Abstract

Bambu merupakan material konstruksi ramah lingkungan yang mempunyai peluang besar untuk dikembangkan pada bangunan hijau. Kondisi ini dikarenakan bambu memiliki kharakteristik mekanik yang baik. Meskipun demikian, penggunaan bambu belum dapat dimaksimalkan karena sedikitnya informasi terkait desain struktur bambu termasuk geometri dari sambungannya. Penelitian ini dilakukan dengan tujuan untuk menentukan jarak kritis baut pada sambungan bambu Gombong (Gigantochloa Pseudoarundinasea). Penelitian dilakukan secara eksperimental berdasarkan standar ISO N22157. Berdasarkan hasil penelitian didapat nilai rata-rata kadar air Bambu Gombong  memenuhi persyaratan pengujian kuat geser dan kuat tumpu yaitu kadar air < 15%. Nilai kuat geser rata-rata Bambu Gombong sebesar 5,89 MPa. Sedangkan rata-rata kuat tumpu Bambu Gombong adalah sebesar 36,47 MPa. Berdasarkan nilai kuat geser dan kuat tumpu dilakukan analisis terkait jarak baut pada sambungan bambu dan didapatkan jarak kritis baut pada sambungan Bambu Gombong dari ujung batang bambu tanpa ruas ke baut adalah sekitar 4,27 D atau 4,27 kali diameter baut. Hasil penelitian ini sangat penting sekali sebagai dasar dalam desain struktur sambungan bambu yang menggunakan baut sebagai alat sambungnya.
