JoSTec starting June 30 2023 will be published in 2 issues, namely in June and December.</p> PT Inovasi Pratama Internasional en-US Journal of Science Technology (JoSTec) 2830-7275 https://ejournal.ipinternasional.com/index.php/jostec/article/view/979 <table width="579.0" cellspacing="0" cellpadding="0"> <tbody> <tr> <td valign="top"> <p>The objective of this research is to explore the design and development of an artificial intelligence-based recommendation system to enhance user experience on e-commerce platforms. The research methodology employed is qualitative research, a method used to gain in-depth understanding of social phenomena. The chosen type of research is a literature review, where in the researcher collects, studies, and analyzes written references or sources such as books, journals, articles, documents, and other significant sources of information related to the researched topic or title. Subsequently, the researcher analyzes and draws conclusions to find answers to the research questions. The research findings indicate that the development of an artificial intelligence-based recommendation system for improving user experience on e-commerce platforms is a relevant and pressing step. By comprehending various aspects discussed in the literature, the researcher can design a system that is not only accurate and efficient but also ethical, secure, and aligned with user needs. For future researchers, further studies are needed, and practical implementation steps will be crucial to translate literature findings into tangible solutions that can enhance the e-commerce landscape in the future.</p> </td> </tr> </tbody> </table> Afrizal Zein Copyright (c) 2024 Afrizal Zein https://creativecommons.org/licenses/by/4.0 2024-07-16 2024-07-16 6 2 53 57 10.55299/jostec.v6i2.979 https://ejournal.ipinternasional.com/index.php/jostec/article/view/1115 <p>Indonesia is the fourth coffee producer in the world after Brazil, Vietnam and Colombia. However, in the 2018-2021 period, the value of Indonesian coffee exports experienced a decline, which was in line with the low volume of Indonesian coffee exports in that year compared to the previous period, so that Indonesia's position fell from fourth to fifth as a coffee exporting country in the world. These various things could be due to the lack of downstream processing in coffee processing in Indonesia. The current problem is that there is no tool for the process of separating coffee into clear coffee, this tool is available abroad and the price is quite expensive. This research tries to make a clear coffee streamer and analyzes the production results of a clear coffee streamer. The results of the design of a clear coffee streamer tool using stainless steel material can be used with a capacity of 20 liters and a maximum heating temperature of 100^oC, while testing the production capacity of the clear coffee streamer tool produces data using a material volume of 1500 ml resulting in a production volume of 850 ml in a time of 75 minutes. Meanwhile, using a volume of 200 ml of material produces 950 ml with a time of 75 minutes.</p> Megandhi Gusti Wardhana Adi Pratama Putra Charis Fathul Hadi Muhamad Khoirul Anam Copyright (c) 2024 Megandhi Gusti Wardhana, Adi Pratama Putra, Charis Fathul Hadi, Muhamad Khoirul Anam https://creativecommons.org/licenses/by/4.0 2024-10-24 2024-10-24 6 2 58 63 10.55299/jostec.v6i2.1115
