Pengaruh Varietas Dan Umur Panen Terhadap Kualitas Serat Kenaf (Hibiscus Cannabinus L.)

---

ABSTRACT ABSTRACTABSTRACT ABSTRACT
Kenaf (Hibiscus cannabinus L.) is an important bast fiber crop widely used as raw material in various industries such as paper, geotextiles, fiberboard, and biocomposites. Fiber quality is strongly influenced by genetic factors and harvest age, which affect agronomic performance as well as the chemical composition of the fiber. This study aimed to analyze the effect of four kenaf varieties (Karang Ploso 6, Karang Ploso 9, Karang Ploso 14, and Kenafindo 2) and four harvest ages (75, 90, 105, and 120 days after planting) on growth characteristics and fiber quality. The experiment was conducted using a factorial randomized block design with six replications at the Experimental Field and Plant Breeding Laboratory, University of Riau, from January to May 2025. Parameters observed included flowering age, plant height, stem diameter, fresh plant weight, fresh stem weight, dry fiber weight, fiber ratio, and chemical composition (holocellulose, hemicellulose, alpha cellulose, and lignin). The results showed that both variety and harvest age significantly affected all observed parameters. Karang Ploso 14 and Kenafindo 2 demonstrated superior vegetative growth and fiber yield. Harvest at 120 days produced the highest biomass and dry fiber weight, while older harvests increased lignin content, reducing fiber softness. Kenafindo 2 at 120 days yielded the highest dry fiber (21.65 g) with favorable chemical composition (alpha cellulose 57.30% and lignin 14.55%). Overall, the optimal harvest age for balancing fiber yield and quality ranged from 110–120 days depending on variety.
Keywords: Kenaf, harvest age, varieties, bast fiber, lignocellulose, fiber quality
