Abstract

The road surface is often suffered from crack caused by high shrinkage property of clay as base soil. One of several methods to overcome this is by stabilizing it by adding Portland Pozzolan Cement (PPC) and dolomite in the clay. The method used in this research is experiment based on trial and error method. Mixture percentage used is 0%, 5%, 10%, 15% dan 20 % from total mixture weight, with hardening time 0 day, 7 days, 14 days, 21 days and 28 days. The results show that the more PPC mixture and dolomite percentage, the stronger the soil support strength (CBR value). The best result from this research is the mixture of clay, PPC and dolomite at 20% with hardening time of 28 days and CBR = 52,2757% (increases 1088,4211%).

Abstract

The imbalance between the number of vehicles parking and parking off-street parking generation resulted automatically take advantage of the road for parking. From the analysis of the capacity of roads in Mega Town Square on segment Jl. Yos Sudarso, it is known that the level of service is still in accordance with Decree No. KM 14 of 2006, AASHTO, 1973 and Morlok, 1990. On Saturday morning the street value of the service is stable at current low traffic density with a rather high speed but can be controlled by the driver based on the speed limit maximum/minimum and the physical condition of the road. On Saturday afternoon, the traffic density was at a pace that can be controlled by the driver with the value of the service road approaching unstable flow speed of 25 Km/hour. On Saturday night, the traffic density is high enough to speed decreases, and can not be controlled by the driver currents sehinnga restrained. Total vehicle parking per hour is 60 veh/hour. This value is adjusted to supply vehicles going out into the market as much as 100 veh/h. So that parking availability is still sufficient to accommodate the vehicles in the Mega Town Square.

Abstract

Along with the level of traffic density that crosses the Pinus road, there are several obstacles that cause damage, one of which is the damage that occurs in the road construction section, which is caused by the load of vehicles with excessive loads such as trucks, which further causes damage to the road, namely an increase in volume. heavy traffic every day. Asphalt pavement is generally used on roads that have a fairly dense traffic volume, with the increase in the number of vehicles resulting in damage in a relatively short time than planned. The purpose of this study is to determine the effect of the volume of vehicle types on road damage on asphalt pavement, it can be predicted earlier the value of road damage that will occur, the method used in this study is the method of analyzing vehicle volume on road damage with the regression method. Used to obtain the relationship function with the value of R² (coefficient of determination) which shows the magnitude of the effect of changes in the volume of vehicle types on changes in the value of road damage, this study was carried out on the Pinus road, Palangka Raya City. There is a relationship between the volume of vehicle types and the value of road damage, the results obtained are R² = 0.744 which shows that road damage is influenced by the volume of heavy vehicles, light vehicles and motorcycles with a percentage value of 74.4%. From the results of the equation between heavy vehicles (X1), light vehicles (X2), motorcycles (X3), and the value of road damage Y = 0.159 X1 + 0.034 X2 + 0.017 X3 + 14,189. From these equations it can be described as follows, the regression coefficient (X1) (a) = 0.159 means that a heavy vehicle of 100 vehicles/day will increase the level of road damage by 5.9, the regression coefficient (X2) (b) = 0.034 means a light vehicle of 100 vehicles/day will increase the level of road damage by 3.4, Regression coefficient (X3) (c) = 0.017 means that 100 motorbikes/day will increase the level of damage by 1.7, constant (c) = if there are no vehicles driving passing a road segment, the road will experience road damage of 14,189.

Abstract

Measuring air retention in constructed canal blockage is critical for determining changes in air content after canal blocking. The purpose of this study is to assess the influence of changes in levels on air retention values measured at three depths, namely 0-20 cm, 20-40 cm, and 40-60 cm, at four transect sampling stations created at a distance of 10 m to 260 m from the canal block. Changes in bulk density, porosity, and peat volume affect groundwater. Peat soil samples were collected from burned peatlands, and canal blocks were constructed. A pressure plate chamber was used to assess air retention. The findings of the investigation revealed that the air retention pattern of peat soil at 16 test sample locations was at maximum at PF 0.2 at each depth. At higher pressures (pF 2-4.2), peat groundwater is strongly bonded by peat soil particles. The average bulk density of peat is 0.2 2 and the porosity value is 86.79%. The higher the air content at each pF value has no influence on the porosity and bulk density values. Changes in air content between pF 2.0 and 4.2 lower average peat volume by 7.4%. The size of this value is assumed to be determined by the peat's type, maturity, and decomposition value.

Abstract

One of the elective courses in the Building Engineering Education Study Program, FKIP, Palangka Raya University is Bridge Structure. Experimental study is a way of teaching and learning that involves student activity by experiencing and proving for themselves the process and results of experiments which are closely related to everyday life. On the subject of bridge structures, it is necessary to carry out experimental studies on bridge pillars. Pillars are part of the bridge's lower structure. The existence of pillars in river flows causes changes in river flow patterns. Changes in flow patterns will result in local scouring around the pillars. This research aims to determine the effect of pillar shape on the potential for local scour that occurs around the pillar. This research was carried out under steady uniform flow conditions with three discharge variations. The physical models of pillars used are rectangular pillars, cylindrical pillars and triangular pillars. The type of research used is experimental research. The research location was carried out at the Building Engineering Education Laboratory, FKIP UPR with glass channel media with dimensions of 200 cm long, 15 cm wide and 20 cm high. In the test with flow discharge Q1= 40.08 cm3/sec, the maximum scour in the middle of the pillar that occurred was (ds)= 0.2 cm and the average at the edge was (ds)= 0.3 cm for pillars with the shape rectangular, while for triangular and cylindrical pillars experiencing sedimentation, Q2= 100.20 cm3/sec. The maximum scour at the center of the pillar that occurs is (ds)= 1.3 cm and the average at the edges is (ds) = 1.4 cm for rectangular pillars, while for triangular and cylindrical pillars experiencing sedimentation, Q3= 107.04 cm3/sec. The maximum scour in the center of the pillar that occurs is (ds)= 1.5 cm and is flat -average at the edge is (ds)= 1.5 cm for pillars with a rectangular shape, while for pillars with a rectangular shape and cylinders experience sedimentation. The results obtained from this series of research are that the greater the discharge flowing in a channel cross-section, the deeper the local scour around the pillars will be and the best shape in this study is a cylindrical shape because it has the potential for the smallest scour depth.

Abstract

Peatlands are an ecosystem that has an important role in the environment, including carbon storage, biodiversity habitat, and water availability (Murdiyarso et al., 2010). However, peatlands are also very vulnerable to fire, especially in extreme dry season conditions (Page et al., 2002). Peatland fires can cause significant environmental losses, including greenhouse gas emissions, loss of biodiversity, and negative impacts on public health due to the smoke produced (Masykur et al., 2019). Therefore, efforts to prevent peatland fires are very important to maintain the sustainability of this ecosystem and public health. The hydram pump method was chosen as an innovative solution in this research because of its ability to pump water continuously without requiring an electricity or fuel source. This makes it a sustainable and environmentally friendly alternative for wetting peatlands, which in turn can increase soil moisture and reduce the risk of fire (Wardhana et al., 2021). By utilizing this method, it is hoped that soil moisture can be maintained, making the land less susceptible to fire. The type of research used is experimental research. The research location was carried out at the Building Engineering Education Laboratory, FKIP UPR with a hydram pump and a drip irrigation system on differences in land elevation from plant water sources and water use efficiency. The target achieved is that this research will be published in the SINTA 5 and HKI Accredited Journals.
