Abstract

Corrosion is damage caused by chemical reactions between metal materials and other natural elements and is destructive to metal. Corrosion is a weakness in ships made of steel, namely because the rate of ship corrosion, fatigue life is reduced, tensile strength and other mechanical properties are reduced. Corrosion is concentrated on only certain parts. In metal corrosion current flow out onto other parts of the metal surface. Corrosion gastric plates result in reduction Hull panel strength, slowing the ship and reduces security guarantees. The hull must be protected from corrosive attacks routine to prevent loss of additional plates substantially due to seawater corrosion. For Prevent hull corrosion in the painting process for coating, cathodic protection process. In this article, a system for automatically detecting ship hull painting results using image processing is explained. This system will be developed into a portable system. The results obtained show that the system is able to recognize whether the painting results can be accepted or rejected. Accepted means no need to repaint. and if it is rejected, it means a repainting process is needed.

Abstract

The growth of UMKM in various sectors has triggered intense competition between these business actors. One of them is the craft sector. The use of social media is expected to boost turnover, but the benefits are still lacking. In the craft sector, the problem that arises on the MSME side is the cessation of production. This causes turnover to decrease and has an impact on decreasing profits. This dynamic system modeling is used to see how profit-increasing strategies can be carried out. Based on the dynamic system, there are several variables, namely the causal loop diagram (CLD) and the Stock Flow Diagram (SFD) that are built, there are 3 scenarios in increasing production profits, namely: increasing production, reducing the cost of tools and materials and the third is both taken simultaneously. From the simulation carried out, it was found that within a period of 12 months it was seen that increasing production by reducing the cost of tools and materials could increase sales so that income increased and profits increased. A process of identifying production process change variables is needed as one of the production process variables that was stopped.
