dc.description.abstract Abstract: Tanjung Bunga Beach, Makassar city, is a coastal development area, temporarily growing rapidly with infrastructure development. Based by study that has been done, grain size analysis of Tanjung Bunga beach sediments was classified in fine sand (0.125-0.25 mm), medium sand (0.25-0.50 mm), and coarse sand (0.50-1.00 mm). Petrographic analysis of 15 samples which are fine sand (6), medium sand (4) and coarse sand (5), in three drilling sites with 5 meters depth, found quartz mineral composition from 20 – 25%, hornblende bertween 5 – 20%, pyroxene 5 – 15%, Plagioclase 5 – 15%, Orthoclase 5 – 15%, biotite 10 – 20%, and opaque minerals 10 – 25%. The result of CBR laboratory test barrier values of Fine Sand is 2451,36 – 2498.77 kg/cm3, Sand Medium 2015.05 – 2195,57 kg/m3, and Coarse Sand 2460,62 – 2495,52 kg/m3, petrographic analysis after barrier test on fine sand, crack minerals up to 75 – 100%, dikes minerals up to 50 – 80%, and shatters minerals up to 50 – 60%, were in Medium sand is crack minerals up to 70 – 100%, dikes minerals 60 – 100%, and shatters up to 20 – 75%, and coarse sand crack minerals up to 60 – 100%, dikes minerals 40 – 70%, and shatters minerals up to 20 – 50%. Based by petrographic observation, was found similar crack mineral in fine sand, medium sand, and coarse sand, dikes mineral is more on medium sand, shatters mineral in fine sand is more than coarse sand where CBR test values in fine more lower than coarse sand with were has highest value. More cracked minerals are Quartz and least are opaque minerals. Orthoclase, Biotite, and Plagioclase are minerals has high shatters percentage than the other minerals en_US
