Indonesia is in an area with quite high earthquake activity because this high level of activity can damage important facilities and infrastructure. After the earthquake on September 26 2019 with a magnitude of 68, it caused shaking in several areas in Maluku. The epicenter of the earthquake was located on Seram Island, causing a lot of damage to both infrastructures. Residents' houses and worship facilities, including the GPM Sola Suptura Banda Congregational Church Building, suffered quite severe damage, both structural and non-structural. The aim of writing this thesis is to obtain identification results based on the level of damage that occurred. In this research, a survey and direct inspection were carried out which will be analyzed or processed based on an assessment of the level of damage that occurred at the location. From the identification results, the overall level of damage to the building reached 74%, which means the condition of the building was completely damaged. The earthquake factors classified according to each structural component are structural damage to columns by 5%, beams by 16% and also damage to construction, roof by 4%, ceiling by 12%, walls by 19%, utilities by 7%, sexta finishing of 5%, which results in a weight percentage of the entire building being 74%, which means the condition of the building is in the Total Damaged (RT) category because it is 65%, according to Minister of Public Works Regulation No. 24/PRT/M/2008.

Bricks are a building material that has long been known and used by people in both rural and urban areas and has the same function, namely as a construction material. Bricks are used for civil engineering applications such as walls and residential buildings, fences and also channels. Bricks are made from clay which are made using a simple mold made of wood. After being molded, the bricks are dried in the sun to dry. Once dry, the bricks are arranged neatly and burned at a fairly high fire temperature. This burning process can cause the bricks to become hard. This research was carried out to determine the quality of bricks in two villages, namely Hatu village and Laha village using physical and mechanical properties testing on printed brick samples. Based on the results of testing the physical properties in Hatu village, it was found that the specific gravity was 1.596, the bulk density was 14.7 gr, the porosity was 37.8% and in the Laha village the specific gravity was 1.811, 13.6 gr and 42.4%. Meanwhile, the mechanical test results for the bottom sample in Hatu village were 27.31 kg/cm2 and the bottom sample was 40.10 kg/cm2 and the results in the bottom sample village were 19.16 kg/cm2 and the results for the top sample were 18.02 kg/cm2.

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).

Bridges are one of the important infrastructures in transportation that have a vital role in connecting one place to another. Bridges are also one of the important elements in the development of a country because they can support economic growth and community welfare. However, in the management and maintenance of bridges, there are often various challenges faced, such as structural wear problems, declining material strength, and damage due to natural factors such as earthquakes and floods. The Bridge Management System (BMS) and Bridge Condition Rating (BCR) methods are used in this study to identify and provide an assessment of the bridge condition value, the results of the bridge assessment will be used to determine the maintenance procedures that can be carried out on the bridge. From the results of the inspection in the field, there were several damages such as damaged or missing components, changes in the shape of components, concrete loss, accumulated garbage, cracks and rough or perforated surfaces in the surface layer, cracks in the bridge expansion joints, as well as a decrease in paint and glavanis. From the results of the examination and assessment using two methods. The BMS method is known to have the general condition value of the Wai Welinaha I bridge with a condition value of 0 or in a state (Good), and the damage codes on the Wai Welinaha I bridge are 806, 204, 204, 202, and 202. In the BCR method, the proposed inspection of the Wai Welinaha I bridge is routine and periodic maintenance. From the results of the current review that has been carried out, it can be concluded that the level of damage to the bridge has increased. With some areas damaged.

The Wailola Besar Bridge, which is located in Bula District, East Seram Regency, has a Warren truss type frame structure. However, unlike the truss used on other bridges, the truss on the Wailola Besar bridge has a larger size than the others. Because the span of the Wailola Besar bridge is 80 m, while the span of other bridges using the Warren truss type is a maximum of 60 m. The larger size than the other trusses makes the Wailola Besar bridge have a different truss from other trusses. The length of each horizontal bar is 6.65 m, while the maximum length for other bridges is 5 m. Then the purpose of this study is to determine whether the truss structure of the Wailola Besar bridge is capable of carrying the loads acting on the bridge, the method used is with the help of the SAP-2000 program to determine the truss forces then controlled with allowable voltage. In order to know whether the structure is able to withstand the forces acting. From the results of calculations with the help of SAP-2000 the rod forces acting on the largest truss structure are 11066.881 KN at constant loading and 12222.547 KN at temporary loading and the stress that occurs is 1742.82 Kg/〖cm〗^2. at constant loading and 1924.81 Kg/〖cm〗^2. The stress that occurs in the truss does not exceed the allowable stress.
