The increasing of urban population growth would affect to the increasing settlement growth which expanding uncontrollably toward the suburbs, this condition will influence transportation problem and 70 % air pollution comes from transportation sector (BAPEDAL in 2006). Semarang cities as case study deals with congestion problems in almost all road network; the most surprising thing is with the presence of mass transit services which is BRT, both BRT corridor I and corridor II, it still have a load factor of 27% (Ilham Hussein, 2012). This study aims to: manage environmentally sound public transportation based on the characteristics of people and city of Semarang. The result of study concluded that in order to manage environmentally sound transportation by creating an unified and integrated mass transit; which is by cutting the BRT routes that are less effective and too long, directed to feeder transport from the tip end of track to the end of beginning of peple mobility with a public transport like mini bus for a distance of > 500m and bike or walking track to feeder within 200 â€“ 500m equipped with convenient bicycle and pedestrian infrastructures. Whereas, for the suburbs mobility to other suburbs it can use rail-based mass transportation (MRT).

The risk of the high-strength concrete is in line with the increase of temperature, especially for concrete slab where the surface exposure is relatively wider than beams or columns. The effort to overcome the problem has been carried out, amongst other is to cover with blanket namely fire proofing. This research is to conduct the characteristics of concrete slabs under fire exposure. Eight samples were cast with concrete having compressive strength of 52,68 MPa and were reinforced with high-strength steel having yield stress of 600 MPa. The samples which were of 60 mm thick, 600 mm wide and 1200 mm long, were equipped with reinforcement at 10 mm deep. Eight of samples were grouped into 2 samples each to represent 4 group. Each group represents the reference (type I), the ones with thicker concrete cover (type II), the ones with additional mortar cover (type III), and the ones with fire proofing product (type IV).Â Fire tests were conducted through all groups. and the test procedure follows the ASTM E119-88.Â The fire exposure was done in 30 minutes and the equivalent live load of 345 kg/mÂ² was provided during the fire tests. Three thermocouples were also employed at different levels of depth of concrete to monitor the heat transfer in the high strength concrete and one thermocouple was used for monitoring furnace temperature. The experiment shows that the application of fire proofing product is much more efficient in reducing heat of concrete surfases. The reductions of temperature for slab type II, III, and IV are of 56,44%, 68,145%, and 85,14%. respectively. Crack spreads more evenly in the slab ofÂ type I and II. Explosive spalling happens more at the reference slab in comparison to the slab with thicker concrete cover. The deflections of slab of type I, II, III, and IV after fire exposure are of 315,92%, 319,52%, 240,84% and 73,96% in comparison to maksimum deflections.Keywords: crack, spalling, high-strength concrete, fire proofingPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3917[How to cite: Sulistyawati, R., 2005, Pengaruh Fire Proofing pada Perilaku PelatÂ Beton Mutu Tinggi Saat Terbakar, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 3, pp. 1-12]

To date there were few research on the effect of non-linearity properties of the ocean waves on the performance of wave energy converter (WEC), which uses a series of unidirectional gear. One such parameter is the variation of wave period. The influence of wave period variations on the performance of physical model of the wave energy converters have been investigated at the Hydraulics Laboratory, Department of Civil Engineering, Hasanuddin University Indonesia. This WEC physical model was fabricated and assembled at Politeknik ATI Makassar Indonesia. The investigation steps consists of physical model development, physical model investigation at wave flume prior to the wave periodÂ variation, measuring input output parameters of the physical model under test and empirical model formulation based on observed data analysis. Physical model test carried out on the wave flume at the Hydraulics Laboratory of the Department of Civil Hasanuddin University, at a water depth of 25 cm, wave height between 5-9 cm and wave period between 1.2 - 2.2 seconds. Investigation result based on flywheel radial speed (RPM) and torque (Nm) indicated that calculated harvested power was inversely proportional with the wave period. The longer the period of the waves, the energy produced is getting smaller. The derived empirical formula was y = -85.598x + 208.53 and RÂ² = 0.8881. Y is energy produced (Watt) and X is the wave period (Second). Formulations generated from this study could be used as a reference for future research in dealing with wave period variations on a design one way gear wave energy converter as a source of renewable energy.

