Abstract

Palangka Raya is a city where almost a part of the area is peatland with peat water with an acidity level of around 4.0 - 5.0 which can make concrete become porous and cause damage. This study is to determine the effect of peat water, Kahayan river water, and PDAM water on the compressive strength of concrete. In this study, the immersion of concrete samples was carried out for 28 days and 60 days. The measurement results are known that the pH of peat water is 4.0 while the pH of Kahayan river water and PDAM water is 5.0.From the results note that in the 28 days immersion, peat water concrete has increased in compressive strength while concrete in Kahayan river water and PDAM water has decreased in compressive strength. However, during the 60 days immersion the peat water concrete decreased in compressive strength to 20,638 MPa (17.31%). Whereas the Kahayan river water and PDAM water in the 60 days immersion experienced an increase in compressive strength values of 31,687 MPa (26.96%) and 27,696 MPa (10.98%). From these results, it can be concluded that the Kahayan river water with pH = 5.0 does not make the concrete lose its strength and can survive in an acidic environment.

Abstract

Peatlands rewetting for hydrological restoration plays an important role in fire prevention and peatland restoration of degraded peatland. One of the methods for the rewetting is canal blocking. The impact of canal blocking for peatland rewetting is further analyzed in this research. This study focused in Pulau Tebing Tinggi peatland hydrological unit (PHU), which is located in Kepulauan Meranti Regency, Riau Province. To analysis the rewetting impact, 15 dipwells were installed with the distance of 1 m, 51 m, 101 m, 201 and 301 m from the canal for each transect of the three transects. A transect was set in the downstream and two transects were set in the upstream of canal block. The ground water level (GWL) in the 15 dipwells was recorded using water-loggers for one year. This research found that canal blocking has a good effect on maintaining groundwater levels and keeping peatlands in always wet or humid conditions up to a distance of 201 m perpendicular to the canal if the rise in water level in the canal due to canal blocking is more than 0.6 m. It is able to maintain the ground water depth in peatlands around 0.4 m, where the peatlands become low risk to the fire, emission rates and subsidence.

Abstract

This paper presents an experimental study on the behaviour of a braced steel frame with a proposed system: anticompression brace system (ABS) subjected to cyclic lateral loads. The ABS is proposed to deal with common brace buckling problems. In the study, split-K braced steel frames: with ABS and with ordinary brace system (OBS) were used as speciments. Cyclic loading tests were conducted to evaluate the performance of the proposed system in preventing the brace to buckle and to obtain the behaviour of the frame with ABS compared to the frame with OBS under cyclic quasistatic loading. From the cyclic tests, it was observed that the proposed system worked in preventing the braces to buckle, hence, the aimed state, “buckling prevention” was achieved. The results of the study also show that the frame with ABS had a lower initial stiffness compared to the frame with OBS, nevertheless, after exceeding drift ratio of 0.85% based on raw data or 0.64% based on fitted-curves, the frame with ABS exhibited good behaviour through lower degradations in stiffness and cyclic strength relative to the frame with OBS that experienced sudden and greater degradations.

Abstract

Flyover and underpass are an important part of the road network system, especially to reduce congestion. These flyover and underpass construction projects have unique and very complex characteristics, so they face various types of risks that may occur during the project life cycle. Risks that occur can affect the cost, time and quality of construction projects, which in some cases can even have a serious impact on the sustainability of the project itself. Risk may occur due to several risk factors that cause it. Since the construction of flyover and underpass is very important and is a very strategic and usually large-scale project, a study of the types of risk factors that might occur during the construction of flyovers and underpass in Indonesia is needed. This research is dedicated to answering this problem. This study uses the literature review method for data collection. Based on the results of the study it was found that the risk of the conception stage is an obstacle in land acquisition, the planning stage is a change in design, the implementation stage is safety and safety.

Abstract

The limitations of spatial and temporal distribution of rain gauge networks causes inaccuracies in prediction of hydrological modeling. The availability of satellite rain data products is a potential to overcome this limitation. This studies objective is to compare the quality of rain data from the recording of the Manual Rainfall Recorder (MRR) with satellite data TRMM 3B42 which is entered in the HBV hydrological modeling. Calibration results shows that HBV modeling performance with MRR rain data input is better than TRMM. R2 and NSE values from MRR rain data input were 0.7153 and 0.7133 respectively with a mean error of 89 (mm / year). While the R2 and NSE values of the TRMM 3B42 satellite rain data input were 0.57 and 0.55 with a mean error of 305 (mm / year), respectively.
