		abstract={Transportation of garbage in Purwokerto has been carried out 2-3 times in 1 week
for each trash can. Waste that is left too long piles up in trash can because irregular
transportation is a frequent problem. Therefore, the authors make smart bins that can
monitor the height of garbage through an application on Android to overcome the
problem of accumulating garbage in a trash can. This system uses an ultrasonic sensor to
detect the height of garbage that will be processed in the NodeMCU, NodeMCU will
update the time in real time once every second through the NTP server. If the time shows
8 o'clock in the morning, the data will be sent to the IFTTT (If This Then That) Applets
according to the identity of the trash, using the address of the key and event that has been
created. Then the event will occur in the IFTTT Applets, Webhooks accepts web requests
from IFTTT. IFTTT will send a message to the Line and Facebook Messenger
application, in the form of garbage height in accordance with the identity of the trash. If
the garbage height > = 16 cm LED is lit, then if the garbage height <16 cm LED is off.
The results of this study show that the difference in measurement of ultrasonic sensors
with a ruler of 30 cm is 0.19 cm to 0.27 cm and the average error of measurement with an
ultrasonic sensor is 2.76%, the format of filling garbage in 3 bins with notification on the
Smartphone is the same , when sending smart trash notifications to Smartphones, which
are 4.52 seconds to 5.6 seconds, the throughput value on data sent by smart bins to
smartphones is 56,27 bits / sec to 68,13 bits / sec, and the compatibility between the times
of smart bins sends data with notification time up to the corresponding Smartphone.
