This research endeavors to explore a novel alternative fuel source by combining waste used cooking oil and corn oil to create a biodiesel blend. The study addresses two main objectives: first, to investigate the properties of used cooking oil biodiesel with the addition of methanol and NaOH catalysts, and second, to assess engine performance using the biodiesel blend. The experimental approach employs transesterification, varying the catalyst quantity during biodiesel production. Preceding diesel engine testing, properties such as viscosity are assessed, revealing improved values meeting Indonesian National Standards post-catalyst addition, albeit with a decrease in calorific value. Engine performance is then evaluated, demonstrating that as the catalyst content increases, torque and thermal efficiency decrease, while specific fuel consumption (SFC) rises. Notably, the study concludes that a higher catalyst ratio aligns fuel properties closer to government-set standards. The most favorable engine performance is observed in the B50 sample with a catalyst variation of 1000 ml of methanol and 25 g of NaOH, showcasing superior torque, thermal efficiency, and opacity values compared to higher catalyst variations. This research underscores the importance of catalyst optimization in achieving an environmentally friendly biodiesel blend with enhanced engine performance.

Ships generally use diesel engines as propulsion to produce energy from the combustion process. The fuel used on ships uses diesel oil, but its use can result in marine environmental pollution. Marine environmental pollution is currently a national issue that must be addressed immediately, where the International Maritime Organization (IMO) in MARPOL Annex VI TIER III limits the content of exhaust emissions. This research is to analyze the effect on engine performance and emissions, especially NOx produced by diesel engines, then compare NOx emission data with IMO TIER III standards. This research uses an experimental method by mixing two fuels with the composition B0 (pure plastic waste), B1 (80% - 20%), B2 (70% - 30%). After conducting research the effective result is B1 fuel. Because trendline graphs are quite optimal for use on diesel engines. The power produced by B1 is 1.36 KW to 2.12 KW. SFC B1 produces 431.35 g/kWh to 352.61 g/kWh. For efficiency, B1 produces 19.3% to 23.6%. For torque, bmep, and fc produce values that are directly proportional to engine speed. The results of the NOx emissions test were obtained for each type of fuel composition, B0 was 174 gr/kWh – 185gr/kWh, B1 was 182gr/kWh – 218gr/kWh and B2 was 198gr/kWh – 224gr/kWh. This meets the MARPOL Annex TIER III standards.

This paper proposes an improved Maximum Power Point Tracking (MPPT) algorithm for photovoltaic (PV) systems under partial shading conditions. The proposed method enhances the widely used Incremental Conductance (IC) algorithm by incorporating an incremental fuzzy control technique. The conventional IC algorithm suffers from limitations in adapting to rapidly changing irradiation conditions due to its fixed step size. The proposed Inc-Fuzzy algorithm dynamically adjusts the step size based on the change in power and voltage, enabling it to better track the Global Maximum Power Point (GMPP) under partial shading. Simulation results demonstrate that the Inc-Fuzzy algorithm achieves an average accuracy of 98.29% under constant irradiation and outperforms the conventional IC algorithm by 1.69% in terms of captured power during sudden irradiation changes. This improvement highlights the effectiveness of the Inc-Fuzzy approach in enhancing the performance of MPPT for PV systems under challenging operating conditions.

Estimate the ship’s weight steel is very important before pre-design. This is useful to ensure that the ship's weight does not exceed the basic design requested by the owner. 3D modeling is made in order to shorten the work time and produce a more precise calculation of the weight of the ship compared using mathematical calculations. The study compares the ship weight by using a mathematical method and using the 3D modelling method using autodesk inventor software. The result of the estimation of the weight of the ship’s steel cargo hold construction using 3D modelling method for the block system. It was found that the calculation of the weight of steel using the autodesk inventor method has a fairly good difference with the mathematical method. Calculation with 3D modelling autodesk inventor has a total steel weight of 255,077 tons and 259,868 tons for the mathematical method. The difference in autodesk inventor result is 4,791 tons or 1,84% less than the ship’s weight steel mathematical method.

