Abstract

http://www.woodj.org -191 - INTRODUCTIONPersimmon (Diospyros kaki, family Ebenaceae) is a seasonal fruit-producing tree native to China, which later spread to Korea, Japan, and other parts of the world as a traditional crop and exotic fruit (Choudhary et al., 2022;Nazir et al., 2013;Yuniastuti et al., 2021). Persimmon tree has 15-17 m height unpruned and should not surpass 5-6 m height for cropping purposes (Baswarsiati et al., 2006;Intrigliolo et al., 2018). In Indonesia, persimmon trees are commonly found in several regions, including North Sumatra (Berastagi and Toba), West Java (Garut and Ciloto), Magetan, Malang, and East Java (Batu;Baswarsiati et al., 2006).Persimmon wood is suitable for high-quality furniture, sculptures, and musical instruments because of its unique color and physical characteristics (Kiaei and Bakhshi, 2014). The heartwood of D. kaki rarely forms black
