Abstract

Jahe merah yang banyak digunakan sebagai rempah-rempah pada makanan, mengandung senyawa-senyawa yang bersifat antioksidan. Pada penelitian ini melakukan ekstraksi antiosidan jahe merah menggunakan pelarut etil asetat dengan cara maserasi digesti. Ekstrak dengan konsentrasi masing-masing 0; 0,05; 0,1 dan 0,15% ditambahkan ke minyak kacang tanah dan diinkubasi menggunakan inkubator pada suhu 60℃ selama 72 jam. Analisis oksidasi dilakukan selama 72 jam, setiap 24 jam dan dimulai dari 0 jam. Hasil penelitian menunjukan penggunaan ekstrak etil asetat jahe merah untuk setiap konsentrasi memberi pengaruh yang signifikan dalam menghambat oksidasi minyak kacang mulai inkubasi 24 jam. Ekstrak Jahe dengan konsentrasi 0,15% memberi pengaruh yang paling nyata sampai inkubasi 72 jam.

Abstract

The objective of the study was to develop the cellulose Nata/dietary fiber production from coconut water using bacterium, Acetobacter xylinum, as health product containing natural fibers. The study used Complete Randomized Design with treatments of different concentration of inoculum Acetobacter xylinum, each of which had 3 replications. The treatments were liquid inoculum of Acetobacter xylinum: A = 5 %/1000 ml (5 % of liquid inocula were added into 1000 ml of coconut water), B = 7.5 %/1000 ml (7.5 % of liquid inocula were added into 1000 ml of coconut water), C = 10 %/1000 ml (10 % of liquid inocula were added into 1000 ml of coconut water), D = 12.5 %/1000 ml (12.5 % of liquid inocula were added into 1000 ml of coconut water), and E = 15 %/1000 ml (15 % of liquid inocula were added into 1000 ml of coconut water). This study concluded that 1) the liquid inocula of Acetobacter xylinum could result in cellulose nata; 2) the highest quality of the cellulose nata/dietary fiber from the use of liquid inocula of Acetobacter xylinum) was found in treatment E for pellicle weight, 1009.3 gr, layer thickness, 1.50 cm, rendement, 90.82 %, and water content, 79.71 %, and fiber level, 1.31 %, for treatment D and E, respectively.

Abstract

Agricultural development over the past decade, is more identical tocommodity development, which focuses on meeting domestic food needs.The development of globalization, a country in this case the government,must be able to facilitate and encourage the community to developproductive activities, including developing the creative food industry,which is characterized not only by fulfilling quantity, quality, but havingselling value, or the value of excellence product specifics (prepositionvalue), and provide economic (added value). The synergy of various parties(stake holders) encourages increased production of creative food productsby intensifying : technology, information, ideas and creativity as well asskills that emerge from the community, both individual farmers andindustrial groups in the South Minahasa Regency.The objectives of this study are: 1. Identify the types and characteristicsof coconut-based food industries in South Minahasa regency and 2.Calculate the economic added value of the development of coconut-basedfood industries in South Minahasa regency. 3. Obtain appropriate methods,strategies and models for the development of a food industry based oncoconut in South Minahasa Regency. This study uses several methods,namely: descriptive method, calculation of added value according to Costerand Schaffer, 1982) and the SWOT method for obtaining methods,strategies and models for the development of creative food industries thatare suitable in South Minahasa regency. The results showed that there were3 types of development of creative food industries made from coconutwhich already existed in South Minahasa Regency, namely: 1. culinary, 2.medicines 4. research development. From this type of creative foodindustry, it has provided real economic added value for farmers, industrialgroups and macro for the economic growth of the community, whenapplying methods, strategies and models that match the potential andcharacteristics in South Minahasa Regency.Keywords: development, creative food industry, coconut raw materials

Abstract

Antioxidants are compounds that can counteract the negativeeffects of free radicals in the body. Binahong leaves (Anredera cordifolia(Ten.) Steenis) contain steroids, alkaloids, flavonoids, saponins,polyphenols and tannins which can potentially have antioxidant capacity.Binahong leaf tea is an herbal tea produced from fresh binahong leaveswhich has antioxidant content. The purpose of this study was to determinethe antioxidant activity at the varied immertion temperature. This studyused a descriptive method at variations in immertion temperatures of60⁰C, 80⁰C and 100⁰C for 5 minutes. Antioxidant activity test was carriedout on DPPH, total flavonoids and total Phenol. The highest DPPHscavenging activity obtained at 100⁰C was 62.15% with total flavonoidsand total phenolic were 120 mg / 100g and 327.75 mg / 100g, respectively.Keywords: Binahong Leaf Tea, Antioxidant Activity

ABSTRACTModern community life makes the need for fast food increases. One of the fast foods that is often consumed is cereal and beans. This research was conducted to produce snack bars that are healthy and rich in fiber. This study uses a completely randomized design (CRD) research method with the treatment of coconut pulp and yellow sweet potato flour, each treatment is carried out with 3 replications. The parameters tested were chemical properties (water content, ash content, protein content, fat content, carbohydrate, crude fiber, and antioxidant activity), physical properties (hardness test), and sensory properties (color, taste, scent, and texture).Based on the organoleptic test results of snack bars the panelists preferred were treatment C (50% coconut pulp flour : 50% yellow sweet potato flour) with moisture content of 28.28%, ash content of 1.60%, protein content of 7.74%, content of fat 14.27%, carbohydrates 48.11%, crude fiber 12.51%, antioxidant activity 49.64 ppm, and in terms of physical properties the hardness level is 80.55 mm/g/sec. Keywords : Snack Bars , Coconut Pulp Flour, Yellow Yam Flour ABSTRAKKehidupan masyarakat yang modern membuat kebutuhan makanan siap saji semakin meningkat.
