Experimental Study of Bamboo As A House Retrofitting Material For Developing Countries

Earthquake is one of the main natural disasters which frequently occur in West Sumatra. Large earthquake September 30, 2009, has caused damage to the structure and caused many casualties. Due to this condition, this research was made to study bamboo as a house retrofitting material for developing countries.  Mechanical and physical properties such as moisture content testing, testing density, testing of compressive strength and tensile strength were conducted. It is obtained from the test results, the highest compressive strength and tensile strength are 94.958 MPa and 183 MPa, showed by Betung bamboo. Shaking table test are also undertaken to investigate the seismic behavior of bamboo masonry wall. Two degree of masonry walls, 60° and 90° are tested in order to check the strength of masonry wall by direction of the coming of an earthquake. From the shaking table test, it was observed that a 60° masonry wall showed a better seismic performance than those of a 90° masonry walls. Small cracks were observed at 90° masonry walls after 20 seconds, while there was no crack at a 60° masonry wall. As a result of these test, using bamboo as a house retrofitting material could be chosen, both of technically and economically

Pemasangan Tali Polypropylene Band Mesh sebagai Retrofitting Material pada Rumah Tinggal di daerah Pisang, Kota Padang

Kota Padang termasuk salahsatu kota dengan tingkat kerentanan yang tinggi terhadap gempa. Kejadian gempa tahun 2009 yang lalu telah merubah banyak hal terhadap peta kegempaan sebelumnya. Oleh sebab itu penting bagi masyarakat untuk mengetahui aturan membangun yang benar dan teknologi perkuatan apa yang bisa diterapkan untuk menambah perkuatan pada bangunan. Kelompok yang menjadi mitra pada pengabdian ini adalah kelompok tukang bangunan di daerah Pisang, Kota Padang, yang sedang membangun sebuah rumah tinggal. Adapun pemilihan bangunan ini karena telah memenuhi persyaratan standar bangunan SNI untuk rumah layak tinggal. Tujuan dari kegiatan pengabdian ini adalah untuk lebih mudah dipahaminya metoda perkuatan bangunan dengan pemasangan tali Polypropylene Band Mesh (PPBM) ini baik oleh para tukang bangunan maupun masyarakat pada umumnya. Metoda yang akan digunakan dalam kegiatan ini adalah survey lansung ke lapangan, memberikan penyuluhan melalui presentasi, dan metoda pemasangan lansung tali PPBM pada bangunan rumah tinggal, dimana dengan ini diharapkan para tukang bisa mendapatkan ketrampilan dan ilmu pengetahuan baru dalam bidang konstruksi bangunan, terutama untuk bangunan yang aman terhadap gempa. Dengan adanya kegiatan ini, kelompok tukang bangunan semakin bertambah pemahaman dan ketrampilannya tentang konsep membangun yang benar dan konsep perkuatan bangunan dengan tali Polypropylene Band Mesh. Sehingga penggunaan tali ini dapat dijadikan rekomendasi sebagai salahsatu alternative bahan perkuatan bangunan agar aman terhadap gempa
