Abstract
Metode pengomposan menggunakan larva Black Soldier Fly (BSF) mampu menguraikan sampah organik hingga 70%-85%. Hal ini dapat menjadi salah satu alternatif dalam mengurangi besarnya timbulan sampah organik yang terus meningkat setiap tahunnya. Pemanfaatan Larva BSF dalam mendekomposisi sampah lebih efisien, karena tidak perlu memisahkan antara sampah hewani dengan nabati. Selain itu dapat dicampur dengan kotoran hewan dan manusia. Penelitian ini memiliki tiga tujuan yaitu menentukan kemampuan Larva BSF dalam mereduksi sampah organik, menentukan pengaruh variasi jenis sampah organik dan feeding rate terhadap pertumbuhan Larva BSF, menentukan karakteristik hasil dekomposisi sampah organik biodegradable yang dilakukan oleh Larva BSF. Penelitian ini dilakukan menggunakan Larva BSF usia 6 hari. Setiap reaktor terdapat 300 ekor larva. Adapun variasi dalam penelitian ini yaitu campuran jenis sampah dan feeding rate. Jenis campuran yang digunakan: 1) sampah sisa makanan dengan sampah sayur, 2) sampah sisa makanan dengan sampah buah, dan 3) sampah sisa makanan dengan sampah kebun. Feeding rate yang digunakan adalah 20 mg/larva/hari, 35 mg/larva/hari, 50 mg/larva/hari. Banyaknya feeding merupakan berat kering sampah. Penimbangan berat larva dilakukan setiap 3 hari sekali sesuai dengan waktu feeding. Pada akhir penelitian dilakukan pengukuran berat residu hasil dekomposisi sampah dan kualitasnya. Hasil penelitian menunjukkan tingkat reduksi untuk komposisi sampah sisa makanan dan sayur adalah 81,98% pada feeding rate 20 mg/larva/hari. Komposisi sisa makanan dan kebun memiliki tingkat reduksi sebesar 42,71% pada feeding rate 35 mg/larva/hari. Komposisi sisa makanan dan buah memiliki tingkat reduksi 81,23% pada feeding rate 35 mg/larva/hari. Tingkat pertambahan berat larva paling besar terjadi pada feeding rate 35 mg/larva/hari dengan komposisi sampah sisa makanan dan buah. Tingkat pertambahan berat mencapai 127,06 mg/larva dari berat larva awal. Kandungan protein larva pada sisa makanan dan sayuran dengan feeding 20 mg/larva/hari sebesar 34,94%. Campuran sisa makanan dan kebun dengan feeding 35 mg/larva/hari sebesar 44,35%. Campuran sisa makanan dan buah dengan feeding 35 mg/larva/hari sebesar 59,25%.

Using Compost method with Black Soldier Fly (BSF) larvae could decompose the organic waste around 70-85 percent. It could be one of the alternatives to decrease the emergence of garbage gradually. Utilization of BSF larva in decomposing was more efficient because it did not need to separate between animal or vegetable waste. Even, it could mix with the animal and human waste. This study had 3 purposes, there are to determine the BSF’s ability in reducing the organic waste, determain the influence of waste composition and feeding rate on larva growth rate, determine the charakteristics of the biodegradable organic waste decomposed by the BSF larvae. This research was conducted by using Black Soldier Fly (BSF) larva at the age of 6 days. Furthermore, adding some variations such as mixing the type of waste and feeding rate. Type mixing that used in this research included: 1) remaining food waste and vegetable, 2) remaining food waste and fruit 3) remaining food waste and garden waste. Feeding rate that used a day were 20 mg/larva, 35 mg/larva, 50 mg/larva. Much of feeding rate was weight of dry waste. The weighing larva was conducted once in 3 days that proper to the time weighing. At the last research, the writer conducted a weighting of the remaining waste as the result of decomposition waste and the quality. The result of this research showed that the reduction level for composition food and vegetable waste were 81.98 percent on feeding rate 20 mg/larva a day. Composition food and garden waste had a reduction level around 42.71 percent on feeding rate 35 mg/larva a day. Composition food and fruit waste had a reduction level around 81.23 percent on feeding rate 20 mg/larva a day. The biggest of the increasing weight of larva occurred on the feeding rate of 35 mg/larva a day with food and fruit waste composition. The increasing weight level reached around 127.06 mg/larva from initial weight. Protein content in the larva of food and vegetable waste with feeding 35 mg/larva day was 34.94 percent. Mixing food and garden waste with feeding 35 mg/larva a day was around 44.35 percent. Mixing food and fruit waste with feeding 35 mg/larva a day was around 59.25 percent.
