Abstract
A slope has a high tendency to slide due to many factors coming from combination of external loads and internal soil properties itself. In any construction design, two things should be taken into account are stability and settlement. In case of landslide, slope is not stable, mobilizing stress in slope is higher than allowable stress. In order to reach target slope stability, earthwork solutions and or ground improvement solutions can be conducted. This study with the objective to propose some alternative earthwork solutions that have sufficient stability, soil test is performed. In this experiment, soil is taken from landslide location in Jepara, Central Java. The soil test aims to investigate index and engineering properties used as an input. In order to model earthwork in slope and to obtain its safety factor, application program Plaxis is used.

Abstract
Clay is a type of soil with high pore water characteristics which causes its problem for pavment. Ujung Kulon national Park road in Sumur Subdistrict, Pandeglang Regency is a road with clay soil type, so the road is often demaged. To overcome this its problem it is necessary to add strength and improve its bearing capacity. One of the way is by doing a method of Stabilitation on the soil in that location. The addition fly ash and carbide waste is one of the effective ways to stabilize clay soil, since fly ash and carbide waste have properties that are able to bind the soil to solid and increase the value of the soil strength. The research aims to determine the classification of soil, soil plasticity index, and find out the effect of adding fly ash and carbide waste to the soil physical properties, as well as to find out the value of the soil compression strength in existing condition and after mixing fly ash and carbide waste.The water content of the sample taken from the compaction of the original soil standart proctor. The variation of fly ash mixture that used is 0% and 20% and carbide waste with a mixture of 0%, 5%, 10%, 15%, 20% and 25%. Based on the result, the soil which stabilized by fly ash and carbide waste in the variation of 0%, 10%, 15%, and 20% showed the increase of the value of the soil bearing capacity, and decrease the velue of soil plasticity index.the largest of UCT (Unconfined Compression Ssrenght) value result for soil sample mixed with 20% fly ash and 20% carbide waste contain by curing for 28 days in amount of 5,51 kg /cm2. Curing effect on the compressive strength for fly ash has pozzolanic properties that is like cement takes time to strengthen binding and carbide waste has the cemichal compound needed by clay in the particle binding process.

Abstract
Falling Weight Deflectometer (FWD) is the standard equipment used for the analysis and evaluation of flexible pavement. The number of this equipment is very limited in Indonesia. For a country owned 48,000 kms of road it is quite important to have an alternate equipment of FWD. Institute of Road Engineering (IRE) has performed the Light Weight Deflectometer (LWD) for the use in low to medium traffic roads for both evaluation and design of overlay. The study has done to compare these two equipment focusing on three parameters i.e Effective Structural Number (SNeff), Surface Modulus (Sm) and prediction of Subgrade Modulus (Esg). There are 30 points tested using FWD and LWD nearly in the same time on the IRE campus that is classified as low traffic volume road. Each point is then analysed to calculate SNeff, Sm, and Esg using the deflections derived from both of FWD and LWD tests. It is found that the differences of these parameters are not too significant and falls below 10%. This findings go to the conclusion that the use of LWD of IRE version is acceptable to be used for the analysis of the flexible pavement especially for low to medium traffic roads.

Abstract
Palu-s earthquake was happened on September 28, 2018, provided the liquefaction hazard. Liquefaction was evaluated by shear wave velocity (Vs) obtained from the average Vs that occur along 30 meters. Not only Vs, but qu or end resistance also, obtained from the CPT Test. And the last is N-SPT. The highest value that influences the occurrence of liquefaction is the value of qu. This is because the CPT test has only a few error factors which are only in the form of conus, while the others are SPT in the amount of hammer, high distance of the fall, sampling technique. Whereas Vs, the shear wave data processing and calculation processes are on average Vs30 or AVS30.

