Abstract

The increase in ocean waste continues to grow from year to year, especially plastic and solid waste. Various ocean waste collection ships using conveyors exist, both in the form of designs and already in operation, but there has been no research on how many hulls are suitable for ocean waste collectors. This study aims to choose between the three-ship models, namely monohull type U, catamaran type inner flat hull, and trimaran type symmetrical. Assessment is based on ship resistance which relates to fuel consumption and flow distribution relates to ocean waste collection. This research uses Computational Fluid Dynamics (CFD) method which produces resistance, fluid flow velocity contours, and fluid flow patterns. Numerical simulation is based on Reynolds Averaged Navier Stokes (RANS). The turbulent model uses the standard k-epsilon equation. Then the volume of fluid sub-models used is open channel flow. The number of eulerian phases is two. Moreover,  formulation of the volume fraction parameters used is an implicit body force. The results show that monohull type U is better than others in easiest to bring ocean waste closer to the conveyor and smallest resistance force. Then symmetric trimaran is faster than others in making ocean waste flow to the conveyor.

Abstract

The ship resistance is influential to choose the ship's main engine, especially tankers that have large block coefficients. In general, ship resistance was obtained by modeling the vessel on a certain scale and then testing on the experimental tank. However, this test requires high funding, because testing requires special places such as towing tanks that have expensive operating costs. This research is intended to get ship prisoner with computerized method for tanker ship. Then the result is validated by Holtrop mathematical approximation method. The result of computerized method for speed 11.4 knots got the value of ship resistance is 86.2 KN. While the method of mathematical approach generated ship resistance is 74.38 KN. So the ship's resistance used to determine the tanker machine is 86.2 KN. Keywords: Ship resistance, tanker, computerized

Abstract

Greenhouse gas (GHG) emissions are the most influential issue in the transportation sector in recent years due to their impact on the environment. Thus, the design of transportation power plants is necessary to ensure the lowest GHG emissions. However, the development of a small vessel power plant is discussed in this study. The small vessel is a marine debris working vessel that has the purpose of collecting marine debris on the water surface with a conveyor. This vessel is designed with a dual-fuel engine fueled by natural gas from CNG and diesel fuel in high load conditions. Furthermore, the power system is designed with a systematical assessment condition based on the operational condition. Moreover, an experiment was conducted to study the performance and emissions of the engine. The hybrid system is designed with several operational conditions, such as sailing, collecting, and maneuvering. Most of the operations can be used in the hybrid dual-fuel system with nearly similar engine torque to diesel mode. The dual-fuel hybrid system has a significantly low engine fuel consumption with low CO2 emissions. However, relatively high NO2 and CO emissions are still considerable.

Abstract

The Mayangan Beach Fisheries Port (BFP) in Probolinggo City is a fishing port that was established using a combination of funds from the APBN, APBD of East Java province and APBD of Probolinggo city. Equipped with basic and functional facilities to support various fishing activities, fishing vessels generally use a mechanical propulsion system driven by a diesel engine. The results of the government's decision to increase fuel prices by 8,000 rupiah per liter, were then supported by a survey which showed that fishermen needed as much as 110 liters of fuel for a journey of approximately one hour for one trip, with these conditions making fishermen, especially in the Mayangan district, Probolinggo very objection by increasing the price of fuel that will be used to go to sea, so that with the problems complained of by fishermen on the Mayangan coast, Probolinggo about rising fuel prices, this refers to researchers planning a hybrid propulsion system to reduce consumption of the use of fuel that will be used for purse seine fishing boats. The results showed that the main engine specifications for the Mitsubishi ship were 6D24-Mpt (A) with 228 Kw power, then the Yanmar Ytg 15 Tlv generator, while the electric motor specifications that would be used were Weg Tru Metric 132 Kw / 175 HP, as well as batteries for storing battery energy which had specifications J185-Agm Vrla Agm / Non-Spillable. The difference in fuel consumption in the conventional system and the hybrid system looks quite significant. Using a hybrid propulsion system can produce fuel savings of up to 30% when compared to using a conventional engine.

Abstract

The continuous flow of marine debris in the sea has been a problem until now. Previous research on garbage collection vessels was conducted in calm water conditions, without waves and waves due to wind. This is different from the real conditions in the sea which are choppy and bumpy. In addition, research on the effect of wave length and amplitude on marine debris collection on garbage collection vessels does not yet exist. This study aims to determine the effect of wave length and amplitude on velocity contours, flow patterns, and ship resistance. The ship uses a circular hollow wing conveyor. Modelling using Rhinocheros software, then numerical simulation using Computational Fluid Dynamic (CFD). Verification of the simulation process uses grid independent by varying the mesh size, then validation of the results is done by comparing with previous experimental research. The results show that the best velocity contour in front of the conveyor is at a ship speed of 1.028 m/s (2 knots) using an amplitude of 0.5 T and a wavelength of 0.5 L. The velocity value in front of the conveyor is 1.551 m/s. This affects the speed of collecting marine debris. This affects the speed of collecting marine debris. The model that has a laminar flow pattern at the bow and at the stern is a speed of 1 knot at an amplitude variation of 0.1 T and a wavelength of 0.1 L. This is the best because it is easy to collect garbage. The smallest drag is the speed of 0.514 m/s (1 knot) at amplitude variation of 0.1 T and wavelength of 0.1 L. At this condition, the fuel consumption is the least. Thus, the greater the wavelength and amplitude of the waves the greater the drag and the smaller the speed.

