Abstract

Testing the concrete structure after the concrete has hardened is to determine whether the concrete structure is suitable for use according to the planned quality. Concrete quality testing is carried out without damaging the concrete. This study aims to find out how to identify the quality of spun pile, to know the differences in methods and results between the core drilling test, compressive strength test, and concrete hammer test, and to find out which method is more effective for identifying the compressive strength quality of spun pile. The method used to determine the capacity and structural strength of spun pile using 3 test methods, namely the Core Drill Test, Schmidt Hammer Test, and Compressive Strength Test methods are used as an alternative in determining the compressive strength value of spun pile. The results of the concrete compressive strength test on spun pile using the Core Drill Test, Schmidt Hammer Test, and Compressive Strength Test methods have fulfilled the requirements. The results of the compressive strength test using the core drill test method obtained an average yield of 50.98 Mpa for spun pile fc 45 and 55.83 Mpa for spun pile fc 50. From the results of the Schmidt hammer test it indicates that the coefficient of variation (KV) of the overall spun pile samples tested ranged from 3.19% -4.72%. The Compressive Strength Test obtained an average compressive strength of spun pile fc 45 of 57.22 MPa for a 28 day old concrete sample. As for the spun pile fc 50, it obtained an average yield of 64.35 MPa for a concrete sample aged 28 days. Based on data analysis, the effectiveness of testing the compressive strength of concrete can be concluded that the Core Drill Test is very effective in testing the compressive strength of concrete.

Abstract

ABSTRACT The development of construction projects generally contains activities that are very risky and have the potential for unwanted events to occur. The risks that may occur on the project vary greatly due to the factors of the workers themselves and from the project environment, from these risks it is possible that construction work is one of the supporters of a fairly high number of work accidents. Therefore, a way or effort is needed by identifying a risk in work accidents that may occur from each job on the Siti Khodijah Sidoarjo Hospital Building construction project to minimize the number of work accidents on the project. This research uses descriptive qualitative methods that aim to explain a problem formulation and describe solutions in depth and detail. Descriptive qualitative method is by conducting direct observations in the project environment, interviews with safety officers or K3, and literature studies to identify risks that may occur in the Siti Khodijah Sidoarjo Hospital Building Construction Project. The results of this study obtained 34 risks of work accidents which were reviewed from four variables, namely materials, tools, workers or humans, and the environment. The risks of work accidents were obtained from interviews, observations, and literature studies. The results of the 34 risks of work accidents based on the variables found there are 11 risks from the material variable, 9 risks from the tool variable, 9 risks from the worker or human variable, and 5 risks from the environmental variable.

Abstract

The quality of concrete is declared high if it is able to withstand the force load exerted during high compressive strength tests, one of which is the quality of fine aggregates to be used in making concrete. This study aims to determine the influence of the substances contained or the level of sludge present on fine aggregates. The research method was carried out by taking laboratory testing data on sludge content by testing slump and compressive strength of concrete samples aged 28 days cylindrical with a diameter of 10 cm and a height of 20 cm with 5 variations of fine aggregate sludge content of 1.5%, 1.7%, 2.4%, 2.7%, 3.6% with a planned f'c of 50 Mpa. The results of slump test testing studies on variations in sludge content of 1.5%, 1.7%, 2.4%, 2.7%, and 3.6% have different slump values, the higher the sludge content, the higher the slump value or the thinner the concrete mixture. The mud content of 1.5% has a slump value of 5.5 cm while the mud content of 3.6% has a slump value of 7.5 cm. The compressive strength results on the test specimen at the age of 28 days, the higher the mud content, the decrease in compressive strength and quality values. At 1.5% mud content produced an average compressive strength of 494.3 kN and an average concrete quality of 62.972 Mpa, while at 3.6% mud content produced an average compressive strength of 414 kN and an average concrete quality of 52.738 Mpa.

Abstract

Indonesia has many high-rise buildings for residential, office, and others. Indonesia is a country that has experienced many natural disasters such as earthquakes which have an impact on the structural strength of buildings, especially high-rise buildings. This research was conducted to determine the variations in the dimensions of the structural column sizes in a building that affect the strength of the building structure when reacting to an earthquake assisted by using the SAP2000 V14 software. The method used in this study is by using modeling analysis using SAP2000 software. The results of the research on changes in column dimensions on the strength of tall building structures affect displacement that occurs due to earthquakes, where the variation of column dimensions is 6 times, the smaller the displacement value of the building and the more axial force values ??that the building structure can accept so that the building becomes better. conversely, in the variation of the column dimensions with 4 changes, the value obtained at the displacement is greater and the value of the axial force that can be accepted by the structure is smaller so that the strength of the structure in the building is getting worse.

Abstract

Changes in the function of the Magna One Surabaya Building, originally Full Office to Mixed Use to meet the market share needs for vertical housing in the West Surabaya area. This resulted in a change in the dimensions and quality of the concrete in the column structure of the building. This research was conducted to compare the column structure deviation of the two building models due to changes in building function. The research method uses SAP 2000 software and refers to SNI 1726:2019. Results in this study, it was found that the mass of the Mixed Use structure is greater than the Full Office structure with a percentage value increase of 0.3% in structural mass due to the addition of column reinforcement in the form of extra main reinforcement, extra stirrup reinforcement, and the addition of hooks to the 16th to 19th floor structural columns. Axial force the Mixed Use structure is 17484.71 kN, the maximum deviation value is 41.2 mm in the safe category not exceeding the permit delta, the Base Shear Reaction value is greater in the Mixed Use structure, for the Mixed Use period it is 4.24 seconds which is 6.19% more smaller than the period of the Full Office structure. The structure period that works on the SAP 2000 program is still within safe limits of no more than 5.425 seconds so that the Mixed Use structure is more effective.

Abstract

The slope is an inclined plane area that connects other planes that have different elevations. Each slope has the possibility of landslides. According to SNI 8470-2017 regulations landslides can occur if the safety factor does not meet the Safety Factor (SF <1.5). The slopes in one of the Jombang districts, to be precise in one Ngrimbi Village, Bareng District, tend to have poor soil and landslides can occur, so a slope stability analysis is needed. In this study, the authors conducted an evaluation and review of slope stability in residential areas under the slopes of Ngrimbi Village, Bareng District, Jombang Regency to determine the slope safety factor (SF) value using the Geoslope 2023 software program. Soil data used in this study used the Geoslope 2023 software program. parameters liquid limit value (LL) = 35%, 45%, and 50% obtained from soil data from previous research literature studies. The data is connected or correlated to obtain values of the soil shear angle (?) and soil cohesion (c). The results of this study obtained slope stability at Liquid Limit (LL) 35% (SF) = 1.224 < 1.5 (Unsafe), Liquid Limit (LL) 45% (SF) = 1.043 < 1.5 (Unsafe) and Liquid Limit (LL) 50% (SF) = 0.976 < 1.5 (Not safe).
