Abstract

Edible film merupakan biopolimer yaitu polimer dari hasil pertanian yang digunakan sebagai bahan baku kemasan film tanpa dicampur dengan polimer sintetik (plastik) sehingga ramah lingkungan. Penggunaan edible film untuk kemasan produk pangan seperti sosis, buah dan sayuran bertujuan untuk memperlambat penurunan kualitas, karena edible film dapat berfungsi sebagai penghambat difusi gas oksigen dan karbondioksida, mencegah hilangnya kelembaban pada produk , mengontrol perpindahan padatan terlarut, sebagai Pengawet dan penguat rasa yang meningkatkan kualitas bahan makanan. Untuk membuat edible film dari pati batang kelapa sawit digunakan sorbitol. Sorbitol berfungsi sebagai plasticizer sehingga dapat meningkatkan elastisitas bahan, kekuatan tarik, kemuluran, ketebalan, dan mempengaruhi biodegradabilitas film. Variasi volume sorbital adalah 13,33; 15,99; 19.99; 26,66; 33,33 % (v/b). Hasil penambahan sorbitol pada pembuatan edible film dari batang kelapa sawit menghasilkan kuat tarik tertinggi sebesar 37,4375 Kgf/cm2 dan kuat tarik terendah sebesar 10,4736 Kgf/cm2. Rendemen WVTR edible film dari pati batang kelapa sawit adalah 0,9829. Hasil analisis SEM menunjukkan bahwa edible film dari pati batang kelapa sawit memiliki permukaan yang lebih halus, sedangkan edible film dari pati batang kelapa sawit memiliki permukaan yang kasar atau tidak homogen.

Abstract

Empowering housewives as members of society and still being classified as productive workers is very important, aimed at increasing awareness and independence in business, as well as expanding employment opportunities to increase family income in an effort to achieve a happy and prosperous family. In this regard, this can be done through various alternative activities, including training in making liquid detergent. Soap is a commodity that cannot be separated from household needs. It can be said that part of the routine expenses for housewives each month is allocated to purchasing washing soap. The methods used in this community service activity are socialization, discussion and practice or demonstration regarding raw materials, work procedures and calculation of production costs for making liquid detergent. The training participants are members of the Sumber Rezeki Cooperative in Sumber Mulyo Rejo Village with a total of 20 training participants. This activity was carried out in Sumber Mulyo Rejo Village, Binjai City on February 24 2024. The evaluation plan for service activities is that the target number of training participants is achieved, the training objectives are achieved well, the planned material targets are achieved and the participants are able to understand the training material. The result of this training activity in making liquid detergent is that members of the Sumber Rezeki cooperative in Binjai city have knowledge of making liquid detergent and provide innovation to improve the economy.
