Abstract
The magnitude of profit turnover in commercial apartments market, frequently led to the asymmetrical relationship between private sector as real estate developer and apartments owner as citizen. This condition was marked by administrative violations that are often carried out by real estate developers. Throughout 2018, the DKI Jakarta Government received various complaints related to the apartments management and operation, including conflict of interest and transparancy issues in the Apartments Owners and Residents Association (PPPSRS). Following certain agenda that had been pushed by civil society organizations since 2006, the government attempted to formulate a particular public policy to protect each party involved in the vertical housing operation. Conducted with qualitative research methods, the objective of this study is to examine the implementation of the DKI Jakarta Governor Regulation Number 132 Year 2018 concerning in the Management of Owned Apartments (Pergub 132/2018).

Abstract
The Surabaya IV Regional Construction Services Center (BJKW IV) is an Organizational Unit under the Ministry of Public Works and Public Housing. One of the main tasks is the management of Non-Tax State Revenues. BJKW IV Surabaya has the assets of the Hall, Mess/Dormitory and Classrooms which can be used for internal activities and leased to private institutions related to construction services. However, the rental rates of the above building assets that are still used Government Regulation Number 38 of 2012 cannot meet operational and maintenance needs. This study aims to establish the latest rental rates that are able to meet operational and maintenance needs. In this paper, the analysis of rental rate determination uses the method of Activity Based Costing (ABC). The results show that the tariff requirements to meet operational and maintenance requirements are as follows: Hall rental rates is 1.15 times the original rate, Mess/Dormitory Rooms rental rates is 2,75 times the original rates, Large Classes rental rate is 2,25 times the original rates and the Small Class Room rental rate is 1,85 times the original rate. Based on the results above, BJKW IV Surabaya needs to consider tariffs for commercialization to the private sector.

Abstract
Technoplex Living Apartment Bandung is one of the buildings using a shear wall that is built in earthquake-prone areas. This study analyzes the CW3 shear wall Type which aims to determine the seismic load plan using spectrum response analysis that is applied and analyzed on the structure of the building so that the horizontal deviation value that will be compared against the value of horizontal deviation that is permitted under SNI 1726 of 2012 is obtained. The results of this study can be concluded that the CW3 shear wall produces the highest horizontal deviation value in the direction of X of 0.032 m greater than the highest horizontal deviation value in the direction Y of 0.0042 m. Because it was analyzed in one direction, namely the X direction with the percentage of seismic load received using an orthogonal system where the X direction building structure received an earthquake load of 100% while the Y direction of 30% from the earthquake load was calculated by the spectrum response analysis method and the resulting horizontal deviation was below the allowable safety margin, the percentage of X direction is 56.7% while Y direction is 92.3%.

Abstract
Abstract. OHS issues in Indonesia are still often overlooked. It appears that the number of work accidents are still high. Therefore, in early 2018 the government has decided to suspend all the elevated construction project in Indonesia including Flyover Project. It cause a negative impact such as casualties, material, time, cost etc. One of the factors that most hinders OHS implementation in the Project from the contractors point of view is the high cost of OHS implementation and the safety cost provided for OHS implementation by the owner are inadequate or even none at all. Safety cost planning can be done accurately if the activities based on Work Breakdown Structure (WBS) on the project can be well defined. The Activity-Based Costing method provides more accurate information especially on complex structures and can provide information on cost items that are ignored in traditional methods. The research methods used are archival analysis, case study, survey, and expert judgement. The research result the safety cost in flyover project that is expected to obtain a decent budget and specifically allocated for the implementation of OHS in flyover projects to improve working safety conditions.

Abstract
Abstract. In the last five years in Indonesia, the toll road construction project has become one of the most massive developments, with 65 toll roads and 4 national roads included in the National Strategic Projects list (PSN). However, along with the increase in construction projects in Indonesia in general the number of work accidents has also increased. in the period of 2017 to 2019, 54.5% of the number of construction accidents came from toll road projects. This results in significant losses such as loss of life, time, cost and so on. Wirahadikusumah (2019), the aspect that can improve working safety conditions is the availability of a decent budget and specifically allocated for the implementation of SMK3 in construction projects. Rzvi and Elnathan (1999), Activity-Based Costing method can provide information on neglected cost items in the construction method. So that OHS cost information on road construction projects can be available accurately starting from defining work activities based on Work Breakdown Structure (WBS). The research method used is archive analysis, surveys involving construction experts, and previous project case studies. This study produces a ratio of OHS costs to contract values in road construction projects so as to improve work safety.

