Nowadays, there are more usages of additional materials for increasing the quality of concrete such as coming from gray and plant fiber. There are any kinds of bamboo in Merauke Regency which has not been well used by the society. Bamboo that is planted in Merauke Regency can be used as the alternative additional material of plant fiber and as the changing of steel carcass. This study intends to know the quality of concrete strength by adding plant fiber and bamboo carcass. The methodology consists of experimental method by using the variety of bamboo fiber and carcass. The variety of bamboo fiber is as 0.5% and 1%. The evaluation and analysis of cleft pull strength uses SK-SNI 03-2491-2002, concrete defraction strength uses SK SNI 03-4431-1997, and concrete pressure strength uses SK SNI 03-6429-2000. The samples consists of 30 units with cylindrical shape for cleft pulling strength and concrete pressure strength tests; and 15 units with block shape for concrete fraction strength test. Result shows that bamboo caracass in concrete is significantly affected and it can be seen from the increasing of diffraction strength which the normal concrete is 3.321 MPa and on bamboo carcass type 3 is as 19.925 MPa. However, bamboo carcass type 3 can be used as the changing of steel carcass mainly for non-structural building Keywords: concrete, concrete strength, bamboo fiber, bamboo carcass I. INTRODUCTION Nowadays, the development of technology is very fast. It is due to there are many ideas and new innovation [1][2] such as the development of concrete technology. Concrete has high enough of pressure strength but it is weak to the pulling. Therefore, the usage of concrete is always related to the material which has high pulling strength such as steel. Concrete with steel carcass is more used as building material because it has very high pulling strength value but in real, the high pulling strength value causes the new problem due to the the steel carcass is as the non-renewable mineral material so it will to the last anytime Revised Manuscript Received on September 2, 2019.

It is due to some factors such as to be easily attacked by insect, easily to be burned, and the esthetic value is less appreciated. Based on the some factor as above, there are any advantages in using bamboo such as the pulling strength is relatively high, the growth is fast and easily to be planted. Serapu is a village in Merauke Regency; it is part of Semangga District where ±15 km from city center is. Serapu village has the potency of bamboo but it is not well used by the society surrounded it. This study intended to find the changing material as the natural yield such as bamboo. Bamboo is as natural yield that has very high pulling strength. Rivani et.al. [5] said that the addition of 0.25% on bamboo skin cleft on normal concrete mix has caused the increasing of concrete block strength capacity significantly. It is followed by the increasing of ductility. The percentage value is as the optimum content of bamboo cleft addition which is randomly distributed in the test. The addition of 0.75% and 1% from mix weight of normal concrete has decreased the strength of sample block. The decreasing of strength is caused by the decreasing of mix work ability. Gale [6] with the title: Crack which is happened on the beginning of crash process is diffraction crack which is marked by straight upright crack pattern [7]. Generally, the crack is happened when the load reaches more than 90% of theoretical load or about 70% of crash load. The beginning crack is happened on loaded area at surrounded roll supporting, then the crack is happened in the middle of stretch and for the next in surrounded of joint and on the contrary. Putra et.al. [8] with the title: “Capacity of Bamboo Carcass Concrete Diffraction” expressed that ultimate pulling tension of Petung bamboo without nodia (f 0 ) on 640 MPa and ultimate pulling tension of Petung bamboo on 525 MPa produced ultimate mean of diffraction moment from experiment was more than 24.7% from mean result of theoretical analysis on Petung bamboo carcass without nodia and on Petung bamboo carcass with Nodia the experiment mean result is more than 39.4% from the analysis mean result, so bamboo can be used as the changing of steel carcass on concrete plat by holding the pulling force.
