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

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).

Abstract

In project implementation, project completion often occurs that is not under planning both in terms of time, cost, and quality, as well as over budget, so to overcome this, good project management is needed in the form of time, cost, and quality control. on the New Classroom Construction Project for Madrasah Tsnawiyah Negeri 6 Central Maluku located in Liang Village, Kec. Salahutu, Kab. Central Maluku which has a budget of Rp. 2,998,745,000.00 with a planned implementation time of 126 calendar days from June to October 2022 but the realization of the project was late and was completed in 168 calendar days. To overcome this problem, the author uses the earned value method. The Earned Value method is a control method used to control project costs and time in an integrated manner. From the results of the last analysis in the 24th week, the work cost index (CPI) < 1, which means that the actual costs (ACWP) incurred were greater than the planned work costs (BCWP) so that the project experienced a cost deviation with a presentation of 0.92%. or 266,915,349.35 from the project budget, while for (SPI) the time performance index in the 18th week is <1, which means the project performance is slower than the planned schedule so that the project experiences a time deviation of 168 working days with an additional 42 working days from the scheduled implementation 126 working days so that the project was completed in the 24th week.
