Abstract

Study This aim For designing construction addition and analysis strength elongated floating dock 6000 TLC as access repair boat use Finite Element Method (FEM). Problems found is ratio long a floating dock that doesn't sufficient when repair carried out on ships with 60 to 80 meters long, so worker difficulty working in parts tall bow and stern. For overcome problem this, design construction addition done with three variation long, that is 8 meters, 10 meters and 12 meters. Analysis results show that construction addition increase accessibility worker For repair ship on the part bow and stern. From third testing strength elongated show that construction addition capable withhold burden addition without exceed voltage permits set by American Bureau of Shipping (ABS). Voltage flexible maximum is 42.35 MPa for 8 meters variation, 59,741 MPa for 10 meters variation, and 71,486 MPa for 12 meters variation, meanwhile voltage shift maximum is 20,709 MPa for 8 meters variation, 29,038 MPa for variation of 10 meters, and 34.93 MPa for 12 meters variation. All variation own factor safety more big of 1, so structure stated safe For used. Keywords : ABS, Design, FEM, construction, stress

Abstract

The demand for durable custom vehicle components requires enhancing the mechanical characteristics of Stereolithography (SLA) materials, which are generally brittle—a gap that must be addressed through post-processing optimization. This study aims to identify the optimal post-processing parameter combinations to maximize the hardness of SLA resin using the Grey Relational Analysis (GRA) method. The experimental design followed a Taguchi L9 orthogonal array, testing four factors Washing Time, Curing Time, Annealing Time, and Annealing Temperature at three levels each, with Shore D hardness as the quality response. The results demonstrated a significant increase in hardness from a baseline of 79.2 Shore D to 82.5 Shore D under optimal conditions. The GRA identified the combination of 15 min Washing Time, 25 min Curing Time, 30 min Annealing Time, and 80°C Annealing Temperature as the optimum setting, resulting in a 16.4% improvement in the Grey Relational Grade (GRG) compared to the experimental mean. ANOVA results confirmed that Washing Time (50.79% contribution, P=0.028) and Annealing Time (41.49% contribution, P=0.034) were the most significant factors (P < 0.05) influencing hardness variation. Conversely, Curing Time was found to be insignificant (P=0.189), suggesting that 15 minutes is sufficient, while residual monomer removal and thermal stress relief during annealing are more critical. Overall, this study concludes that enhancing SLA material hardness depends heavily on thorough cleaning and controlled heat treatment.

Abstract

Bangsring Beach is one of the leading tourist destinations in Banyuwangi Regency. Bangsring Beach which focuses on underwater tourism (Bangsring Underwater) is a coral reef-based tourism that can only be accessed by diving and snorkeling. But only in that way to enjoy Bangsring Underwater tourism, the construction of a 12 m catamaran with a bottom glass is carried out so that tourists who cannot dive and snorkel can enjoy the beauty of Bangsring Underwater. To ensure the comfort and safety of passengers, a simulation analysis of the movement of the existing 12-merter catamaran is carried out. This simulation was carried out with the general design of a catamaran modeled 1:1 with a LOA of 12 m, B 5.6 m, H 1.85 m, and Vs 10 knots. On the 1:1 ship, an exsisting process is carried out at each ship station to get a line plan for the Garufa Ngelayang ship then 3D modeling is carried out based on the reference from the line plan drawing. Ship motion simulations are carried out to determine the ship's response when hit by waves from various directions which are presented in the RAO (Response Amplitude Operator) graph using the CFD method which is based on a 3D model. Simulations were carried out with a wave height of 1.25 m in Bangsring waters with a fully loaded ship with a wave direction of 0o following sea; Stern Quarter 45o, 315o; Beam Sea 90o, 315o; Bow Quarter 135o, 225o; and Head Sea 180o. With a comfortable ship condition with 2.052 s of ship shaky period.

Abstract

Robot technology has penetrated various sectors, including households. One example of robotic innovation for household needs is the vacuum cleaner robot. This research aims to optimize sensor usage while implementing a differential drive system using a tricycle platform consisting of one caster wheel and two differential wheels. Testing was conducted in a space measuring 150 cm × 130 cm with obstacles such as a four-legged chair, cracker crumbs, sunflower seed husks, small pieces of paper, and a handful of dust (flour). The results showed that the robot could navigate quite smoothly and optimally even only using an HC-SR04 ultrasonic sensor. However, more complex challenges within households, such as getting stuck in carpet rolls, handling various types of trash or debris, or moving in narrow spaces, are still aspects that this robot has not fully addressed
