Abstract

Penelitian ini bertujuan untuk mengetahui karakteristik fisikokimia (kadar air, kadar abu, kuat tarik, aktivitas air (aw), kadar serat pangan) dan karakteristik sensoris (warna, rasa, aroma, tekstur, overall) pada fruit leather nanas dan wortel dengan penambahan karagenan. Nanas berpotensi sioleah menjadi fruit leather, mempunyai aroma yang khas namun warnanya kuning pucat. Sehingga perlu ditambahkan wortel untuk memperbaiki warna produk. Permasalahan plastisitas sering muncul dalam fruit leather. Oleh karena itu perlu ditambahkan karagenan untuk memperbaiki tekstur dan memperkaya kandungan gizi fruit leather. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan satu faktor yaitu konsentrasi karagenan yang ditambahkan (0,3%, 0,6% dan 0,9%). Hasil penelitian menunjukkan bahwa terjadi peningkatan kadar abu dan kadar serat pangan dengan semakin tinggi konsentrasi karagenan yang ditambahkan pada fruit leather nanas dan wortel. Penambahan konsentrasi karagenan menyebabkan penurunan terhadap kadar air. Penambahan konsentrasi karagenan tidak memberikan pengaruh yang nyata terhadap aktivitas air. Penambahan karagenan pada fruit leather nanas dan wortel memberikan pengaruh yang nyata terhadap tekstur dan overall namun tidak memberikan pengaruh yang nyata terhadap warna, rasa dan aroma. Rekomendasi kosentrasi terbaik adalah 0,6% untuk fisikokimia dan sensoris.

Abstract

Kenteng Village Puntukrejo is one of the industrial centers ofprocessed sweet potato in Karanganyar Regency. Processed purple sweetpotato products produced include bakpia, wingko, and ice cream.Generally, the problems that occur in the sweet potatoes processing arethe equipment used is not in accordance with the standards for the foodindustry, the limited amount of equipment, hygiene and sanitation duringprocessing is not considered so as to bring the risk of contamination to theend product, as well as stagnant business conditions because the absenceof product diversification and limited marketing area. To solve theproblem through this program of dedication will be done (1) Introductionof appropriate technology for the processing of sweet potato; (2) Trainingof food industry management; (3) Introduction of processing technologyfor 'cassava leaf chips' as an effort to diversify products; (4) IT-basedmarketing training; (5) as well as facilitation of testing of nutrient contenton the end product. Through this dedication activity has been doneIntroduction of processing technology for 'cassava leaf chips' as the effortof product diversification. To improve product quality and productioncapacity has been given the equipment in the form of oven, large capacitymixer, wingko molding, freezer, analytical scales, stainless steel basin, andstainless steel table. Food industry management training in the form ofGood Manufacturing Practices (GMP) training has been given to ensurequality and safe the products. It also provides IT-based marketing trainingto improve product marketing. The results of laboratory analysis, purplesweet potato bakpia has water content 33.29%, mineral content 1.51%, fatcontent 11.91%, protein content 9.34%, carbohydrate content 43.95%, andantioxidant activity 6.20%. Purple sweet potato wingko has water content34.47%, mineral content 1.32%, fat content 11.70%, protein content 3.06%,and carbohydrate content 49.45%. While the cassava leaf chips has watercontent 5.39%, mineral content 5.23%, fat content 32.66%, protein content8.59%, and carbohydrate content 48.13%.Keywords: sweet potato, bakpia sweet potato, wingko sweet potato,cassava leaf chips, Ngargoyoso

Abstract

lactose, proteins and minerals. This study aims to determine the effect of variations in incubation time andsucrose concentration on the probiotic drink characteristics made from whey. This study uses CompletelyRandomized Design (CRD) with two factors, variation of incubation time (24 and 36 hours) and sucroseconcentration of (8%; 10%; 12%) on the probiotic whey drink. Probiotic starter cultures used are Lactobacillusacidophillus and Bifidobacterium longum IFO ATCC 13951 15 708 with ratio of 1: 1. Analysis was performedon viscosity, lactic acid levels, pH, antioxidant activity, total lactic acid bacteria and sensory characteristics.The results showed that the selected formula based on hedonic test is probiotic whey drink with 36-hourincubation time and 12% sucrose concentration. Probiotic whey drink has characteristics namely viscosity 6.578cP, 0.453% lactic acid levels, pH 4.36, the antioxidant activity of 19.409%, and total lactic acid bacteria 7.4 x109 cells / ml.
