Abstract

This study uses a Computational Fluid Dynamics (CFD) approach. The main object in this study is NACA 4415 with slat variations. The airfoil used as the slat is Eppler 421. Reynolds number in this study is 3Í106. This study uses an unstructured mesh with a triangular cell shape with 137824 elements. The use of slats can improve the aerodynamic performance of NACA 4415. NACA 4415 without slat stalled at AoA=16º. Stall on airfoils with a single slat and double slat occurred at AoA=20º. Slat can increase Cl in NACA 4415; however, the difference in Cl increase is not much different when using a single slat or double slat. An airfoil with a single slat, on average, can increase Cl by 20.9129%. The average increase in Cl for an airfoil with a double slat is 25.6878%. Single slat and double slat increase Cd. A single slat increased Cd with an average increase of 26.1109%, and the average increase in Cd for airfoils with double slat was 54.6152%. Single slat can produce a better Cl to Cd ratio than double slat, but the optimum AoA of double slat is 1º higher than single slat. Visualization of fluid flow at AoA=16° shows the fluid flow separation in the airfoil without a slat. The fluid flow separation can be handled well when NACA 4415 is given a single slat or double slat.

Abstract

Assessment of coastline changes is crucial to coastal development and management. The Lagos coast is still prone to sediment trap and erosion to date despite the construction of the three moles to solve siltation challenges; moreover, their rates and distributions are yet to be adequately evaluated. This study examines changes along the Lagos West Mole and the possible degree of distributions along the coast between 1984 and 2018 for six epochs. Acquired Landsat imageries were processed to delineate water boundary using Modified NDWI and extract the respective coastlines from the classified waterbodies. Coastline changes were quantified using Digital Shoreline Analysis System (DSAS); the Relative Shannon Entropy (RSE) model was used to measure the degree of concentrations of accretions and/or erosions. Results revealed more profound coastal accretions than erosions; whereas RSE values portrayed dispersed accretions more than erosions. Hence, the outcomes can aid stakeholders’ informed decisions concerning coastal protection and management.

Abstract

In preliminary ship design and ship propulsion systems, it is important to have a simple method of determining the optimization of the propeller diameter and propeller efficiency, as the minimum input data to arrive at a rough estimate of performance. This problem can be solved using propeller diagrams of the open water test series or polynomial regression. This research will introduce an optimization method for the design of the B series. The propeller design process, which was carried out as a single objective function using the MatLab code numerical method, encountered problems due to cavitation, required propeller thrust and engine propeller matching. Engine propeller matching is the matching of engine power, the hull and the propeller to achieve design speed with optimal efficiency. This research focus on case study results of testing a patrol boat with a length of 60 m. By using a computer program, this 60m patrol boat is able to reach a speed of 23.5 knots using a B5-92 and an engine power of 2935 kW with an efficiency of 64.2%. Using the DESPPC program, the 60m patrol boat is able to reach a speed of 23.5 using a B5-989 and an engine power of 2927 kW with an ETA-O efficiency of 64.5%. It can be concluded that the small computer program can be used as a B-Series propeller optimization method. For future research, this method will be developed for the other series based on polynomial regression such as Gawn series and Kaplan series.

Abstract

Electrical energy has become a significant need to run the country's economy. Especially during the Covid-19 pandemic, teaching and learning activities were in the main realized at home. As a result, the national electricity demand has increased significantly. The solar power plant in the marine is also a good alternative in areas that are constrained by the lack of land as a Solar Power Plant development site. This research is motivated by the need for solar power plants using sustainable photovoltaic (PV) technology, aiming to accelerate the improvement of the quality and competence of lecturers and students in carrying out sustainable Renewable Energy (REY) research by applying the Merdeka Belajar-Kampus Merdeka (MBKM) model. The research method begins by conducting a Systematic Literature Review (SLR), which can support the relevance of sustainable REY research. The result of this research is a literature review of solar canopy PV, which is modified to be valuable in courses in the form of a sustainable REY Semester Learning Plan for one semester. From our current research, we hope that in future research, solar panel technology can not only be applied on land but also more broadly. For example, it can be applied in marine waters so that the use of solar panels can be used in many places.

Abstract

Engine emissions of ships have been highly concerned in the last decades. Most of the current ship operations worldwide are powered by the combustion engine. Advance ship powering is still on research and hard to implement directly. High cost in the application is the main issue. Meanwhile, the fuel engineering approach is proposed in the recent research to advance engine combustion, thus increasing the combustion efficiency and lowering the emissions target. This study aims to evaluate the development trend on the fuel efficiency technique to lower ship emissions. Emissions management, fuel conversion, and power conversion are the most research focus to improve fuel efficiency. However, implementing some of that research is still hard on ship operation. Technical and economic issues are the main reason. Moreover, fuel efficiency on ships is still highly based on management. Low cost, new combined fuel without separation, and less fuel treatment technology are proposed to avoid confusion on fuel consumption in the near future.

