Abstract

Ships are often used to move cargo, and their main engines are crucial. Accidents and financial losses might result from the main engine being in poor condition. Before completing maintenance, conducting a failure analysis is necessary. The existing method is static and involves using a list of failure modes from the engine's manufacturing phase. This study proposes a preliminary design of dynamic system prototype that seeks to improve ship engine monitoring of status. It includes features such as a list of failure modes and codes based on ISO 14224:2016, data collection unit worksheet, and dynamic charts for visualizing the results. Two testing iterations were performed on the prototype. First, literature data obtained from the internet was used to generate annual and monthly report charts, confirming the functionality of the prototype. Second, real data from engine failures on the tanker ship were used to ensure logical correlations among failure causative factors. The result from real data testing included Structural Deficiency (STD), External Leakage Fuel (ELF), and Breakdown (BRD) were shown. Based on these results through the prototype simulation, can be taken into consideration for the ship's crew and shipping company management to plan oil monitoring, heating the oil properly, and conduct routine maintenance check as a preventive action to reduce the impact of engine damage in the future due to Engine Breakdown and Structural Defiency.

Abstract

At the Sukodono molding company which produces Bioring cone cups using injection molding machines, a trial and error process to obtain parameter setting values on the machine is still applied in the early stages of production. This problem is detrimental to the company because they have to bear the production burden due to production delays. A solution is needed to optimize injection parameters with cycle time response. Therefore, this study proposes an analysis of the application of the Taguchi method by utilizing the signal for noise ratio to determine the influence of factors and also to optimize parameter such as temperature, pressure, and cooling time for the production process. The trial results show that the ideal blend of factors includes injection pressure parameters at level 1 with a value of 80 bar, injection temperature at level 2 in value of 225°C, and cooling time in level one with a value of 0.1 seconds.

Abstract

Bathymetric surveys nowadays are often used by the echosounding method. This method has weakness because the range that can be surveyed is limited due to cannot reach areas that have shallow depths. With advances in technology, there are alternative ways that can be done to map the depth of the sea, with the help of satellite imagery or remote sensing. This method uses a mathematical algorithm based on a combination of spectrum channels called Satellite-Derived Bathymetry (SDB). In this research, Sentinel-2 satellite imagery was used with Lyzenga algorithm. Lyzenga (2006) uses multilinear regression which is a combination of an equation that aims to convert pixel values into in-situ depth values. Within research of six locations in Bali Province, which are Sangsit Harbor, Gunaksa Harbor, Amed Port, Keramas Beach, Serangan Harbor and Sawangan Beach produced an R2 value each of 0.451, 0.747, 0.495, 0.610, 0.451 and 0.676. While the RMSE values were 26,247, 12,377, 31,942, 3,531, 3,000, and 1,992 respectively for water depths of 146 m, 97 m, 183 m, 22 m, 13 m, and 18 m respectively. The parameters that affect the level of accuracy are: water depth, presence of breaking waves, presence of disturbance objects in the waters.

Abstract

Ferry accidents in Indonesia happen not just once or twice, but more than that. This is reinforced by statistical data on shipping transportation accidents. Shifting or overturning of the vehicle to the side of the ro-ro ferry has a big hand in causing the ship to capsize, and eventually an accident occurs. This study aims to determine the characteristics of the lateral and vertical acceleration of vehicles based on their location on the car deck under the influence of side waves. The method used is strip theory with the help of Maxurf software, which adheres to the B-spiline mathematical equation. The results of the study detected that vehicle positioning on the ro-ro ferry car deck significantly affects the value of vertical acceleration and lateral acceleration due to rolling motion. This is one of the parameters that can cause a vehicle to roll over.

Abstract

Ship structure composed of stiffened plates is subjected to a variety of loading conditions during service, which can lead to buckling. As a result of panel buckling, the overall strength of the ship hull girder is reduced, which is what determines the ultimate strength of the hull girder. The ultimate strength analysis can be accomplished with finite element (FE) simulation, but detailed modeling can be time-consuming. Due to these reasons, it is more advantageous and costeffective to replace the three-dimensional (3D) stiffened panel model with a two-dimensional (2D) equivalent single layer (ESL) plate. This shift from 3D to 2D is premised on the accuracy of ESL in representing the various buckling modes of stiffened panels, which are determined by panel topology and boundary conditions. Therefore, an equivalent single layer plate (ESL) that represents a stiffened panel is evaluated in different buckling modes. Considering that ESL is asymmetric in nature, any modification of the stiffened panel's geometry has a significant effect on the buckling modes. In this paper, we are concerned with two modes of buckling: (i) local buckling within the stiffeners of the plate and web, and (ii) local lateraltorsional buckling within the stiffeners. According to the results, ESL is capable of accurately predicting the effect of local buckling in combination of biaxial compression and lateral pressure.

Abstract

Shrimp shell waste contains chitin which can be processed into chitosan. Chitosan can be utilized as an edible plastic. The film is expected to maintain food quality by resisting water vapour transfer as a preservative and maintaining odour. Edible plastics as food protectors are expected to have optimal mechanical properties. Chitosan films are brittle, so plasticizers are used to increase their flexibility. The mechanical properties of the film may change during storage time. The decline in film quality is expected to be fast enough to allow edible plastics for food wrapping. This study aims to determine the effect of glycerol addition and film storage time on the mechanical properties of edible chitosan film. From the results obtained, adding glycerol plasticizer produces films with thickness and elongation that tend to increase. In contrast, the tensile strength value increases and then decreases with the addition of glycerol. The optimal mechanical strength value was obtained in the film solution with glycerol at 0.3 mL/g chitosan with a maximum tensile strength of 200 kgf/cm2 and a per cent elongation of 135%. The thickness of the film produced was 0.17 mm. The film produced in this study has met the standards of film mechanical strength (tensile strength and per cent elongation) based on the Japanese Industrial Standard (JIS). Meanwhile, based on the Indonesian National Standard (SNI), the tensile strength value produced in this study has yet to meet the SNI standard.

