Abstract

Technological developments in the construction world are also growing along with technology development. The application of BIM (Building Information Modeling) is one of the technological developments that can simplify the construction process, optimize time and human resources, and collaboration between stakeholders. Kalibanger Bridge is one of the bridges that crosses the Kalibanger River, connecting Semarang City and Demak Regency. The Kalibanger Bridge Replacement Project has been carried out from September 2022 to October 2023. Based on BIM, the re-planning of Kalibanger Bridge, Semarang City, was done by re-planning, modeling, and project scheduling. The methods presented are data collection, data analysis and structural analysis, 3D modeling using Tekla Structures, preparation of RAB, and scheduling. The re-planning of Kalibanger Bridge with BIM integration is expected to increase the ease and accuracy of the quantity take-off process and facilitate the scheduling process.

Abstract

In Indonesia, concrete roof tiles are still relatively expensive. This can be seen from the composition of the mixture and the concrete tile production process. Based on cost considerations, the alternative is to use glass powder waste and quenched lime. Lime as an alternative choice because the chemical elements contained are almost the same as cement. Glass powder waste contains silica which is expected to increase the density of concrete roof tiles. Therefore, this research was conducted with the aim to see the effect of adding glass powder waste and slaked lime to the values of flexural load, absorption, and water seepage. The method used is the experimental method, with a mixture of cement and sand composition, namely 1: 3 and using 4 variations of the test object, namely for quenched lime with variation A 0%; B 10%; C 0%; D is 10% by weight of cement while for variations of glass powder A is 0%; B 0%; C 10%; D 10% by weight of sand. This test includes appearance, size, value of bending load, absorption, and water seepage. The result of average bending load in variations A = 1548,51 N, B = 1562,25 N, C = 1675,57 N, D = 1751,43 N. For the result of average water absorption in variations A = 9,248%, B = 6,675%, C = 9,512%, D = 7,093%. The use of glass powder waste and extinguished lime can increase the value of bending load, absorption and water seepage compared to ordinary concrete roof tiles. So as to produce concrete roof tiles that are economical and also reduce waste but still meet the quality according to SNI.

Abstract

Along with the times in the Industrial Revolution 4.0, innovation in the construction field is needed to achieve a specific innovative idea. One is making red bricks using a mixture of ash, sawdust, and glass powder. For the composition used in red bricks with a mixture of ash, sawdust, and glass powder amounting to 0%, and 2.5% and 0%, 2.5%, 5%, and 7.5% of the weight of the bricks used, based on these percentages, it can also reduce the price of production materials. The researchers did the test method by testing the brick's compressive strength and the absorbency of water. This aims to find out how significant the influence of the mixture of ash, sawdust, and glass powder is on the quality of the brick's compressive strength and the level of water absorption in the brick. It is hoped that the research of red bricks using a mixture of ash, sawdust, and glass powder is expected to be an alternative solution for the utilization of red brick mixture materials to reduce the cost efficiency of production materials and to determine the quality results of brick compressive strength and water responsiveness to bricks based on the test method to be carried out.
