Abstract

Pada ekosistem air, mikroalga merupakan penghasil alami energi dan senyawa metabolit potensial. Mikroalga ekstraseluler memiliki fungsi sebagai penghambat dan memicu pertumbuhan senyawa. Tetraselmis chuii memiliki komponen bioaktif seperti asam lemak dan ester yang digunakan sebagai agen antibakteri. Antimikroba adalah senyawa yang dapat menghambat pertumbuhan mikroba. Proses ekstraksi dipengaruhi oleh metode ekstraksi, berbagai pelarut, dan kondisi ekstraksi. Tujuan penelitian ini adalah untuk mendapatkan informasi tentang penggunaan berbagai pelarut dan ekstraksi siklus total terhadap hasil ekstrak Tetraselmis chuii, mengetahui aktivitas antimikroba ekstrak Tetraselmis chuii terhadap S. aureus, E. coli, A. flavus dan C. Albicans, dan mengidentifikasi senyawa bioaktif ekstrak Tetraselmis chuii yang bertindak sebagai agen antimikroba dengan menggunakan metode GC-MS. Hasil penelitian menunjukkan bahwa rendemen tertinggi dihasilkan dari pelarut aseton pada 3 siklus ekstraksi, yaitu sebesar 35.19%. Uji aktivitas antimikroba terbaik menghasilkan ekstrak dari pelarut kloroform dengan ekstraksi 3 siklus dengan diameter zona hambatan 16.43 mm pada S.aureus, 16.07 mm pada E. coli, 15.46 mm di C. albicans, dan 15.8 mm di A.flavus. Senyawa bioaktif dari ekstrak Tetraselmis chuii berpotensi sebagai senyawa antimikroba, termasuk asam lemak, ester, alkohol, keton, benzene, dan alkana.

Abstract

Oil palm empty fruit bunches (OPEFB) are solid waste from the palm industry that contains linocellulose in the form of lignin, cellulose and hemicellulose. Lignin using as a binder, adhesive, filler, surfactant, polymer product, dispersant and source of ingredients. The method of isolating lignin can be done by the organosolv method. In the organosolv process, temperature is a factor that will affect the speed of the lignin dissolution reaction. This study aims to determine the physical characteristics of oil palm empty fruit bunches of PT. Tunggal Perkasa Plantations, Regency of Indragiri Hulu, Riau Province. In the study conducted effect of cooking temperature on the isolation process of OPEFB with the organosolv method using acetic acid solvents with 0.1% HCl catalyst. The experimental design used in this study was a Completely Randomized Design consisting of 4 treatments  temperature of  cooking  (60°C,  85°C,  100°C  and  121°C).  L value indicates the brightness of lignin, the higher the L value means that the color of lignin is brighter. The value of Lignin at  100 ̊C was  35.14 while the value of L lignin at 121 C  was  32.245. If  ‘a’ values indicate lignin redness and  ‘b’ values indicate yellowish. The highest yield of OPEFB lignin was obtained using a temperature of 85 °C is 15.87%.

Abstract

Canna tuber (Canna discolour L.) is a source of carbohydrates and resistant starch (RS) related to its starch phosphate and amylose content. Meanwhile, seaweed (Eucheuma spinosum) is a type of hydrocolloid high in dietary fibre. This study aims to see the acceptability based on the results of organoleptic test and to evaluate the nutritional profile of lasagna made from canna tuber flour and seaweed flour. The raw materials used are canna tuber flour and seaweed flour with a ratio 60:40; 70:30; and 80:20 (w/w). The nutritional aspects observed included the levels of protein, fat, water, ash and dietary fibre. The result of the analysis showed that lasagna with a ratio of canna tuber flour: seaweed flour 70:30 (w/w) has the most favourable organoleptic properties. The result of the analysis of nutritional aspects of the sample also showed a significant increase in dietary fibre content (15.36%), ash content (1.25%), and lower fat content (0.16%) compared to commercial lasagna. Based on the result of this study, it can be concluded that canna tuber flour and seaweed flour have a potential as raw materials for lasagna production with favourable organoleptic properties and high dietary fibre content.
