Robotic welding has garnered significant attention in the maritime industry for its potential to enhance marine structure quality and optimize production processes. This systematic literature review aims to provide a comprehensive overview of the current state of research in robotic welding for marine applications, encompassing marine structures an...

The shipbuilding sector is currently facing issues due to long manufacturing schedules and delays in ship construction completion. These challenges come from national shipyards' conventional onboard outfitting process for equipment installation, which takes a lengthy time to complete. To address this issue, this study proposes implementing the adva...

Conventional welding techniques for complex structures often rely on human involvement, which can be prone to errors when deviations from the planned process occur. In contrast, robotic welding is highly precise and effective, particularly in the assembly of complex structures such as double-bottom ships. Therefore, this paper presents a comprehens...

Cradle is a lifting tool used to transport ships. The innovation of the cradle design as a deck tool for transporting ships to the dock is a breakthrough to simplify the transportation process. Of course, in the design process, a method is needed to get a design that meets the standard. Numerical simulation is a method that is applied to determine...

System and outfitting in a ship vary with different brands and treatment methods. These conditions can be an issue if the operator has undisclosed damages due to a lack of knowledge about the ship's maintenance records. An electronic planned maintenance system (ePMS) is a system that is currently used to collect the ship maintenance recorded data....

The conversion of floating docks from single pontoon to multi pontoon is a beneficial alternative for shipyards to enhance the performance of the facilities owned. The objective of this research is to analyze technically and economically the conversion of single pontoon floating dock to multi pontoon. The results of calculations used the 2.2 Finite...

Process monitoring of ship production in Indonesia is currently still using conventional methods. Ship production has stages, preparation to the erection. Each of these stages has results that need to monitor and their progress recorded. Therefore, it is necessary to have a system that fasts, practical, and responsive monitoring directly in the wor...

Several studies on the mechanical properties of bamboo slats have been carried out using various types of bamboo species, including Dendro Calamus Asper sp, Gigantochloa Apus sp, Bambusa Arundinacea sp. Until now, variations and combinations of bamboo species have not been carried out, especially about physical and mechanical properties. This paper...

The implementation of safety training is conducted to provide knowledge on the importance of safety for its employees. However, the implementation of safety training requires many consumable things such as a lot of Portable Fire Extinguishers (PFE) that increase the operational cost and trigger the environmental pollution. This research aims to des...

Gejala-gejala COVID-19 yang paling umum adalah demam, rasa lelah, dan batuk kering. COVID19 dapat menyebar dari orang ke oran...

Currently, business development, especially in the maritime sector, has quite rapid progress in Indonesia. Recently, the shipbuilding industry's development is an effort to improve competitiveness with the global market. With the increasing development of the shipbuilding industry in Indonesia, cost accounting as a cost information system is challe...

The significant increase of Teak wood price causes the high price of fishing vessels made from intact Teak wood so that it is necessary to replace the Teak wood as the main material in fishing vessels. The traditional construction of fishing vessels has negative impact such as decreasing quality of the material due to heat treatment of wood, so tha...

The shipping of the fishing boat is expensive and time-consuming, due to the long distance between the shipyard and the fishermen locations. The main objective of this study was conducted to analyze the technical and economic aspects of the traditional fishing vessel building using the modular system construction on laminated Mahogany and Teak wood...

In the shipping industry, especially shipyards which are used for building and repairing ships, a lot of labor is required. Due to a lot of labor, of course, makes the salary component to be a fairly large cost component in the company. Nowadays, many shipyards have turned to outsourcing-based shipyards, to reduce indirect costs. However, other shi...

Good quality, the right turnaround time, and affordable service costs are three important points that must be paid attention to in repair shops offering their services. In determining the selling price of repair services, companies need accurate information about the cost of goods manufactured, which consists of direct costs and indirect costs. In...

The ship building method used by many shipyards in the world has led to work effectiveness and efficiency. One of them is Product-Oriented Work Breakdown Structure Concept (PWBS). PWBS belongs in group technology. In this method the parts that will be produced for ship building are categorized based on the similarity in form and production process....

There are many criteria and methods that can be used to select the right supplier. Selection of a suitable supplier is needed, especially in the shipbuilding industry. Selection of suppliers is to reduce risky purchases, maximize price suppression with the best quality goods for buyers and establish long-term relationships between suppliers and buy...

In 2016, the number of fishing boats in Lamongan is 3,263 vessels, and 90 percent uses wood as the primary material for fishing vessels. The wooden boat repair activities in the Lamongan Regency are very high, considering the wooden vessels repaired regularly so that the condition of the vessels remains suitable for fishing activities in fishing. A...

Ship condition survey is a survey conducted by an Owner Surveyor for reporting the actual condition of the ship and parts. Presently, the condition survey is still done manually that Owner Surveyor has to survey based on survey list which is published by the ship’s owner company. The survey result will be presented in the form of a report, which wi...
