Abstract
masih menggunakan metode konvensional. Proses bongkar pasang begesting kolom akan menunda waktu pemasangan batu-bata, sehingga dalam menyelesaikan bangunan akan membutuhkan waktu yang semakin lama. Menggunakan komponen prapabrikasi merupakan salah satu solusi untuk mempersingkat waktu dalam pengerjaan bangunan. Tujuan penelitian ini adalah untuk mengkaji (1) persentase limbah kaca sebagai pengganti sebagian agregat halus agar diperoleh nilai penyerapan air segmen kolom modular yang minimal; (2) persentase optimal limbah kaca sebagai pengganti sebagian agregat halus agar diperoleh kuat aksial kolom modular beton yang maksimal; (3) perbandingan kuat aksial dan biaya pembuatan kolom praktis konvensional dengan kolom modular beton. Penelitian kuantitatif ini menguji uji penyerapan air segmen kolom modular yang mengacu SNI 03-0349-1989 dan uji kuat aksial kolom modular beton yang mengacu SNI 2847-2013. Biaya pembuatan dan pekerjaan benda uji menggunakan acuan Keputusan Walikota Surakarta Nomor 050-151 tahun 2019 Tentang Standar Satuan Harga tahun Anggaran 2019 dan Peraturan PUPR 28/PRT/M/2016 tentang Analisis Harga Satuan Pekerjaan Bidang Pekerjaan Umum.
