ABSTRACT The development of the palm oil industry which continues to increase has an impact on palm oil waste in the form of ash from burning palm shells, known as POFA (Palm Oil Fuel Ash). One way to reduce the number of POFA is to use it in the field of Civil Engineering. In this study, Palm Oil Fuel Ash (POFA) was used as a material for the embankment in road pavement construction. In addition to using POFA, this study also used additional materials in the form of cement with the percentage addition of 2%, 4%, 6% and 12%. The results of the soaked CBR and UCS tests in the laboratory showed that the CBR and UCS values increased with increasing cement content in each variation. The value of CBR and UCS increased and reached the maximum value at the addition of 12% concentration, which was 28.01% for CBR and 4.903 kg/cm2 for UCS. The value obtained has reach the standard and can be used as a choice of embankment material.","PeriodicalId":231649,"journal":{"name":"Fondasi : Jurnal Teknik Sipil","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125722135","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}

The use of natural aggregates as materials for road infrastructure reduces availability, necessitating the need for alternative materials, one of which is nickel slag. The increase in nickel production is directly proportional to the increase in nickel slag production as a byproduct of nickel processing. The purpose of this research was to assess and control the performance of asphalt mixtures containing nickel slag in the Intermediate Laston (AC-BC) pavement layer. The physical properties of the materials used, namely asphalt, aggregate, and nickel slag, were tested, and for the chemical and mineral properties of nickel slag, X-ray fluorescence spectrometry (XRF), X-ray diffraction (XRD), and Scanning Electron Microscope well as the results of testing the physical properties of nickel slag meet the requirements used in road construction materials. As a result, nickel slag is a viable alternative for environmentally friendly road construction materials.","PeriodicalId":231649,"journal":{"name":"Fondasi : Jurnal Teknik Sipil","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131159879","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}

One type of research in an effort to improve the weakness of concrete is by adding fiber which is expected to increase the tensile strength of the concrete. In this study, the fiber used is bamboo fiber. To ensure uniformity in the shape and size of the fibers, bamboo fibers that have been processed in the form of toothpicks are used. The toothpicks used are 1.5 mm in diameter and 25mm long. This study uses several percentages of fiber, namely 0.5%; 1.0%; 1.5% and 2.0% by volume of concrete. The test carried out is the slump test, compressive strength and split tensile strength The compressive strength and split tensile strength tests were tested when the concrete was 28 days old. The results of this study indicate that the concrete reaches a maximum compressive strength at a fiber percentage of 1.0% of 34.90 MPa with an increase of 31.20% from normal concrete and the split tensile strength value reaches a maximum value at a percentage of 0.5% fiber of 4, 01 MPa with an increase of 22.76% than normal concrete.

The analysis used the USLE model to predict sedimentation rates due to land erosion that occurred in the rain catchment area upstream of Jurug dew. Estimating the sedimentation rate in jurug dew aims to prepare the next step as a form of handling the impact of sedimentation that occurs. The results of the analysis showed that the average amount of erosion that occurred in the watershed upstream of Embung D.I.
