Judul: Pengayaan Spirulina dalam Formulasi Mi Sagu Kering.
Abstrak: Spirulina is a microalgae that contains of high protein, amino acids, and antioxidants, however the the product development is still limited. Meanwhile, diversification product of sago is very well known is sago noodle (mi gleser), however nutrition content of sago noodle was still inferior. The addition of Spirulina on the sago noodle is expected to increase the nutritional content. Addition of carrageenan serves to improve the texture of noodles that are not easily broken. The aim of this research was to create a diversification product made from local raw food commodities which were practical, nutritious, contain fiber and antioxidant by using sago enriched Spirulina. The selection of Spirulina concentration using organoleptic test, continued by analysis of chemical and physical of noodles, determining the best formula, and the determination of recommended dietary allowances. The results show that the most effective drying time is at temperatures 50 oC for 6 hours and the best consentration of carageenan was 0,2 %. Three of selected Spirulina concentrations namely 2,43 %, 4,85 %, and 12,14 %. The best formula is dried sago noodle with Spirulina 12,14 % with moisture 12,88 % wet weight, ash 1,14 % dw (dry weight), protein 5,06 % dw, fat 0,30 % dw, carbohydrates 93,53 % dw, fibre 3,05 %, IC50 antioxsidant 1440 ppm, and water activity 0,75. Water absorption 97,10 %, cooking loss 14,39 %, cooking time 17,58 minutes, hardness 379,60 gf, stickiness -26,50 gf, and springiness 0,76 gs. Nutrition information with serving size 80 grams has calories 203 kcal, 10 % daily value of protein, 0 % daily value of fat, 39% daily value of carbohydrate, and 15% daily value of fibre.

Judul: Formulation and Characteristics Determination of Dried Noodle from Porang Flour and Tapioca Starch with the addition of Spirulina platensis
Abstrak: Mi kering pada umumnya terbuat dari tepung terigu yang diperoleh dari hasil penggilingan biji gandum. Kebutuhan gandum di Indonesia dipenuhi melalui impor. Substitusi tepung porang dan tapioka sebagai sumber pangan lokal dengan penambahan spirulina dapat meningkatkan kandungan gizi dan senyawa bioaktif pada produk akhir mi kering. Penelitian ini bertujuan menentukan formula mi kering terbaik dari tepung porang dan tepung tapioka dengan penambahan Spirulina platensis melalui uji hedonik dan untuk menentukan karakteristik fisik, proksimat, dan fitokimia dari formula mi kering terpilih. Perlakuan yang digunakan dalam penelitian ini adalah penambahan konsentrasi spirulina sebanyak 1%, 2%, dan 3% ke dalam formulasi. Formula mi kering terpilih adalah penambahan konsentrasi spirulina 3% dengan nilai kadar air sebesar 10,56%, protein 1,95%, abu 0,63%, karbohidrat 83,29%, lemak 3,58%, serat pangan 19,93%, cooking loss 3,88%, daya rehidrasi 306,63%, elongasi 173,33%, dan nilai L* 35,99. Hasil uji fitokimia diperoleh mi kering spirulina terdeteksi mengandung alkaloid, flavonoid, dan fenol., Dry noodles are commonly prepared using wheat flour, obtained from milling wheat grain. Indonesia relies entirely on imports to meet its wheat demand. The substitution of konjac flour and tapioca as local food sources with the addition of spirulina can increase the nutritional content and bioactive compounds in the final dry noodle product. The aim of this study was to determine the best dry noodle formulation from konjac flour and tapioca flour with the addition of Spirulina platensis through hedonic tests and to determine the physical, proximate, and phytochemical characteristics of the selected dry noodle formulas. The treatment used in this study was the addition of 1%, 2%, and 3% spirulina concentrations into the formulation. The selected dry noodle formula is the addition of 3% spirulina concentration with a value of 10,56% moisture content, 1.95% protein, 0.63% ash, 83.29% carbohydrates, 3.58% fat, 19.93% dietary fiber, 3,88% cooking loss, 306,63% rehydration power, 173.33% elongation, and L* value 35,99. The results of the phytochemical test showed that spirulina dried noodles were detected to contain alkaloids, flavonoids, and phenols.
