Abstract

Dalam proyek konstruksi gedung bertingkat, terdapat pihak – pihak yang terlibat dalam jalanya suatu proyek atau bisa disebut juga dengan stakeholders. Hubungan antara stakeholders ini umumnya memiliki potensi terjadinya konflik antara satu dengan lainya seperti contohnya pihak kontraktor dengan pihak konsultan pengawas proyek. Konflik tersebut tentunya dapat mengakibatkan terjadinya berbagai risiko dalam proyek yang diakibatkan penyampaian dan penerimaan informasi yang kurang baik. Maka daripada itu diperlukan adanya analisis pengaruh komunikasi proyek terhadap beberapa risiko proyek. Analisis pada penelitian ini menggunakan analisis multivariat dengan software SEM-PLS (Structural Equation Modeling – Partial Least Squared) dengan variabel independen terdiri dari laporan kinerja, penggunaan fasilitas & teknologi, penyampaian informasi, kemampuan berkomunikasi, dan hubungan koordinasi terhadap variabel dependen risiko desain, risiko tenaga kerja, risiko sumber daya, risiko politik sosial dan risiko kontraktual. Sebagian hasil penelitian dari analisis multivariat ini sudah sesuai dengan hipotesis penelitian terdahulu, akan tetapi terdapat beberapa hasil yang berbeda dengan hipotesis yang digunakan, yaitu pada variabel hubungan koordinasi tidak berpengaruh signifikan terhadap variabel risiko desain.

Abstract

The construction project of the JLS Lot 3 Pantai Serang - Sumbersih is a concrete example of the government's efforts to enhance connectivity and infrastructure development in Indonesia. Heavy equipment such as excavators and dump trucks play a crucial role in enhancing efficiency and productivity in this project. Infrastructure development projects often encounter obstacles such as delays and high operational costs. Rain is one of the causes of those obstacles. One way to get a clear picture of the impact of rain is to conduct a comparative analysis of heavy equipment productivity before and after the rain. Evaluation of the decrease in productivity is necessary so that mitigation measures can be taken to minimize its impact on the project. This study aims to analyze and compare the productivity of excavators and dump trucks under conditions before and after rain on the JLS Lot 3 project. This study uses a quantitative method by analyzing primary data obtained through observation of the cycle time of excavators and dump trucks before and after rain in the field. The excavator's productivity before the rain was higher, at 1506.27 m3/day, compared to after the rain, at 854.33 m3/day. The productivity of the dump truck before the rain was also higher, at 259.60 m3/day, compared to after the rain, at 138.67 m3/day. The cause of the difference in productivity between the excavator and dump truck before and after the rain is the muddy and waterlogged field conditions, which lead to changes in the excavator's digging speed, per-cycle production, and the dump truck's rate while moving from the excavation site to the disposal site.

Abstract

The construction of roads plays a crucial role in supporting public mobility and economic growth. The development of the South Java Road (JLS) is one of the initiatives designed to enhance connectivity in the southern region of Java Island. On the Bululawang – Sidomulyo – Tambakrejo segment, the quality of road construction work is a top priority to ensure safety, durability, and transportation efficiency. The development of JLS is strongly aligned with the Sustainable Development Goals (SDGs), particularly Goal 17, Partnerships for the Goals, involving various parties in ensuring the success of the project. The embankment soil work is a critical aspect, as the compaction of embankment soil directly influences the stability and load-bearing capacity of the road structure. The research methodology started with a literature review, followed by secondary data collection, field observations, and compaction testing using quartz sand and a Speedy Moisture Tester to verify moisture content. The results of the sand cone test at STA 11+725 R, STA 11+750 L, and STA 11+775 R indicate that all points met the minimum compaction criterion of 95%, with field compaction ranging from 97.46% to 98.24% of the maximum dry density (MDD). Although the moisture content at STA 11+725 R was slightly outside the acceptable range, the other points met the allowable moisture content criteria. The testing was conducted in accordance with SNI 03-2828-1992 and SNI 1742-2008, ensuring that the embankment soil compaction quality meets the technical standards.

Abstract

In the world of construction projects, good project management is required, including the use of domestic products. The government encourages the use of domestic products through the program to increase the use of domestic production (P3DN). The amount of domestic content in commodities, services, and the combination of products and services can be used to measure the use of domestic products. This quantity is called the Domestic Component Level (TKDN). Company Benefit Weight (BMP) is an award given to industrial companies that invest and produce in Indonesia. This research aims to calculate the amount of TKDN and BMP for the Muhammadiyah Ahmad Dahlan Kediri Hospital construction project. With reference to the Ministry of Industry of the Republic of Indonesia's Regulation No. 16 of 2011 regarding Provisions and Procedures for Calculating Domestic Component Levels, the research employs a descriptive quantitative methodology to compute and analyze Domestic Content Levels (TKDN). The results of analytical calculations show that the TKDN percentage is 69.65% and the BMP percentage is 3%. This research concluded that the total TKDN and BMP was 72.65%, thus meeting the minimum limit for the sum of TKDN and BMP of 40%.

Abstract

Project management is managing projects by considering all aspects of construction projects. A project must run according to plan and can be completed on time, so planning is needed before a project runs; scheduling must be considered. Scheduling is an important step in determining the exact duration and sequence for each activity in the project to create a logically structured schedule that can be implemented realistically. Many methods can be applied in project scheduling, such as S Curve and CPM (Critical Path Method). The use of different scheduling methods is considered to affect the final result of scheduling. Therefore, it is necessary to analyze the two methods. The analysis was carried out by comparing the critical trajectory, duration, and cost of structural work on the Kediri Regency Stadium Design and Build Project produced by the two methods so that it can be concluded which method is more efficient. The results showed differences in critical trajectories in the S curve and the CPM methods. In addition, the difference in duration is obtained; the S curve method requires a work duration of 140 days with a cost of Rp 48,041,965,577.96. Meanwhile, the CPM method requires a work duration of 131 days at a cost of Rp 47,535,997,308.05. Based on the results, the CPM method is superior in terms of time and cost.

Abstract

Construction projects are related to infrastructure development in Indonesia, which is an important foundation for economic growth by supporting mobility, trade, and connectivity between regions. Infrastructure development also supports the utilization of labor resources in Indonesia. This research aims to analyze the availability of labor in a construction project. The Resource Leveling method is used to level the labor needs in the project. The results showed that there was an allocation of labor that exceeded the maximum daily availability before equalization. The initial allocation based on qualifications showed that the maximum number of workers consisted of 2 foremen, 1 head carpenter, 1 head ironworker, 1 head mason, 5 carpenters, 5 ironworkers, 1 mason, and 13 workers. After equalizing the workforce, the maximum number of workers required is 1 foreman, 1 head carpenter, 1 head ironworker, 1 head mason, 4 carpenters, 4 ironworkers, 1 mason, and 13 workers. This research emphasizes the importance of workforce equalization to avoid over-allocation and ensure efficiency in construction projects.