Abstract
Structure failures often happen whether caused by bad planning or implementation, especially at a reinforced concrete bar. Failures on building structure elements might be caused by several factors such as planned age of use, transformation on building function, and even improper construction procedure or method. Thus, the reinforced concrete bar strengthening is required especially on a 10 m bar. This study focus is comparison on strengthening the original structure of the building using the CFRP method which overlaying the bar surface, adding the IWF bar as a cantilever from below of the desired structure, and enlarging the bar dimensions. The result of the study shows that using 5 m2 CFRP overlayed on flexible reinforcement and 2.5 m2 CFRP overlayed in shear reinforcement results in Mn = 207.82 Knm and Vn = 146.33 Kn. Furthermore, additional 400,400,13,31 IWF bar for the strengthening result in Mn = 1045,32 Knm and Vn = 809,79 Kn. Finally, the dimension enlargement to 650 mm x 350 mm of 4D16 reinforced concrete and P10-250 mm reinforced cross-bar result in Mn = 529,23 Knm and Vn = 78,56 Kn. Effectiveness analysis is done to select the most effective method considering its strength gained and the cost required.

Abstract
Estimating axial capacity of piles using Direct Method is still considered as a challenge these days. Estimation mainly achieved after construction is done and field method such as Static Load Test or PDA are used for calculating axial capacity of piles in real field conditions. This paper discussed estimation from 8 building project cases from Jakarta and Depok that have complete Standard Penetration Test data and field calculations (Static Load Test & PDA). The main objectives are to observe and correlate the results between every Direct Methods and field methods and to obtain which Direct Method is the most efficient to use for estimating axial capacity of piles in Jakarta area. Direct Methods that are used are Meyerhoff, Shariatmadari, Decourt, Aoki, and Robert. Calculation results showed that the most efficient standard penetration test method is that proposed by Decourt with average result of comparison between estimated axial capacity of piles and field calculation is roughly 1.03. The most underpredicted between every standard penetration test method is the one proposed by Aoki de Alencar with roughly 92% underprediction ratios and the most largest overpredicted method is proposed by Shariatmadari with roughly ratios of 56%.

Abstract
One of the causes of cracked reinforced concrete in the seawater environment is direct contact between concrete and sea water. This is because cement as a binding material in concrete does not have a good ability to withstand corrosive conditions in seawater. Ground Granulated Blast Furnace Slag (GGBFS) which in this case is B3 waste can be a solution. From several studies conducted previously, the behavior of GGBFS concrete against sulfate and chloride attacks showed positive results but relatively little is known about GGBFS material produced by steel mills in Indonesia. Therefore, an experimental study of the characteristics of compressive strength and permeability test using GGBFS (0%, 20%, 30%, 40%, 50%, and 60%) with 72 concrete cylinder in 28 and 40 days. Microstructure of GGBFS concrete test using Scanning Electron Microscopy (SEM) was also studied. The result of this experimental study is GGBFS microstructure, compressive strength and concrete permeability for better effectiveness concrete in seawater, so that it can become one of the alternative solutions for infrastructure development especially for seawater infrastructure in Indonesia.

Abstract
Reinforced concrete as a building structure plays an important role in holding the load. The combination of concrete and reinforcement in collaboration with the load is determined by the perfect bond of the two materials. Bond testing on reinforced concrete has been carried out. The axial load is given in reinforced concrete results in internal cracking of reinforced concrete around the threaded reinforcement area. An area within the radius of cracking of the concrete around the reinforcement has also been obtained. The action is needed to reduce the area of cracked concrete by giving restraints using spherical spiral reinforcements within the concrete crack radius. It is expected to increase the strength of the reinforcement and concrete around it. The restraints using plain reinforcement in the area have been carried out. The methodology used is Pull Out on single reinforced concrete cylindrical specimens with confinement and without confinement. Concrete cylindrical test specimens with a diameter of 150 mm 200 mm high with single reinforcement with a diameter of 10 mm, and spiral reinforcement as confinement with an identification diameter of 4 mm and spacing of 22.5 mm and 45 mm. Placed within the radius of cracking of the concrete around the reinforcement. Pull out the test is carried out with gradual loading until it passes. The Pull Out test results indicate a fault movement from the edge that is loaded to the free end. The spiral coil of reinforcing steel as a restraint is relatively insignificant and increases strongly. The restrained specimen produces a larger fault at the end of the load, when the initial fault occurs at the free end, compared to the specimen without restraint. The difference in the increase in stickiness with the spiral spacing of steel reinforcement 22.5 mm and 45 mm has not been seen.

