Abstract

Roads are one element of land transportation which is intended to facilitate the movement of people or goods. If road damage occurs it can have an impact on social conditions, especially land transportation facilities. Many causes of road damage are caused by vehicle loads and vehicle volumes which continue to increase beyond road capacity.   The aim of this research is to determine the types of damage that occur on these road sections, such as potholes, longitudinal cracks, collapse, patching, and loose grain which is damage to the Jendral Sudirman road, Ambon City. Based on the level of damage or the condition of the road that has deteriorated, road damage will be handled according to the PCI method according to the level of road damage on the Jendral Sudirman road section, Ambon City.From the results of calculating the condition of the road pavement on Jalan Jendral Sudirman, Ambon City, a rating of 65% was obtained with the condition (Fair).

Abstract

The Trans Seram road section of Lumoli Village, West Seram Regency has a length of 7,150m and a width of 6m starting from STA 0+000 to STA 7+150. Along the road section there are four landslide points, namely at STA 0+350, STA 1+850, STA 2+600 and STA 3+615. Of the four avalanche points, there are three points that have been handled and the remaining one point has not been handled. The avalanche problem at STA 3+615 - STA 3+650 occurs along 35m with a slope height of 6m already covering the road body ± 4.2m remaining 1.8m. This greatly disrupts the activities of road users because it causes narrowing of the road body and temporary avalanche handling using used asphalt dromes. The purpose of this research is to determine the dimensions and stability of retaining walls against shear, overturning and soil bearing capacity on the Lumoli village trans seram road section. The planning of retaining walls on the trans seram road section of Lumoli village uses a cantilever type with a height of no more than 6-7m as a structure to prevent soil collapse by using rankine theory to calculate lateral soil pressure. The results of the dimensions of the cantilever type retaining wall H = 4m, H1 = 3.52m, H2 = 0.48m, Df = 0.8m, H2 = 16m, H22 = 0.23m, A = 0.66, b = 0.3m, C = 1.18m, D = 0.66m, B = 2.8m. And the results of stability against overturning = 3.027 ≥1.5 Safe, stability against shear = 2.910 ≥1.5 Safe and stability against bearing capacity = 809.045 Kn/m2.

Abstract

Central Maluku Regency is an area prone to earthquakes because it is included in one of the 5th earthquake zone areas in Indonesia, so it is very necessary to analyze the performance of structures against earthquakes. The purpose of this research is to produce the displacement value between floors in the upper structure of the Central Maluku Regency DPRD Building and obtain the performance of the upper structure of the Central Maluku Regency DPRD Building with non-linear static analysis with the help of the SAP2000 v.22 program. This research shows several conclusions.  The displacement value between plants due to the largest X-direction earthquake load is 21.19 mm, and the largest Y-direction displacement is 20.73 mm. Evaluation of structural performance The results of the X-direction review capacity curve show that the building is included in the IO condition, while the Y-direction review provides an overview of the behavior of the structure experiencing elastic, in-elastic conditions and then experiencing collapse shown by the curve with a decrease. In the Y direction, the building is included in the IO condition. The design concept of a strong column weak beam is fulfilled, this is because, in the structural elements of the building, the beam experiences plastic conditions earlier than the column.

Abstract

There are several aspects of project implementation management, such as implementation plans, schedules, and others. The emergence of problems in the implementation management aspect hurts project implementation. Then the alternatives that are usually used to support the acceleration of activities is to increase working hours so that it has an impact on the total project cost. The Madrasah Ibtidaiyah Negeri 5 Maluku Tengah New Classroom Construction Project was chosen for the research study because it experienced delays. The CPM (critical path method) is used to analyze the project implementation time to obtain critical work that has no leeway days to be accelerated. The optimal time and cost are obtained from the Crash Program using the Crashing method by adding working hours to each accelerated critical work. From the acceleration, the cost slope value is obtained. the purpose of this research is to determine what work is critical in the project and also get the results of analyzing the calculation of time and cost of work after being accelerated. The result showed that the total normal project cost budget of Rp 2,891,000,000 with an implementation duration of 120 days, in conditions after crashing with an alternative of adding working hours for two hours obtained a cost of Rp 2,943,185,364 greater than the total project cost budget under normal conditions and a reduction in duration to 110 days or faster than the normal duration. The total cost slope value obtained was Rp 64,231,234.

