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

People often perceived that weather pattern is irreguler and unpredictable. Therefore it is necessary to investigate the relationship between position of the sun above earth's surface and the change on rainfall patterns in the region of Banda Aceh and surrounding. Aceh region is located at the tip of Sumatra island and at the perimeter of three major oceans. This location greatly affect rainfall patterns in Banda Aceh and Aceh Besar. The aims of this research are to determine the variation in weather pattern, especially rainfall and to draw up a general pattern of weather oscillation, especially rainfall in the region of Banda Aceh and Aceh Besar. The position of sun relative to Banda Aceh was then visually sketched on a world map. The map is used to analyze relations between rain frequency, duration and time with sun’s position over land and sea, based on the rain pattern condition in six months from Desember 2013 until Mei 2014. The result showed that from Desember until February, rain mostly occured at night and water vapor came from Indian Ocean. Meanwhile in March and May, rain are more common in the morning when the sun’s position was above Indian Ocean and Sea of Bengal. However in April rainfall occur during the day, because of evaporation was brought from the South China Sea.
