Abstract

The Industry revolution 4.0 has become a prominent topic of discussion, emphasizing the need to harness digital technology to enhance various aspects of human work, including the construction industry. In the field of construction, Building Information Modeling (BIM) has been widely adopted as a guiding framework for construction processes. Additionally, Augmented Reality (AR) technology has emerged as a powerful tool for bringing 3D models into the physical world. This research employs a qualitative approach, utilizing 3D design data of Pile Caps in the construction of the IKN Minister's Residence and Solo - Yogyakarta Toll Road Office. A total of 74 and 68 coordinate points were extracted from each design to analyze the discrepancies resulting from the implementation of AR technology. The findings reveal that both designs exhibited a margin of error of 0.6148648649 % for the IKN Minister's Residence and 0.6102941177 % for the Solo - Yogyakarta Toll Road Office, both of which fall below the 1% threshold for maximum allowable error.

Abstract

Produksi semen merupakan suatu proses energi yang intensif dimana menghabiskan sejumlah besar energi, serta pembuatan semen meyumbang emisi CO2 sekitar 7% ke atmosfir. Sekam padi bila dibakar dengan suhu tertentu menghasilkan silika amorf yang bersifat reaktif sehingga potensial digunakan sebagai bahan mikrosilika. Penelitian ini bertujuan untuk menganalisis nilai kuat tekan mortar geopolimer yang menggunakan abu sekam padi dan limbah plastik PET (Polyethylene Terephthalate) sebagai material yang ramah terhadap lingkungan. Penelitian ini berbentuk uji eksperimental di laboratorium. Mortar geopolimer diproduksi dengan menggunakan fly ash, abu sekam padi sebesar 5% dari berat fly ash dan limbah plastik PET sebesar 0,25%, 0,50%, 0,75% dan 1,00% dari berat agregat halus. Pengujian kuat tekan dilakukan pada umur 7 dan 28 hari. Hasil penelitian menunjukkan bahwa nilai kuat tekan meningkat seiring dengan penambahan plastik PET 0,25% dan mengalami penurunan dengan penambahan plastik PET hingga 1,00%. Hasil penelitian ini dapat digunakan mendukung penggunaan konstruksi dengan pemanfaatan material-material limbah atau buangan yang pada akhirnya dapat mendukung pembangunan infrastruktur nasional berbasis material limbah (green construction).
