Abstract
Program 35.000 MW listrik merupakan bentuk komitmen pemerintah untuk menciptakan kemandirian energi dengan memanfaatkan secara optimal sumber-sumber energi terbarukan. PT Perusahaan Listrik Negara (Persero) menyiapkan pola khusus mengoptimalkan konsumsi gas alam cair untuk memenuhi kebutuhan listrik di Maluku, dan Papua guna mendukung 54 pembangkit listrik tenaga gas (PLTG). Tugas Akhir ini diharapkan dapat memberikan solusi untuk menciptakan sebuah sarana distribusi gas alam cair sebagai penunjang kebutuhan gas di Indonesia, khususnya di Langgur, Maluku Tenggara. Payload dari kapal ini merupakan kebutuhan gas alam cair yang digunakan sebagai bahan bakar Pembangkit Listrik Tenaga Gas (PLTMG) yang ada di Langgur. Ukuran utama awal kapalself propelled LNG barge ditentukan dengan penyesuaian jumlah dan ukuran tangki LNG yang digunakan berdasarkan kebutuhan LNG itu sendiri. Ukuran utama awal tersebut akan dilakukakan metode optimasi 256 ukuran utama. Dari 256 ukuran utama dipilih hambatan yang paling minimum. Setelah itu dilakukan perhitungan teknis berupa perhitungan berat, displacement, trim, freeboard, dan stabilitas. Ukuran utama yang didapatkan adalah Lpp = 63.9 m; B = 13.2 m; H = 4.15m; T = 2.65 m. Tinggi freeboard minimum sebesar 624.186 mm, besarnya tonase kotor kapal adalah 1367.831 GT dan kondisi stabilitas Self-propelled LNG Barge memenuhi kriteria Intact Stability (IS) Code Reg. III/3.1. Analisis ekonomis yang dilakukan adalah memperhitungkan biaya pembangunan (investasi), biaya operasional, serta analisa kelayakan investasi. Biaya pembangunan self-propelled LNG barge ini sebesar Rp 93.584.945.923 dengan estimasi pengambilan keuntungan bersih sebesar Rp 1.911.503.954 per bulan. Pada analisa kelayakan investasi didapat bahwa NPV sebesar Rp 62.082.334.764, IRR 24%, dan payback period pada tahun ke 5.

The 35,000 MW electricity program is a form of government commitment to create energy independence by making optimal use of renewable energy sources. PT Perusahaan Listrik Negara (Persero) prepares a special pattern to optimize the consumption of liquefied natural gas to meet electricity needs in Maluku and Papua to support 54 gas power plants (PLTG). This Final Project is expected to provide a solution to create a means of distribution of liquefied natural gas to support the gas needs in Indonesia, especially in Langgur, Southeast Maluku. The payload of this ship is a requirement for liquefie natural gas that is used as fuel for a Gas Power Plant (PLTMG) in Langgur. The initial main size of a self propelled LNG barge is determined by adjusting the number and size of the LNG tank used based on the LNG requirements themselves. The initial main measure will be carried out the 256 main size optimization method. the 256 main sizes selected the minimum resistance. After that a technical calculation is carried out in the form of weight, displacement, trim, freeboard, and stability. The main size obtained is Lpp = 63.9m; B = 13.2 m; H = 4.15m; T = 2.65 m. The minimum freeboard height is 624,186 mm, the gross tonnage of the ship is 1367,831 GT and the stability condition of the Selfpropelled LNG Barge meets the Intact Stability (IS) Code Reg criteria. III / 3.1. Economic analysis carried out is to calculate the cost of development (investment), operational costs, and investment feasibility analysis. The cost of constructing the self-propelled barge is Rp 93,584,945,923 with an estimated net profit taking of Rp 1,911,503,954 per month. In the investment feasibility analysis it was found that the NPV of Rp. 62,082,334,764,IRR of 24%, and payback period in the 5th year.
