Napas Jakarta
About Napas Jakarta
Napas Jakarta is a free, bilingual map and assistant that helps people read Jakarta's air-quality data. It shows readings from official monitoring stations and explains what they mean, in English and Bahasa Indonesia, with no account required.
Who is Napas Jakarta for?
Residents, commuters, parents, students and anyone who wants to understand a station reading instead of only seeing a number. It is built to answer practical questions: what a value means, how recent it is, where it came from, and what to check next.
Where does the data come from?
Station observations come from the official DKI Jakarta air-quality monitoring portal. Each reading keeps its station name, observation time and a link back to the source so you can verify it. Napas does not operate monitors or measure air quality itself.
The data is refreshed from the portal on a schedule, currently every two hours. The observation time on each reading, not the refresh time, tells you when the air was measured.
How does Napas handle old or missing readings?
A reading counts as current only if it was observed within the last 24 hours. Older readings are labelled stale and always show their observation time. Some stations stop reporting for days; they keep their last reading but are marked stale, and the summary counts only stations with a recent reading.
A missing value is shown as unavailable, never as zero.
How does the assistant answer questions?
The assistant answers from station data and curated official sources, such as government guidance and World Health Organization guidelines. It keeps a single station's reading separate from wider city context, shows the observation time and source, and cites sources where they are available. When the evidence is not there, it says so instead of guessing. It does not diagnose symptoms or give medical advice.
What can't Napas tell you?
- A station reading describes that station and that time only. It is not a citywide average.
- ISPU and pollutant concentrations such as PM2.5 are different kinds of value. Napas does not silently convert between them.
- Historical charts are city-level modelled context, not official station history.
- WHO guideline values are health-based recommendations, not Indonesian legal thresholds.
- Napas is an educational information tool, not an official warning service or a medical device.
