<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[Design of buildings should pay attention to aspects; Strength, comfort, economics, and aesthetics. One aspect of the aesthetic that is often seen is the rain water pipeline from the roof to the channel on the ground. In order for this pipe is not be seen from the outside, it can be done by aasembling into thecore of the column so that it looks beautiful. To know the effect of hole in the column, need to do research. The aim of this research is to find out the influence of the variation of the size of the longitudinal aperture in the cylindrical specimen against the compressive strength of the concrete. The number of specimen were 20 pieces, consisting of 15 pieces of specimens given pipe holes and 5 pieces are not given a hole (intact). Variations of hole size, namely: 2.5 cm, 5 cm and 7.5 cm. Each variation of hole size of specimen 5 pieces. Concrete mixture design is done based on ACI method. The specimens used in this research are cylindrical shape specimens with diameter 15 cm and height 30 cm. Testing of concrete compression done at age 28 days. The test of the specimen is carried out by giving the compression load slowly until the specimen failured. The test results obtained the compressive strength of the specimen without hole = 266.48 kg / cm2; specimen with hole diameter 2.5 cm = 243,08 kg / cm2; specimen with hole diameter 5 cm = 226,22 kg / cm2; and specimen with hole diameter 7.5 cm = 190,13 kg / cm2. The results of this experiments show that the specimen with diameter of hole 2.5 cm is 91% of the specimen without hole, the specimen with hole diameter 5 cm is 85% of the specimen without hole; and the specimen with hole diameter 7.5 cm is 71% of the specimen without hole. The results of this experimen show that the larger size of the hole in the column the smaller the compressive strength of the concrete compared to the specimen without holes.]]>

<![CDATA[Sultan Iskandar Muda Airport Road, is the main access from Sultan Iskandar Muda Airport to the city and vice versa, because of these factors, it is estimated that this region has a high position and access to traffic in the future. The purpose of this study is to review the performance of roads on the Sultan Iskandar Muda Airport road based on time variations. The road section reviewed is 1 km with a width of 3.25 m. This road performance review was conducted using the 1997 MKJI reference. Traffic volume data, side barriers, travel speed and road geometry were obtained directly from field surveys for seven days of observation (06.30-08.30; 11.30-13.30; and 17.00-19.00), while Secondary data in the form of population and location research data obtained from relevant agencies. The analysis shows that the highest traffic volume occurs on Monday at 07:30 to 08:30 which is 1043 pcu / hour with a degree of saturation (DS) of 0.339 and the lowest traffic volume occurs on Saturday 06.30-07.30 which is 962 pcu / hour with a degree of saturation of 0.093. The value of the degree of saturation in the highest traffic volume (Monday), which is 0.339, is still far from the limit value of the saturation degree set by MKJI 1997, which is <0.75. This proves that the Sultan Iskandar Muda Airport road performance is still very good.]]>

<![CDATA[This study aims to determine the effect of the addition of carbide waste as a stabilizing material to the value of the CBR (California Bearing Ratio) and peat soil direct shear. The land used came from Lueng Gayo Village. The CBR value increased from 1.63% in the original soil to 17.09% in a mixture of 15% carbide waste, this is caused because the elements contained in carbide waste such as silica (SiO2) and calcium oxide (CaO) which act to fill the pore empty pores. The value of the shear angle (φ) has increased from 20.24o in the original soil to 29.02o in the mixture of carbide waste, this is caused by chemical reactions that occur due to mixing of chemical elements, especially (Ca) contained in the carbide waste. The cohesion value (c) has decreased from 0.12 kg / cm2 in the original soil to 0.09 kg / cm2 in the carbide waste mixture. This is caused by the reaction of carbide waste which is absorbing water, causing inter-particle decline. The value of the shear strength increased 0.22 kg / cm2 at the addition of 5% carbide waste, then decreased 0.17 kg / cm2 at the addition of 10% and increased 0.29 kg / cm2 at the addition of 15% carbide waste. This is due to chemical reactions that occur due to mixing of chemical elements contained in carbide waste]]>

<![CDATA[This study aims to determine the effect of the addition of oyster shell waste as a stabilizing material to the value of the CBR (California Bearing Ratio) and peat soil direct shear. According to USCS land is greater than 50%. The addition of oyster shell waste is done with variations of 0%, 5%, 10%, and 15%. The results of the value of dry weight (mengalamik) increased in the variation of the mixture of 0% by 0.86 gr / cm3 in the original soil and 15% by 0.946 gr / cm3 in the oyster shell mixture because this was due to the soil pores filled with stabilization vectors. The CBR value increased from 1.63% in the original soil to 11.62% in the 15% mixture of oyster shell waste. filling empty pores. The value of the shear angle increased by 20,230 in the subgrade to 33,370 in the 15% oyster shell mixture due to the chemical reaction contained in the oyster shell waste. The cohesion value (c) was 0.12 kg / cm2 in the original soil and increased by 0.13 kg / cm2 in the mixing of 15% oyster shell waste. The value of shear strength increased 0.18 kg / cm2 on the original soil and increased 0.31 kg / cm2 on the addition of 15% oyster shell waste.]]>
