Time now in Kelurahan Sumber Jaya

Sunrise today lands at 06:12 and sunset at 06:13 local time, giving 12h 01m of daylight. Those figures come from the city's own coordinates (-3.91, 102.31) rather than a country-wide average, so they match what you would actually see from a window in Kelurahan Sumber Jaya.

If you are coordinating from another country, the shortcut is the working window: a normal Kelurahan Sumber Jaya day of 09:00–17:00 falls between 02:00–10:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.

Kelurahan Sumber Jaya sits at latitude -3.91, in the tropical band, so day length here swings only a little between midwinter and midsummer — today's 12h 01m is one point on that curve, not a fixed value.
