Anomalous Amplitude Attenuation (AAA) is a method to process seismic data with multilevel processing (multi step flow). AAA is indicated for identifying anomalous seismic amplitude (amplitude noise) such as: spike noise, noise and noised trace. AAA…
The study of noise level distributions have been done in Baiturahman Mosque area. The measurement take place in different places (near the mosque), times and days. The point of the measurement is choosing based on the high appereance level of noise…

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…
Raindrop motion is affected by several factors; one of which is wind speed during the rain. This study is aimed to investigate that impact by using mathematical simulation with Fortran and Matlab. Raindrops arrive on the Earth’s surface at their…
Abstract: Indonesia based on the value of irrigation efficiency standards by 65% Irrigation Planning. This value when compared to some countries in Asia were still much greater because of the efficiency of existing irrigation network was limited in…
