Abstract

It is noted that the delay of any information will attract some negative reaction because it would be useless. The objective of this study is to analyze the influence  of profitability, profit and loss, auditor opinion, public accountant size, auditor previous opinion, going concern and company size towards the audit delay in banking companies that have been listed in Jakarta Stock Exchange, Indonesia in 2005 until 2009. This research used census method on the companies that have been listed in Jakarta Stock Exchange. The analysis of hypothesis is using Multiple Regressions. Prior to hypothesis test, normality of the data test was done using kolmogorof-Smirnov test. The result of multiple regression model shows that audit delay was influenced by profitability and auditor previous opinion, with the  significance at 10%. Yet, profit and loss, public accountant size, auditor opinion, company size and going concern were not significant factors. Based on such results, it is recommended that the auditor should increase the effectiveness and efficiency of his audit performance and, for all existing studies; they should contribute to the current  literature on Auditing.

Abstract

A three by three factorial experimental design (cassapro levels 0, 5 and 10% x rice bran levels 0, 21 and 42%) was employed to study the effect of cassapro and rice bran and their interaction on boiler performance. All rations were formulated to be isonutrients . Each ration was fed to 40 three days old chicks, divided into 4 cages (10 birds/cage). Feed and water were given ad libitum during the 4 weeks trial . Feeding cassapro significantly (P<0 .05) improved body weight gain, with no significant effect on feed conversion ratio (FCR). Rice bran significantly (P<0 .001) reduced body weight gain and caused poorer FCR (P<0 .01) . There was a significant interaction effect of cassapro and rice bran on body weight gain (P<0.01) as well as FCR (P<0 .001) . It is concluded that cassapro contained some factors, which are most likely digestive enzymes, which enhhance digestibility of rice bran . Key words: Cassapro, Aspergillus niger, rice bran, broiler

Abstract

A trial was conducted to determine the effect of various level of cassapro (fermented cassava) and halquinol supplementation on the performance of broiler chickens . Experimental rations were formulated isoprotein and isoenergy with graded level of cassapro (0, 10, 20 and 30%) . The 20 and 30% cassapro ration were prepared without and with halquinol supplementation (60 ppm). Each ration was fed to 40 of three day old broilers, divided into 4 cages ( 5 males and 5 females per cage) for 4 weeks. Increasing the level of cassapro significantly reduced body weight gain (P < 0.005), increased feed conversion ratio (FCR) (P < 0.0005) with no effect on feed intake (P < 0.10) . Halquinol supplementation has no effect on feed intake, but significantly increased body weight gain (P <0.05) and improved the FCR (P < 0.01) . It is concluded that high level of cassapro in the ration will cause poorer performance of the birds, however it can be alleviated by halquinolsupplementation.   Keywords: Broiler, cassapro, halquinol

Abstract

A series of chemical, biological assay and growth trials were conducted to determine the nutritive value of hominy, relative to corn. The crude protein, ash, NDF and ADF content of hominy were 10.25%, 2.10%, 19.10% and 4.70% respectively, and are higher than the corn level, 8.5%, 0.40%, 2.30% and 1.90% respectively. While its crude fat (3.20%) and metabolize energy (3,020 kcal/kg) contents were lower than the corn level 4,40% and 330 kcal/kg. Seven hundred DOC broilers of commercial strain were used for growth trial for 42 days. The birds were divided into 5 treatments group with 4 replications (35 bird/replicate). Experimental rations, starter and finisher, were formulated with graded levels of hominy on the expense of corn (A = 0%, B = 33.3%, C = 50%, D= 66.6% and E = 100%) with similar level of crude protein and metabolize energy. Feed consumption was not affected (P>0.05) by the treatments, however body weight gain (BWG) and feed conversion ratio (FCR) were both significantly (P<0.05) affected by the treatments. Body weight gain of treatment A (1,712 g) was similar to treatment B (1,683 g) and C (1,682 g) but significantly (P<0.05) higher than treatment D (1,598 g) and E (1,570 g). Feed convertion ratio of treatment A (2.17) was similar to the treatment B (2.26) but significantly better (P<0.05) than treatment C (2.30), D (2.36) and E (2.39). Carcass quality was not affected by the treatments except for the shank color, where treatment A (7.38) was significantly yellower than the other treatments (B=2.50, C=2.75, D=1.75 and E=1.0). It is concluded that the protein content of hominy is higher than corn, but its metabolize energy was lower than the corn. Hominy could be included in the ration replacing corn up to 33.3% without affecting performance of the bird.   Key words : Poultry, hominy, nutrient

