		abstract={At the moment, the use and utilization of composite materials as an alternative to metal
materials in the field of engineering has begun to grow. This is in line with the increasing use
of metal materials that are increasingly widespread such as property, household tools to
reach the small-scale, and large-scale industrial sectors.
The purpose of research is to identify the effects of soaking times of 1, 2, 3, and 4 hours
on hemp fiber-reinforced composites with alkaline treatment of polyester matrix on the
tensile strength. The research method used was an experimental method. The results obtained
from the tensile test of hemp fiber-reinforced polyester resin with an alkaline treatment time
of 1 hour generated the average tensile stress of 31.42 MPa, 2 hours generated the average
tensile stress of 35.44 MPa, 3 hours generated the average tensile stress of 36.19 MPa, and 4
hours generated the average tensile stress of 29.54 MPa. The highest tensile stress strength
value was obtained at 3 hours soaking time and the lowest was 4 hours.}
