Abstract

This research tested an encapsulated cocoa husk extract formulated with maltodextrin and chitosan at an 8:2 ratio for use as a steel corrosion inhibitor. The method of weight loss in 0.75 M sulfuric acid, seawater, and peat water solutions was used to test inhibitors. The analysis indicated that inhibitor efficiency increased with increasing concentration. At the same time, its efficiency decreased due to longer immersion periods, reaching a maximum of 94.07% in peat water when a 2.5 g/L concentration of inhibitors was applied for 1 day. These results indicate significant potential for encapsulated cocoa husk extract as a natural corrosion inhibitor

<strong>Journal Summary </strong><strong><br /></strong><br />Jurnal Pengabdian Masyarakat Pinang Masak Abbreviated with JPM Pinang Masak (Journal of Community Service, Pinang Masak) is a scientific multidisciplinary journal published by Faculty of Sciences and Technology, University of Jambi (Fakultas Sains dan Teknologi, Universitas Jambi). It is in the national level that covers a lot of common problems or issues related to community services. The aim of this journal publication is to disseminate the conceptual thoughts or ideas and research applied results that have been achieved in the area of community services.Jurnal Pengabdian Masyarakat Pinang Masak (Journal of Community Service, Pinang Masak), contains various activities of UNJA community and even from other University communitu, in handling and managing the various potentials, obstacles, challenges, and problems that exist in society. Implementation of service activities also involve the participation of the community and partners. Service activities are organized into an activity aimed at improving the welfare of society.In the following year of publication, the journal is going to publish biannually (June and December). Any interested author could submit the manuscript following the <a href="https://online-journal.unja.ac.id/JPM/Guidelines" data-mce-href="https://online-journal.unja.ac.id/JPM/Guidelines">submission guidelines</a>.
