The frequency of tidal floods caused by seawater threatens coastal buildings. This study aims to see how using seawater for concrete treatment affects the resulting compressive strength. This study used additives such as Bestmittel to expedite hardening and boost compressive strength, as well as silica fume to increase porosity and prevent concrete from becoming porous owing to chloride ion intrusion from seawater. The findings of concrete compressive strength tests were achieved through laboratory testing using cylindrical test objects measuring 150 mm in diameter and 300 mm in height. The test specimens were ordinary concrete with 0.6% bestmittel and a Silica Fume combination with varying percentages of 15%, 20%, and 25% substituting partial cement. Meanwhile, the concrete treatment employs both fresh water and seawater. Pressure tests were performed at 14 and 28 days. At 14 days, concrete with fresh water treatment and a bestmittel content of 0.6% and silica fume concentrations of 15%, 20%, and 25% have compressive strengths of 25.53 MPa, 27.11 MPa, and 26.04 MPa, respectively. Meanwhile, it was 26.34 MPa, 27.61 MPa, and 26.75 MPa after 28 days of concrete age. At 14 consecutive days of concrete age, concrete with seawater treatment had a reduced compressive strength. 19.66 MPa, 22.13 MPa, and 23.07 MPa, respectively. Meanwhile, at 28 days, the pressures were 20.53 MPa, 24.77 MPa, and 25.53 MPa. Using 6% bestmittel followed by 15-20% SF can boost the strength of the concrete and let it survive reduced compressive strength due to seawater infiltration.

The success of a construction project performance can be seen from the timeliness of completion of the implementation of work that has been agreed upon by the owner and contractor. Efforts that can be made to maximize project performance include including overhead costs in the project cost budget plan. Overhead costs are included in indirect costs along with unexpected costs, profits, taxes and others. The fact that occurs in the field in the implementation of the construction of flats within the Ministry of Public Works and Public Housing, implementing contractors who provide offers with indirect costs of ≤ 10% on average there is a change in the time of completion of the implementation of work, while there are some executing contractors who do not offer indirect costs but can complete the work on time. On the basis of the foregoing, it is necessary to conduct research on whether indirect costs affect the performance of the time of implementation of construction projects. Data collection was carried out by distributing questionnaires to respondents involved in the construction of flats within the Ministry of Public Works and Public Housing, namely service users or owners and construction service consultants. Data processing is carried out by statistical analysis methods with the help of SPSS software version 24.

Building Construction is a compulsory subject in the Building Engineering Education Study Program which is expected in this course to have the ability to design systems and infrastructure in the civil engineering field as needed by considering various constraints such as economic, environmental, health, and security constraints. Covid-19 harms life so the world of education also wants to participate in breaking the spread of the Covid-19 virus. The subsidized houses that have been built have met the existing requirements, although they are not perfect, they can still be said to be livable houses. However, a serious problem is that after being given a lot of people added the initial building but did not meet the requirements. This development research produces project-based teaching materials products. This study uses the development of Borg and Gall with the stages of analyzing potential problems, data collection, product design, design validation, design revision, product testing, revision, and reporting. The teaching materials developed contain the characteristics and designs of disaster response houses adapted to the Building Construction course material and are project in nature. The results of the study obtained that the teaching materials developed were suitable for use as teaching materials in the process of learning activities based on the overall average score of the material expert aspect of 3.6 and the media expert 3.6 very good category.

This study examines the factors that influence the application of the activity-based costing (ABC) method in construction projects. This research adopts a quantitative approach by developing a case study model. The study tested the model on a sample of 24 hydromechanical and gate works, weirs, irrigation networks, river protection, dams and ponds, coastal protection, swamp infrastructure, groundwater infrastructure, and raw water infrastructure. Primary data collected from field surveys. This study found that the proportion of indirect costs, competitive pressures in price and quality, and product diversification significantly influence a company's decision to apply the ABC method. There were found to be implications for managerial practice and public policy. It is hoped that this research will be useful in meeting the planning needs that are currently being addressed.

In 2021 it is estimated that there are 19,836 people at Universitas Jambi Kampus Pinang Masak Mendalo. One of the most important aspects to support activities in Universitas Jambi Kampus Pinang Masak Mendalo is a clean water supply. This study aims to determine clean water needs, to analyse hydraulic factors such as water discharge, flow speed, water pressure, and head loss using EPANET program, and to calculate the budget required to build a water distribution pipeline system. The results of water distribution pipeline network design are clean water needs at Universitas Jambi Kampus Pinang Masak Mendalo as much as 665,910 liters/day or 18.4975 liters/second and at the maximum daily needs as much as 732,500 liters/day or 20.3472 liters/second in the projected year of 2031. Analyses of hydraulic factors in the pipeline distribution system using EPANET program and manual calculation give the same results, but there are some pipe segments that do not fulfill of flow velocity standard, that are on pipe A1 = 0.15 m/s, B1 = 0.08 m/s dan pipa B2 = 0.25 m/s. The cost required to build a clean water distribution pipeline network at the Universitas Jambi Kampus Pinang Masak Mendalo, is amounting Rp238,252,263.00,-
