Problem delay or sampling for print in serial monitor

Yes, if you want the fastest sampling,

in function void loop you can see the program that i was comment

void loop ()
{...
sensor.requestTemperatures();
suhu = sensor.getTempCByIndex(0) * 1.1;  // Ambil hasil konversi
...
}
```emphasized text

do you understand what @lastchancename is discussing

trying calling sensor.requestTemperatures(); after sensor.getTempCByIndex(0)

you may want to call sensor.requestTemperatures(); in setup()

please think about this.

I think when I call sensor.requestTemperatures(); in the setup void it doesn't create a delay, but in the loop void it does.

not sure you understood what lastchancename described

sensor.requestTemperatures() shouldn't create a delay, it should just start a conversion and return immediately.

sensor.getTempCByIndex(0) may be delayed if the conversoin is not completed, but that delay may be shorter because of all the processing that was done between sampling.

there may be a function to determine if a conversion is complete before calling sensor.getTempCByIndex(0) if this delay is still too long
