Abstract

The study was aiming at investigating for both chicken and fish feet by using substitution materials which so far is used as by product. These substitution feeds were comprised of palm oil sludge, shrimp shell, gold snail, and by product from leather fleshing. Feed formulation, were based and Least square methods represented in Feedmania program and calculated by using computer. These raw materials can be substituted for amount parts of conventional materials e.g. yellow corn, soybean meal, and fish meal. Based on feed consumed for broiler chicken, it is obtained the result as follow feed convertion ratio (FCR) was 1.95/1, and the feed efficiency for fish was 41%.

Abstract

Torbangun leaves could be extraxted to produce powder whice could be used as a raw material for nutraceutical or medicenal industri. techno economic analysis was conducted to evaluate the financial viability of the production unit of torbangun extract powder. the results of analisis showed that the production unit of torbangun extract powder was very feasible financially. based on the techno economic analysis, the production unit of torbangun extract powder resulted the net present value (NPV) i.e. Rp 650.170.746, internal rate of return (IRR) i.e.36,73% and pay back period i.e. 2,72 years. the break oven point of the production unit of torbangun extract powder was Rp 242.979.681 per year and the based price was Rp 355.239 per kg. the sensitivity analysis showed that the viability of the production unit o torbangun extract powder was very sensitive to the changes in the raw material cost,product price,and yield of the process. on the other hand the changes in the investment cost, electricity, and and working days,ware not sensitive to the viability of production unit of torbangun extract powder.

Abstract

Antioxidant could be defined by several means. Antioxidant is a substance that could postpone and delay oxidation of molecule substrate in human body ,i.e ; protein ,carboydtrate,lipid and DNA, by oxidant. antioxidant that works in the human bodys biological system is called a  biological antioxidant Biological antioxidants can be grouped into :1) enzymatic antioxidants (endogenous) ,2) non-enzymatic antioxidants (endogenaous) and, 3) antioxidants from food (exogenous0.Enzymatic antioxidants (endogenous) include superoxide dismutase ,catalase ,glutathione peroxidase, glutaredoksin, tioredoksin, peroksiredoksin ,and coenzyme q10.non-enzymatic antioxidants (ENDOGENOUS) are carotenoids,vitamin E  and vitamin C those antioxidants are able to work in hydrophobic and hydrophilic cellular environment so as to from a strong network of cooperation in preventing the occurrence of oxidative damage .some of the functions of antioxidants in the human body that can be expressed are ; preventive defense the human body against oxidants ,strong defense system against free redicals ,prevent the occurrence atherosclerosis in blood vessels,regulation of metabolism such as disabling lipoksigenase.

Abstract

Study on Extraction of Theobromine from Cacao seed has been conducted. The study is aimed at evaluating the extraction of theobromine effectiveness using Pavia Method and the modification of Pavia Method. The modification of Pavia Method was based on variation of MgO level and variation of organic solvent used. The variation of MgO level were 6 gr, 3 gr, and 0 gr, and the variation of organic solvent used were etanol, chloroform, and etyl acetate. The result of study showed that there was no significance influence of variation of MgO level on the weight and concentration of theobromine extracted. While the variation of organic solvent used showed significance influence to the weight and concentration of theobromine extracted. The best extraction result was obtained when using ethanol when using ethanol as an organic solvent.

Abstract

Cacao beans processing into product may affect active compound contents in the final products, especially catechin and  epicatechin. Temperature treatments during cacao processing can induce epimerization reaction of (-)-epicatechin to be (-)-catechin. Therefore, catechin and epicatechin ratio in the samples would be change. The aim of the was to know imfluence during cacao beans processing, especially cathechin and epicatechin concentration. Samples taken during the process were cacao nib, cacao mass, cacao powder, and butter. Analysis of catechin and epicatechin in samples was carried out by liquid chromatography mass spectrometry. Analytical for catechin were using mobile phase A (0.1 %formic acid in deionized water) and mobile phase B (acetonitril-methanol = 50:50) at flow rate of 0.5 ml/min. gradient elution were set at 0 minutes (10%B), 15 minutes (35%B), 20 minutes (40%B), 30 minutes (50% B), 35 minutes (60% B), and 35.1 minutes (105 B). Mass sprectrometer was set at ESI voltage (-) 3500 volt, desolvation temperature 300 oC, nubelizer pressure 50 psi, desolvation gas 10L/min, and fragmentor voltage (-) 160 volt. Results of the research showed that of catechin and cacao nib, cacao mass and cacao powder were 1:21,7; 1:20,0; and respectively. Heat treatments during cacao mass processing sowed a decrease tendency of catechin and epicatechin concentrations.
