Construction projects often encounter problems such as changes occurring during implementation. These changes may occur in the early, middle, or late stages of the project. Hanna AS (2002) defines a change or change order (CO) in a construction project as an event leading to a change. In this study, the author uses the SmartPLS 4.0 application for data analysis techniques. SmartPLS 4.0 has an outer model/measurement model and an inner model/structural model to test the degree of validity and reliability of the indicators of the variables used in the study and also to determine the impact of relationships between each variable used in the study. Loading factor values for each indicator exceeded 0.6 and AVE values for each variable exceeded 0.5 in the convergence validity test of this study. For the discriminant validity tests, the cross-loading score and the Fornell-Larcker score meet the SmartPLS 4.0 requirements, and the HTMT score for each variable is less than 0.9. The R² test (r-squared) gave an R² value of ≥ 0.75 (75%). On the other hand, the path coefficient test yields a significance value (P-value) for the effect between variables of 0.05 or less for an alpha value of 5%. It can be said that the variables used in this study are valid and there are strong relationships between the test variables.

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.

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).
