Abstract

Since construction sites are dangerous by nature, strict safety precautions are necessary. This study examines the Full Body Harness Pass system compliance of workers and the determinants that affect adherence with the aim of improving compliance and reducing avoidable accidents. A SWOT analysis methodology is utilized in the study to integrate quantitative compliance data with qualitative safety officer observations. Results show that though the FBH Pass system raises safety awareness, a number of issues, including poor training and reluctance to use digital tools, limit its utility. These recommendations go towards promoting an overall safer building environment, coupled with extended training programs and improved monitoring.

Abstract

This study investigates the problem of sedimentation in the Porong River and the Eastern Surabaya Shipping Lane by taking a close look at the Amphibious Multipurpose Dredger. The study examines the vessel's parameters (length: 14.30 m, breadth: 4.70 m, height: 1.60 m, draft: 1.10 m) in light of the requirements of coastal reclamation. For stability and pressure studies, manual calculations and Finite Element Method simulations are utilised. The results show that the hollow Spud design is superior to the alternatives in terms of material efficiency (Safety Factor: 12.4032). The research makes a substantial contribution by offering an effective way to address sedimentation issues through improved dredger design. Moreover, it emphasizes the crucial part that an adaptable amphibious multipurpose dredger plays in reducing sedimentation. The study highlights the strategic significance of the recommended spud design, satisfying safety regulations and improving operational efficiency, as coastal ecosystems face rising challenges. For practitioners in environmental and maritime engineering looking for sustainable approaches to the development of coastal infrastructure, this paper is an invaluable resource.

Abstract

In general, molding or FRP ship molds can only produce 1 (one) hull shape. This is of course, contrary to the production of ships which are mostly of the customize type (based on consumer demand) and very rarely in the form of mass products to produce sister ships. The high cost in the allocation of molding certainly makes economic considerations regarding the cost of shipbuilding. With the aim of a friendly fishing boat price, of course, it can make a mainstay and ease the burden on the answer to the high demand for fishing boats in the coastal community or the South Coast of Java. Multi-mold is a ship molding solution for FRP ship material that can produce more than one hull shape. This of course, will reduce the cost of producing a ship or boat. The cost budget plan is determined in detail through a survey of material prices and conducting a price determination study with an engineering estimate approach. In the multi-mold system or components, there are the main shell structure, reinforcement frame and suppot or mold holder. The shape of the multi-mold is carefully designed which can be knocked down each constituent component. The multi-mold disassembly process is accompanied by operational instructions and 3D simulation of the multi-mold assembly. The structural strength of the multi-mold components is also analyzed so that an effective and efficient multi-mold design is obtained.

Abstract

Mobile crane lifting activities carry a significant accident risk, especially when performed in tandem configurations. The main risk comes from the possibility of failure of the load cell component which plays an important role in actual load measurement. This research aims to analyze the potential failure of the load cell function in tandem lifting operations using the Fuzzy Fault Tree Analysis (FFTA) method. Data were collected through literature studies, field observations, and interviews. The FFTA method is used to identify factors that cause failure and calculate the probability of failure quantitatively. The investigation identified that the primary variables leading to load cell failure include overload situations, internal component damage, and external impacts. The highest probability of failure was recorded in the material fatigue scenario due to damage to the cable. These findings highlight the need of instituting preventative maintenance programs and conducting frequent inspections of load cell components to reduce the risk of workplace accidents.
