Abstract

The purpose of this study was to analyze and to compare the level substitute of red bean flour (Phaseolus vulgaris L) in producing porriddge for the baby foods. The level substitutes of flour are from 0%, 10%, 20%, 30% and 40%. The study showed that the 30% substitute has the highest contents in protein (16,37%) and energy (103,4 cal). It is recommended that the baby should eat 165-gram porridge per day to fulfill the nutrient requirement.

Abstract

This study focused on the deacidification and decoloration of crude jatropha oil using microfiltration membrane. The experiment was conducted with hydraulic-pressed jatropha oil and polypropylene (PP) membrane hollow fiber with a molecular weight cut-off (MWCO) of 0.01 μm and a permeation area of 1 m2. Several tests were carried out to define the best performance (permeate flux, free fatty acid reduction and clarity) by studying the influence of duration and frequency of backflush.  Permeate flux was low but remained stable for a long period.  No long-term fouling appeared during the membrane processing. The permeate flux increased with transmembrane pressure. In addition, the backflush treatment can recover and increase permeate flux.   The higher permeate flux of 8.42 l/m2.h was obtained under duration and frequency of backflush of 6 seconds and 15 times, respectively. Furthermore, microfiltration membrane was found to have a positive effect on color reduction, but was not affective for deacidification.

Abstract

This paper expressed the level of glycemic index and content of resistant starch of sago noodle. Determination of starch resistant of sago noodle is necessary because it is correlated with the value of glycamic index. Resistant starch content was determined by enzymatic process through glucooxydase method. RS content from four kinds of sago noodle ranged between 7,55 - 9,45 mg/g substances. Pancasan sago noodle showed the highest RS content, and this was further used to analysis the glycemix index.The glycemic index was determined based on ratio of area under blood glucose curve which represent total carbohydrate available from the 50 g glucose to the area under blood glucose curve which represent the glucose content after consumption of 50 gram glucose. The tested used seven health volunteers and resulted in glycemix index about 28. This level was considered low affect the blood glucose consuming. The sago noodle therefore the noodle can be constued by diebetes people Key words : resistant starch, glycemix index, sago noodle

Abstract

The production of fatty acid methyl ester (FAME) by direct in situ alkaline-catalyzed transesterification of the triglycerides (TG) in Jatropha curcas seeds was examined. The experimental results showed that the amount of Jatropha curcas seed oil dissolved in methanol was approximately 83% of the total oil and the conversion of this oil could achieve 98% under the following conditions: less than 2% moisture content in Jatropha curcas seed flours, 0.3–0.335 mm particle size, 0.08 mol/L NaOH concentration in methanol, 171:1 methanol/oil mole ratio, 45.66 oC reaction temperature and 3.02 h reaction time. The use of alkaline methanol as extraction and reaction solvent, which would be useful for extraction oil and phorbol esters, would reduce the phorbol esters content in the Jatropha curcas seed cake. The cake after in-situ transesterification is rich in protein and is a potential source of livestock feed. Further, the the toxicity studies were also investigated on male rate by feeding the seed cake after after in-situ transesterification as well as the from solvent and mechanical extraction. Food intake, growth rate, protein efficiency ratio (PER) and transformation index (TI) showed that the meal is potential as protein supplement to livestock feed.

Abstract

The concept of green eco-tourism is a concept of regional development for environmentally sustainable tourism activities. Tourism activities have a significant effect on the development and improvement of the economic, social, cultural sectors and the quality of the surrounding environment which subsequently causes the global issue of World Tourism Organization (WTO) to emerge. It is then relevant to apply the concept of eco-green tourism in developing the strategic areas intended for tourism in line with the program of the government of Surakarta city which aims at developing the city within the concept of eco-culture city.Some tourist villages (kampung wisata) with local wisdom potentials as the historical areas in Surakarta city are still not handled optimally. This trend can be seen in some of areas which have begun to lose their original characteristics and have even changed function. This phenomenon will slowly and certainly erode the local wisdoms of the historical villages which will eventually cause the unique characteristics as the local potentials of the city to disappear.  Therefore, one of the right and integrated actions to handle such a problem is the research model of development of the tourist villages through LID (Low Impact Development) by having the concept of eco-green tourism.The objective of this research is to formulate the model of development of the tourist villages through LID (Low Impact Development) in bringing eco-green tourism into reality. This formulation is based on descriptive explorative method. This research was conducted in the historical area of Kauman tourist village which still has the authenticity of potentials of the value of characteristics of high local wisdoms which are still in existence and development.The results of this research are the model formulation for policy in developing Kauman tourist village. Such a policy model is expected to be able to become the pilot project of the development of the tourist villages not only in Surakarta city but also in other tourist cities in Indonesia in general through the implementation of eco-green tourism on the basis of the concept of green architecture which will not only conserve the tourism, cultural, and environmental assets, but also empower the prevailing local wisdoms.

Abstract

Low energy nano technology research with black cumin materials is still limited. Encapsulation of black cumin extract nanoemulsion has been developed and the products have been characterized. The aims of this study are determining the extraction method of black cumin seed, formulating black cumin extract nanoemulsion by spontaneous emulsification technique, and encapsulating black cumin extract nanoemulsion. Three stages of experiments were done in this study, i.e. extraction, nanoemulsification and encapsulation. First, extraction was done using maceration and reflux method and the best result was sent to the nanoemulsification process. Second, a spontaneous nanoemulsification was performed involving organic phase (black cumin extracts were dissolved in ethanol 70%), and water phase (Tween 80 solution with three different percentages 1, 2 and 3% w/w) to produced the best nanoemulsion. Third, the best nanoemulsion based on size, homogeneity, and stability of the particles, was encapsulated using two different encapsulating material compositions, i.e. maltodextrin (100%) and combination of maltodextrin and soy protein isolate at a ratio 80 and 20 (w/w). The results showed that three-hour reflux method produced better black cumin extract properties than that of maceration method. A percentage of 3% surfactant gave a stable nanoemulsion with average droplet size of 10.93 nm. Reconstitution of nanoemulsion encapsulation product that has more spherical globules, indicated efficient encapsulation process. The use of combination of maltodextrin and soy protein isolate provided a better preservation of phenolic content and antioxidant capacity as compared to the use of maltodextrin alone.
