Abstract

In late December 2021, the ship KM Tarex 2, owned by PT. Pelayaran Mandala Sejahtera Abadi, underwent its annual docking at PT. Tambangan Permai Raya. During this time, the ship was found to be in a state of disrepair, including its accommodation rooms. The ship's current condition, feedback from stakeholders, and financial considerations served as the catalyst for a comprehensive interior redesign, with a primary focus on enhancing comfort, safety, and economy. The interior redesign of the accommodation spaces on the ship KM Tarex 2 involved the exploration of two alternative design concepts. These concepts centered around the Owner's Room, Crew's Room, Messroom and Life Jacket Storage. Alternative Design 1 adopted a Contemporary Concept, while Alternative Design 2 embraced a Modern Minimalist concept. The selection process for these designs involved soliciting feedback from a panel of 18 individuals, consisting of 12 representatives from PT. Pelayaran Mandala Sejahtera Abadi, 3 individuals from PT. Tambangan Permai Raya, and 3 crew members of the ship KM Tarex 2. Ultimately, Alternative Design 1 garnered an average approval rating of 67% across all rooms, surpassing Alternative Design 2 in preference. The selected design alternatives were evaluated for compliance with regulatory standards, achieving a 100% compliance rate for each room and an average comfort rating of 40%. Additionally, the chosen materials, as determined through a Google Form questionnaire, included ALUMETAL brand ACP Materials for room lining and ceiling, along with Henan Fortovan brand LVT for ship deck covering. These materials received an average approval rating of 61%. Economically, the analysis of material costs demonstrated that the project could be undertaken without exceeding the ship's annual income, ensuring financial feasibility.

Abstract

The water wheel is an important tool used in cultivating vaname shrimp, which functions as  depositing oxygen in cultivation ponds. HDPE is a polymer material used as a waterwheel float. In outdoor working environment of the waterwheel float in the cultivation pond, which exposed to direct sunlight, resulting in an increase in temperature. The influence of heat from the sun certainly affects to the degradation process of the waterwheel float. In this study, HDPE material was given a variety of heat treatments. The variation of heat given was adjusted to the results of observing field conditions for 1 week where the water wheel was used in the aquaculture pond. The variations of heat treatment given were without treatment, lowest, average, highest temperature heat treatment, and cycles. This research aims to determine the effect of heat on reducing tensile strength, the condition of the functional groups contained, and the service life of the material. The result was a 9% reduction in tensile strength in the samples that were given the highest thermal treatment. Degradation due to thermal effects is proven by the decrease in wave peak intensity for each functional group contained in the HDPE material. Calculation of the estimated service life of the HDPE float must be replaced as fast within 5 months. Kincir air merupakan alat yang penting yang digunakan dalam melakukan budidaya udang vaname, yang berfungsi sebagai alat deposit oksigen pada kolam budidaya. HDPE adalah salah satu material polimer yang digunakan sebagai pelampung kincir air. Lingkungan kerja pelampung kincir air pada kolam budidaya yang terletak di luar ruangan, yang tentunya terpapar matahari langsung, mengakibatkan adanya peningkatan temperatur. Pengaruh panas dari matahari tentunya berpengaruh pada proses degradasi pelampung kincir air. Dalam penelitian ini, material HDPE diberikan variasi perlakuan panas.

Abstract

Fenders are structures installed on the edges of ships to protect the ship's hull from impact with the dock. The main function of fenders is to absorb the collision energy generated by the ship's impact during berthing at a dock. The load applied to fenders on each ship results in stress distribution in the surrounding hull area, which can lead to various issues such as damage, cracks, deformations, and others. Additionally, the presence of fenders with different shapes can affect the stress distribution values in the surrounding hull area. Hence, a local stress analysis using finite element method software is necessary. The analysis focuses on static loads originating from the ship itself when docked at a port. However, only the fender section is analyzed, and it is not necessary to consider the entire ship's body. The objective of the analysis is to determine the stress characteristics and maximum stress values in the fender itself. The analysis results reveal that the highest stress value occurs in the half-pipe-shaped fender with a value of 0.22809 MPa. Based on these findings, it can be concluded that the stress values in the fender meet the allowable standards. In conclusion, this analysis provides an understanding of stress and the maximum stress value in ship fenders. This knowledge is crucial to ensure that fenders effectively fulfill their function of protecting the ship from impacts with docks.

