Abstract

The study was done in two stages. The first stages was aimed at making chicken feet bone meal (CFBM) and assessing the nutrient, including water, fat, ash, and calcium) contents of CFBM. A proximate analysis was performed. The second stage was aimed at finding the best organoleptic characteristics (color, taste, aroma, and texture) of CFBM to be used in soya bean tofu. The ratios of CFBM : soya bean tofu were 0.5; 0.75; and 1%.The inclusion of 0.5; 0.75; and 1% CFBM was found to give different organoleptic characteristics of tofu. However, treatment A1 (0.5% CFBM inclusion) was found to give the most preferred tofu. The nutrient contents of CFBM-treated tofu were 8.21% protein, 4.8% fat, 3.5% carbohydrate, and 0.08% calcium.The chosen treatment as a source of calcium was A1 (0.5% CFBM inclusion) as it had the highest score of 4.30 according to panelist’s preference on taste. The nutrient contents of AI-treated tofu were 76.59% water, 2.64% ash, 8.21% protein, 4.80% fat, 3.50% carbocydrate, and 0.08% calcium and the pH was 6.00.

Abstract

Colors are used to give more interesting appearance. Rosella (Hibiscus sabdariffa) flower is a natural color source as its red-colored flower contains high anthocyanin.The study was done in three stages. In the first stage, an extraction of anthocyanin pigment from Rosella bark was done. The treatments given in this study were to levels of extraction temperatures, namely room temperature and 60oC. The types of acids used included citric, succinic, oxalic, malic, and asetic acids. In stage 2, the acid that gave the best extraction result in stage 1 was used in different rates, namely 0.25, 0.5, and 0.75%. To determine the best extraction solvent, three solutions namely aquadest (A) and a combination of aquadest and ethanol (B) were used.Results showed that extraction temperature that gave the best anthocyanin rate was 60oC. The acid that produced the best extraction of bark and petals was 0.5% malic acid. Meanwhile, the combination of aquadest and 95% ethanol was found to be the solvent that gave the best result.

Abstract

Research action of society service project in implementing forages ammoniating technology in increasing sheep performances had been conducted in eight months at Desa Gede Pangrango Kecamatan Kadu Dampit Kabupaten Sukabumi. The project was aim to increase practical ability of sheep farmers in forages ammoniating technology, forages quality, and to anticipate forages supply problems in draft season. Methods to attain the project goal included: education, training, demonstrating, practicing, and feeding ammoniated forages. Afterward, the sheep fed ammoniated forages had been weight monthly for three months. Methods to measure attainment of this goal project included questionnaire based interviewing and field monitoring to sheep farmers, parameters to measure ammoniated forages quality based on physical characteristics of ammoniated forages, whereas sheep responses to ammoniated forages measured by palatability and a three-month live weight gain. Results of the research action concluded that sheep farmers accepted well to introduction of forages ammoniating technology and able to ammoniating forages by themselves. Ammoniated forages-molasses mixes with ratio of 1% urea and 1% molasses of dry basis forages increased live weight gain of sheep 0.87 – 1.44 kg/3 months and higher than the weight gain of sheep fed non-ammoniated forages. Feeding ammoniated forages-molasses mixes increased profitability of sheep farmers as high as 18% (Rp78,354.00) whereas feeding ammoniated cassava peel-molasses mixes generated profit up to 51.44% (Rp222,966.00) higher than feeding non-ammoniated forages. Supporting sheep supply and market assurances will maintain the continuity of feeding of ammoniated forages.

Abstract

Hydrogel is a colloid gel in which water is dispersed. The production of hydrogel from iles-iles glucomannan in Indonesia has never been studied. Results showed that with the help of sodium phosphate to form a cross bond, iles-iles glucomannan was able to form hydrogel with the capacity to absorb water up to 31% with a yellowish white color. It was expected that this hydrogel would be useful as a medium of transferring medicine into the body as, unlike commercial hydrogel made from polyacrylamide, it is not carcinogenic.

Abstract

The issue of energy crisis is one issue that developed in the world today. Indonesia has a national energy policy which aims to develop energy that can fulfill the needs of society as a cheap and affordable, one with biogas development. Dairy farm has a huge potential in renewable energy development. The largest population of dairy cattle in the District of Bogor there is in Cisarua and Megamendung Regency. The farmers already have a scale of 5 m3 of biogas installations with a total ownership of cow is 6 tails. Milk produced has a fluctuation in prices and production, so it needs to be studied further whether the business exploitation and utilization of dairy cow waste to produce instalation biogas 5 m3 scale is feasible to run both in normal conditions or in conditions of risk. The purpose of this research is to analyze non financial aspects like technical aspects; market aspects; aspects of management and social; and environmental aspects, analyze financially, and analysis of scenarios under conditions of price and production risk. The data described qualitatively and quantitatively. Results of non-financial analysis shows that this business is feasible to run. Financial analysis show the business is feasible because NPV Rp 82.401.004,07, Net B/C 2,20, IRR 23 percent, Payback Period 5 years 1 month and the business has a high level of risk on the condition of dairy production risk.

Abstract

Long chain omega-3 fatty acids such as Eicosapentaenoic acid (EPA) and Docosahexaenoic (DHA), were very important for brain development, immunity, retina and growth of child. One of natural source of these faty acids is fish which has been processed into variety food such as abon. The other source is modifying hen egg which potentially to be added into many kind of food after processed as egg flour. This research examine the effect of processing and storage of abon and eggs flour. The methode of this research was one-group pre post test (minimal control) and the date was prepared in tabulation. Processing in to abon ikan make EPA lost for 10,63% and DHA 7,63%. This product was acceptable, but the stability of the fatty acids were low, EPA lost 43,8% and DHA lost by 52,4% for 4 months. The eggs prepared by our lab contained 2,5% omega-3 fatty acid. To make egg yolk flour was used Spray Drying process. This process make EPA lost 43,94% and DHA 6,20%. After storing for 4 months, egg yolk flour was very stabile. Because of these reason, these products can be used to supplement fatty acids in daily diet. Eggs flour can be used in any food product to supply omega-3 fatty acid for the risk group.
