Abstract
Melimpahnya jumlah sampah organik memberikan kontribusi terhadap dampak lingkungan, di mana salah satunya adalah penyebab penghasil gas methane terbesar selain penyebab berbagai macam polusi lingkungan. Salah satu cara yang berpotensi untuk menguraikan limbah organik dengan metode yang ramah lingkungan adalah dengan menggunakan BSF (Black Soldier Fly). Terlebih lagi metode tersebut sangat cocok diaplikasikan pada daerah tropis seperti Indonesia. Dalam siklus hidup BSF ini memberikan banyak peluang untuk diaplikasikan. Fase II hingga III dapat dimanfaatkan untuk pengolahan sampah organik dan berpotensi juga sebagai bahan baku pakan ternak . Pada Fasa III dan IV terjadi pergantian kulit (shedding) larva. BSF dewasa (Imago) memiliki fase hidup relatif singkat. Dari setiap fase-fase tersebut akan menghasilkan limbah organik yang memiliki kandungan kitin di dalamnya. Kitin ini dapat diolah menjadi kitosan sebagai hasil turunannya. Alternatif metode yang digunakan dengan menggunakan gelombang mikro yang ramah lingkungan berdasarkan variasi daya dan ukuran serbuk limbah BSF yaiitu : prepupa, pupa dan imago. Yield kitosan terhadap kitin mencapai 94-100%. Berdasarkan hasil FTIR (Fourier Transform Infrared Spectroscopy) menunjukkan bahwa terjadi proses deasetilasi maksimal pada daya 720 watt dan ukuran serbuk 112 μm yang menghasilkan DD (Derajat Deasetilasi) sebesar 78 – 80%. TGA/DSC memperlihatkan tahapan dekomposisi kitosan dipengaruhi temperature. Kandungan air dalam kitosan berada pada range 0-10%. Kandungan abu berada pada range 40-25%, kecuali pada imago pada range 45-50%. Temperatur dekomposisi tertinggi ditunjukkan oleh prepupa dan pupa pada range 690-725°C, sedangkan imago sekitar 340 °C. Kemampuan anti bakteri dalam membunuh bakteri 77%, 53%, dan 40% pada prepupa, pupa, imago.

The abundant amount of organic waste contributes to the environmental impact, where one of them is the biggest cause of methane gas producer besides causing various kinds of environmental pollution. One potential way to decompose organic waste with environmentally friendly methods is to use BSF (Black Soldier Fly). Moreover, this method is very suitable to be applied in tropical regions like Indonesia. In this BSF life cycle it provides many opportunities to be applied. Phases II to III can be utilized for processing organic waste and potentially also as raw material for animal feed. In Phase III and IV the skin changes (shedding) of the larvae. Adult BSF (Imago) has a relatively short life phase. From each of these phases will produce organic waste that has chitin content in it. Chitin can be processed into chitosan as a result of its derivatives. Alternative methods used by using microwaves that are environmentally friendly based on variations in the power and size of BSF waste powder, namely: prepupa, pupa and imago. Chitosan yields are mostly produced from prepupa and pupae. Based on the results of FTIR (Fourier Transform Infrared Spectroscopy) shows that there is a good deacetylation process at 720 watts power and 112 μm powder size indicates the process of chitin derivatives. TGA / DSC shows the stages of chitosan decomposition affected by temperature. The water content in chitosan is in the range of 0-10%. Ash content is in the range of 4025%, except for imago in the range of 45-50%. The highest decomposition temperature was shown by prepupa and pupae in the range of 690-725 ° C, while imago around 340 ° C. Anti bacterial ability to kill bacteria in 77%, 53%, and 40% in prepupa, pupa, imago.
