Abstract

Traffic accidents are a problem, especially on toll roadsbecause toll roads are designed as highways with high levels of comfort, smoothness and safety The number of accidents on Indonesian toll roads is still high. This research is expected to be able to address the above problems, especially the identification of accident-prone locations (black spot), accident characteristics, and proposed treatment at black spot.  The location of the study was the Jagorawi Toll Road (2015 - 2017) for 49 Km. Identification of black spot used the Accident Equivalent Rate (AEK) method, and identified locations prone to accidents (black spot) on Jakarta - Ciawi route were Km 08 - 09, Km 22 - 31, Km 33 – 37, and Km 39 – 43, while on Ciawi - Jakarta, tracks were Km 04 - 09, Km 21 - 23, Km 28 - 29, Km 34 - 35, Km 40 – 41, and Km 44 - 45. Identification of accident characteristics using data approach analysis and statistical analysis were fine weather, one-lane, 00.00 - 06.00, lack of anticipation, self-accident and mini bus. The proposed handling of accident-prone locations (black spot) to reduce the number of accidents is by Minimum Service Standards (MSS) of toll road safety, such as traffic signs, street lighting, rumble strips and other toll road safety equipment. Keywords : Black Spot, Equivalent Accident Number, Accident Characteristics.

Abstract

Concrete is composed of three main constituent materials, namely cement, aggregate and water. The development of concrete technology in the trial of adding a mixture of materials continues to be done to achieve the desired strength and quality. In this experiment, the addition of gypsum waste was used as a concrete mixture to determine its effect on the compressive strength of concrete. The variation in the percentage of the addition of gypsum waste is 5%, 10%, and 15% with the age of treatment observed at 14 days and 28 days. The results showed that the normal compressive strength value at 14 days was 186.87 kg/cm2, while with the addition of gypsum waste mixture the concrete compressive strength at 5%, 10% and 15% were obtained 178.45 kg respectively /cm2, 101, 01 kg/cm2, 70.71 kg/cm2. Meanwhile the compressive strength value of normal concrete at 28 days is 164.44 kg/cm2, and the compressive strength value of concrete after mixed with gypsum waste at 28 days is obtained 157.04 kg/cm2, 88.89 kg/cm2, 62.22 kg/cm2. Based on the results it can be concluded that the addition of gypsum waste as a concrete mixture material can reduce the compressive strength values of normal concrete. Keywords : Concrete, Compressive Strength, and Gypsum Waste.

Abstract

The increasing needs of community travel in DKI Jakarta area that is not balanced with the growth of roads have resulted in traffic congestion. One effort to address the problem is to implement a traffic restriction policy using Electronic Road Pricing system (ERP). This research aims to analyze the existing condition of traffic characteristics on the road sections reviewed, analyze the opportunities of road users mobility against ERP system, and analyze the potential implementation of ERP system. Data collected from traffic survey results and distribution of questionnaires to users of four-wheeled vehicles. To analyze the existing condition of traffic characteristics using the calculation method of Pedoman Kapasitas Jalan Indonesia 2014, and to analyze the chances of  road users to ERP system using binary Logistic regression analysis method. Meanwhile, to analyze the potential implementation of ERP system is to compare the cost of congestion before ERP with predictions when ERP policy is implemented. From the results of the calculations and analysis, the road condition will experience a decrease in vehicle volume by 50% when ERP system is applied so that the degree of saturation in the road is very good compared to the condition before implementation of ERP system. Besides, there are congestion cost savings of Rp.532,291.998/hour for rush hour and Rp.294,167.785/hour for peak hours when ERP system is implemented. Therefore, the result is that the ERP system has good potential to be applied to reduce congestion in DKI Jakarta. Keywords : Congestion Cost, Traffic, Electronic Road Pricing (ERP), Displacement Opportunities.

