Abstract

Combideck slab was a floor slab that used a steeldeck as positive reinforcement and as formwork that hold the flooring concrete cast. While combined with wiremesh as negative reinforcement, the combideck system even more efficient than half slab casting method for concrete flooring system (Siregar, 2010). However, there is no standard method in Indonesia to analyze the flexure capacity of combideck. This study compared 3-analysis method (ultimate, working stress and SDI-ANSI) to laboratory test result that already done by Kadir&Sudarmadi (2008). Based on the published data, this study analyzed the combideck section properties to determine the theoretical flexure capacity, than it compared to the test result for validation. Besides that, this study also evaluated the reduction factor from the all 3 method to laboratory test result. This study validated that the working stress and SDI-ANSI method were accurate to analyze the slip flexure capacity, but the ultimate method was accurate for maximum flexure capacity. Because of the theoretical capacity form all 3 method was slightly greater than the test result (SDI-ANSI= 5.79%, working stress= 4.83%, ultimate method = 5.72%), the reduction factor from this study resulted as =0.76.

Abstract

Started from an innovative construction system programmed by the government to provide residential homes in 2007 that is the use of expanded polystyrene concrete as a wall construction. This type of construction provides advantages that can reduce the risk of damage in the earthquakes because it has a relatively light weight which is one of the requirements for earthquake resistant houses. For this reason, the bearing capacity of the wall panel is increased to become an earthquake resistant wall using reinforcement layers. Variations on this research are expanded polystyrene concrete panels without reinforcement, with reinforcement, and with reinforcement and bolt shear connectors. Strengthening uses a reinforcement of Calcium Silicate are Kalsi board. Testing based on SNI 03-3122-1992 (Fibrous Lightweight Concrete Panel). The results showed that the average value of the panel densities was 612,57 kg/m3, the elastic modulus was 942,37 MPa, compressive strength of 2,52 MPa and water absorption capacity of 12,11%. The highest flexural strength was obtained by the panel with kalsiboard reinforcement of 1,60 MPa. This results the addition of reinforcement layers will affect the increase in strength.

Abstract

According to Rencana Induk Perkeretaapian Nasional (RIPNas), making  plans for the development of Indonesian railways until the next 2030. The targets for the development of railway networks and services to be achieved in 2030 include a national network of 12,100 km (spread on Java-Bali, Sumatra, Kalimantan, Sulawesi and Papua). Construction of railway track is generally divided into two main types, namely, ballasted tracks and non-ballast tracks.  In this study the non-ballasted track or ballastless track is to modify the width of the sleeper  that will be used without using ballasts on the railroad tracks. This is done to reduce the use of coarse aggregates in ballasts so that if used in areas that do not have natural resources in the form of coarse aggregates a railway track can be built. The research will be carried out according to the condition of the soil gravel, dense sand, medium dense sand, silty medium dense dan loose sand. Different types of soil cause different responses or behaviors from the modification of the sleeper  that are located above the ground. This study will discuss the analysis of rail displacement and rail bending stress that occur in the modification of railroad concrete sleeper  for non-ballast use in some soil conditions. The study was conducted with software SAP2000 version 2014 to analyze  displacement and rail bending stress on concrete sleeper modification with dimensions 400 x 2440 mm2; 1200 x 2440 mm2; 2000 x 2440 mm2; 2800 x 2440 mm2 dan 3600 x 2440 mm2 for each different type of soil to determine the dimensions of modification of concrete sleeper  that can be used. According AREMA(1999) Result of rail displacement rail may not exceed 6 mm and rail bending  stress may not exceed 75 N/mm2.

Abstract

An evaluation of the condition and performance of the BBT Port needs to be carried out because of the significant increase in the number of tourist visits to the Bintan Beach International Resort area. Still, since its inauguration in 1994, the port has not changed much. Passenger terminal needs are commonly defined through projections using the exponential trend method based on ship and visitor flows in the last five years. A port performance is based on BOR (Berth Occupancy Ratio) calculation. In contrast, for the performance evaluation of passenger terminal services is based on the perception of tourists as passenger terminal users obtained from the questionnaire results with a Likert scale and the Importance Performance Analysis (IPA) method from the IPA, interviews with the BBT port manager, are conducted by using the Strength Weakness Opportunities Threats (SWOT) method to formulate the development strategy. The analysis result shows that it needs to increase the waiting area up to 613 m² in 2033, and the parking area of 17,173 m², while the BOR at the BBT port is still in a proper category, by  24.11% of the UNCTAD 50% requirement. In evaluating the passenger satisfaction to the port services, the improvement focuses on the priority quadrant, namely the physical condition of the BBT port facilities. Next, formulating a development strategy in terms of physical aspects and management to adjust the passenger needs, and the BBT port is ready to face business competition in the future.