Abstract
Consolidation settlement in clay soils can be predicted by analyzing the consolidation parameters. Consolidation parameters were obtained from the results of a laboratory consolidation test using an Oedometer and Rowe cell. The Rowe cell can measure pore water pressure, soil saturation, and back pressure as a simulation of field condition while the Oedometer cannot. However, there are significant differences between the results of the analysis with the consolidation settlement occurred in the field caused by drainage conditions, the micro characteristics of the soil structure, and the thickness of the soil layer. Therefore, it is necessary to validate the results of settlement in oedometer and Rowe cell consolidation analysis with the value of settlement of experimental results. The method used is a laboratory consolidation test using an Oedometer and Rowe cell as well as a laboratory-scale experimental consolidation test. The results obtain 79% of differences between experimental and Oedometer, while Rowe cell had a difference of 37% from experimental. Based on this, analysis using Rowe cell consolidation parameters can predict a settlement in consolidation in the field more accurately than Oedometer, because it has a smaller difference in value.

Abstract
Reservoir is a water resource facility that has a function as a storage and water provider. The abundant water in the rainy season is accommodated, stored and used appropriately throughout the year. The fact that is happening now as time goes by is that many reservoirs in Indonesia have decreased function and performance. One of them occurs in the Bajulmati Reservoir located in Banyuwangi and Situbondo districts, East Java. The decrease was due to the planning of the reservoir that was not in accordance with the current conditions. This study aims to analyze the Operating Pattern of Bajulmati Reservoir so that the reservoir is expected to provide optimal performance in utilization for irrigation, raw water and Micro Hydro Power Plants. This research was conducted by analyzing data for the availability and utilization of Bajulmati Reservoir water, stretching the discharge of reservoir inflow in the future for 50 years, forming a model with Dynamic Programming and simulation. The first simulation was carried out according to the operation of the current reservoir, which is prioritized for irrigation (factor kT = 100% with differences in how to calculate irrigation water requirements), irrigation water is passed through a turbine (PLTMH). In the second simulation, the reservoir was operated with the fulfillment of irrigation and raw water, a factor of kT> 70% and the Micro Hydro Power was optimized considering the availability of water in the reservoir. The simulation results show the operation of the reservoir in producing electricity on average per year if the turbine must be fully operational and if a turbine with a 20% maximum power already operate with a percentage of the fulfillment of irrigation and raw water (factor kT). From the analysis of income (without taking into account the cost and assuming the provision of irrigation water and raw water are performed simultaneously) are known to be the highest income and lowest income.

Abstract
The activities in the Indonesian construction industry have increased in recent years due to the government-s policy in the acceleration of infrastructure developments. Construction safety is one of the vital aspect on sites, which often times gets overlooked. One of the reasons is the lack of separate budget allocated for the implementation of Occupational Safety and Health Management System (OHSMS) in precast bridge project. In effect, it creates higher rates of accidents, which in turns, project terminated, delay and cut down project profits. The aims of this study are to determine the Work Breakdown Structure (WBS) in precast bridge project, identify potensial hazards, develop safety plans, identify safety cost components, and generate a calculation of safety cost. This research is conducted as a survey research using respondents who are experts in construction safety and descriptive analysis to determines the variables used. A case study approach is used to generate safety cost calculation. This study results are the precast bridges standardized WBS, a safety plan to each hazards and activity, finding the safety costs components based on WBS, and the calculation of safety cost percentage which will improve the OHSMS and reduce the number of accidents in precast bridge projects.

