Clean air is vital for life. Air quality becomes critical and should be preserved. However, the growth of economic activities has had a negative impact on our air quality, specifically air pollution.

That is why we broaden our sensor network so that Indonesian citizens can easily access air quality information in their location. 

We have expanded our network of air quality sensors to three more cities:
Semarang, Surabaya, and Malang. The sensors installed in each city will contribute to our expanding air quality network, which currently includes over 180 sensors in Jabodetabek, Bali, and DI Yogyakarta.


Semarang, one of Indonesia's provincial capitals, is known for its industrial estates. According to the Central Bureau of Statistics, Semarang City currently has seven large industrial estates. These industrial estates are made up of several industries that each run their processes, generating various types of waste and byproducts, one of which is air pollution.

In Semarang, the sensors have been placed in:
Semarang Tengah, Semarang Barat, Bongsari, Ngaliyan, and Gunung Pati.


Surabaya City is the hub of activity for many sectors in the East Java region, including the industrial sector, where many jobs are created. Surabaya has previously been targeted as a location to provide jobs to people from other cities, thereby increasing community mobility. A study states the number of vehicles in Surabaya that run on gasoline is estimated to be almost three million units and the number of diesel vehicles is almost 200,000 units. This packed city is frequently ranked among Indonesia's top ten cities with poor air quality.

In Surabaya, the sensors have been placed in:
Kenjeran, Kedungdoro, Lontar, Medokan Ayu, Krembangan Selatan, Tanjungsari, Tenggilis Mejoyo, Kertajaya, Baratajaya, and Jemur Wonosari.


Malang is well-known as a tourist and educational city with pleasant weather. On the other hand, the city is experiencing rapid economic growth, which is aided by the highway that many vehicles use. The increase in traffic and the shrinking number of open spaces in the city are believed to have led to this situation, which has resulted in unsafe levels of pollution. Based on data from the Malang City Health Office, respiratory infections are among the top five diseases suffered by residents of Malang City. Respiratory tract infection is one of the diseases caused by dirty air inhaled by humans.

In Malang, the sensors have been placed in:
Lesanpuro, Arjosari, Polowijen, Bandulan, and Sekarpuro (Kabupaten Malang).

We hope that by installing sensors in these cities, residents will be more aware of the air quality around them and take better care of their health due to the lifestyle recommendations provided by nafas app.
