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

Penggunaan antibiotik dalam pakan pada ternak pada akhir – akhir ini menjadi permasalahan dalam dunia peternakan. Pemakaian antibiotik dapat menyebabkan residu pada ternak sehingga dapat menyerang sistem imunitas konsumen. Oleh karenanya diperlukan alternatif alami sebagai pengganti antibiotik dalam upaya pertumbuhan optimal pada broiler. Pengganti antibiotik yang digunakan yaitu fermentasi air nira. Fermentasi air nira menghasilkan probiotik alami yang juga menghasilkan BAL (bakteri asam laktat). Tujuan penelitian ini adalah melihat interaksi antara lama fermentasi air nira dan selang hari pemberian air nira untuk meningkatkan persentase karkas, menurunkan persentase lemak abdomen, dan kadar kolesterol daging broiler. Pemanfaatan fermentasi air nira dapat digunakan untuk broiler karena mengandung BAL (bakteri asam laktat) yang dapat memacu pertumbuhan bakteri yang menguntungkan serta mencegah bakteri pathogen didalam usus broiler. Selain itu, BAL (bakteri asam laktat) juga menghasilkan enzim BSH (bile salt hydrolase) yang mampu mendekonjugasi garam empedu yang akan diserap oleh usus dan enzim lipase yang memiliki fungsi sebagai pemutus lemak dan menurunkan kadar kolesterol daging pada broiler.
