[ABSTRAK
Penelitian ini membahas tentang mechanical properties dari multimaterialberupa bahan polimer dan hydrogel dalam pembuatan konstruksi multiple layerdengan tujuan untuk mendapatkan sifat dan struktur mekanikal yang kuat sebagaiscaffold dalam aplikasi rekayasa jaringan lunak. Material yang digunakan dalampenelitian ini adalah PLA (poly lactic acid) sebagai bahan polymer dan gelatinsebagai hydrogel dengan tambahan starch komersil sebagai penguat gelatin.Terdapat dua metode dalam pembuatan scaffold yaitu casting untuk fabrikasiscaffold PLA dan gelatin, hybrid bioprinting untuk fabrikasi scaffold gelatin danstarch. Variasi pengujian dilakukan dengan memberikan perbedaan volumegelatin terhadap PLA dan perbedaan konsentrasi starch dalam campuran gelatin.Hal ini bertujuan untuk membandingkan mechanical properties scaffold yangdibentuk oleh PLA dan gelatin pada volume berbeda dan mechanical propertiesscaffold dari gelatin dan konsentrasi starch berbeda. Dari pengukuran danpengujian mechanical properties berupa uji tekan (compressive test) akandidapatkan bentuk struktur yang cocok dan sifat mekanik dari sistemmultimaterial scaffold. Untuk fabrikasi scaffold didapatkan nilai young modulus,E= 5.8 MPa pada scaffold campuran gelatin dan starch.

This study discusses about mechanical properties of multimaterial scaffoldwhich is constructed by polymer and hydrogel to get good mechanical propertiesand structure scaffold for soft tissue engineering application. The materials forthis study are PLA (poly lactid acid) as polymer and gelatin as hydrogel withcommercial starch. There are two methods to fabricate scaffold, they are castingfor PLA and gelatin scaffold fabrication and hybrid bioprinting for gelatin andstarch scaffold fabrication. Variation testing is done by giving difference volumebetween PLA and gelatin, and difference consentration of starch. From themeasurement and mechanical properties test by compressive test will be obtainedsuitable structure and mechanical properties for multimaterial scaffold. The lowestyopung moduslus is E=5.8 MPa which fabricated by gelatin and starch.;This study discusses about mechanical properties of multimaterial scaffoldwhich is constructed by polymer and hydrogel to get good mechanical propertiesand structure scaffold for soft tissue engineering application.
