This research connected the gravity value with the existence of andesite rock with good quality physics. Based on gravity mapping, high gravity anomalies in southern Lampung relate to igneous rocks, especially granite and granodiorite plutons, meanwhile andesite rock in medium gravity anomalies. Further geological observation and test of andesite rock physical properties become very important, in order to support the fulfilment of quantities with good quality for the acceleration of development of the Sunda Strait area. The andesite potentials in the Tarahan and Bakauheni areas are predominantly located on the medium Bouguer anomaly. The results of petrographic analysis showed three types of rocks, namely hornblende andesite, basalt amphibolite and tuff. The magma series based on the Atomic Absorption Spectrometry(AAS) test results on the three samples shows the calc-alkaline magma series. While from the testing of the physical properties of rock shows properties that meet the standard SII.0378-80 by the ultimate of the strength, force value range between 1125 to 1558 kg/cm2, in which the material can be used for medium to heavy buildings raw materials.
