Abstract

Research about mechanical analysis of limestone in District Jaya, Lhong, and Lhoknga has been done from Dec. 2011 to Mei 2012. This study aim is to classify the limestones based on physical and mechanical tests as well as identify opportunities limestone utilization in accordance with the SII 0378-80 as a condition of quality natural stone for building. Research have been done by testing compressive strength, modulus Young, wear, specific gravity, porosity, and absorption. The result shows that the limestones are qualified natural stone for building the foundation, curbstone, stone and ornamental stone or paste.

Abstract

Aceh is one of province that has abundant natural resources, which consist of natural resources which can be renewed or not renewed. With the increasing human population, especially in Indonesia, resulting in increasing human needs of various sectors, particularly in the construction sector. In the development activities required a lot of materials-minerals, such as sandstone, limestone, serpentinite rock which serves for a variety of needs in development activities. In District Indrapuri (Aceh Besar Regency), Tangse (Pidie Regency), and Beutong (Nagan Raya Regency) finding of the serpentinite rock is abundance. Meanwhile, in line with the rapid physical development in Aceh and its surroundings, then the needs of rock as building materials will increase as well. Research done by physical properties (specific gravity, absorption, porosity), and mechanical properties (testing compressive strength, wear/abrassion) of serpentinite rock to determine its quality as a building material. The results show that the serpentinite rock contained in District Indrapuri, Tangse, and Beutong for the building according SII 0378-80 is qualified for the foundation, curb stones, and ornamental stones or paste stones.

Abstract

A soil and rock slope assessment survey was conducted along Bireun – Takengon main road in Aceh Province, Indonesia. The slope assessment survey was carried out to determine the geological condition, verify and identify the potential areas of slope failure and to study what type of slope stability and protection method could be applied to the road. Several research methodologies were conducted in the field such as rock and soil identification, and slope assessment. The survey was conducted in four selected areas along Bireun – Takengon main road. In study area I, soil creep occurred because of a presence of montmorillonite clay. The mitigation methods to reduce soil creeping in this area are building a retaining wall and pile. The shotcrete, wire mesh, net rock bolting, and rock removal method is suitable to apply in study area II. The shotcrete and soil nails were used because the type of rocks in those areas is sedimentary rock such as shale, sandstone, siltstone, and a boulder of a volcanic rock. The same approach shall be applied in study area IV. study area III was the best spot to learn about the mitigation approach for slope stability and provides many lessons learned. Aceh Province experience active tectonic movement, high intensity of rain, geological structures, a high degree of weathering, and high intensity of earthquake,as primary factors which trigger landslides. The techonology of slope stabilizing and protection methods can be applied to mitigate landslides.
