Abstract

Margin plate is a part of bottom construction that joint the floor and frame construction of the ship, so the inner bottom plate will be installed cut off on the margin plate. Lately the bottom construction of the ship tends not to use the margin plate. The ship is currently built with an inner bottom plate continuously from the left side to the right side of the ship.This study aims to determine the transversal and longitudinal strength ratio of ships with and without margin plate. The analysis was carried out by using Finite Element Method so-called ANSYSTM. The result shows if the loadvariatied 0.2 x maximum load on the calculation of the transverse strength of the ship, the stress value on the ship model with a margin plate was 9.6242 (N/mm2) and on the ship model without margin plate was 8.4739 (N/mm2) under conditions 100%. The results of the comparison due to bottom load averaged 15.82%. The difference in stress due to the effect of deck loads was an average of 13.49% while the effect of side loads was on average 8.74%. The longitudinal strength of the ship was also a varied of every increase of 0.2 x maximum moment with a review point of meeting between bottom plate and bilga plate for the ship model without margin plates using the Multi Point Constraint (MPC) method looking for results in sagging conditions of 12,443 (N / mm2) and the hogging condition was -11.045 (N / mm2) at 100% x maximum moment load conditions. So that the ship model with a margin plate sagging condition was 23,189 (N / mm2) and hagging condition was -20,585 (N / mm2). The results showed the stress that occurred in the ship model without using margin plate was better to withstand the transverse and longitudinal strength of the ship compared to the ship model with the margin plate.

Abstract

With the use of the bracing model that was built during the building of the ladder-pulley foundation, this research intends to analyze the strength of the ladder-pulley foundation on the Kapal Isap Produksi (KIP). Finite element analysis (FEA) and modeling with the Ansys software were used in the investigation. The 58 m length of the actual ladder is considered when creating the model. Then, create each model of a diagonal brace and an x-bracing specifically for the pulley foundation. After that, a special diagonal brace and an x-bracing model were developed, respectively, for the pulley foundation's building. The load acting on the ladder for the two versions is the same: 1.42 x 105 N for the pipe and mud, 0.57 x 105 N for the cutter, and 0.67 x 108 Nmm for the cutter torque. According to the analysis's findings, the diagonal brace model's strut component experiences the highest level of stress, measuring 57.32 N/mm2, whereas the x-bracing model's greatest stress value is 25.44 N/mm2. These findings suggest that, to reduce structural failure in the ladder pulley area, it is preferable to use x-bracing construction for the brace design put there. This is because it has a lower minimum stress value than the diagonal brace model. Keywords: Bracing, Ladder, KIP, FEA.

Abstract

The more frequent mining activities are carried out, the deeper the tin on the seabed, therefore many ship owners want to increase the length of the ladder on production suction vessels. The owner of the KIP Timah 8 suction boat will increase the length of the ladder to 70 meters, which previously was only 58 meters. The paper research are the response of the ladder structure before and after being extended, the limit strength of the ladder structure in the pulley area, then the ultimate strength of the longitudinal ladder structure due to the vertical bending moment. Lenght of the ladder construction subsequently increases commencing 58 m, 62 m, 66 m, to 70 m with each increase in length varying the slope angle of the ladder starting from 0o, 30o, 45o, to 60o. This paper uses a numerical method with the help of ansys software. The structure being reviewed is only in the ship ladder area. The response of the ladder structure before and after being extended, the maximum stress value occurs in the strut construction which is 49 meters from the ladder shaft, which is 56.88 N/mm2 and the maximum shift is 14.28 mm when the ladder length is 70 meters and still meets the allowable stress. Investigation of the limit strength using the Nonlinear Finite Element Analysis (NLFEA) method. Based on the results the analysis of the strength longitudinal ladder structure in the hogging and sagging conditions 42 meters from the ladder shaft, the maximum deflection in the column is 131.73 mm from the initial position before being loaded. While at an angle of 60 degrees it will collapse when deflection 66.17 mm. The results of the analysis showed that the load acting on the ladder the pipe load, cutter load and cutter torque the resulting stress still meets the stress that the longer ladder is directly proportional to the resulting stress and deflection value and the greater the slope of the ladder, the smaller stress and deflection.

