Abstract

Bencana kebakaran hutan dan lahan gambut tropis sering diakibatkan karena lahan gambut tropis menjadi kering akibat perubahan kondisi tata air. Sehingga perlu dilakukan pembasahan lahan gambut dengan membuat sekat kanal yang bertujuan untuk menjaga kondisi tata air lahan gambut. Tujuan penelitian ini adalah melakukan uji model fisik sekat kanal, untuk mengetahui stabilitas sekat kanal terhadap gerusan, yang terjadi akibat kecepatan aliran air yang melewati bangunan sekat kanal untuk waktu tertentu, dengan memvariasikan tinggi muka air pada bagian hilir sekat kanal, dan muka air di hulu sekat dalam kondisi tetap. Pada penelitian ini, dilakukan dengan 2 skema pengujian pada model fisik sekat kanal dari beton. Pada skema 1, tinggi muka air di hulu sekat kanal (H1) = 22 cm dan tinggi muka air di hilir sekat kanal (h1) = 10,2 cm, untuk variasi kecepatan aliran (v1) = 0,01 m/dt, (v2) = 0,02 m/dt, serta untuk variasi waktu (t1) = 3 jam, (t2) = 6 jam. Pada skema 2, (H1), (h), (v1), (v2), (t1), (t2), nilainya sama pada parameter skema 1, yang berbeda hanya tinggi muka air pada bagian hilir sekat kanal (h2) = 22 cm. Hasil yang didapat dari penelitian ini adalah kedalaman gerusan yang terjadi di bagian hilir sekat kanal dari beton, sangat dipengaruhi oleh tinggi muka air di hilir, kecepatan aliran air dan waktu

Abstract

Peat soil has a wet and soft texture. Degraded peatlands due to reduced water content will cause drought andhave the potential for fires. One way to overcome the drought is by wetting the peat, namely by building canalblocks. This study aims to determine the effect of different hydrostatic pressure height on seepage discharge.The methods used are documentation, observation, and quantitative data analysis. This research is located inthe city of Palangka Raya carried out from April 10 – May 7 2022. The data analysis technique used is theanalysis of the coefficient of determination on the graph of the effect of the hydrostatic pressure difference onseepage discharge. The initial stage of this research was to collect the data needed to design a concreteconstructed canal blocking prototype. The building is scaled from prototype to distortion model where the scale used is 1:10 on the vertical and 1:25 on the horizontal. In testing the physical model of canal blocking, the test time for observing seepage that occurs in the flume is carried out within 240 minutes where observations are made 30 minutes for each seepage. In the final stage, a model test was carried out with variations in the water level at the upstream being 30 cm and at the downstream the water was empty, without any flow velocity. Based on the results of the model test, it shows that the smaller the hydrostatic pressure difference (ΔTTH) the smaller the seepage discharge value. The results of the largest and smallest seepage discharges in this study were 45 cm3/s at 100% ΔTTH and 11,9 cm3/s at 46% ΔTTH.

Abstract

Forest and land fires are one of the most concerning incidents. One effort to overcome this problem is to reblocktheexistingcanalsusingablock/damsystem.Itishopedthatthewaterlevelinthecanalsonpeatlands canbeincreasedsoastoreducetheriskoffiresduringthedryseason.However,theinformationavailable regarding canal blocking is still very limited. This study aims to determine the stability of canal blockingstructures against shear, stability of overthrowning force and seepage by conducting physical model tests.This research method uses the observation method. The research location was carried out in the city ofPalangka Raya, starting from March 19 2022 to May 24 2022. This research was carried out by directlyobserving the changes that occurred in the physical model of canal blocking. The results showed that thestability against sliding and stability of overthrowning force was stated to be safe. Seepage continues tooccur in the downstream part of the canal blocking, whose value increases with the increase in the waterlevel in the upstream section as time increases.
