Technology has become a major component in every aspect of human life, and learning resources had included in that aspect. This issue described media for learning the “Jaman-Now App Permilang (JNAP)” can have an effect on students’ cognitive and their motivation in the learning process. The quantitative approach was the method used in this study, where this research was a part of the development research conducted by researchers, in which this research presentation specifically explained aspects of the effectiveness of the product being developed. Product feasibility tests are carried out in the school environment through two processes (limited & extensive test). Those processes were used with observation, testing, and questionnaire techniques as a measure of product success. The feasibility of this research focused on the effectiveness of the product in chemical learning where this effectiveness is assessed as an indicator of product feasibility with a valid instrument (cognitive tests, questionnaire). Statistical data revealed that the average N-Gain in the 1st process has a point of 0.25 (low), the 2nd process was 0.42 (medium), and very good criteria for the motivation aspect. The results indicated that the product has a good enough impact on the co-positivity and motivation of students, although the visualization of the values shown in the medium criteria. In other words, the product has the potential to become one of the strategies in improving the quality of chemical learning, assessment for chemistry learning, strengthening their cognitive, and guidelines for students in reflecting themselves in an understanding of the chemical material.
Abstrak-Pengemasan merupakan salah satu faktor penting yang diperlukan pada produk makanan. Jenis pengemasan yang sering digunakan adalah plastik, namun sifatnya yang nonbiodregadable akan memunculkan permasalahan baru. Oleh karena itu dikembangkan edible film, yang merupakan suatu kemasan primer ramah lingkungan serta dapat dimakan. Salah satu sumber daya alam lokal Kalimantan Selatan yang dapat digunakan sebagai bahan baku pembuatan edible film tersebut adalah ubi Alabio ungu dengan cangkang kulit telur sebagai produk limbah utama industri makanan yang dijadikan filler untuk bahan campuran penyusun edible film. Kombinasi penggunaan cangkang kulit telur ini karena penggunaan tunggal pada edible film seperti pati masih kurang baikSelain itu, penambahan ekstrak kelakai bertujuan untuk meningkatkan aktivitas antioksidan edible film. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh penambahan filler pada edible film terhadap sifat fisik dan kimianya, serta penambahan bahan antioksidan untuk membuat edible film fungsional.Metode Penelitian yang akan digunakan untuk pengkajian dalam penelitian ini berupa studi literatur. Data yang diperoleh dikompilasi, dianalisis, dan disimpulkan sehingga mendapatkan kesimpulan mengenai studi literatur yang berkaitan dengan penelitian yang dilakukan. Hasil yang diperolah dari penelitian penambahan ekstrak kelakai dan filler cangkang telur ayam mendapatkan komposisi terbaik dari edible film yang dihasilkan dengan 10% tepung cangkang telur ayam dengan kandungan 5% ekstrak kelakai yang mempunyai ketebalan 0,174 mm, kuat tarik 1,5 MPa, panjang pemutusan 27,4%, transmisi uap air 10,83 g/m2 jam, scavenging activity 5,19% setelah 10 menit, uji biodegradasi bertahan sampai 5 hari dengan menggunakan media sosis. Karakteristik terbaik edible film pati ubi jalar diperoleh dari formulasi 10% (v/b pati) gliserol dengan ketebalan 0,06 mm, laju transmisi uap air 1,79 g/m2, elongasi 8,75% dan kekuatan tarik 0,75 Mpa. Edible Film yang dihasilkan dari penambahan kitosan akan menaikkan ketebalan film dan kuat tarik, namun menurunkan kelarutan, pemanjangan dan nilai laju transmisi uap air dari edible film yang terbentuk. Manfaat dari edible film fungsional ini dapat membantu memperpanjang umur simpan makanan dan ramah lingkungan.
