Paper ini membahas tentang kekuatan poonton lift setelah ditambahkan upper deck dan lower deck yang berfungsi sebagai lantai penunjang yang menjadi pijakan para worker ketika reparasi kapal dilakukan di atas poonton lift. Tujuan penelitian ini mengetahui nilai kekuatan poonton lift setelah dilakukan penambahan lantai penunjang dengan memperhatikan faktor safety kontruksi. Metode yang digunakan adalah Shear Force Bending Momen (SFBM) dengan pendekatan numerik. Hasil penelitian yang didapatkan bahwa untuk ukuran lower deck yang tepat pada poonton lift yakni lebar 7.082 m dengan ketebalan plat 8 mm dan menggunakan penampang profil berukuran L 100x65x11. Sedangkan untuk ukuran upper deck yang tepat memiliki lebar masing masing 1.46 m pada sisi kiri dan sisi kanan, ketebalan plat 7 mm, serta memiliki profil berukuran L 180x90x10. Pada konstruksi poonton lift untuk masing-masing skenario operasi dideteksi tegangan maksimum dengan skenaria berisi muatan kapal (σ) = 107.17 MPa pada bottom dan (σ) = 214.56 MPa pada deck. Sedangkan tegangan maksimum dideteksi dengan skenario tanpa muatan kapal yakni (σ) = 57.66 MPa pada bottom dan (σ) = 115.45 MPa pada deck. Untuk nilai safety factor pontoon lift setelah penambahan upper deck dan lower deck didapatkan relatif aman karena berada pada nilai minimum 1.29.

Tourism ship with the Phinisi ship concept for the Selayar Islands tourist area are designed to increase the number of tourist attractions in the area. With beach tourism destinations and coral reefs, the Selayar region is very possible to become an alternative tourist destination in Indonesia besides Bunaken, Raja Ampat, Labuan Bajo, and the island of Bali. This ship is designed with wood materials and carries the theme of the traditional Phinisi ship which is the hallmark of ships made by the Bugis-Makassar tribe since 3000 years ago and has been recognized by UNESCO as one of the world's cultural heritage (Art of Boatbuilding in South Sulawesi). This study aims to obtain a tourist ship design that can be an attraction for tourists to vacation in the Selayar Islands. The method used in this study is the parent ship design approach method, this method is very commonly used in the ship design process, namely by using a comparison ship as a reference in the design of a new ship. The main ship dimensions obtained from this research are Loa = 26 m, B = 6.1 m, H = 2.48 m, T = 1.6 m, Vs (max) = 10 Knots, and Crew = 6 persons. The room on the ship is made like a classy hotel room and other services can pamper tourists.

The 70 GT multipurpose fishing vessel is a type of vessel designed to operate longer at sea. This ship has a relatively wider cargo space with a variety of fishing gear (multipurpose). The ship is propelled by a 283 kW diesel engine and the source of electric power is supplied by a 20 kW diesel generator. The purpose of this study is to determine the amount of electric power used for ship lighting. The method used is the lumen method or the zonal cavity method. This method is used to determine the proper lighting standards on board according to regulatory standards from the American Bureau of Shipping (ABS) class. The results of the study showed that the total electric power needed for lighting on board was 0.4 kW. LED lights are an alternative in determining the type of lighting that is energy efficient and durable on board.-

Ferry accidents in Indonesia happen not just once or twice, but more than that. This is reinforced by statistical data on shipping transportation accidents. Shifting or overturning of the vehicle to the side of the ro-ro ferry has a big hand in causing the ship to capsize, and eventually an accident occurs. This study aims to determine the characteristics of the lateral and vertical acceleration of vehicles based on their location on the car deck under the influence of side waves. The method used is strip theory with the help of Maxurf software, which adheres to the B-spiline mathematical equation. The results of the study detected that vehicle positioning on the ro-ro ferry car deck significantly affects the value of vertical acceleration and lateral acceleration due to rolling motion. This is one of the parameters that can cause a vehicle to roll over.

