Abstract

The ship's service speed performance is prioritized in a ship's propulsion system planning. Motor Vessel. KENDHANGA NUSANTARA 6 is a type of containerized cargo ship built to support the sea toll program in the Tanjung Emas port area, Semarang. The less significant propeller pitch affects the ship's ability to move. The experiment was carried out by operating the machine with maximum capability. The phenomenon of the geometric shape of the propeller provides information on the rotation results and the distribution of the working forces. The structure of the propeller design describes the ability and level of effectiveness when the propeller is submerged in water. The results of this study show that the optimization value of the right propeller pitch is 0.6%, the pitch width is 1660 mm, and the optimization value of the left propeller pitch is 1.2% with a pitch width of 1670 mm; this value can make the ship's rate speed during the docking trial 12.3 knots, following the planned speed.

Abstract

Ship stability is a critical factor in the operation of a catamaran, especially when facing various sea conditions. The catamaran H-192, recently acquired by PT XY, is used as a case study in this research to assess its stability and response to operational and environmental conditions. Stability criteria based on Annex 7 of the High-Speed Craft (HSC) Code are used as the evaluation standard. This research aims to evaluate the stability and response of the catamaran H-192 under various operational and environmental conditions. The primary focus is to ensure that the vessel meets and exceeds the stability criteria set by Annex 7 and to understand how the vessel behaves in real-world situations. The methods used in this research include stability calculations based on Annex 7 and model design using Maxsurf software. The calculations involve the analysis of the righting lever (GZ), metacentric height (GM), and other stability criteria. Operational data and load distribution are analyzed to determine the draft, trim, and stability of the vessel under various loading conditions. The results show that the catamaran H-192 not only meets but also exceeds the stability criteria set by Annex 7. The high values of righting lever (GZ) and metacentric height (GM) at various angles of heel indicate excellent transverse and longitudinal stability. The evaluation of intact stability criteria shows that all parameters achieve "PASS" status, indicating the vessel's capability to handle combinations of heeling forces due to wind, high-speed maneuvering, and passenger crowding very well. The analysis of both full and empty operational conditions shows balanced load distribution and maintained stability.

Abstract

Unsafe worker behavior remains a prevalent issue leading to workplace accidents, particularly within companies specializing in services for head truck operations, maintenance, and lifting equipment. This study aims to enhance worker safety behaviors through proactive interventions utilizing behavioral observation and intervention (BO&I). Additionally, trend analysis is employed to predict the impact of interventions on worker safety behaviors. Mechanical workers involved in lifting and transport equipment operations are surveyed as respondents. The findings reveal a notable increase in the percentage of safe behaviors post-intervention compared to pre-intervention levels. Moreover, disparities in worker safety behaviors between pre- and post-intervention stages are identified, particularly in work stages associated with a high frequency of accidents. Trend analysis forecasts that the maximum percentage of safe worker behavior will be observed at the 91st intervention. Furthermore, binary logistic regression analysis indicates that variables such as age, tenure, utilization of personal protective equipment (PPE), and education significantly influence worker behaviors.

Abstract

The development of the crossing transportation industry is currently increasing in the island areas. The use of Ro-Ro type ferry boats is extremely efficient in moving people, goods, and vehicles. The current research focuses on the damage stability of the 500 DWT Ro-Ro ferry, which aims to meet the needs of the Ro-Ro ferry in the archipelago area. The previously existing initial design of a barge hull with a main size Lpp = 40.15 m, B = 12 m, H = 3.2 m, and T = 2.15 m was used to analyze the damage stability condition further. First, the drawings were redrawn. Then, 3D modeling was performed and the tanks were inspected. The processing of the input data design was finally tested under several criteria based on damage stability in SOLAS 2009. This study concluded whether the 500 DWT Ro-Ro ferry design is acceptable considering damage stability. The GZ value is standardized in the scenario of calcge stability of the Ro-Ro ferry as a whole. Attention should be provided to the range of positive stability in intermediate stages considering the forward damage case, wherein the ship departs and the full load experiences failure.

Abstract

This study comprehensively assesses safe loading conditions for the Self-Propelled Crane Barge (SPCB) Deck Crane by integrating detailed hydrostatic calculations with righting-arm (GZ) curve analysis. At the designated summer draft of 2.75 m, baseline parameters—displacement (1 716 t), centre of buoyancy (KB = 0.765 m), transverse metacentre (KM = 2.780 m), and metacentric height (GM = 1.23 m)—were established from the vessel’s stability booklet. Four loading scenarios (lightship, full ballast, crane at maximum outreach, and cargo distribution) were defined, with updated displacement and vertical centre of gravity (KG) values used to recompute hydrostatic parameters (BM, KM, free-surface corrections) and generate full GZ curves. Intact-stability criteria (GM >= 0.15 m, area under GZ curve >= 0.08 m·rad, angle of vanishing stability >= 25°, and GZmax >= 0.25 m) were evaluated for each case. Results indicate that the ballast condition yields the highest stiffness (GM approximately equal to 1.50 m) and energy absorption (AUC approximately equal to 1.15 mrad). The crane-outreach scenario represents the narrowest margin (GM approximately equal to 0.90 m, AUC approximately equal to 0.60 mrad). A safe-loading envelope was developed, showing permissible crane loads of up to 100 t at 10 m outreach and limiting lifts beyond 20 m to 50 t or less. Mitigation measures—ballast management, outreach/load restrictions, optimized cargo stowage, and real-time monitoring—are recommended to ensure regulatory compliance and operational safety.

Abstract

We evaluated the sustainability and feasibility of sanitation systems on passenger ferries operating in Semarang. Sanitation plays a vital role in maintaining public health, ensuring passenger safety, and supporting sustainable maritime transportation. This study employed a descriptive approach, relying on field observations and a literature review to assess sanitation conditions based on applicable health regulations and maritime standards. Evaluation focused on the availability of clean water, sanitation facilities, waste management systems, and the presence of disease vectors such as rodents. The results indicate that existing sanitation systems do not fully meet sustainability and health standards, particularly regarding waste management practices and vector control. It highlights the need to improve sanitation management through better maintenance practices, the application of appropriate waste treatment technologies, and increased awareness among ship crews. Findings contribute to bridging knowledge, technology, and society in achieving sustainable development, particularly in improving public health and resilience within maritime communities.