Abstract

Enzyme (mannanase and cellulase) activities and fibre (hemicellulose, cellulose and lignin) contents were determined during the fermentation course of palm oil sludge with Aspergillus niger TL (wild type) and A. niger ES I (an asporogenous mutant). The analyses were carried out at the incubation time of 3 and 4 days of aerobic fennentation and at 2 days of anaerobic fermentation afterward. The correlations between mamlanase activity with hemicellulose content and cellulose activity with cellulose content were calculated by linear regression . The activities of matutanase and cellulase are increasing during the aerobic fennentation, while in the anaerobic fennentation the enzyme activities are decreasing due to instability of the enzymes. The enzyme activities of ESI are higher than the TL. The regression coefficient is highly significant for correlation between mamlanase and hemicellulose content of fermented product by ESI (r = 0.83; P<0.01) . While other correlations are not statistically significant (P>0 .05) . Marutanase and cellulase activities were also detected after the fermented product dried at 60°C which indicated the enzymes are quite stable . Key words: Palm oil sludge, fermentation, cellulase, mamlanase, cellulose, hemicellulose, Aspergillus niger

Abstract

An experiment was conducted to improve the nutritive value of palm oil sludge (POS) by fermentation process. Aspergillus niger BPT and NRRL 337 were used into fermenting POS for three days and followed by anaerobic enzymatic process. The experiment was arranged in 2x3 factorial design i.e., enzymatic incubation time (2, 3, and 4 days) and environmental temperature during enzymatic process (room temperature and 40°C). Changes on chemical compositions (crude protein, true protein, ADF and NDF), in vitro dry matter digestibility (IVDMD) and protein digestibility (IVPD) were measured. The results showed that both A. niger BPT and NRRL 337 grew well on POS media with the best result at 3 days. The fermentation process by both strains increased crude protein and true protein of POS. The A. niger NRRL reduced the fiber content (ADF and NDF) more than A. niger BPT the IVDMD and IVPD were not significantly affected by fermentation process without enzymatic process. The IVDMD increased significantly when the fermentation followed by enzymatic process. Overall results showed that the best fermentation of POS was obtained by using A. niger NRRL followed by enzymatic process in room temperature for two days.

Abstract

The effect of continuous feeding of gliricidia on reproduction and production performances in second breeding of Javanese Fat-Tailed (JFT) sheep through the second breeding period was studied. Twenty six ewes post lactation at first lambing (body weight 22.5-26.5 kg) were divided into four treatment groups. Each group consisted of 6 animals except Group D had 8 animals. They were given King grass (Pennisetum purpureophoides) and gliricidia (Gliricidia sepium Jacq.) leaf with ratio of 100:0 (Group A = control), 75:25 (Group B), 50:50 (Group C) and 0:100 (Group D). Forages were given 2.5-3% (dry matter) of liveweight. All groups were supplemented with 100g/head/day concentrate (crude protein = 16%), but during late pregnancy and lactation they were supplemented at 200 g/head/day. Results showed that feeding gliricidia 25-100% of total forages improved body weight due to the increasing protein intake. The maximum concentration of progesteron increased from 0.81 to 2.78 ng/ml. The ovulation rate and prolification also increased significantly (P<0.05) from 1.6 to 3.0 and 1.33 to 2.38, respectively. Individual birth and weaning weights of the lambs were not affected. It is concluded that feeding gliricidia continuously up to 100% as forages and supplemented with concentrate gives positive effect on bodyweight gain, reproduction and production performances in second breeding of JFT sheep.   Key words : Sheep, gliricidia, reproduction, second breeding
