Abstract

Telah dilakukan rancang bangun dari sistem konveyor pada penggiling padi yang
berfungsi menggantikan manusia untuk memindahkan atau mengangkat padi ke
corong mesin penggiling. Alat ini dilengkapi dengan sistem kontrol laju aliran padi,
sensor ultrasonik, sensor optocoupler, dan motor DC. Metode kontrol yang
digunakan dalam alat tugas akhir ini adalah PWM (Pulse With Modulation). Sistem
pengukuran level padi, dan kecepatan motor pada alat Tugas Akhir ini
menggunakan sensor ultrasonik dengan akurasi 93.6%, sensitivitas 0.042, dan ratarata error 6,98% untuk pengukuran level padi pada bucket dan sensor optocoupler
dengan akurasi 96.8%, sensitivitas 0.2, dan rata-rata error 3.15% yang berfungsi
untuk mengukur kecepatan putar dari motor penggerak belt conveyor. Semua data
ini ditampilkan pada HMI secara wireless dengan modul Wi-Fi dan berbasis Blynk.
Melalui modul Wi-Fi dan aplikasi Blynk ini, operator dapat mengendalikan
prototipe dengan set point yang diinginkan. Performa sistem kontrol mass flow rate
padi pada alat ini sudah cukup baik dibuktikan dengan rise time pada set-point 5
Kg/mnt, 10 Kg/mnt, 15 Kg/mntpada 15 Kg/mnt adalah 13,85%. Untuk performa
terbaik dari sistem terdapat pada saat set point 15 Kg/mnt dibuktikan dengan nilai
rise time 3,5 sekon, maximum overshoot 13,85%, settling time 3,5 sekon – 22 sekon,
dan error steady state 2,7%.
=================================================================================================
The design of the conveyor system on the rice grinder has been carried out which
functions to replace humans to move or lift rice to the grinding machine funnel.
This tool is equipped with a rice flow rate control system, ultrasonic sensor,
optocoupler sensor, and DC motor. The control method used in this final project is
PWM (Pulse with Modulation). The rice level and motor speed measurement system
in this Final Project uses an ultrasonic sensor with an accuracy of 93.6%, a
sensitivity of 0.042, and an average error of 6.98% for measuring rice level on a
bucket and optocoupler sensor with an accuracy of 96.8%, sensitivity 0.2, and an
average error of 3.15% which serves to measure the rotational speed of the belt
conveyor driving motor. All this data is displayed on the HMI wirelessly with the
Wi-Fi module and is Blynk based. Through this Wi-Fi module and Blynk
application, operators can control the prototype with the desired set point. The
performance of the rice mass flow rate control system on this tool is quite good, as
evidenced by the rise time at set-point of 5 Kg/min, 10 Kg/min, 15 Kg/min at 15
Kg/min was 13.85%. For the best performance of the system, there is a set point of
15 Kg/min as evidenced by the rise time value of 3.5 seconds, maximum overshoot
of 13.85%, settling time of 3.5 seconds - 22 seconds, and steady-state error of 2.7%.
