Abstract

Rivers are the best sites to observe the natural effects of sediment transport. Phenomenon of sediment transport in the flow was much scrutinized by experts and some sediment transport equations have been developed. But the performance of these equations is still controversial. Gomez and Church (1989) evaluated a number of sediment transport equations were developed for flows with a gravel base and find that none who have a good consistent performance. This paper examined the sediment transport with a case study on Krasak river in Yogyakarta. This paper intended to test the accuracy of the count by using a dimensionless sediment transport equations of Einstein (1950) on sediment transport measurements. Based on the relationship between the flow parameters (?) and the transport parameter (?) of this study compared to the graph of Einstein (1950), it appeared that some of the research data plot was fairly spread. In the plot of data with ? = 2.00 to 4.00, the trend of the data deviated far enough above the curve of Einstein. In the plot of data with ? = 1.35 to 2.00 and ? = 4.00 to 5.00; trends in the data were slightly above the curve of Einstein. While the data with ? = 1.06 to 1.35 trends to follow the curve of Einstein. This last data has a coefficient ? closed to uniform.

Abstract

The response structure due to dynamic load or earthquake in a building is very important to be know.Therefore we tried to do some research with make a model that can show the behavior of structure when receives the dynamic load. In this research the structure is modeled with two-dimensional discrete system with a system of beams and columns of the same strength, it is easier to see the behavior of structure. The system is made by Power Fortran language program Station. The methods used for solve structural vibration dynamical equations is the Runge-Kutta order 4. The results shown in graphical form with the help of MS Excel program. From the graph shows that the pattern of responses produced is same with a given load pattern but have different intensity and deviation. Beside that , the structure will receives displacement, velocity, and acceleration are greater when receiving a load that is not harmonious with the same frequency. This suggests that the structure would be more resistant to a greater load if given regularly, compared with the sudden load.

Abstract

Construction and its concrete scaffolding is a temporary construction (construction support in concrete construction), due to the cost required is quite large, approximately 1/3 of the total cost of the concrete construction, it is based on the analysis of unit price work (SNI 03-7394-2008), therefore it needs to be examined in order to reduce the cost of its construction and for the cost efficiency in the construction of storey buildings. This research conducted assessments of the selection of scaffold materials for the manufacture of concrete construction, the objective is to select the best type of scaffold material thus it would be able to reduce the cost of the buildings construction. By using the method of Analytic Hierarchy Process (AHP), the assessment was conducted on the three alternative types of scaffold materials of concrete, these materials were the bamboo, the wood, and the iron / pipe galvasnis (scaffolding). The result of the calculation by the alternative assesment, is that the higher rank is the scaffolding which is 0,531, while the bamboois in the second with the total score 0,301 and the wood is the lowest with the total score 0,168. It can be assumed that the result of this research on the basis of five criteria, namely: the cost; the strenght and the durability;the effectiveness of the instalation and dismantling; the security and the safety work, as well as its impact on the invironment that the scaffolding is the best alternative chioce of the materials.

Abstract

Sika-215 Grout is ready grouting material that has multiple features have expanded properties and very easy in use, that is just simply add water with a specific ratio. Many application are already using this material for purposing of anchorage bolts, precast concrete connections, but more broadly-215 sika grout can be used for machine foundations, column base plates, foundation support a bridge, and so on. The purpose of this study to determine how many influence the shape and length of anchorage against strong pull between the anchor-reinforced concrete grout Sika 2l5. Specimens in this study a concrete cube 15x15x15 cm 2 for the strong pull and testing of concrete cylinders with a diameter of 15cm, a height of 30 cm for the characteristic compressive strength testing, the concrete mix design based on the K-225 at 28 days, while the iron anchor used is concrete screw diameter of 16 mm. The results showed that the long form of anchor and anchoring to the real effect of the strong pull Out force is generated. With a surface area of 225 cm2 test piece, grout Sika grouting material 215 provides a powerful pull an average of 6834 ton maximum length that occurs in the form of anchoring 14cm straight (type-a, and 6 cm diameter hole grouting.

Abstract

Construction failure is not uncommon as the construction industry is very complex, where many parties involved and processes take place in an open space. The construction failure and the building failure might be caused by either the technical or non-technical factors. The non-technical factors mostly derive from the lack of resources competence in the business entities, the employee skill, and the expertise. This paper discusses the mutual relationship between the SBU (Business Entity Competence), the SKA and the SKT (Man power Competence), and the Construction failure. This research is conducted to analyse the construction failure from the perspective of the resources competence with regard to specially the SBU, the SKA, the SKT, where as the aims of this research is to indentify the non-technical factors causing the construction failure and the building failure in Central of Jawa, and also to analyse the contributions of the SBU and the SKA and the SKT toward the Construction failure. The factors that influence the failure was measured in the qualitative model and simulated with the LPS method using the causal relationship approaches between the variables supported by the TETRAD program IV vertion 4.3.9-18. The result of the research reveals that the failure variable are structurally affected by the SBU variable 0,1181, by the SKT variable at 0,0501, and by the SKT for 0,0250. The test processes of the SBU, the SKA, and the SKT has not been implemented properly so that the certificates issue can not yet be justified. The resource conditions in the district and the city around the project area are still troublesome, such as lack of the man power having the SKT, and the SKT, and there are many skilled workers that have not got the competence test.

Abstract

A very influential factor in the development of cities in Indonesia are natural population growth and migration from rural to urban areas. The increase in population led to the need for housing is also being increased. The rice fields and hills farm lot converted into residential complexes. Changes in land use is a major cause floods and landslides. The loads addition in body the slopes by making residential building or villa on the edge of a slope or on a hilltop is a effect risky action landslides. From result testing soil housing in Bukit Mutiara Jaya II, the carrying capacity of the land base is still able to support the weight of the building, namely: QB = 0.217 kg / cm2 <Qall = 0.285 kg/cm2 (still safe). On the case of residential Bukit Mutiara Jaya II decreased and the slope of the walls and cracks in some buildings in the residential location, not because of low soil bearing capacity but due to technical error implementation, it is also prone to landslides because the soil in the form of land use in paving pile above the original ground sloped slopes between 15-40%, which is not compacted properly functioned converted into a dwelling or housing. Where land in a pile on the surface of the slope be spread out natural land directly used for the placement of the building foundation besides causing land subsidence and landslides when it rains, it is also due to the spread of the load is not evenly distributed and downs of the carrying capacity of the land caused by decreased physical and mechanical properties due to the presence of water in the soil body slope..
