The plants is under heavy environtmental stress due to the cutting of the trees for uses as a timber which worsen the existing degraded peat land condition. Therefore it is important to explore non-timber products of the gelam trees. The leaves is one of the most potential sources of non-timber products of the trees. Two types of the gelam growing in the degraded peat land of Central Kalimantan is identified, ie.: Melaleuca leucadendra (L.) L. and Melaleuca cajuputi Powell. The amount of the leaves that could be harvested is predicted in the order of 12.5 and 7.5 tons per hectar per year with the essential oil that could be produced at 64.8 kg and 86.4 kg for Melaleuca leucadendra (L.) L. and Melaleuca cajuputi Powell respectively. An analysis on active compound of the essential oil extracted from the leaves by GCMS showed that the oil of M. leucadendra (L.) L. contain γ-terpinen, α- terpinolene, caryophyllene, α-humulene and two unknown compound as its major components (5-25%). Whereas oil of M.cajuputi Powell contain mostly eucalyptol (1,8-cineol) (52-57%) with lesser amount (5-13%) of D-limonene, 4-terpineol and caryophyllene. High content of eucalyptol in the leaves of M.cajuputi Powell make this species as a potential plant for sustainable reforestration of the degraded peat land. While the gelam trees is maintained standing still, the leaves is allow to be pruned on a regular basis to produce high added value essential oil for feedstock of cosmetics and phamaceutical industries. This way, the trees for reforestration could also function as a means to provide income generation for local peoples who play important roles in conserving the peat land area in Central Kalimantan, Indonesia.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Central kalimantan,GCMS,Gelam tree,Non-timber products,Reforestation[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
