Abstract

The finite element method is a method of modelling of an object to divide into smaller parts as awhole still has the same properties as the whole thing before it was divides into smaller sections(discretization). The finite element method can be used to analyse various types of structures, suchas plane truss, space truss, plane frame, space frame, beam, and grid.The main difference space truss and space truss are the number of degrees of freedom at eachnode. Each bar in order to space has six degrees of freedom. A space truss structure formed by thecombination of elements order in XYZ space. Variations of incorporation requires thetransformation of the characteristic elements of the local coordinate system to the globalcoordinate system.In this study, analysis of space truss using the finite element method will be assisted with thesoftware Matlab. Where the result of Matlab will be compared with result from the SAP2000. Theresults of this analysis are joint displacement, joint reaction, and element forces.Keywords : Finite Element Method, Space Truss, Matlab

Abstract

Paving blocks are widely used as a public building construction, especially for paving roads,yards, sidewalks, parking lots, etc. The use of materials such as paving block the main constituentof cement and sand is relatively expensive. So in this study will provide another alternative tousing a mixture of soil and lime.Soil samples tested were from Kota Baru, South Lampung, with variations in the levels of themixture used is 0%, 5%, 10%, 15%, and 20% and the curing time for 14 days, as well as with thetreatment without burning and burning which will then be tested compressive strength and waterabsorption.The results showed that the compressive strength occurs at the most optimal mix of 15% and adecline in a mixture of 20%. The addition of lime percentage ≤15% resulted in the addition ofcompressive strength of paving blocks, while the addition of lime percentage of 20% resulted in adecrease in the compressive strength of the paving blocks. The compressive strength withoutburning still not meet the specifications of SNI 03-0691-1996, while paving blocks with burningthe lime content of 15% is already included in the classification of the quality of D. Waterabsorption test values not meet the specifications of paving blocks SNI 03-0691-1996 whichranges from 3%-10%.Keywords : Paving block, kapur, kuat tekan, daya serap air

Abstract

Jepara watershed is part of the watershed is located in East Lampung district with an area of 10km 2 , where Jepara River is one of river flowing into Lake Jepara. Jepara River conditions at thistime had a reduction in the flow of flood discharge due to reduced cross-sectional area of the riverdue to sedimentation. The main cause of the high rate of sedimentation is the destrusction of watercatchment areas and land management less attention to the principles of conservation land.Therefore it is very necessary management effective river drainage area with emphasis on theconservation and protection of the land and water, especially in the upper reaches of the river.One of the measures for erosion and sedimentastion problem in this river is by building sedimentcontrol structures or so-called check dams.From the calculations have been done check dam is planned to have the following physical;lighthouse spillway crest elevation checkerboard on +35,915 m elevation with an effective heightof 3 m and a depth of 2,5 m foundation,wide spillway lighthouse checkerboard obtained by 40 m,Q design with a return period of 50 years at 119,9113 m3/sec, high wing checkerboard of 2,007 min elevation +39,622 with a height of 0,6 m surveillance, construction of the main dam is aconcrete construstion, lighthouse spillway crest elevation of the sub dam +33,915 m with a heigtof 1 m and a lighthouse foundation depth of 1,2 m, a high wing sub dam at 1,9 m an elevation of +34,4251 m with a height of 1,0 m surveillance, construction of the sub dam is a concreteconstrustion,the elevation of the floor protected at +32,915 m elevation with a thickness of 0,5 m,the construction of a concrete construstion.Keywords : Jepara River, erosion, sedimentation, checkdam
