Performa dan Laju Pertumbuhan Maggot Hermetia illucens Pada Pakan Protein Tinggi dengan Kadar Air Berbeda

Abstract

Budidaya larva Hermetia illucens berpotensi menjadi sumber protein alternatif yang berkelanjutan, tetapi masih terkendala oleh variabilitas kadar air dan nutrien pada substrat organik. Penelitian bertujuan mengevaluasi pengaruh kadar air terhadap konsumsi nutrien, performa, laju pertumbuhan, dan kualitas nutrien pada pakan protein tinggi. Penelitian ini menggunakan rancangan acak lengkap dengan empat perlakuan dan enam ulangan. Perlakuan terdiri P1 = kadar air 56,73%; P2 = kadar air 63,84%; P3 = kadar air 70,84; P4 = kadar air 74,64%. Parameter yang diamati adalah konsumsi nutrien (BK, PK, LK, dan karbohidrat), performa, dan laju pertumbuhan, serta kandungan nutrien larva. Analisis data dilakukan dengan ANOVA dan uji Duncan. Hasil menunjukkan konsumsi nutrien, bobot, tingkat kelangsungan hidup, dan laju pertumbuhan maggot pada P4 nyata lebih tinggi dibandingkan perlakuan lainnya. Simpulan penelitian ini P4 dengan kadar air 74,64% dan protein kasar 20,18% dapat meningkatkan konsumsi nutrien, performa, dan laju pertumbuhan dengan kualitas nutrien tepung maggot Hermetia illucens yang relatif sama.

The cultivation of Hermetia illucens larvae has the potential to be a sustainable alternative protein source, but is still constrained by variability in water and nutrient levels in organic substrates. The study aimed to evaluate the effect of moisture content on nutrient consumption, performance, growth rate, and nutrient quality in high protein feed. This study used a completely randomized design with four treatments and six replicates. The treatments consisted of P1 = moisture content 56.73%; P2 = moisture content 63.84%; P3 = moisture content 70.84; P4 = moisture content 74.64%. Parameters observed were nutrient consumption (DM, CP, eter extract, and carbohydrate), performance, and growth rate, as well as larval nutrient content. Data were analyzed using ANOVA and Duncan's test. The results showed that nutrient consumption, weight, survival rate, and growth rate of maggot in P4 were significantly higher than other treatments. The conclusion of this study is that P4 with a moisture content of 74.64% and crude protein of 20.18% can increase nutrient consumption, performance, and growth rate with relatively similar nutrient quality of Hermetia illucens maggot meal.
