Abstract

This study aims to analyze the effect of using rock dust as a partial replacement of fine aggregate on the compressive strength of concrete. The substitution variations used were 0%, 30%, and 75% of sand with a concrete design quality of fc' 25 MPa and the mixture planning method refers to SNI 7656:2012. Tests conducted included material characteristics, slump, setting time, and concrete compressive strength at the ages of 7, 14, and 28 days. The results showed that increasing the rock dust content affected the properties of fresh and hardened concrete. The highest slump value was obtained at the 30% variation of 170 mm, while the fastest setting time occurred at the 75% variation of 163 minutes. The results of the compressive strength test showed that normal concrete (0%) had the highest compressive strength of 26.16 MPa at the age of 28 days, followed by the 30% variation of 25.38 MPa, and the 75% variation of 20.37 MPa. Overall, 30% coal dust substitution still produces compressive strength close to normal concrete, while 75% substitution causes a significant decrease in compressive strength.

Abstract

Lifting is a common activity in fabrication and construction processes. It is a hazardous activity; failure during the lifting process can cause permanent damage to the products or structures being worked on. Furthermore, failure during the lifting process can endanger worker safety and even jeopardize the entire project. Lifting operations require not only calculations of the lifting equipment’s capacity—such as cranes and supporting tools like slings and shackles—but also an assessment of structural strength. Therefore, structural analysis under lifting conditions is essential; errors in planning can have severe consequences for the project. The planning stages are carried out using STAADpro software, starting from geometric modeling through to inputting parameters in accordance with applicable standards and regulations, such as the load magnification factor specified in DNVGL-ST -N001 Marine Operations and Marine Warranty, and the results of the analysis using STAADpro are re-verified through manual calculations in accordance with SNI 1729-2020 Specifications for Structural Steel Buildings. This verification process is carried out to ensure that the numerical analysis results obtained meet the requirements for strength, stability, and structural performance in accordance with design standards.

Abstract

Perhitungan volume dan berat tulangan balok beton bertulang secara manual rentan terhadap kesalahan akibat keterbatasan visualisasi dua dimensi, terutama pada bangunan dengan variasi tipe balok yang kompleks. Penelitian ini bertujuan membandingkan hasil perhitungan berat tulangan balok antara metode manual dan metode Building Information Modeling menggunakan Tekla Structures pada proyek Wijaya Guest House, bangunan tiga lantai dengan dak atap di Jakarta. Metode yang digunakan adalah kuantitatif komparatif, dengan data primer berupa hasil pemodelan tiga dimensi pada Tekla Structures dan data sekunder berupa gambar kerja serta Bar Bending Schedule dari kontraktor pelaksana. Perhitungan manual mengelompokkan balok ke dalam sembilan hingga sebelas tipe per lantai berdasarkan asumsi bentang bersih seragam, sedangkan Tekla Structures menghasilkan data quantity take off otomatis untuk dua puluh satu hingga tiga puluh dua cast unit individual per lantai sesuai geometri aktual di lapangan. Hasil penelitian menunjukkan total berat tulangan balok hasil perhitungan manual mencapai 21.248,10 kilogram, sedangkan hasil pemodelan Tekla Structures menghasilkan 14.948,50 kilogram, dengan selisih rata-rata 29,65 persen lebih rendah pada data aktual dibandingkan perhitungan manual. Selisih terbesar terjadi pada Lantai 2 sebesar 37,35 persen dan terkecil pada Dak Atap sebesar 11,53 persen. Analisis lanjutan terhadap estimasi Rencana Anggaran Biaya menunjukkan bahwa penggunaan hasil perhitungan manual berpotensi menyebabkan kelebihan anggaran pengadaan besi tulangan hingga 42,14 persen dibandingkan kebutuhan aktual. Penelitian ini menyimpulkan bahwa pemodelan BIM berbasis Tekla Structures memberikan estimasi volume dan berat tulangan yang lebih presisi, efisien, dan andal sebagai dasar pengendalian biaya proyek dibandingkan metode konvensional.
