One of the most common inhibiting factors in the archipelago is the lack of availability of material resources and human resources. One of the options is the use of lightweight concrete precast using materials around the islands. The local material which is widely distributed in North Maluku is pumice but it has not been used maximally because so far it has only been used as pile material. This study aims to analyze the effect of partial substitution of pumice on fine aggregate in a concrete mixture. This research was carried out experimentally in a laboratory using UTM and divided into 2 stages. Stage 1, designing and analyzing concrete mix using pumice compared without using pumice, Phase 2 testing using concrete beam dimensions of 600x150x100 mm with an inter load of 150 mm. Beam test results show that the limited use of pumice in a concrete mixture does not greatly affect the strength of normal concrete beams, as indicated by the deflection value and strength of concrete blocks that are almost as large.