Abstract
Pusjatan-s LWD is a equipment that is purposed to measure the structural strength of a pavement system especially unpaved roads. When the load of LWD falls, it generates vibration recorded by geophones. By using the principles of vibration theory then resulting deflection can be calculated. The deflection value is used for the calculation of modulus elasticity of soil using Boussinesq formula. The LWD is applied to Pusjatan-s yard in Bandung for sample of subgrade, where in each location we have taken ten data using LWD and DCP on the same tested points. The reason of comparing between LWD and DCP is that the former equipment used to measure the subgrade structural strength. The test results are a modulus elasticity then correlated with each other. The test results obtained the determination coefficient r2 = 0.7558, this means that the correlation value is 75.58% determined by the modulus of elasticity value of the DCP measurement, whereas on hard soil the correlation between modulus of elasticity of LWD with DCP Index, with the results r2 = 0.9684 or 96.84%. This indicates a strong correlation. This finding comes to the conclusion that Pusjatan-s LWD can be used to test structural strength of subgrade

Abstract
Ultrasonic Pulse Velocity (UPV) test includes a simple Non Destruction Test (NDT) testing method, by utilizing ultrasonic waves. In the implementation of UPV testing with direct, semi-direct, and indirect methods give a quick result of different pulse velocity, with the same quality of concrete. Therefore, this study was conducted to get the correlation and correction value of all three testing methods with PUNDIT Lab+ tool on reinforced concrete. The study used a speciment of concrete beams 15x15x60 cm3 with concrete quality K-275, K-250, K-225 each as much as 3 specimen. The average value of the measurement result with the direct UPV method is 12%, 7% and 5% less than the average value of the semi-direct method of UPV direction vertically, the semi-direct method of the UPV direction horizontally, and the indirect method UPV. Conversion of the measurement results for the direct UPV method of the semi-direct UPV vertical direction, semi-direct UPV direction horizontal and indirect UPV can use the regression equation Vd = 0.2462 Vsd-v + 3192, Vd = 0.1073 Vsd-h + 3923.8 and Vd = 0.0195 Vin + 4341.8.

Abstract
Waterfront area currently has a potential as a face of the city, it should not only being the behind area of the city. Waterfront area can be a tourist destination and a place that create social interaction, so that area can be the center of economic growth for the city especially in the field of tourism activity. Waterfront development experience many problems such as the loss of place quality. In the other side, private investment is not clearly regulated and causing the privatization of land in the shoreline area that should be the public space. Communities that received the impact of the development in the shoreline area are not to get involved in the planning process. These conditions impact that people can not freely access the beach. It happens because currently there is no policy to regulate and control the growth of the area as a tourist destination. This study formulates the design of tourism public space in a seaside area with attention to the image of an area and have the quality of public space. By analyzing the design area both regionally and environmental context, and including aspiration preferences of each stakeholders interest in the findings obtained several principles that need to be considered to create a coastal tourist area as public space. In this study, planning and designing is required to involve the community as a preferences and created a partnership program between the investor and the government as policy makers. With this cooperation, the growth of coastal resorts can be run as a shared vision that avoids conflicts of interest.

Abstract
Pressure Build-Up Analyses on a heavy oil well would give an inconclusive result on pressure derivative curves. Some kind of Thermal Injection should be performed prior to implementing the operation of Pressure Build Up test, where the heat will lower the heavy oil reservoir fluid. Sensitivity of several parameters namely viscosity, permeability, porosity, and shut-in time were used in designing Pressure Build Up test. The model also has an outer boundary. This sensitivity would give various reservoir reach of the test or radius of investigation. The sensitivity test showed that viscosity influences more on radius investigation as compared to permeability, porosity, and shut-in time. Since the Pressure Build Up test must reach radial flow period before pressure transient arrives at the nearest boundary, the test scenarios with viscosity range from 5.602 to 24.796 cp were suitable for the well. Furthermore, the study was continued to correlate radius of investigation as a function of the parameters mentioned above. A constant value of the correlation obtained from this study was 1197.

