landslide disaster. Based on this fact, a method is needed to predict the range of landslides to minimize the impact of disaster losses. The empirical statistical method is one of the methods that can be used to predict landslides by taking input data from the history of previous landslide events. This research aims to find the best modeling form for sliding distance prediction and which parameters influence a landslide's sliding distance prediction. This study used multiple linear regression methods. The data used in this study are geometric slope parameters in the form of slope height (H), original slope (θ), landslide area (A), and rock type (RT). The data was taken from the 2015-2021 PVMBG landslide investigation report and used the Google Earth and Global Mapper program. Based on the analysis of the best empirical model that can predict the sliding distance of a landslide log Lmax = 0,387 – 0,097 RT + 0,230 log H + 0,458 log A – 0,220 tan θ with an R2 value of 0,94 and an average estimated error of 31,56%. The parameter that has the most influence on the prediction of sliding distance is the area affected by the landslide (A).

The success of the construction sector is inseparable from cost and quality, it is reported that identified quality failures reach 5-20% of the project contract value. To reduce quality failures and failure costs in the implementation of construction projects, it is necessary to provide cost of quality (COQ) assistance. In this research, reinforced concrete construction was chosen as the object of COQ assistance because it is a critical part of the structure. The purpose of this research is to categorize the COQ from internal and external factors and analyze the potential costs incurred for these failure factors. Analysis of the cost of quality failure was carried out based on the weighting of the results of the pairwise comparison matrix to obtain consistency index (CI) and Consistency ratio (CR) values and using the Kruskal Wallis test as a non-parametric test approach. The results of this research indicate that COQ greatly influences profitability, where the failure of the highest internal quality is the work method factor which affects the failure of the final concrete result in the form of structural and visual defects, while the highest external quality failure is the product selection factor at the client's request which causes the resulting construction products are not in accordance with the specifications or not in accordance with the expected function. Based on the causal factors of the quality failure, the implementation control process affects the result of product quality to the point of causing clients to demand, replace, and repair during the warranty period. Failure costs that affect the highest contract value amounted to 7.26% of internal failures and 6.40% of external failures.

Road construction projects in Indonesia are often located on volcanic soils, where borrow pit options will be limited to volcanic soils. In the construction of compacted earth roads generally have an immediate settlement, but in fact there is a long-term settlement in compacted soil. In general, the compaction carried out in the field is different from that in the laboratory. Where compaction in the field leads to static conditions while in the laboratory it is dynamic. This study aims to analyze the mechanism of static or dynamic compaction and its relationship with compressibility. Determination of creep using Oedometer testing with saturation and unsaturated methods. Laboratory test results show that different compaction methods will affect the dry unit weight value of the soil, where in this test the dry unit weight value for dynamic compaction is 1,38 g/cm3 and for static compaction it is 1,44 g/cm3 or an increase of 4,35% to 7,96% . The value of the secondary consolidation coefficient increases along with increasing load on the Oedometer test, but with different characteristics for each sample. In this study, the secondary consolidation coefficient tends to decrease by 10% – 40% when using higher compaction energy. While the compressibility index value decreased to 52%.

The confluence of the three largest plates in the world between the Indo-Australian, Eurasian, and Pacific plates makes Indonesia a potential area for landslides. A landslide is the movement of a mass of soil or geology through a sliding plane down a slope. Bengkulu Tengah Regency, which is in Bengkulu Province, is an area prone to landslides, this can be seen based on previous events, which have caused people to experience loss of property and loss of life. Distribution Analysis of landslides is a method used to identify areas with potential levels of landslides starting from low to very high, which allows people to be more vigilant. The purpose of this study is to determine the distribution of landslide susceptibility and dominant factors that influence the level of landslide potential. The research method was carried out by giving weights and scoring with reference to Puslittanak. The making of landslide map was obtained from the results of overlaying secondary data such as DEM, distribution of land cover, distribution of rainfall, geological distribution, and distribution of soil types using the ArcGIS 10.7 application. The results showed that the level of landslides distribution in Bengkulu Tengah Regency was dominated by the distribution level of moderate landslides covering an area of 73455 Ha with a percentage of 60%. Areas that have a very high distribution of landslides are in four sub-districts consisting of Taba Penanjung, Meringgi Kelindang, Meringgi Sakti, and Pematang Tiga sub-districts with an area of 8948 Ha with a percentage of 7%. The rainfall map distribution had the highest value, which the most dominant factor in the process of landslide occurrence.

