AAA is indicated for identifying anomalous seismic amplitude (amplitude noise) such as: spike noise, noise and noised trace. AAA is a filter applied to the data in the frequency domain, range, both in CMP/CDP, offset or gather shot. Processing of the data depends on how the sensor (the geophone) receives seismic waves, and then set the data back into the format demultiplex (SEG-Y) and then processed according to the rules (flowchart) seismic reflection processing.This method has been applied to improve the old seismic data of an exploration company in prospecting the unseen structure in prospecting the hydrocarbon trapped within sedimentary rock subsurface.

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.

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 terminal velocities which depend on their size. Raindrop falling motion could be analyzed with net force equation (Newton’s second law). In order to determine velocity and position equations as a function of time, coefficients in those equations were fitted and compared toraindrop model developed by Boxel in 1997. In this study, equations used are fitted to both large and small size raindrops. Values resulted by equation for large size drops agreed with experimental data. Wind speedcauses the terminal velocities of raindrops to get larger, and so does their kinetic energy. In that condition, raindrops fall with certain inclination angle. The stronger wind speed, the larger raindrops’ inclination angle and their kinetic energy are when hitting soil surface. Therefore it increases the risk of soil erosion at place where the soil is unstable. Through this study, speed and direction of raindrop when hitting soil surface could be investigated in order to decrease the risk of avalanche at high risk area.

Carsington Dam in Derbyshire UK had been chosen as case study for this paper. The data obtain in the analysis was a part of postgraduate study project of the author. This dam failure is an example of an end-of-construction failure in an earth-fill slope brought from deficiency of design. In term of stability for pre-construction analysis, soil parameters of drained shear strength are used based on the original designer. In terms of porewater pressure, because there are no assumption values by the designer can be found as information in literature, range values of ru are used in the analysis. For safety factor calculation, SLOPE program version 18.2 was used follow with wedge analysis method for comparison purpose. Next, for post-failure analysis, the soil parameters combinations between peak, post-peak and residual were used to calculate the factor of safety. From the analysis of initial failure, the dam’s designer used peak strength parameters whereas for post-failure, residual strength parameters was used in boot and yellow clay, and peak strength in the boot. The safety factor at the time of failure was approximately 0.901.Keywords : earth-fill, slope, pre-construction, post-failure.Abstrak: Artikel ini menjelaskan tentang proses keruntuhan bendungan air dikarenakan oleh tingkat stabilitas lereng yang rendah.

Each type have different cost risk allocation for contractor. The research was conducted to compare the cost risk of the three tipes of contract according to contractors experiences. The result from the cost risk comparison will expected to give alternative for contractor and owner in taking decision among lump sum, mixed and unit price contract.  The investigation was held by spreading questionnaires. There were two stages surveis to 35 contractors as respondents in Bireuen District. The first stage was held to find the risk events ranking and the second stage was to find the rating of the comparison to risk events. Then, the collected data was processed and analyzed by using Analytical Hierarchy Process (AHP) method. According to first questionnaires result, it was obtained 6 risk events that assumed dominant which could effect the cost construction overrun; there were the market price increasing, design revision, scope of construction revision, the difference of construction site between in the location and contract, not timely payment and material specification change. By using AHP method,  the risk comparison according to type of contract which is related with cost aspect, it can concluded from global priority value; the lumpsum was 0.485 , then mixed contract 0.285 and unit price contract 0.230. So the lump sump contract had the higher risk  than unit price contract.Keywords : Cost risk, contract, lump sump, unit price, AHPAbstrak: Bentuk kontrak konstruksi yang dikenal di Indonesia terdiri dari kontrak lumpsum, unit price dan gabungan keduanya. Setiap jenis kontrak memiliki risiko yang berbeda bagi kontraktor. Penelitian ini bertujuan untuk membandingkan risiko biaya dari ketiga jenis kontrak menurut pengalaman kontraktor. Hasil dari perbandingan tersebut diharapkan dapat memberikan masukan bagi kontraktor dan owner dalam pengambilan keputusan antara kontrak lumpsum, gabungan  dan unit price. Penelitian dilakukan dengan menyebarkan kuisioner yang dibagi dalam dua tahap terhadap 35 kontraktor di Kabupaten Bireuen sebagai responden. Tahap pertama untuk mendapatkan perangkingan peristiwa risiko dan tahap kedua untuk mendapatkan penilaian perbandingan terhadap peristiwa risiko. Data yang didapat kemudian diolah dan dianalisis dengan menggunakan metode Analytical Hierarchy Process (AHP). Berdasarkan hasil kuisioner tahap pertama didapat 6 peristiwa risiko yang dianggap dominan yang menyebabkan pembengkakan biaya pelaksanaan proyek yaitu kenaikan harga pasar, perubahan desain, perubahan ruang lingkup pekerjaan, adanya perbedaan site lapangan dengan yang tercantum dalam kontrak, pembayaran yang tidak tepat waktu dan perubahan spesifikasi material. Dengan menggunakan metode AHP maka perbandingan risiko berdasarkan jenis kontrak yang berkaitan dengan aspek biaya diperoleh bahwa proyek dengan kontrak lumpsum akan lebih tinggi risikonya menderita kerugian dibanding kontrak unit price. Ini dapat dilihat dari nilai prioritas global yaitu  0,485 dibanding dengan kontrak gabungan 0,285 dan kontrak unit price 0,23. Dengan demikian kontrak lumpsum lebih berisiko dibandingkan dengan kontrak unit price.Kata kunci : Risiko biaya,kontrak, lumpsum, unit price, AHP.