The slopes on river banks close to the estuary can be affected by tides, so it can experience stability in the river bank. Therefore, this research is conducted to determine the stability of river bank due to tides with numerical analysis. The numerical analysis method was done by 2D Plaxis Software that using theÂ Finite Element Method. The analysis was conducted on a homogeneous slope with 2 (two) different soil permeability coefficient values, there are low permeability and high permeability. The analysis is modeled by fully coupled analysis between deformation and ground water flow analysis. The results of the analysis indicate that a tidal are influence the stability of the slope based on the safety factor value. The highest of safety factor value are shown in high tide condition, and the lowest occur at low tide condition. This happens because the high tide condition occur the addition of hydraulic pressure from the water that will resist the sliding, while the low tide condition will reduce the hydraulic pressure. This can be a concern to the stability of river bank with tidal condition in order to avoid the erosion during the low tide conditions. The comparison of safety factors between two different types of soil permeability are not significant, the difference are only 3%.

In recent years, concrete with compressive strength in excess of 50 MPa has been utilized in building construction. However, many empirical equations used to predict properties of concrete or design structure members are based on test using concrete with compressive strength less than 41 MPa. Applicability of this design equation for high strength concrete structures may lead to conservative or even unsafe design. One such example is the provision for calculating development length of reinforcing bars which is developed based on bond capacity of steel bars embedded in concrete.The research study was motivated by the lack of test data on bond performance of reinforcing bars embedded in high strength concrete especially those related to high-strength fly-ash concrete. More than 35 specimens with various concrete compressive strength fcÂ¢ and bar diameter (deformed and smooth bar) were tested. The result of this experimental shows that bond equation from ACI is too conservative for high strength concrete structures.

The aim of this study is to find out the effect of annual rainfall on the erosion index and the life of a reservoir. The erosion index is defined as the total soil loss divided by the tolerable soil loss. The life of a reservoir is affected by the amount of sediment flowing into the reservoir and sediment trap, which is a function of the effective capacity of the reservoir and the inflowing water. Soil and Water Assessment Tool (SWAT) version 2005 model was incorporated into this study to simulate hydrological processes taking place in the catchment. ArcSWAT (ArcGIS Interface for SWAT 2005) program was used as a preprocessing tool to write in input files to be executed by SWAT.SWAT model involves a great number of parameters. Hence, its reliability depends so much on the data availability and some parameter adjustments. From the calibration and validation results on annual data, the model is considerably of good performance. This was proven from the coefficient of correlation (r), coefficient of determination (R2), model efficiency (ME), and index of agreement (IA) which are close to 1 except for the sediment inflow. The difference between the observed and simulated sediment inflow resulted because the SWAT model accounts for the annual variation in precipitation and mean inflow discharge which is not manifested in the observed data. The modeling results revealed that the average inflowing sediment into the reservoir is 5,102,000 ton/year resulting in 46.18 year effective life of the reservoir which corresponds to the critical degree of 1.15. The graph plotting the values of the sediment inflow and the critical degree of the reservoir life reveals a linear relationship.

The behavior of reinforced concrete frame with infill wall (RDP) has been studied numerically by modeling the RDP structure using the LUSAS software. The results were compared to other researchersâ€™ results that conducted laboratory test and used SAP programs. The results of analysis using SAP show that the proposed model that subjected to load up to the maximum limit show similar behavior to the laboratory tests results in which parameters such as secant modulus for concrete and wall materials based on graphs of stress-strain relationships and a reduction in moment of inertia due to the crack of beam-column are taken into account. The model using LUSAS did not adopt this method instead applied plastic elastic material and non-linear analysis. The results of the analysis are still not in proportional to the magnitude of the laboratory test results, but the behavior of the load and deflection indicates similar form. The analysis models show the maximum stress points that occur on the wall similar to that with the pattern of failure in laboratory testing. The maximum stress occurs at the opening corner and the beam column joint corner that is in line with the results of laboratory testing.