Heaps of waste that are in the TPA must be covered with soil on a regular basis in accordance with the TPA management regulations. The provision of material (soil) as a material for covering Landfills requires a lot of money, so that the closing activities of Landfill waste often experience problems. In this research, a study was conducted on soil substitute material as a cover layer for waste piles in the form of FABA. Part of the soil material commonly used as layering is substituted with FABA mixed with lime, the lime serves to bind the soil and FABA. The composition of the mixture is FABA 75% + 5% lime + 20% soil, FABA 75% + 10% lime + 15% soil, and FABA 90% + 5% lime + 5% soil. The purpose of this study was to determine whether FABA could be used as a substitute material for layering in the development of Landfill layering technology. The mixed material was tested for strength characteristics in the laboratory in the form of permeability tests, soil unit weight, shear strength, sieving analysis, Atterberg Limit, and CBR and compaction. This material strength parameter is then used in layering modeling with the help of geotechnical software. The results showed that the FABA material mixture did not meet the requirements as a waste layering material with a permeability value that did not meet the requirements in the sanitary Landfill system, although had a good carrying capacity value based on the cohesion value and soil shear angle as well as the Landfill stability value.

The development times have been accompanied by an extremely quick development, which brought architectural features like geometric imperfections and soft store buildings. Buildings having high earthquake risk in Sorong have challenges due to an active fault.. This study's goal was to identify the relationship between displacement and drift ratio and structural performance in high-rise structures with and without set backs. Using structural analysis software, the building was modeled in this study with a maximum of 7 stories and a total height of 37 m. Seismic forces were also analyzed using reflection spectroscopy of various responses. Buildings with soft storey effects without set backs and buildings with soft storey effects with set backs are the two types under study. According to the research, soft store buildings with set backs produce the highest displacement and drift ratio outcomes when compared to soft store buildings without set backs. Based on the service limits' performance under earthquake loads, it is still within safe bounds.

Dam is a building across a river built with the aim of creating a reservoir. Due to the large volume of water, the dam has a very large potential for danger if failure occurs. Dams need to be managed properly, one of which is through regular inspections. The results of the inspection can be used to analyze dam risks. The Haekrit Dam was originally a reservoir whose classification was upgraded to dam due to the enactment of Minister of Public Works Regulation No. 27 of 2015 concerning Dams. The Haekrit Dam needs to be analyzed for its risks as a dam. The method for analyzing the risk of dams can use the modified Andersen method. This method works well for dams with limited information during construction and instrumentation. This research requires a report on the results of field inspections to determine the physical condition of the dam. The end result of this analysis is the dam risk condition in the form of a safety value (Naman). The safety value obtained is 78,1. Based on the risk assessment of the modified Andersen method, the Haekrit Dam has a safety value above 75 (satisfactory), which means that the dam is in good condition and has a low risk of failure. A satisfactory safety value means that the dam can operate properly at ordinary (normal) and extraordinary load times.

Post-earthquake development in Indonesia is a complex challenge that requires cross-sectoral efforts and support from various parties. Indonesia is prone to earthquakes due to its location on the Pacific Ring of Fire, an active area of earthquakes and volcanic activity. The use of precast concrete has a number of important advantages in earthquake-prone areas but the connection between joints can be a weak point if not done properly. This study will discuss the connection system, connection location, and details. The research method used is numerical analysis using finite element-based software. It is concluded that the connection system used has not been able to reach the capacity of the monolith beam without connection, while the addition of bamboo does not have a significant effect on the bending capacity of the beam.
