Abstract

This research aimed at investigating the effect using molasses and cornmeal as additives with Lactobacillus sp. and Streptomyces sp. as inoculums during fermentation on the quality of silage flour made from dead chickens. The study was conducted using a completely randomized factorial design, consisting of 2 factors with 5 replications. The materials used were the newly dead chickens which were chopped and mixed thoroughly with all ingredients; then transferred into a 5 liters plastic box for fermentation. Observations were made after 3 weeks fermentation, including: a) physical characteristics, b) microbial contents, and c) nutritional contents. The data were calculated using variance analysis utilizing computer program of SPSS version 21.0. It was found that based on the protein contents the Lactobacillus sp. (19.0%) was better than the Streptomyces sp. (17.8%) if combined with molasses and corn meal as the accelerators. However, the fat contents produced were relatively similar for both of the inoculums (mean of 37.8%). It can be concluded that in order to obtain a best fermented product in terms of the protein and fat content, the dead chicken should be fermented using molasses and cornmeal as the accelerator and Lactobacillus sp. as the inoculum.

Abstract

This study was to examine the effect of fermentation, inoculation, and the proportion of carbonsources on the quality of organic fertilizer made from fermentation of liquid waste collected fromchicken slaughterhouse in Jakarta area. The parameters being tested included fermentation, microbialinoculation, and carbon source proportion. The observations were made after three weeks offermentation on the color, odor, pH, contents of elements C, NH4, NO3, total-N, P2O5, K2O andpathogenic microbes (Fusarium sp., Coletotrichum sp., Salmonella sp. and Eschercia coli). The fertilizerwere implemented for green chinese cabbage in six locations. It was found that the aerobic fermentationsystem combined with inoculation of the decomposer microbes (Lactobacillus spp.) and the addition20% (v/v) of a carbon source was the most appropriate method of fermentation in the production ofliquid organic fertilizers from liquid waste of chicken slaughterhouse. The quality of the fertilizer whichis based on physical, chemical and biological characteristics and crop responses still less than the similarcommercial fertilizer (EM4). Nevertheless, the nitrogen and phosphor contents of this liquid fertilizer(92,000 ppm and 143,000 ppm) were significantly higher (P<0.05) than the EM4 (0.07 and 3.22 ppm).
