Abstract

The BRI Medan Tower Building is a multi-storey building consisting of 12 floors and 2 basements, so that in planning the structure it must be designed to be strong and safe enough to withstand the load carried and withstand external influences on the structure. Previously, the BRI Medan Tower Building was a building with old design standards. Thus, this thesis aims to evaluate the design of beam structures in existing buildings based on SNI 2847:2013 concerning Requirements for Structural Concrete for Buildings. The method used is the beam analysis method using SNI 2847:2013. From the analysis results, it is found that the evaluation of beam analysis calculations obtained with the results in the field is the same. The installed compression reinforcement has not yielded so that the beam cross section is a tension controlled section. The flexural reinforcement distance in the beam is D10-200. The results of the evaluation of the beam analysis calculation obtained the amount of tensile reinforcement 14D25 and 4D25 and compression reinforcement 12D25 has been able to carry the load on the beam, so it can be concluded that the results of the planning have met the applicable requirements. SNI 2847:2013 can be used for planning reinforced concrete structures because the results obtained at the time of planning with the results in the field are the same.

Abstract

Soil with unfavorable characteristics often creates new problems, one of which is soft clay. Therefore, a soil improvement method is needed to change the characteristics of the soil. Two-stage stabilization using bukho rock ash and volcanic ash has the potential to overcome this problem. Based on the results of the study, the optimum CBR value was 9.245% from two-stage stabilization of soft clay soils with 12% bukho rock ash and 4% volcanic ash added. The addition of 6% bukho rock ash and 4% volcanic ash obtained 100% soil density. The addition of 9% bukho rock ash and 4% volcanic ash obtained 100% soil density. The addition of 12% bukho rock ash and 4% volcanic ash obtained 100% soil density. This shows that the effect of two-stage stabilization based on percentage variations can increase soil density.

Abstract

The Kerasaan irrigation area is an irrigation area located in Pematang Bandar District, Simalungun Regency, North Sumatra Province. With a functional area of ​​5000 (Ha) and a primary irrigation channel area of ​​31.02 (km). In optimizing irrigation performance in the Kerasaan irrigation area, maintenance of the irrigation network infrastructure must be carried out, one of which is by evaluating the irrigation channels in the area. This evaluation aims to identify and analyze the condition and function of irrigation assets in the Kerasaan irrigation area, so as to optimize the function of the irrigation canal to irrigate the lands in the irrigation area. The method used in evaluating the irrigation canal is the observation of method by tracing the irrigation network using a tool (GPS) to find out the coordinates of the channel point and documenting asset damage with a camera/mobile phone. Based on the results of the analysis, the total length of damage to the channel structure of the pair is 10 m from a combination of several segments in 2 canals in the primary channel with a total damage index of 0.70%. In the Kerasaan primary channel from the survey results as far as (± 1500 m) in the field, there are 1 unit of side spillway building, 2 units for tapping, and 2 units of mud bag building. The results of the analysis can be used for planning the construction of irrigation buildings by planning structures, sluice gates and measuring buildings.

Abstract

In 1999, the Department of Regional Development issued a specification regarding the Guidelines of planning mixed hot asphalt with absolute density apporach (Pedoman Perencanaan Campuran beraspal Panas dengan Pendekatan Kepadatan Mutlak). One of the specifications issued is Asphalt Concrete – Wearing Course (AC – WC) as the second layers in tiers of different types of asphalt concrete is the topmost layer in the roughness supple. Generally, asphalt is used as a binder, in a mix of this AC – WC uses LLDPE 5% and 7% as a substitute of most asphalt, in order to increase the value of its stability, as well as one of the concrete steps as handling reductiong waste that is difficult to unravel with the increase in the value of the function. Stages of asphalt mixture with LLDPE as a substitute of most asphalt include testing asphalt, Fine Aggregate, Coarse Aggregate and Filler Testing in order to find out its characteristic against Marshall Test. The highest percentage in the early immersion is owned by a mixture with pure sample levels, then followed by the addition of 5% and 7% of LLDPE in lieu of most asphalt. The results of testing gravity on the aggregate of split stone is 2.576gr/cc. Levels of asphalt plan which will be used for pure sample is 6.25% of total mixture, followed by 6.25 with a mixture of 5% LLDPE and 6.25 mixed with 7% LLDPE. The results are 5% flow is 3,70, 7% LLDPE is 3.70%, the stability of 5% and 7% LLDPE are 924 kg/cm2 and 735kg/cm2 , and Marshall Quotient 5% and 7% of the linear low density poly ehylene is 255.00 kg and 200,00 kg.

Abstract

Organic soils pose many obstacles to the construction that will be built on it and are generally caused by physical properties of organic soils which have very high water content and low carrying capacity. The physical properties of a material will greatly affect the mechanical properties of the material as well as the organic soil. The mechanical properties of organic soils are very low, for example the value of free compressive strength (UCT). One method to increase the carrying capacity of the soil is by adding or mixing with materials that have a high soil carrying capacity. Adding lime to the sample in this study is expected to increase the carrying capacity of organic soil against free compressive strength (UCT). Then the sample is given the addition of lime with an additional percentage of 2%, 4%, 6%, 8%, 10% to see the comparison of the value of compressive strength (qu), after the addition of lime. The results of free compressive strength testing showed soil behavior in a sample condition with the addition of lime up to 10% experienced an increase in qu. The more the mixture of lime in the soil sample, the greater the value of free compressive strength (qu). In the original soil the value of free compressive strength (qu) was 0.837 kg / cm2, the soil was remoulded at 0.886 kg / cm2, and the free compressive strength (qu) at the addition of lime 10% was 1.132 kg / cm2.