Abstract
Abstract. Building Maintenance is to maintain the reliability of buildings, infrastructure and facilities so that buildings are always worthy of function. The condition of maintenance buildings right now is generally still conventional and does not have a clear maintenance information system. As a result, the process of building maintenance tends to be slow, often overlooked, unstructured and can often result in insignificant additional costs. The purpose of this study is to improve the performance of the maintenance of green buildings in states-s buildings for architecture components. By developing information systems for maintenance, it is expected to improve the performance of maintenance in buildings. The case study examined was the State-s Building of Kementrian PU. The development method is based on Minister of Public Works Regulation No.24/2008 which are then integrated into the Information System with the WEB. The results of this study will be in the form of a web-shaped information system that is useful for State-s agencies and others in carrying out the maintenance work of government buildings, especially in the architecture component.

Abstract
In government buildings, facilities and infrastructure that can support the fulfillment of a function are needed, but the longer the buildings are in use then they will suffer damage from various aspects such as architectural components of the buildings. To reduce the occurrence of damage to buildings there is a need for preventive maintenance works. Preventive maintenance works could include a action taken to prevent the need for repairs. In the preventive maintenance work process of a building, the scope of work can be arranged using Work Breakdown Structure (WBS). So, that a structured grouping and oriented activities can be obtained and also works done in the project can define the overall scope of the project. But in the case of the government buildings, guidance provided by preventive maintenance works using WBS standards are lacking. Therefore, guideline development for preventive maintenance works is an important to improve the performance of maintenance. The purpose of this study is to develop guidelines for WBS based preventive maintenance works of architectural component of a government building. Research methodology includes several stages, namely the literature study, analysis of archival data and information from related studies and projects, case study, through validation with experts. The results of this research is in the form of guideline for WBS based preventive maintenance work for architectural component of government buildings that can improve the quality of the building and the effectiveness and efficiency of the maintenance of the building.

Abstract
Construction is one of the main projects that is stated in the Universitas Indonesia (UI) Strategic Plan-s Key Performance Indicators. Therefore, the success in carrying out this construction projects is enough to enhance UI-s annual performance overall, both the activity performance and budget performance. But in practice, the implementation of construction projects in UI didn-t always succeed as expected. The construction projects were often late or delayed which subsequently followed by the termination of the contracts, it would then hamper the operational activities. This study aims to develop a Quality Management System (QMS) of construction procurement process to improve the quality of contractor-s performance. The research methods used are literature study, survey to targeted respondents, and statistical analysis. This QMS development is expected to improve the quality of contractors by a better construction procurement process and be able to reduce the failure of the construction projects.

Abstract
The reliability of functioning mechanical components has major implications not only for the ease of use, lowering maintenance cost, avoiding loss of time and preserving safety factor but also for achieving green buildings mission namely emission and energy reduction. Failure in maintenance phase of mechanical components can adversely affect the achievement of the mission. Problems that occur are fragmented data, undocumented data, slow responses of human resource, and unscheduled maintenance. As a result, the massive budget spent in the green building construction phase is in vain. The purpose of this study is to improve the performance of maintenance of government green buildings in mechanical components by developing an information system that integrated with Building Information System (BIM). The case study studied was the Ministry of Public Works and People-s Housing Republic of Indonesia. The research methods used are literature reviews, case studies and system development. This study uses a Work Breakdown Structure (WBS) in managing data dynamically using BIM, which is integrated with web-based information systems. The result in this study is the increasement of performance in maintaining mechanical components of green building.

Abstract
The aim of building maintenance is to preserve the function, structure, and aesthetics of the building in accordance with the initial conditions. An ineffective building maintenance management leads to increased operation and maintenance cost, reduced building reliability, and failure to achieve the green building mission. One problem highlighted in this study is that building management are still using call-center system with no database to store building damage data, thus building failures are not detected in time. As a result landscape and housekeeping components are damaged below the allowable standard and become no longer functional. The purpose of this study is to improve the maintenance performance on landscape and housekeeping components of government green buildings. The case study studied was the Ministry of Public Works and People-s Housing Republic of Indonesia. The research methods used are literature reviews, surveys, case studies, and expert judgement for validation content and construct. This study uses a Work Breakdown Structure (WBS) in managing data dynamically using Building Information Modelling (BIM), integrated with web-based information systems. The result is that using BIM-based website leads to a more effective and efficient maintenance work of green buildings, thus improving the maintenance performance on landscape and housekeeping components.
