Abstract This study determined the chemical properties and calorific value of Timo ( Timoneus sericeus ) wood originated from Reknamo village, Timor Island, East Nusa Tenggara. Timo is a potential wood that belongs to the Rubiaceae family, categorised as the lesser known tree. Its basic wood properties have not been thoroughly scientifically investigated. The chemical wood analyses were carried out at the laboratory of chemical forest products in the Forest Products Research and Development Center, Bogor. The Testing methods were according to the ASTM and TAPPI standard, included the content of extractive solubility (in cold water, hot water, benzene-alcohol, and in 1% NaOH), cellulose, pentose, lignin, ash, and silica. The calorific value was measured by the calorimeter. The result showed that the cellulose, pentose, and extractive solubility contents of Timo wood were high; the lignin and ash contents were moderate; the silica content was low; the calorific value was high (4400 cal/g). Based on the results of chemical wood analyses and calorific value, Timo wood is qualified for construction and wood energy; while it is not recommended for pulp and bioethanol.
