Potential uses of teak leaf litter for liquid smoke and of other utilizations: A review

Abstract

Abstract Teak (Tectona grandis) is one of the high-quality wood-producing trees. Large trees, straight trunk, large leafy, with the height reach 30-40 m. The nature and characteristics of teak trees usually drop their leaves every dry season, and this will cause problems for the surrounding community because the dry leaves fall into waste and have not been utilized properly. Waste of dried teak leaves will accumulate under the stands of teak trees, and in the dry season can be a trigger for forest fires. the teak leaves contain 48.51% bounded carbon, 6.61% moisture content, 31.72% ash content, 13.17% volatile content, and density 0.65 g/cm. In addition, teak leaves also contain flavonoid compounds, protein, nine phenolic acid or tannin compounds as well as crude fiber content covered in lignin of 22.9. Based on the content in the dry teak leaf litter waste, this paper presents an effort to use it into a number of useful products, one of which is the utilization of dry teak leaf litter waste for liquid smoke, and several other uses carried out by communities around the teak forest such as for charcoal briquettes, compost, medicine, and animal feed. Analysis of liquid smoke was carried out at the Integrated Laboratory of the Forest Products Research and Development Center using the Pyrolysis GCMS method. Meanwhile, other results are a review of several studies conducted by the community.
