Abstract

The objective of this research is to get the behaviour of Meranti wood beams as a material of Aceh traditional building. The behaviour is to  gain the relationship between load-deflection of wood beams test. Meranti woods are got from 6 locations of woods machinery i.e: 3 locations in the area Banda Aceh and other 3 lcations in Aceh Besar. The flexural test was used 5x7x120 cm wood beams size, and total 30 specimens.from those 6 locations. To get other supporting data, the other test  was done i.e.: physical characteristic and mechanical characteristic. Physical characteristic was done with specific gravity test, and moisture content test which are 10 specimens each test. Mechanical characteristic was done with  tensile test and compression test which are 10 specimens each test. The result of the test obtained moisture content was 13,19% at 28,9o C temperature. Average specific gravity was 0,429.  Tensile strength parallel to main fiber was  448,1 kg/cm2 at 0,53 % average maximum strain. Compression strength parallel to main fiber was  316,9 kg/cm2 at 0,41 % average maximum strain. Average modulus of elasticity from tensile test was found  84.547 kg/cm2. Flexural characteristic was a  relationship between load-deflection plotted as a graph in the text. Based on these result could be concluded that Meranti woods was appropriated to be material building Aceh traditional houses.

Abstract

Krueng Langsa  is a river crossing Langsa City the position is in the middle of residential and potentially catastrophic spills seasonal flooding. Krueng Langsa River watershed has an area of 126 km2, with a rainfall of 2300 mm / year and includes areas with relatively high rainfall. In the upper part of the river flow characteristics along the hills, while the central part of the narrowing of the river in the extreme. Hydrologic simulation based on rainfall data using HEC-HMS software obtained flood discharge of 59.30 m³ / sec. Passing the analysis of flood discharge capacity obtained on existing cross-section of 60.07 m³ / sec which is almost close to the value of the existing flood discharge based on the model HEC-HMS. HEC-RAS analysis results with simulation input Q2 years, to 140 pieces of the cross section illustrates that almost all river basins experienced flooding conditions (overflow), and only a few parts that are not experiencing flooding conditions. This is because the flood water level exceeds the elevation of the bank. Scenario flood control is done by normalizing the river, which enlarge the dimensions of the existing river with a wide cross-section of the river on average 20 m to 60 m and planning at the river levee embankment crest elevation +2.00 m and surveillance (freeboard) 0.50 m of surface water flooding . At the mouth of the river, starting from the point STA.0 + 000 to STA.2+ 000  planned use of the river revetment rock pile (Dump Stone). Both scenarios flood control can be recommended to reduce the flooding that occurred in the Krueng Langsa river.

Abstract

The objective of this study is to provide an alternative design of sediment problems in Kuala Raja Port that causes disadvantages for the local fishermen due to ineffective port utilization. The primary surveys conducted in this study are topographic survey, bathymetry survey, current survey and geological survey. The wind data is obtained from the Malikul Saleh Meteorological Station. Based on the tidal survey, the water surface during the tide water is 1,56 m above  0.00 m LWS. The current data shows that the flow rate is low, which is less than 1.5 m/sec whereas not interfere ships’ movement, because the standard size of ships allowed crossing the shipping lanes is planned less than 50 GT. Based on the correction using SPM nomogram acquired high waves 3.50 m with wind speed > 20 knots and the North largest fetch  490.04 miles. Sediment transport on shore of Kuala Raja beach is  46,934.59 m3/year moves from West to East. The hand bore data on the location of the planned jetty obtained SG = 2,648, Wc = 25.66, gd = 1,549, f = 31.00, c = 0.03. Therefore, the determination of the layout of jetty at Kuala Raja Port is considering the direction of sediment transport, the wave height that occurs, the field data attained and the economic feasibility. Sediment management at the Kuala Raja Port can be done within 2 (two) ways: firstly by increasing the length of the jetty on the left and the right side and, secondly by dredging the navigation channel. The length of the jetty that is needed to expand on the left side is 284 meters long and 127.65 meters long on the right side, in order to avoid the addition of sedimentation volume. The jetty’s slope is planned 1: 2 outside the channel and 1: 1 inside the navigation channel. The dredging volume at the port entrance is approximately 39,811.60 m3.

