Abstract

Batik is an original Indonesian heritage, that must be preserved and it is the mainstay for implementation of “Making Indonesia 4.0”. It was published many research about stamp batik manufacturing, but still have limitation of motive variation and slackly design process. This research aim to develop the way to making CNC program to be quickly, besides of high variation of batik motive. Source code in python programming language, was built for extension tool in inscape software. Extentension is used to create stamp point, depend on various motive size. Source code created in .py and .inx format will be save in “ekstensi” folder. Based on coordinate point of stamping in stamp batik, CNC program will be created, using “G-code tools” extension that was available in inscape software menubar. CNC programming used extension was built is measured about  time of process and compared to manual CNC programming. CNC program that has been built then tested in CAMotics software. The results of this research show that CNC program could maked with this extension for various dimension od batik stamp and in 2, 4, 6, 8, 10, and 12 meters of cloth length. CNC programming with extension developed, can reduce time up to 96.05%.

Abstract

In Tegal Asri RT 02 RW 03 Karanganyar, there are small and medium enterprises engaged in the business of producing roasted peanut shells.The production process is still done manually, so it can not meet the targeted production capacity.The purpose of the activity of designing and implementing a peanut washing machine is to increase the capacity of washing beans and save time. Before designing and implementing a peanut washing machine, it takes 75 minutes to wash 50 kg of peanuts. The results of the design of the tool and after application, the peanut washing process can produce 50 kg of clean beans with a total time of 20 minutes so that it can save 55 minutes of washing 50 kg of beans.