Abstract

 Riset ini bertujuan untuk menganalisis kegagalan struktur ladder pada Kapal Isap Produksi (KIP) Timah 19 yang telah mengalami patah ladder mengakibatkan beberapa komponen dan peralatan ladder seperti cutter hilang di dasar laut, salah satu penyebabnya yaitu pengaruh model bracing yang dipasang pada konstruksi pondasi katrol ladder sehingga menimbulkan biaya yang sangat besar untuk perbaikan ladder yang patah. Riset dilaksanakan menggunakan finite element analysis dengan pemodelan menggunakan bantuan software Ansys. Model ladder dibuat sesuai aktual dengan panjang ladder 59 meter. Kemudian dibuat masing-masing model diagonal bracing dan x-bracing khusus pada konstruksi pondasi katrol. Beban yang bekerja pada ladder untuk dua model sama yaitu berat pipa dan lumpur sebesar 1,42 x 105 N, berat cutter sebesar 0,57 x 105 N dan torsi cutter sebesar 0,67 x 108 N.mm. Hasil analisis menunjukkan bahwa tegangan maksimum terjadi pada komponen strut tepat di bawah pondasi katrol untuk model diagonal bracing sebesar 57,32 N/mm2 dibandingkan dengan model x-bracing sebesar 36,88 N/mm2. Hasil ini menunjukkan bahwa konstruksi brace yang dipasang pada area katrol ladder sangat mempengaruhi nilai tegangan sehingga untuk meminimalisir kegagalan struktur ladder khususnya pada area katrol sebaiknya menggunakan konstruksi x-bracing karena memiliki nilai tegangan minimum dibandingkan konstruksi diagonal bracing yang terpasang saat ini pada KIP.

Abstract

The material-cutting process is one of the critical stages in the manufacturing industry that can affect the quality and success of the final product. The TruLaser 5040 machine is a material-cutting machine that is often used in industry to cut various types of materials with high precision. However, even though this machine has been well designed, failures sometimes occur in the cutting process which results in defects in the material being processed. This study aims to analyze the failures that occur in the material-cutting process using the TruLaser 5040 machine. This research uses a qualitative approach with a descriptive research type and the research informants are machine operators. This study has several stages which include data collection through direct observation, interviews, and descriptive analysis of the collected data. The results of the research conducted found several factors causing failure in the material cutting process including human error, machine error, material error, cutting size error, and cutting defects. Things that can be done to avoid material cutting failures are ensuring the condition of the machine and its main components such as nozzles, protective glass, and so on are in good condition. Material conditions must also be adjusted to the cutting parameters on the machine which include cutting distance, tip diameter, current, gas pressure, and cutting speed so that dross and defects do not occur in the cutting material.

Abstract

Fishermen operating in the waters of Southeast Sulawesi typically use fishing vessels powered by diesel engines. Additionally, the onboard basic electrical needs are met using batteries that must be manually charged, leading to increased time, costs, and workload for the fishermen. Given the vast potential of the region, an in-depth analysis is needed to explore the integration of renewable energy with diesel engines to better support local fishermen. This study aims to develop a design for a 10 GT multifunctional fishing vessel that incorporates a hybrid power system, utilizing solar energy as an alternative electrical energy source in combination with a diesel engine. The creation of this multifunctional vessel design will enable year-round operation by adapting to seasonal changes in Indonesia while maintaining high-quality catch production. The research findings indicate that a 10 GT fishing vessel with a length of 15 meters, width of 5 meters, and a draft of 0.75 meters can be equipped with a 40 PK diesel engine and a 60-volt electric outboard motor. The Compton method yielded a resistance of 9.8 kN and a power requirement of 50.5 kW. The Fung method calculated a resistance of 6.5 kN and a power of 33.3 kW, while the Holtrop method produced a resistance of 5.3 kN and a power of 27.4 kW. The proposed solar energy system for the vessel includes six solar panels, each with a capacity of 250 WP, providing power for both the ship's engine and onboard electrical equipment.
