- Joint is one of the most important components of a structure. The strength of a structure cannot be separated from joint�s strength. Especially for wooden joint with dowel has several advantages, including wooden dowel is made from biological source that can be recycled in nature so that the wood can be decomposed perfectly. Besides, due to the suitable characteristic between dowel and wooden material will make the joint more optimal if there is a change in temperature and humidity. On the other side of scheme and analysis, wooden dowel joint has constraint, where wooden dowel joint has different failure modes from wooden nails joint or wooden bolts joint. Because of that, research about wooden dowel joint need to be developed and also considering in SNI-05 2002 the scheme of wooden joint is especially just for wooden joint with bolts or nails. In this research, loading of LVL (Laminated Veneer Lumber) Sengon timber joint used Nangka wooden dowel ( specific gravity 0,61 ), Walikukun ( specific gravity 0,9) and Ulin (specific gravity 0,98) are done with static monotonic. Besides that, joint variations are also done for dowel with diameter 12 mm, 16 mm, and 20 mm and corner variations are wooden connection sustaining load in direction perpendicular to grain and sustaining load in direction parallel to grain. In the analysis, 5% offset method is used to determine the yield point, while lateral load resistance theoretically analyzed based on SNI-05 2002 and EYM (European Yield Model). The results showed that the highest lateral load resistance sequentially is joint using diameter 20 mm (26,7 kN), 16 mm (15,98 kN) and 12 mm (9,71 kN). Based on the variation of specific gravity, the highest lateral load resistance sequentially is joint that using Ulin wooden dowel (16,2 kN), Walikukun (15,98 kN) and Nangka wooden dowel (9,71 kN). Wooden connection sustaining load in direction perpendicular to grain (13,38 kN) has lower lateral load resistance than wooden connection sustaining load in direction parallel to grain (15,98 kN). In terms of initial stiffness and ductility, the highest stiffness and ductility sequentially is joint with diameter 20 mm, 16 mm and 12 mm. For variation of specific gravity, the highest ductility and stiffness values sequentially is joint using Ulin wooden dowel, Walikukun and the lowest ductility and stiffness value is Nangka wooden dowel. Wooden connection sustaining load in direction perpendicular to grain has higher ductility and initial stiffness than wooden connection sustaining load in direction parallel to grain. The experiment result of lateral load resistance is greater than theoretical SNI and EYM. The average value of lateral load resistance based on SNI is ± 64,6% of the experimental value, and EYM is ± 78,45% of the value of the experimental lateral load resistance. The experiment result shows that failure modes IV (two plastically joints occurred) this is appropriate with theoretical calculation of EYM. From the dowel bending test series generate empiric equation to calculate the value of dowel bending yield moment (My) for Nangka, Walikukun and Ulin wooden that is
