Abstract

West Java has a centre for craftsmen who have a variety of motifs drawn from their regional potential. One of them is Ciamis batik, but now with the pandemic of the Corona 19 virus, it has had a tremendous impact on the macro and micro industrial economy in the development of the batik business. More and more are stopping their business. So it is feared that Ciamis batik motifs are increasingly rare in the market. Through Turtle graphics, existing batik motifs are made in the form of vector images to be preserved by utilizing digital technology. This research has the aim to that the Ciamis batik motif can be made into a visual language through the digitalization process using the MuPAD programming language. The benefit is to document and reintroduce Ciamis Batik motifs that are almost extinct. The method used is a digitalization experiment through the Lindenmayer System. Ciamis batik samples selected motifs that have repetition in the form of a repeating pattern. Based on the research, the Ciamis batik motif can be made using the technique of arches, horizontal lines, vertical lines, and rotation. The conclusion of this research is that batik motif design can use the Lindenmayer System program as a blueprint and can be implemented on Indonesian batik.  This research contributes to the efficient documentation of batik motifs in digital form with good quality so that they can be implemented in the creative industry.

Abstract

Designing motifs is still mostly done manually, using a pencil and then drawing on paper. The purpose of this research is to offer a solution in making geometric motifs by utilizing algorithmic art produced through computer technology. This method is a combination of the use of algorithmic art and the design used in making geometric motif designs. Algorithmic Art is a subset of generative art that is the result of an algorithmic process and is designed by the artist and usually uses a random process to generate variations based on external input. The results of this study are geometric motifs using the algorithmic art method. Geometric motifs can be applied to fabrics, decorations, and others.

Abstract

OSTR stands for Open Source Turtle Robot is a turtle robot whose hardware and software are open source and published by MakersBox located in Adair Village, OR, United States of America. In this study OSTR will be developed into an Wireless Robot Plotter that can draw and write and is equipped with computer software to support the needs of the learning process in understanding logical thinking for students. In this study, a wireless Robot Plotter design has been successfully designed to support students' understanding of logical thinking. A logical thought in the form of syntactic logic steps "turtle graphics" is inserted into the application interface (created in visual basic language), then the logic steps are translated in the form of an image that can be viewed on the monitor screen and sent wirelessly to the Robot Plotter (using nodeMCU ESP8266-12 as the processor) to be drawn by the Robot Plotter. From the tests, the realized wireless Robot Plotter successfully drew according to the logic steps instructed through the created interface application. The research urgency is to train logical thinking by designing a robot plotter so that abilities and skills are sharpened and the plotter robot used to draw basic batik motifs can be utilized by the creative industry.
