Tugas Akhir (TA) ini merupakan pelaksanaan rancang bangun komponen aktuator dan selector valve model sistem hidrolik roda pendarat pesawat Grand Commander 680FL, khususnya rancang bangun komponen hidrolik. Rancang bangun tersebut bertujuan menunjukkan suatu cara alternatif dalam mempelajari dan memahami mekanisme kerja sistem hidrolik roda pendarat pesawat Grand Commander 680FL, selain dengan menggunakan alatnya secara langsung yang ada pada pesawat. Selain itu TA ini juga bertujuan merancang komponen aktuator yang dapat menghasilkan gaya untuk menggerakan komponen roda pendarat model. TA ini diselesaikan menggunakan dua metode yaitu metode analisis dan eksperimental. Metode analisis dilakukan melalui tahapan studi literatur, tahapan observasi & studi banding, tahapan analisis dan desain. Metode eksperimental dilakukan melalui tahapan manufaktur, tahapan pengujian, serta tahapan evaluasi dan troubleshooting. Komponen model sistem hidrolik yang berhasil dirancang dan dibangun yaitu komponen aktuator dan selector valve. Hasil yang didapat dari rancang bangun komponen aktuator dan selector valve ini, aktuator berhasil dimanufaktur dengan desain piston berdiameter 28 mm dan diameter silinder 32 mm dan komponen selector valve berhasil dimanufaktur dengan diamter 114 mm. Hasil TA ini diharapkan digunakan sebagai sarana pembelajaran bagi mahasiswa dalam mempelajari sistem hidrolik roda pendarat Grand Commander 680FL khususnya pada modul Sistem Hidrolik Roda Pendarat Pesawat Grand Commander 680FL. Kata Kunci: Skala, Rancangan, Pembuatan, Pengujian, Evaluasi dan Troubleshooting.

This Final Project (TA) is the implementation of the design and manufacture landing gear grand commander 680FL's hydraulic system model's component actuator and selector valve, especially the design of the hydraulic components. The design and manufacture aims to demonstrate an alternative way to study and understand the mechanism of aircraft landing gear hydraulic system of the Grand Commander 680FL, besides to using the equipment directly there on aircraft. Other than that, this TA also aims to design actuator components that can generate a force to actuate the model's landing gear components. This TA is solved by using two methods that is analytical and experimental methods. The analysis method through the stage of literature study, the stages of observation & comparative study, and stages of analysis & design. The experimental method through the stage of manufacture, the stages of testing, and stages of evaluation & troubleshooting. Components of the hydraulic system model successfully designed and manufactured, that is actuators and selector valve. The results obtained from the design of actuator and selector valve components, actuators successfully manufactured with design 28 mm diameter piston and 32 mm diameter cylinder and selector valve components successfully manufactured with 114 mm diameter. The results of this TA can be used as a learning tool for students to learn about the landing gear hydraulic system, especially on the Grand Commander 680FL module Hydraulic Systems Aircraft landing gear wheel 680FL Grand Commander. Keywords: Scale, Design, Manufacture, Testing, Evaluation and Troubleshooting.
