This research examines the boundedness of the Bessel-Riesz operator in Lebesgue spaces defined on metric measure spaces. The Bessel-Riesz operator is a convolution of the Bessel-Riesz kernel and functions in Lebesgue spaces. Before proving the boundedness of the Bessel-Riesz operator, it is first shown that the Bessel-Riesz kernel satisfies the membership condition in the L1 space. Furthermore, the proof also utilizes the boundedness of the Hardy-Littlewood maximal operator in Lebesgue spaces. By leveraging the membership property of the Bessel-Riesz kernel in the L1 space and the boundedness of the Hardy-Littlewood maximal operator, the Bessel- Riesz operator is shown to be bounded from Lp to Lp. %Z Malahayati, S.Si., M.Sc. dan Aulia Khifah Futhona, S.Si., M.Sc
