Dano, IbnulRifa`i (2014) Pengaruh Pemberian Biosurfaktan Asal Pseudomonas Sp. Media Limbah Minyak Goreng Terhadap Kadar Total Suspended Solids (TSS) Dan Lemak Pada Limbah Cair Rumah Potong Ayam (RPA) Tradisional. Sarjana thesis, Universitas Brawijaya.

Indonesian Abstract

Rumah Potong Ayam (RPA) merupakan industri peternakan yang memiliki peran penting dalam mencukupi kebutuhan protein hewani masyarakat, tetapi berdampak negatif menimbulkan limbah yang mencemari lingkungan jika tidak dilakukan penanganan limbah dengan benar. Limbah dapat ditangani dengan bahan surfaktan sintetis maupun berasal dari mikroorganisme yang disebut biosurfaktan. Pseudomonas sp. merupakan mikroorganisme penghasil biosurfaktan. Penelitian ini bertujuan untuk mengetahui potensi biosurfaktan asal Pseudomonas sp. yang ditumbuhkan pada limbah minyak goreng dan pengaruhnya terhadap kadar Total Suspended Solid (TSS) dan lemak pada bioremediasi limbah cair RPA tradisional. Biosurfaktan diproduksi menggunakan media limbah minyak goreng dengan variasi kosentrasi (0%, 10%, 20%, 30% dan 40%) dan variasi waktu inkubasi (24 jam, 48 jam, 72 jam) dan diuji kualitasnya dengan uji drop collaps dan uji emulsifikasi. Pengujian biosurfaktan pada limbah cair RPA dengan variasi konsentrasi biosurfaktan (0%, 10%, 20%, 30%) dan variasi waktu inkubasi (24 jam dan 48 jam), dan dilakukan pengamatan terhadap penurunan kadar TSS dan lemak pada limbah cair RPA dengan metode gravimetri. Hasil penelitian menunjukkan biosurfaktan terbaik asal Pseudomonas sp. dihasilkan pada konsentrasi limbah minyak goreng 30% dan lama inkubasi 48 jam dengan nilai emulsifikasi sebesar 0,6 dan mampu menurunkan tegangan permukaan selama 1 detik. Biosurfaktan tersebut mampu menurunkan kadar TSS sebesar 0,013% dari kontrol 0,032% sedangkan kadar lemak sebesar 0,025% jika dibandingkan dengan kontrol sebesar 0,036%.

English Abstract

Poultry Slaughterhouse is a livestock industry that has an important role to fulfill animal protein for the community, but the negative impacts can lead to environmental pollution if not handling properly. Waste material can be treated with synthetic surfactant or surfactant from a microorganism which called biosurfactants Pseudomonas sp. is biosurfactant producing microorganisms. The aim of this study was to determine the potential of biosurfactan origins from Pseudomonas sp. and its effect on levels of Total Suspended Solid (TSS) and fat level in traditional poultry slaughterhouse liquid waste bioremediation. Biosurfactant were produced by using waste of cooking oil media with variation of concentration, that were (0%, 10 %, 20 %, 30 % and 40 % ) and variation of the incubation time were ( 24 h, 48 h, 72 h) that tested then by drop collaps test and emulsification test. Testing biosurfactant on slaughterhouse liquid waste with variations of biosurfactant concentration (0%, 10%, 20% and 30%) and incubation periods 24 h and 48 h and carried out observations of decreased levels of TSS and fats on liquid waste with the gravimetry methods. The results showed that the best biosurfactant were produced on the 30% concentration of cooking oil waste and in 48 hour incubation with emulsification value 0.6 and was able to low the surface tension on 1 second. Biosurfactant origins from Pseudomonas sp. could reduce TSS levels at 0.013% from 0.032% of control and lipid levels at 0.025% compared to control 0.036%.
