Abstract

Maritime is a vital sector that highly depends on ship propulsion systems to support mobility and maritime security. One of the developing propulsion technologies is the waterjet thruster, which provides advantages in maneuverability, efficiency, and resistance to cavitation for high-speed vessels. This study aims to experimentally investigate the performance of a twin waterjet thruster made of stainless steel 304. The prototype was designed using SolidWorks software with a configuration of 12-blade inlet, 3-blade impeller, and 12-blade outlet, and tested using a 22 HP combustion engine at 2,300 rpm in a water test tank. The results showed thrust values of 23 kg, 24 kg, and 25 kg with an average of 24 kg or 235.44 N. The variations were influenced by water flow conditions, pump pressure, and engine stability. Overall, the twin waterjet thruster made of stainless steel 304 proved to be effective, consistent, and has the potential for further development with higher engine speeds or different drive types for real ship applications.

Abstract

Indonesia, as an archipelagic country, requiresefficient sea transportation systems, particularly forsmall to medium-sized fishing vessels. One innovationdeveloped to support this need is the twin propulsionsystem driven by a single engine. This study aims toevaluate the performance of a 2-blade propeller in atwin screw configuration, focusing on thrust, speed,efficiency, and vessel stability. The experimentalmethod was conducted through direct testing in awater tank using a 22 HP four-stroke gasoline engine,which transmitted power to two propeller shafts via achain and sprocket mechanism. The results show thatthrust increases with engine speed. At 2300 RPM, theaverage thrust obtained was 39.24 N, while at 4600RPM, it significantly increased to 78.48 N. Thesefindings confirm a linear relationship between RPMincrement and thrust production. Overall, the twinpropulsion system with a 2-blade propellerdemonstrated good performance, stability, andresponsiveness to engine speed variations. This studyis expected to serve as a reference for the developmentof propulsion systems for fishing boats and smallvessels that are more efficient and well-suited to theconditions of Indonesia’s archipelagic waters,particularly in the Bangka Belitung region.

Abstract

A recent development in the manufacturing sector is 3D printing technology. through the direct conversion of 3D computer-aided design (CAD) data into a tangible prototype using the concepts of additive manufacturing. The way that 3D printing technology constructs a prototype is layer by layer. Fibrous materials can be printed using fused deposition modeling (FDM) technology, which produces products with precise geometric properties. Using the Taguchi Method L27(33), three variants of the fixed A transparent ABS There were Three process parameters employed in the study: Nozzle Temperature, Build Plate Temperature, and Print Speed. Filament with a diameter of 1.75 was also used. This study makes use of an FDM Ender 3 Max 3D printer, which has dimensions of x300mm x300mm x350mm. This study's objective is to. The purpose of this study is to measure the surface roughness.test results. The study's experimental findings indicated that, for specimen 2 trials, the ideal roughness value was an average of 14, with the follow parameters, which include 50% print speed, 85°C for the build plate and 250°C for the nozzle temperature.

Abstract

Additive manufacturing, particularly 3D printing, has emerged as a transformative technology in digital fabrication, enabling the rapid, accurate, and cost-effective production of complex components. Among the various 3D printing methods, Fused Deposition Modeling (FDM) is one of the most prevalent techniques, employing thermoplastic filaments as its primary material source. This research aims to determine the optimal process parameters to achieve the highest tensile strength in components fabricated using food-grade Polylactic Acid (PLA) filament. To accomplish this, the Taguchi method was implemented as a robust design tool to optimize the manufacturing process, improve material performance, and reduce both cost and resource consumption. The experimental design followed the L27 Orthogonal Array, and the analysis was conducted using the Signal-to-Noise Ratio (SNR) to identify the most significant parameter combinations affecting tensile strength outcomes. The investigated process parameters included extruder temperature, build plate temperature, layer thickness, infill pattern, and deposition speed. Based on the results, the optimal conditions for maximizing tensile strength were identified as follows: extruder temperature of 190 °C, build plate temperature of 60 °C, layer thickness of 0.2 mm, triangle infill pattern, and deposition speed of 60 mm/s. Additionally, the parameters with the greatest influence on tensile strength, ranked from most to least impactful, were: build plate temperature, layer thickness, infill pattern, deposition speed, and extruder temperature.
