An innovative of the portable electric tjanting pen

Abstract

This research aimed to develop a portable electric tjanting pen to replace the traditional tjanting pen, which requires lengthy preparation of melted wax and poses health risks to batik artisans. The study began with a problem analysis, followed by the design of the external structure and internal system, as well as an investigation into alternative materials for batik wax. The process included the construction and development of the portable electric tjanting pen and palm wax sticks, preliminary usability testing, and refinement of the device based on expert recommendations. Additionally, the study assessed the satisfaction of batik artisans using the portable electric tjanting pen. The research results demonstrated that the portable electric tjanting pen could effectively be used to apply wax on batik fabric. When operated at a current of 15 volts in combination with palm wax sticks, the device achieved a maximum continuous writing time of 6 minutes and a maximum writing distance of 1,662 centimeters at a speed of 277 centimeters per minute. The portable electric tjanting pen and palm wax sticks were found to be user-friendly, time-saving by eliminating the need to boil wax, cost-effective in terms of production, and posed no long-term health risks. Moreover, the device is convenient to carry, making it suitable for use by children, youth, and the elderly. The batik artisans who tested the device reported a very high level of satisfaction (x̄ = 4.44, S.D. = 0.69), equivalent to 88.8%.
