Abstract

The proposed mathematical model aims to optimize the amount of demand based on the uncertainty of salt supply to meet the needs of salt in society. This study uses an econometric approach to model the supply and demand for salt based on the uncertainty of the amount of supply. The research results are the salt productivity model used to build a salt availability model. Meanwhile, the salt demand model is built based on past data about the number of requests for each period. The demand and supply functions for salt use a two-variable linear equation system. The salt field productivity models follow a quadratic polynomial pattern according to the difference in seasons at each time. The demand and supply of salt model follows a linear regression. The supply of salt in Indonesia is uncertain at any time. But, the demand for salt increased at the time. It is necessary to model the demand and supply of salt to meet the demand for salt

Abstract

Moringa leaves are still utilized in a limited number of processed food items. Moringa is mostly used as a vegetable. Moringa leaves contain enzymes that produce disagreeable scents; thus, their utilization requires product innovation. Nuggets are processed meats that are simple to prepare due to their inclusion in frozen foods that can be readily prepared and kept, but the hue is often unappealing. Fortification is one of the processes that involves adding nutrients to a food product so that it has nutritional value. sufficient. The inclusion of antioxidants produced from Moringa leaves in this nugget product provides nutrition. This study aims to determine the effects of increasing the concentration of moringa leaves on the quality of chicken nuggets as well as the interaction between the usage of concentration and treatment of moringa leaves on the quality of chicken nuggets. The research design used was a factorial randomized block design (RAK) with two treatment factors. Factor 1 was added Moringa leaves which consisted of 3 levels (fresh Moringa leaves, dried Moringa leaves, blanching Moringa leaves), and factor 2 was the concentration of Moringa leaves, which consisted of 3 levels (10%, 15%, 20%). The parameters of the tests were water, ash, texture, fat, protein, chlorophyll, and antioxidants. The best treatment was on 20% fresh leaf treatment which had 63.24% water content, 7.33% ash content, 0.36% chlorophyll, 55.66% antioxidant, 6.07% fat, 12.05% protein. Moringa nuggets are a potential outcome of Moringa leaf innovation.

Abstract

Kombucha is a renowned fermented drink for its diverse health benefits. This research aims to evaluate sweetened red ginger extract as an alternative substrate in making kombucha by observing the chemical properties (pH, total acid, total sugar, total polyphenol, chemical compound profile using LC-MS/MS) and the antioxidant activity. Three variables were varied, i.e., red ginger concentration (1, 5, and 10%), kombucha culture concentration (10 and 20%), and fermentation time (0, 6, and 12 days). The total sugar and pH declined during fermentation while the titratable acidity, polyphenol, and antioxidant activity increased. The kombucha prepared with 20% culture concentration resulted in a greater reduction of pH and increase of titratable acidity, total polyphenol, and antioxidant activity than the one prepared with 10% culture concentration. The red ginger kombucha prepared with 10% ginger and 20% culture in 12 days displayed the highest antioxidant activity. It revealed ten active compounds under the LC-MS/MS investigation, i.e., 3’,4’,5’,5,7,8-hexame-thoxy flavone, 6-gingerol, evodin, isosakuranetin-7-rutinoside, methyl ophiopogonanone A, narirutin, neohesperidin, ononin, sinensetin, and shogaol. This research shows that red ginger extract fermentation using kombucha culture can be an alternative technology to produce red ginger-based functional drinks with healthy organic acids, healthy polyphenols, and antioxidant activity.

Ginger coffee effervescent tablets will be an alternative product to increase coffee consumption, and the industry can apply. This research aimed to study the sensory profile of ginger coffee effervescent tablets and their solutions made from a different concentrations of ginger coffee powder and types of organic acids. This study used a factorial design with two factors. The first factor was the concentration of 30 % and 50 % of ginger coffee powder. The second factor was the type of organic acid which consists of tartaric acid, malic acid, and a combination of both acids. A descriptive sensory test was conducted by using trained panelists. The results showed that the increasing concentration of ginger coffee powder in the formulation had a significant effect on the sensory profile of the ginger coffee tablet and effervescent solution, especially the darker and browner colors. In contrast, the taste and aroma weren’t changed significantly. The difference in organic acids in the formulation did not cause significant differences in the sensory profile of the ginger coffee effervescent solution and tablets. In general, the dissolution of tablets in water into an effervescent solution will increase the color sensory profile but not the aroma profile.

Abstract

Suweg (Amorphophallus campanulatus) is a tuber that has not to explored widely for its use. This study aimed to determine the effect of physical modification of UV-C and HMT on the characteristics of suweg flour. This study used a factorial design with two factors. The first factor is the type of modification which consists of Ultraviolet-C Irradiation (UV-C) and Heat Moisture Treatment (HMT). The second factor is the length of modification time. The UV-C modification uses 10 min, 20 min, and 30 min. Simultaneously, the HMT modification uses four, five, and six hours. The control used unmodified suweg flour. The result showed that the modified UV-C and HMT methods with different time-process variations affect the suweg flour characteristics. UV-C and HMT modification was increased solubility and yellowness (b*). In contrast, it decreased yield, moisture content, lightness (L*), and redness (a*). HMT modification had a most significant effect than UV-C modification in suweg flour modification.

Abstract

Nata is a source of fermented food that contains high fiber. However, to reduce the use of ZA in food, other natural nitrogen sources are needed so that they are safer in the body. This study aims to determine the potential of telang flower or butterfly pea (Clitoria ternatea) extract as a substitute for ZA in fermented fiber-rich foods such as nata de banana peel. The research method was carried out by experimental methods, namely the observation of yield, fiber content, and thickness of  nata de banana peel without the addition of ZA (X1) and with the addition of ZA (X2) with the addition of a concentration of 25 ml and 50 ml of telang flower.The result showed that the highest nata result in terms of yield, fiber content, and nata thickness were nata samples with 50 ml of telang flower extract with the addition of ZA. The sample with telang flower extract without the addition of ZA was the highest in terms of yield and fiber content was nata with 25 ml of telang flower extract. Based on the thickness, nata with 25 ml of telang flower extract without the addition of ZA had a greater thickness than nata with 50 ml of telang flower extract without the addition of ZA. This shows that the sample with the extract of telang flower without the addition of ZA can form nata de banana peel. Therefore, the extract of telang flower can be used as a substitute for ZA in the fermentation process of nata by Acetobacter xylinum. Based on the fiber content produced, the best nata is nata de banana peel which is formed from samples with 25 ml of telang flower extract without the addition of ZA
