abstract: Polylactic acid (PLA) bioplastics are incresingly being developed due to its very high 
degradation ability. In this research, PLA bioplastics were made and the effect of the 
addition of 0,1%, 0,2%, 0,5%, and 1,0% Zinc Oxide (ZnO) and Magnesium Oxide (MgO) 
were analyzed through characterization and antibacterial testing. The bioplastics are made 
by the solvent casting method using chloroform solvent. Analysis of functional groups 
with FTIR shows that the addition of ZnO and MgO does not affect the PLA functional 
groups. Surface morphological and elemental composition analysis with SEM-EDX 
shows that ZnO and MgO are dispersed in PLA. The analysis of thermal degredation with 
TGA shows that the addition of ZnO and MgO decreases the thermal degredation of PLA. 
Tensile test analysis shows that the addition of ZnO and MgO increases the tensile 
strength of PLA, but excessive addition decreases its tensile stregth. Antibacterial test 
shows that the addition of ZnO and MgO increases the antibacterial ativity of PLA

Bioplastik Poli Asam Laktat/Polylatic acid (PLA) semakin dikembangkan karena 
kemampuan degradasinya yang sangat tinggi. Pada penelitian ini dilakukan pembuatan 
bioplastik PLA serta analisis pengaruh penambahan Seng Oksida (ZnO) dan Magnesium 
Oksida (MgO) dengan variasi konsentrasi 0,1%, 0,2%, 0,5% dan 1,0% melalui 
karakterisasi dan uji antibakteri. Metode pembuatan bioplastik dilakukan dengan metode 
solvent casting menggunakan pelarut kloroform. Analisis gugus fungsi dengan FTIR 
menunjukkan bahwa penambahan ZnO dan MgO tidak ada mempengaruhi gugus fungsi 
PLA. Analisis morfologi permukaan dan komposisi unsur dengan SEM-EDX 
menunjukkan bahwa ZnO dan MgO telah terdispersi pada PLA. Analisis degradasi termal 
dengan TGA menunjukkan bahwa penambahan ZnO dan MgO menurunkan degradasi 
termal PLA. Analisis uji tarik menunjukkan bahwa penambahan ZnO dan MgO 
meningkatkan nilai kekuatan tarik PLA, namun penambahan berlanjut menurunkan 
kekuatan tarik PLA. Uji antibakteri menunjukkan bahwa penambahan ZnO dan MgO 
meningkatkan aktivitas antibakteri PLA
