Abstract

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.

Abstract

The potential for biodiesel to become the main fuel in the future seems to be getting brighter with the enactment of government policies related to the implementation of the Euro 4 standard. In addition, the government has also launched de-carbonization to reduce the greenhouse effect by referring to the International Maritime Organization (IMO) plan which sets a target of reducing world carbon emissions by 40% by 2030 and 70% by 2050. To answer this challenge, this research aims to find out the bio-diesel production process by utilizing waste cooking oil (WCO), the next step is whether the biodiesel produced has content properties that are following the quality standards set by the government, the final step is that the bio-diesel is tested on a test engine to know the value of the engine performance produced. In this research two types of methods are used to solve the problem, the first is the transesterification method, which is a method commonly used in the process of making biodiesel, this method utilizes a catalyst to separate pure biodiesel from glycerol, in this research using methanol and NaOH catalysts. The second method is the experimental method, which is testing biodiesel directly on the engine so that the resulting engine performance values including power, torque, and SFC can be known. The test obtained results in the form of content of fuel properties still included in government standards which include Density, Viscosity, Flash Point, Pour Point, and Cetane Number. The best torque value is in the B15 fuel variation at engine speeds of 1400 RPM and 1600 RPM, for the best effective power value results in the B15 fuel variation using engine speed of 1600 RPM, and the best specific fuel consumption value in the B15 fuel variation at 1000 RPM engine speed. So it can be concluded that mixing coconut cooking oil with pure cooking oil into biodiesel can be used as an alternative fuel and has a good impact on diesel engine performance.

Abstract

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.

Abstract

Penelitian ini bertujuan untuk menyajikan pendekatan sistematis dalam mengevaluasi keandalan sistem pelumasan pada kapal Sabuk Nusantara 43. Penilaian risiko dilakukan dengan menerapkan dua pendekatan, yaitu metode kuantitatif dan metode semi-kuantitatif. Pendekatan kuantitatif menggunakan pendekatan nilai numerik dalam analisis, sementara pendekatan semi-kuantitatif menggabungkan elemen analisis kualitatif dan kuantitatif. Metode ini digunakan untuk mengidentifikasi potensi kejadian yang tidak hanya berpotensi mengganggu operasional perpipaan, tetapi juga dapat berdampak pada aspek keselamatan dan lingkungan. Hasil penelitian mengindikasikan bahwa risiko terbesar terkait dengan instalasi pelumas pada kapal Sabuk Nusantara 43 terfokus pada komponen filter. Tingkat kerusakan komponen ini mencapai lima kali dalam satu tahun, dan berdasarkan analisis risk matrixplotting, risikonya masuk dalam kategori "major" (Tidak Diterima). Sebagai solusi pengendalian risiko yang direkomendasikan, dianjurkan pemilihan komponen saringan yang mematuhi standar yang berlaku, pelaksanaan perawatan berkala yang cermat, serta penghindaran penggunaan minyak pelumas yang sudah terlalu lama atau bekas. Dalam konteks ini, penelitian ini menekankan pentingnya evaluasi keandalan sistem pelumasan pada kapal Sabuk Nusantara 43 dengan memanfaatkan pendekatan metode kuantitatif dan semi-kuantitatif. Temuan utama menunjukkan bahwa risiko terbesar terkait dengan komponen filter, dan perbaikan serta perawatan yang teliti sangat diperlukan untuk meminimalkan risiko kerusakan. Sebagai rekomendasi pengendalian risiko, disarankan pemilihan komponen yang memenuhi standar yang berlaku, pelaksanaan perawatan berkala yang teliti, serta manajemen penggunaan minyak pelumas yang lebih efisien.