Abstract

The western region of Sumatra Island is an area located on the world's active plate margin, which is reflected by the high frequency of earthquake events. An effort to reduce the impact of the earthquake disaster is to conduct a seismic hazard analysis. There have been many studies on seismic hazard in the West Sumatra region. Still, in the surrounding areas such as Riau, which borders directly with the territory, there has never been an earthquake hazard mapping micro zonation. This study aims to determine the value of surface acceleration for various districts or cities in Riau Province, by knowing the amount of surface acceleration, it will be able to identify the areas that have a relatively high level of earthquake risk. The Surface acceleration analysis is done by using the probabilistic Seismic hazard method (PSHA) using The SR Model software. The results of this study are obtained from 12 districts or cities located in Riau in which three areas have a high value of surface acceleration, those are Rokan Hulu regency, Kampar regency), and Kuantan Singingi regency). The amount of surface acceleration in Riau province in the 0.0 second period or peak ground acceleration (PGA) is in the range 0.097 - 0.78 g, then in the 0.2 second period the surface acceleration is in the range 0.204 – 1.943 g, and in the 1 second period of the surface acceleration is in the range 0.176 - 1.155 g.

Abstract

In the construction project, especially the roads in Yogyakarta and surrounding areas, the aggregate used is derived from the Clereng Kulonprogo. This amount of aggregate usage results in scarcity and affects the price to become expensive. The use of coarse aggregate materials as an alternative is rare. In reality, it is necessary to make innovation by utilizing the coarse aggregate of zeolite stone, which is still quite widely available in the Klaten area. Based on the preliminary test, the zeolite aggregate has a lower abrasion resistance compared to the andesite aggregate from Clereng. Using a modified asphalt Starbit E-60, which has a deficient penetration value, is expected to provide better stability to compensate for the weakness of zeolite stones. A combination of a mixture between a coarse aggregate of zeolite Stones and Andesite is tested until how large the proportion of zeolite stones of such combinations can provide the optimum value to AC-BC layer pavement. This research compares the performance of the AC-BC mixture using zeolite and andesite stones. It determines the feasibility of zeolite's stone, in substituting the andesite stone, in the AC-BC mixture. It is also to know the influence of the use of Starbit E-60 in the AC-BC mixture. The comparison of those performances was referred to as Marshall characteristics, Indirect Tensile Strength (ITS), and Immersion; using Pen asphalt Pen. 60/70 and Starbit E-60 as a binder. Trial mix was applied to the bitumen content variation of 5%, 5.5%, 6%, 6.5%, to determine Optimum Bitumen Content (OBC) by conducting Marshall testing. The variety of substitution zeolite proportions of 0%, 25%, and 75% was made in each trial mix above. The research result showed that the maximum percentage of zeolite aggregate in the mixture using an asphalt Pen 60/70, which meets with specification standard, is 28%, while the mixture using Starbit E-60 is 26%. ITS value decreases as the percentage of zeolite are increased. ITS value of mix with Starbit E-60 is higher than that of mix with asphalt Pen 60/70. Cantabro Loss value increases with zeolite proportion increase, for both mixed with Starbit E-60 and asphalt Pen 60/70. Cantabro loss of mix with Starbit E-60 is lower than that of with asphalt Pen 60/70. IRS value decrease with an increasing proportion of zeolite.

Abstract

Several causes can cause pavement deterioration; a weak subgrade caused one of them. If the pavement construction was built on the weak subgrade, it could damage pavement construction at the top of the subgrade. Chemical soil stabilization with cement and bitumen emulsion is one of the solutions to improve soil bearing capacity for pavement subgrade construction. The purpose of this study was to analyze the potential use of cement and bitumen emulsion as materials of chemical soil stabilization for pavement subgrade construction. In this study, soil samples were mixed by cement (3%, 6%,9%) and bitumen emulsion (3%,6%) and cured for 0, 3, and 7 days. The mixture of soil, cement, and bitumen emulsion was tested for soil bearing capacity and soil swelling by CBR and soil swelling test based on ASTM D 1883-99. Preliminary test results concluded that the original soil is included in class A-7-5 at the AASHTO classification system, and it is dominated by smectite clay minerals so that the original soil is expansive clay soil. The results of the compaction test reveal that soil stabilization with cement and bitumen emulsion can increase the mass of dry density of the soil. They reduce the optimum moisture content, where the variation of 6% cement and 3% bitumen emulsion can increase the mass of dry density by 1,340 gr / cm3 and reduce the optimum moisture content of 25%. The CBR and swelling test also disclose that soil stabilization with cement and bitumen emulsion increases soil bearing capacity and reduce swelling. The highest CBR values (soaked and unsoaked) are found in the variation of 9% cement and 3% bitumen emulsion cured by seven days, where the value is 56.9% (CBR Soaked) and 44.01% (CBR Unsoaked). The variation of 9% cement and 3% bitumen emulsion also can reduce soil swelling, where the value is 0,13%. CBR values at the variety of 9% cement and 3% bitumen emulsion cured by seven days have met the requirements of the road pavement subgrade based on SNI 03-1744-1989. Based on these tests, the cement and bitumen emulsion can use for soil stabilization material for subgrade pavement construction.
