Abstract
Commonly house’s damage under earthquake is because their capacity inadequate to prevent from collapse, and the masonry wall system is not designed to resist the earthquake force. However, masonry infill wall is commonly used as partition and to separate large area with a purposed. Interaction between frame and masonry infill wall are not good connected to prevent building damage from earthquake. To understand the interaction between frames and infill wall can be simulated by numerical method or by Macro-modelling approach. The purpose of this numerical study is modelled a frame as a single element, a masonry infill wall as a plate element, and an interface between frame and masonry infill wall as an elastic spring. The concept of modelling depends on material parametric provided and the number of elements. Modelling with computational software facilitate to create material element and model and this modelling is conducted by Tohoku-coast NS time history seismic. The result shows the frequency parameter expressively increase from frequency on frame model to frame with infill wall model, or the time period parameter significantly reduce with the addition of infill wall. By the addition of mortar thickness which increased the stiffness also affect the frequency parameter and maximum displacement. The thickness of mortar brought the optimal value to good response is recommended with thickness of 0.5 cm to 1.5 cm. The finding is that infill wall gives significant influence on frame response if the interface of frame and infill wall designed with good material characters.

Sand beach’s is available in huge quantities in many country side but the quality still needs to be investigated before using in construction. Sand beach can drive to corrosion on the steel reinforcement thus damaging the building. Previous studies have shown that bamboo has good tensile strength and flexural strength. This study aims to examine the use of bamboo as an alternative reinforcement in concrete beam made from sand beach’s as fine aggregate. Sand beach of loto is one of three quarry sources chosen as a fine aggregate in making test specimens reinforced concrete beams as subjected study. Concrete beam specimens consist of 12 beams with 10x15 cm and a length of 120 cm of size. control beam (BN) was made from normal aggregate with steel reinforcement. the Variation of beam specimen (BF1, BF2, BF3, BF4, BF5) was made from sand beach’s fine aggregate with bamboo reinforcement. Bamboo that applied as concrete beam reinforcement was Wulung bamboo kind that have about 3 years of age. bamboo’s tensile test results were obtained average tensile strength is 185 MPa. The flexural test for all beam’s specimen was carried out with two-point loads to determine the amount of deflection that occurs in each beam. Analysis of relations of load-deflection was carried out to each beam specimen from the experiment result. test results showed that the bamboo reinforcement worked as well expected and no splitting occurred, so that the bamboo reinforcement appeared broken when ultimate strength exceeded. The maximum strength was obtained in BF5 beam specimen with an ultimate load 21,5 kN. Flexural test results show that on beams with steel reinforcement tends to occur flexural cracks while on beam with bamboo reinforcement also found shear cracks.

Abstract
This research aims to develop decision making models for Multi Criteria Decision Making (MCDM) with Adaptive Interval Fuzzy Analytic Hierarchy Process (AIVFAHP) and Adaptive Interval Fuzzy Technique for Order Preference of Similarity Ideal Solution (AIVFTOPSIS) integration methods by constructing a decision-making model using trapezoid fuzzy number. The strength of the AIVFAHP method is to consult the value of logical consistency in the assessment. This logical consistency is to calculate the assessor and determine the costs in multi-criteria decision making. AIVFTOPSIS is based on the principle that the chosen alternative should be close to a positive ideal solution and far from the ideal solution. Contribution of this research is to conduct a research of decision making with Adaptive Interval Value Fuzzy Multi Criteria Decision Making (AIVFMCDM) and to improve interval points by modifying the midpoint and degree on the trapezoid fuzzy number function. This modeling provides more accurate, more effective linguistic representation and flexible in determining the point of the interval for optimal results. The research produced a new decision-making model based on the Adaptive Interval Trapezoid Fuzzy Number (AIVTFN) and recommendations for improvement of e-learning indicators.
