Abstract


ABSTRAK

Pengembangan Unmanned Aerial Vehicle (UAV) membutuhkan material struktural yang ringan, kuat, dan ramah lingkungan. Penelitian ini bertujuan menganalisis ketahanan impak komposit hibrid dari Serbuk Serat Batang Pisang (SSBP), Serbuk Fiberglass Woven (SFGW), dan Serbuk Carbon Kevlar (SCK) dengan matriks resin epoksi 34% sebagai alternatif material body UAV. Penelitian menggunakan metode eksperimen dengan variasi ukuran partikel Mesh 30 dan Mesh 40 serta tiga komposisi SSBP–SFGW–SCK, yaitu 10%:22%:16%, 22%:10%:16%, dan 22%:16%:10%. Pengujian dilakukan menggunakan metode Charpy-V berdasarkan ASTM D6110 dan dianalisis dengan ANOVA dua arah serta Tukey HSD. Hasil menunjukkan ukuran mesh tidak berpengaruh signifikan terhadap energi impak (F = 0,364; p = 0,558), sedangkan komposisi layer berpengaruh signifikan (F = 13,497; p = 0,001). Komposisi 22% SSBP–16% SFGW–10% SCK menghasilkan rata-rata energi impak tertinggi sebesar 2,3336 J. Tidak terdapat interaksi signifikan antara ukuran mesh dan komposisi layer (F = 3,190; p = 0,077). Komposisi tersebut menjadi variasi paling optimal berdasarkan hasil statistik dan pengamatan patahan.

ABSTRACT

This study aims to analyze the impact resistance of a hybrid composite made from Fiber Banana Stem Powder (SBP), Fiberglass Powder Woven (SFG), and Carbon Powder Kevlar (SC) with a 34% epoxy resin matrix as an alternative material for UAV bodies. The experimental method was used with Mesh 30 and Mesh 40 particle sizes and three SSBP–SFGW–SCK compositions: 10%:22%:16%, 22%:10%:16%, and 22%:16%:10%. Impact testing was conducted using the Charpy-V method based on ASTM D6110 and analyzed using two-way ANOVA and Tukey HSD. The results showed that mesh size had no significant effect on impact energy (p = 0.558), while layer composition had a significant effect (p = 0.001). The 22% SSBP–16% SFGW–10% SCK composition produced the highest average impact energy of 2.3336 J. No significant interaction was found between mesh size and layer composition (p = 0.077). Therefore, the 22% SBP–16% SFG–10% SC composition was identified as the most optimal variation.

 

Keywords: hybrid composite, SBP, fiberglass, carbon, impact energy, UAV.
