Abstract

Ketergantungan yang tinggi pada sumber energi fossil masih menjadi permasalahan utama penyediaan energi nasional dimana penggunaan BBM yang tinggi mengakibatkan pengurasan devisa negara akibat impor, dan juga peningkatan emisi gas rumah kaca (GRK) Penggunaan BBM dan batubara yang masih mendominasi pada sektor industri dan transportasi tidak sejalan dengan pengeratan regulasi IMO Annex VI yang menargetkan pengurangan intensitas karbon per-transport sebesar 40% di 2030 sedangkan terdapat cadangan LNG nasional dimana dalam penggunaanya merupakan energi bersih dibandingkan dengan minyak yang memiliki 20% reduksi karbondioksida sehingga melalui tugas akhri ini, akan menghasilkan desain kapal mini-LNG berkapasitas 6000 Cubic Meter (CBM) dengan analisa pemilihan bahan bakar dan sistem propulsi yang cocok untuk kapal dengan pilihan sistem bahan bakar dual-fuel LNG dan propulsi elektrik serta kapal didesain dengan konsep futuristik Greenship dengan menggunakan Multi Criteria Decision Making (MCDM) metode Analytical Hierarchy Process (AHP) sehingga menggambarkan kapal LNG masa depan yang berkelanjutan sebagai upaya pemasokan LNG optimal dan ramah lingkungan. Hasil MCDM didapatkan diesel konvensional tetap di posisi teratas, walaupun begitu untuk mencapai pemasokan yang ramah lingkungan maka digunakan peringkat kedua yaitu dual-fuel electric. Didapatkan juga LOA 106 meter, LPP 99 meter, B 18 meter, H 9 meter, T 6 meter, Kecepatan dinas (Vs) 12 knot, Cb 0,745, Cp 0,748, dan Cm 0,995. Ukuran cylindrical tank LNG adalah panjang 31 meter dan lebar/tinggi 12 meter. Penggunaan standar IMO A.749 menunjukkan stabilitas kapal mini LNG carrier memenuhi keenam standar kriteria pada tiap kondisi muatan. Menetapkan margin sebesar $2 USD/MMBTU untuk biaya transportasi sehingga menghasilkan Total NPV dikisaran Rp54,982,574, IRR sebesar 12.6%, ROI 26%, dan payback period di 7 tahun kontrak yang dimana jika menggunakan skema balloon payment pada akhir tenor akan sudah balik modal.

High dependence on fossil energy sources is still the main problem of national energy supply where high fuel use results in a drain on foreign exchange due to imports, and also increases greenhouse gas (GHG) emissions The use of oil and coal which still dominates the industrial and transportation sectors is not in line with the tightening of IMO Annex VI regulations which target a 40% reduction in per-transport carbon intensity by 2030 while the national LNG reserves are able to be used for a cleaner energy source compared to oil which has 20% carbon dioxide reduction so that through this final project, will produce a mini-LNG ship design with a capacity of 6000 Cubic Meters (CBM) with an analysis of fuel selection and propulsion systems suitable for the ship with a choice of dual-fuel LNG fuel systems and electric propulsion designed with the Greenship futuristic concept using the Multi Criteria Decision Making (MCDM) Analytical Hierarchy Process (AHP) method so that it produces a sustainable future LNG ship as an effort to achieve optimal and environmentally friendly LNG supply. The MCDM results obtained conventional diesel remains in the top position, however, to achieve environmentally friendly supply, the second rank is dual-fuel electric which will be used further in this study. LOA 106 meters, LPP 99 meters, B 18 meters, H 9 meters, T 6 meters, service speed (Vs) 12 knots, Cb 0.745, Cp 0.748, and Cm 0.995 were also obtained. The cylindrical size of the LNG tank is 31 meters long and 12 meters wide/height. The use of the IMO A.749 standard shows that the stability of the mini LNG carrier meets all six standard criteria in each loading condition. Setting a margin of $2 USD/MMBTU for transportation costs results in a Total NPV of around Rp54,982,574, an IRR of 12.6%, an ROI of 26%, and a payback period of 7 contract years, which if using a balloon payment scheme at the end of the tenor will be paid back.
