ABSTRAK   Jerami adalah limbah tanaman padi yang dapat digunakan sebagai bahan pakan ternak. Agar jerami tidak mengalami pembusukan, maka dilakukan proses fermentasi. Fermentasi merupakan proses pengubahan suatu zat dengan bantuan mikroorganisme dengan menghasilkan karbohidrat.  Fermentasi divariasikan dengan waktu 7, 15 dan 21 hari menggunakan probiotik EM4 dan starbio. Rasio perbandingan bahan jerami dan probiotik yaitu 10:1. Dilakukan pengamatan pada hasil fermentasi untuk kandungan protein, karbohidrat sederhana, dan kadar air. Hasil penelitian menunjukkan bahwa jerami hasil fementasi berwarna cokelat, kadar protein dan glukosa meningkat. Kadar protein dengan penambahan probiotik EM4 naik dari 5,775% menjadi 18,06% dan penambahan starbio menaikkan kadar protein menjadi 14,07%. Fermentasi jerami dengan penambahan EM4 lebih efektif daripada starbio. Waktu fermentasi yang paling efektif adalah 15 hari.   Kata kunci: Jerami, fermentasi, probiotik, EM4, starbio   ABSTRACT   Straw is rice crop waste which can be used as animal feed materials. To avoid straw to decay, the fermentation process is carried out. Fermentation is the process of changing a substance with the help of microorganisms to produce carbohydrates. Fermentation was varied for 7, 15 and 21 days using EM4 and starbio probiotics. The ratio of straw and probiotic is 10: 1. The results of fermentation were observed for protein, simple carbohydrates, and water content. The results showed that fermentation resulted in brown colour and icreases of protein and glucose levels. Protein levels with the addition of EM4 probiotics increase from 5.775% to 18.06% and addition of starbio increases the protein levels to 14.07%. Straw fermentation with the addition of EM4 is more effective than starbio. The most effective fermentation time is 15 days.   Keywords: Straw, fermentation, probiotics, EM4, starbio,

Research on fermentation time and the addition of milk powder to egg albumen is still limited. The purpose of this study was to determine the antioxidant activity and chemical characteristics of fermented egg albumen using different levels of full cream milk powder and different microbial fermentation times. This study used a completely randomized factorial pattern design, 4 x 5 treatments with 4 replications. Research materials include egg albumen, full cream milk powder and mixed Lactic Acid Bacteria (L. bulgaricus, L.achidopillus, and Streptococcus thermopillus). The research treatments were the addition of powdered milk in different level (%) including, 0, 2, 4 and 6. Fermentation times were 0, 12, 24, 36, and 48 h, respectively. The results showed that the addition of powdered milk in different level and fermentation time had no significant effect on the antioxidant activity. The addition of different-level powdered milk was not significant on the glucose content and total protein, but it was very significant (P<0.01) on water content. The fermentation time had a very significant effect (P<0.01) on glucose levels and total protein, but it had no significant effect on the water content of albumen fermentation. Antioxidant activity did not change during the fermentation time and the addition of different-level milk powder. The 24 h fermentation time could reduce the total protein and glucose levels of egg albumen. Adding 2% milk powder could reduce the water content of egg albumen fermentation.

Microbiological Characteristics

In addition to soybean, Leucaena leucocephala is one of the tempe raw materials usually used in Indonesia. These tempe is only made by peoples in a few areas in the southern part of Java such as Wonogiri, Gunungkidul and Pacitan. For some purposes, such as cooking ingredients, tempe is deliberately fermented longer than usual to obtain a savory taste. In a previous study, we had studied leucaena tempe or people known as lamtoro tempe that process in Wonogiri and reported that there had been a change in characteristic during fermentation until over-fermented tempe. Therefore, in this research, we analyzed the change in the chemical and microbiological characteristic of lamtoro tempe from Pacitan during continued fermentation. This research showed that during the fermentation process, mold, yeast, and lactic acid bacteria (LAB) persisted for up to 126 hrs of fermentation time. The growth of yeast and mold tend to decrease while LAB continued to increase until it reached 11 log CFU/mL. In addition, the moisture content, ash content, soluble protein levels, pH and titrated acid increased during continued fermentation time. Glutamic acid and aspartic acid were the highest amino acids by weight percentage. Both amino acids have an important role in the sensory characteristics of lamtoro tempe.

