Abstract

Bottom of the river is always composed of a mixture of sediment in non uniform and the grain size distribution in the phase of the transported sediment is generally smoother than the distribution of basic material due to selective transport. This makes estimates of sediment transport in natural rivers is difficult; although it has provided the basic sediment transport equations are quite a lot, there is still controversy regarding its performance. This paper analyzes the accuracy of the count of the basic sediment transport using a dimensionless transport equations of Julien (2002), Brown (1950), Parker (1979), Engelund et Fredsoe (1976), Graf & Suszka (1987), Meyer-Peter & Mueller (1948), and Recking (2006) compared to Einstein (1950) formula. Methods discrepancy ratio (r) is used to demonstrate the suitability of the good (goodness of fit) between the results calculated for comparison. Based on the spread of the data on the graph of a diagonal line (line of perfect agreement) and on the basis of the percentage of data in the range of discrepancy ratio values are given, a matter of sediment transport parameters using the equations of Graf & Suszka give the most close to the matter of using the Einstein equation, compared with six other counts equation.

Abstract

Nowadays as the mobility of a person develop tends to require a shorter time, where time is a commodity that can’t be saved or stored so that time is very important to everyone. In this case the time value changes according to the level of income. When faced with two choices of Ring Road and Existing Road Ambarawa, person with high income levels tend to more appreciate the value of time by choose a route that has a value of time much more efficient. The aim of this study is to analyze the effect of the time value of road users traveling in the magnitude of Vehicle Operating Costs (VOC) for route selection on the Ring Road and Ambarawa Existing Road with Logit Binomial Model. The methodology of this research is to analyze the value of travel time Income Approach method is used, then to analyze the results of the calculation of the Vehicle Operating Costs (VOC) formula used PCI (Pacific Consultant International), and then to analyze the route selection with Logit Binomial Model. Results of the analysis can be concluded that the greater the time value of road users, then the probability of route selection-A also increased, due to the time value of road users with greater income, more important than the time value of road users with lower incomes.

Abstract

Concrete is a building material that is inexpensive and easily compacted or made, can meet their needs both in terms of strength and in terms of span length dimensions required. Advances in technology and the improvement of public welfare encourage residential development into a multi-storey building lots (flats) with reinforced concrete products. The rapid development of home stores, or so-called good-story office two (2) or (three) were not followed appropriate equipment for anticipated fire hazard. So sometimes when there is a fire and in addition to material losses also no casualties. Concrete is known material which is resistant to fire when it burns for a long time and high temperatures will be damaged (compressive strength is going down), certainly in reinforced concrete yuga will occur such things, besides the concrete was broken of course steel reinforced also damaged / decrease its tensile strength. Moreover, the reinforcing steel material is heat conducting material and when at certain high tempertures will melt and fuse so liquid. So that the structure of reinforced concrete as a building component when exposed to heat of fire with high temperatures and a long duration will decrease the tensile strength of steel reinforcement will bepengaruh on the stability of the building structure construction. As a result of the reinforced concrete structure with concrete cover thickness of 3 cm if burned by hot embers will decrease the strength of the quality of concrete K 175 if burned to 4 hours more will lose compressive strength of up to 52% and the loss of value of tensile strength in the reinforcing steel to 22%. This assessment is on post-burn conditions (specimen cold conditions). In the burn duration to 8 hours, the compressive strength of concrete K 175, a loss of power by 67% and the loss of tensile strength grades of reinforcing steel at 24.16% (specimen cold onditions or post-combustion testing).

Abstract

User-storey building in the activity from one floor to another floor of a multistory building need of vertical transportation (elevators). Elevator or lift is a vertical transportation used to transport people or goods. Elevators are generally used in the high rise buildings, typically more than three or four floors. Elevator specifications determined by the capacity, speed and carrying capacity. Selection is based on the use of elevators in the building people traffic, travel time back (round trip times), the peak time of use (peak-up times) and the waiting time in terms of capacity (handling capacity), the speed of the elevator. Adequate quantity for vertical transportation is an important factor, as it will affect the quality of service in a building, so we need a maintenance management that can manage performance elevators. Good elevator maintenance management includes periodic maintenance, checking the components, replacement of components that need to be replaced and the estimated cost of maintenance that is necessary to issue any annually building management. In Semarang city there are plenty of high rise office buildings, one of which is Perum Perhutani Unit I Central Java. The building has seven floors are used for the activities of the members. The method used in this research namely direct observation, primary and secondary data collection and data processing. From the results of data processing it can be concluded that the number of elevators in the building needs Perum Perhutani Unit I Central Java should totaling 3 units, while currently only available 2 units. In addition, the elevator maintenance management obtained regularly presented in the form of a checklist and budget maintenance costs as well as the replacement of some damaged components.Kata Kunci : elevator, kebutuhan, pemeliharaan

Abstract

The elevator is a vertical transport equipment that is used as a tool to facilitate the activities both human and goods to lead up particular floor in buildings. Moch. Ichsan building is one-storey building in Semarang that use elevator as transportation vertical lift. It needs effective and efficient elevator planning in order to operate the lift optimally. This should be very influential the building occupants comfort as lift users. One of the consequences of lack maturation of the lift planning is the queque during rush hours. As a result it is required some analysis of the existing elevator in Moch.Ichsan building. Elevator efficiency can be analyzed by calculated elevator needs that has a dependency on several variables such as speed lift, lift capacity, lift waiting time, number of buildings' residents, and how large the building is. While lift effectiveness could be obtained from schedulling preparation and budget needs involved in any preventive maintenance lift. Research methodology used in this study are interview, observation, secondary data collection, and data processing. From the results of data processing can be concluded that the efficiency and effectiveness of the elevator by 75% lift need are 4 units while the lift provided only 3 unit. The result also showed some schedule preventive maintenance and preventive maintenanceon lift budget in one year period.

Abstract

Penggaron area is one of the places that produce bricks in the city of Semarang. In producing it, then it will generate waste that is the brick itself. On the other hand the use of paving blocks are increasing with growing age. Various innovations have been made in making paving block one broken bricks using waste as a substitute material fine aggregate sand. The purpose of this study is the utilization of waste broken bricks Penggaron as a partial replacement of sand in the manufacture of paving blocks, as well as to determine the optimal compressive strength of paving blocks are made with a mixed composition 1 PC: 6 Ps (control group); 1pc: 5 Ps: 1Bt; 1pc: 4 Ps: 2 Bt; 1pc: 3 Ps: 3 Bt; 1pc: 2 Ps: 4 Bt; 1pc: 1 Ps: 5 Bt. The test object is made rectangular with a size of 21 cm x 10.5 cm x 6 cm. From the test results 28 days highest compressive strength achieved by paving block with a mixed composition of 1: 6 in the amount of 193.44 kg / cm2. And the lowest compressive strength achieved by the composition of the mixture of 1: 2: 4 that is equal to 102.63 kg / cm2. From the graph has been created, obtained the equation y = -13,78x + 197.12 as well as the correlation coefficient R of 0.5791. The equation shows that the increasing mix of brick lower compressive strength and the R value implies a comparison mix (cement: sand: bricks) have a rather low influence of compressive strength.