Abstract

The coastal region is characterized by dynamic changes in its coastline, which can be attributed to various factors. However, the main causes of change along the Gresik coast have yet to be thoroughly studied. Therefore, this research aims to examine the patterns of coastline change along the Gresik coast around the Madura Strait and the influence of wind-generated waves on them. Specifically, the study focuses on four coastal zones: Ujung Pangkah, Sidayu, Bungah, and Manyar districts. The research utilizes satellite imagery and geographic information systems (GIS) as well as methods for calculating ocean waves to analyze the coastline change patterns. The study also examines the impact of ocean wave energy on coastal abrasion and accretion. The findings revealed that the accretion rate in the study area was higher than the erosion rate. The accretion in the coastal area of Gresik is attributed to the flow of the Bengawan Solo River, which carries sediment from upstream. The accretion and abrasion areas for the entire period from 2002 to 2019 were 1063.16 ha and 425.23 ha, respectively. The study also found that the mangrove areas exhibit a higher rate of accretion than abrasion, indicating their potential as a reliable indicator of the effects of sea level rise resulting from global warming.This study revealed that the northern part of Ujung Pangkah District and Bungah District experienced the highest abrasion patterns, whereas no abrasion was observed in Sidayu District. Between 2002 and 2019, the abrasion areas in Ujung Pangkah and Bungah districts totaled 243.96 ha and 178.29 ha, respectively. Wind-generated waves were likely the primary cause of the abrasion in these areas, though other factors may also have contributed to coastline changes. It is essential to consider these factors for effective coastal management in the region.

Abstract

A ducted propeller is a modification of a propeller by adding a duct or nozzle. The purpose of using a ducted propeller is to increase thrust, increase propeller efficiency, and encourage better ship movement. This is suitable for Offshore Supply Vessel (OSV) vessels operating on offshore platforms to support oil drilling activities. In designing a kort nozzle, one of the most important components is the tip clearance, the distance between the edge of the propeller and the inner nozzle. The diameter of the kort nozzle can affect the thrust efficiency of the propeller. Due to the blade momentum theory for ducted propellers, the volume of water passing through the propeller should be as large as possible, with the smallest possible flow velocity. In this study, numerical simulations using the Computational Fluid Dynamics (CFD) method were carried out to determine the effect of tip clearance on thrust and torque on a ducted propeller with a MARIN foil 19A nozzle type and tip clearance of 10 mm, 20 mm, and 30 mm. From all models, the highest thrust and torque values were obtained from the nozzle 19A tip clearance 10 mm model with thrust 367,413 kN and torque 315,338 kNm. The relationship between tip clearance and thrust is inversely proportional; the greater the tip clearance, the smaller the value of thrust, and the same is true with torque.

Abstract

The freezer machine is one of the tools on board and serves to maintain the temperature of food ingredients to keep it in good condition and fresh. Given the importance of this, the cooling machine is a tool that functions to make durable foodstuffs by naturally maintaining the temperature. Standard freezer machines produce temperatures only up to -15oC. Modification of the freezer machine needs to be done so that the temperature reaches a lower minus again by changing the capillary pipe from standard to double helical. The purpose of this study is to analyze the effect of double helical capillary pipes on the working performance of a 100-liter capacity freezer cooling machine using R600A refrigerant. In this study the frezzer machine was modified by replacing a single capillary pipe into a double helical. The method used is to conduct experiments to take data to determine the temperature produced and calculate the Coefficient of Performance (COP)  before and after modification. The results of this study are the lowest temperature in the double helical capillary pipe variation during the three-hour test obtained a temperature in the range of -20.2oC while the standard capillary pipe obtained a temperature in the range of -14.9oC. The average COP for standard capillary pipes is greater at 2.773 compared to the COP of double helical capillary pipes which is 2.421. At double helical temperature values are cooler than standard capillary pipes. However, the disadvantage is that the COP of the double-helical capillary pipe is lower than the COP of the standard capillary pipe.

Abstract

Seiring dengan perkembangan teknologi dalam proses pembangunan kapal kayu, galangan kapal kayu tradisional selalu tertinggal dengan galangan kapal kayu modern. Pengrajin kapal kayu tradisional mengalami kesulitan memperoleh bahan baku yang baik dalam membangun sebuah kapal karena kebijakan pemerintah menekan kegiatan pembalakan liar. Kebanyakan kapal yang dibuat menggunakan bahan baku yang tidak memenuhi persyaratan Biro Klasifikasi, sehingga performa kapal tidak sesuai standar. Selain itu, para pengarajin tersebut biasanya memperoleh keahliannya secara turun temurun. Adanya kendala yang dihadapi tersebut, secara segi ekonomi galangan kapal rakyat ini tidak masuk kedalam kategori usaha yang sehat walaupun produktif. Padahal mereka memiliki peran besar dalam memenuhi kebutuhan kapal penangkap ikan dalam berbagai ukuran dan tidak menutut kemungkinan juga ternyata masih bayak pemuda lokal yang berpotensial. Oleh karena itu, galangan kapal kayu tradisional khususnya didaerah Paciran Lamongan perlu adanya sebuah program untuk menangani masalah ini. Salah satunya dengan cara memberikan pelatihan menganai proses pembangunan kapal kayu yang lebih ekonomis dan efisien ditinjau dari bahan baku yang digunakan. Program ini diharapkan akan mampu meningkatkan kemampuan sumber daya manusia (SDM) para pengrajin kapal kayu di wilayah tersebut menjadi lebih berkompeten dan professional, sehingga dapat memanfaatankan peluang material alternatif yang akan membantu usaha mereka lebih bernilai ekonomi tinggi.
