Abstract

Rendahnya nilai recovery factor sampah organik biodegradable menunjukkan rendahnya upaya recycle maupun recovery terhadap jenis sampah tersebut. Berbagai alternatif pengolahan sampah organik biodegradable telah dikembangkan. Salah satunya adalah dengan pemanfaatan larva Black Soldier Fly (BSF). Tujuan penelitian ini yaitu: (1) menentukan kemampuan larva BSF dalam mereduksi sampah organik biodegradable; (2) menentukan pengaruh jenis makanan dan frekuensi feeding terhadap tingkat pertumbuhan larva; (3) menentukan karakteristik residu dekomposisi larva BSF. Penelitian dilakukan dengan menggunakan larva BSF berumur 7 hari. Sebanyak 200 larva ditempatkan dalam kandang plastik dengan volume 1 L untuk setiap perlakuan feeding. Variabel penelitian meliputi variasi jenis makanan dan frekuensi feeding. Jenis makanan yang diberikan adalah sampah kantin, sampah pisang, dan sampah mentimun. Porsi makanan yang diberikan yaitu rata-rata 40 mg (berat kering)/larva.hari. Frekuensi feeding yang digunakan adalah sekali dalam sehari dan sekali dalam 3 hari. Berat 10% larva diukur setiap 3 hari. Pada akhir penelitian dilakukan pengukuran berat residu dekomposisi sampah dan kualitasnya. Tingkat penyisihan sampah mentimun, sampah kantin, dan sampah pisang masing-masing 54%; 54%; 52% pada frekuensi feeding sekali dalam tiga hari. Pada frekuensi feeding sekali dalam sehari diperoleh hasil masing-masing 52%;65%; 61%. Hanya jenis sampah makanan yang memberikan pengaruh signifikan terhadap pertumbuhan larva (P<0.1). Rasio C/N residu sampah mentimun, sampah kantin, dan sampah pisang adalah masing-masing 9,8; 11,1; dan 10,9 untuk frekuensi feeding sekali ii dalam tiga hari, dan masing-masing 8,0; 9,4; dan 10,0 pada frekuensi feeding sekali dalam sehari. Kadar air pada residu sampah mentimun, sampah kantin, dan sampah pisang adalah masing-masing 98,1%; 75,7%; dan 78,0% pada frekuensi feeding sekali dalam tiga hari dan masing-masing 97,9%; 73,6%; dan 81,7% pada frekuensi feeding sekali. Nilai pH dari residu sampah mentimun, sampah kantin, dan sampah pisang adalah masingmasing 5,54; 4,21; dan 4,18 untuk frekuensi feeding sekali dalam tiga hari, dan masing-masing 5.47; 5,00; dan 4,16 untuk frekuensi feeding sekali dalam sehari. ==================================================================================================== The lack of recycling and recovery program implementation of biodegradable organic solid waste has caused the low value of recovery factor. Various process options for treating this solid waste have been developed. One of the options is the use of black soldier fly (BSF) larvae. The objectives of this research are: (1) to determine the ability of the BSF larvae in reducing the organic biodegradable waste; (2) to determine the influence of food types and feeding frequency on the larval growth; and (3) to determine the characteristics of the residual material. This research was done using BSF larvae of 7 day old. Two hundred larvae were used for every feeding treatment, and placed in a growing cage. The feed types and feeding frequencies were varied. The feed types were three different food waste materials, which mainly composed of cucumber, banana, and canteen’s waste. The larvae were fed with 40 mg dry weight food waste/larvae.day. The feeding frequency was varied to once per day and once in three day periods. The weight of 10% of larvae per feeding treatment was measured every three days. At the end of experiment, the residual feed material and characteristics were measured. The removal efficiencies of cucumber waste, canteen waste, and banana waste in the feeding frequency of once in 3 days were 54%; 54%; 52% respectively. Accordingly, those of the feeding frequency of once per day were 52%;65%; 61% respectively. Only the food waste type showed significant influence (P<0.1) to the larval growth. The final C/N ratios of the cucumber waste, canteen waste, and banana waste were 9.8, 11.1, and 10.9 respectively for the feeding frequency of feeding frequency of once in 3 days; and 8.0, 9.4, 10.0 respectively in the feeding frequency of once in a day. The final water contents of iv these residual materials were 98.1%, 75.7%, and 78.0% in the feeding frequency of once in 3 days; and 97.9%, 73.6%, and 81.7% in the feeding frequency once per day. The final pH values of similar residual materials were 5.54, 4.21, and 4.18 in the feeding frequency of once in 3 days and 5.47, 5.00, and 4.16 in the feeding frequency of once per day.
