  Abstract:

  The purpose of this study was to determine the effect of adding tofu dregs flour on the protein content of steamed batik cake and how the public's acceptance of steamed batik cake with the addition of tofu pulp flour. The purpose of this study was to determine the effect of adding tofu dregs flour on the protein content of steamed batik cake and how the public's acceptance of steamed batik cake with the addition of tofu dregs flour. This research was conducted using a quantitative experimental method with a single factor completely randomized design (CRD), namely the ratio of the addition of tofu dregs flour: wheat flour with a concentration (0%: 100%), (35%: 65%), (40%: 60%) , and (45% : 55%). The parameters measured were the protein content of the steamed batik cake and the acceptability or liking for the texture, color, aroma, taste, and overall of the steamed batik cake. The protein content test used the Kjeldahl method, while the acceptability used the hedonic test (preference). The data was processed using the one way ANOVA test, and if it had a significant effect, it was continued on the Duncan follow-up test. The results showed that the addition of tofu dregs flour in steamed batik cake had a significant effect on the protein content of the sponge. The highest protein content of steamed batik cake was P3 with a value of 9.088%, while the lowest protein content was found in the P0 treatment without the addition of tofu dregs flour. The acceptability of steamed batik sponge cake with the addition of tofu dregs flour shows that the taste, texture, color, and overall have a significant effect. While the aroma has no significant effect. The highest acceptance of taste was found in P1 (7,000) with the criteria of liking, the highest acceptance of aroma was P2 (6.0167) with the criteria of somewhat liking, the highest texture acceptance of P0 (7.2667) with the criteria of liking, the acceptance of color (6,500) with the criteria are rather like, the highest overall acceptance is P1 (6.5167) with the criteria being somewhat like close to like. The pH of the tofu dregs flour is 6.68, indicating the pH of the dregs flour is slightly acidic. The need for further tests on the nutritional content in more depth in steamed batik cakes.

  Abstract:

  This study aims to evaluate the sensori, pH, sugar content, and melting properties of ice cream made from a mixture of corn and moringa leaves with the addition of alginate stabilizer, CMC, and gelatin. This study used a completely randomized design (CRD) in one direction, where the main factor was the type of stabilizer (alginate, carboxymethylcellulose, and gelatin). The parameters of this study were pH, sugar content, melting, and organoleptic. The gelatin stabilizer increased the pH of the ice cream but was lower than the alginate stabilizer, which showed a significant difference. The addition of a CMC stabilizer increases the sugar content of ice cream significantly. Although the use of CMC or gelatin stabilizer was not significant in reducing the melting of ice cream, the use of alginate stabilizer gave the best texture, followed by no stabilizer, CMC, and gelatin. There are significant differences in the texture and color of ice cream, but no significant differences in aroma or taste. In conclusion, the use of alginate stabilizer affected the texture and color of Moringa corn ice cream, while the aroma and taste were not significantly affected.

Soursop leaves with the Latin name Annona muricata L. actually contain many benefits for herbal medicine ingredients, and to maintain body condition. Results of Antioxidant Test Analysis The highest antioxidant content was in treatment A, namely purslane 7 gr and soursop leaves 3 gr. With a drying temperature of 150oC that is equal to 17.765%. The antioxidant value in treatment A came from the concentration of purslane exposed to quite a lot of soursop leaf formulation. In contrast, in treatment D, purslane 8.5gr: 1.5gr soursop leaves at 150oC had a low antioxidant content because the concentration of purslane was exposed to quite a bit of the soursop formulation. The effect of organoleptic tests on purslane and soursop leaf formulations in the manufacture of herbal teas, which was tested by 50 panelists with 4 parameters from 4 treatments that were accepted and preferred, referred to treatment D (8.5 g purslane formulation: 1.5 g soursop leaf with 1500C).

  Abstract:

  Duck (Cairina moschata) is a type of domestic poultry which has a significant role as a meat-producing poultry. Pineapple contains a proteolytic enzyme called bromelain, which is used to tenderize meat. Soaking time is also known as marinating time. The principle of marinating meat is soaking it in a marinade (solution or sauce) containing certain ingredients so that passive transport of the marinade into the meat by osmosis occurs slowly. This study aims to obtain the optimum dose in the long process of soaking pineapple fruit extract on the physical and sensory properties of wild duck meat. This study used an experimental method with a completely randomized design (CRD) treatment used as many as 5 treatments, namely soaking pineapple extract at a dose of 35 ml in 100 g of wild duck meat which was soaked for (P0 = no soaking, P1 = 15 minutes, P2 = 30 minutes, P3 = 45 minutes and P4 = 60 minutes). The treatment was repeated 4 times. The data obtained were analyzed using the ANOVA test (analysis of variance). Differences between treatments were tested further with Duncan's test. The results showed that immersing the pineapple extract solution on the wild duck meat had a significant effect (P<0.05) on the pH, color, texture and preferences of the duck meat. However, immersion in pineapple extract solution had no significant effect (P>0.05) on cooking loss, aroma and taste of wild duck meat.

