Abstract

The rapid development of information technology, especially in the construction sector, has become an important issue in supporting the country's infrastructure needs to produce increasingly high-quality, integrated, and efficient infrastructure products. Therefore, the utilization of Building Information Modeling (BIM) technology has become an alternative that allows construction stages to be faster and more efficient, especially in minimizing waste material. This research aims to determine the influence of applying BIM concepts in optimizing waste materials for column reinforcement of type 1, type 2, and type 3. The research begins with data collection, structural 3D modeling, reinforcement modeling, input of reinforcement mark schedules, clash detection, Bar Bending Schedule (BBS) output, cutting lists, and waste material analysis. The research results show that the total weight requirement of type 1 column reinforcement is 28,449 kg, type 2 column is 26,390 kg, and type 3 column is 26,784 kg, while the total waste weight of type 1 column is 1,256.41 kg, type 2 is 872.6 kg, and type 3 is 916.14 kg. The waste level of type 1 column reinforcement is 4.42%, type 2 column is 3.31%, and type 3 column is 3.42%. Thus, it can be concluded that type 2 column reinforcement is more effective and efficient compared to type 1 and 3 column reinforcement.

Abstract

Abstrak Hasil dari pembakaran limbah kelapa sawit menghasilkan abu ketel yang dapat dimanfaatkan sebagai bahan pozzolan. Limbah genteng juga dimanfaatkan sebagai substitusi dari agregat kasar. Pembuatan benda uji kubus 15cm x 15cm x 15cm untuk diuji kuat tekan pada umur 3, 7, 14, dan 28 hari, dengan variasi pada bahan penyusunnya 5% abu ketel terhadap berat semen dan 5%, 10%, 15%, dan 20% limbah genteng terhadap berat agregat kasar. Kuat tekan terbesar pada umur 28 hari untuk beton dengan substitusi hanya limbah genteng terdapat pada variasi 5% (G5) dengan kuat tekan 34,86 MPa. Substitusi 5% abu ketel untuk semen pada G5, kuat tekan beton mengalami peningkatan yang cukup signifikan menjadi 37,45 MPa. Hasil kuat tekan pada benda uji dengan kadar limbah genteng lain seluruhnya mengalami peningkatan kuat tekan setelah dilakukan substitusi 5% abu ketel pada semen. Sehingga subtitusi 5% abu ketel dapat meningkatkan kuat tekan pada beton dengan substitusi limbah genteng. Kata kunci: Abu ketel, limbah genteng, kuat tekan Abstract The combustion of palm oil waste produces boiler ash, which can be used as pozzolanic material. Tile waste is also used as a substitute for coarse aggregate. A 15cm x 15cm x 15cm cube specimen was produced to test the compressive strength at 3, 7, 14 and 28 days with variations in the constituents 5% boiler ash by weight of cement and 5%, 10%, 15% and 20% tile waste by weight of coarse aggregate. The highest compressive strength at 28 days for concrete with only tile waste substitution found in the 5% variation (G5) with a compressive strength of 34.86 MPa. Substituting 5% boiler ash for cement in G5, the compressive strength increased to 37,45 MPa. The compressive strength of other variations of tile waste increased after 5% substitution of boiler ash in cement. Therefore, 5% boiler ash substitution can increase the compressive strength of concrete with tile waste substitution. Keywords: boiler ash, tile waste, compressive strength
