This review compares the quality control systems in traditional and modern shipbuilding, focusing on materials, processes, labor, cost efficiency, and product quality. Traditional shipbuilding, prevalent in regions like Indonesia, relies on manual craftsmanship and locally sourced materials, but struggles with inconsistencies in quality and meeting global standards. In contrast, modern shipyards employ advanced tools such as CAD, robotics, and non-destructive testing to achieve precision and efficiency, though at higher costs. The review explores the challenges faced by traditional shipyards i

Polyaniline grapheme nanocomposites can be synthesised by different annealing methods. Oxidative polymerization, emulsion polymerizations are some techniques used to synthesis polymer nanocomposite. DBSA, aniline, cationic and anionic surfactants are some reagent used as reagent for the preparation of polymer nanocomposite. Biocarbon based MoS2composite used for high performance supercapacitor application. Sustainable biocomposites form by Poly (trimethylene terephthalate) used in 3D printing. It can also be used in water filtration. Biochar can also be used to reduce pollutants from air, wate

The world economy is driven by various initiatives of private companies. Among these types of companies are SMEs, which represent 90% of established companies and contribute approximately 50% of GDP and 70% of formal employment; In the Peruvian case, the importance of SMEs is even greater since they represent 95% of formal companies and provide more than 85% of formal employment. Within the various productive sectors of Peru, veterinary which has seen significant growth in recent years; However, despite the dynamism of this sector, there are various factors that restrict the increase in profit

Corrosion in ship and offshore structures presents significant threats to structural integrity and safety, leading to considerable maintenance costs. In maritime environments, where steel and other metals are continuously exposed to harsh conditions, early and accurate detection of corrosion is critical for effective asset management. However, the degradation of image quality due to factors such as motion, low light, and environmental interferences like vibration poses substantial challenges for precise corrosion detection. This paper proposes an advanced image preprocessing method utilizing t

Steel corrosion presents a significant challenge to the durability and safety of infrastructure worldwide, with profound economic and safety implications. Traditional methods for corrosion detection and prediction often fall short in terms of accuracy, efficiency, and scalability, necessitating the exploration of advanced technologies such as artificial intelligence (AI). This paper provides a comprehensive review of AI applications in steel corrosion research from 2010 to 2024, focusing on detection and prediction methodologies. The review covers AI-driven techniques, analyzing their strength
