations, companies and the general public to care for the air in their respective cities.
