Abstract

Exactly on the 17th of November, 2019, a new virus was just revealed in China and then spread to the whole world. Our government imposed a large-scale social restrictions (PSBB) to reduce the spread of the virus. This pandemic is detrimental to all sectors, including MSMEs. According to a Bank Indonesia (BI) survey released in March 2021, around 87.5 percent of MSMEs in Indonesia were affected by the COVID-19 pandemic. However, BI noted that there were 12.5% ​​who were not affected by the COVID-19 pandemic because the MSMEs were transforming with digitalization. Digitization can be started using digital marketing, but there are still many MSMEs who have not done digital marketing because of the lack of knowledge about doing digital marketing using social media, for example, YouTube. This research focuses on designing the user experience (UX) of the YouTube digital marketing learning application so that the system is made according to user needs. The method used is Human-Centered Design (HCD), which is a method of solving problems by involving a human perspective. This research will produce a high-fidelity prototype which will be tested using the heuristic evaluation method. There are 3 evaluators who are experts to conduct the test which resulted in 24 usability problem findings. The usability problem is categorized based on the severity rating and then corrected the problem.

Abstract

UD Sejahtera is an individual trading company that is engaged in the production and distribution of fine sea salt and sea salt. The company gets the supply of sea salt from suppliers, namely salt farmers, then distributes it to sellers. The production of fine sea salt is made from the result of the milling of sea salt. The problem related to salt marketing that occurs at the company is that the information of salt products cannot be accessed directly in the process of buying sea salt by customers. Another problem that the company faced is the ineffective data storage system. Sales reports, supply reports, and stock records are not up to date. If there is an error of data, it is necessary to check repeatedly against the documents that have been stored. Often the reporting is wrong and late, too much time of searching and adjusting the wrong data, as well as errors in recording the amount of remaining stock. This problem has the potential for losses to the company. This web-based system was built to overcome these problems. This system is expected to help the salt marketing process and record sales reports and supply reports. The process of developing this system is done using waterfall model. The stages performed in this research are literature review, requirements, design, implementation, testing, and conclusion. This system has been tested with unit, integration and validation testing.

Abstract

Lua Kreatif Teknologi Inc. is a technology company that focuses on software development. Lua Inc. currently requires an independent project management information system that focuses on the needs of project monitoring and helpdesk, which runs during the project executing and monitoring & controlling phases and during after sales. Therefore, this study describes the development of a web-based information system based on the needs of Lua Inc. This information system development model applies the SDLC (Software Development Life Cycle) waterfall and uses UML (Unified Modeling Language) for its design. The results of the needs analysis for the development of this information system produce a context for using the system which has 47 functional requirements and 5 non-functional requirements. There are adjustments for running business processes (as-is) with those offered (to-be) through an information system that is built and modeled with BPMN (Business Process Modeling Notation). The system implementation process implements a single page application architecture that communicates between the client (React.js) and server (Node.js) using the HTTP protocol without any reloading on the client. The testing method uses black-box testing by conducting validation tests on the functional system and UAT (User Acceptance Testing) which will be tested on stakeholders at Lua Kreatif Teknologi Inc.

Abstract

Google Meet and Zoom are video conferencing applications that are widely used during the COVID-19 pandemic as an alternative in conducting online activities. Both have differences in features and appearance which certainly make the user experience different. According to this, a study was conducted to compare the long-term user experience on the Google Meet and Zoom applications using the UX Curve method. There are 10 respondents for each application who are active students in the organization. Respondents describe their experiences in a UX curve template with 5 dimensions or points of view: general UX, attractiveness, ease of use, utility, and degree of use. Based on data collection, 50 curves were obtained for each Google Meet and Zoom application. The number of improving curve tendencies generated against Google Meet is more than Zoom, but on the other hand the curve is deteriorating and stable. This shows that Google Meet users are more satisfied with Google Meet, compared to Zoom users towards Zoom itself. This is supported by the percentage of positive reasons obtained for Google Meet, which is 75.2%, while for Zoom it is 73.6%. In addition, the Zoom application is proven to leave more impressions and experiences for users with a greater number of user reasons than Google Meet.
