WHAT IS 'STATE OF EMERGENCY'?
An emergency status allows the city's administration to deploy available resources including personnel and take mitigation measures by purchasing medical equipment and carrying out tests for Covid-19, the disease caused by the new coronavirus, by tapping the city's funds.
Besides Jakarta, at least six of 34 provinces across the country have declared a state of emergency.
They are: Yogyakarta, West Java, East Java, Banten, West Kalimantan, East Kalimantan.
WHAT HAPPENS DURING THE EMERGENCY?
While it is not a lockdown, the Jakarta administration is curbing the movement of people to and from the capital by shortening the operating hours of public transportation such as buses and intercity trains.
MRT Jakarta service hours have been cut by five hours, and now operates from 6am to 8pm.
Taxis and ride-hailing services, however, operate as usual.
From Monday (March 23), entertainment centres, including bars, massage parlours, spa centres, cinemas and billiard saloons, are shut.
Companies have been urged to close offices and allow their employees to work from home. Firms which are unable to shutter must reduce their activities and the employees working in the offices to key personnel.
However, there is no penalty for non-compliance.
Tourist sites such as the zoo and museums have been closed for two weeks since March 14. Schools were closed on Mar 16 for two weeks as well, and will reopen on March 30.
Shopping malls, supermarkets and wet markets will remain open.
Although some civil servants are allowed to work from home, government services are unaffected.
While there is no curfew, people are expected to reduce their activities and stay, study and worship at home.
Jakarta police have been called upon to disperse crowds at weddings and private parties.
WHAT ARE SOME OTHER MEASURES BEING TAKEN ?

The national government has bought 5,000 Avigan pills - an anti-influenza drug - and placed orders for two million more.
It is also preparing to secure three million chloroquine pills, typically used to treat malaria but which has been touted by some as a possible treatment for Covid-19.
Indonesia has taken delivery of about 150,000 testing kits from China, and plans to procure around 1 million more.
Exports of masks, protective personal equipment and antiseptics have been banned.
There are insufficient hospitals, healthcare workers and medical equipment to treat Covid-19 patients in the country.