Abstract

In this research, the ship power plan which is the result of a conversion from a landing craft tank is designed to meet the electricity needs in areas affected by a disaster or electricity crisis. So far, the government has chartered a similar ship from Turkey which is used to meet electricity needs in Indonesian areas which have been affected by the disaster and electricity crisis. This ship is modified to carry an electric generator which can later be sent to areas that need it. Two main focuses are the goal of this research, the first is to find the value of the freeboard and the second is the trim of the ship after the redesign. To achieve this goal, in this study a numerical calculation method was used to calculate the freeboard and trim values according to applicable standards. The results of the analysis show that the freeboard value is still safe, with the actual freeboard value being greater than the required freeboard (0.8 m > 0.44 m). For ship trim, the bow trim condition is obtained with a smaller LCG-LCB difference than the 0.05% LPP value (0.912 < 0.923). By looking at the results of these measurements, the condition of the ship's freeboard and trim is still in a fairly good category even though it has been converted from a landing craft tank to a ship power plant. This study can provide a reference for ship design before converting the actual ship so that it can carry out trim and freeboard tests to prevent build failures.

Abstract

Perencanaan kelistrikan kapal harus dilakukan secara cermat dan akurat karena akan berpengaruh terhadap besar daya generator yang akan digunakan. Generator kapal dirancang untuk mampu mendistribusikan listrik untuk kebutuhan power (pompa), Penerangan (Lightning), Komunikasi dan Navigasi untuk berbagai kondisi pelayaran.  Sama halnya dengan kapal lainnya, TB Liberty  juga memerlukan distribusi tenaga dari generator untuk suplai kebutuhan listrik di atas kapal khususnya untuk penerangan kapal. Tujuan dari penelitian ini adalah untuk mengetahui besaran daya listrik yang dibutuhkan untuk distribusi penerangan diatas kapal dengan menggunakan lampu Light-Emitting Diode (LED). Metode yang digunakan adalah metode zonal cavity dengan konsep dasar membagi setiap ruangan menjadi tiga bagian yaitu height ceiling cavity (hcc), height room cavity  (hrc), dan height floor cavity (hfc) serta penentuan nilai iluminasi sesuai dengan standar yang telah di tetapkan oleh American Bureau of Shipping (ABS). Hasil penelitian menunjukkan bahwa besar beban listrik untuk distribusi penerangan pada kapal TB Liberty dengan menggunakan lampu LED yaitu deck buttom plane sebesar 0.633 Kw, pada main deck sebesar 0.6625 Kw dan pada geladak navigasi didapatkan sebesar 0.238 Kw. Penelitian ini mampu menjadi rujukan dalam penentuan kelistrikan di atas kapal khususnya untuk instalasi penerangan kapal.

Abstract

This research endeavors to explore a novel alternative fuel source by combining waste used cooking oil and corn oil to create a biodiesel blend. The study addresses two main objectives: first, to investigate the properties of used cooking oil biodiesel with the addition of methanol and NaOH catalysts, and second, to assess engine performance using the biodiesel blend. The experimental approach employs transesterification, varying the catalyst quantity during biodiesel production. Preceding diesel engine testing, properties such as viscosity are assessed, revealing improved values meeting Indonesian National Standards post-catalyst addition, albeit with a decrease in calorific value. Engine performance is then evaluated, demonstrating that as the catalyst content increases, torque and thermal efficiency decrease, while specific fuel consumption (SFC) rises. Notably, the study concludes that a higher catalyst ratio aligns fuel properties closer to government-set standards. The most favorable engine performance is observed in the B50 sample with a catalyst variation of 1000 ml of methanol and 25 g of NaOH, showcasing superior torque, thermal efficiency, and opacity values compared to higher catalyst variations. This research underscores the importance of catalyst optimization in achieving an environmentally friendly biodiesel blend with enhanced engine performance.

Abstract

Patrol Ship is a type of ship that prioritizes speed because of its function to secure water areas. This study uses patrol ship design as the object of study in determining the amount of ship resistance because this ship uses an ax bow hull form, the purpose of this research is to determine the effect of the Axe Bow type hull form on ship resistance, freeboard, and ship trim. The method used in this study is a simulation method with the help of maxsurf software. The results of this study indicate that using the Ax Bow Hull Shape model gives a resistance value of 245.9 kN with a speed of 25 knots, a freeboard value of 0.95, and a trim of 0.006575 m and is included in the "Accepted" category. With these results, the use of the axe bow model for patrol ships can be used as an alternative in selecting the hull shape of a fast ship.
