Cosmic Microwave Background (CMB) is a background radiation that is coming from fotons in the early universe (at the age of the universe 300.000 years) in a distribution of blackbody radiation. The discovery of CMB give a big hope to astronomical science remembering its properties that cosmological representative, extend everywhere in our universe. Astronomers hope those CMB observation and a correct measurement would give us any information about universe from past to present day. Galaxy clusters, in the other hand, are the most massive object in our universe were stable in its own gravitational force. The lest dense area in the galaxy cluster consist of hot gas. CMB obeservation with galaxy cluster's hot gas as a cover giving us Sunyaex Zel'dovich Effect (SZE). This SZE termal mechanism change the CMB spectrum. In a different way observation, hot gas well observebed in X-ray as an surface brightness. Joint analysis of X-ray and SZE data giving us an angular diameter distance thal allow us to measure Hubble constant, one of an important cosmological parameter. Nevertheless, Hubble constant from this measurement method contain a big error bar. Hubble constant measurement have been done by Bonamente (Bonamente et.al 2007) using joint analyasis X-ray and SZE data of 38 massive galaxy clusters at redshift 0.14 < z < 0.89 , obeserved with both Chandra X-ray Observatory and SZE imaging system at the BIMA and OVRO interferometric arrays. This bachelor thesis will give a few approximation to the error bar generated in the Hubble constant measurement using this SZE method by data checking and localize its uncertainties.
