Modifikasi Pakan Larva Black Soldier Fly (Hermetia illucens) sebagai Upaya Percepatan Reduksi Sampah Buah dan Sayuran

Abstract

Black Soldier Fly (BSF) larvae treatment is one of the organic waste processing alternatives considered to have a faster process than the other organic waste processes. However, in solid organic waste processing, BSF larvae ability to reduce organic waste is relatively low. This research aims to know the optimum waste reduction index of fruit and vegetable waste with the feed modification of fruits and vegetables' waste, analyze the Efficiency of Conversion of Digested food of BSF larvae, and know the survival rate of BSF larvae. This research used an experimental method with four reactors containing 200 larvae on each reactor. Larvae used in this research were aged 7-18 days. A different larva is fed to each reactor with rate of 100mg/larva per day. The feed are vegetables, steamed vegetables, fruit, and fermented fruit. The frequency of feeding was once a day, and weight reduction from the treatment was measured daily. Reduction results in the vegetable waste, steamed vegetables, fruit, fermented fruit were 45.29%, 42.92%, 33.75%, and 46.25%, respectively. According to the results, the reduction of fruits and vegetables' waste using optimum BSF larvae reached 46.25% in fermented fruit feed treatment. Keywords: BSF larvae, reduction, organic waste, fruit waste, modification ABSTRAK Larva Black Soldier Fly (BSF) merupakan salah satu alternatif pengolahan sampah organik yang dinilai lebih cepat daripada pengolah sampah organik lainnya. Namun dalam pengolahan sampah organik yang padat, kemampuan larva BSF dalam mereduksi sampah organik cukup rendah. Penelitian ini bertujuan untuk mengetahui reduksi optimum sampah organik buah dan sayuran dengan modifikasi komposisi umpan sampah buah dan sayuran, untuk menganalisis konversi pakan yang dapat dicerna larva BSF, dan mengetahui tingkat keberhasilan hidup larva BSF. Penelitian ini menggunakan metode eksperimental menggunakan empat reaktor yang berisi 200 ekor larva pada setiap reaktornya. Larva yang digunakan dalam penelitian ini berumur 7-18 hari. Setiap reaktor diberikan umpan larva yang berbeda dengan laju pengumpanan 100mg/larva per hari. Umpan tersebut, di antaranya sayuran, sayuran dikukus, buah, dan buah difermentasi. Frekuensi pemberian umpan dilakukan satu hari sekali dan pengurangan berat umpan dari perlakukan yang diberikan diukur setiap hari. Hasil reduksi pada sampah sayuran, sayuran dikukus, buah, buah difermentasi masing-masing: 45,29%, 42,92%, 33,75%, dan 46,25%. Berdasarkan hasil tersebut, reduksi sampah organik buah dan sayuran dengan larva BSF optimum, mencapai 46,25% pada perlakuan umpan buah fermentasi.

Effect of Variations in the Pretreatment of Organic Waste on The Growth of Black Soldier Flies (BSF) Larval

“…In addition, photosynthetic bacteria in fermenting local microorganisms will accelerate decay and produce amino acids that can degrade dietary fiber and nutrients in feed so that protein can be easily absorbed by BSF larvae. Another function of amino acids is to produce antimicrobial substances from actinomycetes bacteria in fermentation, thereby increasing the palatability of larvae in consuming the given feed (Rofi et al, 2021). The results of other studies show maggot flour contains crude protein ranging from 28.2 -42.5% , 43.2% (Nguyen et al, 2015), while the results of the study used oil palm cake media, protein content is 44.01% (Rachmawati et al, 2015).…”

“…It means the high and low protein content of larvae is influenced by differences in the growing media used. Fermented fruit has the highest percentage of WRI value because the feed given has been overhauled by local microorganisms so that the fermented fruit has a soft texture (Rofi et al, 2021).…”

Mortality, Development and Nutrient Content of Black Soldier Fly Larvae (Hermetia illucens L.) Maintained on Different Types of Household Organic Waste

“…Therefore, the nutritional quality and availability of fulfilled larvae feed is essential to support the continuity of its phase of life and the optimal nutritional quality of the larvae. The composition of vegetable waste feeding is more than animal protein waste because vegetable waste includes organic waste that is more easily degraded or easily decomposed by BSF larvae [15]. Increasing the length and width of the body of BSF larvae before entering the prepupa phase, the larvae will meet the needs of growth and also nutrient content because it will have a physiological impact on the next phase until it becomes an imago and then lays eggs [16].…”

Pengaruh Penambahan Bioaktivator EM-4 Dan Mol Terhadap Laju Reduksi Sampah Organik Oleh Larva BSF

“…Sampah organik campuran dicacah kemudian selanjutnya di fermentasi dengan bioakivator EM-4 dan MOL selama 3 hari. Proses fermentasi ini dilakukan dengan tujuan untuk melunakkkan sampah organik campuran yang bersifat kasar dan keras (Rofi et al, 2021) Berdasarkan hasil penelitian Tabel.1 Pada penambahan EM-4 laju reduksi sampah organik oleh larva black soldier fly tertinggi adalah V2 (sampel sampah penambahan EM-4 30 ml) diperoleh laju reduksi sebesar 93 gr/hari. Apabila dibandingkan dengan kontrol memiliki laju reduksi 56gr/hari, maka perlakuan dengan menambahkan EM-4 30 ml mampu mempercepat laju reduksi lebih besar yaitu 37 gr/hari .…”
