Abstract

The use of a machine with Computer Numerical Control (CNC) technology is one of thealternatives in a manufacturing process. In the process of machining using Computer NumericalControlled (CNC), it is necessary to check the condition of the machine, because in machiningprocess requires good machine quality, tools using, cooling components, material in use andappropriate feeding procedure, so it can produce desired product. The common obstacles in CNCmachine is to overcome the corrosion that usually occurs in telescopic cover in CNC machine, so onthe method of forced flow (ICCP) with microcontroller system is applied. This method was chosenbecause it is easy to control the protection current that given to the system, this research using anodethat made from graphite material and cathode which is stainlees steel 304, with temperature variable40℃ and giving protection current 0,25 mA and 0,50 mA corresponds to the protection surface areaof 27.7172 cm2which requires a 0.066 mA current. Corrosion testing using the weight loss method ismeasuring the corrosion rate by measuring weight loss. From the previous test result usingimmersion test for 2 days corrosion rate that happened at 6,2008 mm / year then with rust electriccontrol test for 2 days resulted corrosion rate 2,5293 mm / year at current 0,25 mA whereas 0, 50 mAproduced a corrosion rate of 1.8580 mm / year. It can be concluded that the increase in the currentinput can slow down the rate of corrosion that occurs in SS 304 material.

Abstract

In a repair shipyard company there is a constraint, which in the field conditions require adevice that can be used to lift objects or goods that have a small capacity and can reach the height ofthe deck from the ship. But in the lifting products that already exist, when it has a small capacity thenhas a small lift height. And when it wants to take a lift height as its lift capacity also rises based onthe above problems it is necessary to design a new lift tool that can meet those needs.In this research,the lifting equipment is a mobile crane. So that it can be moved as well as the effectiveness of theplace of the shipyard. To meet the lift strength and lift level needed, it is necessary to analyze thestrength of the structure using the finite element method or FEM.In the design is expected to help forthe improvement and addition of existing facilities in the shipyard in Indonesia. In the results of theresearch, there are still some disadvantages, namely that in some calculations below the deck areignored, so that in the future there needs to be a calculation under the deck from the mobile crane.

Abstract

Along with the times and advances in science and technology, plastics are increasingly being used by people in various products because of their diverse interests. Many industries make plastic as the main raw material in the production process. Processing of plastic seeds until it became finished products can be done in many ways one of them is injection molding. But there are some obstacles when plastic products are made in large quantities, so they need to improve the quality of products they are produced.One way to improve the quality of products is by optimizing the parameters. Parameter optimization is a technique used in the manufacturing process to produce the best product. This study aims to optimize injection molding parameters such as injection time, injection pressure and holding time to optimize inner snap diameter and netto on pot cream products. Each parameter has 3 levels which are designed using Box-Behnken method. In this research using ANOVA method to analyze experimental data and the optimization of inner snap diameter and netto in injection molding process is done by using response surface method.Based on the results, it is known that the parameters of injection time, and holding time has an influence on the inner snap diameter. While for the netto all parameters have influence such as injection time, injection pressure, and holding time. For optimization, the configuration of injection time parameter is 3.74 seconds, injection pressure is 47%, and holding time is 1.5 seconds which produce 46.11 mm of inner snap diameter and netto 8.7 gram.
