Abstract

The objective of this study was to determine the optimum values of nutrient (i.e. nitrogen, phosphorus, potassium) added from inorganic fertilizers (i.e. KNO3, SP-36, Urea) to some alternatives raw materials of organic fertilizer using linear programming. Some alternatives raw materials of organic fertilizer in this study were biogas waste (Formula I) and goat compost (Formula II). The content of total N, C-organic, organic matter content of P2O5, K2O and Cation exchangeable capacity (CEC) were analyzed as parameters. The results indicate that the formula II with goat compost as raw materials was the best formula which has the average nutrient element close to the national standard of organic fertilizers with 23.16% of C-organic, 2.20% of N, 2.19% of P2O5 and 0.69% of K2O. In addition, the production cost of organic fertilizer base on formula II was cheaper than other formula i.e. IDR 1.15/g. Keywords: organic fertilizer, optimization, linear programming

Abstract

Casein and phospholipids are natural compounds usually used concomitantly as emulsifier. This research was conducted to elucidate the adsorbed phospholipids composition that stabilized oil globule interface during fish oil emulsification by sodium caseinate and phospholipids. Emulsion was formed by homogenizing sodium caseinate solution (10% w/v) with various phospholipids concentration of 0, 0.5, 1.0, 1.5, 2.0, and 2.5% (w/v) at fish oil concentration of 20%. The results showed that the quantity of adsorbed phospholipids increased in line with increasing phospholipids concentration. Competitive adsorption occured among various phospholipids that indicated by compositional changes of adsorbed phospholipids at oil globule interface. Their preference to adsorb was influenced by their surface activities. Among various phospholipids, phosphatidylcholine had preference to adsorb due to its higher surface activity and quantity. Phosphatidylethanolamine had less preference to adsorb because of its lower surface activity. Meanwhile, phosphatidylinositol had less ability to compete due to its low quantity. The change of adsorbed layer in oil globule interface was caused by phospholipids-casein complexation and displacement of casein by phospholipids to occupy oil globule interface. Keywords: preference to adsorb, caseinate, phospholipids, emulsion, oil globule, interface, surface activity, competitive adsorption, displacement, adsorbed layer, complexation

Abstract

This research aimed to study the effects of two fermentation methods (fixed and unfixed) on HCN content, bulk density, moisture content, flour microstructure, and sensory properties of texture, colour, and flavor of cassava flour made from local cassava tuber of Tidore variety. Unfixed fermentation was conducted by replacing soaking water every one a day. Meanwhile at fixed fermentation, the soaking water was not replaced. The result showed that HCN content of cassava flour of fixed fermentation method was significantly lower than (p<0.05) on unfixed fermentation method. Moisture and starch content of fixed and unfixed fermented cassava flour was lower than unfermented cassava flour. Starch granule micrograph of fixed and unfixed fermented cassava flour had similar starch granule size. Texture, color, flavour of both fermented cassava flour did not differ significantly (p>0.05). Otherwise, fixed fermentation method using local cassava variety of Tidore could be suggested for producing cassava flour and was recommended as raw material for sagukasbi processing. Keywords: fermented cassava, sagukasbi, microstructure, starch granule, cassava flour, unfixed fermen-tation, fixed fermentation, HCN content

Jatropha oil has a potential roles as a grease lubricant base oil. This research aimed to study the differences of basic material compositions towards the grease qualities, to study the thickening agent which had the most suitable for grease production and to determine the best treatment combination of grease formulation using jatropha oil. The research used an experimental method. The tested factors were types of oil consists and thickening agent consists. Physicochemical variables observed were: dropping point, pH, texture and corrosion resistance. The result of the research showed that the differences of basic material compositions gave the influence to the grease dropping point characteristics. The addition of castor oil 15% could decrease the grease dropping point (from 101.33 oC to 99.08 oC) while the addition of mineral oil lubricant 15% could increase the grease dropping point (101.33 oC to 112.58 oC). The thickening agent which had the most suitable for grease production using jatropha oil was LiOH 3.5% + Al(OH)3 0.5% produced 128.83 oC of dropping point. The best formulation based on zero-one test method obtained at treatment of M3P6, i.e. the grease which has basic materials composition of jatropha oil + mineral oil lubricant 15% and thickening agent of LiOH 0.5% + Al(OH)3 0.5%. That formulation had the characteristic 138 oC of dropping point, pH 7.5, 4.63 mm/dt of texture (NLGI grade of 3) and corrosion resistance included in group 1b (dark orange).
