Abstract

Construction Management can be in the form of a business entity in which human resources are needed who are experts in their respective fields which include POAC (Planning/Planning, Organizing/Organizing, Actuating/Implementing, and Controlling/Supervision). The Garut District Health Office Development Project was built to improve the quality of the office and improve the quality of public services. In the implementation of a project, of course it cannot be avoided from various problems that slowly arise. This is a serious challenge, how will the construction management itself try to solve various problems that occur so that it can proceed according to the initial plan. This study aims to find out what factors influence the performance of construction management in and to find out the actions taken to overcome the problems that occur so that the implementation of construction management can run well. The method used in this research is ranking analysis method. This study involved consultants and contractors to fill out a questionnaire. There are 30 respondents in this study. The results of this study are that the factors that influence the construction management work system are mostly in the supervision or controlling process, which obtains an average value of 3.56. To control the factors that affect the construction management work system in the control process, you can analyze the constraints that occur in the field and then catch up on delays in progress that occur quickly and precisely.

Abstract

Candlenut shells are hard and light, so there is potential to obtain a lighter weight concrete structure but of greater quality by partially replacing it or adding coarse aggregate with candlenut shells. In this research, candlenut shells were used as a substitute for coarse aggregate in the concrete mixture. The aim of this research is to determine the mechanical properties (compressive strength, split tensile strength and deflection strength) of concrete with the addition of candlenut shells and superplasticizer. The method used in this research is a quantitative method. The amount of candlenut shell material used is a substitution for the volume of coarse aggregate of 15%, 30% and 45%. There were two types of samples made in this research, including cylindrical samples with a diameter of 15 cm, height 30 cm, and blocks with dimensions of 10 cm x 15 cm x 60 cm. These samples were made for testing the compressive strength of concrete, splitting tensile strength of concrete and deflection strength of concrete. Concrete with the substitute material for candlenut shells is expected to achieve the planned compressive strength target of 20 MPa. Based on the test results for compressive strength, split tensile strength and concrete deflection strength, the average value for each variation was obtained. Mixture 1 (0%) has an average compressive strength value of 25.68 MPa, an average split tensile strength of 2.11 MPa, deflection strength of 2.85 MPa. Mixture 2 (15%) has a compressive strength of 20.28 MPa, split tensile strength of 1.55 MPa, deflection strength of 1.49 MPa. Mixture 3 (30%) has a compressive strength value of 16.64 MPa, split tensile strength 1.41 MPa, deflection strength 1.24 MPa and for Mixture 4 (45%) the compressive strength value is 12.96 MPa, split tensile strength 1.25 MPa, deflection strength 1.00 MPa.

Abstract

Roads are important in the distribution of goods in the industrial sector. Good roads can speed up the distribution process from one area to another. On the other hand, if the road conditions are bad, it will certainly slow down distribution in the area. Therefore, road damage conditions can affect the economic sector in the area. There are many factors that cause damaged road conditions, one of which is the volume or load of vehicles that exceeds the capacity of the road. The impact of road damage will certainly disrupt the comfort and safety of road users. This research was carried out using a survey method, directly observing the condition of road damage and distributing questionnaires to road users. Then the test is processed with Validity Test, Reliability Test, Mean Value and Standard Deviation. Based on the findings, the types of damage were Crocodile Skin Cracks, Longitudinal Cracks, Potholes and Bleeding. Then, based on the distribution of the questionnaire, all statement items are declared valid and reliable. Then, based on the mean value, it is obtained that the accident factor is the aspect that most influences the safety of road users. The road flooding factor is the aspect that has the most influence on comfort. Then the delay factor is an aspect that influences costs.

Abstract

Parking areas are one of the transportation infrastructures that must be well organized and managed in order to meet the need for adequate and appropriate parking spaces. The problem that occurs at Kerkof Culinary Tourism on weekends is that the parking requirements for two-wheeled vehicles exceed capacity, resulting in four-wheeled vehicles being parked on the road and causing traffic jams. This research aims to evaluate the capacity of motorized vehicle parking in the Kerkof Culinary Tourism area. The method used was a direct survey of the number and duration of parked vehicles at the research location as well as an analysis of parking needs. The analysis results show that the parking capacity for two-wheeled vehicles covering an area of ​​486 m2 for current conditions is 324 SRP with a parking index of more than 100%. This indicates that the parking area in the Kerkof Culinary Tourism area is no longer able to accommodate the demand for parking for two-wheeled vehicles. So an evaluation was carried out with the results of the need for two-wheeled vehicle parking area of ​​958.5 m2 with 639 SRP.

