ABSTRACT

In this increasingly advanced era, the more development is carried out, the increasing scale of development. It shows more and more concrete needs in the future. The purpose of this study is to find out and analyze the addition of water hyacinth fiber as a mixture on concrete. Data analysis methods begin with the investigation of cement material, fine aggregate, coarse aggregate, and water hyacinth material. Concrete is added with water hyacinth fiber with addition variations of 0%, 1%, 3% and 5%. Test object used in the form of a cylinder with size ø 15 cm x 30 cm. Concrete mix design uses ASTM method. In the process of making water hyacinth fiber begins with cutting the water hyacinth by 3-5 cm, then milling it into fiber. The next step is drying into the sun and then into the oven at 150ºC. From the results of the research conducted at the Civil Engineering Laboratory of Lamongan Islamic University, the results showed that there was a decrease in strength in the variation of the addition of water hyacinth 1% and 3% but experienced an increase in the 5% variation. It is known that the correlation of concrete compressive strength at 28 days is 0% at 86.27 Kg/cm2, 1% at 60.66 Kg/cm2, 3% at 55.27 Kg/cm2 and 5% at 57.97 Kg/cm2.

Keywords: water hyacinth, concrete, compressive strength.
