Abstract

Climate change that is happening at this time affects the decrease in the availability of water in the world. Urban areas, especially coastal areas, will have a more significant impact on water scarcity. Coastal areas in Indonesia, such as Bandar Lampung City, are mainly concerned in this study. Therefore, a study was conducted to determine the variables that influence water conservation practices in Bandar Lampung, which focuses on social psychological factors with four independent variables. By knowing the independent variable that has the highest level of influence, an approach to conservation efforts at the individual level can be approached. Data were obtained using a closed questionnaire with answer options using a Likert scale. Data analysis used simple linear regression and stepwise regression. The simple linear regression results show that the variable social norms (X4) are the highest variable with a value of R2 0.0385. In stepwise regression, the variable attitude towards conservation (X1), the benefits obtained (X2), individual control behavior (X3), and social norms (X4) simultaneously have a coefficient of determination value of R2 0.06127, where the social norms variable align with sample linear regression results on water conservation practices. These social norms can be used as a reference by stakeholders such as Perumda, Regional Government, NGOs, etc., through individual approaches in mapping strategies for increasing water conservation practices.

Abstract

Fire accident onboard RoRo (Roll on/Roll off) passenger ferry notoriously indicates intense symptoms of human, technical and organisational issues. In some cases, the more complex the fire's origin, the more challenging the crew would handle handling, suppressing, and putting out the fire. The crew response plays a significant role in the success of firefighting onboard. The research focuses on evaluating the effectiveness of fire drill performance by developing an evaluation model based on the cognitive model and analytical network process. The model was developed to overview crew performance and consistency in conducting fire drills on board the roro passenger ship. The questionnaire is developed to obtain crew perspective and awareness of fire risks. The analytical network process (ANP) model is utilised to identify crew preference during fire drills. The result of decision-based research identified significant issues that occurred in every step of cognition. Competency and proficiency of the crew, along with continuous training and familiarisation, were the main issues in improving effectiveness in firefighting. The results of the analysis were resourceful evidence to enhance audit and supervision for the emergency preparedness system. In addition, it is also a reference for developing further training models to improve crew overall performance in firefighting.

Abstract

The advancement of ship production technology in Indonesia involves the implementation of modern techniques integrating computer-based design and production facilities, such as Computer-Aided Manufacturing (CAM) for operating production machines utilizing Computer Numerical Control (CNC). One specific type of CNC machine utilized in ship production is the plasma cutting CNC machine. Despite being crucial to production, these machines frequently encounter failures that impede the production process. Through prior failure analyses conducted by the company, it has been identified that the dust collector air hose component exhibits the highest failure rate with six distinct failure modes. This article conducts qualitative and quantitative analyses of the causes of failure in the air hose dust collector of CNC plasma cutting machines using the Fault Tree Analysis (FTA) method. FTA is employed as a method to ascertain the fundamental causes of the event. The analysis results are utilized to provide recommendations for controlling objectives related to occupational safety. Six failure trees are generated, comprising a total of 28 basic causes. The most frequently occurring types of basic causes are associated with workers, methods, and materials. The probability of occurrence for the minimal cut set of each failure tree has been successfully computed. These calculations reveal that all top events possess probability values exceeding 76%. Specifically, the event of the dust collector air gap breaking has the highest probability value, reaching 99.88%, which is a composite of 15 basic causes. Control recommendations are provided in the form of substitution, engineering solutions, and administrative controls.

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

The mutual interaction between humans and animals in the field of ethnozoology includes uses that can be oriented toward conservation or exploitation efforts. However, excessive abuse of sea turtles (Chelonioidea), especially in the direction of exploitation, has led to population decline and threatened their extinction. Observations in the Derawan Island community, Berau Regency, show a decrease in the number of turtles coming to lay their eggs due to overexploitation. To overcome this problem, it is necessary to carry out research that looks for factors that influence attitudes and behavior in using turtles, including the level of ethnozoological knowledge and family economic status. This research uses a quantitative approach with an analytical correlational design and applies Path Analysis. The results of the analysis show that the level of ethnozoological knowledge has a significant influence on attitudes, with a path coefficient of 0.298 in block-1. In block-2, the results of the analysis show that the level of ethnozoological knowledge directly influences turtle utilization behavior with a path coefficient of 0.313. In conclusion, the level of ethnozoological knowledge has a dominant role in shaping turtle utilization behavior in Derawan Island

