https://journal.its.ac.id/index.php/jmest <p>In the fast-growing science and technology of marine-earth-related topics, we would like to launch a new international journal entitled MarineEarth Science and Technology Journal . This journal is aimed as a media communication amongst scientists and engineers in the fields of marine and earth science and technology and will receive research and technical papers to be reviewed by our editors and reviewers.</p> <p>The <strong>Journal of Marine-Earth Science and Technology</strong> is an international journal published <strong>three times a year</strong> by the <a href="https://www.its.ac.id/stkk/">Science and Technology Marine &amp; Earth Research Center, Institut Teknologi Sepuluh Nopember (ITS)</a>. It is open access to all scientists, researchers, students, and other scholars. The goal of this journal is to provide a platform for scientists and academicians to promote, share, exchange, and discuss various issues and developments in different areas of Marine and Earth. We receive manuscripts from reputable universities all over Indonesia, universities abroad, and other government and private institutes. All manuscripts must be prepared in English and are subject to a fair peer-review process.</p> <p><strong>Journal of Marine-Earth Science and Technology</strong> has been indexed by <a href="https://scholar.google.com/citations?user=sfo7nlsAAAAJ&amp;hl=en">Google Scholar</a> and <a href="https://garuda.kemdikbud.go.id/journal/analysis/22530">GARUDA.</a> Journal of Marine-Earth Science and Technology is also in the process of indexing SINTA</p> en-US kutama@na.its.ac.id (I Ketut Aria Pria Utama) tyowibowo1204@gmail.com (Setyo Wibowo) Mon, 22 Apr 2024 11:01:37 +0000 OJS 3.2.1.3 http://blogs.law.harvard.edu/tech/rss 60 https://journal.its.ac.id/index.php/jmest/article/view/1009 <p>This research investigates the implementation and environmental impact of "slow steaming" as an innovative method in maritime transportation, focusing on the route from Surabaya to Ambon. Utilizing a container ship model with a capacity of 100 TEUs, the study examines resistance data, engine power requirements, and the selection of a main engine aligned with sustainability goals. Slow steaming's influence on fuel consumption and emissions is analyzed, emphasizing cost-effectiveness and environmental benefits. The study extends to sailing route calculations, highlighting reduced oil consumption during slow steaming. Additionally, the research calculates the Energy Efficiency Existing Ship Index (EEXI), crucial for assessing and improving energy efficiency in compliance with International Maritime Organization regulations. The analysis of the container ship scenarios reveals optimal operational conditions and financial performance. In the Round-trip Full Load scenario, peak profitability is achieved at 77% engine load (10.5 knots), yielding Rp50,376,332,800.00 profit. In the Round-trip 1.5 Load scenario, maximum profit occurs at 54% engine load (9.5 knots), resulting in Rp21,245,220,000.00 profit. Bunkering costs, constituting 30-50% of the total cost, significantly influence economic dynamics. The Energy Efficiency Existing Ship Index (EEXI) peaks at 11 knots (31,166.06552) and reaches a minimum at 9.5 knots (22,518.17557). These insights offer guidance for optimizing maritime operational parameters and financial outcomes.</p> Haikal Anjasmara, Muhammad Dhaifullah, Lista Putri Adinda Rahmi Copyright (c) 2024 Journal of Marine-Earth Science and Technology https://journal.its.ac.id/index.php/jmest/article/view/1009 Mon, 22 Apr 2024 00:00:00 +0000
