Abstract:
Technology is needed in every industry because it can simplify the production process, improve production
quality, and enhance the company's reputation in the sight of consumers. The cylinder counting activity at PT
Batuah Energi Indonesia is still done manually, involving time and standardized estimation of LPG cylinder loads,
which faces inaccuracy issues. In fact, PT Batuah Energi Indonesia has facilities that handle many LPG cylinders
from various users and providers of LPG cylinders. While accurate cylinder counts are beneficial to the industry,
companies need technology that can automatically calculate the number of filled LPG cylinders. Therefore, this
study was carried out to demonstrate to students how to develop automatic tube counters using an infrared E18D80NK
as
a
tube
detector,
NodeMCU
microcontrollers
ESP8266
as
controllers,
Arduino
IDE
for
developing
programs,
and
IoT
for
remote
monitoring.
The
developed
device
approach,
specifically
using
the
E18-D80NK
infrared
proximity
sensor
based
on
the
NodeMCU
ESP8266,
can
be
coded
using
the
Arduino
IDE
compiler.
For
the
detection
of
the
number
of
tubes,
the
E18-EN80K
infrared
sensor
is
used
and
data
transmission
wirelessly
utilizes
the
Blynk
application.
The
results
of
the
automatic
tube
counter
monitoring
tool
were
successfully
tested
with
a
100%
accuracy
rate,
utilizing
the
E18-D80NK
infrared
sensor
and
NodeMCU
microcontroller
ESP8266,
and
can
be
monitored
remotely
using
Blynk.
