Abstract

Research in the site of construction is currently focused on utilization of unique, innovative, and cost-effective construction materials for long-term purposes, particulary in the context of green buildings. One material that has gained attention is tralucent concrete or light-transmitting concrete, which employs nano-optic concepts and fiber optic to transmit external light through its internal spaces. This study present a comprehensive review of previous research on light-transmitting concrete, specifically examining its applications, optimalization fiber ratios, and arrangement. Furthermore, the investigation delves into the propertiesencompassing liht transmission, mechanical strength, and energy efficiency of transparent concrete. To maximize light transmission, various proportion of fiber optic, count 3%, 4%, and 5% were incorporated into the concrete mixture. As aresult, this study aims to identify differet types of transparent materials, elucidate their properties and offer pratical illustration and application to addres these research gaps. Indeed, this research contributes to advancement of innovative construction materials, which have potential to enhance energy efficiency .

Abstract

Building structure planning has an important role for further consideration before the implementation of construction in the field to anticipate construction failure, so it requires knowledge based on applicable rules and strengthened with software to support construction success. The structural planning research on the re-design of the UNESA Sports Psychology Integrated Building project using SAP2000, aims to provide knowledge in applying the concept of building structure design and has an output in the form of structural dimensions and reinforcement in accordance with the rules of PPIUG 1983, SNI 1726-2019, SNI 1727-2020, SNI 2847-2019, and RSA Ciptakarya. The method used is planning the dimensions of the upper structure, analyzing the working load, analyzing the structure using SAP2000, and planning the lower structure with a strong bearing capacity to accept the vertical load of the structure from the SAP2000 analysis results. Based on the final results obtained for the floor slab has two types S1 (12 cm thick, Ø10- 150), S2 (10 cm thick, Ø10-150), Tiebeam and beams with types TB1 (40/75 cm 6D22), B1 (50/70 cm 13D22), B1a (50/70 cm 11D22), B2 (40/60 cm 9D19), B3 (30/50 cm 9D19), B4 (30/40 cm 8D19), Columns of type K1 (80/80 cm 22D22), K1a (80/80 cm 24D22), K1b (80/80 cm 20D22), K1c (80/80 cm 18D22), K2 (70/70 cm 18D22), K3 (68/68 cm 16D22), K4 (60/60 cm 16D19), KL (43/43 cm 10D19), and foundations with a spoonpile diameter of 60 cm number 4 with pilecap dimensions (350/350 cm D16-150).

Abstract

The increase in development has increased the need for construction materials. One material often used is red bricks as a wall pair or barrier in the house. On the other hand, red bricks also have added value in terms of aesthetics. Generally, the main ingredients of bricks are clay, rice husks, and water, which are molded in a square shape, and the hardening process is through burning until it turns red and hard. By looking at the high need for bricks, this research aims to make a mixture innovation to the composition of bricks, namely adding gypsum powder waste to the composition of clay and bamboo leaf ash to the composition of rice husks. The variation used in this innovation is 2.5% gypsum powder waste in each sample of mixed red bricks, then in the variation of bamboo leaf ash by 5% and 7.5%. Like conventional red bricks, the size of red bricks is 23cm long, 10cm wide, and 5cm thick. The test results on conventional red bricks have a compressive strength value of 1.27 MPa and water absorption of 11%, while in red brick innovation, the optimal compressive strength value is in the variation of 2.5% gypsum powder waste in clay and 5% bamboo leaf ash in rice husk has a compressive strength value of 1.58 Mpa and water absorption of 9% where mixed red bricks are superior to conventional red bricks.

Abstract

Building Information Modeling (BIM) is a method of processing data during the life cycle of a construction project that uses three-dimensional, real-time, and dynamic building modeling software, thereby creating a complete model related to project data from the planning to the construction phase of the project. In the re-planning of the Yogyakarta Nuclear Science and Technology (KST) Dormitory Building based on Building Information Modeling (BIM) 5D, a special moment resisting frame system (SRPMK) structure was used. The planned building consists of 7 floors, including the lower structure consisting of a 50x50 square pile foundation and five types of pile cap, the upper structure consisting of columns, beams, and floor plates. The quality of concrete in the structure used is fc' 40 Mpa and 35 Mpa with reinforcing steel quality fy 420B. In this planning, 2D and 3D modeling was carried out. Structural analysis was carried out using the SAP2000 application, which was then continued with 2D 3D modeling and Quantity take-off results using Revit and Scheduling using Ms. Projects. The Draft Budget (RAB) results for this planning are Rp. 37,691,368,000.00. The planned duration of work is 26 weeks. The results of the scheduling and RAB are then integrated using the Naviswork software so that the simulation results of the work to be planned can be seen.
