Substitusi Tepung Buah Mangrove Bruguiera gymnorrhiza Pada Camilan Stick

Abstract

Bruguiera gymnorrhiza mangrove plant is one type of mangrove that can be used as a new food source, because this species contains high carbohydrates. The purpose of this study was to treat B. gymorrhiza mangroves into flour and processed into sticks. The study was divided into two stages, first treating B. gymorrhiza mangroves into flour including boiling, cutting, drying and grinding, secondly managing B. gymorrhiza mangrove flour into sticks including mixing ingredients, mixing dough, molding dough and frying. The first research was obtained yield of 27.96%, moisture content greater than SNI flour which was 14%, Total Plate Figures of 2.8x10³ colonies/gram, and pH 5.0. The second study carried out organoleptic tests with two mangrove flour treatments namely 50% B. gymorrhiza +50% Wheat flour and 25% B. gymorrhiza +75% Wheat flour, from 41 semi-trained panelists the average value included appearance by 54% (25% B. gymorrhiza +75% Wheat flour), color by 36% (25% B. gymorrhiza +75% Wheat flour), aroma by 54% (50% B. gymorrhiza +50% Wheat flour), taste by 57 % (50% B. gymorrhiza +50% Wheat flour), and 51% texture like sticks of B. gymorrhiza mangrove flour. It was concluded that this study fully fulfilled the requirements for the management of flour and sticks so that it could be produced as a new food substitute for wheat, the B. gymorrhiza mangrove fruit. 

Tanaman mangrove Bruguiera gymnorrhiza merupakan salah satu jenis mangrove yang dapat dimanfaatkan sebagai sumber pangan baru, karena spesies ini mengandung karbohidrat yang tinggi. Tujuan Penelitian ini untuk mengelolah buah mangrove B. gymorrhiza menjadi tepung dan diolah menjadi stick. Penelitian terbagi atas dua tahap, pertama mengelolah buah mangrove B. gymorrhiza menjadi tepung meliputi perebusan, pemotongan, pengeringan dan penggilingan, kedua mengelolah tepung buah mangrove B. gymorrhiza menjadi stick meliputi pencampuran bahan, pengadukan adonan, pencetakan adonan dan penggorengan. Penelitian pertama diperoleh Rendemen sebesar 27,96%, Kadar Air lebih besar dari SNI tepung yaitu 14%, Angka Lempeng Total sebesar 2,8x10³ koloni/gram, dan pH 5,0. Penelitian kedua dilakukan uji organoleptik dengan dua perlakuan tepung mangrove yaitu 50% B. gymorrhiza +50% Tepung terigu dan 25% B. gymorrhiza +75% Tepung terigu, dari 41 panelis semi terlatih nilai rataan meliputi kenampakan sebesar 54% (25% B. gymorrhiza +75%Tepung terigu) , warna sebesar 36% (25% B. gymorrhiza +75%Tepung terigu), aroma sebesar 54% (50% B. gymorrhiza +50%Tepung terigu), rasa sebesar 57% (50% B. gymorrhiza +50%Tepung terigu) ,dan tekstur  sebesar 51% menyukai stick dari tepung buah mangrove B. gymorrhiza. Disimpulkan penelitian ini sepunuhnya telah memenuhi syarat untuk pengelolaan tepung dan stick sehingga dapat diproduksi sebagai sumber pangan baru pegganti gandum yaitu buah mangrove B. gymorrhiza.
