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

SPOB (Self-Propelled Oil Barge) ship is useful for transporting oil. Due to certain requests, the owner and operator have converted SPOB into LCT. If before the conversion the ship transported oil, now the ship is transporting vehicles or heavy equipment on the deck. after the transfer of function from a SPOB ship to an LCT (Landing Craft Tank) ship, the cargo transported is different, the bottom is the part that is submerged in the water, so this part is vulnerable. Therefore, it is necessary to systematically predict the weight of the load that can be held by the ship at the bottom, this is so that there is no damage to the structure at the bottom of the ship which can harm the company from the ship owner. The purpose of this study is to find the maximum stress and strain that can be accepted by the ship and the value of the stress ratio (safety factor) in the bottom construction using the finite element method. The results obtained from the maximum stress and strain of the ship after and before conversion of 96.349Mpa, 272.56 Mpa, and 0.0013628 mm, 5.042 x 10-4 mm, safety factor according to BKI after and before conversion obtained 3.624 and 1.057, the safety factor according to the material criteria is 3.685 and 1.172, respectively, for the maximum deformation of the ship, the safety factor is 6.328 and 3.287 respectively

Abstract

Bulukumba merupakan daerah di Sulawesi Selatan yang memproduksi kapal kayu dengan bentuk chiri khas tersendiri. Bahan utama yang digunakan dalam pembuatannya adalah kayu. Ketersediaan material kayu merupakan salah satu variabel yang mempengaruhi harga pembuatan kapal, selain hanya bisa didapatkan dari luar daerah, jumlah material kayu relatif terbatas dengan adanya larangan penebangan liar yang sangat merusak hutan Indonesia. Minimnya bahan alternatif sebagai bahan utama pembuatan kapal kayu menuntut para pengrajin untuk cermat dan efisien dalam penggunaan kayu. Oleh karena itu sangat penting dilakukan kajian kebutuhan material kayu dalam pembuatan kapal kayu. Metode statistik digunakan dalam pengambilan sampel data konstruksi kapal dan metode analitis digunakan dengan memanfaatkan rumus simpson dalam menghitung bentuk dan volume konstruksi kapal kayu yang tidak beraturan sehingga kebutuhan material secara akurat diketahui. Hasil yang didapatkan semakin besar kapasitas kapal kayu maka kebutuhan material kayu pada lambung kapal semakin meningkat, dengan efisiensi material berbanding lurus dengan besar kapasitas kapal.

Abstract

currently general cargo transportation using containers is preferred. There are many reasons for choosing a container compared to normal cargo transportation, some of the reasons are having a standardized protection system, so it is safer to protect cargo. On the Samarinda - Kota Bangun route, transportation for logistics distribution uses the truck transportation mode. In this mode of transportation, it is highly influenced by traffic conditions and the roads in which it passes. For this reason, the use of self-propelled container barges (SPCB) is considered very efficient because it can overcome problems in container transportation rather than using land transportation modes. To get the design of a self-propelled container barge ( SPCB) the main size of the ship is obtained from the ratio of the main size of the ship. Then make a Line Plan with Maxsurf software and make a general plan with Autocad software and the main measurements obtained are; Lpp = 83.7 m; Lwl = 87.04 m; B = 12 m; H = 6 m; T = 4.5 m; VS = 10 knot; D = 4383 ton. With the number of containers as much as 140 Teus, the largest trim occurs at 0% DWT, namely 0.611 m stern trim. All the stability criteria of IMO A 749 (18) meet the 4 variations of the weight of the ship. In the DWT condition 100% the GZ max value is 0.512 m at an angle of 27.3○, and in the DWT condition 50% the GZ max value is 1.717 m at an angle of 38.2○ and at 25% DWT condition the GZ max value is 2.454 m occurs at an angle of 40.9○, and at 0% DWT condition, the maximum GZ value is 2.674 m occurs at an angle of 25.5○.

Abstract

Struktur gading pada kapal kayu tradisional memiliki bentuk khusus mengikuti bentuk lambung yang akan dikuatkan. Bentuknya yang melengkung menyebabkan pengadaannya membutuhkan waktu yang lebih lama sehingga berpengaruh pada waktu pembangunan kapal. Selain memperhatikan bentuk, ukuran penampang kayu juga menjadi salah satu pertimbangan pengadaan material kayu. Kejadian yang paling sering terjadi yaitu ukuran penampang tidak sesuai dengan perencanaan atau lebih kecil. Olehnya itu, pada artikel ini dilakukan simulasi penambahan ukuran penampang pada gading kapal menggunakan fiberglass. Penambahan dilakukan hingga mencapai luasan penampang yang dibutuhkan. Simulasi ini bertujuan untuk melihat kekuatan bending yang dimiliki antara gading kayu murni dengan gading kayu berlaminasi fiberglass. Simulasi ini dilakukan dengan menggunakan metode eksperimen di laboratorium menggunakan alat Destructive Test (DT). Penambahan laminasi fiberglass untuk menutupi kekurangan 10% luas penampang kayu. Dari hasil pengujian diperoleh hasil yang menunjukkan bahwa gading kayu berlaminasi fiberglass memiliki kekuatan bending yang lebih baik jika dibandingkan dengan kekuatan bending gading kayu utuh. Tingkat perbandingan kekuatan bending antara kedua gading tersebut mencapai 41.384%.
