Abstract

Flash flood is a process flow of heavy water and massive load concentrated is accompanied, also rock chunks, soil and logs (debris) from the upstream. Flash flood’s triggered by climatology and geological factors, landslides and natural damming at the upstream. The rising of water discharge flood process occurs suddenly and rapidly. The research in the Lawe Liang Pangi Watershed, Leuser Sub-district, Southeast Aceh Regency. Based on information, there are heavy rains occurred during the 3 days before the flood. Flooding occurred on Friday evening, August 17, 2012 at 22:00. Occured landslide at 15 locations. The most substantial damage is Naga Timbul, Suka Damae, Sepakat, Gaya Sendah, Punce Nali, and Bun-bun Indah villages. Liang Lawe Pangi watershed topography is mountainous, moderate to steep slope. The soil type is a little fine sandy silt loam and dark brown, and the soil type is erosion susceptible. The river bank stability test results for the two sampling locations, the safety factor in extreme conditions (flooding) is smaller (1,34) than the standard value (1,50). The flood conditions (inundation) is not secure against river bank scour. It is certainly more dangerous when taken by flash floods at a large velocity and followed by massive load. Recommendations for prevention and  mitigation of flash flood disasters in Leuser Sub-district, the disaster prevention and mitigation in the structural measures that to typical flood prone locations and non-structural measures including vegetation and public education work for the land management.

Abstract

A clay-silty located in the quarry Meunasah Rayeuk, Kaway XVI, West Aceh is a source of stockpile material that is often used as road construction material in West Aceh. Based on the color this land is divided into three, namely red, yellow, and gray soil. These three types of soil have bad properties that make them unfit for use as road base layers. Therefore, it is necessary to stabilize it with a mixture of volcanic ash taken from Wih Pesam, Bener Meriah. The purpose of this study was to determine the effect of mixing soil with volcanic ash on the shear strength of the soil. This research method was carried out in the form of standard compaction tests, and direct shear strength on mixed volcanic ash soils. Variations in the addition of volcanic ash are 12.5%, 15%, 17.5%, and 20% of the dry weight of the soil. The research results show that these types of soil belonged to the A-7-6 of soil classification according to AASHTO identified as containing montmorillonite minerals in gray soil. The addition of volcanic ash to the three types of soil can increase the value of the shear strength of the original conditions at certain variations. The results of shear strength values ​​for volcanic ash mixture variations of 0%, 12.5%, 15%, 17.5% and 20%, were 0,8, 1,0, 0,8, 1,0, and 0,7 in units of kg/cm2 for red soil respectively. In the yellow soil of 1,0, 1,0, 0,9, 1,2, and 0,9 in units of kg/cm2. On gray soil as much as 0,7, 1,1, 1,0, 0,9, and 1,1 in units of kg/cm2.

Abstract

Banyak metode yang dapat digunakan untuk perhitungan daya dukung pondasi. Setiap metode dengan asumsi yang berbeda-beda cenderung menghasilkan besaran daya dukung yang berbeda. Tujuan penelitian untuk mengetahui daya dukung pondasi bored pile pada JOP pembangunan jalan tol Sigli-Banda Aceh menggunakanan data N-SPT dan mengetahui metode mana yang mendekati hasil aktual uji PDA sebagai kontrol kapasitas dukung tiang. Analisis daya dukung pondasi menggunakan metode Meyerhoff, Luciano Decourt dan Sosrodarsono. Pada titik BH-6/tiang No.4 A4 hasil daya dukung yang mendekati hasil aktual uji PDA diperoleh dengan metode Meyerhoff sebesar 910,6 ton. Titik BH-7/tiang No.6 P1 metode Meyerhoff dengan Qult sebesar 1001,6 ton mendekati hasil daya dukung aktual uji PDA. Pada BH-8/tiang No.1 A1 hasil daya dukung dengan metode Sosrodarsono mendekati hasil aktual uji PDA yaitu sebesar 1111,8 ton.