Abstract

The purpose of this study is to create an economically effective flyover construction in Medan so that this study can inspire the local official. Total cost of the construction is Rp. 720 billion which consist of  Rp 10.8 billion of flyover base structure construction cost, mobilization and road hardening cost, design and supervision cost; Rp 7.641 billion annual maintenance unit cost; Rp 22.923 billion/5 years periodically maintenance cost; and Rp 4,375,000/m2 estimated  land acquisition cost. The calculated benefit is travel cost cut-off which is the difference between the total travel cost with and without project. The travel cost consists of Vehicle Operational Cost and Time Value. Based on year 2014 analysis, the total amount of the cut-off saving of Simpang Selayang Flyover is Rp 30.06 billion. Economic feasibility analysis of horizon years for 30 years showed that the benefit obtained based on NPV, which is Rp 61,1 billion, is not adequate enough for 12,5 % annual interest rate, this can be seen by the 10.99% Internal Rate Return (IRR), so, the value of Simpang Selayang Flyover construction is not economically feasible yet.

Abstract

Transport models are crucial in the transportation planning process. Transport model is made by adjusting the needs and availability of data and capability models in representing the real conditions and the future. Transportation models commonly used in transportation planning mechanism is the sequential demand models, which include the trip generation, trip distribution, mode choice, and traffic assignment. This model is suitable to be applied to various situations study areas, especially areas of the city. For intercity regional planning needs, modeling the sequential demand can be simplified into a direct demand model, the record is not much involved in modeling mode. In this study, the authors tried to develop a model of a direct demand models to represent the pattern of movement of people with other modes of road in West Java. The proposed transport model is a function of population, GDP, total number of trip generation traffic zone, the total transportation costs (generalized cost). Model results show the validity of the development of significant and can be used as a travel demand model for transportation planning.

Abstract

The value of travel time becomes an important part of the gains in the assessment of a transport project in terms of economic considerations. In this research, the calculation of the value of travel time for users of private vehicles in Banda Aceh. Purposes of calculating the value of travel time is to vote as a result of a wasted opportunity when used to produce something as a result of traveling purposes. Of the various methods that can be used to determine the value of travel time method selection transport modes (mode choice approach) with a stated preference survey data is either to be used in determining the value of time based on the use of public transport (labi-labi) as the second choice , but taken one more method is the method of income (income approach) as a comparison. As for the results in this study is the comparison of both methods is the method of choice of transport modes (mode choice approach) and method of income (income approach) to obtain the value of travel time for users of private vehicles in the city of Banda Aceh.

Abstract

The construction industry is a vanguard in developing countries, including Indonesia. It has unique characteristics where complex works exist. These characteristics distinguish this industry from other industries in economy. Its project involves so many risks that have potentially business failure. Failure, bankruptcy or insolvency is unpleasant words, but people in the industry cannot ignore them. This paper thoroughly explored the causes of insolvency in Construction Company due the procedure of competitive tendering in Indonesia and how to avoid it. Insolvency in Indonesia is caused by lack of business experiences, country’s economic condition, poor control of cash flow, cannot convince clients, and low profit margin as a result of competitive tendering. Some researchs found that insolvency can be predicted at early opportunity, and some methods are applied to prevent insolvency.

Abstract

The aim of the tests was to investigate the influence of concrete strength, the eccentricity of the column and the use of shear reinforcement in flat slabs on punching shear. The research specimens are 8 units of flat slabs. Flat slab size 1400 x 1400 mm2 with thickness of 120 mm. Flat slabs were connected with circular column with dimension 225 mm  of diameter and 200 mm of height. Flat slabs were made in to 2 variations of concrete strength, e.i. 30 MPa and 60 MPa, 2 variations of shear reinforcement, e.i. without shear reinforcement and with shear reinforcement and 2 variations of eccentricity that, e.i. without eccentricity and with eccentricity. Each treatment has 1 specimen. Each specimen has 6 cylinder specimens. Cylinder specimens used as a concrete strength control for main specimen (flat slab). The tests showed that the concrete strength had a strong influence on punching shear strength. This is shown by capacity increase of 42.78%; 54.00%; 46.59% and 0.02%. The value is ratio between the maximum load of the specimens with 60 MPa and 30 MPa at the same eccentricity and the same shear reinforcement. The eccentricity of column reduce the capacity of punching shear. This is shown by 3 specimens decrease in capacity of 3.70%; 36.75% and 7.30%. Only 1 specimen that increase in capacity of 9.27%. The value is ratio between the maximum load of the specimens with 40 mm eccentricity and 0 mm eccentricity at the same compressive strenght and the same shear reinforcement. The use of shear reinforcement does not always increase the punching shear capacity. There are 2 observations that increased capacity (52.07% and 65.37% at the centric load) and 2 observations decreased capacity (0.12% and 4.92% at the eccentric load). The value is ratio between the maximum load on the specimens using shear reinforcement with the specimens that do not use shear reinforcement at the same compressive strenght and the same eccentricity.The use of shear reinforcement increase punching shear capacity of flat slab at the centric load condition. The use of shear reinforcement decrease punching shear capacity of flat slab at the eccentric load condition.
