Abstract

Di Pulau Lombok sering terjadi gempa besar akibat pergerakan Flores Back Art Thrust yang banyak menimbulkan beberapa kerusakan bangunan di sekitar Desa Kekalik Jaya. Selain itu Desa Kekalek Jaya memiliki jumlah penduduk sangat padat yaitu 14800 jiwa/km2, rumah dan bangunan yang berhimpitan, dan kurangnya tanah lapang untuk tempat penyelamatan diri jika terjadi bencana gempa. Untuk itu perlu memberikan pengetahuan tambahan kepada para tukang tentang perkuatan bangunan dengan ferrocement sehinga lebih tahan terhadap beban gempa. Pelaksanaan diawali dengan survey untuk berkoordinasi dengan pihak aparat desa, kelompol tukang serta pengumpulan data-data permasalahan yang ada dari masyarakat di Desa Kekalik Jaya. Selanjutnya dilakukan sosialisasi tentang metode perkuatan bangunan rumah sederhana dengan ferrocement. Hasil survey awal menunjukkan bahwa hanya sebagian kecil para tukang yang pernah mengetahui tentang dinding ferrocement bahkan ada beberapa tukang belum pernah mendengar sama sekali. Hasil kegiatan sosialisasi ini juga menunjukkan tingkat antusias dan respon peserta atas pertanyaan-pertanyaan tim pengabdian setelah usai pemaparan materi

Abstract

The use of natural coarse aggregate in large-scale concrete production can be avoided using recycled coarse aggregate as a substitute for natural aggregate. However, using recycled coarse aggregate can generally affect the quality of concrete. The excessive interfacial transition zone (ITZ) is formed due to the old mortar that is still attached, which is the weakest contact zone in recycled aggregate concrete. The addition of polymers such as Styrene Butadiene Rubber (SBR) to the recycled aggregate concrete mixture is expected to increase the strength in this area. The addition of SBR content of 0%, 2.5%, 5%, and 10% to the weight of the mixture water was carried out to review the performance of concrete in terms of its physical properties and mechanical properties. The coarse aggregate used came from recycled coarse aggregate using the Heating-Grinding-Acid Solvent (H-G-A) method. The results of the study show that H-G-A concrete with an additional SBR content of 5% exhibits superior quality compared to normal aggregate concrete. The addition of SBR shows a denser ITS area resulting in the quality of concrete increases.
