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.

Construction project resources are one of the essential things in a construction phase. Every year, contractor performance decreases due to limitations in managing and managing project resources. One way contractors can deal with these problems is to improve quality performance during construction. One of the causes of problems at work is the resource factor. The resource factor in the construction process dramatically influences the contractor's performance. This study aims to analyze how much influence each factor of project resources (human resources, materials, equipment, implementation methods and information technology) of the project has Connecting Bridge, Patimban Port Development Project. The study collected sample data on 33 people involved in the project development process analysis using SEM-PLS analysis with the help of SmartPLS 3.0. From testing, this study's results indicate a positive and significant influence between the variables of human resources, materials, equipment amd implementation methods. This study's results obtained from the R square for the contractor performance variable were 0.809. It means that the percentage of human, material, equipment, implementation methods and information technology resources is 80.9%, while other factors influence the remaining 19.1%.

The use of fly ash or fly ash is still minimally applied in Indonesia. The percentage of fly ash utilization is only 10-12% with 73% on Java Island and 27% on other islands, so there will be an accumulation of fly ash of up to 10.4 million tons per year by 2027. Abundant fly ash can be utilized by making lightweight brick the main composition as a substitute for cement called geopolymer lightweight brick. The fly ash used is class F with mechanical testing based on the Si/Al ratio. This research was conducted to analyze the effect of activator content on mechanical testing consisting of compressive strength, split tensile strength, and modulus of rupture in order to obtain the mechanical properties of lightweight geopolymer bricks. The higher of the activator content, got the greater Si/Al ratio. The ratios at activator levels of 35, 40, and 45% were 2.42; 2.45; and 2.48. The difference between split tensile strength and compressive strength for 35% activator content is 6.45%; 40% is 5.94%; and 45% is 6.04% so it is included in high quality lightweight brick. The level of activator has a significant effect on the compressive strength, split tensile strength, and modulus of rupture. The lower Si/Al ratio results in higher and better compressive strength, split tensile strength, and modulus of rupture.

A landslide occurred in Sumbernanas village, Gedangan district, Malang regency. This incident caused the 50 m of the road along the Gedangan – Gondanglegi section to collapse as much as 3 m deep. Some repairs were attempted, however it did not bring expected results. This study aims to analyze the causes of the road collapse and develop effective methods of measurement. The research comprise; field observations, study of regional geological conditions, in-situ soil investigations, topographic measurements, data processing and analysis. Design parameters were determined through back-calculation analysis of the stability of the slopes at the time of the collapse. The results indicated that the collapse was caused by the combination of scouring of the river channel banks and soil softening as a result of groundwater infiltration. The proposed measurement method is installation of a gabion construction to function as a retaining wall. Based on structure calculations obtained, the safety factors are (SF)> 1,5 for the short term and SF> 1,1 for the long term.

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 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.

The government prioritizes enhancing the Water Supply System (SPAM) to meet public needs, targeting clean water services 98.49% coverage in Tangerang Regency by 2031. To achieve this target, the strategy of Perusahaan Umum Daerah Air Minum Tangerang Regency (PERUMDAM TKR) involves expanding transmission and distribution networks, potentially causing adverse environmental impacts. This study identifies variables influencing cost optimization through Green Infrastructure implementation in SPAM, focusing on the leading distribution pipeline network. A quantitative method using SEM-PLS analyzes questionnaire data from experts. Results indicate that green design affect cost performance with system energy design maturity being a significant indicator. A case study in Tangerang Regency employs Value Engineering (Sudiarsa, 2018) and Life Cycle Cost Analysis for investment cost optimization through Green Infrastructure. VE leads to a 9.91% cost increase, exceeding the 7% efficiency standard. LCCA shows project feasibility with NPV > 0 (Rp77,321,059,290.18), IRR of 27.73% (exceeding the 6.95% discount factor), and a 3.05-year payback period. Sensitivity analysis reveals that a 10% rise in total cost and a 40% fall in total revenue render the project unfeasible (NPV < 0).
