Abstract

The downpour in most of Taman Nasional Bukit Barisan Selatan (TNBBS) Lampung areas caused landslide on a cliff in Liwa – Simpang Gunung Kemala STA.263+650 roadside so that a part of the roadside covered by the landslide. For this case, it takes slope stability analysis to determine safety factors of the slope in research site that can figuring accordance with the real conditions on the field in order to enable the approaches condition on the result of analysis and to simplify the process of figuring the handling, one of them is through the using of manual formulas and Plaxis program. The result of this research shows that soil parameters greatly affect the stability of slope. Partially saturated slope condition has the smallest stability compared to other conditions. Based on the analysis conducted before handling condition, it is acquired the deformed mesh = 885x10-3 m; ac- tive pore pressures = -168.89 m; effective stress = -535.76 kN / m2; safety factor = 0.2847. On the condition after handling, it is obtained values of deformed mesh = 818x10-3 m; active pore pres- sures = -132.36 m; effective stress = -209.77 kN / m2; safety factor = 1.3548.

Abstract

Paving blocks made from mixture of portland cement or other hydrolysis adhesive, water, and ag- gregates with or without other materials. In this study, paving blocks are made by using a mixture of soil, portland cement and sand. In the manufacture of paving blocks used compactor modifica- tion that are expected to increase the strength of paving blocks that according to SNI 03-0691- 1996. Soil samples tested were from Kota Baru, South Lampung. The variation of mixture that used in this study is by adding sand as much as 2%, 4%, 6%, 8%, and 10% and add cement as much as 3%, 6%, 9%, 12%, dan 15% as well as with the treatment of pre-combustion and post- combustion of the sample of paving blocks. Results of testing the compressive strength of the paving blocks with a mixture of soil , cement and sand has meet the standard of SNI 03-0691-1996 for the classification of paving blocks quality D which can be used for garden. The combustion process of paving blocks is giving only slightly against the increase in paving blocks without the process of combustion. The highest compressive strength value generated by post-combustion of paving blocks on the variation of mixture 10 % sand + 15 % cement + 75 % soil amounted to 10.05 MPa . While the value of the water absorp- tion test ranged from 16.6 % - 23.8 % so it does not meet the standard of SNI 03-0691-1996 .

Abstract

The tested soil sample in this research is sandy clay soil. The variations of procentage are 5%,10%, 15%, and 20%. Each of samples are cured in 14 days. Based on the physical soil propertiesinvestigation, AASHTO classified the soil sample into A-2-6 group (sandy clay soil), while USCSclassified the soil sample as soil with rough granules into SC group.The results of the research in the laboratory showed that the additive material using Merapi vol -canic ash could improve the physical and mechanical properties of organic clay soil. In the physi-cal test such as unit weight and Atterberg limit tests, the values decreased after it, while the me-chanical test of Merapi ash sample showed it could improve the value of unconfined compressionstrength soil. Based on the result of unconfined compression stregth test, soil which is stabilizedusing the ash of Mount Merapi increase until the optimum ash content about 20%.

Abstract

Soil is a material that serves as an support for the basis of a constuction, be it construction of buildings, bridges and roads. Each region has different soil characteristics in other regions, there is high and has a bearing capacity of those that are low. To improve the soil characteristics that can lead to low bearing capacity, the necessary repairs to soil stabilization methods. Stabilization efforts are often undertaken by stabilizing additives. In this research using a chemical additive material that is TX-300, which is expected to improve the characteristics of the soil so the soil is worthy of a construction established. Soil samples that tested in this research is the soft clay are derived from Rawa Sragi, East Lampung. This study used soil mixed with ash content about 0,9 ml with the optimum variation of curing time used is 7 days, 14 days and 28 days. Based on the test of physical properties of original soil, AASHTO classifies soil samples in group A-7 (clay soil) and subgroup A-7-5, while the USCS classifies soil samples as fine-grained soil and belonging to CH group. The results of laboratory studies indicate that the stabilization material using TX-300 can improve the physical and mechanical properties of soft clay. The soil that has been stabilized with TX 300 has increased the value of specific gravity and bearing capacity and it is decreased of liquid limit and indeks plastisity of soft clay. Based on the test results, this type of clay is not too good to be used as a ground subgrade for road construction, because its PI’s value is about ≥ 10% despite value of CBR is plenty high.
