Abstract

The development of Project X Cibubur is located on Alternatif Cibubur Street, West Java. The project, which is built on a land area of ± 40100 m2, is a superblock in one area where there are malls, hotels, and apartments. The purpose of this research is to analyze and calculate the concrete demand for column work in Project X Cibubur. The type or form of column used in this project is square with several types of columns. The method of implementation carried out in column work includes preparation, measurement of axles, fabrication of reinforcement and formwork, transportation, installation, inspection, casting, dismantling formwork and maintenance. After calculating the volume of concrete requirements for column work, the total volume of concrete requirements for type K3A is 76.649 m3, K4A is 50.808 m3, K4B is 3.368 m3, and K4C is 3.334 m3. The total volume of concrete demand in column work is 134,159 m3.

Abstract

The current technology for using recycled materials in road preservation work is very helpful in maintaining the sustainability of the materials used. Waste from road materials that will be repaired can be reused for new foundation layers. The aim of this research is to obtain a design for the percentage of cement, percentage of emulsified asphalt, unconfined compressive strength and optimum water content in accordance with the applicable engineering specifications so that it can be proven that the existing material from the top foundation layer and asphalt layer can still be used as a new foundation layer. The research method involves conducting experiments on existing materials by conducting laboratory tests on samples of top foundation layer aggregate and existing asphalt in the Cikarang Industrial Area. The experiment was carried out at the Jakarta State Polytechnic Civil Engineering Laboratory with 9 test samples. The results obtained for the recycled foundation layer were that the design cement required was 30.8 grams and 53.1 grams of emulsified asphalt for an area of ​​1m2 with a 7 day unconfined compressive strength obtained from nine samples for variations in cement content of 1%, 3%, and 5% maximum 2.81MPa, so the optimum cement content is 3.6%.
