Abstract
The timber bridge design although economical, often has difficulty producing enough rigidity so that a solution is needed to solve it. The use of CFRP (Carbon Fiber Reinforced Polymer) as a reinforcement of structural elements if properly designed and implemented can produce an effective and efficient composite structure. The experimental study aims to analyze the strength, stiffness and ductility of flexural strengthening composite bridge glued laminated timber beams-concrete plates using CFRP layers. The dimensions of the composite glued laminated timber beams 100/180 mm and concrete plate 75/300 mm with a length of 2,480 mm. The number of specimens is 3 composite glued laminated timber beams-concrete plate consisting of 1 test beam without CFRP reinforcement, 1 test beam with one layer CFRP reinforcement, and 1 test beam with three layer CFRP reinforcement. Experimental testing of flexural loads is done with two load points where each load is placed at 1/3 span length. The test results show that the strength of composite laminated wood beams glued - concrete plates BN; BL-1; BL-2 in a row 81.32; 82.82; 82.32 kN/mm; stiffness in a row 7.50; 8.22; 6.32 kN/mm and successive ductility of 16.70; 28.80; 20.20.

Abstract
Abstract Groundsill is a structure in the form of a weir that is built across the river which aims to reduce the speed of the current and increase the depositional discharge in the downstream part of the bridge pole structure. Supercritical flow and sand mining at downstream of the bridge can endanger the pillar. Scouring around the bridge pillars can endanger the girder which of course endangers the bridge as a whole. The aims of this study were to analyze the stability of the Groundsill Bridge in the Garang River channel on the force of rolling, sliding, eccentricity, carrying capacity of the soil, and piping. This research uses survey method. Data collection methods used were observation and secondary data. Analysis of the data used were (1) rainfall design of 50 years return period; (2) design flood discharge with a 50 year return period; (3) the forces acting on the groundsill, and (3) the groundsill stability. The results of the study indicate that: (1) the groundsill were safe against rolling forces under normal flow and flood flow conditions; (2) groundsill was safe against shear forces under normal flow and unsafe during flood flow conditions; (3) groundsill was safe against eccentricity in normal flow conditions and unsafe in flood flow conditions; (4) the carrying capacity of the groundsill subgrade were safe against forces that occur during normal conditions and unsafe during flood conditions; and (5) groundsill was safe against piping under normal flow and flood flow conditions. The recommendation that can be submitted was the groundsill of the bridge in the Garang River channel should be equipped with energy dissipation, besides that the dimensions of the groundsill body are enlarged.

Abstract
The purpose of competency certification can be seen from two complementary aspects, namely to assess a persons ability and expertise in his profession and come out to give confidence to the user that the competence of labour fulfills the requirements in carrying out the task. However, the number of construction labour certified is only about 3% of all construction labour in Indonesia. This study aims to identifying inhibiting factors of competency certification in the perspective of construction labour, especially skilled labour. This study uses a quantitative model with descriptive analysis. This research was conducted on skilled labour in three high-level building projects. The research design used in the form of surveys with data collection methods through questionnaires, observation, and literature study. The results of this study indicate that the factors that hinder skilled labour in obtaining competency certification are 1) Complexity of the implementation of competency certification, 2) The high cost of competency certification, 3) There is no difference in certified labour wages, 4) The certificate does not guarantee quality work

Abstract
Cilember river flows from North to South of Cimahi and crosses PURBALEUNYI Toll Road in downstream. Therefore normalization of Cilember river Cimahi can impact the PURBALEUNYI Toll road. Hydraulic simulation carried out to determine the impact and formulate the mitigations alternatives. The study was conducted based on Detail Engineering Design Data for Cilember Normalisation Program prepared by Citarum River Authority as a base data. Two-dimensional HEC-RAS model was used to simulate the impact of the river normalization program. The model also used to evaluate the alternatives (detention pond, diversion of flows) to minimize the impact of the Cilember normalization program to PURBALEUNYI Toll road. Applying 10 year return period and HEC-RAS simulation, with an existing condition, 26 505 sqm area is inundated mostly in the North area of Toll Roads. After the normalization program, the inundation area shifts to the south area, including Toll road. The further simulation shows that normalization of the river can reduce inundation area to 7 993 sqm. Simulation of combination between detention pond and diverting the excess flow of Cilember to Kali Malang inundated area occurs, but it does not affect the toll road.