Abstract
Construction Service Unit IV Surabaya is one of the work units of Ministry of Public Works and Housing. This work unit has a workshop and dormitory building as assets, both of which function to support its duties in carrying out construction training. However, the building utilization rate is relatively low, so the building is rarely used (idle) and has not been used to its optimal potential in supporting the function (underutilized). The purpose of this study was to analyze the strategies for workshops and dormitories building utilization to support construction training. The method used in determining the strategy is internal environmental analysis with Resource-Based View (RBV) and external environment analysis with PESTLE analysis. The strategy formulation includes input stage with EFE and IFE Matrix, matching stage with SWOT Matrix, IE Matrix and Grand Strategy Matrix, and decision stage with QSPM. This research has succeeded in getting a strategy that is in accordance with the conditions of the work unit, namely market development strategy, market penetration, and product improvement.

Abstract
Thermal load due to a fire along with wind load is one of the loads which may occur on the building structure. Meanwhile, the planning of buildings in Indonesia generally does not take the load into account. The presence of thermal load can lead into the degradation of structure especially for steel structure which has low resistance to fire. The result of this thermal load is failure which can lead into the collapse of the building. In this study, there will be studied the effect of thermal and wind loads on the response of steel building structure. The structure of the building that will be studied in this research is a fifteen stories building which serves as an office. In the preliminary design stage, there will be determined the dimensions and the profiles of steel which are used for structural elements based on the required codes. Thermal load along with wind load will be assigned on the building structure by considering the degradation of steel properties, the reduction of live load and super imposed dead load, and the speed of extinguishing process. This simulation is divided into three cases which are fast extinguishing, slow extinguishing, and the determination of the critical thermal load. At the stage of preliminary design and fire simulation, structural analysis will be done using the ETABS program. The result of fire simulation shows that the temperature level and the location of the fire will greatly affect the resistance of steel building structure. If the temperature is higher, the stress ratio of structural elements will expand too. In the determination of the critical thermal load, it is obtained that the minimum thermal loads which can cause failure in one major structural element are generally different at the bottom, middle, and top level of stories. In this case study, the highest critical temperature load is on the top level stories.

Abstract
There are a lot of direct methods to estimate bearing capacity of pile foundation using cone penetration test (CPT). Hence, it is interesting to evaluate which method that suitable for a certain condition or specific locations. This paper tries to analyse the results of CPT direct method calculations for the pile foundations that were constructed in Jakarta, Indonesia. The pile capacities are determined using the following methods: Schmertmann, de Ruiter dan Beringen, LCPC, Aoki and De Alencar, Penpile, Price and Wardle, Philipponnat and Wesley. The pile capacities will be compared to the measured pile capacities from static pile load tests,which interpreted by Chin method and Decourt method, and the results from PDA testing. The statistical analyses used in this paper are the best fit line of the predicted pile capacities versus the measured pile capacities, and the mean and standard deviation of the ratio between the predicted pile capacities and the measured pile capacities. In general, the result of the CPT direct methods calculations are mainly underpredicted. Results showed that Philipponnat is the most appropriate method in the studied location with average value of ratio between the predicted pile capacities and the measured pile capacities is roughly 1.03.

Abstract
Fire events reduce the strength of the steel structure on the bridge and can cause collapse which results in losses, so it is necessary to consider the effects of fire when planning construction. Considering that the joints affect the performance of steel structures, the results of research on the performance of steel beams need to be augmented by testing the post-fire girder bridge bolt connection performance. Structural tests will be carried out on six specimens of bridge steel beam elements with high quality bolt connections in the center of the beam with sliding type bolt connections. Two control specimen beams were tested with shear loads without combustion. Two specimens with temperature of 700oC and 900oC with different torque bond variables. From the displacement control test using UTM on six specimens, it will be known the performance of each type of connection by evaluating changes in carrying capacity, stiffness, deflection capacity, ductility, and stress-strain capacity due to the influence of temperature acting during the fire process. The results can prove which type of bolt connection is better for use on bridges with fire risk.

Abstract
Flood problems become a crucial problem in the city of Jakarta. Jati Pinggir - Petamburan area is one of the affected floods. The density of the population and the narrower open land for water absorption causes the accumulation of standing water. The increased flow of water inundation affects channel capacity. For this reason, it is necessary to examine the ability to exist flood control buildings such as drainage canals, reservoirs and pump houses to deal with flooding with a 10-year return flood discharge in Jati Pinggir - Petamburan. Analysis of regional rainfall data, 10-year return period flood discharge, existing channel dimensions, the capacity of the pond and pump needs were used in this study.

