Abstract

The ship production process at shipyards involves complex and critical information that must be managed effectively to ensure timely project completion. Ambiguities or delays in information exchange among departments can result in project setbacks and increased costs, which reduce revenue and undermine competitiveness. To address this, each department involved in ship construction must adopt an information system that ensures efficient communication both internally and across departments. Key information includes requirements for raw materials, consumables, workforce, production facilities, equipment, and the production methods used at each stage—factors that directly affect cost allocation. In many small shipyards across Indonesia, information is still processed and shared manually, leading to significant delays and inefficiencies. There is an urgent need for a digital information system tailored to the specific functions of each department and designed to facilitate smooth interdepartmental interaction. However, prior to system development, it is essential to understand and map the information flows within and between departments. This study focuses on the materials and interim products department, a critical part of the ship production process. The aim is to identify and map the internal information flows of this department and propose a suitable digital information system for implementation in small-scale Indonesian shipyards. By doing so, the research contributes to improving production efficiency and supports digital transformation in the domestic shipbuilding industry.

Abstract

The rapid population growth in Indonesia has significantly driven up energy demand, creating challenges in meeting these needs due to the declining availability of fossil fuels, the main source of power for most energy plants. Given Indonesia’s geographical position as a maritime nation with nearly six million square kilometers of ocean and over eighty-one thousand kilometers of coastline, the country has immense potential for harnessing ocean currents, waves, and tidal energy to develop renewable energy sources. Exploring these unconventional energy resources is crucial for meeting the country’s future energy demands. One of the most promising locations for Ocean Current Power Plants is the Sunda Strait. This research aims to model the ocean currents in the Sunda Strait, using Delft-3D software to assess its potential for Ocean Current Power plant development. The study also includes initial mapping of high-potential areas for energy production. Results from three observation points Sragi, Rimaubalak, and Sangiang indicate that the waters around Sangiang are most suitable for Ocean Current Power Plants with average currents of 0.86 m/s and a maximum of 4.77 m/s in 2023 also 0.938 m/s with maximum 5.20 m/s in 2024. For energy generation, the Gorlov turbine is particularly effective, producing 10642 kW in 2023 and 21285 kW in 2024, albeit with an efficiency of 36.52%. The Darrieus turbine showed a higher efficiency of 45.05%, though it generated slightly less power. Both turbines are deemed highly viable for further development in the Sunda Strait, offering a significant step toward Indonesia's renewable energy goals.

Abstract

Landing Platform Dock (LPD) ships as amphibious warships with complex accommodation systems, including lavatory installations, require effective and efficient installation methods. This study was motivated by the need to compare two lavatory installation methods, namely the conventional method and the modular method, in an effort to increase productivity and reduce the amount of rework in the construction of LPD ships. The research method used is the direct observation method at the national shipyard, with data collection through installation time records, number of man hours, material costs, and number of rework events. Data were analyzed using a quantitative descriptive approach by comparing these variables in each type of lavatory. In this study, 3 types of lavatory with different dimensions and shapes were used. The modular method which requires 10-14 days to complete has proven to be significantly more efficient in terms of implementation time compared to the conventional method with results of 19-25 days according to the type of lavatory. Likewise in the number of man-hours needed, which reached 384-480 JO for the conventional method and 264-456 JO for the modular method in the three types of work. The costs incurred for this production require IDR 67,880,890 - IDR 81,377,090 for the modular method and IDR 71,682,490 - IDR 87,713,090 for the conventional method. Thus, the modular method has proven to be more effective in increasing productivity and reducing the cost of installing a better lavatory.

Abstract

Resources contained along the coast and ocean play a significant part in fostering regional economic growth. Therefore, for the benefit of the community, both now and in the future, marine and coastal regions must be protected and used efficiently. Developing the blue economy sector is one promising way to promote economic growth in coastal and marine regions. One issue coming up has to do with the blue economy's governance and sustainability performance. The purpose of this study is to measure the sustainability performance of the blue economy and to identify the sectors that require development. Furthermore, this study aims to develop a governance model for the blue economy based on the TBL concept. Untung Jawa Island, located in Seribu Islands Regency - DKI Jakarta Province is the study area. FGD, questionnaires, in-depth interviews, and field observations were among the methods used to collect data. In order to address the research issues, this study uses the Interpretive Structural Modeling (ISM) and Blue Economy Valuation Toolkit (BEVTK) methodologies. According to the findings, four sectors might be developed: i.e., ship docking, aquaculture, port and sea transportation, and marine tourism. In this instance, ship docking performs the best in terms of environmental sustainability, port and sea transportation concerning social sustainability, and marine tourism as regards economic sustainability. Additionally, it was discovered that six factors: i.e., central and regional government policies, law enforcement and regulations, socio-cultural policies, community leaderships, and economic capacity and viability are crucial to the growth of a sustainable blue economy.

Abstract

This research explores the potential of Indonesian natural materials - specifically Nibung wood (Oncosperma tigillarium) and vegetable fibers (jute, ironwood) - for sustainable ocean structures. The literature review focused on: (1) mechanical and physical characterization of Nibung wood; (2) optimization of Nibung-fiber thermoplastic composites using the Taguchi-GRA method; (3) evaluation of jute fiber resistance to seawater uptake; and (4) innovation of traditional Bajau modular connection techniques. The narrative-thematic method categorizes the findings based on material characteristics, surface modification, structural performance, and marine tidal applications. Results showed Nibung wood has strength class II-III (density 0.53 g/cm³; MOE 5,848 MPa; MOR 4,325 MPa), optimized Nibung-rPP WPC (<2% water absorption, tensile strength >30 MPa), and jute fibers experienced ≤10% impact reduction after 84 days of sea immersion. Bajau- style modular joint detailing improved airflow and minimized moisture accumulation. Recommendations include integration of Nibung wood in local thermoplastic WPC, alkali-coupling treatment, and adaptation of modular joints for modern oceanstructures.

Abstract

Paint serves as a coating material that provides aesthetic value, adhesive strength, and protection to surfaces from environmental corrosion. The one of critical aspect is the paint and thinner ratio, which can influence adhesive strength and the performance of protection. This experimental study investigates the effect of varying ratios of epoxy zinc paint (Avantguard 750) and thinner (08450) on adhesion strength and drying rate. Paint was mixed with thinner at 10%, 20%, 30%, 40%, and 50% of the paint's volume. Steel plates were used as test specimens, coated via spray method. Adhesion quality was assessed using the “X–Cut Test” and “Cross Cut Tape Test” based on ASTM D3359 Methods A and B and the adhesion tests showed excellent results with a rating 5, indicating no peeling. Drying quality was evaluated using the “Solvent Rub” method according to ASTM D4752-20. Dry tests also have positive results with a rating 5 within 6 to 24 hours. The findings suggest that variations in thinner concentration do not significantly affect adhesion strength or drying time.
