Abstract
Dalam memenuhi kebutuhan serta permintaan pasokan energi listrik, terutama di wilayah yang sedang memiliki urgensitas pasokan energi listrik dan/atau wilayah yang tidak memiliki infrastruktur mumpuni untuk membangun serta mengoperasikan pembangkit listrik konvensional maka pembangkit listrik terapung bisa menjadi solusi. Namun dikarenakan bahan bakar yang dapat diangkut pembangkit listrik terapung terbatas, maka diperlukan pembangkit listrik terapung yang efisien dan hemat penggunaan bahan bakar. Efisiensi pembangkit listrik terapung dapat ditingkatkan dengan pemanfaatan limbah panas. Limbah panas berasal dari mesin dual fuel yang merupakan media pembangkit energi listrik pada pembangkit listrik terapung 100 MW. Limbah panas berupa energi potensial pada gas buang mesin dual fuel. Dari potensi energi panas gas buang, dapat didaur ulang atau dimanfaatkan kembali oleh metode steam rankine cycle menjadi energi listrik. Untuk mesin pembakaran internal (internal combustion engine), sekitar 25 % - 30 % energi bahan bakar dibawa ke lingkungan oleh gas buang. Tujuan dari pengaplikasian sistem pemulihan limbah panas (waste heat recovery system) di pembangkit listrik terapung adalah memanfaatkan sebanyak mungkin energi panas dari gas buang untuk menghasilkan energi listrik sehingga daya keluaran pembangkit listrik terapung bertambah. Pada penelitian dan penulisan tugas akhir, objek yang dikaji adalah pengaplikasian sistem pemulihan limbah panas jenis steam rankine cycle pada pembangkit listrik terapung 100 MW berbentuk tongkang yang terdapat mesin pembakaran internal (internal combustion engine) 7 x MAN 18V51/60DF. Untuk rencana pengaplikasian steam rankine cycle pada pembangkit listrik terapung, nantinya 7 x MAN 18V51/60DF akan diubah menjadi 6 x MAN 18V51/60DF. Setiap 2 x MAN 18V51/60DF akan dipasang sistem pemulihan limbah panas (waste heat recovery system) jenis steam rankine cycle. Perubahan yang dilakukan didasari oleh pertimbangan ketersediaan ruang pada pembangkit listrik terapung. Proses dalam pelaksanaan serta penuntasan yaitu menghitung potensi dari energi panas gas buang mesin dual fuel, kemudian merancang serta menentukan spesifikasi steam rankine cycle. Setelah melaksanakan serangkaian penelitian dan penulisan tugas akhir serta perhitungan, didapat bahwasannya setelah pengaplikasian steam rankine cycle efisiensi pembangkit listrik terapung secara keseluruhan meningkat 1.2 %.

In meeting the needs and demand for electrical energy supply, especially in areas that have the urgency of electricity supply and/or areas that do not have a qualified infrastructure to build and operate conventional power plant, floating power plant can be a solution. However, due to the limited amount of fuel that can be transported by a floating power plant, it is necessary to have an efficient floating power plant that saves fuel consumption. The efficiency of a floating power plant can be improved by utilizing waste heat recovery system. Waste heat comes from dual fuel engine which is a medium for generating electricity in a 100 MW floating power plant. Waste heat in the form of potential energy in dual fuel engine exhaust gas. From the potential of exhaust gas heat energy, it can be recycled or reused by the steam rankine cycle method into electrical energy. For internal combustion engines, around 25% - 30% of fuel energy is brought to the environment by exhaust gases. The purpose of the application of a waste heat recovery system in a floating power plant is to utilize as much heat energy as possible from the exhaust gas to produce electricity so that the output power of the floating power plant increases. In the research and writing of the final assignment, the object studied is the application of steam rankine cycle type heat recovery system in a barge-shaped 100 MW floating power plant that has a 7 x MAN 18V51 / 60DF internal combustion engine. For the plan to apply steam rankine cycle to a floating power plant, later 7 x MAN 18V51 / 60DF will be converted to 6 x MAN 18V51 / 60DF. Every 2 x MAN 18V51 / 60DF will be installed a waste heat recovery system, the type of steam rankine cycle. Changes made are based on consideration of the availability of space at a floating power plant. The process of implementing and completing is calculating the potential of dual fuel exhaust engine heat energy, then designing and determining the steam rankine cycle specifications. After carrying out a series of research and final assignments and calculations, it was found that after the application of steam rankine cycle the overall efficiency of floating power plant increased by 1.2%.
