Abstract

Rice straw and cassava waste are abundant agricultural byproducts, but they have limitations in nutritional value, particularly low protein content. This study aims to evaluate the effect of a combination of straw and cassava substrates, as well as the addition of Saccharomyces cerevisiae mold, on increasing the content of single cell protein (SCP), crude protein, pure protein, microbial biomass, and pH stability during fermentation. The study was conducted experimentally with a 2×2 factorial completely randomized design (CRD) using four treatments: JKN (straw + cassava peel without yeast), JKR (straw + cassava peel + yeast), JSN (straw + cassava without yeast), and JSR (straw + cassava + yeast). Fermentation was carried out for 7 days under anaerobic conditions. The results showed that the JSR treatment produced the highest SCP (47.59 mg/mL) and the largest microbial biomass (4.37 mg/mL), while JSN produced the highest crude protein (13,40%) and pure protein (9,61%). The addition of yeast significantly increased PST and biomass, but in some treatments, it decreased the pure protein content. The combination of straw and cassava has been shown to increase the nutritional value of feed ingredients through the fermentation process, with effectiveness depending on the type of substrate and the presence of microbial inoculum.

Abstract

Penelitian ini bertujuan untuk menguji karakteristik, kandungan serat kasar dan protein kasar sabut kelapa muda fermentasi menggunakan 3 jenis bioaktivator. Bahan yang di gunakan yaitu limbah sabut kelapa muda, EM4, ragi tempe, ragi tape (Saccharomyces cerevisiae) dan molases. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 ulangan yaitu P0 (sabut kelapa + molasses), P1 (sabut kelapa + molasses + EM4), P2 (sabut kelapa + molasses + ragi tape (Saccharomyces cerevisiae), P3 (sabut kelapa + molasses + ragi tempe (Rhizopus oligosporus). Data yang diperoleh berdasarkan analisis hasil sidik ragam menunjukkan bahwa karakteristik sabut kelapa muda fermentasi penggunaan bioaktivator berbeda tidak memberikan pengaruh yang signifikan terhadap aroma, tektur, warna, kelembapan, kehadiran jamur, pH, temperatur. Berdasarkan analisis proksimat AOAC 2005 dan analisis vansoes 1990 didapatkan hasil bahwa pemberian bioaktivator berbeda tidak berpengaruh terhadap karakteristik sabut kelapa muda fermentasi. Perlakuan bioaktivator terbaik adalah ragi tempe (P3) karena mampu menurunkan kandungan SK dan NDF sabut kelapa muda.
