UTILIZATION OF WASTE OF PINE, SENGON, AND SURIAN SAWN INTO LIQUID SMOKE AS A BIOFERTILIZER OF ARABICA COFFEE SEEDLINGS (COFFEA ARABICA L.)
Indonesia is one of the active exporters of logs and sawn timber. The volume of wood always increases every year. In 2019, Indonesia exported more than 45.8 million m3 of logs and sawn timber volume of more than 2.5 million m3. Every wood industry will produce wood waste. There are 31.73 million m3/...

| Summary: | Indonesia is one of the active exporters of logs and sawn timber. The volume of wood always increases every year. In 2019, Indonesia exported more than 45.8 million m3 of logs and sawn timber volume of more than 2.5 million m3. Every wood industry will produce wood waste. There are 31.73 million m3/year of harvesting waste from forestry industry and plantation waste that can be processed into charcoal and wood vinegar products of 27.32 million m3/yr. The main objectives of this study are to determine the characteristics of the liquid smoke of pine, sengon, and surian wood waste, and to determine the response of the application of liquid smoke from sawn wood waste as a biofertilizer to Arabica coffee seedlings. Parameters measured included seedling height increase, seedling stem diameter, and number of coffee seed leaves. The experimental design used in this study is a factorial randomized block design with two treatments, namely the type of liquid smoke (pine, sengon, and surian) and concentration (2%, 2.5%, and 3%). This research is conducted with 3 replications. GCMS results show that there are 35 compounds in liquid smoke from pine wood waste, 26 compounds in liquid smoke from sengon wood waste, and 23 compounds in liquid smoke from surian wood waste. Pine liquid smoke has several compounds that act as biofertilizers, namely acetic acid, palmitic acid, oleic acid, stearic acid, 1-Phenanthrenecarboxylic acid, and propionic acid. While sengon liquid smoke contains acetic acid, o-Nitrobenzoic acid, and Ammonium carbamate which can affect the growth of coffee seedlings. And in surian liquid smoke, compounds that can affect the growth of coffee seedlings are acetic acid, propane dioic acid, palmitic acid, oleic acid, and Cyclohexanone. The pH level is in the range of 1.69 – 3.08. The acid content is in the range of 9.84 – 10.90%. N levels are in the range
of 0.54 – 1.59% while K levels are in the range of 111.13 – 153.4 ppm. The phenol content is in the range of 4423.94 – 7248.01 mg GAE/100g. The highest increase in height of coffee seedlings is produced by the application of 2.5% surian liquid smoke. While the best results for the increase in stem diameter from the application of 2% sengon liquid smoke. And the best result for increasing the number of leaves is 2% pine liquid smoke. |