Symmetric airfoils like NACA 0015 have limitations in generating lift compared to asymmetric airfoils. Therefore, additional devices are needed to overcome this limitation. This research analyzes the use of a lift enhancement device called a plain flap, which is installed on the trailing edge of the NACA 0015 airfoil using the CFD method. Simulations were conducted at a Reynolds number of using the k-epsilon turbulent model. Three variations of geometry models were simulated: the NACA 0015 airfoil without a flap, the NACA 0015 airfoil with a plain flap at a deflection angle of 15°, and the NACA 0015 airfoil with a plain flap at a deflection angle of 30°. The simulation results show that the use of a flap can increase the maximum lift coefficient (Cl) of the airfoil. Initially, the maximum lift coefficient was 1.15 at an angle of attack (AoA) of 15°. With a plain flap deflection angle of 15°, the maximum lift coefficient increased to 1.5 at an AoA of 13°. With a plain flap deflection angle of 30°, the maximum lift coefficient further increased to 1.71 at an AoA of 10°. However, the use of a plain flap also leads to a significant increase in drag. On average, the drag coefficient (Cd) increased by 65% with a plain flap deflection angle of 15° and by 178% with a plain flap deflection angle of 30°.

A ship tank’s ventilation pipes protector, called PS60, is produced by an investment casting process using CF8M material. Shorter time production for PS60 products, occurred due to the rise of PS60 demand, resulting non class casting product quality. Reported that 15% of PS60 defective products were shown from each production group. Porosity defects are the most common defects found. Recalculating riser’s, runners’s, and ingates’s dimensions, then remodeling designs a mold gating system done in order to reduce the percentage of defective products and increase production capacity. Remodeling gating system and casting simulation done by ProCast 2018 software using New Advanced Porocity Module (NAPM). The casting simulation output was porosity defects location and percentage, which were further analyzed. The product produced using a mold Gating system with a new layout, had 314.73 cm3 of empty part in the mold cavity which was identified as a porosity defect which was 4.58% of the total volume of the cast product. The total value of the porosity after remodeling decreases by 2.39% from the existing product. 93.3% of the cavity inside the product is categorized as macroscopic porosity defects that are centralized in the riser and pouring basin areas, where in the casting product finishing process, these areas will be removed. Modification of the Gating System in PS60 mold escalates twice of PS60 capacity production than the origin.

The escalating utilization of FRP materials ultimately gives rise to issues related to waste production. Waste disposal typically involves incineration, as practiced at UD Wahyu Asih Fiberglass. The combustion process yields thick black smoke and a pungent odor. Incineration does not annihilate fiberglass material but generates combustion byproducts, such as solid ash. This study aims to elucidate the material type, chemical element content, and associated properties inherent in FRP shipbuilding materials at UD Wahyu Asih Fiberglass Shipyard. The methodology commences with the identification of materials utilized in FRP ship manufacture through field observations at the shipyard. Another objective of this study is to quantify the ash content and ascertain the total particulate matter during the incineration process of FRP shipbuilding material waste via laboratory tests. The total particulate data obtained will be compared with applicable emission quality standards.

The Remotely Operated Underwater Vehicle (ROV) has several inspection functions. One of them is the inspection function for hull damage. The damage that often occurs in the hull is corrosion. The corrosion can cause a decrease in the strength of the hull plate, reduce the speed of the ship, and decrease the quality of the safety level of ships and passengers. This study aims to classify the level of corrosion intensity on ship hulls by implementing a Convolutional Neural Network (CNN). Identification is carried out on images taken by underwater cameras via a Remotely Operated Vehicle (ROV). The intensity of the area affected by corrosion is identified so that the level of corrosion intensity can be classified and it can be considered that the ship needs maintenance to prevent even greater losses due to corrosion. The dataset used is 240 image data divided into 3 classification categories: low, medium, and high corrosion intensity. The accuracy of the real-time testing of the CNN method on the dataset plate when conditions outside the water reached 91.1% and on the dataset plate when conditions underwater reached 86.6%.
