Abstract

The experiment to study the effect of coconut kernel (RCK) and fermented coconut kernel wastes (FCKS) on feed efficiency and income over feed cost of broiler was conducted from September to October 2006.  The experiment used 100 DOC (Arbor Acres Strain) broilers. A Completely Randomized Design was applied with 5 treatments with 4 replicates.  The treatments were R0 = 0% RCK and RCKF; R1 = 6% RCK; R2 = 12% RCK; R3 = 6% RCKF and R4 = 12% RCKF. The results of the experiment showed that the treatment effects on the feed efficiency of broiler were highly significant (P<0.01).  The treatments R3 and R4 were more efficient than R1 and R2. The R4 treatment produced the best income over feed Cost (± Rp 6897.88), whereas the R2 treatment shown the lowest one (± Rp 4396.65).  In order to apply the waste of coconut kernel, it is recomended that it should be fermented at first to improve its quality and to increase the income over feed cost of broiler.

Abstract

The  aim  of  this  experiment  was  to  analyse  chemical  composition  and  functional  properties  of  corn  starch  from various  corn  varieties  extracted  with  natrium  bicarbonat  solution.  Corn  kernels  of  N35,  Sticky  corn,  yellow  Srikandi  and yellow local varieties were processed into starch. The starch was extracted with 1% natrium bicarbonat solution (1:10 [w/v]).  Starch of commercial corn was used as a control. This experiment used Randomized Block Design with three replications. Results of this experiment indicated that the highest starch, amylose, fibre and free fatty acid contents were obtained at starch of yellow local variety; and the highest sugar, protein and lypide contents were found at yellow Srikandi variety, whilst the highest ash content was achieved at N35 variety. Starch of sticky  corn possessed the lowest amylose  content, but had the highest amylopectine content. The highest water absorbtion and solution rate were obtained at starch of yellow local variety.  Furthermore, the highest oil absorbtion rate was achieved at starch of sticky corn variety. Corn starch extracted with natrium bicarbonat solution had a lower quality compared to commercial corn starch, and therefore the corn starch recovered here apparently should not be recommended as a food source.

Abstract

The research conducted was aimed at increasing the use of arenga starch and finding an optimal processing method of instant starch noodle made of arenga starch. The instant starch noodle was made using a bihon method.  The stages of the bihon  method  process  including  determination  of  starch/water  ratio,  duration  of  cooking,  and  optimal  aging  time.  The starch/water  ratio  and  duration  of  cooking  were  established  based  on  the  degree  of  freedom  of  inter-molecular  binding (gelatinization and retro-gradation) with a minimal score of 80% in accordance with the instant noodle requirement (SNI 01-3551-1994). While, the determination of aging time  was based on physicochemical properties of  the instant starch noodle produced. The analysed physicochemical properties included water content, the degree of freedom of inter-molecular binding, cooking rate, cooking loss, tensile strength, elongation, texture and white degree. The results of the research indicated that the best instant starch noodle process using the bihon method was done at starch/ hot water ratio of 1:0.9 (v/v), cooking duration of 15 minutes, and aging time of 60 minutes. The physicochemical properties of the instant starch noodle were at water content of 8.57%, the degree of freedom of inter molecular binding of 83.23%, cooking rate of 3.31 minutes, cooking loss of 7.06%, tensile strength of 0.09 MPa, elongation of 7.44%, texture of 12.29 N and white degree of 75.10%.