Sugar Cane Filter Cake (SGFC) is the sugar cane to sugar processing waste in Krebet Baru Sugar Factory. Utilization of this SGFC waste was limited for free soil or unprocessed fertilizer. Sugar cane filter cake is an organic waste which potential to be utilized into biogas. Biogas is anaerobic process product which consist methane as a major compound. Factors that influence biogas fermentation process were temperature, water content, fiber, total sugar and total concentration of methanogen bacteria inoculum. Natural source of methanogenic bacteria is in the contents of the cattle rumen. The aim of this study was to determine the characteristics of blotong and the effect of addition of cattle rumen on biogas fermentation from the SGFC of the Krebet Sugar Factory. The first stage of this research was Blotong characterization. The second stage was spontaneous fermentation with two treatment factors. The first factor was enhancing the contents of the cattle rumen (5%) and without the addition of cattle rumen (0%). The second factor is the fermentation time with 3 different levels (20, 25 and 30 days). The results were shown that blotong had water content, fiber content, and C / N ratio were 10.71%; 0.06%; and 17: , respectively. These results indicate the potential of the blotong as a raw material for biogas production. SGFC fermentation with the addition of 5% cattle rumen content was shown the best results compared to biogas production with pure SGFC. The highest volume and yield of biogas produced were obtained from the 30-day fermentation process with the results of 37,327 ml of gas and 746.5 x 10-6 m3/kg. All flame tests show positive results and are proven to produce blue flames.

The oat β-glucan (OG) was added into set-type yogurt as a functional ingredient, in order to evaluate effects on the rheological characteristics and microstructure of set-type yogurt. When the OG concentration increased from 0 to 0.3%, the WHC gradually increased. At 0.3% OG, the set-type yogurt had the highest WHC of 94.67%. Additionally, the WHC continuously decreased, reaching the lowest WHC (about 80%) at 0.5% OG. When 0.3% OG was added, the highest score of sensory evaluation was about 85. The rheological result showed that the fermentation process went through the changes as follows: solid → liquid → solid → liquid. The addition of 0.3% OG decreased the fermentation time of set-type yogurt by about 16 min, making yogurt more inclined to be liquid. The acidity of set-type yogurt with OG was slightly higher. The result of microstructure showed that the addition of OG destroyed the three-dimensional network structure of yogurt, and some spherical aggregate particles could be clearly observed at 0.3% OG. Overall, this study provided a theoretical basis for the application of OG in set-type yogurt.

ABSTRACT ‘Babassu’ mesocarp flour has been used by the pharmaceutical, human food and animal feed industries. However, there is lack of standardization in the production, as well as absence of information on the management of the product’s quality. Thus, the objective of this study was to dry the ‘babassu’ mesocarp in forced-air oven and solar dryer, adjust different mathematical models to the experimental data, as well as to quantify the levels of proteins and crude fiber of the produced flour. The criteria for the adjustment were the coefficient of determination, magnitude of the mean relative error, standard deviation of estimate and the residual distribution trend. Drying in the shortest time occurred in oven at 60 °C (370 min), leading to water content of 4.62%, while in the solar dryer the final water content was 8.07% in 6 days. The mathematical model Two Terms showed the best fit to the experimental data for oven drying and the Midilli model showed the best fit in solar dryer. There was an increase in protein content with the drying in solar dryer and oven at 40, 50 and 60 °C (1.36, 1.33, 1.15 and 1.37%, respectively) in relation to fresh mesocarp (0.88%). Drying in both oven and solar dryer promoted increase of protein in the flour.

Pulp degradation during cocoa fermentation can be carried out by depolymerization process of pulp pectin using endogenous pectolytic enzymes at optimum condition. The objectives of this research were to study the effect of fermentation process based on optimum condition in terms of temperature and pH of pulp pectin depolymerization using endogenous pectolytic enzymes polygalakturonase (PG) and pectin metyl esterase (PME) and fermentation period in cocoa processing on quality characteristics of cocoa beans produced and to study the role of those fermentation process in reducing fermentation time to produce cocoa beans with standard quality. This research used split plot design, with treatments of process condition of cocoa fermentation as main plot and fermentation period as split plot. Treatment of process condition of cocoa fermentation consisted of optimum condition for pulp pectin depolymerization by PGs (temperature 47.5OC; initial pulp pH 4.6); optimum condition of depolymerization on sequence depolymerization by PGs (temperature 48.5OC; initial pulp pH 8.0 during 1 day; last temperature 47.5OC; initial pulp pH 4.6 during 6 days), and natural fermentation process a control. While treatment of fermentation period consisted of 0, 1, 2, 3, 4, 5, 6 and 7 days. Evaluation of fermentation period was carried out based on pursuant to criteria of unfermented beans content and fermentation index. The results showed that process condition and fermentation time of cocoa affected quality characteristic of cocoa beans produced. Period of cocoa fermentation process based on optimum condition for pulp pectin depolymerization using endogenous pectolytic enzymes was 2 days shorter compared to natural fermentation. Cocoa beans quality of grade I and II were obtained from fermentation time of 4 and 2 days, respectively, using fermentation process based on optimum condition of pulp pectin depolymerization using endogenous pectolytic enzymes, whereas 6 and 4 days, respectively, when using natural fermentation.Key words: cocoa quality, fermentation, depolymerization, pectolytic.