  Abstract:

  Honey pineapple (Ananas comosus L Merr) is one of the typical Pemalang fruits which is very popular because it contains lots of vitamins C and A which act as antioxidants in the body. But pineapple has a texture that is susceptible to physical, chemical and biological damage. This research aims to determine the effect of adding carrageenan concentration on the organoleptic properties and vitamin C levels in honey pineapple jam. Honey pineapple (Ananas comosus L Merr) was used as the main ingredient with the addition of carrageenan at concentrations of 0%, 0.2%, 0.6% and 1%. The method used was the Completely Randomized Design (CRD) method with one factor (addition of carrageenan) and three replications. The observation data was processed using SPSS 24 software with the One Away ANOVA test of variance. If there were significant differences between treatments, the Duncan Multiple Range Test (DMRT) was carried out at a significance level of α 0.05. In the organoleptic test, the parameters tested include color, aroma, taste, texture and preference parameters. Apart from that, vitamin C levels are also tested using iodometric titration or direct titration. The results showed that the addition of carrageenan had a real influence on organoleptic tests (color, taste, aroma and texture), but did not have a real influence on organoleptic tests of preference parameters. On vitamin C levels, the addition of carrageenan also has a real effect. With the highest average in treatment K1 (0%) with a value of 0.56% and the lowest average in treatment K4 (1%) with a value of 0.18%.

  Abstract:

  Tempe adalah produk olahan nabati yang terbuat dari bahan dasar kacang- kacangan. Tempe memiliki tekstur yang lebih lunak daripada kedelai, karena kapang tempe mencernakan matriks diantara sel-sel biji kedelai, sehingga sel terlepas dari bahan-bahan di sekitarnya. Upaya untuk meningkatkan sifat fungsional tempe dengan penambahan ekstrak daun kelor (Moringa Oliefera) yang dilakukan pada penelitian ini. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan ekstrak daun kelor terhadap mutu organoleptik dan kandungan vitamin C pada tempe. Metode ini yang digunakan adalah metode eksperimen dengan rancangan acak lengkap (RAL) dengan 6 perlakuan dan masing-masing diulang empat kali. Perlakuan yang dilakukan adalah penambahan ekstrak daun kelor sebesar 0%, 1%, 2%, 3%, 4%, dan 5%. Analisis yang di lakukan adalah kandungan vitamin C dan uji organoleptik. Hasil dari penelitian ini menunjukkan bahwa penambahan ekstrak daun kelor memiliki pengaruh yang signifikan terhadap kandungan Vitamin C dan organoleptik pada tempe. Tempe dengan penambahan ekstrak daun kelor 2% yaitu pada sampel C dengan warna memiliki nilai sebesar 3,87, untuk nilai aroma sebesar 3,8, tekstur sebesar 4,13, dan rasa sebesar 4,2. Sedangkan, kandungan Vitamin C tertinggi diperoleh dari sampel F dengan kandungan tepung daun kelor paling tinggi yaitu 5% dengan rata-rata 606,84 mg/100g.

  Abstract:

  Yogurt is the result of the coagulation process of milk in the fermentation process of lactic acid bacteria through the activity of lactic acid bacteria (BAL) Lactobacillus bulgaricus and Streptococcus thermophilus which produce a semi-thick texture with a sour taste. This fermentation process causes the pH level of milk to drop, thus extending shelf life and preventing the growth of pathogenic bacteria such as. Soy milk is the result of soy protein extraction with several processes including soaking, crushing, filtering, and boiling. One of the antioxidants contained in soy milk is isoflavones that function to ward off free radicals. The study used a completely randomized design (CRD) with 6 treatments with 4 repetitions, namely S1 (1%), S2 (1.5%), S3 (2%), S4 (2.5%), S5 (3%), S6 (3.5%). The results of the data will use the SPSS statistical analysis with the one way ANOVA test method and if there is a significant effect on each treatment it will be continued with the Duncans advanced test (DMRT) at the 5% level. The level of starter has a significant effect on the organoleptic properties of soy milk yogurt in terms of taste, color and appearance. Based on the sample test, the best concentration was obtained in sample S1 with 1% starter content. For the pH acidity level test, the best results were obtained in sample S2 with a starter content of 1.5%, however, the pH value of sample S2 was supported by sample S1 so that it showed relatively small results, and in the sugar content test, the best results were obtained in sample S1 with starter content 1%.
