Vehicle mobilization will experience less obstacles if the road pavement conditions are in good quality. At the moment, additives, fillers or road material substitutes are quite expensive and are limited, therefore, research needs to be carried out to find materials which can improve the quality of pavement such as increasing its resistance or stability and flow. The purpose of this study was to analyze the benefits of using wall fragments as the fillers in asphalt concrete wearing course. The effect of using wall fragments as a substitute for rock ash on the value of Marshall parameters is studied, as well as the various levels of wall fragments addition that can produce the greatest stability. In this study, four levels of wall fragments were used as fillers: 0%, 25%, 50% and 100%. Based on the results analysis, it was concluded that the use of wall fragments as fillers in asphalt concrete can increase the following parameters: VMA, VIM, stability, and flow, but it reduces the VFB value. In addition, the use of 25% levels of wall fragments in asphalt concrete produces the greatest stability value, which is 1622.47 kg.","PeriodicalId":338977,"journal":{"name":"Cantilever: Jurnal Penelitian dan Kajian Bidang Teknik Sipil","volume":"226 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132023175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it needs an improvement effort to increase the strength of the clay soil. The reinforcement soil column is an alternative effort to improve the soil. This paper presents the results of laboratory-scale experimental on the reinforcement modelling of clay soil columns mixed with 6% rice husk ash (RHA). Modelling was carried out with 6 variations of column groups with constant column length of 67cm. The first three variations are the variation in the distance between columns (s/d) with a fixed diameter of 8 cm. The other three variations are column diameter variations with a fixed s/d ratio. The results showed that the larger the distance between the columns, the smaller the bearing capacity of the soil foundation. If the s/d ratio is constant, it is found that the larger the column diameter, the greater the bearing capacity of the soil foundation. The maximum ultimate bearing capacity of the soil is achieved in variations with a column diameter of 12cm and a distance between columns of 30cm (s/d = 2.5) with a value of 39.56 kPa. This bearing capacity provides a BCR value of 3.75% or almost 4 times the bearing capacity of the unreinforced foundation.","PeriodicalId":338977,"journal":{"name":"Cantilever: Jurnal Penelitian dan Kajian Bidang Teknik Sipil","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116642403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such conditions, the choice that is often taken is to move the river flow. Displacement of river flows in accordance with the regulations allowed has its own challenges to minimize the risks that will occur to the environment. The aim of the study is to design the basis of a new channel to reduce the speed of the river flow, so that the function and sustainability of river use as an ecological function is not disturbed. The method used is to analyze the origin of the river channel discharge and design the dimensions of the diversion river channel. The results obtained, with forecasts of a 50 year return peak flood period of 104.17 m3 / sec and with a divergence in the elevation of the diverting river channel of 18.9 m between the planned upstream and downstream along the 6,212.7 m, then to avoid massive scouring at channel base, a maximum flow rate of 10 m / sec and a minimum of 0.8 m / sec with a channel bottom of 0.0005% is recommended. For this reason the base profile of the canal is trapped at a distance of 500 m, with an elevation difference of 0.25 m. To maintain ecological sustainability, the dimension of the diversion river channel is maintained the same as the original river, b = 8m, H = 3.5m, and H : V = 1.5: 1.","PeriodicalId":338977,"journal":{"name":"Cantilever: Jurnal Penelitian dan Kajian Bidang Teknik Sipil","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132157075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to examine the GIS processing function embedded in the latest HEC-HMS software version 4.4 for the delineation of watershed and elements of the hydrological model. In comparison, watershed delineation was also carried out by using ArcGIS software. The area of study is the Bendung subbasin located in Palembang City, where terrain data used is a National DEM data with a spatial resolution of 8 m (0.27 arc-second). The results showed that the boundaries and area of the watershed produced by HEC-HMS 4.4 and ArcGIS showed the same characteristics. The river network produced by the two software shows a slight difference even though the flow patterns are similar. It shows that the level of accuracy and quality of the delineation produced by the HEC-HMS 4.4 is excellent. Besides, elements of the hydrological model can be generated automatically which is not found in previous versions. It allows users to more quickly simulate detailed hydrological models with a large number of elements. Therefore, the use of GIS functions in HEC-HMS 4.4 must be encouraged for various analysis purposes in water resources projects.","PeriodicalId":338977,"journal":{"name":"Cantilever: Jurnal Penelitian dan Kajian Bidang Teknik Sipil","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129862075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For successful implementation, it is necessary to identify potential areas for RWH implementation. This study aims to identify areas in Palembang that are potential for implementing the RWH system. An analysis of parameters that affect the classification also conducted. This study used a geographic information system (GIS) approach using rainfall, slope, land use, and soil type parameters which are structured in a hierarchy using the analytical hierarchy process (AHP). Based on the weighted overlay method, it can be concluded that a very potential area for RWH implementation dominated with a wet area, flat slope, dense residential area and the type of soil which is not susceptible to infiltration. Whereas the medium and non-potential areas are dominated by steep and very steep slopes as well as unoccupied land use. Areas of high potential and potential reach 18.17% and 66.14% respectively. While the medium and not the potential is 13.66% and 2.03%. Areas of great potential are in the Buah, Kidul, Sekanak, Sriguna, Bendung, and Selinca Sub Watershed. Non-potential areas are only available in small area in DAS Gandus, Gasing, and Lambidaro Sub Watershed.","PeriodicalId":338977,"journal":{"name":"Cantilever: Jurnal Penelitian dan Kajian Bidang Teknik Sipil","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128280236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
