Indonesia has thousands of ethnic groups with a variety of traditional buildings. Traditional buildings made of wood almost all experienced problems of material damage due to insect attacks and weathering due to weather influences.The community tends to dismantle building elements that have been damaged by hoisting insects. This happens because of the lack of knowledge about techniques in repairing or retrofitting wood structures. Wood material is susceptible to problems with elemental damage due to weathering and insect attacks. Damage to the structural elements of the wooden beam does not occur as a whole but only in certain areas. To maintain the strength of the wood in order to carry the burden, it is necessary to strengthen only the damaged area. So the structural elements of the wooden block do not need to be replaced in total but only on the damaged part. Testing the tensile strength of the flexural strength of the whole Tectona grandis wood block as many as 6 pieces, 6 pieces of Teak wood without adhesive, Tectona grandis using 6 pieces of adhesive with a size of 120 x 8 x 6 cm, and Tectona grandis wood as 6 pieces of adhesive with the size 10 x 4 x 6 cm, and the adhesive used is epoxy glue. The results of the study stated that the maximum flexural strength is occurring in Teak wood beams with adhesive (D-1, D-2, D-3) able to have stronger flexural strength of 59.8455 N/mm 2 , 52.22533594 N/mm 2 , 54.54848438 N/mm 2 , compared to solid beams (F-1, F-2, F-3) of 39.72684375 N/m 2 , 53.01527344 N/mm 2 , 60.58877344 N/mm 2 . This research also shows that the connection of Teak wood blocks with adhesives has better flexural strength.