Abstract
Traffic movements in the city of Jakarta is linked to the Jakarta Outer Ring Road (JORR) Toll Road. This road network has a high traffic volume because it is integrated with other toll roads that connect between an other cities of Jakarta. The condition of roads heavy traffic volume in the event of road rehabilitations will cause travel obstacles starting from increasing travel time to the long delay in traffic flow at the window time. The travel delay caused losses to road users. Road management must make attention to the impact of the zone rehabilitation to losses time by road users, especially on toll roads. This study analysis the impact of changes in speed in the work zone with short, medium and long work areas. From these 3 types, it can be seen the costs by road users due to the travel time. Traffic surveys have been carried out on the Jakarta Outer Ring Road Toll Road (JORR) section S using the roadpod metrocount tool. This tool can calculate the decrease in speed along with the volume of traffic in the three locations of the work zone. Loss of road users due to travel delay is calculated from vehicle operating costs. The results of this study are known to increase vehicle operation costs by 20% to 40% due to a decrease in speed caused by work zone. The results of this study are expected to be make consideration of road operators in determining the time in choosing of rehabilitation by minimizing the losses of time from the road users.

Abstract
Comfort is one indicator in the performance of building maintenance. This performance can be achieved by carrying out maintenance work on the building architecture components. The maintenance of government green buildings in Indonesia has not been done in an optimum manner due to constraints in maintenance work to government green buildings such as non-digitized data, poorly documented data, substandard maintenance work, and poor or slow identification of damages. Impacts resulted from the poorly maintained building are the increasing operational cost and ineffective maintenance work done to the building. The aim of this study is to increase the comfort of maintenance performance of the architectural component of government green building, especially the wall work package. The case study taken is the Ministry of Public Works and Public Housing Building which is considered as a representation of government green building in Indonesia. The method used are literature research, case study, and survey. The result of this research is the information system development using Building Information Modelling (BIM) integrated into building maintenance systems such as Work Breakdown Structure (WBS), SOP, and building maintenance guidelines for architectural components.

Abstract
Buildings suffer deterioration and function failures during its lifecycle even for landscape and housekeeping components in government buildings. Maintenance includes cleaning, inspecting, repairing, and replacing can provide buildings to maximize the utilities of the building-s lifecycle. Corrective maintenance is the most used maintenance method in Indonesia although there are more than just corrective. Other method that is commonly used is preventive maintenance or an activity to prevent any occurrences of building failures without repairing nor replacing any components throughout its lifecycle. Work breakdown structure (WBS) is an effective method to define preventive maintenance activities. However, in Indonesia there is still lack of preventive maintenance based on WBS activities guidebook and preventive maintenance policies. Therefore, the purpose of this study is to develop a guidebook of preventive maintenance landscape and housekeeping activities based on WBS to improve maintenance performance. Method of the research is activities defined from policies, literature studies, and case studies drawn into WBS and validated by maintenance expertise. Experts validate the preventive maintenance activities using questionnaires and provide any maintenance performance improvements after using the guidebook. Result of the research is that landscape and housekeeping preventive maintenance activities guidebook based on WBS improve government buildings maintenance performance.

Abstract
The availability of decent drinking water is one indicator of the welfare of the Indonesian people as stated in the universal access target of 100% drinking water service in 2019. The Central Government through the Provincial Water Supply Working Unit assists with WSS Infrastructure Development Programs as a stimulant for Local Governments in meeting drinking water service targets. However, the limitations of the APBN budget have resulted in the need to prioritize the selection of the programs. The program selection method was prepared by identifying the existing conditions and evaluating the functioning of assets in each district. The priority sequence of the program was carried out by the Multi-Criteria Analysis (MCA) approach. Determination of priority criteria based on Strategic Policy for WSS Development and WSS Evaluation Guidelines. The priority sequence is the result of a calculation between the weighting of district criteria that carried out by the Provincial Working Unit, and the WSS unit by the Provincial Working Unit and district stakeholders with Borda analysis method. The application of this method resulted in a sequence of priority programs which could be a recommendation for the Provincial Water Working Unit to determine the selection of WSS Infrastructure Development Programs.

