| dc.description.abstract | Expired liquid milk waste is waste that has not been considered optimally managed. The
management of expired liquid milk waste can be reduced by utilizing black soldier
fly (Hermetia illucens) as a feed medium for BSF larvae. This is done because BSF larvae
are able to decompose waste effectively and on the other hand BSF larvae can be used as
animal feed media. The purpose of this study is toanalyze the potential for waste
reduction, analyze the effective feeding rate of BSF larvae, andanalyze the proximate test
value of BSF larvae.
This study was conducted experimentally for 21 days with a larva count of 100 heads
per biopond using expired liquid chocolate milk. The results showed the percentage of
reduction rates based on treatment 1 to treatment 8 in this study was 90%; 86.94%;
86.94% ; 84.84%; 81.90%; 74.97%; 84.84% and 74.97%. In addition, an
effective feeding rate was obtained in treatment 2, namely treatment
with expired chocolate liquid milk waste of 1500 ml which obtained the highest survival
rate (SR) value of 95%. The results of the proximate test analysis of BSF larval moisture
content with the highest percentage results starting from P7, namely 70.57%, P4 by
70.54%, P8 by 66.91%, P2 by 66.13%, P5 by 64.81%, P6 by 64.63%, P3 by 53.32%, and
P1 by 52.29%. The highest BSF larval protein content test started from P3 at 13.12%,
P2 at 13.02%, P1 at 12.09%, P7 at 10.57%, P4 at 10.12%, P5 at 9.31%, P6 at 8.87%, and
P8 at 8.64%. The highest BSF larval fat content test started from P2 at 39.55%, P1 at
39.39%, P5 at 38.06%, P7 at 37.94%, P8 at 37.52%, P6 at 33.23%, P4 at 32.03%, and the
lowest fat content at P3 at 31.16%. Based on observations in this study, BSF larvae can
develop and reduce waste properly using expired liquid chocolate milk waste media
based on the treatment that has been determined in this study. | en_US |
