Abstract

ABSTRAK. Kefir merupakan susu fermentasi yang belum banyak diminati oleh masyarakat karena rasanya yang asam sehingga perlu dilakukan pengembangan pada produk kefir. Salah satunya dengan penggunaan kefir sebagai bahan baku es krim yang diharapkan dapat meningkatkan minat masyarakat mengkonsumsi kefir. Karena rasanya yang asam, es krim kefir perlu ditambahkan pemanis yang dapat diperoleh dari buah buahan salah satunya adalah buah kurma (Phoenix dactylifera L). Buah kurma adalah buah yang memiliki kandungan gula yang cukup tinggi dan memiliki potensi untuk dimanfaatkan sebagai pemanis alami. Penelitian ini bertujuan untuk mengetahui pengaruh substitusi gula dengan puree buah kurma pada beberapa konsentrasi terhadap kadar gula, total padatan, total asam, total khamir, total BAL, total mikroba dan hedonik dari es krim kefir. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan puree buah kurma sebagai pemanis pada beberapa level yaitu 0%, 25%, 50%, 75% dan 100%. Hasil penelitian menunjukkan bahwa substitusi gula dengan puree buah kurma berpengaruh nyata (p0,05) terhadap kadar gula, total padatan, total asam es krim kefir, tetapi tidak memberikan pengaruh yang nyata (p0,05) terhadap total khamir, total BAL dan total mikroba. Substitusi gula dengan puree buah kurma memberikan pengaruh nyata terhadap tingkat kesukaan rasa, warna, tekstur dan overall kesukaan es krim kefir, namun tidak terdapat pengaruh yang nyata terhadap aroma es krim kefir.(Effect of sugar substitution with dates puree (Phoenix dactylifera L.) on the chemical, microbiological and hedonic properties of kefir ice cream) ABSTRACT. Kefir is a fermented milk that has not been in a great demand by people because of its sour taste, so it is necessary to develop kefir products. The use of kefir as a raw material for ice cream is expected to increase peoples interest to consume kefir. Because of its sour taste, kefir ice cream needs to be added with sweeteners which can be obtained from fruits, one of which is dates (Phoenix dactylifera L). Dates are a fruit that has a high enough sugar content and has the potential to be used as a natural sweetener. The purpose of this study was to determine the effect of sugar substitution with date palm puree with several concentrations on the value of sugar content, total solid, total acid, total yeast, total LAB, total microbes and hedonic from kefir ice cream. This study used a Completely Randomized Design (CRD) with dates puree as a sweetener at the level of 0%, 25%, 50%, 75% and 100%. The results showed that the substitution of sugar with date palm puree had a significant effect (p0,05) on the sugar content, total solid, total acid of kefir ice cream, but did not have a significant effect (p0,05) on the total yeast, total LAB dan total microbes. Substitution of sugar with dates puree had a significant effect on the taste, color, texture and overall preference and there was no significant effect on the aroma of kefir ice cream.

Abstract

Red ginger (Zingiber officinale Rosc.) is a commonly utilized spice plant in blends and marinades. The research was conducted to determine the effect of different red ginger blend concentrations on fat levels, protein levels, antioxidant activity, and hedonic quality of dried beef. The research used a Randomized Block Design and descriptive analysis. Treatments were differentiated by adding different concentrations of red ginger blend (P0 = 0%, P1 = 5%, P2 = 10%, P3 = 15%, and P4 = 20%). The addition of a 15% red ginger blend is the best treatment for the chemical properties of dried beef, while the addition of a 5% red ginger blend is the best treatment for the hedonic properties of dried beef.

Abstract

This study aims to determine the effect of varying concentrations of butterfly pea flower extract (Clitoria ternatea) on kefir water in terms of total dissolved solids (TDS), total acidity, yeast count, and organoleptic properties. The materials used were dried butterfly pea flowers dissolved in mineral water (extract) and ingredients for producing kefir water. The experiment was conducted using a Completely Randomized Design (CRD) with extract concentrations of 0%, 0.5%, 1.0%, and 1.5% (v/v), each repeated five times. Data were analyzed using Analysis of Variance (ANOVA) and followed by Duncan's Multiple Range Test (DMRT) for the parameters of total dissolved solids, acidity, and yeast count. Organoleptic tests were analyzed using the non-parametric Kruskal-Wallis test, and if significant differences were found, they were followed by the Mann-Whitney test. The results of the study showed that the addition of butterfly pea flower extract at different concentration variations significantly affected (p<0.05) total dissolved solids, total acidity, and total yeast, with average values of total dissolved solids ranging from 10.90 to 10.40°Brix, total acidity from 0.05 to 0.21%, and total yeast of 1.60×10⁶ CFU/ml to 1.30×10⁶ CFU/ml. However, it did not affect taste, aroma, and texture, although color showed significant differences (p<0.05). Organoleptic test results yielded taste scores of 2.72 - 2.84, color scores of 1.44 - 4.88, aroma scores of 2.36 - 2.92, and texture scores of 2.04 - 2.36. However, the addition of butterfly pea flower extract at varying concentrations tended to reduce total soluble solids while increasing yeast count, total acidity, and enhancing color attributes in sensory evaluation.

Abstract

This research aims to determine the influence of work ability and work motivation on the productivity of workers with disabilities at PT. Wangta Agung. As a form of inclusion and equal employment opportunities, PT Wangta Agung employs workers with disabilities who are usually not considered enough and do not get the same opportunities as other workers. Data analysis was carried out using multiple line regression. Based on research, it can be concluded that work ability and work motivation simultaneously have a positive and significant effect on the productivity of workers with disabilities at PT. Wangta Agung. Likewise, partial testing shows that both work ability and work motivation have a significant influence on the productivity of workers with disabilities at PT. Wangta Agung. Based on this, companies need to consider improving the work ability of their workforce and motivating them so that it has a positive impact on increasing productivity in order to achieve company goals.

Abstract

This research aims to improve the diversity of functional foods rich in bioactive peptide components and have a unique flavor for black soybean miso through the addition of crude bromelain and Lactobacillus plantarum. This research uses a completely randomized design with 5 treatments and 4 repetitions to obtain a total of 20 experimental units. The treatments are the different concentrations of crude bromelain addition, namely the control treatment or 0% (T0), 3% (T1), 6% (T2), 9% (T3), and 12 % (T4). The parameters observed are water content, water activity, pH value, and lactic acid bacteria (LAB) viability. The result showed that an increase in the crude bromelain concentration may increase the water content and water activity of the black soybean miso, while the pH value decreases. Based on the viability of the LAB showed a wavering result. Miso with the 9% concentration of crude bromelain is the best result among the others.
