Abstract

The vehicle terminal is a special port for loading and unloading vehicles in the form of Completely Built Up (CBU), Trucks, Heavy Tractors, and spare parts. In Indonesia, there is the second largest vehicle terminal gate in Southeast Asia, namely the Tanjung Priok Vehicle Terminal. The export of Indonesian vehicles through Tanjung Priok reached its highest point in 2018, amounting to 264,533 units. Meanwhile, the vehicle import policy in Indonesia is not supported by building a manufacturing center which will reduce the country's dependence on car imports. So it is necessary to analyze the height of the accumulation field of the Tanjung Priok Port International Vehicle Terminal in order to meet the increasing number of vehicles. In this research, it examines the risk of vehicle terminal buildup field and vehicle terminal operation management authority in order to reduce the number of piling field requirements. The data analysis of the stacking field uses a multivariate regression model to review the predicted increase in the number of vehicles until 2030. Meanwhile, the frequency analysis uses the monte carlo simulation to obtain a more effective time duration in vehicle terminal management. The results of the accumulation of field data analysis for important criteria are still sufficient. Meanwhile, the criteria for export and total criteria are not sufficient for 2026 and 2030, respectively. The results of the analysis show that the change in the area of the dumpsite is smaller due to the effectiveness of terminal vehicle management time.

Abstract

Occupational Safety and Health (K3) has been regulated in national regulations and international standards such as OSHA, but BPJS Ketenagakerjaan reported that cases of work accidents increased from 3,174 in 2022 to 5,508 by August 2024. The construction project of the Pentecostal Church Building in Kuta, with an K3 budget of only 0.25% of the project value of IDR 7,444,833,207.00, is below the standard set by the Circular of the Director General of Construction Development in 2018 of 1% to 2.5%. This study aims to identify risks using the Job Safety Analysis (JSA) method and examine the appropriate K3 cost estimates. Primary data is in the form of the number of workers, while secondary data is taken from project documents such as time schedules, planning drawings, Bill Of Quantity (BOQ), and AHSP Badung Regency. Risk analysis is carried out with JSA, identifying work, hazards, and risks using a risk matrix. The K3 cost estimate is calculated from the need for PPE, training, and other K3 facilities, then compared to the total project value. The results of the study showed that 7.27% of risks were identified as very high, 50.91% as high, 40% as medium, and 1.82% as small. The estimated K3 cost required is Rp145,082,002.07 or 1.9% of the project value.

Abstract

This research discusses the planning of Reach stacker routes in the Ex-JICT 2 Container Yard area of the Tanjung Priok Port, PT Pelabuhan Indonesia. The background of this research is the increasing need for port efficiency to support domestic and international goods distribution. Reach stackers were chosen due to their flexibility in moving containers, however, the movement of this equipment requires routes that meet standards to ensure safety and efficiency. This research uses a structural design method for port pavement designed to withstand Reach stacker loads for 20 years using Interpave, British Precast Standard. The analysis includes wheel loads, wheel proximity factors, dynamic loads, and optimal pavement thickness. The results show that C35/45 concrete material is more recommended than C32/40 with a fiber steel mixture and C8/10 CBGM pavement with CBP, as it has higher compressive strength and better resistance to heavy loads.

Abstract

Gerokgak Reservoir in northern Bali plays a key role in supporting irrigation for Subak Gede Gerokgak. However, ongoing sedimentation threatens its storage capacity and long-term performance. This study evaluates the sedimentation risk management plan by Balai Wilayah Sungai (BWS), focusing on the effectiveness of the current dredging schedule and storage allocation. Using the Universal Soil Loss Equation (USLE) with land use, topographic, and rainfall data, the annual sediment yield was estimated at 29,277.85 m³, with a Sediment Delivery Ratio of 18.6 percent. Comparison with historical data showed only a 3 percent margin of error. Without additional dredging, dead storage is projected to be filled within 8 years, far before the 20-year target in the current plan. To meet that target, 0.59 million m³ of storage is needed, requiring 0.299 million m³ of extra dredging. These findings underscore the need to integrate sediment yield analysis into planning for more adaptive and effective reservoir management

Abstract

Earth excavation work cannot be separated from the use of heavy equipment, where job performance is expected to be completed in a fast time at a minimum cost. Thus, it is necessary to calculate tool productivity to determine the combination of heavy equipment usage in a job. The productivity of heavy equipment can be determined based on the cycle time of working tools, where the cycle time of each tool has a difference depending on the size of the tool and the type of material being worked on. The method used by comparing productivity between heavy equipment is calculated by observing the cycle time of heavy equipment in completing the work. The productivity comparison obtained is used to calculate the most efficient tool requirements in a job which then calculates the costs that need to be incurred to complete a job. In this case, the efficiency of the combination of heavy equipment fleets can be done if the productivity between tools is far enough adrift. This efficiency value can affect the length of working time or equipment costs, or both. In this study, the efficiency of heavy equipment in the earth excavation work of the Cijurey Dam inlet area can be done through changes in the combination of heavy equipment fleets which originally used two excavators and four dump  trucks to three excavators and four dump trucks. The results of heavy equipment efficiency show an acceleration of work time and a reduction in cost expenditure, the new fleet change of heavy equipment is using fleet 3 which can streamline time up to 80 working hours and reduces costs by Rp97,543,226.67.