Abstract

This study focuses on analyzing the structural strength of car deck construction in roll-on/roll-off (ro-ro) passenger ships. Ro-ro ships are designed to transport both vehicles and passengers, in which vehicles can drive in and out under their own power. While these ships are operational, there is a potential for improvement in their construction strength, particularly in the car deck area. The car deck is a critical structural component as it bears both vehicle loads and supports the upper decks. This research analyzes the car deck's structural integrity, which was initially designed for trucks and sport utility vehicles (SUV), under various conditions including calm water, sagging, and hogging scenarios. Using both finite element method (FEM) analysis through ANSYS software and manual calculations via Excel, the study evaluates maximum stress points and deflection. The 3D modeling was completed using Fusion 360, while 2D drawings were created in AutoCAD. Results revealed that the highest stress occurs during hogging conditions with truck loads, showing 188.23 MPa stress and 0.077128 m deflection. With a safety factor of 1.3281, these values comply with Indonesian Classification Bureau (BKI) standards, which require stress below 250 MPa and a safety factor above 1.

Abstract

A slow sand filter is a natural water filtration system that uses fine quartz-rich sand as a filter medium. The filtration process runs by gravity at a slow and even speed over the entire surface of the sand, involving physical, biochemical and biological processes simultaneously. To achieve the desired water quality, the filtration system was designed using 8" PVC pipes. The main aim of this design is to mature the filter sand media and form an effective filter skin layer, so that biochemical and biological processes can take place optimally. In this design, silica sand and gravel media are used for physical and chemical processes, while ultraviolet lamps are used to eliminate E.Coli bacteria in biological processes. The design results show that the resulting product meets the standards of PERMENKES No. 16 of 2005. Irradiation using a UV lamp for one hour shows a reduction in E. Coli bacteria by 29/100 ml. This shows that the longer the exposure, the less bacteria contained in river water. This system can operate for 5 hours with the help of a 100 Wp solar panel, 12 volt 18 Ah battery, and 50 watt DC pump, even just with sunlight. The efficiency of solar panels is greatly influenced by the intensity of sunlight, so the higher the intensity of the sun, the higher the efficiency produced.

Abstract

Shielding gas is an important thing to protect the weld metal from impurities during the welding process. Ar, CO2, and mixing gas of Ar-CO2 are often used as a shielding gas in the marine industry. Differences in shielding gases and the current of welding could affect the microstructure and hardness of welding. This research analyzed the microstructure and hardness from the FCAW process of Shipbuilding Steel Plate using mixing gas and shielding gas of 100% CO2 with variations of current 180 and 195 A. The filler metal which has been used was A 5.20 E-71T1. The microstructure for the weld metal with 100% CO2 shielding gas was pearlite, widmanstatten ferrite, grain ferrite, and polygonal ferrite; otherwise for mixing shielding gas of 80% Ar + 20% CO2 and 75%Ar + 25% CO2 was found, the structure of pearlite, grain ferrite, and acicular ferrite. The effect of variations in the shielding gas composition and welding current that produced the highest hardness value was achieved with a shielding gas composition of 80% Ar + 20% CO2 and a current of 195 A, resulting in a hardness of 159.2 HV in the weld area.

Abstract

Aerators play an important role in maintaining shrimp survival in aquaculture ponds. To improve aerator performance, good quality and durability floats are required to support the optimization of aerator loads. Because aerators operate in open areas exposed to sunlight, there is a possibility that aerators will degrade due to exposure to ultraviolet light from the sun. Therefore, this study reviews the impact of ultraviolet light on the decrease in tensile mechanical properties and changes in functional groups in float materials made of HDPE. Tensile test samples were replicated three times in each variation to obtain reliable experimental results, then FTIR testing was performed. The results show that the sample with the highest exposure has the largest decrease in tensile strength, which is about 14%. Based on FTIR analysis, ultraviolet radiation does not reduce functional groups, but reduces the intensity of each functional group. HDPE has an approximate service life of 1664 days.
