Abstract

This study aimed to determine the change of quality parameters, to determine the critical quality parameter and to predict the distribution expired time of snake fruit candy using Q10 method. Snake fruit candy was stored at three different storage temperatures, namely 35, 45 and 55oC for 20 hours. Each storage room was loaded with 126 candies and observation was done every 4 hour on parameters of texture, aroma, color and flavor of the candy. The results showed that the longer the storage, the value of candy texture increased from an average of 7,06 N to 250,20 N. Meanwhile, the score of aroma of candy decreased from an average of 4,13 to 1,00. The score of color also decreased from an average of 4,93 to 1,00. The same phenomenon was also observed on flavor of candy which decreased from an average of 4,67 to 1,00. The critical quality parameter of the snake fruit candy was flavor which followed the first reaction order. The Q10 of the flavor deterioration was determined at the basic temperature of 45oC and it was found its value was 1,94. By using Q10, it was predicted that distribution expired time of snake fruit candy stored at temperature distribution of 15, 25, 35, 45, and 55oC was 220 hours (9,19 days), 114 hours (4,73 days), 58 hours (2,44 days), 30 hours (1,25 days), and 15 hours (0,65 day), respectively.

Abstract

This aims of this research were to determine the effect of the use of an ice cooling media with the addition of salt and ice cooling media comparisons with the raw materials of fish on the quality of fresh fish. This research used factorial experimental design with two factors, namely the use of ice cooling media with the addition of salt and ice cooling media comparison with raw fish. Factors adding salt consists of four treatments, without the addition of salt, the addition of salt 10%, 12.5%, and 15% of the amount of ice used. While factors ice cooling media comparisons with the raw materials of fish is 1:1 and 1:1.5. Parameters of observation in this research was the long time cold chain system, pH, organoleptic appearance, organoleptic odor, organoleptic texture, histamine, TVB, TPC. The results of this research indicating that the use of an ice cooling media with the addition of salt and ice cooling media comparisons with the raw materials of fish, as well as the interaction between treatments giving effect of good on the quality of fresh fish. The interaction addition of salt as much as 15% and the ratio of 1:1 gives the best results on the quality of fresh fish with characteristics, long time cold chain system of 11 hours and 24 minutes, the pH value of 6.25, a fresh appearance (8,4), the smell of fresh (8.1), the texture of fresh (8.0), histamine 7,90 mg / 100 g, TVB 10,40 mg / 100 g, TPC 7,4x103 colonies/g.

Abstract

The purpose of this study were to design fixed-dome type bioreactor and to measure its performance. through biogas prosessing that was made from cow dung feces with optimal process temperature. The components of the bioreactor were: biomass inlet, digestion tank, the bioreactor mantle, the bioreactor dome, and outlet basin for sludge. Through design analysing were obtain spesification of bioreactor was 426 cm long, diameter of 160 cm, 200 cm height and a total volume of 3.04 m3. The mantle of bioreactor which 10 cm thick was filled with sand. Results of bioreactor performance test showed that for 35 days the temperature of the biomass in the bioreactor was greater than the ambient temperature. The larger gap between both temperature was 6.8° C which achieved at day 27th of fermentation and the biomass temperature was 31° C. The gas pressure inside the bioreactor increased in accordance with the increase of biomass temperature. Biogas production per day achieved at average of 2.,31 liter with 2.5 cmH2O preassure.

Abstract

This research aimed to determine the effect of air circulation treatment toward cow manure sludge fermentation process and to determine the quality of sludge that was produced accordance to Indonesia National Standard (SNI) of Compost No. 19-7030-2004. The air circulation treatment was done by using aerator. There were three combination treatments of air circulation: the aerator and drum with coat, aerator and drum without coat, and without aerator and drum without coat was applied as a control. The results of this study indicate that each treatment in the fermentation process had a different temperature fluctuations between 21.56 to 24.41 °C. Temperature is a requirement for mesophilic microbial growth. The acidity condition of the sludge material at the beginning until the end of fermentation was the whole treatment has fulfilled the optimal conditions of fermentation process, with range of pH was from 6.92 to 7.65. The influence of air circulation inside the drum without the coat of rice husk can accelerate the breakdown of proteins into C-organic and N-total, that was C-organic= 24.22%, and N-total = 1.80%. The compost that produced by the fermentation process had the characteristic ratio C / N = 13.46 and had a blackish brown colour rendition. Characteristics of compost according to the quality of compost SNI No. 19-7030-2004, that is pH = 6.80 to 7.49, C-organic = 9.80 to 32%, N-total = 0.40%, the ratio of C / N = 10-20.

Abstract

Crop residues such as supreme variety rice straw can reach about 25 ton/ha which can be used as raw material for composting. The purpose of this research were to determine the effect of channels aeration of the composting process, and to find the compost quality produced from rice straw. Two treatments were conducted, namely: P1 : rice straw composting with aeration channel; P2 : rice straw composting without aeration channel. About 1.5 m long, 1 m wide and 1 m high of dimension of compost heap respectively were conducted. The parameters measured were temperature, humidity, water content, yield, pH, nitrogen, carbon and C/N ratio. The composting process lasted for 12 weeks. The composting process in the composting treatment with aeration channels tend to run slower than composting treatment without aeration channels. The quality of the compost produced from rice straw on the treatment P1 and P2 were appropriate the standard compost appointed by Peraturan Menteri Pertanian Nomor 70/Permentan/SR.140/10/2011.
