Abstract

Lahan gambut Desa Tanjung Taruna, Kalimantan Tengah difungsikan salah satunya sebagai perkebunan sawit. Peralihan fungsi tata guna lahan dapat mempengaruhi sifat-sifat fisik gambut, mengakibatkan perubahan pergerakan air di dalamnya. Sehingga, perlu diketahui karakteristik gambut pada penggunaan lahan untuk perkebunan sawit berupa konduktivitas hidrolik, bulk density, porositas dan water content serta hubungan antar parameter tersebut. Pengambilan data dilakukan dengan mengambil sampel tanah di lapangan kedalaman 0–50 cm, 50–100 cm dan 100–150 cm arah vertikal dan arah horizontal, selanjutnya dianalisis untuk mengetahui konduktivitas hidrolik (K), bulk density (BD), porositas (P) dan water content (WC). Pada lahan gambut tropis yang penggunaan lahannya berupa perkebunan sawit, diperoleh nilai K arah vertikal paling besar pada kedalaman 50-100 cm dengan nilai K=0,000250, nilai BD paling besar diperoleh pada kedalaman 100 cm dengan nilai BD=0,377 gr/cm3, sedangkan nilai P terbesar diperoleh pada permukaan tanah kedalaman 0 cm dengan nilai P=81,074% dan untuk nilai WC terbesar diperoleh pada kedalaman 100 cm dengan nilai WC=224,324%. Dari beberapa karakteristik tanah gambut tropis, pada penggunaan lahan untuk perkebunan sawit, dapat dilihat hubungan antar parameter yang diamati berupa konduktivitas hidrolik arah horizontal dipengaruhi oleh bulk density, porositas dan water content, hal ini ditunjukkan dengan nilai R2 lebih besar atau sama dengan 0.94

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.

Abstract

Central Kalimantan has an area with a beautiful distribution of watersheds and abundant river products. Palangka Raya City is one of the watersheds included in it. Palangka Raya City has two rivers as estuaries for primary drainage channels, namely the Kahayan River and the Sebangau River. The Kahayan River is the final estuary of the primary drainage channels in the city of Palangka Raya, one of which is the IV primary drainage channel. This IV primary drainage channel is one of the primary drainage channels which contaminates the Kahayan River, which is its estuary. Contamination of contaminants from the primary drainage channel comes from domestic waste from residential communities living in the area. It is estimated that these pollutant materials will contaminate the water of the Kahayan River; thus, the need for research. In this study, the flow velocity and water level at a certain channel cross section were measured, then the water discharge was calculated, and several water samples taken from the middle of the IV primary drainage channel were tested for several parameters, namely BOD, COD, TSS, Ammonia, Oil-fat and Detergent. The results of the study showed that several test parameters had passed the predetermined class quality standard thresholds including BOD, Ammonia and Detergent so that they contributed to contaminating the Kahayan River. There are several parameters with a significant correlation between fluctuations in the water level and the value of the water discharge as indicated by the R-Square value > 0.67

Abstract

This study aims to analyze the pattern of groundwater flow around drains on tropical peatlands and to determine the effect of groundwater around drains on tropical peatlands with agricultural land functions. The research data used is primary data, namely water level, distance of each well pipe, coordinate points. In carrying out the analysis process using surfer software.The results showed that the pattern of groundwater flow around the drainage canal on tropical peatlands is that it tends to flow from the land to the drainage canal with the condition that the water level in the channel is lower than the groundwater level on the land.Besides that, from the results of the analysis carried out, it was found that the water level in the drain has an effect on the pattern of groundwater flow in tropical peatlands (agricultural land functions). The greater the difference in the height of the water level in the drainage canal (low water level condition), with the ground water level in the field (high water level condition), the pattern of groundwater flow tends to move towards the canal. However, when the water level in the channel is almost the same as the groundwater level in the field, the pattern of groundwater flow will change.