Abstract

The Bili-Bili Reservoir serves multiple purposes, including flood control, raw water supply, irrigation, and hydropower generation. In 2021, significant discrepancies were observed between the Annual Reservoir Operation Plan (AROP) and the actual Reservoir Operation Pattern (ROP). during the first 15 days of December 2021, the AROP targeted a rest water level (RWL) of +77.34 m with a planned discharge of 20.27 m³/sec. In contrast, the realized RWL reached +92.35 m with an actual discharge of 45 m³/sec. This study aims to analyze the causes of these differences and compare the reservoir operations outlined in the AROP with those reflected in actual utilization, using an operational pattern simulation based on variations in irrigation water requirement (IWR). Analysis using a dependable flow of 80% shows that the total IWR in the AROP is only 69% of the IWR calculated from actual reservoir utilization, likely due to declining inflow trends and an operational pattern that adjusts to inflow magnitude and rainfall. Meanwhile, the realized IWR is 32% greater than the utilization analysis and 91% greater than the AROP, indicating that the reservoir released more water than planned, following actual inflow conditions. This study highlights the need for more adaptive reservoir operation planning to ensure effective water resource management.

Abstract

: I Gusti Ngurah Rai International Airport is one of Indonesia’s primary air transportation gateways, which has experienced a significant increase in passenger mobility following the Covid-19 pandemic. With the rising number of arriving passengers, the demand for ground transportation to and from the airport has become a crucial aspect of travel connectivity. This study aims to analyze the characteristics of transportation mode users, the probability of selecting taxis and rental transportations, as well as the optimal fleet requirements at I Gusti Ngurah Rai International Airport. The research employs a stated preference technique with a binary logit difference model analysis. Primary data were obtained through surveys of domestic passengers and ground transportation drivers in the domestic arrival area, while secondary data were collected from various relevant agencies. The results indicate that the probability of users choosing a taxi is 2.32% and that of choosing a rental transportation is 3.86%. Consequently, the projected requirements are 27 taxi units and 44 rental transportation units in 2025, 30 taxi units and 51 rental transportation units in 2030, and 35 taxi units and 58 rental transportation units in 2035, based on the demand level of domestic flight passengers. The number of taxis and rental transportations currently available at I Gusti Ngurah Rai International Airport exceeds the projected fleet requirements.

Abstract

An increase in population by 1.04% and crop area by 14.08% in Bali Province, will also increase the water needs. Dam as water infrastructure that supports water availability, is needed in overcoming the problem. Dams require operation and maintenance (O&M) to keep function optimally. Operation and maintenance costs need to be evaluated periodically with the real needs of operation and maintenance. Real needs of operation and maintenance suitability can guarantee the optimal functioning of the dam. This study evaluated the suitability of Balinese dam’s operation and maintenance, namely Benel Dam, Telaga Tunjung Dam, Gerokgak Dam, and Palasari Dam. Dam performance appraisals include physical, operational security, and institutional ranging from 0 to 100. The results the grouped into good, enough, less, and bad category. All four dams got “enough”, so their real needs number for operation and maintenance need to be evaluated. The evaluation showed that Gerogkak Dam had the largest real needs number for operation and maintenance value, which is IDR 28,767,099,149. The real needs of operation and maintenance value is consisted of ≥ 90% dredging’s cost. Dredging’s cost us mainly influenced by sediment’s volume. So, to reduce sediment’s volume and improve dam’s performance for irrigation, it is necessary to increase the efficiency of dam’s operation and maintenance. Efficient dam operation also necessary due to the limited operators. Building efficiencies that control sediment and water supply, must be increase aligned with water needs and reservoir conditions.

Abstract

Slope instability is a major geotechnical challenge in coastal and soft ground areas, often leading to structural damage and safety hazards. This study presents a numerical analysis of slope stability in Tanjung Batu, East Kalimantan, focusing on the effect of using Corrugated Concrete Sheet Pile (CCSP) as a slope reinforcement system. The analysis was conducted using PLAXIS 2D, applying the finite element method and strength reduction technique to evaluate changes in safety factor due to the installation of CCSP. The results show that the implementation of CCSP reinforcement significantly improves the slope's factor of safety, indicating increased stability under site-specific loading and soil conditions. In addition, deflection and structural performance evaluations of the selected sheet pile type (CCSP W-400) reveal that the maximum bending moment remains below both the cracking and ultimate moment capacities, confirming the adequacy of the structural design. This research demonstrates that CCSP is not only effective in improving slope stability but also structurally reliable under expected field conditions. The findings support the use of prefabricated concrete sheet piles as a practical and efficient solution for slope stabilization in similar geotechnical environments. Further studies incorporating field data and long-term performance monitoring are recommended.

Abstract

Clashes between objects in construction projects often lead to delays, increased costs, and rework due to a lack of coordination between disciplines and the limitations of traditional clash detection technologies. This study evaluates the effectiveness of implementing clash detection based on Building Information Modeling (BIM) using Autodesk Revit and Navisworks in reducing rework, additional costs, and project duration. The research adopts a quantitative method using secondary data, including 3D models, time schedules, and Unit Price Analysis. The analysis identified a total of 964 clashes, consisting of 274 structure-MP clashes, 603 architectural-MP clashes, and 87 structure-architectural clashes. The implementation of clash detection resulted in a rework reduction of 0.34% and a total cost saving of 4.63%, which includes savings in structural work (0.08%), architectural work (7.76%), and mechanical-plumbing work (0.06%). Avoided rework includes the demolition of 4.93 m³ of concrete, 70.81 m² of walls, 1051.11 m² of ducting relayout, and 1.05 m of pipe relocation. Additionally, the potential time saving is estimated at 41.7 days or 7.79% of the total project duration.
