Abstract

The current development in the construction industry is rapidly advancing. Regardless of any construction process, it takes a considerable amount of time to complete from start to finish. Therefore, careful considerations are needed to determine the most appropriate and efficient way to execute a construction project. Tanjung Perak Class II Sea and Coastal Guard Base (Pangkalan Penjaga Laut dan Pantai or PLP) is a Technical Implementation Unit under the authority and responsibility of the Directorate General of Sea Transportation, as regulated by the Ministry of Maritime Affairs. In this project, pile foundation is being used. However, during the foundation work, several challenges arise. These include the unavailability of ready-to-use hydraulic equipment, hydraulic equipment repairs, and a one-week delay in the arrival of the pile foundation, which leads to a delay in the foundation work. As a result, the workers cannot maximize their productivity while waiting for the equipment to arrive. In addition to the delay, there is also a cost escalation, as the workers are still being paid despite not being able to work at their maximum capacity. Therefore, a comparison between the current pile foundation and alternative foundation types is necessary to find a more efficient solution and minimize the encountered challenges. Based on the data analysis, the duration required for the preparation work and the installation of 65 points of 30x30cm pile foundation with a depth of 16m at Tanjung Perak Class II Sea and Coastal Guard Base is 8 weeks or 56 days, with a cost of Rp 670,742,965.00. On the other hand, the duration for the preparation work and the installation of 65 points of 30cm bore pile foundation with a depth of 16m is 69 days or 10 weeks, with a cost of Rp 520,779,603.00. From the discussions and deliberations above, the time difference between pile foundation and bore pile foundation is 13 days. Bore pile foundation takes 13 days longer than pile foundation. The cost difference between pile foundation and bore pile foundation is Rp 149,963,362

Abstract

Human resources play an important role for the success of an organization or company system. Because humans are living assets that need special attention by companies. The fact that humans are the main asset in an organization or company, must receive serious attention and be managed as well as possible. This is intended so that the human resources owned by the company are able to provide optimal contributions in efforts to achieve organizational goals. It is in the management of human resources that management is required to be able to manage resources in a systematic, planned and efficient manner. In human resource management, there is also one thing that must be a concern, namely, the occupational safety and health system. Occupational safety and health (K3) issues in general in Indonesia are often neglected. This is indicated by the still high number of work accidents. In Indonesia, especially in the business world that requires a large workforce such as construction projects, occupational health and safety is often ignored with the classic reason by business owners that the costs for occupational health and safety for workers are considered expensive. As is the case with PT. Cahya Indah, which is a company engaged in the construction sector with a large work capacity, it is fitting that the Occupational Health and Safety of workers be considered. Implementation of Occupational Safety and Health (K3) carried out by the construction sector. One example of construction sector activity is at PT. Beautiful Light. PT Cahya Indah is one of the companies in Indonesia engaged in construction. Where this company is engaged in the Rigid Pavement Road Preservation Project Tripe Lamongan Gresik. The road in this project has a long span of 16.5 km, located at stations 27 + 440 - 35 + 100 KM located on Jalan Raya Babat - Lamongan - Gresik, East Java. This study uses the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) method. HIRARC is a process of identifying hazards that can occur in both routine and non-routine activities, which is then carried out by an assessment process based on the identified hazards or risks to determine the high or low value of a risk so as to assist in the control process. In its preparation, HIRARC is divided into 3 stages including: hazard identification, risk assessment, and risk control

Abstract

A construction project always requires project resources as a component in the construction process. There are five project resources, namely workers, methods, tools, costs and materials. Of the five components, material is one of the main raw materials that has a considerable influence in determining the cost of the project. There are various kinds of materials, one of which is reinforcing steel. Reinforcing iron has a high enough value so that this material must be calculated very carefully in order to get the optimal iron value. Because it has a high enough value in the process, it is necessary to plan the calculation of the iron. Starting from the calculation of the need for reinforcing steel. There are several methods to calculate the need for reinforcing steel, namely the (manual) approach method and the Bar Bending Schedule (BBS) method. Bar bending schedule (BBS) is a planning method for steel work which contains detailed information in the form of the shape of the bar, the length of the bar, dimensions and the amount of bar to be used in structural work. BBS produces iron requirements in units of rods which then produce units of weight. Where in this project the process has not used the BBS iron calculation method. Where in manual calculations it does not pay attention to the pattern of iron pieces, so iron cutting in the field has not optimally utilized the remaining pieces or waste material. In this study, researchers will make iron calculations using the bar bending schedule method and make iron cutting patterns drawn per floor on a floor plan with detailed lengths and the amount of iron to be used, taking into account the remaining or waste material referring to the RKS and Shop Drawings. used in the Cita Hati School Building Development Project in order to accurately obtain the results of the material requirements for reinforcing steel and the remaining iron material. By applying the bar bending schedule method, it can make it easier to supply steel materials to suit the plan. So by using the bar bending schedule in the calculation of reinforcing steel it is included in an effort to optimize reinforcement in the Cita Hati School Building Development Project.

Abstract

In the implementation of a project sometimes it does not go well, because there are obstacles that hinder the existing work. One of the obstacles that are often encountered in the field in the Tanjung Perak Diamond Pier Structure Strengthening project in Surabaya is uncertain weather conditions, this is because in carrying out the initial planning the planners did not consider the weather conditions that would occur during the implementation of this project. The impact that arises due to this delay is the increase in the duration and budget for the implementation of the project. So that in overcoming this, rescheduling is carried out which is expected to produce a logical and realistic schedule as well as costs that are as expected. The purpose of this study is to calculate the results of the costs needed in implementing the project after rescheduling. This type of research is analytic in nature. Data collection in the form of secondary data such as schedules and Budget Plans (RAB) is carried out by directly requesting the required data from related parties, then evaluating the initial costs, followed by preparing new costs using Microsoft Project tools using the Critical Path Method (CPM)). The results of this study obtained a total rescheduling fee of Rp. 28,535,441,605, there is a difference in costs of Rp. 6,482,544,691.1 of the initial planned cost of Rp. 35,017,986,296.10
