Abstract

Oil palm empty fruit bunches (OPEFB) are abundant lignocellulosic by-products with potential as ruminant feed, but their utilisation is limited by high fiber recalcitrance. This study aimed to evaluate the effect of autoclave treatment combined with alkaline pretreatments on the structural characteristics and fiber composition of OPEFB. Unlike previous studies that largely focused on biological delignification or advanced biomass fractionation, this study directly compared urea- and NaOH-assisted autoclave pretreatments by integrating FTIR, SEM, and Van Soest fiber fraction analyses. The experiment consisted of three treatments: untreated OPEFB (T1), OPEFB treated with autoclave and 3% (w/w) urea (T2), and OPEFB treated with autoclave and 3% (w/w) NaOH (T3). FTIR results showed that NaOH-assisted autoclaving caused the strongest weakening of O–H, C–H, C=O, and C–O–C absorption bands, suggesting partial disruption of functional groups associated with cellulose, hemicellulose, and lignin. SEM observations showed that T3 produced the most severe fiber surface disruption, with rough and fibrillated morphology. Fiber fraction analysis showed that T3 significantly reduced NDF, ADF, hemicellulose, lignin, and cellulose contents compared with T1 and T2 (p < 0.05). In conclusion, 3%(w/w)  NaOH-assisted autoclaving was more effective than 3% urea in modifying the lignocellulosic structure of OPEFB and may improve fiber accessibility. However, the substantial reduction in cellulose warrants cautious interpretation. Further evaluation of dry matter recovery, residual alkali, rumen fermentation, digestibility, and animal performance is required to confirm its practical value as a ruminant feed ingredient.

Abstract

Increasing broiler chicken populations in intensive rearing systems lead to excreta accumulation in litter, elevating ammonia levels and degrading housing environmental quality. Lemongrass (Cymbopogon nardus) contains bioactive compounds with strong antimicrobial properties and may serve as an effective natural litter additive. This study aimed to determine the effect of lemongrass addition on litter quality and environmental conditions of broiler chicken houses. Conducted from February 2 to March 9, 2026, at CV. Lestari Jaya Farm, Kubu Raya Regency, West Kalimantan, the research employed a Completely Randomized Design featuring five treatments and four replications: P0 (rice husk without lemongrass), P1 (5%), P2 (10%), P3 (15%), and P4 (20% lemongrass). Parameters observed included litter moisture content, ammonia concentration, pH, and temperature, analyzed using ANOVA followed by Duncan’s test at a 5% significance level. Results indicated that lemongrass addition significantly reduced ammonia concentration and litter pH ($P<0.05$), whereas moisture content (58–65%) and temperature (29.22–29.69°C) remained relatively stable. Ammonia levels ranged from 3.02–5.05 ppm, being lowest at P4 and highest at P0, while litter pH ranged from 6.45–7.10. In conclusion, 5% lemongrass is the minimum effective concentration to reduce ammonia levels and litter pH effectively.
