Abstract

Bamboo can be used in construction planning because based on its properties, the mechanical strength of bamboo has high tensile strength and high compressive strength so that it can be used for soil reinforcement. Bamboo which has good quality will also have good mechanical properties as well because bamboo which has good compressive strength, laboratory results also show that bamboo has good tensile strength as well. Thus, there is a correlation between compressive strength and tensile strength in bamboo which is an environmentally friendly material as a soil strengthening material. The data in this study were using bamboo Apus and Javanese bamboo. Because bamboo is often used in industry and is easily available in Semarang. This study uses a simple linear method (Ordinary Least Squares). Simple linear regression model is one of the regression models that are often used in regression analysis. The dataset divided into 2 part, namely by comparing 60% of training data and 40% of testing data. The result from the data testing showing linier regression (least squares) estimate becomes very sensitive to random errors in the observed target, producing a large variance and the following results are obtained Correlation Coefficient 0.99607873, Mean Squared Error 12. 58799, Variance Score 125.60. The results show that the correlation coefficient is 0.99607873, it's mean that the linear model is close to number 1 meaning that this model is a good model because the correlation coefficient value is close to 1 so there is a positive relationship between or positive correlation between the compressive and tensile tests.
