Abstract

The main issues that were examined in this study is the modulus of elasticity bamboo betung with variable length. The purpose of this study was to measure the modulus of elasticity on bamboo betung with variable. Modulus of elasticity in bamboo shows the flexibility for using in a various fields. In this study the bamboo is made into small girders with a uniform thickness and width are respectively 0.8cm and 1.5cm. The length of the bamboo that is used in this study are the 50cm, 60cm, 70cm, 80cm, 90 cm, 100cm. To determine the elasticity of the bamboo it is provided with a load in the middle position. From the research results obtained showing the longer bamboo the greater flexibility gained linearly elastic modulus is 1.0122E+10N/m2. Keywords: bamboo, girder, modulus of elasticity.

Abstract

One potential area that have encountered in Indonesian society is brown sugar. There are various types of sugar including coconout sugar, palm sugar, ants sugar and others. Another interesting thing is examined in this study relates to the mechanical properties of palm sugar that is the compressive strength of the palm sugar. Palm sugar is made from sugar palm sap heating on volume of 600ml with a variation of the time is 26 minutes, 27 minutes, 28 minutes, 29 minutes and 30 minutes. The mechanical properties studied were compressive strength of palm sugar. These parameters were measured to determine the maximum size of an acceptable burden the palm sugar. The compressive strength of the palm sugar palm juice on the heating time 30 minutes, namely: 0.115218MPa. From the research results obtained showing a variable effect on the mechanical properties of palm sugar because the longer the heating time, the greater compressive strength. Palm sugar compressive strength of the observed increasing with time is lengthened. Keywords: palm concentrate, palm sugar, compressive strength, the heating time.
