dc.description.abstract | Bulking menjadi permasalahan pada pengolahan limbah cair. Analisis terkait
karakteristik sedimentasi penting dilakukan untuk menghindari fenomena tersebut,
terutama sedimentasi dengan karakteristik hindered dan compression settling.
Pemodelan laju pengendapan hindered dan compression settling dilakukan untuk
mengetahui metode terbaik dalam analisis kecepatan pengendapan sedimen air lindi
menggunakan tiga metode antara lain Kynch, Robert’s derivation, serta Dick and
Vesilind. Hydraulic Retention Time (HRT) unit kontak divariasikan menjadi 1 jam,
2 jam, dan 3 jam, sedangkan HRT unit stabilisasi divariasikan menjadi 4 jam, 5 jam,
dan 6 jam. Hasil penelitian menunjukkan bahwa metode Kynch dan Robert’s
derivation memiliki nilai Akaike Information Criterion (AIC) terendah pada variasi
1 dan 3, sedangkan metode Dick and Vesilind memiliki nilai AIC terendah pada
variasi 2 dan 4. Nilai AIC pada variasi 5 untuk kedua metode bernilai sama.
Pemodelan menggunakan metode Kynch, Robert’s derivation, maupun Dick and
Vesilind tergolong valid pada pengamatan sedimen air lindi. Namun, perolehan
nilai AIC pada kedua metode di tiap variasi tidak memiliki perbedaan nilai yang
signifikan sehingga metode Dick and Vesilind bisa digunakan sebagai pemodelan
terbaik pada tiap variasi . | id |
dc.description.abstract | Bulking becomes a problem in wastewater treatment. It is important to
analyze sedimentation characteristics to avoid this phenomenon, especially
sedimentation with hindered and compression settling characteristics. The
modeling of hindered and compression settling rates was carried out to find out the
best method for analyzing the sedimentation rate of leachate using three methods,
namely Kynch, Robert's derivation, and Dick and Vesilind. Hydraulic Retention
Time (HRT) of contact unit was varied into 1 hour, 2 hours, and 3 hours, while HRT
of stabilization unit was varied into 4 hours, 5 hours, and 6 hours. The results
showed that the Kynch and Robert's derivation methods had the lowest AIC values
in variations 1 and 3, while the Dick and Vesilind method had the lowest AIC values
in variations 2 and 4. The AIC values in variation 5 for both methods were the same.
Modeling using the Kynch, Robert's derivation, and Dick and Vesilind methods are
valid for leachate sediment observations. However, the acquisition of AIC values
in the two methods in each variation did not have a significant difference in value
so that the Dick and Vesilind method could be used as the best modeling for each
variation. | id |