Abstract

Safety is an important aspect of the industrial process. Failure of system and mechanism endanger both human and environmental safety. Safety is obligated to be implemented precisely and thoroughly to prevent failure consequences. One of the preventive implementations is to map out safety devices in the form of SIS (Safety Instrumented System) and other layers of protection. However, to acknowledge this safety device performance used SIL (Safety Integrity Level). This final research is intended to analyze Fuel Gas systems on Onshore Receiving Facilities (ORF). HAZOP (Hazard Operability Study) as process hazard analysis with deviation during the operation so that the risk level is known. SIL verification towards SIL target is SIL-2 refer to IEC 61511 standards by FTA (Fault Tree Analysis) method. From the HAZOP study can be concluded that over-pressure becomes a top hazard to all nodes due to the most severe consequences, the highest likelihood (medium risk). The calculation result of PFDavg is Node 1 (Fuel Gas Scrubber V-6060) is 6,22E-03, Node 2 (Fuel Gas Filter Separator S-6060A) is 1,24E-03, Node 3 (Fuel Gas Filter Separator S-6060B) is 1,24E-03, Node 4 (Fuel Gas Superheater E-6060) is 1,21E-03, and Node 5 (Instrument Gas Receiver V-6070) is 2,23E-03. The conclusion of this research shows that five components of the Fuel Gas System fulfill the SIL-2 target, therefore, doing a re-design to add a safety device is unnecessary.

Abstract

Ships are sea transportation that is often used in Indonesia. However, who would have thought that the transportation would become a case because of the frequent occurrence of accidents. This has been proven from data from the KNKT (National Transportation Safety Committee) which noted that from 2012 to 2017 there had been an increase in accidents in the waters. In fact, according to the National Search and Rescue Agency (Basarnas) in 2020 there have been 878 incidents with victims reaching 4658 people. In this final project, the author makes a prototype of BNWAS (Bridge Navigational Watch Alarm System) equipped with obstacle warning using image processing with the otsu method strengthened by thresholding-based segmentation with inverse technique (TsTN), distance detection using the triangle similarity method, real-time tracking with GPS (Global Positioning System) and the entire system can be observed on the Android application. The Final Project performs several analyzes including performance analysis by calculating the accuracy of the BNWAS alarm system, image detection accuracy, distance detection accuracy, GPS accuracy, overall system testing accuracy and packet loss. The accuracy of each system is very good because the error is below 2%, while for overall system testing has a very good performance with a delay of 179.8 ms and 0% packet loss.

Abstract

Indonesia is an archipelagic country with a vast coastal area, so proper management is needed in the development of coastal areas. The city of Surabaya is one of the cities that carry out the development of coastal areas by projecting strategic areas of its coastal areas as regulated in the regional medium-term development plan 2016-2021. The strategic area of the coastal area of Surabaya city is divided into two, namely strategic areas to support economic growth and save the environment. One of the efforts to optimize the development of coastal areas is to examine changes in coastal morphology due to coastal utilization. Analysis of the study was carried out by comparing historical maps of the last 10 years with existing maps from google earth and map analysis using ArcGIS 10.8. The results show that most in the coastal area of north Surabaya there is a change in coastal morphology covering an area of 360,121 m2 as a result of the reclamation of the construction of the Lamong bay port and 623.12 m2 in the coastal area of east Surabaya due to the addition of mangroves. Regular monitoring and improvement efforts on the coast of Surabaya city must be carried out on an ongoing basis, so that coastal threats such as sedimentation and erosion can be minimized.

Abstract

This paper scrutinizes the common belief that electric vessels are economically unadvantageous. To achieve this, data of most known all-electric cargo ships (available in the internet as of 2021) was gathered and missing information was estimated with due diligence, to put together a sample selection. Sample vessels’ parameters including principal dimensions, speed and battery capacity were used to calculate their relative cargo transport efficiency. Different routes and speeds were used, as electric ships efficiency was compared to that of fuel-powered vessels. Electric ships were shown to be about 50% more profitable on short routes and equally as profitable on medium routes (if they were slow steaming), reasons being reduced crew, lower maintenance requirements and higher propulsion efficiency. However, at long routes and/or high speeds oil-powered ships currently dominate because otherwise a big part of cargo space would be allocated to transporting batteries, whose energy density is much lower than fuel among other reasons. This paper derives Electric ships design guidelines and helps make an informed decision on whether to use an electric propulsion ship on a given route.
