Abstract

Indonesia as an archipelagic country consists of thousands of islands and has a large sea area so that the required mode of transportation is sea transportation as a means of mobility and driving national economic development. In addition, Indonesian waters serve as a liaison between cities, as well as between countries. As a border on the island of Sulawesi, the city of Bitung is a link between Indonesia and the city of Davao City in the Philippines. For all of this, security for shipping, especially at the border, is needed to support the smooth delivery of goods by using Ferry Ro/Ro ships so that sea transportation activities in general and trade and economic activities between the two countries can run smoothly because maritime safety greatly affects the continuation of development efforts

Abstract

Addressing global issues like climate change requires transformative solutions, and the shipping industry is no exception. Moving towards emission-free ship design has become a critical need, offering a chance to significantly reduce greenhouse gas emissions from maritime transport. In 2018, the International Maritime Organization (IMO) adopted a bold strategy to cut these emissions by at least 50% by 2050. Embracing renewable energy sources like batteries, wind, solar, and hydrogen fuel cells is key to achieving this ambitious goal. While electric ships powered by batteries are pioneering the way, meeting the IMO's target will necessitate radical changes in future ship design. Here, Indonesia holds a unique advantage, the legacy of the Sriwijaya Empire renowned for its mastery of wind-powered ships, resonates with this emerging era of green shipping. Abundant sunshine, strong wind potential, and growing expertise in maritime engineering position Indonesia to become a leader in the development and deployment of sustainable ship designs. Harnessing these historical and contemporary strengths, Indonesia can play a pivotal role in revolutionizing the shipping industry. By fostering collaboration between policy makers, researchers, and shipbuilders, Indonesia can spearhead the transition to a future where cargo ships navigate the oceans propelled by the clean power of renewable energy, leaving behind a legacy of environmental stewardship and economic prosperity. This paper estimates the energy consumption and power needs of Container ships on short inter-island routes in Indonesia, with a particular focus on the potential application of batteries in such scenarios. The initial design utilizes similar vessel data collected from various locations around the world. Our findings indicate that a container ship operating on the Jakarta-Semarang route would require batteries with a capacity of 15.25 MWh, Semarang to Surabaya route would require 12.20 MWh batteries, from Surabaya-Tanjung Benoa Bali route required 15.25 MWh, from Tanjung Benoa Bali to Ujung Pandang route require 21.35 MWh batteries, all with a capacity of 1.5 MWh each and from Ujung pandang – Ibu Kota Nusantara require 18.3 MWh. These calculations assume normal sea and weather conditions and a design speed of 10 knots. Implementing battery-powered Containers on these routes reduces the CO2 emission into the air as long as the ship route operates.

Abstract

Ice slurry muncul sebagai alternatif utama yang sangat mendukung kinerja nelayan dimulai dari bahan baku yang bisa langsung diambil ketika ditengah laut dan bertambahnya ruang pada kapal untuk penyimpanan ikan tersebut. Mesin Ice Slurry ini sebagai alat eksperimen untuk nelayan, nantinya pada penelitian kali ini akan dibuat variasi putaran pada pengaduk es (scrapper) dimana variasinya yaitu 500 rpm, 1000 rpm, 1200 rpm pada motor listrik yang kemudian direduksi oleh gearbox yang memiliki ratio 1 : 30 dan dibuktikan dengan volume air laut pada setiap variasi yang ditetapkan yaitu 20 liter dengan waktu 90 menit. Kualitas pendinginan yang dihasilkan dapat di tentukan oleh nilai COP yang mana hasil dari variasi tersebut kemudian dianalisis dan di dapat hasil nilai COP terbaik adalah 10,24 dengan putaran 1200 RPM.

Abstract

Kapal yang di analisa adalah kapal Ferry Ro-ro 2000 GT berlayar dari Bali menuju Lombok melalui jalur penyebrangan selat lombok dengan jarak tempuh 38 mil laut. Identifikasi penggunaan bahan bakar solar untuk operasional kapal, penting dilakukan pada kapal-kapal penyeberangan, khususnya sehubungan dengan usaha untuk memperoleh efisiensi penggunaan bahan bakar solar pada operasional kapal. Dalam pemecahan persoalan, analisa efisiensi diselesaikan dengan menerapkan metode analitik teknik, correlational-predictive, dan komparatif. Metode analitik teknik secara spesifik dipakai sebagai perhitungan karakter mesin dalam penggunaan bahan bakar, dan metode correlational- predictive dipakai sebagai metode pendekatan pada fenomena hubungan karakter mesin dalam penggunaan bahan bakar yang berbeda pada operasional kapal, sedangkan pada pendekatan metode komparatif akan dipakai untuk memberikan ilustrasi secara lebih lengkap pada sebuah studi kasus penggunaan solar sebagai bahan bakar mesin induk operasional kapal penyeberangan.

Abstract

The ballast control management system plays a vital role in maritime operations by ensuring vessel stability and safety while minimizing environmental risks associated with ballast water transfer. Effective ballast management regulates the filling and emptying of ballast tanks to maintain proper trim, draft, and balance during navigation and docking. With the enforcement of the Ballast Water Management (BWM) Convention by the International Maritime Organization (IMO), vessels must implement a Ballast Water Management Plan (BWMP) and maintain a Ballast Water Record Book to comply with international regulations. This study aims to develop a PLC- and HMI-based ballast control system that enhances monitoring and automation of ballast operations. The system is designed to improve control accuracy, diagnostic capabilities, and operational flexibility while ensuring compliance with IMO regulations. The research methodology involves system design, hardware integration, and software programming to create an automated control and monitoring solution. The PLC system utilizes digital inputs to operate pumps and valves, while analog sensors measure tank levels and pressure. The HMI interface displays real-time data, enabling seamless user interaction. The results demonstrate that the proposed system significantly enhances ballast operations by improving automation, control accuracy, and monitoring capabilities. The system ensures safe and efficient ballast management while facilitating regulatory compliance. These findings highlight the potential of PLC and HMI technologies in advancing maritime automation and control systems.

Abstract

The ship being analyzed is a Ferry ro-ro 2000 GT sailing from Bali to Lombok via the Lombok Strait crossing route with a distance of 38 nautical miles. Identification of the use of diesel fuel for ship operations is important for ferry vessels, especially in connection with efforts to efficiently use of diesel fuel in ship operations. In solving problems, efficiency analysis is completed by applying technical analytical, correlational-predictive, and comparative methods. The technical analytical method is specifically used to calculate engine characteristics in fuel use, and the correlational-predictive method is used as an approach method to the phenomenon of the relationship between engine characteristics in the use of different fuels in ship operations, in contrast, the comparative method approach will be used to provide a detailed illustration. More complete in a case study of the use of diesel as fuel for the operational main engine of a ferry ship.
