Abstract
The column is an important structure element because the failure of column will have direct impact to other structure components, so that the ruin of structural column is an important thing to be observed. The research use experimental method. The aim of this research is to get improving of strength and ductility in column specimen which is given the FRP strengthener (Fiber Reinforced Polymer) compared with original column. There are 3 specimens used. They are C-1 (original column), C-1G (column with GFRP strengthener 1 layer) and C-1C (column with CFRP strengthener 1 layer). From the research got the increasing Pmax toward original column is 33,52% and 54,97%, the increasing of dmax is 6,65% and 81,18%, also the increasing of Mmax is 32,41% and 55,36% each for C-1G and C-1C. Ductility indexes taken on three positions are plastic hinge zone, a half high of column effective and as high as column effective. From analyze result got the increasing of displacement ductility toward C-1 for C-1G is -34,20%, -28,46% and -12,74% and C-1C is 64,48%, 108,74% and 118,68%, each for plastic hinge zone, a half high of column effective and as high as column effective. In column C-1G happened the decreasing of ductility value because there has been destruction in column head when the test was running.

Abstrak
Kolom merupakan elemen struktur penting karena kegagalan kolom akan berpengaruh langsung terhadap komponen struktur lainnya , sehingga kehancuran kolom struktural merupakan hal yang penting untuk dicermati . Penelitian ini menggunakan metode eksperimen . Tujuan dari penelitian ini adalah untuk mendapatkan meningkatkan kekuatan dan daktilitas dalam spesimen kolom yang diberi FRP penguat ( Fiber Reinforced Polymer ) dibandingkan dengan kolom awal . Ada 3 spesimen yang digunakan . Mereka adalah C - 1 ( kolom asli) , C - 1G ( kolom dengan GFRP penguat 1 lapisan ) dan C - 1C ( kolom dengan CFRP penguat 1 lapisan ) . Dari penelitian mendapat peningkatan Pmax menuju kolom awal adalah 33,52 % dan 54,97 % , peningkatan dmax adalah 6,65 % dan 81,18 % , juga meningkatnya Mmax adalah 32,41 % dan 55 , 36 % masing-masing untuk C - 1G dan C - 1C . Indeks daktilitas diambil pada tiga posisi yang zona sendi plastis , setengah tinggi kolom yang efektif dan setinggi kolom yang efektif . Dari hasil analisis mendapat peningkatan daktilitas terhadap - C 1 untuk C - 1G adalah -34,20 % , -28,46 % dan -12,74 % dan C - 1C adalah 64,48 % , 108,74 % dan 118,68 % , masing-masing untuk zona sendi plastis , setengah tinggi kolom yang efektif dan setinggi kolom yang efektif . Dalam kolom C - 1G terjadi penurunan nilai daktilitas karena sudah ada kerusakan di kepala kolom saat tes berjalan .
