Perkembangan dan Kandungan Nutrisi Larva Hermetia illucens (Linnaeus) (Diptera: Stratiomyidae) pada Bungkil Kelapa Sawit

Abstract

<jats:p>Hermetia illucens, is used as a reducing agent of palm kernel meal (PKM), as well as one of alternative protein sources for aquaculture purposes. Information about biology of H. illucens is absolutely required in mass production. The objectives of these researches were to study the development of H. illucens including the effect of supplementary food to the adult, and nutrient content of the immature stage. The sample of 20 larvae from each 3 replicates were measured and weighed on 0-19th day (larva) and 24th day (pupa) from egg hatching. H. illucens adults were fed by water and honey 5% (v/v). Eggs were collected and counted. Nutrient content of immature stage: 5, 10, 15, 20 days old (larvae), and 25 days old (prepupae) reared on PKM were analyzed proximately. Dry matter was determined by weight loss on drying at 105 oC during overnight. Crude protein was determined by Kjeldahl procedure (N x 6.25), crude fat by soxhlet (ether extract), crude ash by determining the residue after heating at 550 oC for 4–5 h. Data were analyzed descriptively by average from triplicate. The development of H. illucens was shorter than those in previous studies as the differences of abiotical factor. PKM was a suitable medium for development. It was better, however, to fed the adult with honey since it could enhance the fecundity. The young larva certainly contained the best quality of nutrition. To meet the quantity of mass production, however, the use of the elder larva (bigger) was suggested.</jats:p>

Studi Laju Umpan pada Proses Biokonversi Limbah Pengolahan Tuna Menggunakan Larva Hermetia illucens

“…Telah banyak penelitian (Diener, Zurbrügg, & Tockner, 2009;Fahmi, 2015;Li et al, 2016;Rachmawati, Buchori, Hidayat, Hem, & Fahmi, 2010;Saragi & Bagastyo, 2015;Zheng, Li, Zhang, & Yu, 2012) yang m enyatakan bahwa larv a BSF memberikan banyak kelebihan dalam mereduksi limbah organik dan berguna sebagai bahan pakan ikan. Larva BSF mampu hidup dan berkembang dalam berbagai media organik karena sifatnya yang memiliki toleransi pH yang luas (Mangunwardoyo, Aulia, & Hem, 2011).…”

The Utilization of Insects as Feedstuff in Broiler Diet

“…Jenis insekta yang umum dibudidayakan adalah dari jenis ulat Hongkong (T. molitor l) dan black soldier fly (H. illucens). Rachmawati et al (2010) melaporkan bahwa bobot H. illucens yang dibudidayakan pada media bungkil kelapa sawit pada umur 4; 6; 8; 10; 12; 14; 16; 18; dan 24 hari berturut-turut adalah sebagai berikut 10; 60; 100; 120; 140; 160; 170; 180; 180 mg/ekor. Morales-Ramos & Rojas (2015) melaporkan bahwa pertambahan bobot hidup larva T. molitor selama 12 minggu untuk setiap gram pakan yang dikonsumsi bervariasi antara 181-227 mg. Fauzi & Sari (2018) melaporkan bahwa budidaya black soldier fly yang dilakukan dengan 100 kg bahan baku media tumbuh, dapat menghasilkan larva sebanyak 60-70 kg larva.…”

“…Pemanenan larva black soldier fly dilakukan sebelum umur 37 hari, umur dimana larva akan berubah menjadi lalat. Rachmawati et al (2010) mengatakan bahwa ratarata bahan kering larva black soldier fly pada berbagai umur adalah 36,28%, sehingga dapat diperhitungkan dari 100 kg bahan baku media tumbuh, dapat menghasilkan larva sebesar 21,8-25,4 kg bahan kering larva. Kandungan lemak kasar pada larva black soldier fly dipengaruhi oleh media tumbuh yang digunakan.…”

“…Kandungan lemak kasar pada larva black soldier fly dipengaruhi oleh media tumbuh yang digunakan. Kandungan lemak kasar black soldier fly yang ditumbuhkan pada media bungkil kelapa sawit adalah 19,8% (Rachmawati et al 2010). Sementara itu, Liland et al (2017) melaporkan bahwa kandungan total lemak black soldier fly yang ditumbuhkan pada media tumbuh berupa tepung gandum menghasilkan total lemak 33.8%, sedangkan black soldier fly yang ditumbuhkan pada media tumbuh kombinasi tepung gandum dengan tanaman alga (50:50) menghasilkan kandungan total lemak black soldier fly sebesar 22,2%, black soldier fly yang ditumbuhkan pada media tumbuh 100% alga, memiliki kandungan total lemak sebesar 8,1%.…”

Technical Feasibility of Hermetia illucens in Integrated Waste Management, Renovated with Sewage Water, an Overview

“…As instance the protein content in larvae varies inversely to its age, assorted studies addressed varying protein percentage for different period of larval development such as ~61% for 5 days old larva (reported as optimum) and subsequent values were 45% and 41% for 15 and 20 days old larvae respectively [77]. Previous studies also quantified the amount of dry matter in young larvae which found to be varying between 20% and 45% of total body weight [67] [77]. Unlike the protein content dry matter found to be varying proportionally with the age of larvae and often higher values are encountered in consecutive instars stages.…”
