Abstract

Biaya dan waktu merupakan dua faktor yang berbeda dalam pelaksanaan konstruksi. Terkadang, dalam upaya untuk mempercepat waktu pengerjaan, beberapa pihak mungkin mengabaikan biaya, sementara yang lain mungkin lebih memperhatikan efisiensi biaya. Untuk menentukan pendekatan yang tepat, diperlukan pertimbangan menyeluruh terhadap semua faktor yang mempengaruhi biaya dan waktu. Metode yang digunakan untuk melakukan analisis ini adalah dengan melakukan perhitungan langsung menggunakan aplikasi Microsoft Excel, dengan mengacu pada gambar denah aktual dari data proyek untuk mengukur dimensi, luas, dan volume bangunan. Data tersebut kemudian dimasukkan ke dalam Microsoft Excel untuk dianalisis. Selanjutnya, Analisis Harga Satuan Pekerjaan dibuat berdasarkan Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat Tahun 2016 dengan menggunakan harga dasar yang telah ditetapkan. Jumlah pekerja dan biaya upah pekerja yang digunakan dalam metode plat bondek dan metode plat konvensional dianggap sama. Hasil analisis menunjukkan bahwa biaya untuk pelaksanaan plat konvensional sebesar Rp.5.638.250.747,87, sementara biaya untuk plat bondek adalah Rp. 3.881.484.523,79, dengan selisih sebesar Rp. 1.756.766.224,09. Dari segi waktu, metode pelaksanaan plat konvensional membutuhkan 71 hari, sedangkan plat bondek hanya membutuhkan 41 hari. Oleh karena itu, metode pelaksanaan plat bondek lebih cepat, dengan perbedaan waktu sebesar 30 hari dibandingkan dengan metode plat konvensional.

Abstract

The construction of the Simoro Water Treatment Plant (WTP) in Gumbasa District, Sigi Regency, Central Sulawesi, is a complex project aimed at improving regional infrastructure. This research aims to analyze the construction management of the project by applying the Critical Path Method (CPM) and Time Cost Trade Off (TCTO) methods to enhance time and cost efficiency. The CPM method is used to identify the project's critical path and manage activities that most affect the total project duration. Meanwhile, TCTO is analyzed to optimize the additional costs needed to accelerate project completion without compromising the quality of the final results. The research results indicate that: (1) using the CPM method and Primavera software, the activities on the critical path include Start (Preparation), Cleaning and leveling work, Earth excavation work, Aggregate Base Layer B work, Earth excavation work, Aggregate Base Layer B work, Cut and Fill work, Bore Pile work (Reservoir), Earthwork (Reservoir), Pile Cap Foundation work (Reservoir), Concrete Floor work, Reservoir Tank work, Bore Pile Foundation work for Clearwell, Bore Pile Foundation work for IPA Building, Earthwork for IPA Building, Structure work for Coagulation Building, Structure work for Flocculation Building, Structure work for Sedimentation Building, Mechanical work, Electrical work, Scada Instrument, and Commissioning Test. (2) From the application of Time Cost Trade Off (TCTO) analysis, the lowest implementation cost obtained is Rp. 78,262,088,288.34 with the Crash condition of the implementation time being 913 days. This research provides significant contributions to improving construction management performance, particularly in terms of time and cost efficiency, and offers practical guidance for project managers in developing better and more effective project management strategies.

Abstract

This study analyzes the relationship between time and cost control in the relocation project of community roads affected by the Bulango Ulu Dam in Gorontalo Province using the Line of Balance (LoB) method. This method is applied to design a more structured work schedule, identify activity stages, and minimize potential conflicts between tasks. The study results indicate that implementing the LoB method reduces the project duration to 33 weeks (7.7 months), compared to the existing schedule of 35 weeks. The two-week time savings significantly improve time efficiency. However, this acceleration results in an increase in total project costs, primarily due to higher labor and equipment usage. Calculations show that the LoB method requires higher costs than the existing schedule. This study confirms a reciprocal relationship between time and cost: time acceleration can affect cost increases, but cost efficiency can also be achieved through more targeted planning. The application of LoB provides a more measurable solution for managing construction projects, especially those involving repetitive tasks. The success of this method depends on strict supervision and schedule adjustments based on field conditions

Abstract

This research aims to examine the application of green construction principles in construction management, with a case study on the construction project of the Governor's Office of West Sulawesi Province. The method used in this research is Importance Performance Analysis (IPA) to assess the performance and importance of green construction attributes, and SWOT analysis to formulate performance improvement strategies. The results showed that the performance level of green construction implementation reached 93%, which indicates that the existing performance needs to be maintained but also requires some improvement in certain aspects with the percentage of conformity level, namely the provision of green open areas 87%, environmentally friendly energy innovation 87% and water management 87%. From the SWOT analysis, internal factors have a value of 2.34 and external factors 2.41, which places this project in quadrant I, signaling the potential for aggressive development. Recommended strategies include strengthening green technology innovation and resource optimization through cooperation with external parties (SO strategy), as well as resource optimization and review of sustainability initiatives (WT strategy). With the implementation of these strategies, it is expected that green construction on this project can significantly contribute to operational efficiency and environmental sustainability. This research also encourages government policies to make green construction a standard in tendering construction projects to support sustainable development in Indonesia.

Abstract

This research aims to evaluate the implementation of the Construction Safety Management System (SMKK) on the Kemiri-Depapre (MYC) Road and Bridge Construction Project in Jayapura Regency, Papua Province. The research results show that the implementation of SMKK in this project has generally gone well and is in accordance with statutory regulations, namely PUPR Ministerial Decree No. 10 of 2021. Internal audit carried out at PT. Brahmakerta Adiwira as the construction implementer demonstrated compliance with safety, health and security standards. Independent variables such as awareness of the importance of K3, K3 training, and K3 supervision have a significant contribution to the level of implementation of SMKK and the frequency of work accidents. Based on the Adjusted R-Square value, simultaneously the influence of the independent variable on the dependent variable varies between 46.60% to 96.30%. Individually, 83.33% of independent variables have a significant effect on the number of work accidents, 5.56% have a significant effect on project efficiency and productivity, 44.44% have a significant effect on the quality of implementation and work results, and 55.56% have a significant effect on the level of worker satisfaction with the implemented safety program. Implementing a good SMKK not only guarantees safety for workers but also provides economic benefits, maintains the image of the organization, and increases productivity and quality of construction work. It is hoped that this research can become a reference for construction industry players in increasing the implementation of K3 on their projects..

Abstract

Construction projects consist of several work items and require resources to achieve the success of project work including materials and costs. The material required in large quantities in the implementation cannot always be fulfilled by one material source alone, therefore several material sources are needed so that the material demand needs can be met. Especially if it consists of several project locations and must be fulfilled by several material sources. This study aims to minimize the distribution cost of class A LPA material from the source of material collection, namely in Konaweha, Pondidaha and Moramo to the Ameroro Dam Access Road project site (Package II), namely the Entrance to the Dam Segment 1, Segment 2 and Segment 3. The results obtained by implementing the North West Corner Rule and Loop Construction methods can minimize the cost of material distribution from the initial solution of Rp. 1,887,700,000, - to Rp. 1,849,500,000, - so that the difference in cost reduction is Rp. 38,200,000, - with a minimum cost percentage of 2.02%.
