Abstract

The purpose of this study was to determine the effect of wheat flour comparison with red bean sprout flour on the characteristics of lumpur cakes and to determine the ratio of wheat flour to red bean sprouts flour which can produce mud cakes with the best characteristics.This research used a Completely Randomized Design (CRD) with a comparison of flour and red bean sprouts as treatment. Treatment consisting of 6 levels (100%: 0%, 80%: 20%, 60%: 40%, 40%: 60%, 20%: 80%, and 0%: 100%). The experimentation was repeated 3 times So that it is obtain 18 experimental units. Observed variables of moisture content, ash content, protein content, fat content, crude fiber content, color, aroma, taste, texture, and overall acceptance of lumpur cakes. The data obtained were then analyzed by variants and if there was any effect on the treatment, then continued with Duncan test. The results showed that the addition of red bean sprout affected moisture content, ash content, protein content, fat content, crude fiber content, color, aroma, taste, texture, and overall acceptance of lumpur cakes. The best characteristic of lumpur cake substitution was 60% wheat flour and 40% red bean sprouts flour that produced moisture content of 35,62%, an ash content of 0,78%, protein content of 11,09%, a fat content of 36,67%, crude fiber content of 16,47%, regular color (normal), aroma (like), soft texture (like), taste (like), and overall acceptance (like).

Abstract

Penelitian yang dilakukan bertujuan untuk mengkaji aktivitas antimikroba ekstrak bubuk buah mengkudu (Morinda citrifolia L.) terhadap pertumbuhan beberapa bakteri patogen. Bubuk buah mengkudu diolah dari buah mentah dan matang yang kemudian diekstrak menggunakan berbagai jenis larutan pengekstrak. Larutan pengekstrak yang dicoba dalam penelitian ini adalah etanol, petroleum eter (PE), dan aquades. Hasil percobaan menunjukkan bahwa ekstrak bubuk mengkudu mentah dan matang yang diekstraksi dengan pelarut etanol memperlihatkan spektrum penghambatan yang lebih luas dibandingkan dengan menggunakan larutan pengekstrak PE dan aquades. Ekstrak buah mengkudu yang menggunakan etanol sebagai larutan pengekstrak dapat menghambat pertumbuhan Escherichia coli, Salmonella typhi dan Bacillus cereus. Sementara ekstrak menggunakan pelarut PE hanya memberikan penghambatan terhadap B. cereus, dan ekstrak bubuk mengkudu yang diekstrak dengan aquades tidak terdeteksi memberikan penghambatan terhadap ketiga bakteri uji.Kata Kunci: antimikroba, mengkudu, larutan pengekstrak, bakteri pathogen.

Abstract

Raw materials in the noodle processing vary widely, addition is made from flour, noodle can also be processed from tubers such as suweg. This study aims to apply the use of pregelatinized suweg flour with Moringa powder in the processing of noodles. Pregelatinized suweg flour is used as a substitution wheat flour by 50%. In addition to using pregelatinized suweg flour, Moringa leaf powder is applied as an additive to improve the nutritional value and appeal of a wet noodle. This study uses a randomized complete design with ratio pregelatinized suweg flour and moringa powder is 50: 0; 45: 5; 40:10; 35:15; 30:20. The parameters observed nutrient content and sensory properties of a noodle. Noodles with a ratio between pregelatinized suweg flour and Moringa powder 40: 10 have the best characteristics. The nutritional value of noodle is water content of 38.72%, ash content of 0.87%, 3.86% protein content, fat content 16.17% , and carbohydrate content 40.39%, and the color sensory criteria (rather like), aroma (rather like), texture (normal), taste (normal), and overall acceptance (normal).

Abstract

The objective of this study was to know the effect of angkak concentration and storage time on the characteristics of catfish sausage. This research used a Completely Randomized Design with two factors namely the concentration of the angkak (0 %, 1% and 2%) and the length of storage time (0, 7, 14, and 21 days). All of the treatments were repeated two times to obtain 24 units of experiments. The data obtained were analyzed by analysis of variance (ANOVA) and if the treatment had a significant effect, then it was followed by The Duncan Multiple Range Test. The results showed that the concentration of 2% with long storage 7 produce catfish sausage that is still feasible with the criteria: antioxidant capacity 252,80 mg GAEAC/ kg; brightness (L *) 31,03; redness (a *) 20,72; yellowish (b*) 18,81; moisture content 58,95; number of TBA 0,40 mg malonaldehyde / kg; the color slightly liked; flavor, textur, taste and overall acceptance neutral and color red and texture slightly chewy.
