Melt blending of polylactide and linear lowdensity polyethylene (LLDPE) was performed in an effort to toughen polylactide. In addition, two model polylactidepolyethylene (PLLA-PE) block copolymers were investigated as compatibilizers. The LLDPE particle size and the impact resistance of binary and ternary blends were measured to determine the extent of compatibilization. For the amorphous polylactide (PLA), toughening was achieved only when a PLLA-PE block copolymer was used as a compatibilizer. For the semicrystalline polylactide (PLLA), toughening was achieved in the absence of block copolymer. To decrease the variability in the impact resistance of the PLLA/LLDPE binary blend, as little as 0.5 wt % of a PLLA-PE block copolymer was effective. The differences that were seen between the PLA and PLLA binary blends were investigated with adhesion testing. The semicrystalline PLLA did show significantly better adhesion to the LLDPE. We propose that tacticty effects on the entanglement molecular weight or miscibility of polylactide allow for the improved adhesion between the PLLA and LLDPE.

Penelitian ini bertujuan untuk mengetahui pengaruh dari Current Ratio, Debt To Equity Ratio, Perputaran Kas dan Total Asset Turnover (TATO) terhadap Profitabilitas pada Perusahaan Food & Beverages yang terdaftar di Bursa Efek Indonesia (BEI) Periode 2012-2017. Penelitian ini mengunakan sampel sebanyak 11 perusahaan Food & Beverages yang terdaftar di BEI Pada tahun 2012 – 2017. Penelitian ini adalah penelitian kuantitatif. Data yang digunakan adalah data sekunder yang diperoleh dari situs www.Idx.co.id. Metode pengambilan sampel adalah Purposive Sampling. Metode analisis data yang digunakan terlebih dahulu adalah uji linear berganda. Hasil penelitian ini menunjukkan bahwa secara parsial Current Ratio berpengaruh positif dan signifikan terhadap Profitabilitas, Debt To Equity Ratio, Perputaran Kas dan Total Asset Turnover (TATO) tidak berpengaruh dan tidak signifikan terhadap Profitabilitas pada perusahaan Food & Beverages yang terdaftar di Bursa Efek Indonesia sedangkan secara simultan, semua variabel independen dalam penelitian ini berpengaruh terhadap Profitabilitas.