Abstract

The West Sumatra Earthquake on September 30, 2009, which also hit Padang City, caused most of the buildings to be severely and slightly damaged. This paper discusses the types of damage, repairs and reinforcement of residential houses in Mekar Melati Housing, Lubuk Minturun Sub-District, Padang City, West Sumatra. Data were collected using direct survey and assessment on both houses that have been severely damaged or slightly damaged. After the 2009 earthquake, the residential houses in the Mekar Melati housing complex in Lubuk Minturun, generally suffered severe damage and slight damage. The reason is that the building there is included in the category of very simple houses. Building materials used without slof, let alone walls that only use hollowbrick material, of which if the material is not plastered it will become brittle, resulting in the building easily collapsing. Keywords: Damage, Earthquake, Residential Houses, Repairs and Reinforcement.

Abstract

High-rise Building construction projects can be said as high-risk projects, this is based on the construction process which usually takes a long time and is complex, so that it can cause uncertainties that create various risks. Risk is a combination of the probability of an event and the impact of that event. The impact of risks can affect productivity, quality and project cost budgets. The purpose of this study is to identify the risks that occur in the magnitude of the influence on building construction projects and analyze the risk responses that occur at building construction projects. In this research, risk analysis, risk identification and risk response carried out at two different building construction projects with two different contractors. Risk identification carried out by conducting a literature study, assessing the frequency / probability of risk and assessing the impact of risks using the Severity Index, identifying risks using the Probability Impact Matrix. From the results of the analysis it has been concluded that there is one risk variable that is included in the large category, the risk variable is the "estimated time error". The risk response discussed is to the estimated time error, design changes and changes in the schedule of work implementation. Large percentage of risk variables, which affect the performance or implementation of construction projects is the estimated time error of 67.8%, a change in design: of 23.9% and changes in the work implementation schedule of : 8.3%. Keywords : Risk, Risk Response, Building Construction Projects.

Abstract

Indonesia is a country with geographical location where 4 large tectonic plates meet. Therefore, if a collision or frictionhits the country, it is vulnerable to earthquakes. This condition makes the buildings more vulnerable to earthquakes. The effect of earthquake force and the performance of the resulting structure will be different if the same load is applied to a regular building and to an irregular building. The method to calculate the effect of the earthquake on the analysis of high-rise building structures in this study used dynamic analysis with spectrum response referred to SNI 03-1726-2012 and 2013 ETABS software program assistance (13.1.1 build 1035). This study aimed to compare the performance of the structure based on the deflection value and the story drift limits in regular and irregular buildings. In this study, the response of structural performance on three building models was calculated with variations in horizontal structure irregularity and then the results were compared. In this research, the biggest deflection was resulted on the re-entrant corner irregularity model C in the x-direction of 7,219 mm and the y-direction of 4,244 mm. Based on the deflection value in the x-direction and y-direction on all building models, the story drift due to the effect of the earthquake plan was less than Delta-a, wherein this study obtained Delta-a by 80mm, so it could be concluded that it was safe against the story drift limits in SNI-03-1726-2012. Keywords: Spectrum Response, Deflection, Horizontal Irregularity.

Abstract

Some damages of the Jalan Lintas Selatan Road, Suradita-Kranggan has occured every year with the identical failure cycle. One of the effort to make problem solving is to replace the base of road body construction with a concrete plate construction supported by circular pre-stressed concrete pile foundation (spun pile) system. The system will carry on the upper structure or embankment (subgrade) since the below of the structure exists soft soil layers and the depth of hard layer soil reachs more than 10 m. Later on, all vertical and horizontal forces including moments caused by the external loads can be retained by the plate and spun pile foundation system. The purpose of the study is to calculate the bearing capacity, negative friction force, settlement of spun pile group with using field test data (SPT and CPT); and diameter variation of pile is 30 cm to 50 cm. From calculations with the average length of 1400 cm and diameter of 50 cm can be determined bearing capacity of 298.9 tons by SPT and 504.3 tons by CPT data, respectively. Then, lateral bearing capacity is 168.5 tons (free pile head) and 344.2 tons (fixed pile head). The settlement occurred of a single pile foundation is 9.40 cm. The results of negative friction resistance were obtained is 81.9 tons. The group piles is designed of 2 (two) rows and 3 (three) columns and can be safe for receiving the construction and traffic loads. Based on the analysis results, the concrete plate and spun pile system has fullfilled to design criteria. Keywords: Spun Pile, Bearing Capacity, Negative Friction, Settlement, Pile Group.