Abstract

As a popular tourist attraction, the Binasi Beach ecotourism area is always busy receiving visits from domestic and foreign tourists when the holiday season arrives. However, the management of ecotourism objects is not optimal, sometimes this makes ecotourism not much visited on weekdays or on weekends. This has an impact on ecotourism activities that are not really felt by local people who depend on these ecotourism activities. The research was carried out from June to August 2023. The research used an exploratory qualitative approach. The data used uses primary data obtained through interviews with various elements and measurements of water quality and water ecology. Meanwhile, secondary data was collected from various related document sources. Data analysis was carried out using Willingness to Pay (WTP), Willingness to Accept (WTA), economic potential analysis, SWOT analysis, Reliability test and Validity test. The results of the study indicate that the development strategy can be pursued by adding supporting facilities such as providing information boards for tourists regarding directions, location of supporting facilities and the furthest water point that is safe for swimming. The addition of environmentally friendly play facilities is also highly anticipated by tourists. Creative local economic products that can be developed are Kepek Gadapang and Turtle Themed Crafts. Furthermore, the government can issue policies to provide routine guidance and access to capital for businesses run by local communities.

Abstract

An anchor handling ship is a ship designed to support offshore operations in the form of handling offshore building anchors and carrying out activities of moving objects such as FPSO, Semi-Submersible Rigs, construction, production, and barges from one place to another where it requires bollard strength. pull which varies depending on the size of the object, besides that it is also to support other activities such as exploration and drilling. The VS 491 design type anchor handling tug supply (AHTS) vessel which has been built by a shipyard in Batam has a maximum bollard pull test of 255 tons. This paper will analyze the propeller thrust, power, and efficiency propeller before and after the installation of the Rudder Bulb (RB) respectively in free-running conditions and towing barge conditions in 50% barge conditions and full loaded capacity, as well as in draft, and Speed on certain Anchor Handling ships. The resistance of the object being towed (towing) will be calculated on the load and speed of each. By using Maxsurf, software Rhinoceros 3D, dan the Numeca CFD, the shape of the ship's hull is produced according to the original. Then validation is carried out by comparing the resistance in the calculation by Maxsurf/Holtrop and the resistance in the calculation by CFD where resulting in a difference of less than 5% so that it can be said that the form of the model is in accordance with the original shape of the ship. Based on the calculation results in the free running conditions of the Anchor Handling ship, the Propulsive Coefficient (Pc) without ESD Rudder-Bulb (RB) at speeds of 10, 12, and 16.36 knots is 0.5162, 0.5407, and 0.5769 respectively, while with ESD-RB each is 0.5008, 0.5417, and 0.5921. Comparison of the Propulsive Coefficient without ESD-RB and with ESD-RB, that at speeds of 12 and 16.36 knots, the Propulsive Coefficient (Pc) increased by 0.19% and 2.58%, respectively, but the Propulsive Coefficient (Pc) decreased by 3.08% at 10 knots. Based on the analysis that has been carried out, it indicates that the installation of the Rudder Bulb (RB) will give an increase in the Propulsive Coefficient (Pc) at speeds of 10 knots and above in free-running conditions, whereas when towing it hardly gives an increase in the Propulsive Coefficient (Pc).

Abstract

the Punge Intersection is one of the four-armed unsignalized intersections in Banda Aceh City without traffic regulations such as traffic lights, roundabouts, or other warning signs. This condition is very troublesome for road users, especially during peak hours. It is considered necessary to evaluate the performance of the intersection along with alternative treatments that produce the best performance to meet the standards. Most of the previous studies relied heavily on tailor-made simulation tools to evaluate control algorithms, but the use of simulation platforms to make system comparisons through modeling is still very rare, especially in Indonesia. Analysis and modeling at the Punge Intersection using the MKJI method and PTV VISSIM 10.00-02 (VISSIM) software. Traffic volume data (plan), road geometric, and environmental conditions are needed in data processing operations using VISSIM. Three modeling scenarios were carried out with the implementation of a one-way road for arm A in the entry direction, installation of a traffic signaling tool, called APILL, roundabout planning and widening of each arm. A roundabout planning simulation with type R10-22 with widening on each road section can make the Punge Intersection with the best LOS and meet the best service levels.

Abstract

This research presents a comparative study focused on estimating the lifespan of galvanized steel pipes and stainless steel pipes within the context of a ballast system. Ballast systems play a crucial role in maintaining the stability and trim of vessels, making the longevity of the associated piping materials essential for maritime operations. This research aims to provide insights into the corrosion behavior and overall durability of galvanized steel and stainless steel pipes employed in ballast systems. The investigation involves an in-depth analysis of corrosion mechanisms specific to both galvanized steel and stainless steel pipes in the corrosive marine environment. The influence of factors such as salinity, and immersion time is examined. By understanding the distinct corrosion behavior of galvanized steel and stainless steel pipes, maritime industry stakeholders can make informed decisions regarding material selection, maintenance schedules, and potential retrofitting options. Ultimately, the insights gained from this study contribute to the sustainability and operational efficiency of maritime transport by enabling the optimization of ballast system infrastructure. As regulations and environmental considerations evolve, a comprehensive understanding of the lifespan estimation of galvanized steel and stainless steel pipes aids in mitigating potential failures, reducing downtime, and ensuring the safety and reliability of vessel operations. It is shown that the lifespan of stainless steel is longer than that of galvanized pipe.