Abstract

Indonesia is intensively developing various infrastructure such as buildings, mosques, roads, bridges, dams and much more. Detailed planning is needed so that construction runs smoothly and results are maximum, including planning the budget (RAB). One method that can help identify significant costs in construction projects is the Cost Significant Model Method. The Cost Significant Model method is a cost analysis method that can be used to identify significant costs in construction projects. This method uses multiple linear regression analysis. In Indonesia, building district roads is a priority to improve connectivity and community welfare. Applying the Cost Significant Model in the Garut district road project is very important for efficient cost management. The aim of this research is to identify significant cost factors in district road projects and analyze the effect of implementing the Cost Significant Model on project cost management in the region. The research results show that the cost significant model provides accurate cost predictions with a coefficient of determination of 0.943, indicating a significant influence of variables on project costs. The variables Asphalt pavement division (X4) and structure division (X5) have a significant influence on project costs, so they can be prioritized to manage risks and reduce the impact of unexpected costs. The conceptual cost estimation model from this research is Y = -339907740.45 + 380172.81 (X4) + 117874.24 (X5). Testing the validity of this model shows that the cost estimation using this model is more accurate than using the average price per square meter times the building area. The Cost Significant Model method is an effective tool for managing road project costs in Garut Regency. This can help project managers predict costs more accurately and identify factors causing cost increases.

Abstract

Tannery sludge waste is solid waste produced by the leather tanning industry. This waste is B3 waste because it can cause itching on the skin, health problems and give off an unpleasant odor. However, this waste also contains the same compounds as cement, namely iron and aluminum, so it can be used as a substitute material for clay soil with the aim of increasing the soil's bearing capacity. Clay soil is considered poor soil if it is to be used as the basis for construction. Therefore, research was carried out on the physical properties of clay soil mixed with tannery mud waste. The method used is experimental, where the physical properties of clay soil are tested, consisting of water content, bulk density, specific gravity, sieve analysis, and Atterberg limit, plus a mixture of tannery mud waste in proportions of 0%, 25%, 50%, and 75%. % of soil weight. The results of the research showed that clay soil with the addition of tannery sludge waste resulted in a decrease in water content; increase in unit weight and specific gravity; the proportion of fine grains decreases and coarse grains increase; as well as an increase in the plasticity index.

Abstract

Pasir Bajing TPA is the only TPA with a Sanitary Landfill system in Garut Regency. The increasing burden of landfills along with population growth makes the feasibility of the Pasir Bajing landfill interesting to study. This research aims to analyze the technical feasibility of the Pasir Bajing TPA and evaluate the feasibility of waste storage buildings in the Sanitary Landfill system at the Pasir Bajing TPA. The research method used is descriptive evaluative. Data obtained directly through field surveys. The technical feasibility of the landfill was analyzed based on SNI-03-3241-1994, while the feasibility of the waste storage building was analyzed using SNI 03-6154-1999. The research results show that the Pasir Bajing TPA technically does not fully meet the requirements according to SNI-03-3241-1994 because there are no monitoring wells, leachate collection buildings, drainage is not yet effective and a new weigh bridge has been built. The evaluation results of the waste storage building show that in terms of dimensions it meets the criteria of SNI 03-6154-1999. Based on the calculation of the capacity of the waste holding building, it is able to accommodate waste for the next 2 years, however, in terms of strength, it is not suitable because the height of the embankment and the height of the embankment or gabions do not match the strength to hold the embankment in the event of a shock or landslide.

Abstract

To withstand earthquake forces in earthquake-prone areas, especially in seismic design categories 4,5,6 according to SNI 1726:2019, there is a calculation called the Special Moment Resisting Framing System (SRPMK). This research aims to understand the concept of earthquake-resistant buildings, plan reinforced concrete structures according to SRPMK principles, and determine the fulfillment of the Strong Column Weak Beam rule where columns are designed to be stronger than beams. The case study was carried out at the Garut Regency KORPRI building using the Garut Regency spectrum response. This building functions as the secretariat for the district KORPRI management board, as well as providing general administration services. The analysis is carried out by knowing the response spectrum, modeling, entering loads, and load combinations. The results of this research show that to fulfill the Special Moment Resisting Frame System in the KORPRI Garut Regency building, beams with dimensions of 350 x 500 mm and column dimensions of 400 x 400 mm are required and reinforcement is installed by the SRPMK provisions contained in SNI 2847:2019. This calculation also includes compliance with the Strong Column Weak Beam rule, this is related to the calculation of compliance with the SCWB formula in SNI 2847:2019
