Abstract

Disaster mitigation due to seismic load (earthquake) needs to be considered. This is especially for dam structure used as a reservoir and water resource. Because of the main function, and building dimension is too large, thus if the dam collapse it will cause a significant catastrophe for the surrounding community and environment. One of the seismic damages to the dam is deformation. This paper presents the effect of seismic load on deformation of dam model simulation. This study took place on the Sermo Dam, Yogyakarta which is located close to Opak Fault –as the suspicious cause of the earthquake in Yogyakarta. Seismic loads used in this study in terms of acceleration time histories. Therefore model can be carried out using PLAXIS simulation. This selected seismic load variations are on the range 5.0-7.0 Mw and epicentrum distance is also restricted in 15-31 Km based on the nearest epicentrum distance between Sermo Dam and Opak Fault. Keywords: seismic load, deformation, dam, modeling

Abstract

In the construction project implementation, the contract is a bond between the project owner as the service user and the implementer / contractor as the service provider. The contract outlines the forms of cooperation, whether technical, commercial, or legal in a clear and detailed way. A fair contract should balance the rights and obligations between the two parties. So both parties should look at the articles in the contract so that the things that pose risks can be avoided. In the project implementation, the usual contracts are Lumpsum contract and Unit Price contract. The method used is Analytic Hierarchy Process (AHP) Method. The analysis process begins by defining the problem, and creating a hierarchical structure. This hierarchy consists of 3 (three) levels of objectives (level I), criteria (level II), and alternative (level III). Based on the hierarchy and then compiled questionnaires, Questionnaires were distributed to 71 respondents consisting of contractors in Semarang. The data obtained are then tabulated, followed by pairing matrices, pairing comparisons, measuring priority weights for level II and level III, and checking for consistency. This means that projects with lumpsum contracts are at higher risk of losses compared to unit price contracts. The Based on the result of cost swelling risk analysis, we get the priority weight for lumpsum contract equal to ≥50% and contract unit price ≤50%. Keywords: Risk, Methank, Analytic Hierarchy Process (AHP).

Abstract

In Buton Island, an island located in South-East Sulawesi Island in Indonesia is found about 700 million tons natural rock asphalt (NRA) which have not been maximally utilized yet. Buton-NRA contains 20 to 30% of bitumen. This paper reported the experimental study on utilizing of Buton-NRA as additive of bitumen binder in hot mix asphalt (HMA) mixtures. Amount of 5, 10, 15, 20, 25% of very fine of Buton-NRA was added into the bitumen, resulted Buton-NRA-Bitumen’s binder. Penetration and softening point test were conducted to get penetration index (PI) value, an index to determine the temperature susceptibility of the binder. The results show that the Buton-NRA-Bitumen’s binder has low temperature susceptibility. Used as binder in HMA mixtures also shown that the Buton-NRA-Bitumen’s binder can improve the performance of the mixtures. Marshall Stability and stiffness of the mixtures are higher compared to that of base bitumen binder, especially Buton-NRA-Bitumen’s binder with 15% of Buton-NRA, Marshall Stability reaches 1620kg and stiffness 142kg/mm, while HMA mixtures with base bitumen (0% Buton-NRA) only has 1068kg of Marshall stability and 110kg/mm of stiffness. Keywords: Buton-Natural Rock Asphalt, Binder, Improve, Performance, HMA mixtures.

Abstract

Pipes laying on an unstable slope of soft soil are prone to movement. Pipelines that are buried in unstable slope areas will move due to lateral loads from soil movement which can cause damage to the pipeline. A laboratory small-scale model of the reinforcement system of piles supported retaining walls was conducted to investigate the effect of lateral load on the reinforcement. In this experiment, the lateral forces of 0.3 kN, 0.35 kN, and 0.4 kN and vertical force of 0.05 kN, 0.1 kN, and 0.15 kN were used. Lateral load from electric jack is equipped with load cell and vertical load used cement- steel box. To validate the experimental result, a finite element program was used. The experimental results showed that an increase in lateral loading, increased the displacement of the reinforcement system. For a Vertical Load 0.05 kN and versus a lateral load of 0.3 kN causes a horizontal displacement of 0.34 mm and an increased of 2.94 % for loading of 0.35 kN and an increased of 8.82% for loading 0.4 kN. The pattern is the same in the finite element method analysis, where there was a 2.3 8% increased for 0.35 kN loading and an increased to 33.33 % for 0.4 kN loading. In the same Load, the Reinforcement System is reliable as shown in Safety Factor on dry condition were 3,33, 2,828 and 2,476, and on wet condition were 2,99, 2,524 and 2,237.
