Abstract

There is still a lot of casting concrete implementation which is mixing location was far with the casting location, because the situation in the field there are many obstacles to implement it.  As a result, from the mixing place to a casting place take a long time, so long as transportation there is a process of hydration in the concrete, which can cause a decrease in the quality of the concrete. To determine the decreasing of concrete quality, the research conducted is to determine the effect of time between when the mixing process of the concrete to casting process. This study used 48 specimens were divided into two groups, namely 24 specimens using the time difference without rotation and 24 pieces again with rotation. Each specimen using the same water cement ratio (fas), namely 0.45. Each group was subdivided in 6 variations in the time between mixing and casting namely :. 0 minutes, 12 minutes, 24 minutes, 36 minutes, 48 minutes and 60 minutes witch each variation using 4 specimens. The result of compressive strength each specimen group, for group I (without rotation) is 348 kg / cm2 for 0 minutes, 342 kg / cm2 for 12 minutes, 333 kg / cm2 for 24 minutes, 322 kg / cm2 for 36 minutes, 310 kg / cm2 for 48 minutes, and 294 kg / cm2 for 60 minutes. For group II (with rotation) is: 338 kg / cm2 for 0 minutes, 336 kg / cm2 for 12 minutes, 333 kg / cm2 for 24 minutes, 329 kg / cm2 for 36 minutes, 324 kg / cm2 for 48 minutes , and 318 kg / cm2 for 60 minutes. The results showed that, for the concrete without rotation: compressive strength at 60-minute time delay decreased by 15.52% of normal concrete (0 minute delay), and to the mixing concrete with rotation, compressive strength on delay of 60 minutes decreased by 5.92 % of normal concrete (0 minute delay). These results indicate that the delay time without rotation the greater the loss quality of concrete.

Abstract

Shipyard industry  is one of the most  important chain  on the national shipping system. Notably to maintains the vessels condition in order to get adjustment of The Indonesia Classification Bureaustandard. Shipyard’s productivity depends on the graving dock capacity, man productivity and work method. Empirical studies show that man competiveness and productivity and effective work method are primary factors which affects choice rate from shipping companies to a shipyard. The research goal was to analyzed the effect of man productivity and work method toward graving dock performance in PT. Janata Marina Indah Semarang. Multiple linear  regression used as a method in this research. Methodology use basic is difficulty to identify relating directly from man productivity and work method toward graving dock performance. The sampling method using  purposive random sampling with 35 respondents who have long experience in the graving dock works. The result of regression analysis is:  Y= -0,357 + 0,256 X1 + 0,249 X2. The result shows that two factors both man productivity and work method, are have  significant effect toward graving dock performance.

Abstract

Truss structure which is often used for primary girder  of bridge of highway is a Warren or Pratt  type, what is its use combined with two horizontal truss attached below and above functioning as truss of wind bracing. Though have space dimension, but its structure is not pure of truss space, practically its analysis is done to each truss, vertical and horizontal which is considered as plane truss.  Truss structure with a trianggular  cross section type represent other alternative from structure truss which can is also used as a highway bridge structure, and this type truss represent purification truss space. Beside that, structurally entire element truss together have the contribution to arrest forced from all direction, and cause this type truss is more stable in arrest torsion and shear compared to a other structure truss bridge type. Method used to analyse structure of truss that is stiffness matrix method by means of  assist calculation of Microsoft Excel 2007. Result to be reached from this analysis is to find relation of between span length, depth of truss and to the number of panel, to weight of structure and translation of a joint; utilize to get optimum weight and translation of joint. Pursuant to result analyse to three group of sample truss model, each group consisted of three sample, in each depth condition of certain truss, there's only one optimum weight value at one particular truss, and angle of inclination of diagonal and also the span-depth ratio and depth of  economic truss still stay in gyration of economic values is such as those which applied for plane truss

Abstract

The aim of the tests was to investigate the influence of cement on clay of Lampoh Keude Village Kuta Baroe district Aceh Besar district. Results to be seen is parameters of shear angle (ø) and cohesion (c) of the direct shear test. Normal stress to be given to direct shear test is 0.305 kg/ cm2, 0.634 kg  cm2 and 1.293 kg /cm2 with optimum moisture content obtained 23.15% and the dry volume weight 1.438 gr /cm2. This study tested three samples for each percentage mixture of 0%, 4%, 8%, 12% and 16% with one day curing period. The amount of specimen without cement mixture was made of 3 specimens and without cement mixture was made of 12 specimens for 3 repetitions testing. Soil testing in the lab include testing the physical properties of the native land, the mechanical properties of the native land and land with a cement mixture. Based on the testing  of the physical properties of the native land, AASHTO classifying soil in group A-7-6 (11) and USCS classifying soil as a silt and clay in CH group. The addition of cement shows the stability of direct shear tests with increases of  cohesion (c) and friction angle (ø) is 0% cement is c = 0.797 kg/cm2 and  ø = 31.45o, 4% cement is c = 1.326 kg/cm2, ø = 36,22o, 8% cement is c = 1.529 kg/cm2 and  ø = 38,55o, 12% cement is c= 1.950 kg/cm2, ø = 38,11o and 16% cement is c = 2.084 kg/cm2, ø = 39,01o. Direct shear test results by mixing cement on clay showed an increase cohesion (c) and friction angle (ø) parameters.

Abstract

Tide phenomenon that often occurs in the coastal areas of Indonesia resulted in flooding, which is called the tidal flood. A tidal flood overflow phenomenon of sea water inland. Often some of the roads located in coastal areas are flooded by tidal flood and often causing some damages to the road. Therefore it is necessary to investigate the effect caused by tidal inundation or water bath for asphalt pavement.This research aims to know the durability performance of asphalt concrete mixtures with marinade modification Marshall. The study was conducted with two standard methods of soaking in tidal water and laboratory. Water Immersion method is made by soaking continuous (continuous) and periodic (intermittent). Soaking the specimen in water tidal variation within 6 hours; 12 hours; 24 hours; 48 hours; and 72 hours. While the periodic immersion done by soaking the specimen for 12 hours, then removed during the next 12 hours during 3-days. To view the durability performance of asphalt concrete mixtures used indicator Index of Retained Stability (IRS), Stability Deformation Index, namely First Durability Index (IDP), and the Second Durability Index (IDK).The results showed that continuous immersion damage effects mix quicker on asphalt mixtures than regular immersion. Tidal water used to soak the asphalt mixture Hot Rolled Sheet-Wearing Course (HRS-WC) either continuous or periodic method, has a greater influence than the use of laboratory water. It is shown by the value of the durability of asphalt mixture soaked-tidal water smaller than water-soaked asphalt mixture laboratory standards.