Abstract
In seeing the threat of a disaster, the community must have the capability to respond. Disaster risk increases for those who do not prepare themselves for the possibility of a disaster. The purpose of this study is to make a model of harmony of human interaction with the environment in which they live. People living in disaster-prone areas must have an awareness of behavior that can increase community resilience to disasters. The ecological approach can be used to see the interaction of the community with its physical environment. The data in this study were obtained by observation and in-depth interviews with residents living along the banks of the Cimanuk river in Garut City District and reinforced from literature studies. Respondents were selected by community random sampling on the banks of the Cimanuk river which was affected by banjir bandang in 2015. The results of the interviews were analyzed in a qualitative descriptive manner. Physical environmental factors that shape the behavior of community adaptation are land characteristics, rainfall, river border conditions. Community behavior in dealing with disaster risk is determined by the perception of self-determination that shape attitude or attitude is an awareness of the safety of life and property. In addition, there are also social norms or subjective norms that will strengthen peoples attitudes in disaster response efforts, namely religious norms and basic knowledge about the environment. Supporting facilities in the form of physical infrastructure, support of financial resources and institutions as a place to support community interaction in responding to the potential for flood disasters in their residential environments are also a necessity in building disaster response communities. community behavior in preparing themselves for the risk of disasters that arise.

Abstract
Moment resistance of bamboo lamination joint is semi-empirically analyzed by considering the experimental results of various punched plate connector-bolt connections and the energy conservation principle. Laminated bamboo is a product that can act as substitution material of timber. In the analysis, experimental load-slip response plate connector-bolt connection is approximated by exponential and bi-linear models. Verification of the proposed models is carried out through full scale test of semi-rigid joints that monotonically loaded by a pure moment. Four-point bending test was applied on beam moment connection of laminated bamboo structure with plate connector 8 mm thick and 12.2 mm diameter bolts. Bamboo specimens of Petung, split dimension 5×20 mm2, cold pressure 1.5-2.0 MPa, of diameter with pre-stressed bolts of 0.5 MPa-1,00 MPa and two various plate connector fasteners are implemented in both laminated bamboo-steel-to-laminated bamboo connections. Experimental results show punched plate connector fasteners that have long distance along the grain between bolts gives high moment capacity, high ductility, and high rotational stiffness. Laminated bamboo-punched plate-to-laminated bamboo connections have higher moment resistance and higher ultimate joint rotation than laminated bamboo-steel-to-laminated bamboo. Punched plate connector fasteners gave contribution higher friction than steel connector. It indicated that the punched plate connector contributed greater dissipation energy in this connection.

Abstract
The Ancam Port is planned to be a roll on - roll off ship. That is why the Ancam port is equipped with a moveable bridge to anticipate tides. The Moveable Bridge structure is a steel frame bridge with a length of 35,740 meters with one joint and another that can move vertically. This vertical free movement is accommodated by the pontoon but cannot deform in a horizontal plane in the direction of the bridge extending, causing damage to the connection between the pier and the moveable bridge. Tidal river conditions cause the pontoon to move vertically. Under the pontoon there are indications of piles emerging from the riverbed and recurring collisions occur due to tides. This causes leakage so that water enters and causes an imbalance from the pontoon and a collapse of the Moveable Bridge occurs. The movable bridge analysis method is carried out using SAP 2000 software. Based on the analysis of the collapse the moveable bridge is able to withstand the planned load on the condition that the pontoon has to function properly. The solution to re-enable the moveable bridge is to use a geofoam-type styrofoam pontoon wrapped in steel plates.