Abstract

In project implementation, there is often project completion that is not under planning both in terms of cost and time, so to overcome it requires good project management in the form of cost control and good implementation time in order to help the implementation as planned. in the MIN 5 Central Maluku New Classroom Construction Project located in Tulehu Village, Salahutu District, Central Maluku Regency which has a budget of Rp. 2,891,000,000.00 with a planned implementation time of 120 calendar days from June to October 2022 but the realization of the project is late and completed in 161 calendar days. To overcome these problems, the author uses the Result Value method.The Earned Value method is a control method used to control project costs and time in an integrated manner. Project time or schedule control is a process of monitoring the status of project activities to determine the progress or progress of the project. While project cost control is a process of monitoring the status of project costs to find out project costs at the time of the project.From the results of the analysis in the 3rd month, the value of the cost variance (CV) shows the number (-), which means that the cost of project expenses is greater than the budget. While the value (SV) of the schedule variant shows (-), which means the work is carried out later than the work. However, the evaluation in the 4th month seen from the value of the cost variance (CV) shows a number (+), which means that the cost of expenses is smaller than the budget (Rp.2,891,000,000,00) with the actual cost (ACWP) of the 4th month of (Rp.1,775,028,092.00). The profit obtained by the contractor amounted to (Rp.174,661,809). And the time required to complete the project is 5.53 months.

Abstract

Stakes have long been known as a joint tool in wooden construction made using wood that has high shear and bending resistance, because hardwood is starting to be scarce, so this test is carried out to find other alternative materials as a substitute for wooden pegs that have high resistance, knowing how much shear strength is obtained in sago frond pegs, and the influence of pegs with variations in wood thickness on the size of the shear strength. The research method used is experimental, which is an experimental method in which an experiment is carried out to obtain information about something being experimented. This research was carried out in the Laboratory of the Department of Civil Engineering, Ambon State Polytechnic, using sago fronds as a sample in the test. The data collection technique used is experimental on test objects. The results of the shear strength test obtained on the sago frond peg at the base width of 20 mm were obtained that the average shear strength was 40,103 MPa, the width of the 30 mm base was 44,821 MPa and the width of the 40 mm base was 47,652 MPa, so it can be concluded that the shear strength is affected by the size of the support, the larger the base the greater the shear force received.

Abstract

Syaranamual street is situated in Poka Village, Ambon . It is one of the provincial roads affected by landslides due to its location near a fairly high slope/cliff, precisely at Batu Koneng  Fruit Market, Poka Village. The landslide disaster that occurred was due to the influence of bad weather in the form of high-intensity rain accompanied by strong winds that hit Ambon city, so a solution was needed in the form of planning the construction of a retaining wall. The research aims to plan the dimensions of the retaining wall and analyze and determine the safety factor for the stability of the retaining wall in the landslide area on Jl. Syaranamual, Poka Village, Ambon . The method used in this study is by using theory and also empirical formulas according to Rankine about active earth pressure and passive earth pressure on retaining walls and the Terzaghi method regarding soil bearing capacity. The study results show that the planned retaining wall is a gravity retaining wall with height (H) = 4 m, bottom width (B) = 2.4 m, top width (T) = 0.3 m, and Df = 0.5 m. The safety factor obtained from the calculation results is that the wall is stable against the shear force with a value of 2.2 > 1.5 (Safe), the wall is stable against the overturning force with a value of 2.03 > 1.5 (Safe), and the safety factor for the stability of the retaining wall obtained is 3 (Safe).