Abstract
Delay in construction industry impact the time and cost of project and mostly being the basis of dispute between stakeholders of the project. To reduce the impact, knowing the causal factors and lesson learned from past projects and studies is essential. Through this study, a literature review on the subject of construction delay factors studied in Indonesia, Malaysia, Thailand and Vietnam was undertaken to identify top factors and to determine whether there are special causes referring to this region. A comparison was made to a similar study on developed economies in Europe and North America. The result of the study revealed that the most significant factors causing delays in the Southeast Asia developing countries were related to contractor (material shortages, improper/ ineffective planning, poor site management and supervision, and equipment shortage and failure), and owner-related causes (financial/ payment issue and design change/ variation order). The results of the study support the view that contractors handling projects in developing countries are dealing with the shortages problems, inefficiency/ incompetence of the contractor, and problems caused by clients.

Abstract
Porous asphalt uses open-graded with a higher percentage of coarse aggregate than fine aggregate. Porous asphalt has low stability. One of the ways to used to improve the stability of porous asphalt mixture is adding gilsonite as an additive, which aims to improve the quality of asphalt. The use of concrete waste as coarse aggregate can also increase the stability of the mixture. In this study will use concrete waste as coarse aggregate and adding gilsonite as an additive. The proportions of regular coarse aggregates and concrete wastes are 0/100, 25/75, 50/50, and 100/0. The additive used is gilsonite, with gilsonite variations of 5.5%, 6.5%, 7.5%, and 8.5%. The goal of this step was to obtain the optimum asphalt content, optimum concrete waste proportion and optimum gilsonite content. Once the optimum asphalt content, optimum concrete waste and optimum gilsonite content are determined, the related Marshall characteristics could be determined. Based on the testing result, optimal asphalt content is 5.13%, the proportion of optimum concrete waste is 100%, and optimum gilsonite content is 8.5%. The use of 100% concrete waste and adding Gilsonite additive at ranges 8.5% improves the Marshall characteristic, particularly its stability.

Abstract
Filler is one of the ingredients functioning as a filler of ribs from a paved mixture.. In a flexible pavement structure, the surface layer is the most upper part of the pavement which acts to hold the wheel load and also as a dense layer of water to protect the required road body, with a minimum thickness of 4 cm. This research was conducted by experimental method aiming to know the highest stability value using volcanic ash deposits as a substitute for cement in the filler.The deposits of volcanic ash used are 0%, 25%, 50%, 75% and 100% of the filler weight. The specimen material consists of several types, namely Marshall, PRD, IP, and GMM specimens. Concrete asphalt mixture is designed on the basis of the Marshall method. The results show that the volcanic deposit content is 0% with a stability value of 1133 kg, 15% with 1151 kg stability value, 30% with 1076 kg stability value, 50% with 1056 kg stability balue, 70% with 1048 kg stability value, 85% with 1047 kg stability value and 100% with 1121 kg stability value. From these variations, the highest stability value is found in 15% volcanic ash deposition with 1151kg.

Abstract
The increasing availability of aggregates as road pavement materials and road pavement forming materials are increasingly limited in numbers shown by the dredging of rivers and cliffs in the mountains. Thus, other materials are used, namely concrete waste originating from the residual compressive strength test of concrete as a substitute for coarse aggregate that is obtained easily and cheaply to overcome the increasingly reduced availability of natural aggregates in Indonesia and one of environmental preservation system. The shortage of concrete waste has a high absorption, so to overcome it is needed additional substances in the form of Wetfix-Be. Laboratory-scale experimental testing method is testing Marshall characteristics using the proportion of concrete waste and crushed stone that is 0/100, 40/60, 80/20, 100/0. For Wetfix-Be levels used are 0%, 0.15%, 0.25%, 0.35%, of the weight of asphalt. The results of the study using concrete waste and Wetfix-Be as an aggregate and asphalt mixture can improve the quality of the flexible pavement layers in the AC-WC (Asphalt Concrete Wearing Coarse) mixture so as to reduce waste in the form of concrete residues in Indonesia.
