Abstract

By-products from oil palm can feed ruminants such as palm fronds (OPF) and palm oil sludge (PS). Judging from its continuous, cheap, and abundant availability from the palm oil industry, as well as a source of fiber or a component in complete feed for ruminants, it is the potential that can be used as animal feed. However, the use of oil palm fronds in livestock production is minimal due to their complex fiber structure, high lignin content, and low protein content. So, it needs management technology on OPF. The design used was a Completely Randomized Design (CRD) with three treatments and five repetitions: P0 Palm frond silage (30%) + palm sludge (70%) P1 Silage of palm fronds (30%) + palm sludge (70%) + Mineral Mix 1% P2Palm frond silage (30%) + palm sludge (70%) + Mineral Mix 2%. The data obtained were analyzed for variance according to the design used, and if there were differences between the treatments, continued analysis using the Duncan Multi Range Test Based on the results of statistical analysis showed that the silage treatment of palm frond powder and palm sludge supplemented with a mineral mix in vitro decreased the digestibility value of dry matter (P<0.05). However, different results were shown in the digestibility of organic matter, where increased digestibility occurred in treatment with supplementation of mineral mixes. The statistical analysis showed that the silage treatment of palm frond powder and palm sludge supplemented with the mineral mix in vitro showed no significant difference between treatments (P>0.05) on VFA and NH3 values. Based on the study's results, it can be concluded that mineral mix supplementation in the silage of palm frond powder and palm sludge significantly decreases the digestibility of dry matter but increases the digestibility value of organic matter. Nevertheless, the treatment given did not have a significant effect on the quality of the fermentation, which included VFA and NH3.

Abstract

Sakura Block Plus is a modification of Sakura Block, incorporating 6% earthworms and palm kernel cake as substitutes for corn. The objective of this study was to evaluate the supplementation of Sakura Block Plus in palm frond feed on the nutrient digestibility of beef cattle. The research design employed a Latin Square Design (LSD) with treatments P0 (10% Sakura Block Plus), P1 (8% Sakura Block Plus), P2 (10% Sakura Block Plus), and P3 (12% Sakura Block Plus).  Four male beef cattle, 18 months old, weighing approximately ± 110 kg, were utilized throughout four treatment periods, each lasting 15 days. The results of the study indicated a significant improvement in the 12% Sakura Block Plus treatment concerning the digestibility of Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), and hemicellulose. In conclusion, the supplementation of Sakura Block Plus at the 12% level in palm frond feed resulted in the most optimal nutrient digestibility.

Abstract

Mercury composite and cyanidation are gold mining methods that are frequently used. The mercury composite method produces tailings containing heavy metals that can harm living organisms. Utilisation of tailings for the development of forage may be enhanced through arbuscular mycorrhizal fungi (AMF) inoculation to increase plant resistance, absorption of macro and micronutrients, and reduce levels of metal contaminants in the tailings. This study aimed to investigate the effect of arbuscular mycorrhizal fungi on nutrients and heavy metals uptake by Pennisetum purpureum cv Mott in phytoremediation of gold mine tailings. Treatments consisted of four levels of AMF inoculation (0, 5, 10 and 15 g pot-1) were arranged in a completely randomised design with five replications. Each pot contained 3 kg of tailings. The results showed that the best crude protein, crude fiber, crude fat, Ca, and P contents in the plant shoots was obtained by providing AMF inoculation of 15 g pot-1. However, the treatment had no significant effect on dry weight, dry matter, and nitrogen-free extract. AMF significantly increased the uptake of heavy metals by the plant roots. The treatments did not significantly affect Pb uptake by plant roots and shoots and Hg uptake by plant shoots. AMF treatments significantly reduced the translocation factor (TF) value for Hg, bioconcentration factor (BCF) values for Cd and Pb, and removal efficiency (RE) values for Cd and Pb. AMF could effectively increase nutrient absorption in the plant shoots, reduce Cd, Hg, and Pb translocation in plant shoots, and reduce Cd, Hg, and Pb in the tailings.
