Pemanfaatan Kulit Galam sebagai Bahan Baku Tambahan pada Pembutan Rak Telur pada PT. Prima Rezeki

Abstract

Gelam wood has the characteristics of a multilayered and peeling bark. Gelam bark that has these characteristics does not have a function and selling value, because the surrounding community only uses logs. Thus, the potential to be able to utilize the bark of gelam into a product that has a function and selling value. Utilization of gelam bark will be done with an experimental approach where the gelam bark will be used as an egg rack product for initial study of chemical component analysis. The purpose of this study is to design experiments on the use of galam skin as a mixture of egg rack making and saving the cost of making egg shelves with galam bark mixture. The method used is galam bark is divided into two parts, the inside and the outside are then analyzed chemical content and tested with Fourier Tranform InfraRed (FTIR). The results obtained are sequentially the highest chemical components of the galam skin, namely, extractive alcohol benzene 24.67% (exterior), lignin 48.18% (outer), and cellulose 36.21% (the inside Based on chemical analysis then the inner galam skin can be used as pulp and paper that does not prioritize brightness such as wrapping paper or as a mixture of egg rack making. The peak spectrum of FTIR wave numbers shows galam bark containing lignin and cellulose.
