Concrete is an important component in the manufacture of infrastructure, but in its various advantages, concrete also has deficiencies in the elements of its manufacturing materials, concrete which can cause environmental damage. Not only that, another problem was also found, namely the amount of asbestos waste being wasted. In addition to being difficult to decipher in nature, asbestos also has an impact on human health, namely lung cancer. From there, researchers are interested in conducting research and finding solutions. The purpose of this research is to find out the results of testing the compressive strength of K-250 concrete with the use of asbestos powder waste and to review the use of asbestos powder waste as fine aggregate efficiency.This study uses an experimental method with data analysis to find the results of testing the compressive strength of K-250 concrete. The test will be carried out on 12 specimens with asbestos waste variance of 0%, 10%, 20%, and 30% as a substitute for fine aggregate. From the test results obtained data on the compressive strength of concrete at the age of 28 days, namely: 0% = 217.8 Kg/cm3, 10% = 238.1 Kg/cm3, 20% = 188.7 Kg/cm3, and 30% = 100 ,1 Kg/cm3, which concludes that K-250 concrete with a variance of 10% meets the compressive strength.

Roads with soft subgrade have low bearing capacity. The result is non-uniform soil settlement. One way to overcome this is with soil stabilization. Stabilization of clay soil is done chemically with palm bunch ash and cement. The purpose of this study was to determine the bearing capacity of soil for the shear strength value of clay soil with variations in mixing 5%, 10%, 15%, 20% oil palm bunch ash, and 10% cement with a 7-day curing period, and then the samples were tested using a direct shear test tool SNI 3420: 2016. The results showed that in the addition of a mixture of oil palm bunch ash and cement with levels of 5%, 10%, 15%, 20%, and 10% cement, the cohesion value increased at a percentage of 20% oil palm bunch ash and 10% cement, namely 0.5448 kg/cm2 compared to the cohesion value in the original soil of 0.0081 kg/cm2, an increase of 98.51%, and a shear angle value of 53.12° while the value of the original soil shear angle was 16.93°. This research concludes that the shear strength value of clay soil stabilized with oil palm bunch ash and cement increases.

Sometimes the execution of a project does not proceed smoothly because there are barriers that impede the present work. Uncertain weather conditions are one of the most common challenges encountered in the field during the Tanjung Perak Diamond Pier Structure Strengthening project in Surabaya. This is because the initial planning did not account for the weather conditions that would occur during the project's implementation. As a result, rescheduling is carried out to generate a reasonable and realistic timetable. Many strategies are employed in scheduling, with the expectation that the method will help in planning and scheduling. The goal of this research is to determine the time necessary for project implementation after rescheduling. This research is analytical in character. Secondary data, such as schedules and Budget Plans (RAB), are collected by directly requesting the necessary data from related parties, then evaluating the initial schedule, and finally preparing a new schedule using Microsoft Project tools and the Critical Path Method (CPM). The results of this study obtained a rescheduling duration of 99 days, 22 days faster than the actual planned duration of 121 days, and a fee of IDR. 28,535,441,605 of the initial planned cost of IDR. 35,017,986,296.10.

In this project using a pile foundation, but during the foundation work there were several obstacles, namely hydraulic tools that were still not ready to use, hydraulic tool repairs, and piles that were one week late, causing delays in foundation work.Therefore workers cannot work optimally while waiting for the tools to arrive. In addition to delays, there are also cost overruns where workers are still being paid for work that is not optimal, so it is necessary to compare these foundations with other foundations in order to find differences in foundations that are more efficient and minimize the problems that have occurred. From the results of data processing, it can be seen that the duration of time required for the preparatory work to the 30x30cm pile foundation with a depth of 16m for 65 points on the class 2 marine and beach guard base of Tanjung Perak is 56 days and requires a fee of IDR 655,305,366.00. For the duration of the preparatory work up to the 30cm bore pile foundation with a depth of 16m as many as 65 points on the class 2 marine and beach guard base Tanjung Perak is 59 days and requires a fee of IDR 520,779,603.00. Then the difference in time between the pile foundation and the bore pile foundation is 12 days. The pile foundation can save as much as 21.4% or 12 days of time from the bore pile foundation.

This study aims to analyze the application of Precast half-slab formwork with conventional formwork in terms of cost and time. The use of precast concrete is based on advantages in terms of economy, efficiency, speed in implementation, and energy consumption which has an impact on the environment. This office construction project was carried out in the Graha Family area in Surabaya. This project uses the half slab precast method, where half of the plate (precast) is precast with a thickness of 7 cm, and the other half is cast on site (topping). In this final project research, an analysis and comparison of several methods of floor slab work is carried out so that it can be seen which method is considered more profitable. Analysis of conventional half slab and precast methods focuses on calculating direct costs in terms of materials, tools, and workers' wages as well as calculating the time needed to complete the work.

The ARIMA method is a non-stationary homogeneous time series model that uses the procedure for applying the Autoregressive model or scheme and the Moving Average in preparing its forecasts. The purpose of this study was to determine the application of the Autoregressive Integrated Moving Average (ARIMA) method and minitab application at PT. Bumi Sarana Beton in planning the estimated number of work orders. It can be concluded that for K-225 the best model is the ARIMA model (2,0,0) because it has the lowest MSE value and for K-400 the best model to use is the ARIMA model (2,0,2 ) because it has the smallest value. From the results of the research that has been done, it can be concluded that the production of K-225 in 2022 is 3573.50 m3, while using the ARIMA method in 2023 the total production is 3920.61 m3 and in 2024 the total production is 3573.50 m3. to 3824.36 m3. Production of K-400 in 2022 was 2015.00 m3, while using the ARIMA method in 2023 a total production of 1857.07 m3 was obtained and in 2024 a total production of 2045.89 m3 was obtained.