Abstract

Abstract The depletion of fossil fuels is one of the reasons for using alternative fuels such as biodiesel fuel. However, biodiesel has disadvantages such as higher density, lower heating value, high fuel consumption, and high nitrogen oxide (NOx) content compared to diesel. To improve this, it can be done by increasing the cetane number of the fuel by adding citronella (C) oil as a bioaditive. The purpose of this study is to determine the characteristics of biodiesel fuel after adding citronella oil, and to determine the effect of citronella oil addition on engine performance, vibration, noise and emissions. This research was conducted experimentally by adding citronella oil with variations in composition of 0.5%, 0.75%, 1%, 1.25%, and 1.5% of the volume of Biodiesel fuel (B30). The fuel was tested on a Yanmar single-cylinder diesel engine. Experimental results showed that the cetane number increased with the addition of citronella composition, with the highest cetane number in B30+C 1.5% fuel, which increased by 25.9% when compared to the cetane number of B30. From the performance test results, the diesel engine experienced an increase in performance in the form of power, torque, BMEP, as well as a decrease in vibration and noise when compared to B30 fuel. The lowest NOx emissions occurred at 2000 RPM with the largest load produced by fuel that had added citronella 1.5% with a decrease of 21.6% when compared to B30 fuel.

Abstract

The Application of the Marine Pollution (MARPOL) Annex IV regulation concerning sewage discharge from ferry ships operating on the Ketapang-Gilimanuk route plays a crucial role in pollution prevention. However, this essential role has been compromised due to suspicions that sewage waste from the Ketapang-Gilimanuk ferry ships is being directly discharged into the sea. Additionally, it is believed that the lack of sewage storage facilities at the port and inadequate supervision by local port authorities contribute to this issue. This research aims to investigate the implementation of MARPOL Annex IV in pollution prevention on ferry ships along the Ketapang – Gilimanuk route using the Analytical Hierarchy Process (AHP) method. This method is employed to establish a comprehensive evaluation framework by considering criteria such as safety management systems, safety and environmental protection policies, Company responsibilities and authorities, cultural and behavioral aspects, organizational factors, and technical considerations. Data will be collected through surveys and interviews with ship operators and members. Economical is more priority than operational techniques because it is related to capital expenditure and operational costs of each alternative to prevent marine pollution. Operational techniques are more priority than safety and environment because they are related to the technical and operational of each alternative to preventing marine pollution. Regulations are more priority than safety and environment because regulations affect each alternative, both Indonesian regulations and also SOPs at ports.

Abstract

Indonesia is a maritime country with vast marine areas. Furthermore, Indonesia is also a country with the second-largest biodiversity in the world. Many endemic flora and fauna in Indonesia, some even endangered, are vulnerable to becoming illegal trade commodities, primarily through domestic and international sea routes. Therefore, endemic flora and fauna in Indonesia must be protected to prevent extinction. Customs is a community protector that monitors export activities through the law enforcement of CITES (Convention on International Trades on Endangered Species of Wild Flora and Fauna). This study aims to analyze the effectiveness of supervision carried out by Customs as a community protector in monitoring illegal wildlife exports through the prohibition and restriction supervision scheme at Tanjung Priok Port. The method used in this paper is qualitative research with a literature study approach. Based on the results of the data analysis that has been carried out, it can be concluded that customs have an essential role in the export of protected flora and fauna. For the supervision carried out by Customs to be effective and maximum, several steps are needed, including no collusion, computerization of services provided, and finally, implementing situational crime prevention against illegal wildlife trade.

Abstract

In the operation of a multipurpose terminal in a port (terminal that can serve and be berthed to more than one type of a ship), the position of planning an optimal berth allocation for ships is essential to maintain. Berth allocation planning (BAP) is considered tactical planning that can impact the performance of a terminal and the cost of a ship in a port. That is because the longer the waiting time of a ship that waits to be berthed, the smaller number of ships will be served by the terminal, and the higher the cost will be borne by the ships. This paper, based on a case study in Terminal Jamrud of Tanjung Perak Port of Indonesia, will discuss a Mixed Integer Linear Programming (MILP) mathematical model of a BAP to minimize the ships’ waiting time to berth with consideration to the tailored conditions of the multipurpose terminal. The results show that the optimization model yielded reductions in the datasets 1 to 3 tested on the North/West and 4 to 6 on the South pier. There are savings in the waiting time reduced in hours, which are 403 (12,82%), 189 (26,18%), 418 (30,74%) for the North/West pier and 34 (16,43%), 1663 (88,13%), 475 (46,75%) for the South pier.
