Abstract

Kue Dadar (lit. pancake) is a green-coloured Indonesian cake, but in recent years it saw the colouring of the pancake is mainly using synthetic colouring. This type of colouring can be substituted with natural colourings such as Betalain, gathered from the skin of the red dragon fruit. The skin is also beneficial for human because it also contains fibre, pectin, and other nutritious contents. This research aims to obtain the formulation of red dragon skin pancake, using the factors of red dragon skin?s amount (X1), egg?s amount (X2), and thick coconut milk?s amount (X3). This research will be conducted through experiments, utilising Response Surface Methodology (RSM) and Central Composite Design (CCD). Data analysis will be assisted by Software Design Expert ver. 7.1. The results of this pancake formulation?s optimisation are 89.73 grams of red dragon fruit skin, 39.99 grams of egg, 167.78 ml of thick coconut milk and have a quadratic characteristic. Analysis results of R2 and Adjusted R2 by colour and texture response are 0.8720; 0.9500 and 0.9327; 0.9049 respectively. Response values on its optimal condition are 5.47 for colour and 5.62 for texture. Other quality values are 5.00 for shape (good shape), 5.23 for aroma (good smell), and 4.90 (sweet flavour).

Abstract

Virgin Coconut Oil (VCO) is an oil product derived from coconut without experiencing high-temperature processes and chemical adding. The making of VCO can be done by various methods. One of them is using an enzymatic method that can be combined with fermentation techniques. The purpose of this study was to identify the physical character and chemical properties of the product from a combination of fermentation and enzymatic by using the bromelain enzyme derived from pineapples extract. The fermentation is carried out for 20 hours. The results showed that pineapples extract showed that bromelain enzyme showed by the colour change of pineapples extract to be brown and there were black sediment, the pH average of pineapples extract was 3.6, the highest VCO in the additional treatment was 50% pineapples extract to 70 ml and the lowest at pineapples extract 20% by 52 ml. The general, the flavour and colour are neutral, there was still the distinctive of pineapples. The highest moisture content in VCO oil is 0.36% in addition to pineapples extract 40% and the lowest is 0.14% from the addition of 30% pineapples extract. While the highest FFA level was at the addition of 20% pineapples extract concentration with FFA value of 0.36%, while the addition of 50% pineapples extract which produced FFA content was 0.32%. The results of the study concluded that the VCO produced was good, but the physical characteristics of the aroma did not meet the requirements.

Abstract

Pineapple is one of perishable horticultural commodities that usually consumed in fresh form. Based on that, commercial food processing technology are required to extend shelf life of product. Shelf life product information is necessary before product launched in the market to ensure and guarantee the customers. The object of this research was to determine shelf life of pineapple juice that estimated by using ESS (Extended Storage Studies) method. Pineapple juice with preservative (0.05% sodium benzoate) and no preservative was processed, packaged and stored at chilling temperature (7°C) and room temperature (25°C). The juices were analyzed for the sensory attributes such as, taste, aroma, appearance, and viscosity. Sensory test was stopped when the panelist refused to do test for bubble, foam and mold growth on the surface, fermentation aroma appeared, and viscosity of pineapple juice increased. The shelf life were estimated to be 14 week for pineapple juice stored at 7°C with preservative (T1B1), 10 week for pineapple juice stored at 7°C without preservative (T1B2), 2 week for pineapple juice stored at 25°C with preservative (T2B1)and less than 2 week for pineapple juice stored at 25°C without preservative (T2B2). Therefore, chilling combined with use of preservatives are able to retard spoilage and slowed down deterioration of sensory attributes in pineapple juice.

Abstract

Okra pudding is one of the dessert foods prepared from agar ingredients. Making okra as a pudding is expected to have more vitamin content than pudding in general. This study aims to determine the effect of different soaking time and agar concentration on crude fiber content, total sugar and organoleptic quality of okra pudding (Abelmoschus esculentus). This study used a Completely Randomized Design (CRD) with two factors, namely immersion time of okra (2, 3 and 4 hours) and agar concentration (2, 3 and 4%) each treatment was repeated 3 times. Determination of the best treatment of all research parameters was carried out using the effectiveness test. The results of the study showed that different lengths of fertilization and concentration had a significant effect on crude fiber content, total sugar and organoleptic quality.

Abstract

Since the 2016 economic crisis, the number of poor people in Indonesia has increased. One of its impacts was the increasing number of street children. Street children are one of the conditions of children in a difficult situation and vulnerable livelihood, mainly on the aspect of health and their future. The aim of this research is to understand the nutritional status of street children as the scientific basis for further intervention programs. This research utilises the discrete-analytic observation by using quota sampling of 30 street children in the Tembokrejo Village. Nutritional status was assessed using the anthropometric parameters of height according to age and sex and carried out during 48 hours to determine their diet and consumption level. This research concluded that 70% of street children have poor nutritional status and only 6.7% have good nutritional status, most common diet patterns for street children are rice, side dishes and vegetables, level of consumption is still below the Nutritional Adequacy Rate (AKG) and no significant relationship between nutritional status and consumption level. This research suggests that intervention programs on street children need to be implemented to prevent further serious nutritional problems.
