The aim of this study was to evaluate water spinach as forage substitution on in vitro gas production, digestibility and kinetics fermentation. The experiment was arranged in a completely randomized design with four treatments and five replications. The Treatments were: T1 = control of Pennisetum purpureum cv Mott grass + 0% of water spinach, T2 = + 20% of water spinach, T3: 40% of water spinach and T4: 60% of water spinach. Results showed that substitution of 20% Water Spinach as forage increased gas production after 48 h of incubation. There is no difference in the potential fraction degraded by the addition of a water spinach at the level of 20% compared to the control, although there is a decrease in the addition of 40 and 60% of the water spinach. Substitution of water spinach was not significant on kinetics fermentation of readily soluble fraction (a) and rate constant per hour of gas production (c). The substitution of 20% water spinach increased dry matter digestibility reaching 10% compared to control. The water spinach substitution increased organic matter digestibility (P<0.05). It is concluded that 20% of water spinach had the highest gas production and nutrient digestibility and thus, it can be used as forage alternative for ruminant.
This study aims to sup determine the utilization of water spinach as a substitute for forage sources, digestibility, and feed degradation. Klaten Regency is one of the producers of water spinach that has the potential to be developed as the center for producing the largest water spinach at the regional level and has a role as one of supporting the needs of ruminant animal feed at regional and regional levels during the dry season. The method used is a survey, sampling technique with stratified random sampling. The conclusion of the results of this study is the total supply of the use of water spinach reached the level of 20% resulting in higher total gas production, although it did not show a significant difference in VFA digestibility and production in vitro compared to the control. Feed digestibility increased with the addition of water spinach in a feed with a productivity average of 2.05 tons/ha of 3,947 ha of land area. The scheme (chain) of the supply of dried water spinach straw material is 41.25% for privately owned ruminants, and 58.75% is sold to middlemen by being sold to farmers outside the Klaten Regency area.
The relatively high-volume of vegetable waste in the Special Region of Yogyakarta Province causes environmental problems. Although it contains high nutrients, vegetable waste potential as ruminant feed is yet optimally utilized due to the possible presence of heavy metals such as Pb, Cu, and Hg, which can reduce livestock productivity. This study aimed to determine the nutrients and heavy metals content of vegetable waste from 11 traditional markets in Yogyakarta. The results showed vegetable waste contains protein (>20%) and fiber (<30%). It was also noted that the heavy metal concentration is below the maximum tolerable limit for ruminant feed ingredients. The nutrient and heavy metal content showed no difference between Sleman District, Bantul District, and Jogja City. This study concludes that vegetable waste from traditional markets in the Special Region of Yogyakarta has prospective as ruminant feed due to its high nutrient content with a low level of heavy metal.
Arabica coffee (Coffea arabica L.) Java Preanger is the best coffee from West Java which is better known internationally as Java Preanger. One of the secondary metabolites found in Arabica coffee beans and efficacious as an antioxidant is chlorogenic acid. Lozenges were made by wet granulation method with various concentrations of coffee extract 5%, 10% and 15%. The resulting preparation was then evaluated for its physical and antioxidant activity. Physical evaluation includes organoleptic tests, weight uniformity, size uniformity, hardness, friability, frictionibility and disintegration time. Meanwhile, the antioxidant activity test was carried out using the ABTS method. Based on the results of the physical evaluation, the formulation that meets the requirements is formula 3 (F3) with a coffee bean extract concentration of 15% and has the highest antioxidant activity with an IC50 value of 27.915 ppm.
This study aims to prove the sauerkraut liquids in the drinking water of broiler chickens to weight gain, final weight, feed consumption, feed efficiency and the amount of lactic acid bacteria intestine of broilers. A total of 24 chickens broiler DOC with an average weight of 25-35 gr/tail. Broiler chickens were randomly divided into 4 groups.. Each group was given liquids sauerkraut 0 ml/L, 0.5 ml/L, 1.0 ml/L, and 1.5 ml/L in drinking water for 35 days. The results showed the treatment liquids concentration sauerkraut 1,5 ml/L in drinking water have a significant effect (P <0,05) on body weight gain, final weight, feed intake, feed efficiency and the amount of lactic acid bacteria intestines of broiler chickens. Average of body weight gain of broilers given liquids sauerkraut 1.5 ml/L in drinking water significantly (P <0.05) higher than the weight gain of broilers concentration 0 ml/L. Average of final weight of broilers given liquids sauerkraut 1,5 ml/L in drinking water significantly (P <0.05) higher than the final weight of broilers concentration 0 ml/L. Average of consumption of broiler chicken feed given liquids sauerkraut 1,5 ml/L significantly (P <0.05) lower than the consumption of broiler chicken feed concentration of 0 ml/L. Average of FCR of broilers given liquids sauerkraut 1,5 ml/L significantly (P <0.05) lower than the FCR of broilers concentration of 0 ml/L. The average amount of lactic acid bacteria intestines of broilers given liquids sauerkraut 1.5 ml/L significantly (P <0.05) higher than the amount of lactic acid bacteria intestines of broilers concentration of 0 ml/L. On the research that use of liquids sauerkraut in drinking water 1,5 ml/L can improve feed efficiency and amount of lactic acid bacteria broiler chicken intestines of 23.5%, and 19.4%. Keywords: Broiler chickens, sauerkraut, feed efficiency, the amount of lactic acid bacteria

An in vitro technique based on two stages of batch culture was used to clarify fermentability and digestibility of pellet feed containing water spinach (Ipomoea aquatica). The portion of Pennisetum purpureum in the pellet feed was substituted with Ipomoea aquatica at respective levels of 0% (T1), 20% (T2), 40% (T3) and 60% (T4). The treatments were allocated in a completely randomized design with 5 replicates of each. The results showed that the substitution of water spinach in pellet did not effect on pH, ammonia (NH 3), enzyme protein and microbial protein. Volatile Fatty Acids (VFA), acetate (C2), propionate (C3), butyrate (C4), methane (CH 4) and carbon dioxide (CO 2) were decreased (p<0.05) by water spinach substitution level in the treatments. The ratios of C2: C3 were increased (P<0.05) in both of T3 and T4. The increasing water spinach substitution level enhanced (p<0.05) dry matter digestibility and organic matter digestibility but crude fiber digestibility was unaffected. In conclusion, substitution of Pennisetum purpureum with Ipomoea aquatica at the level of 20% may be the best fiber source for ruminant diet.
