Laporan Tugas Akhir ini berisikan mengenai paparan hasil pelaksanaan Tugas Akhir dengan judul “Memfungsikan Kembali Master Power Panel Pada Sistem Kelistrikan Pesawat Grand Commander 680FLâ€�. Master power panel adalah peralatan yang berfungsi menerima energi listrik dari sumber (battery, external power unit, generator) dan selanjutnya mendistribusikan dan sekaligus mengontrol penyaluran energi listrik tersebut melalui sirkuit panel utama dan cabang ke sirkuit akhir beban yang berupa beberapa instrumen pesawat. Tugas Akhir ini diselesaikan dengan tahapan yaitu study literature, observasi, survei, penggantian/perbaikan, perakitan, pengujian, troubleshooting, dan pelaporan. Dari hasil pelaksanaan Tugas Akhir ini, master power panel pada sistem kelistrikan pesawat Grand Commander 680FL yang dimiliki oleh PSTA-JTM-POLBAN telah berhasil difungsikan kembali dan dapat dioperasikan didalam cockpit pesawat sesuai dengan Aircraft Maintenance Manual. Bersamaan dengan ini, sistem penerangan luar (anti-collison, landing gear light dan position) serta sistem external power juga berhasil difungsikan. Pemungsian kembali sistem penerangan luar dan sistem external power dilakukan oleh dua rekan penulis pada TA-nya masing – masing. Dengan demikian sistem kelistrikan pesawat Grand Commander 680FL yang dimiliki oleh PSTA-JTM-POLBAN akan dapat digunakan sebagai alat praktik yang lebih komprehensif pada perkuliahan Sistem Pesawat Udara dan Teknik Perawatan Pesawat Udara secara umum dan khususnya pada modul sistem kelistrikan pesawat udara. Kata Kunci: Observasi/pemeriksaan, evalusi, perbaikan, pergantian dan pengujian.

The final report contains the results of the implementation of the Final exposure with the title "Refuctioning Master Power Panel Of Systems Electrical Aircraft Grand Commander 680FL". Master power panel is functioning equipment receives electrical energy from the source (battery, external power units, generator) and then distribute and while controlling the distribution of electrical energy through circuit panel to the end of the load circuit in the form of some aircraft instruments. This final project completed by stages study literature, observation, surveys, replacement / repair, assembly, testing, troubleshooting, and reporting. From the results of the implementation of this final project, the master power panel of system electrical aircraft Grand Commander 680FL owned by PSTA-JTM-POLBAN has been successfully used again and can be operated in the aircraft cockpit in accordance with the Aircraft Maintenance Manual. Along with this, the outside lighting system (anti-Collison, landing gear light and position) and external power system also successfully functioned. Functioning system lighting outside and a system of external power carried by the two co-authors on TA her each, thus the electrical system of Grand Commander 680FL owned by PSTA-JTM-POLBAN will be used as a practice that is more comprehensive in the lecture System aircraft and aircraft Maintenance in general and in particular in aircraft electrical system module. Keywords: Observation / inspection, evaluation, repair, replacement, and testing equipment.
