Abstract
Limbah organik merupakan jenis limbah terbanyak dengan jumlah 57%. Limbah tersebut berasal dari sisa hasil industri, sisa makanan, kayu, dan ranting. Biokonversi limbah organik dapat dilakukan dengan mengembangbiakan maggotBlack Soldier Fly (BSF) karenadapat mendegradasi 55% limbah. Lemak maggotBSF mempunyai kandungan ester asam laurat 23,4%, ester asam oleinat 27,1% dan ester palmitat 18,2% yang berpotensi sebagai bahan baku biodiesel. Penelitian ini menggunakan metode response surface method (RSM) central composite design (CCD) dengan dua faktor dan tiga variabel respon. Faktor yang digunakan yaitu rasio bahan:pelarut dengan level perlakuan 1:4, 1:6 dan 1:8 g/mL. Faktor kedua yang digunakan yaitu lama ekstraksi dengan level perlakuan 20, 40 dan 60 menit. Variabel respon yang digunakan adalah kadar asam lemak bebas (FFA), bilangan asam dan rendemen dengan batas sesuai SNI 7182:2015. Rasio bahan:pelarut mempunyai pengaruh yang signifikan terhadap kadar asam lemak bebas (FFA) dan bilangan asam lemak maggot BSF. Semakin banyak pelarut yang digunakan, maka akan semakin tinggi nilai dari respon tersebut. Lama waktu ekstraksi mempunyai pengaruh yang signifikan terhadap rendemen lemak maggot BSF. Semakin lama ekstraksi yang dilakukan, maka rendemen yang dihasilkan semakin besar apabila dilakukan dengan pelarut dengan tingkat kemurnian tinggi Solusi optimal dihasilkan dari level perlakuan rasio bahan:pelarut 1:4 g/mL dengan lama ekstraksi 20 menit. Hasil prediksi solusi optimal respon kadar asam lemak bebas (FFA) sebesar 3,03%, bilangan asam 6,01912 mg KOH/g, dan rendemen29,4923%. Hasil aktual yang dihasilkan dari validasi data masing-masing respon adalah 3,04%, 5,99 mg KOH/g dan 30,15%.
English Abstract
Organic waste is the largest type of waste with a total of 57%.The wastecomes from industrial waste, foodwaste, wood, and twigs. Bioconversion of organic waste can be done by breeding Black SoldierFly (BSF) maggots because it can degrade 55% of organic wast. BSF maggot fat has a 23,4% lauric acid ester, 27,1% oleinic acid ester and 18,2% palmitic ester which has the potential to be used as a raw material of biodiesel. This study used the response surface method (RSM) central composite design (CCD) with two factors and three response variables. The factorused is the ratio of the solvent to the treatment levels of 1:4, 1:6 and 1:8 g/mL. The second factor used is the extraction duration with treatment levels of 20.40 and 60 minutes. The response label used is the level of free fatty acids (FFA), acid numbers and yield with limits based on SNI 7182:2015. The ratio of solvents has a significant influence on the level of free fatty acids (FFA) and the number of BSF maggot fatty acids. The more solvents used, the higher value of the response. The length of extraction time has a significant effect on the fat yield of BSF maggots. The longer extraction is carried out greater the yield when done with high concentration solvent. The optimal solution result from the treatment level of the solvent ratio of 1:4 g/ml, and the extraction duration was 20 minutes. The predicted result of the optimal solution response of free fatty acid content (FFA) was 3.03%, the acid number was 6.01912 mg KOH/g and the yield was 29.4923% . The actual results from validation of the responses were 3.04%, 5.99 mg KOH/g and 30.15%.
