dc.description.abstract | Pemantauan tebal lapisan minyak penting dilakukan karena mempengaruhi
kadar kotoran di overflow. Saat ini pengukuran tebal lapisan minyak pada tangki
CST masih dilakukan secara manual oleh operator menggunakan selang bening
atau gelas penduga. Data pemantauan diukur setiap 2 jam sekali oleh operator di
atas tangki yang panas. Data yang dihasilkan tidak kontinu, input data secara
manual, serta mengharuskan operator hadir secara on-site. Pengukuran tebal
lapisan fluida dapat digantikan dengan penggunaan kamera atau dengan sensor
berat menggunakan load cell. Penelitian ini bertujuan merancang bangun model
sistem monitoring ketebalan lapisan fluida pada tangki CST dengan berbasis IoT.
Penelitian ini terdiri beberapa tahapan, antara lain : Identifikasi dan perumusan
masalah, perancangan fungsional sistem monitoring, perancangan struktural
hardware, pengujian dan kalibrasi hardware perancangan arsitektur software, dan
pengujian kinerja sistem monitoring. Hasil pengukuran membuktikan variasi
metode pengolahan citra tanpa objek referensi memiliki kinerja terbaik diukur dari
akurasi 95,7%, durasi olah data 0,04 detik, durasi transfer data 2,5 detik, dan
komponen yang lebih sedikit, namun metode ini sensitif terhadap perubahan
posisi kamera. Penambahan objek referensi mampu mengkompensasi perubahan
posisi kamera, namun pendeteksian objek referensi yang tidak tepat menyebabkan
rendahnya akurasi yaitu sebesar 88,91% dan peningkatan durasi olah menjadi 0,09
detik. Metode displacer dapat diterapkan, apabila tidak memungkinkan
pengolahan citra dilakukan. Metode displacer tunggal berkinerja cukup baik
dengan akurasi hingga 90,05% dengan diameter 50 mm, namun metode displacer
tunggal sensitif terhadap perubahan suhu sehingga membutuhkan pengkoreksi
dari persamaan densitas atau dari displacer kalibrasi. Penggunaan displacer
kalibrasi dan persamaan densitas terbukti mampu mengkompensasi perubahan
suhu fluida. Data pengukuran tersebut disimpan pada server Google Spreadsheet,
kemudian ditampilkan pada aplikasi monitoring yang telah dibuat. | id |
dc.description.abstract | Monitoring the thickness of the oil layer is important because it affects the
level of dirt in the overflow. Currently, the measurement of the thickness of the oil
layer in the CST tank is still carried out manually by the operator using a clear
hose or measuring cup. Monitoring data is measured every 2 hours by the operator
on a hot tank. The data generated is not continuous, input data manually, and
requires the operator to be present on-site. The thickness measurement of the fluid
layer can be replaced by the use of a camera or by a weight sensor using a load
cell. This study aims to design a model of a fluid layer thickness monitoring
system in a CST tank based on IoT. This research consists of several stages,
including: Identification and formulation of problems, functional design of
monitoring systems, structural hardware design, hardware testing and calibration
of software architecture design, and monitoring system performance testing. The
measurement results prove that variations in image processing methods without
reference objects have the best performance measured from 95.7% accuracy, data
processing duration 0.04 seconds, data transfer duration 2.5 seconds, and fewer
components, but this method is sensitive to changes in position. camera. The
addition of a reference object is able to compensate for changes in camera
position, but the detection of an inappropriate reference object causes a low
accuracy of 88.91% and an increase in processing duration to 0.09 seconds. The
displacer method can be applied, if it is not possible to do image processing. The
single displacer method performs quite well with an accuracy of up to 90.05%
with a diameter of 50 mm, but the single displacer method is sensitive to changes
in temperature so it requires correction of one of them with a calibration displacer.
The use of a calibration displacer in the double displacer method is proven to be
able to compensate for changes in fluid temperature. The measurement data is
stored on the Google Sheets server, then displayed on the monitoring application
that has been created. | id |
