Abstract
This study investigated the effects of utilizing a mixture of slaughterhouse waste (SW) and rice bran (RB) as a growing medium on the morphometric traits of Black Soldier Fly (BSF) larvae. The research followed a completely randomized design with five treatment groups, namely T0: 100% SW (control), T1: 75% SW + 25% RB, T2: 50% SW + 50% RB, T3: 25% SW + 75% RB, and T4: 100% RB. The morphometric traits examined in this study included the larvae body length at 19 days (LBL19), larvae body width at 19 days (LBW19), larvae body length at 29 days (LBL29), and larvae body width at 29 days (LBW29). The results demonstrated that using SW as the sole medium (T0) could effectively support the growth of BSF larvae, but the morphometric traits of larvae in T0 were relatively modest. Interestingly, when RB was used to partially replace SW, it had a dose-dependent effect. T1 led to significant improvements (P<0.05) in LL19, LL29, and LW29. Conversely, the morphometric traits of BSF larvae in T2 and T3 did not exhibit significant changes (P>0.05) compared to the control. On the other hand, the use of T4 significantly enhanced (P<0.05) all morphometric traits of BSF larvae (LL19, LW19, LL29, and LW29). In conclusion, this study reveals the significant potential of the Black Soldier Fly in managing slaughterhouse waste. Moreover, substituting 25% of the slaughterhouse waste with rice bran can be considered an effective growing medium for enhancing the morphometric traits of Black Soldier Fly larvae.
