Abstract

Penelitian ini bertujuan untuk menentukan komposisi optimum sintesis produk kemasan makanan yang bersifat biodegradable dan dapat dimakan (edible film) serta karakterisasinya, sehingga mampu menggantikan material sintetis polipropilen. Edible film dapat disintesis dari bahan baku biopolimer pektin. Penambahan plasticizer gliserol dan variasi tepung tapioka dilakukan untuk memperbaiki karakter mekanik edible film pektin, sehingga memenuhi karakter mekanik polipropilen. Pengukuran karakter mekanik edible film pektin digunakan standar ASTM. Hasil rendemen tertinggi ekstraksi pektin adalah 0,8752 g pada suhu 70oC selama 120 menit. Karakterisasi sifat mekanik edible film pektin menunjukkan bahwa penambahan tepung tapioka 0 gram lebih berpengaruh terhadap penambahan nilai persen elongasi, sedangkan penambahan tepung tapioka 2,4 g berpengaruh terhadap nilai kuat tarik. Edible film pektin dengan kuat tarik tertinggi, yaitu 10,53 MPa pada penambahan 2,4 g tepung tapioka dan nilai persen elongasi tertinggi yaitu 20,47% pada penambahan 0 gram tepung tapioka. Hasil gugus fungsional FT-IR menunjukkan bahwa ekstraksi yang dihasilkan adalah pektin.

Abstract

This study was aimed at analyzing the effects of public perception and application of good governance principles, both partially and simultaneously, on an organizational performance. The research was conducted by using a questionnaire survey method. The samples in this study were 53 people and the sampling technique was simple random sampling. The data analyses were the correlation and regression analysis, t-test, F-test, and determination coefficient test. The results of the study proved that the public perception and application of good governance principles; both partially and simultaneously; had a positive and significant impact on organizational performance. The public perception had an effect of 60.5%, while the application of good governance principles had an effect of 55.1%. Meanwhile, those two independent variables had an effect of 88.6% on the dependent variable.
