Abstract

Efficient propeller performance contributes to better overall ship performance and speed. A well-designed propeller can optimize thrust generation, leading to improved maneuverability, responsiveness, and acceleration. It enables ships to maintain higher speeds while using less power, enhancing their competitiveness in the maritime industry. In this study, the Kaplan series propeller was analyzed by using Computational Fluid Dynamics (CFD). By modifying the angle of attack on the Kaplan propeller with 3, 4, and 5 blades, the distribution of the surface pressure, generated thrust, and torque value were easily identified and analyzed. The result shows that the change in the angle of attack influenced the pressure distribution on the back and face side of the propeller. The angle of attack is increased, and the pressure surface distribution also tends to increase. It has also affected the efficiency of the propeller performance which is expressed by the values of thrust propeller and torque. The more efficient the propeller performance, the less power it requires to produce the desired thrust.

Abstract

The purpose of this study is to analyze the effect of laying solar panels on the deckhouse of small fishing vessels 30 GT. The additional load above which causes weight gain and will affect the ship's center of gravity is became the first effect of Fishing vessel stability. The second effect is on how the fishing vessel performs when there is a solar panel on the vessel. The data were collected by measuring the stability according to A.N Kyrylo’s method with standard checks according to the IMO (International Marine Organization). Code on Intact stability calculated the ship motion by using the STRIP method and measuring the wave characteristics using the JONSWAP method with the help of Maxsurf software. The results of this research show that the installment of solar panels above the deckhouse does not really affect the stability, where the results were agreed to the IMO standard criteria. Moreover, the success of the fishing operation will be more visible if the vessels operated on waves under 2 meters due to the more stable movement according to its seakeeping performance .

For variations in ship speed given data such as length perpendicular (LPP) 28 meters, propeller rotation (N) 290 rpm and shaft horse power (SHP) of 452.5 Hp by setting speed values varying from 4 knots to 9 knots, the average propeller efficiency for the B4-40 type is 60% while the average trust or thrust of the ship is 5873.5 kg and the average trust coefficient is 0.28. Likewise for the B4-55 type, the average propeller efficiency is around 58.6%, then the average thrust for the ship is 5736.3 kg and the thrust coefficient for the ship is 6.6.

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

Kebutuhan tempat penyimpanan ikan hasil tangkap pada kapal-kapal nelayan semakin penting untuk menjaga agar tekstur ikan hasil tangkapan masih tetap dalam kondisi baik dan tidak rusak ketika sampai ke tangan pembeli. Pengunaan ice slurry (bubur es) menjadi pilihan terbaik karena Ice slurry dapat menjaga agar tidak ada udara diantara ikan dan es sehingga pendinginan ikan menjadi lebih cepat serta pertumbuhan bakteri menjadi lambat. Penelitian ini merupakan review variasi performa dan temperatur dari berbagai desain dan rancangan ice slurry terutama pada komponen evaporator yang telah dilakukan oleh tiga peneliti. Peneliti yang pertama adalah peneliti A (Fajri) dari UI menghasilkan temperatur mencapai -15 0C dalam waktu 7 jam, Peneliti B (Nasirin) dari IPB mencapai -4 0C dalam waktu 0.45 jam, dan Peneliti C (Suganda) dari ITS mencapai -2.5 0C dalam waktu 14 jam. Sehingga dapat disimpulkan bahwa performa desain terbaik adalah ice slurry oleh Peneliti A dengan rate temperature mencapai -2.14 0C/jam.

Abstract

Kebutuhan listrik pada sebuah kapal Perikanan adalah untuk lampu penerangan, pendingin ruangan, receptacle, alat bantu penangkapan, navigasi, dan refrigasi. Lampu merupakan alat bantu untuk menangkap Ikan. Karena kebutuhan lampu yang begitu banyak bagi penerangan maka perlu diketahui berapa kebutuhan listrik kapal ikan yang sebenarnya. Metode penelitian yang dilakukan adalah dengan memakai model percobaan. Data primer didapat dari lapangan yaitu di daerah ujung kulon dan pantai pelabuhan ratu kemudian dianalisis untuk mendapatkan berapa besar kebutuhan listrik pada kapal ikan di kedua daerah tersebut. Dari hasil percobaan yang dilakukan didapatkan untuk kapal 30 GT kebutuhan listriknya adalah 40122 wh sedangkan untuk kapal ikan 10 GT kebutuhan listriknya 480 wh.

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.