Abstract
This study aims to determine factors influencing performance assessment of road infrastructure and design proposals for non-toll road performance assessment models. As of now, there has been a performance assessment of road infrastructure, but not yet implemented consistently. It also still needs some improvement by using variables and other variable indicators that have not been used, especially for roads that have been built, operated and maintained. The design of the road infrastructure performance assessment model is done by selecting variable indicators based on literature reviews and expert interviews. Then filtering out variables using relative important index (RII) and weighting variables using pairwise comparisons. As a model validation, the project data for several national road segments in East Java were made as case studies, thus the results were represented in the form of web spiders for an easier interpretation. The model simulation results show that roads in Indonesia are already good in technical and economical aspects, but still need improvement on social, environmental and management aspects. This model can be used as one of the basic considerations for improvements in enhancement of road performance in Indonesia.

Abstract
The work is related to the Ph.D. subject of the first author on the analysis and design of shallow foundation systems in the context of earthquake resistant constructions in Indonesia. We focus here on a particular system called SNSF (Spider Net System Footing) that has been proposed and successfully used for around 10 years. This paper deals with the analysis of a unit cell of SNSF consisting of an assemblage of concrete vertical ribs and horizontal plate subjected to a central loading. We propose a geometrical 3D model and analyses based on 3D solid and shell elements for a detailed static analysis of the structure under central load or under self-weight. We also report some results considering the soil structure interaction, assuming linear elastic properties of the soil

Pedestrian pathways are important to support population circulation while the green lane functions to beautify the city and maintain air quality in cities. Nevertheless, the condition of pedestrian and green lanes in urban areas is often not well maintained so that their utilization is not optimal. This can be seen from the improper use of pedestrian paths, damage to supporting facilities and the death of plants planted in the green lane. This study identified the characteristics of pedestrian paths and green lanes in the center of Garut and evaluated the use of pedestrian paths and green lanes in cities. The method used is descriptive qualitative analysis. The perception of the community of pedestrian users was analyzed from the results of the questionnaire. Responden was chosen randomly from pedestrian and green lane users along Ahmad Yani road which is the center of Garut. The condition of the pedestrian path along the Ahmad Yani road from the Asian crossing to the Holy Bunderan was damaged in several points so that it disturbed the comfort of pedestrians. Circulation of pedestrians is also disturbed because some pedestrian spaces are actually used by street vendors to sell. The pedestrian facilities along Ahmad Yani Road are still incomplete and some of them are in damaged condition. Facilities that are damaged and not as needed are benches, lack of trash bins and non-lit lighting. Plants in open space which is a green path are in poorly maintained condition and even many die. Community perceptions of the importance of the existence of pedestrian lanes and green lanes also influence the awareness of the user community to help maintain and maintain pedestrian paths and green lanes in urban cities.

Abstract
In order to maintain food security in Indonesia it is very necessary to organize the provision of irrigation water. Current surface water discharge conditions have decreased compared to 10 years ago so that there really must be efficient and wise efforts in the provision of irrigation water in paddy fields. Many efforts to increase the productivity of paddy fields and one of them is to optimize paddy fields area and reset cropping patterns in the paddy fields. In the initial stage of this study an analysis of the availability of surface water discharge was then analyzed for irrigation water requirements that could be given to each paddy field in accordance with a predetermined cropping pattern. Then a land area simulation is carried out to obtain the most optimal land area. This simulation is carried out in the conditions of the wet season, the normal season and the dry season. Simulations are carried out with various cropping patterns including rice and secondary crops. Simulation results show that the largest area that produce maximum production in the wet season is 11285 ha, in the normal season is 9436.22 ha and in the dry season is 5944.87 ha.

