PENGARUH FERMENTASI  LIMBAH PADAT PENGOLAHAN BIOETANOL DARI SINGKONG (MANIHOT ESCULENTA) MENGGUNAKAN SACCHAROMYCES CEREVISIAE TERHADAP KANDUNGAN GIZI LIMBAH - Effect of Solid Waste Treatment Bioethanol Fermentation of Cassava (Manihot Esculenta) Use Saccharomyces Cerevisiae Change Nutrition Against Waste

AbstrakPengolahan bioetanol yang berbahan singkong menghasilkan limbah padat yang masih jarang dimanfaatkan dan berpotensi sebagai pakan ternak. Maka sebelum diberikan pada ternak perlu dilakukan proses pengolahan melalui fermentasi. Salah satu jamur yang memiliki kemampuan dalam proses fermentasi adalah Saccharomyces cerevisiae. Penelitian ini bertujuan untuk mengetahui peningkatan kandungan nutrien limbah padat pengolahan bioetanol dari singkong (Manihot esculenta) melalui fermentasi oleh Saccharomyces cerevisiae. Penelitian ini dilakukan dengan metode eksperimental menggunakan Rancangan Acak Lengkap (RAL) pola faktorial 3 x 3 dengan ulangan tiga kali dengan dosis inokulum (D) masing-masing D1 = 2g, D2 = 3g dan D3 = 4g. Hasil penelitian menunjukkan bahwa peningkatan protein bervariasi dari 2% menjadi 3,05% dan penurunan kandungan kadar serat hasil fermentasi bervariasi dari 2,12%-2,36%. Kandungan HCN mengalami penurunan yang sangat signifikan dari 16,06% menjadi 0,74%. Kesimpulan bahwa fermentasi limbah padat bioetanol dengan menggunakan Saccharomyces cerevisiae dapat meningkatkan protein, menurunkan serat dan kadar HCN.Kata kunci : fermentasi, Saccharomyces cerevisiae, limbah padat bioetanol.AbstractProcessing of bioethanol made from cassava produces solid waste that is still rarely used and potentially as fodder. Therefore, before it is given to the cattle, it needs to be processed through fermentation. One of the fungi that have the ability in the process of fermentation is Saccharomyces cerevisiae. This study aims to determine the increase of nutrient content of the waste bioethanol processing from cassava (Manihot esculenta) through fermentation by Saccharomyces cerevisiae. This research was conducted with an experimental method using Completely Randomized Design (CRD) 3 x 3 factorial with three replications with a dose of inoculum (SC) respectively SC1 = 2g, 3g and SC2 = SC3 = 4g;. The results shows that increasing the protein varies from 2% to 3,05% and decreased levels of fiber content of fermented varies from 2,12% - 2,36%. The content of HCN is decreased significantly from 16,06% to 0,74%. The conclusion that solid waste bioethanol fermentation using Saccharomyces cerevisiae can increase protein, fiber and lower levels of HCN.

Organic waste of public market is one of the problems that greatly impact public health. The technology of processing public market waste into compost is a very good alternative, yet how long does it take, to process into compost and any nutrient contained requires research on this matter, as well as its application to plants, in this case, agarwood. The method used in this study was the experimental method with the old treatment of compost formation, as well as its application to agarwood plant using a completely randomized design (CRD). The results showed that 28 days of composting contained nutrients in the form of ions which were more easily absorbed by plants compared to nutrient content at duration 7 days. This is supported by the application of compost, where the addition of compost is very influential on the height of agarwood. As such, compost from organic ingredients is very well applied to agarwood plant.

Waste vegetable of traditional market provided very abundant and rarely used. German mealworm known as giant meal worms are the larvae of insects named Zhopobas morio parent has a size larger than the hongkong mealworm. The purpose of this study was to determine the application of vegetable waste in feed media of German mealworm which has a different nutrient content. This experiment using a completely randomized design (CRD) factorial design with treatment G1P1 (GE 4000 kcal / kg, PK 10%), G1P2 (GE 4000 kcal / kg, PK 12%), G1P3 (GE 4000 kcal / kg, PK 14% ), G2P1 (GE 4500 kcal / kg, PK 10%), G2P2 (GE 4500 kcal / kg, PK 12%), G2P3 (GE 4500 kcal / kg, PK 14%), G3P1 (GE 5000 kcal / kg PK 10 %) G3P2 (GE 5000 kcal / kg PK 12%), G3P3 (GE 5000 kcal / kg PK 14%), each treatments replicated 3 times. The results of the research showed that the application of vegetable waste in german worm feed media is able to increase the use of feed concentrates containing gross energy and crude protein low. Vegetable waste treatment in feed media which containing gross energy of 4000 kcal / kg and 14% crude protein showing the highest value on dry matter feed intake, weight of the harvest, and worm weight gain.

The influence of rice straw fermentation using white rot fungi and saccharomyces cerevisiae supplementation on in vitro nutrient digestibilityABSTRACT. An experiment to investigate the effect of rice straw fermented using white rot fungi and Saccharomyces cerevisiae supplementation on nutrient digestibility In Vitro had been implemented in two phases. The first experiments undertaken to make rice straw fermentation, using experimental methods with a Completely Randomized Design. As the treatment were White rot fungi (Phanerochaete chrysosporium) 0, 5 and 10 g/kg of rice straw (DM basis). Each treatment was repeated six times, so there are 18 experimental units. The variables measured included nutrient content of rice straw. A second experiment carried out in vitro to test the best rice straw fermentation results of the first experiment, using experimental methods, with a Completely Randomized Design. As the treatment were the supplementation of Saccharomyces cerevisiae (0, 2, 4% of the weight of fermented rice straw, DM basis). The variables measured included digestibility of dry matter, organic matter, cellulose and lignin digestibility of feed containing fermented straw. The data obtained were analyzed using analysis of variance test followed by Orthogonal Polynomials. The results can be concluded that the fermented rice straw using Phanerochaete chrysosporium 10 g/kg of rice straw is the best nutrient content. Saccharomyces cerevisiae supplementation on feed that contains fermented rice straw using Phanerochaete chrysosporium 10 g/kg rice straw is 2%.

Tofu industrial waste has the potential to become contaminant when it is not maximum processed, so it needs appropriate treatment to minimize the occurrence of pollution. Î²-Glucans can be produced from the yeast cell wall of Saccharomyces cerevisiae.As a feed supplement, Î²-Glucans have been used for an immunostimulant because it can increase the immune system. This study aimed to establish a suitable technology to produce Î²-Glucans fromSaccharomyces cerevisiae by utilize tofu waste as feed supplement. The Completely Randomized Design (CRD) model was used in the experimental method. This study used an experimental method with a Completely Randomized Design (CRD) model.The treatment given wereP1: 1kg of tofu waste + 1kg of bran +0.2 kg fish meal + 0.2 lt molasses + 5.5 gSaccharomyces cerevisiae; P2: 1kg of tofu waste + 1kg of bran +0.2 kg fish meal + 0.2 lt molasses + 6.5 g Saccharomyces cerevisiae; P3: 1kg of tofu waste + 1kg bran + 0.2 kg fish meal +0.2 lt molasses + 7.5 g Saccharomyces cerevisiae. Each treatment was repeated 3 times, and fermented for five days.The results found that P1 by Saccharomyces cerevisiae 5.5 g was the best formulation to produced crude Î²-Glucans by weight of 25.9 g/kg of waste. Production of Î²-Glucans as an animal feed supplement is a waste-based feed technology development which is expected to increase livestock production both in quality and quantity.
