The current condition of the digital economy in Indonesia reflects rapid development in recent years. One of the financial technology companies that plays an important role in advancing the digital economy in Indonesia is DOKU. Payment link, one of DOKU's products, is a product used by business entities to create a link that allows customers to make online payments using various available payment methods. However, based on the analysis revealed in the DOKU company's Payment Link Competitive Analysis document, it appears that DOKU Payment Link has a number of quite significant functionality gaps when compared to competing products. This final project aims to produce an interaction design to improve the no-code payment link product on the DOKU Merchant Dashboard that can meet user needs. The methodology used in this final project is user-centered design (UCD) with the international standard ISO 9241-210:2010. The final result of this final project is a high-fidelity DOKU Payment Link prototype with additional new functionality (Multiple Payment, Customize Payment Link, Open Amount, Simple Amount, Gather/Collect Customer Details, Predefined Template, Split Amount, Adjustable Quantity, Partial Payment, Attachments) as well as improving the interaction design of existing functionality by paying attention to the principles of usability heuristics and UI guidelines which have been tested in two iterations. Based on the evaluation results of the last iteration, it was found that the interaction design met usability goals because overall usability was quite good with SUS worth 67.5 out of a scale of 100 (OK, grade C) and SEQ worth 3.66 out of a scale of 5 (tends to be easy); having good utility with a satisfaction rate of 79.4%; effective to use with a task completion rate of 100% (with direct success of 96.88%) and a decreased number of errors from the results of the first evaluation of interaction design; efficient to use with avg time to complete per task which also decreased by 22.79% from the results of the first evaluation of interaction design. The improved interaction design also meets user experience goals because it is helpful with IMI: value/usefulness worth 5.2 on a scale of 7 and experiencing flow with an immediate success rate of 96.88%.
