Analysis Test of Fine Aggregates at the Upstream of Jeneberang River

Abstract

The purpose of the research was to find out: 1) mining location distribution and 2) fine aggregate gradation originated from construction material mine locations located at the upstream of Bili-bili reservoir. The research combined descriptive and experimental research. Descriptive research was conducted to map the distribution and area of construction material mining, whereas experimental research was conducted to analyze fine aggregate gradation of materials originated from the mining areas. The research result indicated that 1) Lanna Village with two mining points, Tambang Luas and SP1, became the largest mining location with total mining area of more than 97 Ha. SP4 in Bontokassi Village was no longer became a mining area since it cannot be accessed by the miners; 2) Gradation analysis in mining materials based on fineness modulus for Tambang Luas, SP1, and SP3 locations were in a fine category. Whereas, SP2 and SP5 were in the rough category. Based on the aggregate zone, Tambang Luas, SP1, and SP3 were located in Zone 2 relatively rough materials, whereas SP2 and SP5 were in zone 1 rough.