Abstract
The performance of the modified asphalt concrete pavement structure is done because of the increasing traffic load that occurs along with population growth. The study is needed to review the pavement structure whether it is still able to withstand the load or not at all. An Evaluation was carried out using Falling Weight Deflectometer (FWD) field data to obtain deflection data. Laboratory testing of UMATTA used modified asphalt mixture using Polyethylene Terephthalate (PET) type plastic bottle waste to obtain the relative strength coefficient value as an application combined with secondary data from average daily traffic data on the roads of the Batas Medan City– Batas Lubuk Pakam City. Structural analysis shows that the entire segment requires an added layer with the thickness that is different due to the segmentation performed. This study to maintain the required service level, namely SCI>1, the pavement must receive periodic maintenance and routine maintenance. elated to using asphalt modification using PET will produce a lower pavement thickness of 11 cm compared to the pavement thickness by the 2017 Pavement Design Manual standard of 16 cm.

Abstract
Ashpalt Concrete is a layer on a pavement structure consisting of hard asphalt mixture and aggregate, mixed anda spread in hot conditions and compressed at a certain temperature. Asphalt concrete as a wear layer, known as the Asphalt Concrete-Wearing Course (AC-WC) with a minimum nominal thickness of 4.0 cm. However, the use of AC-WC layers in the pavement structure is often faced with problems of performance degradation due to the development of various types of damage during the service life one of them is a result of the effect of water. In general, water has a negative effect on road pavement construction. Standing water can be caused by high rainfall, poor drainage systems, high groundwater levels, and water runoff. The method used in this research is laboratory-scale experimental methods. Tests carried out in this research encompasses testing the characteristics of materials and testing the characteristics of three types of water. Furthermore, Marshall testing of asphalt mixture that was immersed in three types of water. The Asphalt Level of Oil used is a variation of 4%, 4.5%,5%, 5.5% ,6% ,6.5 %,7%. The OBC value is determined by using the Arrow Range method of the existing Marshall parameter, obtained by the OBC value of 6.15%. This research aims to look at the performance of the physical and mechanical properties of testing Marshall characteristics on a mixture of asphalt pen 60/70 wear layer (AC-WC) on the duration of water immersion from three different types of water. The specimen was carried out immersion testing from three types of water, namely clean water, brown flood water and black air with 30 minute immersion standards with variations of 1 day, 7 days, 14 days, 21 days and 30 days. The results of the study of the typical properties of the AC-WC layer questioned a decrease in density from the initial conditions to the 30 day of immersion. The results obtained were 0.64% for clean immersion water, 0.61% for brown flood water and 0.70% for black flood water. Whereas for VIM values on each specimen for clean air immersion is 43.24%, brown flood water is 45.04% and black water is 44.11%. From the immersion duration, the VIM value on immersion of the clean water still met the criteria, whereas for brown and black flood water at the immersion 7 days to 30 days it did not meet the required criteria. For VFB values, the duration of immersion for 1 month flooded brown water and black flood water below the value of 65%. For VMA values all of specimens and immersion duration still meet standard the value spesification 15% . For the mechanical stability properties of Marshall the AC-WC layer of all specimens still meet the criteria, but the greatest decrease in value occurs in the black flood water immersion specimens of 32.1% in the 30-day immersion from the initial conditions. For the viscous properties shown on the value of flow obtained. The value of flow on immersion 1 day to 30 days did not entered the required criteria. Whereas

Abstract
Steel is the main material used as reinforcement in reinforced concrete structures. The number of steel used every year continues to increase, the increase has an effect on the availability of the main raw materials of steel, namely iron ore which is a non renewable resources. Therefore, an alternative steel replacement material is needed. Bamboo is one of an alternative chosen as a substitute for reinforcing steel in reinforced concrete structures. In this research, we will use Petung bamboo strips which are anchored using screw nails as flexural reinforcement in concrete beams. This research aims to analyze the behavior of load and deflection relationships in the flexural capacity of bamboo reinforced concrete beams against steel reinforced concrete beams. There are 6 beams used as specimens, 2 bamboo reinforced concrete beams with 1 cm long screw nails, 2 bamboo reinforcing beams with 2 cm long screw nails, and 2 beam with 12 mm steel reinforcement as control beam. The results of the flexural strength of bamboo reinforced concrete with long screw nails 1 cm and 2 cm beam were 44.32 kN and 46.98 kN or 48.64% and 51.56% compared to steel reinforced concrete beams with flexural strength of 91.10 kN.
