Abstract

Brachiaria decumbens grass is a high-quality forage that can grow well in tropical regions and has great potential in improving the efficiency of ruminant livestock production. This research aims to determine the effect of rabbit manure fertilizer on the physical quality and Total Digestible Nutrients (TDN) content of Brachiaria decumbens grass, as well as to determine the best dosage for its application. The research was conducted using a Randomized Block Design (RBD) with five treatments: P0 (without fertilizer), P1 (10 tons/ha), P2 (20 tons/ha), P3 (30 tons/ha), and P4 (40 tons/ha), each with three replications. The observed variables included bulk density, water solubility, water absorption, TDN, and gross energy. The analysis results showed that the application of rabbit manure fertilizer had a very significant effect (P<0.01) on water solubility and water absorption, and a significant effect (P<0.05) on bulk density. Treatment P4 produced the best values with the lowest bulk density (231.28 g/cm³), highest water absorption (10.47%), and lowest water solubility (25.51%). Although the TDN and gross energy values were not significantly different (P>0.05), both showed an increasing trend, reaching 24.34% and 3.61 kcal/g respectively in treatment P4. These results indicate that the application of rabbit manure fertilizer can improve the physical quality and tends to increase the nutritional value of the grass. A dosage of 40 tons/ha is recommended as the optimal treatment for sustainable cultivation of Brachiaria decumbens grass

Abstract

Bede grass (Brachiaria decumbens) is a plant that has good quality for green fodder. This can be seen from the growth rate, production and nutritional content contained therein. This study aims to determine the effect of providing solid organic fertilizer on the growth of Bede grass (Brachiaria decumbens) and to determine the effect of providing solid organic fertilizer with different doses on the growth of Bede grass (Brachiaria decumbens). The design used in this study was a randomized block design (RAK) with 5 treatments and 3 replications. The treatments used were P0 = Grass without providing solid organic fertilizer, P1 = Grass with providing 10 tons/ha of solid organic fertilizer, P2 = Grass with providing 20 tons/ha of solid organic fertilizer, P3 = Grass with providing 30 tons/ha of solid organic fertilizer, P4 = Grass with providing 40 tons/ha of solid organic fertilizer. From the results of the study, the provision of solid organic fertilizer had no significant effect (P>0.05) on all growth and production parameters of Bede grass (Brachiaria decum bens), except for the production of fresh leaf weight, which showed a significantly different effect (P<0.05). This shows that the application of solid organic fertilizer with various doses has not provided a significant effect on the vegetative growth of plants. The provision of solid organic fertilizer with different doses did not have a significant effect (P>0.05) on the growth of Brachiaria decumbens. However, the provision of solid organic fertilizer with a dose of 30 tons/ha has the potential to provide the best growth and production results compared to other doses. The researcher suggests that further research is needed to take into account environmental factors such as light intensity and soil conditions to better understand the effect of solid organic fertilizer on Bede grass (Brachiaria decumbens) and the use of a dose of solid organic fertilizer of 30 tons/ha can be considered because it shows a tendency for the best results even though it has no significant effect.

Abstract

The high cost of feed and the demand for increased production efficiency in the super village chicken farming business encourages the need for innovation in the use of environmentally friendly natural materials. Ecoenzymes, as a result of organic waste fermentation, have the potential to support digestive health and nutrient utilization so that they are expected to improve the growth performance of super village chickens. This study aims to determine how the provision of eco-enzymes in drinking water mixtures affects the growth of super village chickens aged 3-10 weeks and To determine at what level the provision of eco-enzymes in drinking water mixtures affects the growth of super village chickens aged 3-10 weeks. The design used in this study was a Completely Randomized Design (CRD) consisting of 5 treatments and 3 replications. The treatments used were E0 = Chickens without eco-enzyme in the drinking water mixture, E1 = Chickens given eco-enzyme in 20 ml of drinking water mixture, E2 = Chickens given eco-enzyme in 40 ml of drinking water mixture, E3 = Chickens given eco-enzyme in 60 ml of drinking water mixture and E4 = Chickens given eco-enzyme in 80 ml of drinking water mixture. The results showed that the provision of eco-enzyme in the drinking water mixture had no significant effect (P>0.05) on the initial body weight, weight gain, final body weight, ration consumption, and FCR value of super kampung chickens. However, the provision of eco-enzyme had a very significant effect (P<0.01) on drinking water consumption. Although statistically insignificant, there was a tendency for increased body weight gain and feed efficiency in treatments E3 and E4. It was concluded that the provision of eco-enzyme up to 80 ml in drinking water has not been able to significantly improve the growth performance of super kampung chickens at the age of 3–10 weeks.

Abstract

This community service activity is carried out as a form of academic contribution to enhance the knowledge and skills of the community, especially the Kelompok Ternak Amerta Sari in Kesiut Village, in processing and preserving local resources as alternatives for livestock feed, particularly for Bali cattle. The issues faced by farmers in this area include limited availability of fresh feed, especially during the dry season, and the suboptimal use of local feed materials such as straw, turi leaves, and other agricultural waste. Through this activity, the service team provides training and guidance in feed processing techniques such as fermentation, silage, and the production of complete feed based on local resources. The methods used include counseling, technical demonstrations, and hands-on practice together with the farmer group members. The results of this activity show an increase in the understanding and skills of the community in preserving and processing livestock feed.
