Abstract
Perwujudan delivery drone di Indonesia masih sangat minim pengembangan. Pengembangan yang paling rasional untuk dilakukan masa kini adalah dengan mengembangkan drone yang tersedia di pasaran menjadi drone yang siap delivery. Produsen drone di Indonesia sangat jauh tertinggal jika harus melakukan desain drone dari awal. Kalaupun ada anak bangsa yang mengembangkan delivery drone dari awal, cost yang didapat tidak mampu bersaing dengan drone harga rendah yang tersedia di pasaran. Hal logis yang paling mudah dan tepat kita lakukan adalah memodifikasi drone tersebut agar menjadi delivery drone. Langkah pertama adalah kita tambahkan bagian yang belum tersedia.Bagian drone tersebut adalah crane. Crane sangat penting untuk menjadi penghubung antara customer mengingat putaran baling-baling quadcopter cukup beresiko jika terlalu dekat dengan customer.Crane juga menjadikan pengiriman menjadi lebih cepat kareana quadcopter tak perlu mendarat sempurna terlebih dahulu. Crane perlu dibuatkan cover agar dapat terpasang pada quadcopter Syma X8pro yang digunakan dalam penelitian ini. Cover crane bermaterial PLA harus melalui proses optimasi untuk mendapatkan keringanan yang sekecil mungkin dengan memperhatikan batas tegangan yang diijinkan. Salah satu metode optimasi struktural yang dapat digunakan adalah optimasi topologi. Metode ini menghasilkan detail geometri yang cukup kompleks dan sulit direalisasikan dengan manufaktur konvensional. Melalui penggunaanaddictive manufacturing atau 3D printing, geometri yang kompleks dapat diproses dengan lebih singkat dan akurasi tinggi. Penelitian ini terdiri dari proses pemodelan desain cover-crane, simulasi tahap awal menggunakan simulasi static structural dengan software elemen hingga ANSYS yang meliputi pendefinisian model, meshing, set upconstaint, dan analisis hasil. Model awal exsisting diuji menggunakan software elemen hingga untuk mengetahui apakah tegangan dan defleksi yang dialami model mampu ditahan oleh material polylactic acid (PLA). Dilanjutkan simulasi optimasi topologi terhadap desain cover-crane dengan massa retain 80%, 65%, 50%, 35%, dan 20%. Selanjutnya dilakukan analisis simulasi tegangan dan defleksi menggunakan software ANSYS pada cover-crane kemudian dilakukan desain ulang pada model yang dianggap paling baik. Selanjutnya simulasi tahap akhir untuk cover-crane hasil desain ulang dilanjutkan analisis hasil akhir. Didapatkan nilai ekivalent stress sebesar 1,034 MPa. Masih dibawah dari nilai yield strength yang dimiliki PLA sebesar 54 MPa. Nilai defleksi sebesar 0,008 mm. Nilai maximum shear elastic strain sebesar 6,7782 x 10-6 mm/m m. Selanjutnya realisasi model dengan menggunakan 3D printer, dilanjutkan uji coba model secara langsung di lapangan.

The realization of delivery drone in Indonesia is still very low development. The most rational development to do now is to develop drones that are available on the market to be drones that are ready for delivery. Drone producers in Indonesia are very far behind if they have to do a drone design from zero. Even if there is a local brand who develops drone delivery from zero, the costs obtained are not able to compete with the low-priced drones available on the market. The logical and easiest thing we do is modify the drone that available in the market to become a delivery drone. The first step is we add the parts that are not yet available. That section is a crane. Crane is very important to be a liaison between the customer considering that the quadcopter propeller rotation is quite risky if it is too close to the customer. Crane also makes shipping faster because the quadcopter does not need to land perfectly. Crane needs to be made to cover so that it can be attached to the Syma X8pro quadcopter used in this study. polylactic acid (PLA) material crane cover must go through an optimization process to get the smallest possible lightness by paying attention to the allowable ekivalent stress limit. One of the structural optimization methods that can be used is topology optimization. This method produces geometric details that are quite complex and difficult to realize with conventional manufacturing. Through the use of addictive manufacturing or 3D printing, complex geometry can be processed with shorter and higher accuracy. This research consists of the modeling process of cover-crane design, early stage simulation using static structural simulation with software ANSYS which includes defining models, meshing, set upconstaint, and analysis of results. The initial exsisting model was tested using finite element software to determine whether the stress and deflection experienced by the model were able to be retained by PLA material. Next is topology optimization simulation of the design of cover cranes with retain mass of 80%, 65%, 50%, 35%, and 20%. Then the ekivalent stres simulation analysis and deflection using ANSYS software on the cover cranes were then redesigned on the best model. Furthermore, the final simulation for the re-designed cranes was continued with the analysis of the final results. Obtained stress equivalent value of 1.034 MPa. Still below the yield strength of the PLA of 54 MPa. The deflection value is 0.008 mm. The value of the maximum elastic shear strain is 6.7782 x 10-6 mm/mm. Next is the realization of the model using 3D printers then continued trial of the model directly in the field.
