The Ibn Khaldun University Women's Dormitory Building, Bogor (ASPIKA) is a building that functions as a temporary residence for female students. The ASPIKA Building was established 13 years ago, this has resulted in several building components and structures experiencing some damage which resulted in the function of the ASPIKA Building decreasing, so an assessment of the reliability level of the building is needed. Aspects used in the assessment of the reliability of the ASPIKA Building based on the proper function of the building include aspects of architecture, structure, utility and fire protection, accessibility, and building layout taking into account the applicable SNI standards. The method used is descriptive quantitative as well as survey data of the existing building by the Minister of Public Works No. 2/PRT/M/2006 concerning Guidelines for Building Technical Requirements. The results showed that the percentage value of the building on the architectural component aspect was 95.50%, indicating the building is in reliable condition. The percentage value on the structural component aspect of the building is 96.56%, indicating that the building is still reliable. The percentage of utility and fire protection components has a value of 65% indicating that the component aspects of the building are not reliable. Unreliable factors in utility and fire protection components are influenced by an inadequate fire prevention system so more attention must be paid to these aspects. Components in the accessibility aspect get a percentage of 65%, meaning that they are less reliable, where this value is influenced by the limited access of people with disabilities to reach areas on each floor of the building. The building layout and the environment get a 100% percentage which identifies the building layout as reliable based on the documents on the ASPIKA Building. The total value of the reliability level of ASPIKA Buildings obtained is 79.41% categorized as "Less Reliable" (reliable category is > 95%), this is influenced by the fire protection component by 65% and the accessibility component by 65%. The solution that can be done by the university is to repair and procure facilities on the fire protection system and provide accessibility facilities that can make it easier for people with disabilities.

Bogor City is located between 106,480 E and 6,360 S and has an average altitude of at least 190 m, a maximum of 350 m, slope between 0.3%, 4-15%, 16-30% and above 40% with a distance of approximately 60 km from the capital, surrounded by Mount Salak, Mount Pangrango and Mount Gede. Bogor City has annual rainfall between 3500-4000 mm with an area of 4,992.30 Ha, between 4000-4500 mm with an area of 6,424.65 Ha, and between 4500-5000 mm with an area of 433.05 Ha mainly in December to January. (kotabogor.go.id). On 27 April 2019, landslides occurred due to heavy rain in Perumahan Curug Residence Griya Elok Jalan Parvi Bojong Neros RT. 03/ 07, Curug Village, West Bogor District, Bogor City. It is necessary to plan the retaining wall to mitigate the impacts of the landslide disaster. The access road in Curug Residence is an asphalt road with a width of 2.5 m, this causes only small vehicles to be able to pass in the area. In consideration of the narrow access road, heavy equipment cannot enter the Curug Residence landslide location, in order to deal with landslides, a gabion-type retaining wall will be applied. The gabion retaining wall is more efficient and practical with narrow road access because it can be done directly on site and does not require any heavy equipments. The results of the analysis of gabion retaining walls can be concluded as follows, the dimensions of the gabion retaining wall construction are 9.5 meters high, the width of the foot slab is 1.58 meters, and the thickness of the wall top section slab is 0.79 meters. After the calculation, the result of stability factor to shear is 3,624 > 1,5 and stability to bolsters is 5,858 > 1,5. Then it can be concluded that the gabion retaining wall is safe against danger of shear, bolsters and soil bearing capacity. The construction cost is Rp2.735.000.000,- and requires 127 days or 3 months and 1 week of construction work.

In October 2022, there was a landslide in Tanah Sareal Subdistrict at Cipakancilan River, Sukaresmi Village, Bogor City. The location of the landslide occurred on the edge of the road adjacent to the Cipakancilan river, the road is an access road that connects the Regency area and the Bogor City area. The length of the landslide that occurred was 30 meters and 11.5 meters high from the Cipakancilan river water level. The construction of a retaining wall (DPT) is the right solution to maintain slope stability, namely rolling stability, shear stability and soil bearing capacity stability to restore stable slope conditions to hold the road body which can be reused as an access road for residents. This research started with an initial stage in the form of a field survey, then continued with a geotechnical investigation to determine the characteristics of the soil that experienced landslides. Based on the results of the research, it was found that the design of retaining walls of gravity type and cantilever type was analyzed using the Coulomb method for calculating lateral soil pressure and Mayerhof for calculating the stability of soil bearing capacity. For construction costs from the calculation of the cost budget plan, the results obtained for the gravity type retaining wall amounted to Rp. 1,229,923,600 (one billion two hundred twenty nine million nine hundred twenty three thousand rupiah), while the cantilever type retaining wall amounted to Rp. 1,620,913,000. 1,620,913,000 (one billion six hundred twenty million nine hundred thirteen thousand rupiah), the time of the planned implementation of gravity retaining wall work for 2.5 months or 75 calendar days, the time of the planned implementation of cantilever retaining wall work for 3 months or 90 calendar days.
