Abstract

The sun is a source of alternative energy that is not polluting and can be used either directly or indirectly. Based on that we can use the energy of sunlight to heat water system with thermosiphon effects, by using a means of collecting solar radiation (solar collector) which absorbs the radiation and convert into heat through the absorber plate and forwarded to a pipe containing water. Absorber plate layer affects the effectiveness of the absorption of solar heat collectors. Solar collector is analyzed in the variation of the absorber plate layer on the parallel pipe, absorber plate is positioned above and below the parallel pipeline. Experiment conducted starting at 9:00 am to 15:00 pm. Effectiveness of heat absorption is obtained by using a layer under the parallel pipe plate at 11.2%, while for the layers above and below the plate parallel pipelines reached 17.8%. Differences in the efficiency of the obtained results that the use of layers above and below the absorber plate parallel pipeline more effectively.

Abstract

Vehicle for pengakut goods such as trucks, have tended to point loading up backward toward the center of the body. The back of the truck so the suspension will experience a greater deflection than the suspension on the front. Truck rear suspension system uses leaf springs, which will undergo the toughest conditions in the compressive load over and over again, so the potential for failure due to material fatigue limit passing.In this research investigation into the leaf springs on trucks carrying sand in the form of a broken failure. A broken spring release of a series of truck suspension system to cut the rupture area and certain areas that want to be observed as a test specimen.

Abstract

Clay soil is a soil type which has a low bearing capacity so that it will face problems if the clay is receiving considerable expense. One alternative to improve the bearing capacity of clay soil is to provide a ditusukan cerucuk into it. This study aimed to discover how much influence cerucuk use of soft clay soil strength.The method used is by the addition of wood with a diameter pole cerucuk ± 8 cm in the soft clay which then will be tested with a shear tester (Vane Shear Test) with the length and spacing cerucuk cerucuk varied.The results after cerucuk anchored into the clay soil showed an increase in shear strength of clay soil, compared with a shear strength values without cerucuk. For 60 cm long with a space cerucuk 2D, 3D, 5D, respectively 5.25%, 2.20%, 1.06%. For 80 cm long with a space cerucuk 2D, 3D, 5D, respectively for 25.15%, 20.73%, 18.91%. For cerucuk 100 cm long with a spacing of 2D, 3D, 5D, respectively for 33.80%, 31.63%, 29.93%. With this we can conclude that the longer the cerucuk and the closer the distance between cerucuk, the more can increase the shear strength of clay soil.

Abstract

Reduction of forests due to human needs has a negative impact on a watershed, one of the effects of the reduction of the forest is the occurrence of erosion and sedimentation on Kapur Kecil river . To determine the sedimentation rate used method of USLE (Universal Soil Loss Equation). USLE method considering the land use on study area, thus this method can be relied upon as an analysis of the amount of sedimentation. The results showed that the sedimentation that occurs based on USLE method of 0,13 mm/year and sedimentation volume of 8,517.65 m3/year.

Abstract

Based on the records of the Ministry of Public Works, the number of contractors in Indonesia reaches 180 thousand companies. This number tripled compared with companies in Chinese State. The large number of companies lead to unfair competition in the construction business so would be contrary to the principles of procurement: efficient, effective, transparent, open, competitive, fair/non-discriminatory, and accountable. This study aims to analyze disparities of bid prices to Owner’s Estimate (OE), case studies of public procurementwithin Pemerintah Kabupaten Kampar, specifically on road and bridge work packages.

Abstract

From the research that has been conducted on energy audits in buildings PT. X, to know the profile of energy use and energy savings opportunities, so it can be more efficient and save costs. From the initial energy audit have been implemented acquired Energy Consumption Intensity (IKE) to the total area is still under IKE standards for office buildings. For air-conditioned room is not air conditioned and acquired Energy Consumption Intensity (IKE) is low so as very efficient. By replacing energy-efficient appliances, then there is a chance of saving energy

Abstract

Corrosion is a problem that always happens to the equipment of oil and gas production. Pipe production is one piece of equipment that will not be separated from the process of corrosion. Long Range Ultrasonic Testing is one method that can be used to detect the onset of corrosion in the production pipeline. The method makes use of ultrasonic waves as a medium in the complete evaluation by teletest unit as system settings. In the test series in the field of production pipe Arzon # 89 the corrosion rate will be obtained when the magnitude of the reduction is calculated first pipe wall thickness (wall loss) of yield teletest data reporting system.

Abstract

Generally the condition of roads at transmigration area in Rokan Hulu is still not on the asphalt, which indirectly this will affect accessibility to this area. This thing will make problems for road users, particularly related to vehicle operating cost.In this study, the researcher create a model of vehicle operating costs, especially for trucks. Where the vehicle is used by local residents for transporting farm crops in this area is to be brought to the factory. This model is influenced by the independent variable speed trucks.From the results obtained by the analysis of vehicle operating cost model trucks: fuel consumption model Y = 7,68E-6 V3 – 0,001 V2 + 0,032 V – 1,35 with R2 = 0.728 and the value of F = 5.361, lubricating oil consumption model Y = 4,62E-7 V3 – 5,6E-5 V2 + 0,002 V – 0,12 with R2 = 0.689 and the value of F = 4.431 and tire usage model Y = 5.46E-7 V + 9.72E-5 with a value of R2 value = 0.423 and F = 5.876