To increase the characteristic of asphalt mixture, one of is to add plastik or in chemical term called polymer into asphalt. Generally plastik is in pellet that is difficult for mixture with asphalt For kind of this should be use additional equipmentÂ where not available in all region or in Asphalt Mixing Plant Unit. Therefore, solution of that have to look for methodÂ mixture polymer without additional equipment. There are two kinds of mixing of polymer addition for increasing characteristic asphalt mixture. Is dry process and wet process. Wet processÂ can be performed by adding polymer into hot asphalt then mixed uniformly. Mean while, dry process can conducted by adding polymer into hot aggregate. The purpose of the research is to find out the performance of asphalt mixture as resulted from polymer LDPE addition both in wet and dry process at optimum asphalt content ofÂ asphalt pen 60 mixture from Marshall Test and polymer content 3.5% weight of asphalt where is same with polymer content from wet process. In a dry process, additional polymer to hot aggregate at mixing temperature and mixed for 35 â€“ 40 second. The research result in laboratory , showed that dry process method increased The Stability Marshall characteristics, Dynamic Stability and Resilient Modulus greater than characteristic of asphalt pen 60 mixture but lower than wet process method. Economically Dry process method is cheaper because of faster mixing time no additional mixer needed, easily handled compared to wet process method. Keywords: Asphalt, dry process, wet process, Optimum Asphalt content, polymer, characteristic of asphalt mixture. Â ABSTRAK Untuk menaikkan mutu campuran beraspal, salah satunya dengan menambahkan plastik yang dalam istilah kimianya disebut polimer. Umumnya plastik berbentuk pelet sehingga untuk mencampur dengan aspal diperlukan tambahan alat. Peralatan ini tidak selalu tersedia disetiap kota atau Unit Pencampur Aspal. Oleh karena itu perlu dicari solusinya yaitu bagaimana menambahkan polimer tanpa tambahan peralatan. Penambahan polimer untuk menaikkan mutu campuran beraspal ada dua cara, yaitu cara basah (wet process) dimana plastik ditambahkan ke dalam aspal panas dan dicampur hingga homogen dan cara kering dimana plastik ditambahkan ke dalam agregat panas. Tujuan dari penelitian ini adalah untuk membandingkan pengaruh kedua cara pencampuran plastik mutu rendah jenis LDPE terhadap kinerja campuran beraspal pada kadar aspal optimum, yang sama dengan kadar aspal optimum hasil pengujian Marshall aspal pen 60 sebagai pembanding (balnko), sedangkan kadar plastik adalah 3,5% terhadap berat aspal yang diambil dari hasil pengujian variasi kadar plastik terhadap mutu aspal yang telah dimodifikasi dengan plastik (cara basah). Pada cara kering plastik dengan kadar sama dengan cara basah ditambahkan kedalam agregat panas (pada temperatur campuran) dan diaduk selama 30-45 detik. Dari hasil yang diperoleh di laboratorium menunjukkan cara kering menghasilkan karakteristik Marshall, Stabilitas Dinamis dan Resilien Modulus lebih besar dari aspal pen 60, namun lebih rendah dari cara basah. Dari segi ekonomi cara kering diperkirakan lebih murah karena waktu pencampuran lebih cepat,Â tidak memerlukan alat pengaduk (mixer) dan lebih mudah di handle dari pada cara basah.Kata kunci: Aspal, cara kering, cara basah, Kadar aspal optimum, polimer, kinerja campuran beraspalPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3695[How to cite: Suroso, T.W.

At this time, the architecture and design of the existing floor plan often changes according to the needs and tastes of the owner in accordance with the changing times. This research was conducted as precast concrete structures become even more important with the increase in man's desire to change the design of his home without spending enormous cost. This study aims to investigate the stiffness and study the behavior of precast concrete between monolith column with no connections and the column with connection. The connection used is dry joint using a plate and screw nut. The results obtained are the stiffness of the test specimen column with no connections is smaller than the test object column with connection. The modulus of elasticity of the column without a connection greater than the column with connection. Cracks that occurred in the test object columns without connection occurs faster than the test object columns with connection and both, flexural cracks occur first and then cracked in shear.
