Abstract

The development project of the Masela Block Supporting Intergrated Laboratory, Pattimura University was intended to be the object of this research because it was based on the problems that occurred in the project, namely delays. Based on secondary data obtained from the project, the budget plan (RAB) and time schedule are used the duration and normal costs of the project. Then crashing program method and the fast-track method are applied to reduce the duration and find out the total cost needed so that the project can run properly as the planned target time and does not experience delays.  Crashing and fast-track methods are methods use to accelerate the execution time in contruction projects. Although these two methods can clearly reduce the application of these two methods on project implementation costs.  From the analysis result carried out on structural work that crosses the critical path, it is obvious that the crashing time method is reduced by 17% or 38 days and the resulting cost overrun is 0.02% or IDR 10,615,733.38, while for the fast-track method reduced work duration is around 18% or 41 days where the project cost is also reduced by 1.89% or IDR 774,757,772.32 from the normal duration which should be 225 days at a cos of IDR 62,257,321,000.00.

Abstract

The Lokki – Iha Kulur Road Section is the main transportation route that connects villages in Huamual District, West Seram District. This area often experiences inundation and runoff caused by drainage that cannot accommodate flood discharge and improper drainage elevation systems. To overcome this problem, it is necessary to review the drainage system. The research method used is the method of data collection and analysis. The data used are primary data and secondary data and then analyzed using rational methods based on hydrological analysis and hydraulics analysis and evaluated based on the magnitude of the discharge of the existing canal with the magnitude of the planned discharge. Based on the calculation results for a 5-year return period, a planned rainfall of 632.812 mm is obtained, with a population growth percentage of 1.2% per year so the population of Luhu Village in 2026 is 34,251 people. From the results of the analysis, it was found that the amount of planned discharge entering the Lokki – Iha Kulur Road drainage was 0.15038 m3/s for drainage 1 and 0.14377 m3/s for drainage 2. Meanwhile, the discharge for the Lokki – Iha Kulur Road drainage for drainage 1 is 0.14229 m3/sec and for the drainage 2 is  0.14377 m3/sec. So it was found that the drainage was not able to accommodate the planned flood discharge so it was necessary to re-plan the drainage dimensions so that the problems of inundation and runoff could be overcome.

Abstract

The truss structure of the bridge is formed from several arrangement of rod elements which are connected by joint joints at the point of connection. The actual conditions in the field on the main frame structure of the Way Mamua bridge, Leihitu District, Central Maluku Regency, have dimensions of the steel cross-section that are quite large and not optimal, so that in this present study aims to analyze the rod forces of the Way Mamua Bridge structure and optimize the cross-sectional dimensions of the Way Mamua Bridge trunk frame. The methods used in this study are the ritter and cremona methods, as well as cross-sectional optimization simulations using the help of the SAP2000 program. Loading Standards for Bridges based on SNI 1725:2016 and Steel Structure Planning Standards for Bridges are used by SK regulations. SNI T-03-2005. Based on the results analysis of the rod forces of the Way Mamua Bridge structure, a minimum bar force was obtained for the upper horizontal bar, the lower horizontal bar and the diagonal bar totaling 2 bars. The maximum bar force for the upper horizontal bar is 1 bar, while the lower horizontal bar and diagonal bar are 2 bars with accepted forces namely compressive and tensile forces. The optimization results obtained an increase in the percentage of cross-sectional dimensions to the cross-sectional area for the upper horizontal bar by 2%, the lower horizontal bar and diagonal bar experienced a percentage reduction of 64% and 54% of the cross-sectional dimensions under actual conditions in the field. From the optimization results, the voltage ratio is not > 1 so that it can be concluded that the bridge bar truss structure is still in safe condition.

Abstract

On the A. Y. Patty road the length of the road is ± 425 meters, the width of the road is 8.75 meters and the road median is 1.9 meters. For this road, the availability of insufficient parking space makes road users misuse road sections that should not be used as parking lots. This is caused by misuse of land use because there are many along this road. So it is necessary to examine the analysis to detemine the performance of traffic and parking space available for four-wheelend vehicles. What are the characteristics of the parking space and the capacity of the available parking spaces on the A. Y. Patty road in Ambon City, which are still sufficient to accommodate four-wheeled vehicles? The method used is the direct approach method, where the calculation of parking space capacity is by calculating directly used for parking SRP Passenger cars score I. The highest parking volume was on Monday 12 September 2022 as many as 639 vehicles with the highest accumulation of 78 vehicles. The capacity of the parking space for 78 vehicles is 969,54 which is smaller than the available land which is 1.305,158, which means it still fulfills or accommodates parked vehicles.

Abstract

The construction of the Waiheru Ambon Hajj Embarkment Transit Building was intended to be the object of this study because it was based on the background that occurred in the project, namely delays. Based on secondary data obtained from the project, the Budget Plan (RAB) and Time Schedule are used as project’s duration and normal costs of the project. Then the time cost trade off method is applied which aims to be able to reduce the duration and find out the total cost needed so that the project can reach the planned time target so as not to experience delays. Dimyati, H (2014) explained that there are two reasons why acceleration of construction of construction projects is carried out. First, because off the desire of the owner so that the project can be completed before the deadline for project completion. Second, because in the implementation of the project there is a delay in time or progress, the acceleration must be carried out.This is where the importance of a plan that must be prepared carefully so that cosis that will have an impact on acceleration the project can be controlled properly. Time acceleration in this project, using the Time Cost Trade Off  Method with the principle of increasing overtime working hours. After accelerating with the addition of 3 hours, it could save time by 0.11% where the project cost is reduced by around 0.003%. Meanwhile, the addition of 2 hours could save time by 0.10% where the project cost is also reduced by around 0.003%. While the optimal duration and optimal costs were known in the alternative addition of 3 hours of overtime obtained 94 working days at a cost of IDR 27,388,709,338.20. Meanwhile, in addition to 2 hours of overtime, 95 working days were obtained at a cost of IDR 27,388,026,130.23.

Abstract

Retaining walls serve the purpose of withstanding lateral pressure from the soil behind them. This construction can be considered as an alternative for addressing potential landslides along the embankment of Hutumuri village road. The aim of this research is to plan a retaining wall as one of the reinforcement alternatives for the embankment along the section of Hutumuri road from Station (STA) 1+200 to 1+270. The planning of the retaining wall along this road section begins with a soil stability analysis using the simple slice method. Subsequently, employing the Terzaghi method, the stability of the wall against soil pressure behind it is analyzed to prevent displacement and potential collapse during the construction of the retaining wall. Utilizing the Simple Slice method and Rankine's theory to assess the slope conditions and the construction of the retaining wall along Hutumuri road section, values for the slope safety factor are obtained. In the unsafe condition, the slope safety factor is less than 1.2, indicating the need for an alternative slope reinforcement, such as a retaining wall. The analysis results for the stability of the Counterfort-type retaining wall indicate that it does not meet the requirements. This is due to the fact that, in section I, the soil bearing capacity safety factor (FS) is 2.454, where the value of FS is less than the recommended value of 3, signaling the need for further consideration and potential adjustments in the design.