Balikpapan City has an area of 508.9 km2 which has 646,727 people living here. Balikpapan City is also known as a port city because it has two domestic ports namely Kampung Baru Port and Semayang Port. Currently, the port of Kampung Baru is still active in carrying out daily activities, namely the klotok boat crossing and also the dock for motor boats berths. The condition of mobility for crossing vessels in the port of Kampung Baru that uses boat klotok is inadequate due to the lack of supporting components for access to the ship so the safety of this port is questioned. besides that, klotok ships are also only able to carry a maximum of 21 passengers and 5 motorcycles and access to loading and unloading exits is very unsafe. The purpose of this study is to design a crossing ship that can be used safely for transportation for passengers and motorcycles that will pass the sea lane for crossing to the North Penajam Paser area. The ship is designed to have an easy access door or ramp door for passenger and motorcycle mobility to improve the safety of crossings at the port of Kampung Baru. The parent Design Approach method is used in this project, this method is one way of designing a ship using comparison or comparison, namely by taking a ship that is used as a reference for a comparison ship that has the same characteristics as designed ship. The main focus to be achieved in this research obtained a General Arrangement which has more cargo than the klotok ship with a capacity of 25 passengers and 10 motorcycles, and the dimension of the ramp door used in this final project is L 1.50 m and B 1.50 m. The Principal dimension of the ship obtained in this research is Loa = 12.50 m, Lpp = 11.50 m, Lwl = 11.96 m, B = 5.75 m, B1 = 1.64 m, H = 1.8 m, T = 0.85 m, Cb = 0.56, Vs = 15 Knots. The results of this study provide a good idea of the modernization of a comfortable ferry fleet for this area.

Mayoritas kapal kapal nelayan di Indonesia khususnya yang berukuran 30 GT masih memiliki banyak kekurangan seperti kapasitas muatan yang sedikit, jarak tempuh pelayaran yang relatif pendek, desain kapal yang masih kurang ekonomis dan boros bahan bakar serta jumlah armada yang masih sangat sedikit dibandingkan dengan potensi perikanan yang melimpah di laut Indonesia khususnya wilayah pengelolaan perikanan Republik Indonesia (WPP-RI) 713 sehingga mendasari pentingnya dilakukan modernisasi kapal nelayan tradisional. Ukuran utama kapal diambil dari data satu kapal ikan yang terdaftar pada Biro Klasifikasi Indonesia. Desain kapal ini dilakukan dengan bantuan software Maxsurf Modeler dan AutoCAD student version. Adapun perencanaan mesin utama dilakukan dengan bantuan software Maxsurf Resistance dengan menggunakan metode perhitungan hambatan van Oortmerssen sehingga didapat kebutuhan daya mesin sebesar 99.733 HP setelah ditambah margin 15%. Kemudian dipilihlah mesin dengan Merk Yanmar dengan daya sebesar 110 HP. Dari hasil penelitian didapatkan hasil desain lines plan dan general arrangement kapal ikan multipurpose 30 GT dengan alat tangkap purse seine dan squid jigging yang dilengkapi dengan mesin Yanmar bertenaga 110 HP.

To address the challenges faced by the government in the realm of petroleum imports, a promising strategy was adopted in the utilization of biodegradable and renewable sources of biodiesel, such as coconut oil. This research employed two distinct methodologies: Transesterification for biodiesel synthesis and a comprehensive assessment of fuel properties. Subsequently, an experimental phase assessed biodiesel within an engine environment to analysis performance metrics. Results showed that B30 (30% coconut oil, 70% diesel oil) has density of 0.850 g/cm³, B50 (50% coconut oil) at 0.861 g/cm³, and B100 (Pure coconut oil) at 0.893 g/cm³. The values differed from regional standards. As per ASTM D6751, B30 has a viscosity of 2.31 cSt, B50 3.22 cSt, and B100 is 7.02 cSt. Engine performance revealed B50 with the highest torque at 11.787 Nm, while B0 (pure hydrocarbon diesel) has a thermal efficiency of 38%. B0’s lowest SFC (Specific Fuel Consumption) is 261.12 g/kWh at 2000 watts load and 1000 rpm. Biodiesel coconut oil provided comparable power and torque (0.3% difference from B0) but consumed more fuel (21.6 % higher usage than B0). Keywords: Biodiesel, Coconut oil, Engine performance, Fuel properties, Transesterification.
