Abstract

Soybean is important commodity because it is consumed by the whole communities. Soybean plays important role in national food security. In fact, the needs for soybeans currently still depend on import of soybean seeds. The stakeholders and communities have made some efforts to increase soybeans production, and one of them is providing superior and high-qualified varieties, as well as profitable for farming. Objective of the study was to know relationship between agronomic characters and economic values in soybean varieties assessment. The study was to analyze the farming of new superior varieties in comparison with local superior varieties by applying different dose of fertilizer. Furthermore, the research was carried out to look for superiorities of the varieties before they are released. Conclusions of the research are (1) the harvest yield per hectare showed that the treatment of YS2 and YS3 have the highest yields with average values 2.4 and 2.2 tons/ha, respectively. (2) The highest farming income was derived from the treatment of YS0, (3) Extra expenses for farming which were expended for both varieties of Yasi 6 and Grobogan will be able to increase the harvest yield but could not afford to raise income, (4) Yasi 6 could be cultivated in accordance with the farmers’ habits and will be able to raise income.

Abstract

Cowpea is a type of legume that contains a lot of protein. One of the uses of cowpea as a food ingredient is protein isolate. The purpose of this study was to determine the type and concentration of chemicals suitable for cowpea protein isolate as well as its physical and chemical properties. Implementation of modified cowpea protein isolate was divided into three stages. The first stage is to determine the best results from the addition of certain types and concentrations of chemicals: a) CH3COOH (3%, 5%, 7%); b) CaSO4 (0.25%; 0.30%; 0.35%) and c) MgSO4 (0.25%; 0.30%; 0.35%). The second stage is to combine each of the best treatments. There are three treatments, namely treatment A is the addition of the best CH3COOH concentration with the best CaSO4 concentration. Treatment B is the best concentration of CH3COOH and the best concentration of MgSO4. Treatment C was the best concentration of CaSO4 and the best concentration of MgSO4. The third stage is the analysis of the physical and chemical properties of the treatment combinations formed. Each treatment was replicated three times. The data obtained were then analyzed descriptively. The results of the analysis are presented in the form of tables and histograms. The best treatment of chemically modified cowpea protein isolate was in treatment C (addition of 0.35% CaSO4 and 0.35% MgSO4), which had a gel strength texture of 13.87 gram force/0.1mm; with a water content of 81.04%; ash 6.77%; and protein 92.53%; and has the highest protein solubility at pH 8 of 22.47 mg/g.
