Indonesia merupakan wilayah dengan aktivitas seismik tinggi sehingga bangunan perumahan memerlukan kinerja lateral yang memadai terhadap beban gempa. Penelitian ini mengevaluasi perilaku siklik portal beton bertulang skala penuh berdinding pengisi panel pracetak ferrofoam concrete yang merepresentasikan konfigurasi perumahan sederhana di Banda Aceh. Benda uji berukuran 3.250 mm × 3.280 mm, menggunakan kolom 130 mm × 130 mm, balok dan sloof 130 mm × 200 mm, serta panel pracetak ferrofoam concrete sebagai dinding pengisi. Pengujian dilakukan dengan pembebanan lateral siklik berbasis kontrol perpindahan untuk memperoleh kurva histeresis, kapasitas lateral, degradasi kekakuan, energi disipasi, Equivalent Viscous Damping Ratio (EVDR), daktilitas, dan pola kerusakan. Kapasitas maksimum mencapai 28,23 kN pada arah dorong pada perpindahan 107,15 mm dan 31,10 kN pada arah tarik pada perpindahan 107,35 mm. Kekakuan menurun dari 2,065 kN/mm menjadi 0,161 kN/mm pada perpindahan akhir sekitar 149,94 mm. Energi disipasi maksimum mencapai 1.419,840 kN·mm pada arah dorong dan 1.510,006 kN·mm pada arah tarik, sedangkan EVDR berada pada kisaran 5,96%–16,10%. Daktilitas eksperimental diperoleh sebesar 11,07 pada arah positif dan 10,15 pada arah negatif. Kerusakan berkembang bertahap dari retak pada panel, retak vertikal dan diagonal lokal, pemisahan panel-kolom, hingga kerusakan lokal pada sambungan portal. Kapasitas benda uji mencapai sekitar 3,73-4,11 kali kapasitas teoretis portal kosong sebesar 7,56 kN. Evaluasi terbatas terhadap SNI 9273:2025 melalui kurva selubung menghasilkan batas drift IO sebesar 0,19%, LS sebesar 0,82%, dan CP sebesar 1,05%. Meskipun telah melampaui batas CP, benda uji masih mempertahankan tahanan lateral hingga drift sekitar ±4,90%, yang mengindikasikan adanya cadangan kapasitas deformasi pascaleleh. Hasil penelitian menunjukkan bahwa panel pracetak ferrofoam concrete berpotensi dikembangkan sebagai alternatif dinding pengisi ringan pada portal beton bertulang perumahan sederhana di wilayah rawan gempa.

Indonesia is located in a highly active seismic region; therefore, residential buildings require adequate lateral performance under earthquake-induced loading. This study evaluates the cyclic behavior of a full-scale reinforced concrete frame infilled with precast ferrofoam concrete panels representing typical low-rise residential construction in Banda Aceh. The 3,250 mm × 3,280 mm specimen consisted of 130 mm × 130 mm columns, 130 mm × 200 mm beams and grade beams, and precast ferrofoam concrete infill panels. Displacement-controlled lateral cyclic loading was applied to obtain the hysteretic response, peak lateral strength, stiffness degradation, dissipated energy, Equivalent Viscous Damping Ratio (EVDR), ductility, and damage pattern. The maximum lateral strength reached 28.23 kN in the push direction at a displacement of 107.15 mm and 31.10 kN in the pull direction at a displacement of 107.35 mm. The stiffness decreased from 2.065 kN/mm to 0.161 kN/mm at a final displacement of approximately 149.94 mm. The maximum dissipated energy was 1,419.840 kN·mm in the push direction and 1,510.006 kN·mm in the pull direction, while the EVDR ranged from 5.96% to 16.10%. The experimental ductility was 11.07 in the positive direction and 10.15 in the negative direction. Damage developed progressively from panel cracking, vertical and local diagonal cracks, and panel–column separation to localized damage at the frame joints. The specimen capacity was approximately 3.73–4.11 times the theoretical bare-frame capacity of 7.56 kN. A limited evaluation using SNI 9273:2025 based on the envelope curve resulted in drift limits of 0.19% for Immediate Occupancy, 0.82% for Life Safety, and 1.05% for Collapse Prevention. Although the response exceeded the adopted Collapse Prevention limit, the specimen retained lateral resistance up to approximately ±4.90% drift, indicating additional post-yield deformation capacity. The results indicate that precast ferrofoam concrete panels have potential for further development as a lightweight infill-wall alternative for residential frames in earthquake-prone regions.
